Mega Man X - Maverick Bosses / Characters

The various animal and plant Maverick Reploids who serve as the main bosses of the Mega Man X series.

open/close all folders

All Mavericks

Beast Man: The majority of these Mavericks are Ridiculously Human Robots that resemble animals, with the occasional Plant Person, Mushroom Man, or what appears to be a humanoid in battle armor.
Brainwashed and Crazy: Due to the Maverick/Sigma Virus, for most cases, although it's shown most prominently in X3 and X5.
Cycle of Hurting: In many cases, using their Weakness weapon will make their AI trapped in a loop that makes them vulnerable to another Weakness weapon attack. Especially in case of Spark Mandrill who can be prevented completely from moving at all with his Weakness weapon, Shotgun Ice.
Dub Name Change: Many bosses have their names changed in the western release, with the Maverick themselves was known as Irregulars in the Japanese version. It gets egregious in the original X5 where the western names of the Mavericks are references to Guns N' Roses members. The ''Mega Man X: Maverick Hunter's Field Guide'' rectifies this by having the Japanese and the original western names of the X5 Mavericks be aliases the bosses use.
Face–Heel Turn: Many of the Mavericks you fought are former Hunters or otherwise-neutral civilians.
Heel–Face Turn: In the manga at least, several Mavericks can recover their senses and turn good again.
Four-Legged Insect: Most arthropod-based Mavericks just have two arms and two legs.
Fire Is Red: When you encounter a fire-based Maverick, expect them to be colored red or orange.
A Lizard Named "Liz": In the Japanese version, the bosses' names are corruptions of the name of the animal they represent. This is shown the most in X6 (see below) where the names mostly don't change overseas; you'd be hard pressed to find out what "Mijinion" would refer to.^note
Monogender Monsters: All of them are male.
Playing the Victim Card: Some play this trope when they aren't Brainwashed and Crazy.
Red Baron: Most, if not all of them have one each. They're mostly in the manual, though.
Something Person: Generally it's "Something Animal" (with occasional plant and fungus). Unlike the Robot Masters in the Classic series, several Maverick bosses can have the same "Something" word in their names, such as Flame Mammoth, Flame Stag, and Flame Hyenard.
Stock Animal Behavior: Many of the Mavericks have an attack based on a behavior of the animal they're based off. For example, Chill Penguin slides on the floor, Wheel Gator does the alligator death roll, Blast Hornet attacks with his stinger, etc.
Turns Red: They'll modify their pattern and whip out new strategies after their health goes below half. This usually comes with a Desperation Attack as well.

Mega Man X/Maverick Hunter X

General

Came Back Wrong: MHX interprets the refights in Sigma's Palace as actually reconstructions of the bodies which lack the mind of the original, and are therefore more robotic (ironically) than before. This may be implied in the Boss Rushes in the other games as well, except in X8 where they're just regular New Generation Reploids that shapeshift into the bosses.
Fallen Hero: All of them are former Maverick Hunters (though not all of their intentions have been pure).

Armored Armadillo

Steel Armored Warrior

"I'll fight you because it is my calling!"

Japanese Name: Armor Armage

An armadillo-based Reploid from the 8th Armored Division. He is an incredibly loyal soldier, possibly to a fault, following Sigma into his rebellion based on militaristic devotion alone. He occupies a mine that has been reopened to secure materials for war.

Weapon: Rolling Shield (X), Ball weapon system (Vile)

Weakness: Electric Spark

Voiced by: Kenta Miyake (JP), Noah Umholtz (EN)

Adaptational Heroism: In the Rockman X Irregular Report novel, rather than the unquestionably loyal soldier who followed his commander into rebellion, he alongside Storm Eagle served Sigma because he held their men hostage. Sadly, Vile executed their men while they were away.
Alliterative Name: In both versions.
Boss Vulnerability: He is only vulnerable when he is firing, or after he finishes his Rolling Attack. Once his armor is shorted out, however, so is his invulnerability.
Bouncing Battler: He rolls into a ball and bounces around the room.
Catch and Return: Attack him with a charged shot while he is guarding and he will absorb it, firing it out in a Spread Shot.
Energy Ball: The weapon X got from him. Its charged version is a full-body barrier.
Logical Weakness: All of his armor can be shorted out by a high-powered electrical charge, leaving him vulnerable. That said, it will only affect him when he is vulnerable.
Luckily, My Shield Will Protect Me: His armor protects him from all attacks even both the Hadoken and his weakness, the Electric Spark.
Minecart Madness: His stage is set in an Abandoned Mine with at least 3 mine carts that can carry X throughout the stage; the last one carries him to the boss door.
My Master, Right or Wrong: In the manga adaptation, fitting with his samurai-like personality in said adaptation.
Noble Demon: Shades of this appear in the manga adaptation where he has a fair fight with X, using katanas.
Painfully Slow Projectile: The energy cannon in his head fires shots that are noticeably very slow compared to most other attacks in the game.
Removable Shell: Using Electric Spark will short out and blow off his armor.
Rolling Attack: When he bounces around the place.
Spin to Deflect Stuff: While he is rolling around, he can't be damaged due to his armor. If you cracked his armor beforehand, though, he's vulnerable anytime.
Stock Animal Behavior: Rolling into a ball.
Undying Loyalty: Apparently, he goes with Sigma because, as the latter hasn't been officially pulled out of service, Sigma is technically still the leader of Maverick Hunters and thus just goes with him as the leader.
Armadillo: Whether [Sigma] is insane or not...it's not my place to judge him. I must obey!
Unusual Weapon Mounting: The top of his head has a gun. Not on, but inside◊.
Wild West Armadillo: Played with, as he is portrayed as a samurai.

Boomer(ang) Kuwanger

Space-Time Jumper

"If you've made it all the way up here, you must not be an ordinary B-Class Hunter."

A stag beetle-based Maverick Hunter from the 17th Elite Unit, the same unit as his brother Gravity Beetle, X, Vile, and fellow Maverick bosses, Spark Mandrill and Flame Stag. He has little sense of right and wrong, making decisions based only on logic. When Sigma rebelled, he used deductive reasoning and joined the rebellion. He occupies a tower monument and converts it into a military outpost.

Weapon: Boomerang Cutter (X), Cutter weapon system (Vile)

Weakness: Homing Torpedo

Voiced by: Hisashi Izumi (JP), Ethan Cole (EN)

Above Good and Evil: He bases his decisions on what is logical, not on what is good or evil. He sided with Sigma because he found it to be the most logical thing to do.
Adaptation Personality Change: In X1 he had no strong feelings about Sigma's rebellion and joined it out of a sort of nihilistic boredom. In Maverick Hunter X he instead found Sigma's sound logic compelling.
Big Creepy-Crawlies: He resembles a stag beetle, as his name implies.
Blood Knight: He considers both X and Vile to be interesting opponents to fight.
Boomerang Comeback: His Boomerang Cutter works this way. When used by X, it can even bring items back.
Brain Uploading: In the X1 manga, he uploaded his mind into his base's computers to operate his body at peak performance.
Dub Name Change: To "Boomerang Kuwanger" in Maverick Hunter X, but somewhat downplayed as they don't change the "Kuwanger" part.
Expy: Of Cut Man due to the scissor-like blades on his head that he throws like a boomerang, exactly as Cut Man does. Also has the feel of Quick Man with a quick attack style and boomerang weapon.
Grapple Move: He can do this to your player character with his horns.
Horn Attack: He can either throw his horns at you or, conversely, throw you away with his horn.
Horned Humanoid: As a stag beetle robot, he comes with the horns.
Japanese Beetle Brothers: With Gravity Beetle.
Logical Weakness: His fast speed won't help him dodge a homing projectile.
Mix-and-Match Critters: While he is mostly based on a stag beetle, his lean build and the triad of auxiliary eyes on his forehead are more evocative of some kind of wasp.
Multi-Directional Barrage: Charged Boomerang Cutter will send 4 big cutters to 4 directions that fly in an arc, covering large area.
Red Oni, Blue Oni: The Blue to Gravity Beetle's Red. Where Gravity Beetle acted out of a desire to avenge Kuwanger and fights with a more aggressive style using gravity balls and dashing horn-tossing attacks, Kuwanger acts based on logic and fights using a more tactical style with teleportation.
Spock Speak: Well-spoken at all times, and speaks with trains of logic.
Stock Animal Behavior: Throwing you with his Dead Lift move via his horns.
Super-Speed: Moves very quickly even when not teleporting.
Teleport Spam: Rapidly teleports around the room.
Tough Beetles: Based on a stag beetle, and he's strong enough to effortlessly lift X with his horn to throw him around.
The Tower: His stage is a communications tower made into his base of operations. X has to climb the walls inside, then take an elevator, climb the ladders outside, then go inside again before fighting him.
Utility Weapon: Boomerang Cutter can obtain hard-to-reach items. It can also cut off Octopus' tentacles and Mammoth's trunk, disabling attacks that use those appendages.
Villainous Friendship: He was good friends with Flame Stag, even joining up with him when Sigma declared war against humanity.
We Used to Be Friends: X tries to call off his fight against Kuwanger for this reason in Maverick Hunter X. It doesn't work.

Chill Penguin

Lord of the Snowy Plains

"Sigma has paid for the use of my power. Working for him is a million times better than piddling around on the South Pole with nothing to do."

Japanese Name: Icy Penguigo

A penguin Reploid from the 13th Polar Region Unit. Shortly before the rebellion began, Chill Penguin moved to the 17th Elite Unit to work directly under Sigma's command. The rebellion sounded fun to him, so he joined in order to escape his boring post at the South Pole. He now occupies a snowy missile base. There was strong animosity between him and Flame Mammoth.

Weapon: Shotgun Ice (X), Frozen Castle armor enhancement (Vile)

Weakness: Fire Wave

Voiced by: Ryuzo Ishino (JP, Maverick Hunter X), Dean Galloway (EN, Maverick Hunter X)

Breath Weapon: Can breathe an icy wind to create ice statues that block your shots. He also fires small icicles and Shotgun Ices from his mouth.
The Cameo: He appears in Frost Walrus' stage in X4, frozen in the background (specifically in the miniboss fight).
Fantastic Racism: Was apparently both on the giving and receiving end. In the X1 novelization, Penguin has disdain for X and other more humanoid Reploids for how he sees them as just bootlickers for the humans who look down upon them.
Green-Eyed Monster: In Maverick Hunter X, it is implied that Chill Penguin's involvement in the rebellion was partly due to his jealousy of X.
An Ice Person: Shoots ice shards, can summon a snowstorm, and creates ice sculptures.
It Amused Me: He joined Sigma because he found it more amusing than his job of "piddling around on the South Pole with nothing to do". He also said that Sigma "paid his price".
Logical Weakness:
- An Ice Maverick that doesn't take well to fire-based weapons. Penguin On Fire is the result.
- He allegedly doesn't get along well with Flame Mammoth, which is another hint.
Making a Splash: In DiVE, he gets a Summer variation where he attacks with waves and bursts of water.
The Napoleon: Is known for being belligerent and short-tempered, especially with big guys like Flame Mammoth.
Polar Penguins: He's a Reploid modeled after a king penguin and was built to operate in subzero temperatures.
Recursive Ammo: If Shotgun Ice hits a wall, 5 icicles will fan out from the impact.
Shaping Your Attacks: He can create ice copies of himself to be sicced at X or act as barriers to block X's attacks.
Shoulders of Doom: He has gigantic pauldrons that jut out from his shoulders.
Slide Attack: Slides on his stomach at you.
Slippy-Slidey Ice World: His stage is set in a base in a snowy mountain.
Stock Animal Behavior: Sliding around on his belly.
Super Sliding: Owing to his penguin-like design, Chill Penguin wil slide along the floor over his icy fortress to tackle X as well as send penguin-shaped ice sculptures at him. X can charge Chill Penguin's Shotgun Ice weapon to produce a sled made of ice that he can ride until it crashes into a wall or an enemy, upon which it shatters.
Utility Weapon: Charging his Shotgun Ice will give you a temporary ice slide which you can slide on.
Warmup Boss: He is the easiest boss in the game, mostly because of his long vulnerability periods and easily telegraphed attacks. In addition, since his stage contains the unavoidable dash upgrade, the player is heavily encouraged to play his level first.
Weak to Fire: As an ice-based boss, he doesn't take too well to the Fire Wave, taking extra damage and even catching fire when hit by it.

Flame Mammoth

Fiery Oil Tanker

"Bwah ha ha! There's nothing I like more than stomping weak little blabbermouths like you into dust!"

Japanese Name: Burnin' Noumander

A mammoth Maverick Hunter from the 4th Overland Unit. He had an arrogant and cocky attitude, and was extremely proud of his large size and strength. His tendency to look down on those smaller and weaker than him, put him on bad terms with his subordinates and Chill Penguin. He controls a factory that is making weapons for Sigma's army.

Weapon: Fire Wave (X), Flamethrower weapon system (Vile)

Weakness: Storm Tornado, Boomerang Cutter (the latter only for disabling some of his attacks)

Voiced by: Kenta Miyake (JP), Gerald Matthews (EN)

Acrofatic: Despite being large and fat, he can jump a distance of almost two screens. He is slow otherwise, though.
Adaptational Badass: In Maverick Hunter X he's actually a bit dangerous, as he can hit you when he jumps.
Adaptational Heroism: In the Shigeto Ikehara manga adaptation, he dies fighting a Maverick Chill Penguin before Sigma's rebellion goes into full swing (though because that manga adaptation was cut short, it is unknown if he really was truly loyal or if he just hated Chill Penguin so much that killing him while pretending to be a loyal Maverick Hunter was an opportunity he wasn't willing to pass up. Every other Maverick, including the normally morally conflicted ones, was on Sigma's side all along).
Animal Gender-Bender: Considering the sexual differences in elephants, including the species he is based on, his lack of tusks means that he is based on a female elephant rather than a bull elephant. This was averted in the first Mega Mission Carddass series where he is given a design based on a bull elephant with the inclusion of tusks as long as his trunk.
Arm Cannon: He shoots his Fire Wave from his right arm. So will you.
Conveyor Belt of Doom: In his boss room. He can change the direction of the belt as well by blowing his trunk.
Cruel Elephant: Flame Mammoth is very proud of his own power and looks down on smaller people.
Eternal Engine: He takes over a weapons factory, with lots of "junk" robots being carried around on belts and lots of molten metal pool.
Fat Bastard: Modeled after an elephant, has an arrogant and cocky attitude, and enjoys crushing and humiliating anyone weaker than himself.
Ground Pound: Flame Mammoth shakes the earth when he lands, knocking X off his feet for a few seconds and leaving him wide open for a direct fire attack.
Ground Wave: Charged Fire Wave creates a creeping wave of flame on the ground.
Hopping Machine: Despite his gigantic size, he moves only by jumping around.
Laser-Guided Karma: Due to treating his men from the 4th Overland Unit like crap during his days as a Maverick Hunter, when he joined Sigma's rebellion, the whole unit didn't follow suit, making them one of the only original Maverick Hunter units to not join Sigma.
Logical Weakness:
- Fire gets blown away by wind.
- Severing his trunk stops him from using his oil and fire attacks leaving only the Conveyor Belt of Doom and his stomping to worry about.
Oil Slick: He can place one on the conveyor belt that can be ignited by his fire attacks.
Playing with Fire: Shoots fireballs at you that ignite if they hit an oil patch.
Shockwave Stomp: Stuns the player when landing from his jumps.
Simpleton Voice: Voiced this way in Maverick Hunter X.
Sole Survivor: In the manga version, he is the only Maverick boss that survives X's counterattack.
Technicolor Fire: In Maverick Hunter X's Hard Mode, his fire projectiles turn blue, and will create a tall pillar of flame if they hits the ground.
This Was His True Form: In Iwamoto Yoshihiro's Rockman X manga, he is actually a tiny, spherical worker robot who built the "Flame Mammoth" body around himself out of scrap metal.
Warm-Up Boss: Puns aside, he is nearly as easy as Chill Penguin in X1, as he can only damage you with contact damage and a single projectile that he fires diagonally down towards the ground, limiting its range, and crippling its usefulness against X, who can climb walls. Combine these with his slow speed, and the fact that X's default weapon, which he always has access to, is an infinite-ammo full-screen attack, and you get a boss that it's easy to not even take damage against.

Launch Octopus

Military General of the Deep

"Maverick? How dare you call my artistic battle style by that name!"

Japanese Name: Launcher Octopauld

An octopus Reploid from the 6th Marine Unit. He has always believed in Reploid supremacy, and sees his explosive combat style as something worthy of being called art. Depending on the game, one of these led him to become a Maverick. His role is to obstruct sea traffic and assault cities based on the ocean.

Weapon: Homing Torpedo (X), Missile weapon system (Vile)

Weakness: Rolling Shield, Boomerang Cutter (for disabling some of his attacks)

Voiced by: Tetsuharu Ota (JP), Jonathan Love (EN)

Adaptational Backstory Change: In the original he joins Sigma's army as an excuse to finally live out his anti-human prejudice. In Maverick Hunter X he's a neglected artist who is brought into the army by Sigma's flattery.
Adaptation Personality Change: Originally a Fantastic Racist, in the reboot he's a Combat Aestheticist instead.
Berserk Button: He seems to be offended when X calls his fighting style "Maverick".
"Maverick? How dare you call my artistic battle style by that name!"
Bring It: A variation; his intro pose involves gesturing at X with one of his tentacles, and then at the ground, effectively saying, "You're going down".
Combat Tentacles: Which can be cut off with the Boomerang Cutter, leaving him unable to do anything besides jump around and firing his shoulder rockets.
Even Evil Has Loved Ones: Mega Man X5 reveals he had a brother, Volt Kraken ^noteAka Squid Alder, who was also a Maverick Hunter like him, though he quit to pursue other dreams and when told by X that Octopus was dead, he took it in stride, since Maverick Hunters fight and defeat Mavericks, and was going to give him Energy Cart needed for the Enigma laser cannon without a fight. Unfortunately, the Sigma Virus infects him and Kraken vows to avenge his brother.
Fish People: He's more of an octopus-person, but being an octopoid makes him one.
The Fighting Narcissist: In fact, he joined Sigma's rebellion after Sigma fed to his ego.
"I'll show you how an ARTISTE fights!"
Funnel-Mouthed Cephalopod: An octopus with a funnel-shaped mouth.
Homing Projectile: His homing fish (the Homing Torpedo).
Life Drain: His E-Drain move, although you can sever his tentacles with the Boomerang Cutter to stop him.
Logical Weakness:
- All of his homing weaponry doesn't do any good against a full-body shield.
- Severing his tentacles with Boomerang Cutter disables his E-Drain move since he can no longer get a strong enough hold on X.
Macross Missile Massacre: Isn't called Launch Octopus for nothing. He has two versions: One where he fires out a Spread Shot of non-homing rockets, and another where he fires out homing fish projectiles.
Sequential Boss: The final Mini-Boss of the level takes place just outside the Boss Corridor.
Shoulders of Doom: They're spiked to boot. Those spikes are also missiles.
Sissy Villain: Has shades of this in Maverick Hunter X, what with his somewhat effeminate voice, obsession with beauty and artistry, and borderline flirting with Vile.
Spell My Name With An S: His Japanese name was rendered as "Octopardo" in X5 when fighting against Volt Kraken. This was fixed in the Legacy Collection.
Tornado Move: His E-Drain move starts with him spinning around to create a whirlpool that sucks X or Vile into it. If Vile beats him, he'll gain the Splash Hit napalm which emulates the move.
Under the Sea: His stage is set in an underwater base, starting at the shores near it.
Underwater Boss Battle: He is fought in an underwater cave, with the surface far above.

Spark Mandrill

Lightning King of the Bullet Fists

"I don't like thinking either... maybe we can find the answer together... in battle!"

Japanese Name: Spark Mandriller

Spark Mandrill is a mandrill-based Reploid. He served in the 17th Elite Unit. When the rebellion began, his admittedly low intelligence made it easy for Sigma to sway him to his cause. Spark Mandrill takes over a power plant to redirect its power away from a city and towards his new master's forces instead.

Weapon: Electric Spark (X), the Rocket Punch weapon system (Vile)

Weakness: Shotgun Ice

Voiced by: Takashi Nagasako (JP), Randy Brososky (EN), Gary Chalk (Animated series)

Adaptational Dumbass: Seemed to just be lazy and simple-minded in X1, but in Maverick Hunter X he's a complete dimwit.
Affably Evil: Mandrill is not too bright, but he is still well-spoken; he only fights X because Sigma told him to.
Anti-Armor: His Electric Spark not only penetrates, but completely destroys Armored Armadillo's armor, leaving him vulnerable to attacks even while ostensibly defending himself.
Bare-Bottomed Monkey: The multicolored lights all over his body include a large blue one right on his rear end, in reference to the bare blue behind of the animal he's based on.
By the Lights of Their Eyes: A variation; his entrance animation involves darkening the room and then flashing the lights on his body before he reveals himself.
Cross Counter: A charged X Buster will send Spark Mandrill reeling back if it hits during his dash punch.
The Dragon: To Vile in the Mega Man (Ruby-Spears) animated series.
Dumb Muscle: From his information bio: "Possesses immense strength and a powerful electrical shock attack, but doesn't seem to be the sharpest tool in the shed." He even admits he is not very smart and does not like thinking, but feels that what Sigma is doing is right.
Eternal Engine: A different one from Flame Mammoth's stage, he sets up base in a power plant that experiences rolling blackouts.
Fantastic Racism: In the X1 novelization, Mandrill has a rather low opinion of humans for how he's expected to use his strength to power a city and otherwise provide for dependent humans rather than live his life as he sees fit.
Good Old Fisticuffs: Has a dashing punch as one of his attacks.
Ground Punch: His Electric Spark is done this way, by punching the ground with an electrified fist that sends 2 electric balls creeping along the floor and wall.
Heel–Face Turn: In the manga, after being defeated and realizing X was the ultimate Reploid, Mandrill immediately gave up and surrendered before he is killed by a hologram of Sigma.
Human Popsicle: What happens if he is hit by his weakness.
I Just Want to Be Free: In the novelization, he joins Sigma's rebellion since he doesn't want to serve humans anymore. He instead wants to do whatever he wants, even if it means hurting innocents.
Killer Gorilla: Although he is more of killer mandrill.
Logical Weakness: Mandrills live in tropical climates, thus hating the cold.
Shock and Awe: His Electric Spark weapon.
Smart Bomb: In the remake, the charged Electric Spark creates a full screen blast that decimates all enemies.
Stealth Pun: His drill punch attack in Maverick Hunter X may have something to do with his name. Also doubles as Meaningful Name.
Stock Animal Behavior: Swinging on the wires above like a monkey.
This Is a Drill: In Maverick Hunter X, he can turn his right arm into a drill knuckle.
Zero-Effort Boss: Although he's normally a tough fight, the player can just use his weakness to the Shotgun Ice to Stun Lock him until he dies.

Sting Chameleon

Spirit Sharp-Shooter of the Haunted Forest

"Maverick, Schmaverick! I don't care so long as I make my mark!"

Japanese Name: Sting Chameleao

A chameleon in charge of the 9th Special Forces. He's a conniving trickster who claims to only respect the strong, and doesn't care if he's considered Maverick or not so long as he makes a mark on the world. He controls a forest base on the front-lines of the rebellion.

Weapon: Chameleon Sting (X), the Laser weapons system (Vile)

Weakness: Boomerang Cutter

Voiced by: Hiroshi Shimozaki (JP), Roger Rhodes (EN)

Bring It: When beginning his boss fight against X or Vile.
"I'm ready!"
The Cameo: Appears as one of Metal Shark Player's attacks in X6.
Combat Pragmatist: His credo is "to fight by any means necessary".
Confusion Fu: His pattern is rather unpredictable, with him leaping to random directions in the air, or leaping right towards you on the ground, or becoming invisible and reappearing close to you for his tongue lash attack.
Cycle of Hurting: If you hit him with his weakness, he'll respond by dropping to the ground, and then doing his 'hang from the ceiling and shake to make spikes fall' attack. Thing is, he hangs low enough to get hit by his weakness when doing this, and the actually-damaging portion of that maneuver doesn't start until after his Mercy Invincibility wears off, so X can very easily lock him into one of these.
Energy Weapon: Chameleon Sting shoots green laser beams.
Giggling Villain: Giggles a lot in his boss fight.
Green and Mean: He practically trolls X when they meet, especially in the remake.
Hidden Depths: Implied. In Maverick Hunter X he conjectures that some of Sigma's servants may be blackmailed into loyalty by Hostage Situations. Whether Chameleon himself is fighting for hostages or if he was simply bluffing to mess with X is unknown.
Hollywood Chameleons: His camouflage is nearly perfect, only distorting the wall behind him, a la The Predator. Then again, he is a robot.
Invisibility: Blends into the background to vanish.
I Shall Taunt You: In Maverick Hunter X, most of his in-battle sounds are basically "nyeh nyeh" taunts, presumably trying to goad or mock X (and annoy the player).
Jungle Japes: His stage is set in a jungle with a small swamp near the end.
Light 'em Up: His Chameleon Sting is a spread of high-level optical laser beams.
Light Is Not Good: Has light based abilities (invisibility cloak), a light based weapon (see above), and is one of the villains.
Lizard Folk: Being a chameleon robot makes him one.
Logical Weakness: Hanging by the tongue makes him vulnerable to a cutting weapon. Invisibility also doesn't mean much in the face of a weapon that hits a wide area.
Mad Scientist: In the novelization. X and Zero face some of his handiwork within his forest base.
Maniac Tongue: On top of being a chameleon with the tongue to match, he's also quite the maniac.
Multipurpose Tongue: Uses it to attack X as well as hang from the ceiling.
Overly-Long Tongue: He's a chameleon.
Spread Shot: His Chameleon Sting shoots in three directions. Vile's default laser weapon Cerberus Phantom is its practical duplicate.
Stock Animal Behavior: Attacking you with his tongue, as well as turning invisible.
Unusual Weapon Mounting: He apparently fires Chameleon Stings from his tail.
Utility Weapon: Charging up Chameleon Sting effectively makes you completely invulnerable for a brief period of time.
Villain Respect: A rare case in which a villain has respect for another villain, Chameleon has nothing but respect for Vile, due to their methods of fighting dirty.^noteinvoked
Wall Crawl: When turning invisible.
We Used to Be Friends: With Vile, even admitting he had respect for Sigma's on and off right hand man. When Vile tries to tell Chameleon to let him pass without a fight, the Maverick laughs him off, saying they're gonna have to fight anyway and Vile reluctantly agrees.

Storm Eagle

Prince of the Skies

"Forgive me, X... I... I must defeat you!"

Japanese Name: Storm Eagleed

Once the noble and popular eagle-Reploid leader of the 7th Air Cavalry unit, he was forced into submission after a failed attempt at stopping Sigma's rebellion. Because of this failure, he loyally yet reluctantly agreed to follow Sigma in his rebellion. He controls an airport and obstructs air traffic with the fearsome Death Rogumer airship.

Weapon: Storm Tornado (X), Speed Devil armor enhancement (Vile)

Weakness: Chameleon Sting

Voiced by: Daisuke Kageura (JP), Tommy James (EN)

Adaptational Heroism: In the manga, rather than a Reluctant Monster forced to serve Sigma, he was the Maverick Hunters' inside man forced to not blow his cover until too late.
Affably Evil: In Maverick Hunter X's Hard Mode, he accepts the fact he's gone full-on Maverick, but still treats X respectfully and politely tells him he wouldn't hold back.
Airborne Mook: Fights you in the sky.
Anti-Villain: In stark contrast to every other Maverick, he's only following Sigma because Sigma defeated him and forced him to.
Apologetic Attacker: In Maverick Hunter X , he's unable to muster words before apologizing to X for battling him. This because Sigma forced him into going rogue.
Arm Cannon: Uses it to fire his Storm Tornado attack.
Bird People: He's a humanoid avian robot.
Blow You Away: Aside from Storm Tornado, he can blow simple wind currents as well to push you away.
The Cameo: Appears as the charged version of Metal Anchor in X6.
Combat Pragmatist: His fighting style isn't known for damage output. Half of his moves don't even inflict damage, but are instead designed to simply push X off his ship/platform.
Cool Airship: The Death Rogumer, which is also his stage.
Fake Defector: In the manga at least. Unfortunately, he does a little too good a job keeping up appearances.
Feathered Fiend: Flies to dive, and flaps his wings to create hostile air currents.
Feather Flechettes: In Maverick Hunter X's Hard Mode. While he's trying to blow you backward.
High-Altitude Battle: You fight him aboard his airship. The real danger of the fight isn't that his attacks inflict damage, it's staying on the airship as he tries to blow you off it for a Ring Out.
Logical Weakness: As agile and graceful as he is, even he can't outrun a laser attack. Additionally, birds hate thorns due to being unable to perch on them.
Mister Seahorse: He has a move where he spits out an egg that hatches into four small birds.
My Master, Right or Wrong: Follows Sigma even knowing he's gone Maverick, and even then it's clear he'd still be on X's side if he thought he had a choice in the matter.
Noble Bird of Prey: He's characterized as such, only going along with Sigma out of a sense of obligation, rather than a desire to go rogue and cause mayhem.
Reluctant Monster: He doesn't actually like or agree with what he's doing, but because he lost a fight against Sigma, he is forced to be loyal to his cause.
Stock Animal Behavior: Swooping.
Took a Level in Badass:
- In the original game he's noted to be rather easy as long as you mind the arena's edge. In Maverick Hunter X he's taken a few cues from fellow aerial Reploid The Skiver, doing horizontal charges that deal a lot of knockback and creating stationary tornadoes on the ground, along with his diagonal dive now stopping at ground level and going back up into the air which can trip up the player. As noted above he can also rain energy feathers that remain in the ground for a few seconds and damage X if touched, and they're often present while he's using his dives and wind attacks.
- Strangely, Storm Tornado is much better in X's hands than it is Storm Eagle's. When he uses it, it merely pushes you. When you use it, it's one of the strongest Maverick-acquired weapons in the series.
Tornado Move: Storm Tornado. Ironically this move is much better when X uses it, as it actually damages its target.
Winged Humanoid: Six limbs: two wings, two arms, two legs.
Wind from Beneath My Wings: He can flap his wings to push X backward.

Mega Man X2

Bubble Crab

Pulverizing Demon of the Ocean Depths

"A pirate girl!? This ain't a kid's errand! You should be willing to die for this business!"

Japanese Name: Bubbly Crablos

A crab-based Reploid, Bubble Crab previously served in the 6th Naval Unit along with Wheel Gator. Being extremely avaricious, his only motivation is to amass great wealth, he joined Sigma's rebellion seeing it as his big break. He was put in charge of transportation and tasked with defending a deep-sea submarine base.

Weapon: Bubble Splash

Weakness: Spin Wheel

Arch-Enemy: In the manga, he sees Marty as this due to being a Pirate Girl. And sure enough, pirates are known for plundering treasures.
Aquatic Mook: You fight him underwater, although the water level changes.
Bad Boss: He acts like an ill-tempered crime boss in the X2 manga.
Bubble Gun: His Bubble Splash.
Cephalothorax: He is essentially a Waddling Head with arms.
Fish People: Well, crab person. Being a humanoid robot crab makes him one.
Giant Enemy Crab: Actually he is one of the smaller bosses, but is still a crab and bigger than you.
Greed: Joined Sigma's forces and the X-Hunters solely because he wanted to get rich.
Laser Crab Claws: Extends them from the orbs on his head and jumps to attack you when you're above him.
Logical Weakness: A spiked wheel could easily crack a crab's shell and pop bubbles. He also allegedly hates working with Wheel Gator.
Making a Splash: Bubble Splash shoots a stream of bubbles.
Only in It for the Money: His main motivation to join Sigma's forces was to amass huge amounts of money.
Penny-Pinching Crab: A crab-themed boss who only worked for the villains because they paid him enough.
Power Pincers: Despite being a crab, he actually lacks these normally. When he does generate them, they're only used as spiked shoulders to pierce X, not pinch him.
The Remnant: One of the Maverick Hunters who defected during Sigma's rebellion.
Spiked Shoulders of Doom: Which he can project laser crab claws from.
Stock Animal Behavior: Blowing bubbles, as well as walking sideways.
Tactical Suicide Boss:
- Will do an upwards attack every single time X goes directly above him. Thing is, this attack forces him to drop his shield, meaning a player who's mastered X's aerial movement can literally compel Bubble Crab to drop his (otherwise only vulnerable to his weakness) shield as much as they want.
- He constantly jumps from side to side during the battle. The Spin Wheel constantly rolls along the ground, and it's possibly for him to follow the wheel and either land in its path or right on top of it. You can score multiple hits with the same wheel.
Under the Sea: His stage has you going to the sea, trying to catch up with his submarine.
Underwater Boss Battle: The water level does change during his fight.
Utility Weapon: Charging up Bubble Splash gives you a bubble shield, which makes you jump higher underwater.

Crystal Snail

Crystal Magician

"Beauty is eternal. And therefore, its end will have an unimaginable luster. So thanks to you, I've learned a new form of beauty. But I won't thank you! I'll never forgive you for shattering the only support for the spirit of someone ugly such as myself!

Japanese Name: Crystar Mymine

A garden snail-based Reploid whose origins and motives are a mystery. He guards the Energen Crystal Mine under the X-Hunters' command.

Weapon: Crystal Hunter

Weakness: Magnet Mine

Big Creepy-Crawlies: He is a human-sized snail Maverick.
Boss Vulnerability: Can't be damaged in his shell.
Crystal Landscape: His stage is set in a cave full of colorful crystals.
Crystal Prison: His Crystal Hunter does this to X.
Dirty Coward: Without his shell to protect him from X's attacks, he doesn't even try to fight and will ignore X to try and climb back inside, only resuming attacking once he's safe again.
Gameplay and Story Segregation: His speed is listed as 500rp, by far the slowest of any boss in the game. This is a complete lie — not only does he rocket around the room using his shell as a booster pack, but when blown out of his shell by a Magnet Mine he begins rapidly jumping and dashing around the room to get back into it.
Gemstone Assault: Crystal Hunter shoots gooey crystalline drops.
Hidden Depths: In the X2 manga, he sees himself as ugly and is enamored with the Magna Quartz. When X destroyed it, he flips out.
Logical Weakness: A shell or crystal can't protect you from magnetism, and both get shattered by explosives. The magnetism also shorts out his time-scrambling abilities.
Luckily, My Shield Will Protect Me: Can't be damaged when in his shell.
Removable Shell: Hit him with the Magnet Mine and it separates him from his shell.
Shed Armor, Gain Speed: If you manage to knock his shell off with Magnet Mine, he'll move much faster, trying to get the shell again.
Stealth Pun: Everything about him (well, except for when he's without the shell) plays in "a snail's pace". If you don't have/use Magnet Mine or the buster upgrade, your fight with him will be dragged on for long due to his protective shell, his Crystal Hunter stuns its victims in place and its charged version slows everything down.
Stock Animal Behavior: Retracting into his shell.
Time Master: Subverted in the manga. While he looks like he's slowing down time, the manga shows that he actually causes crystals to form around X's body and hamper his movements. Charged Crystal Hunter naturally does the same, giving you the illusion of slowing the enemy movements.
Utility Weapon: Enemies frozen by Crystal Hunter can be used as Improvised Platform, and dashing into the frozen enemy to destroy them guarantees that they'll drop weapon energy.
Villainous Breakdown: When you knock him out of his shell with a Magnet Mine, he goes nuts and starts bounding around the room and dashing about trying to get back to it, foregoing all methods of attack until he's safely back inside.

Flame Stag

Heat Knuckle Champion

"That's right! I'll wipe away my shame with your life!"

Japanese Name: Flame Stagger

A white-tailed deer-based Reploid. Stag is a former member of the 17th Elite Unit who was with Boomer Kuwanger in Sigma's first rebellion. Afterwards his whereabouts were unknown, but he later resurfaced occupying an active volcano with the intent of triggering an eruption to block the sun with volcanic ash.

Weapon: Speed Burner/Rushing Burner

Weakness: Bubble Splash

A.I. Breaker: Getting hit by Bubble Splash causes him to always respond by throwing a one-two punch of fireballs, the first of which can be jumped over to hit him again before he can throw the second.
Bambification: One of the aversions in media, where he is a villain and a brawler and definitely neither sweet nor innocent. Also an aversion of The Marvelous Deer.
Desperation Attack: His flames turn blue, and he gets a Meteor Move should he successfully rush X.
Elemental Punch: His fists have flames spewing from them, and he can punch fire at you.
Good Old Fisticuffs: Uses them to punch fireballs at you.
Lethal Lava Land: His stage is set around a volcano.
Logical Weakness: Fire gets put out by water bubbles.
Jerkass: Back when he was a Hunter in the manga, he has been shown bullying rookies. Being a Sore Loser towards X in their first confrontation doesn't help.
Meteor Move: Does this to X if his Desperation Attack successfully connects.
Playing with Fire: Throws fireballs at you and leaves flames when he dashes.
The Remnant: One of the Maverick Hunters who defected during Sigma's rebellion.
Sore Loser: Being defeated by X while he was still a Hunter in the manga is his other reason for joining Sigma's rebellion.
Stock Animal Behavior: Charging at you.
Technicolor Fire: His fire turns blue once his health gets low.
Utility Weapon: A Charged Speed Burner is essentially the precursor to the Nova Strike, and can be used immediately after a normal dash for a longer air coverage.
Villainous Friendship: He was friends with Boomer Kuwanger during their time in the 17th Elite Unit before Sigma's rebellion, and if The Dawn of X is anything to go by, Stag was also friends with Kuwanger's brother Gravity Beetle.
Wall Jump: Can do so to avoid you.
Wreathed in Flames: In his flaming charge attack. Also done with the charged Speed Burner.
You Have Outlived Your Usefulness: In the manga, Agile kills him after his body upgrade goes out of control.

Magna Centipede

Crimson Assassin

"Huh? But I'm Silky, the one who asked you for help. But you know... that was just a facade. Don't you get it? This was all an act to kill you: a charade created by the great Magna Centipede!"

Japanese Name: Magne Hyakulegger

A centipede-based Reploid, former member of the 0th Special Unit who was captured by Mavericks and reprogrammed. After going Maverick, Centipede was stationed at the Central Computer center to work on transmitting the Maverick Virus through networks around the world.

Brainwashed and Crazy: Unwillingly reprogrammed to be loyal to Sigma after being captured during the latter's first uprising.
The Cameo: Appears as one of Metal Shark Player's attacks in X6.

Decoy Damsel: Disguises himself as a female Reploid named Silky to lure X to his doom during the events of the X2 manga.
Energy Absorption: Charged Magnet Mine can absorb enemy's shots towards itself.
Logical Weakness: Two ways - magnets can attract unwanted junk, and useless scrap is the antithesis to his high-tech ways. Alternatively, feeding him junk data overloads him.
Magnetism Manipulation: His Magnet Mine homes in on X.
Multi-Armed and Dangerous: Has four arms, which he uses to beat Alex Kidd and Stella in rock-paper-scissors.
Ninja Pirate Zombie Robot: A ninja hacker centipede robot!
Ninja: Is capable of teleportation and stealth operations, such as sneaking into the central computer system and hacking it. He also was part of the 0th Special Unit, which specializes in covert operations.
One Bullet at a Time: If he grabs X with his pincers, he'll inject him with a virus to prevent X from charging or firing multiple buster shots at once.
Optional Stealth: His stage has sensor lights that will go off and activate the security systems if you're detected. You don't have to play stealthily, but doing so will make it easier to reach the end.
Player-Guided Missile: His Magnet Mine can be controlled to go up or down by the player.
The Remnant: The only Maverick boss in the game who didn't defect during Sigma's rebellion, since he was captured against his will.
Rock Beats Laser: A technologically-skilled robot that teleports and uses homing mines is weak to scrap metal. In fact, it disables his tail.
Sticky Bomb: His Magnet Mine can stick onto walls, ceilings and enemies before exploding.
Teleport Spam: Warps around the room throughout the battle.

Morph Moth

Fallen Angel of the Island of Dreams

"I didn't conjure these illusions. My scales are the embodiment of the weakness in your heart. These illusions are your weakness!"

Japanese Name: Metamor Mothmeanos

A bagworm moth-based Reploid of unknown origin. He has the ability to metamorph his body by absorbing scrap from other Reploids, robots, and machinery. Under the X-Hunters' orders, he occupies a junkyard and uses the materials there to create an army of scrap Reploids.

Weapon: Silk Shot/Scrap Shoot

Weakness: Speed Burner/Rushing Burner

Abnormal Ammo: He manipulates scrap metal as weapon.
Airborne Mook: During the second half of the fight.
All-Encompassing Mantle: During his first phase, Morth Moth conceals his body in a cloak of purple metal log-like things, making him resemble a bagworm. Morth Moth sheds this during the transition to his second phase.
Big Creepy-Crawlies: He is obviously a giant bagworm moth.
Body of Bodies: His cocoon form is made of scraps absorbed from destroyed Reploids and Mechaniloids. The Garakuta enemies in his stage are essentially a mishmash of robot bodies put together.
Call-Back: Being a Reploid themed around scrap metal and awarding X a weapon based upon throwing scraps, he is like a successor of sorts to Dust Man. In story, he is also like a chronological successor to Junk Man.
Chasing Your Tail: In his cocoon form, he fires a line of junk that you must avoid by going in a circle.
Dishing Out Dirt: The Silk Shot can attract stones when you use it in a rocky area.
Down in the Dumps: His stage is set in a recycling factory around a junkyard.
Extra-ore-dinary: Silk Shot mainly collects and shoots scrap metal. Sometimes, however, it might attract rocks, leaves or crystals depending on the stage.
Gemstone Assault: You attract crystals if you use the Silk Shot in a mineshaft, such as Crystal Snail's stage.
Green Thumb: Use the Silk Shot in a forest-type stage and you attract leaves.
Identical Stranger: His design in his first form makes him look slightly similar to the first Wily Castle boss in Mega Man 8 and the first Fortress boss in Mega Man & Bass.
Item Caddy: A charged Silk Shot can be used to attract hidden weapon and energy capsules in certain rooms.
Logical Weakness: Junk-based robots don't take well to incineration. Cocoon/Moth On Fire is the result.
Macabre Moth Motif: Based on a moth, and a Maverick. He even has the metamorphosis theme played straight too.
Metamorphosis Monster: His entire battle is him metamorphosing into an adult moth.
Moth Menace: A moth Maverick who builds himself from scrapped Reploids and resurrects them.
Non-Indicative Name: In the English version only, Silk Shot summons scraps and other debris.
One-Winged Angel: First you fight his larvae form, then he morphs into his moth form for the second half of the fight.
Situational Damage Attack: Depending on the stage, the weapon he gives X can take on different forms, sometimes stronger or weaker. The X-Hunters also recieve varying damage depending on the scraps it summons.
Stock Animal Behavior: Dropping sparkling dust in his moth form as he flies around.
Utility Weapon: Using a charged Silk Shot in secret rooms to attract large amounts of Life Energy.
Wave-Motion Gun: In his moth form, he can shoot a laser beam from his palms.
Weak to Fire: Due to being made of junk, he gets incinerated by the Speed Burner, taking extra damage and even catching fire when hit by it.
Winged Humanoid: Comes with the wings in his moth form, being a moth robot and all.
You Will Not Evade Me: Thought yourself very clever by just clinging to the wall in the fight against Morph Moth? No biggie. He'll just fly up to where you are and poke you to death.

Overdrive Ostrich

Swift Runner of the Sandy Plains

"Caw caw caw! Not only did you uncover the sky, which I hated, but you even shot down the missile! Damn you, X... you piss me off to the highest degree!"

Japanese Name: Sonic Ostreague

An ostrich-based Reploid, formerly a member of the 7th Airborne Unit who resigned after an accident that cost him the ability to fly. Sigma later sought to recruit him, seeing use for his superior speed. Ostrich, sensing appreciation for his abilities, pledged his loyalty to Sigma and was stationed at a missile base in the desert.

Weapon: Sonic Slicer

Weakness: Crystal Hunter

A.I. Breaker: Crystal Hunter causes him to always jump and fire his Sonic Slicers upward in response. By hitting him with it again before he can shoot, Ostrich can be locked into never attacking.
Alliterative Name: in the western version at least.
Bird People: An ostrich robot.
Death from Above: He has 2 attacks coming from above - 1) he comes back in by running in the background then jumping into the air and landing on X, and 2) he fires Sonic Slicers upwards that then rain down. Charged Sonic Slicer for X does a similar thing.
Dented Iron: Joking aside, he is formidable despite being partially crippled after his accident.
Five-Second Foreshadowing: He can be spotted racing in the background before jumping to the fore to face X.
Foe-Tossing Charge: Get hit by him while he's running and you'll be knocked far backward!
Handicapped Badass: He was once able to fly but got in an accident. Also a nod to real-life, where ostriches are incapable of flying.
Jet Pack: As revealed in the X2 manga, Ostrich can fly with a pair of built-in jet engines on his back.
Logical Weakness: An enemy all about speed isn't nearly so threatening when he can't move.
Razor Wind: His Sonic Slicer.
The Remnant: One of the Maverick Hunters who defected during Sigma's rebellion.
Revenge: In the manga, Ostrich joins Sigma to avenge Storm Eagle (not knowing that Sigma was the reason Storm Eagle had to fight X in the first place).
Riding the Bomb: In a scripted event, X jumps onto a missile and destroys it before dropping down to the desert to encounter Ostrich.
Spread Shot: Normal Sonic Slicer fires 2 shots that reflects off walls, floors and ceilings. Charged up, 5 bigger shots are fired up which then fall, covering a wide area.
Shifting Sand Land: His stage is set in a desert, where you can find Ride Chasers that lets you ride through sandstorms.
Stock Animal Behavior: Running around really fast.
Super-Speed: Runs so fast he can knock you across the screen.

Wheel Gator

Evil Fanged Heavy Tank

"You're broken, aren't you? Such foolishness. You might as well be empty-handed. But you know, rest assured. I'll go easy on you! So I could have my sweet time killing you!"

Japanese Name: Wheel Alligates

An alligator-based Reploid who served as an officer of the 6th Naval Unit. Gator was later discharged, hunted as a Maverick and a traitor after viciously attacking a fellow Hunter. To satisfy his destructive impulses, he joined the X-Hunters' army and was given control of a massive tank modeled on a dinosaur with which to raze an entire city.

Weapon: Spin Wheel

Weakness: Strike Chain

A.I. Breaker: Getting hit with Strike Chain causes him to immediately submerge, with a brief window for a second hit on the way down. Unlike nearly all other examples, this actually makes the fight with Gator longer and harder instead of shorter and easier.
Blood Knight: Due to his ferocious nature, Gator attacked a fellow Hunter during a mission and was later hunted as a traitor. To satisfy his destructive impulses, he joined Sigma's Maverick army.
Deadly Disc: His Spin Wheel attack.
Desperation Attack: Jumps into the air, and spins like a drill to drill non-lethal spikes into the wall.
Eat the Bomb: He can eat semi-charged buster shots and spit them back out as energy projectiles.
Lizard Folk: A robotic version at least, being an alligator robot and all.
Logical Weakness:
- When gators are caught in the wild, one of the first things to do is tie/chain its mouth shut. However, it does provoke Wheel Gator into immediately submerging, actually drawing out the fight. Furthermore, an enemy that hides in liquid wouldn't like being forcibly pulled out.
- Wheel Gator can only eat and absorb energy attacks, not physical ones.
Multi-Directional Barrage: Charged Spin Wheel shoots out multiple laser beams from a big wheel to 8 directions.
Never Smile at a Crocodile: He's always got a grin on.
Oil Slick: His arena is a pool of oil (at least it looks like oil) that slows X down and leaves him open for a bite.
The Remnant: One of the Maverick Hunters who defected during Sigma's rebellion from the first game.
Shoulders of Doom: Like Metal Man, his shoulders have buzzsaws on them. Unlike Metal Man, he can actually fire blades from there.
Stock Animal Behavior: Using the death roll to drill the wall, as well as leaping out of the oil to grab X.
Tank Goodness: His level is an enormous dinosaur-based tank. You're basically raiding it to get to him.
Utility Weapon: Spin Wheel can dig through false floors/walls, revealing secret areas.

Wire Sponge

Little Demon of the Green Forest

"Oh? Do we have a guest? Why don't you come over here and dance with me."

Japanese Name: Wire Hetimarl

A luffa-based Reploid. He was created in a Maverick-producing factory, but an accident resulted in him developing an unintentionally childish and sadistic temperament. Sponge was placed in charge of the Weather Control Station, where he found delight in passing the time playing with the weather system.

Weapon: Strike Chain

Weakness: Sonic Slicer

Chain Pain: His Strike Chain shoots a chain out.
Death by Cameo: His body was apparently left to rot after being defeated, and by Mega Man ZX his body had grown into a giant stalk that dominates the Tower of Verdure.
Desperation Attack: Electrifies himself and sends down a lightning storm.
Grappling-Hook Pistol: When X gets Strike Chain from him, it allows him to use the chain as a grappling hook. Wire Sponge himself also uses his chains to grapple towards the ceiling and walls.
Half the Man He Used to Be: If you land the finishing blow with the Sonic Slicer. Oddly, despite this only being the second game, he's the only Maverick in the series who actually has a unique death scene if you kill him with his weakness.
Logical Weakness: Both plants and wires can be easily cut through with a sharp blade.
Manchild: An production accident resulted in him having a personality disorder, which causes him to be childish and easily amused.
Plant Person: He is based on a Loofah/Luffa sponge ("Hechima" in Japan, hence his Japanese name), not a sea sponge.
Shock and Awe: His Desperation Attack.
Spin to Deflect Stuff: Spins his Strike Chain in front of him to block attacks.
Spared by the Adaptation: The only X2 Maverick in the manga who is spared from being killed by X. Justified, since Dr. Cain told X that Wire Sponge is too scared to fight at this point.
Turns Red: Literally, at a certain point in the battle, combined with Burning with Anger, as steam will come out of... well where his ears should be during the process.
Utility Weapon: Strike Chain is a retractable Grappling-Hook Pistol that can be used to either zip to the wall or grab items from a distance. Downplayed in that, aside from some Sequence Breaking to get the X-Buster upgrade early on, there's no time when you need to use the Strike Chain to reach an area.
Warm-Up Boss: With a simple attack pattern, he's an ideal Maverick to select first. Also, all of the upgrades in the stage can be collected without needing any armor or weapon upgrades.
Weather-Control Machine: His stage features crystals that change the weather of the region, and in battle he can summon lightning.

Mega Man X3

Blast Hornet

Flying Spy of Shadow

"Overconfident as ever, I see! How's that? Nice armor, right? Your weapons are no match for me! I even had this room custom-made for your execution. Mr. Doppler is so generous!"

Japanese Name: Explose Horneck

A hornet-based Reploid and former second-in-command of the Special 0 Unit. When his superior Zero received an invitation to visit Dopple Town, Blast Hornet went in his place as Zero was busy. There, Blast Hornet fell victim to the Maverick Virus and joined Dr. Doppler's army. He now controls a factory that creates soldiers and weapons for the war.

Weapon: Parasitic Bomb

Weakness: Gravity Well/Bug Hole

Airborne Mook: Never touches the ground, unless you hit him with a charged Gravity Well.
Arm Cannon: Uses it to fire shuriken bees!
Bee-Bee Gun: Fires out bees that stick to X as well as homing bees.
Beware My Stinger Tail: As expected from a bee, he can sometimes fly directly at you to sting with his tail.
Big Creepy-Crawlies: He is much taller than X or Zero.
Brainwashed and Crazy: Both in the games and the manga.
The Cameo: Appears as one of Metal Shark Player's attacks in X6.
Crosshair Aware: When his health gets low enough, he sends out a crosshair which his bees will home into. It is also available to X as a Charged Attack.
Cyber Ninja: A ninja hornet robot who throws exploding hornet bombs like shuriken.
Heel–Face Turn: In the manga.
Logical Weakness: Really hard to fly if gravity is forcibly pulling you down to the ground.
Ninja: Moves stealthily and throws shuriken-Esque hornets. He's also a part of the 0th special unit, which specializes in covert operations.
Ninja Pirate Zombie Robot: A ninja hornet robot!
Personal Space Invader: His robot bees can latch onto you to deal extra damage.
Spread Shot: He can fire robotic bees in a spread-out fashion.
Stock Animal Behavior: Attacking with his stinger.
Throw the Mook at Them: A variant: uncharged Parasitic Bomb, when it hits an enemy (small ones, at least), will drag said enemy into another closest one, damaging them both.
The Unfought: Zero fought him instead of X in the X3 manga.
Wicked Wasps: A Maverick based on a hornet.
Winged Humanoid: Comes with being a hornet robot and all.

Blizzard Buffalo

Silvery Snowman

"You don't even know what you're talking about. Don't tell me what to do with my art."

Japanese Name: Frozen Buffalio

A water buffalo-based Reploid who was created for ski slope security and designed to operate in extreme cold. Despite his intimidating appearance, Buffalo is a gentle artist whose hobby is making ice sculptures. However, after coming to Dopple Town upon invitation, Buffalo was infected with the Maverick Virus and became a member of Dr. Doppler's army. In his rampage, he has frozen an entire residential area.

Weapon: Frost Shield

Weakness: Parasitic Bomb

A.I. Breaker: Buffalo can be made to repeatedly ram the wall behind him if you stay higher in the air than his height, which can be accomplished with the upward air dash.
Alliterative Name: In the western version at least.
Ascended Extra: He appears not just one, but two manga adaptations of the third and fourth games.
Back for the Dead: Shows up in the X4 manga to assist X in fighting Frost Walrus...only to end up Taking the Bullet for X.
Brainwashed and Crazy: Both in the game and the manga.
Bullfight Boss: He charges at you constantly.
The Cameo: Appears at the beginning of Frost Walrus' stage in X4, frozen in the background.
Desperation Attack: Fires a Freeze Ray that traps X in ice.
Foil: To Frost Walrus, a Reploid boss of X4 who also has ice powers. To some degree, Walrus is the opposite of Buffalo: he was a violent Maverick even before the Great Repliforce War, while Blizzard Buffalo, even after being infected with the Maverick Virus, was a pacifist and was one of the few infected Mavericks to not directly harm humans. This comparison was even highlighted in the Rockman X4 manga.
Freeze Ray: His desperation attack has him fire out one, and if this hits X, it freezes him in place.
Gentle Giant: Before becoming infected by the virus, at least.
Harmless Freezing: If his ice beam gets you.
Heel–Face Turn: In the manga, he returns to his former self and joins the Maverick Hunters.
Horn Attack: Can use it to grab X and ram him into the wall.
Horned Humanoid: He is a buffalo robot and thus comes with the horns.
An Ice Buffalo: Attacks with ice balls and even an ice beam.
Impaled with Extreme Prejudice: In the X4 manga, Buffalo goes with X to confront Frost Walrus, who had been ruthlessly hunting Reploids for sport. Walrus swiftly defeats X, battering him so bad that it left him unconscious. Buffalo steps in to help and save X, and Walrus viciously kills Blizzard by impaling him with a giant icicle using the Frost Tower attack.
Logical Weakness: His weakness to the Parasitic Bomb may seem odd until you realize that buffalo in Real Life tend to be hounded by loads of parasites, and even need birds to clean them off. Also, explosives > ice.
Our Minotaurs Are Different: He is a humanoid buffalo Reploid.
Slippy-Slidey Ice World: His stage is set in a frozen residential area of Dopple Town.
Spikes of Doom: Frost Shield's uncharged attack can create ice spikes on the ground.
Stock Animal Behavior: Charging at you.
Taking the Bullet: Dies saving X from Frost Walrus' attack in the X4 manga.
Utility Weapon: Frost Shield has two very useful utility purposes: first, most types of enemy are guaranteed to drop a health pickup if killed with Frost Shield, making it by far the fastest way to fill up X's Sub Tanks. Second, charging up Frost Shield in the water will create a large ice block that X can stand on to float to the surface.
Warm-Up Boss: Because of his simplistic AI, he is a good first boss for those new to the game.

Crush Crawfish

Destruction God of the Seven Seas

"Hyahahahaha! This fella is an extraordinary sacrifice indeed!"

Japanese Name: Scissors Shrimper

A violent clawed lobster/shrimp-based Reploid. There was a programming error in his AI that prevented him from distinguishing between allies and enemies, and thus he attacked anyone indiscriminately. Due to his violent nature, he was sealed away in Doppler Town. During Dr. Doppler's uprising, however, he has now been let loose to wreak havoc in the shipyard.

Weapon: Spinning Blade

Weakness: Triad Thunder

Alliterative Name: Times two.
Ax-Crazy: An AI flaw made him unable to distinguish between allies and enemies, causing him to become violent.
Boom, Headshot!: In the manga, he is finally killed when X shot him in the head with a laser-like buster shot.
Deadly Disc: His Spinning Blade.
Desperation Attack: Performs a very painful bum rush if X is on the ground.
Giant Enemy Crab: A shrimp robot that is bigger than X and most certainly not a friendly character.
Graceful Loser: In the manga, a dying Crawfish was impressed with X's judgment as he had not withdrawn from the battle but rather found a place to kill him from a safe distance.
Hostage Situation: Does this in the manga after almost getting beaten by X.
Logical Weakness: Metallic blades are a good conductor of electricity. Additionally, for a saltwater maverick, electricity is very bad news.
Player-Guided Missile: Charged Spinning Blade fires a disc that can be moved around by the player, making it look like a yo-yo.
Power Pincers: His main method of attack is via his sharp, scissor-like claws.
Psycho for Hire: Due to a flaw in his AI that made him unable to tell an enemy from an ally, he was violent and leaned towards being a Maverick. He was locked up in a warehouse before he was released by Dr. Doppler.
Robotic Psychopath: Thanks to his AI flaw, he was already violent and psychopathic even before he joined Dr. Doppler — no Maverick Virus needed.
Ship Level: The later part of his stage is set inside a ship he's in. You later get to blow the ship's core, causing the stage to rotate 90 degrees.
Stock Animal Behavior: Pinching the player character with his huge claws. Painfully.
Spam Attack: What happens if he grabs you. Mash the buttons to get out quickly!
You Will Not Evade Me: Attempt to Wall Jump away from his deadly pincer move and he'll throw a net to get you back down.

Gravity Beetle

Steel Revenger

"I'll kill you... I'll kill you... I'll kill you, Mega Man X!"

Japanese Name: Gravity Beetbood

A rhinoceros beetle-based Reploid, Beetle is a former Maverick Hunter from the 17th Elite Unit. After the death of his brother Boomer Kuwanger, he wanted to avenge him and joined Dr. Doppler's forces in order to get a fight against X. He controls an airport that transports supplies for Doppler's army.

Weapon: Gravity Well/Bug Hole

Weakness: Ray Splasher

A.I. Breaker: Getting hit with Ray Splasher causes him to always make a short hop forward on recovery, letting him be hit again before he can attack.
Avenging the Villain: He tries to avenge Boomer Kuwanger from X1.
Big Creepy-Crawlies: He is a large rhinoceros beetle robot.
Desperation Attack: Summons a gigantic black hole into the air, and will then try to throw X into it.
Easily Forgiven: Since his only reason for going Maverick is to get revenge on X over Kuwanger's death, he was pardoned for his actions by X and Zero in the X3 manga.
Gravity Master: Throws gravity balls that bounce around, growing larger, and dealing huge damage to X when they're large. His Desperation Attack has him summon a huge black hole in the air making X's jumping higher, but will also damage him by a good bit on contact.
Horn Attack: Can charge into X and throw him into the air, similar to Boomer Kuwanger. It gets more dangerous during his Desperation Attack where he'll throw X into the black hole he summons.
Horned Humanoid: Being a rhinoceros beetle robot, he comes with the horn and all.
Hyper-Destructive Bouncing Ball: His gravity balls bounce around the room, growing larger and more painful as they bounce.
Logical Weakness: Light is far less affected by gravity compared to physical substances thanks to having little to no mass.
Japanese Beetle Brothers: With Boomer Kuwanger.
Red Oni, Blue Oni: The Red to Boomer Kuwanger's Blue. Where Kuwanger acts on logic and fights uses a more tactical style with teleportation, Gravity Beetle stomps around, throws gravity balls, dashes at X, and tries to throw X into the ceiling using his horn.
Spared by the Adaptation: After X and Zero thwarted his plan to resurrect Kuwanger in the manga.
Stock Animal Behavior: Throwing player with his horn.
Tough Beetles: He is based on the rhinoceros beetle, and, besides his gravity balls, possesses enough strength to effortlessly throw X into the air with his Horn Attack.
Unrealistic Black Hole: His Desperation Attack.
Utility Weapon: Charging up Gravity Well can raise certain objects that act as a lift for X.
You Killed My Father: His main motivation for joining Doppler to fight X.

Neon Tiger

Guardian Deity of the Jungle

"I won't let you escape!"

Japanese Name: Shining Tigerd

A tiger-based Reploid and poacher hunter designed to ensure no one attempted to steal or harm the remaining natural wildlife. Unfortunately, he went Maverick after being infected with the Maverick Virus and now prowls the massive artificial forests surrounding Dopple Town. Utilizing solar energy as a power source, his power is said to be unlimited as long as there is available sunlight.

Weapon: Ray Splasher

Weakness: Spinning Blade

A.I. Breaker: In a downplayed example relative to many bosses, Tiger defends himself whenever X fires a charged shot at him, which also triggers his Desperation Attack later in the fight. The cross-charged shot from the Arm Parts found in his stage, however, pauses in midair when the shots combine, with the result that Tiger instead drops his guard right before it smacks him in the face.
Desperation Attack: He turns orange and invulnerable, then charges at X and does a leap-slash. Quickly jump up the wall and over him to avoid this.
Fangs Are Evil: He used to be good, but still.
Jungle Japes: His stage is set in a nature reserve.
Laser Blade: He has laser claws.
The Law of Diminishing Defensive Effort: He isn't bothered to block weak uncharged shots, but will use his claws to guard against anything stronger.
Light 'em Up: Attacks with light-based energy and is powered by solar energy.
Light Is Not Good: Despite having light-based weaponry, he is still a dangerous Maverick.
Logical Weakness: Neon Tiger's Wall Crawl tactics won't do much good against a razor-sharp cutter that arcs upward to hit while he can't defend, due to his claws holding him onto the walls.
Multi-Directional Barrage: Charged Ray Splasher shoots out a light sphere upward which will then spread light shots to random directions.
Panthera Awesome: A Maverick based on a tiger and a pretty tough combatant.
Parrying Bullets: His laser claws can parry fully charged X-Buster shots.
Spread Shot: His Ray Splasher is a Spray Burst.
Stock Animal Behavior: Pouncing down on player from a wall cling.
Unusual Weapon Mounting: He fires his Ray Splasher from his tail.
Wall Jump: He uses his claws to leap from wall to wall.
Wolverine Claws: His claws are in two pairs of three Laser Blades.

Toxic Seahorse

Water Dragon President

"In this silent land, where time has brought to a halt... inviting someone to fight is too rough... as if they were to summon a devil... then I, Toxic Seahorse, shall sink you to the bottom of the sea forever!"

Japanese Name: Acid Seaforce

A spiny seahorse-based Reploid of unknown origin. He has taken control of Dopple Town's major dam and water resevoir, obstructing it in order to restrict the supply of drinking water for the humans.

Weapon: Acid Burst/Acid Rush

Weakness: Frost Shield

Acid Attack: He fires acid balls that splash on contact with walls. Later on, he fires bouncy acid balls as well, and acid does not work that way in real life.
A.I. Breaker: Getting hit by Frost Shield always makes him jump in response, usually right onto the next Frost Shield.
Blob Monster: He's made of liquid metal, which allows limited shapeshifting.
Desperation Attack: Fires out two strong, hard-to-destroy bouncing balls of acid.
Down the Drain: His stage is set in a dam.
Elemental Shapeshifter: Thanks to being made of liquid metal, he can shapeshift into an acid-like substance and back. However, this also makes him vulnerable to freezing.
Fish People: Being a seahorse robot, he fits like one.
Logical Weakness: Acid is still a liquid, so it can be frozen with an ice weapon. Due to being made of liquid metal, he would also freeze very easily. Seahorse Popsicle is the result.
Seahorses Are Dragons: He is at least called a "dragon" in his nickname.
Spread Shot: The Acid Burst will splash smaller shots out when it hits a wall.
Together in Death: In the X3 manga, when X and Zero chase after him, they see he has escaped to the top of a tree and is quietly hugging a frozen, female Reploid, who was his girlfriend. Seahorse is also about to liquefy his programming, which would kill him. X wants to stop him and take him into custody, but Zero convinces him not to, saying they have finished their task of defeating Seahorse and fixing the dam he ruined. Seahorse then expires, together in death with his beloved.
Narrator: It was then when X remembered. Seahorse had called his dam his "holy ground" and he had said that "he was already dead"...but there was no way X could have understood the true meaning of those words. The honorable dam recovered its original function again. The ruins fell into a silent sleep. And Seahorse too became unknown...The metal liquid gently embracing the Reploid who stands still.
Utility Weapon: Acid Burst will cause nearly all enemies to drop weapon energy pickups, although X will need to switch weapons to refill anything except Acid Burst itself.
Warrior Poet: Talks like this in the X3 manga.

Tunnel Rhino

Barbarian of the Earth's Depths

"You're not going to Master Doppler!"

Japanese Name: Screw Masaider

A rhinoceros-based Reploid, Rhino was formerly an Energen crystal miner who became a Maverick after being invited to Dopple Town. Under Doppler's orders, Rhino occupies a rock quarry and uses his weapon, Tornado Fang, for both mining and to cause chaos.

Weapon: Tornado Fang

Weakness: Acid Burst/Acid Rush

Abandoned Mine: Like Armored Armadillo, his stage is set in a mine.
Bullfight Boss: He charges at you, then drills into the rock.
Desperation Attack: Performs a damaging, invincible charge attack.
Fast Tunnelling: Does this in his Boss Subtitles animation for the PC and Playstation ports.
Foe-Tossing Charge: His charge when at low HP will toss X across the room.
Horned Humanoid: Being a Rhinoceros robot, he comes with the horns.
Invulnerable Attack: When his life gets low, he gains a charge move where he cannot be damaged.
Logical Weakness: Acid can dissolve metals. In this case, drills and heavy machinery get damaged by corrosion.
Rhino Rampage: A Rhinoceros Maverick who attacks by charging at X.
Shoulders of Doom: Which he can actually fire out drills from.
Smarter Than You Look: If X jumps over Rhino too early, he'll actually brake to a stop instead of continuing to charge, or try to fake X out by firing his shoulder drills upward. This behavior is notable due to being directly comparable against Blizzard Buffalo, who has the same basic attack pattern as Tunnel Rhino but employs neither of these countermeasures.
Stock Animal Behavior: Modeled after the rhinoceros, he's obsessed with charging at the player.
This Is a Drill: His main weapon is the Tornado Fang, a drill that spreads into three attacks.
Utility Weapon: The Tornado Fang can be used to drill through certain unbreakable walls.
Warm-Up Boss: Another simple-to-fight boss with some practice at wall jumping to avoid his charges. Tornado Fang is required to collect some upgrades, so this Maverick is an excellent first pick to minimize backtracking.

Volt Catfish

Rescue Power Plant

"I'm getting so excited~! The smile of superconductivity, Volt Catfish, at your service!"

Japanese Name: Electro Namazuros

A playful electric catfish-based Reploid. Acting as an emergency power source for cities during blackouts, he has an incredible generator built into his body, making him a veritable walking power plant. However, after being invited to Dopple Town he was made a Maverick. He has hijacked Dopple Town's main power plant and now siphons its energy to Dr. Doppler's research facility.

Weapon: Triad Thunder

Weakness: Tornado Fang

A.I. Breaker: Tornado Fang makes him always respond by jumping onto X, unless he's trying to start his Desperation Attack in which case he'll jump in place in the center.
Attack Drone: Triad Thunder creates 3 drones that shoots electricity.
The Catfish: Albeit a humanoid electric catfish.
Desperation Attack: Turns invulnerable and sprays sparks all over, then tries to rush you.
Eternal Engine: Like Spark Mandrill, his stage is set in a power plant that he tries to take electric power from.
Heroic Sacrifice: In the manga, after being defeated by X, Volt Catfish used his body as a replacement generator to return the electricity he stole, at the cost of his life.
Invulnerable Attack: During his Desperation Attack, Catfish is invincible to every attack save for the Tornado Fang.
Logical Weakness: Catfish burrow in the mud, which would be easily disrupted by drills. A drilling attack also breaks his shields in the second phase.
Manchild: In his "intro video" (Playstation version only) he is shown sliding out of a water slide, smiling widely.
Psycho Electric Eel: He is based off an electric catfish.
Shock and Awe: Like his name suggests, he attacks with several electrical attacks.
Utility Weapon: Charging up his Triad Thunder will allow X to use a Ground Pound, destroying certain background objects.

Mega Man X4

General

Boss Banter: They usually do this every time they showed up. Most of them were cut in the English version, however. The trend would later continue from X6 onwards.
Not Brainwashed:
- The bosses of Repliforce were not infected and brainwashed by the Sigma Virus, only becoming Maverick due to Just Following Orders from superiors that were branded Maverick, although some such as Frost Walrus had very questionable behavior before they joined, while others committed atrocities after the war kicked off.
- Even of the Mavericks that are under Sigma's employ in this game, only Cyber Peacock and Split Mushroom were explicitly corrupted by the Sigma Virus. Magma Dragoon and Split Mushroom joined Sigma of their own free will, the former to have his fight to the death with X and Zero, and the latter seemingly out of gratitude for Sigma bringing him back after his "retirement". And then there's Double, who's an enigma all of his own that's suggested to have joined Sigma for fun and killing.

Cyber Peacock

Network Guardian

"You’re really something, aren’t you? Making it all the way here. But you cannot win against me! Prepare yourself!"

Japanese Name: Cyber Kujacker

A digitized peafowl-based Maverick. Peacock was originally an AI that protected the network from hackers before he was corrupted by Sigma. He then begins corrupting the network himself, to draw the Maverick Hunters attention as he was tasked to measure their capabilities.

Weapon: Aiming Laser/Rakuhouha

Weakness: Soul Body/Ryuenjin

Voiced by: Issei Futamata (JP)

Agent Peacock: Quite literally. He is a pretty elegant fellow in combat.
Cyber Peacock: "Here I come!"^note"Iku wa yo!"
A.I. Is a Crapshoot: Justified, as Peacock's programming was rewritten by Sigma.
Camp Gay: In the Japanese version, he is this to a T and speaks like an effeminate gay man. He ended some of his phrases with "わね" (wa ne) and "わよ" (wa yo), both of which are feminine ending structures used by women to express exclamation or confirmation. Furthermore, Peacock addressed himself with the pronoun "あたし" (atashi) which is an exclusively feminine way of referring to oneself. He shouts "ひどいわ！！" (Hidoi wa!!, How cruel!!) when hit with his weakness, pronouncing "wa" with a rising intonation that marks it as feminine.
- This is Lost in Translation in the English version due to the language's lack of gender-identifying first-person pronouuns as well as Peacock's voice lines being removed, with no indication he speaks effeminately.
The Cracker: A hacker AI maverick skilled at corrupting networks.
Crosshair Aware:
- During his Desperation Attack he'll put a crosshair on the player and then he'll be constantly targeted by homing tail feathers.
- When X acquires his weapon, it comes with a crosshair that can target enemies on a half circle (180 degrees) in front of him; after locking to up to 3 enemies, he can then fire a continuous laser at them.
Cyberspace: His stage is set in one. The first half consists of 3 "trials" where the player have to move forward to the "finish lines" as quickly as possible; if the player get the S rank, they will get rewards, i.e the Heart Container, the E-Subtank and Dr. Light's capsule. Along the way X/Zero find yellow cyber-balls that will slow them down and are indestructible (except for Split Mushroom's weapon). The second half is in the deeper part of the cyberspace where there are buttons that change the layout of the level, turning things upside down.
Desperation Attack: Fires his tail feathers at the player.
Digitized Hacker: He is an AI who is able to hack networks.
Feathered Fiend: A Peacock maverick and a skilled hacker of a villain.
Feather Flechettes: Homing exploding feathers projectile.
Homing Projectile: When low on health he'll lock onto the player character and fire exploding feathers that home in on them. Unfortunately, these are not destructible.
Cyber Peacock: "You cannot escape!"^note"Nigasanai wa yo!"
Taking You with Me: He tried this in the manga version of X4. When Zero enters the cyber network with his own A.I. to destroy the corrupt presence that has infected it with malicious bugs, he realizes that Peacock is the one who is causing the damage. After destroying many of the bugs in the virtual network, Peacock uses his powers to make Zero hallucinate and relive past memories, particularly memories he had forgotten, of his past as a Maverick. After a brief fight with Peacock having the upper hand, Zero gets serious and easily destroys Peacock's Tracking Shot feather attacks, and slashes him, causing serious injury. Zero says he doesn't need to worry about a forgotten past, nor an unforeseen future, only the present. Peacock then does a "suicide bomb" attack, erasing himself and then spreading the erasure to the entire network in an attempt to permanently trap Zero in the virtual world. However, Zero is able to escape just in the nick of time.
Logical Weakness:
- Thanks to holographic projections not being "real", it disrupts his analysis and his code's structural integrity. Also, having duplicate objects can really mess up a poorly-optimized code.
- For Zero, his weakness to Ryuenjin has another explanation — firewalls are effective at blocking viruses and hackers.
Peacock Girl: Even though Peacock is a male, he acts a little effeminate.
Power Floats: Floats around the room during most of his attacks.
Spread Shot: Zero's weapon, as his Giga Attack that covers the whole screen.
Stock Animal Behavior: Expanding his tail feathers to attack you.
Teleport Spam: His main movement is via teleporting, usually on top of X or Zero to do Collision Damage.
This Cannot Be!: His response to X's potential being "limitless".
Cyber Peacock: "His potential ability... is immeasurable!? Unbelievable."
X: "Who are you? Why would you do such a thing?"
Cyber Peacock: "I was asked to by a certain someone. To investigate you, he said."
X: "What!?"
Cyber Peacock: "Well then, here I come!"
Weaponized Teleportation: Has a very huge tendency to teleport on X's or Zero's position to deal Collision Damage.
Years Too Early: His intro Boss Banter in the Japanese version.
Cyber Peacock: "You're ten years too early to pick me as your opponent."

Frost Walrus

Arctic Rumbler

"I must have been taken lightly, for my opponent to be such a kid. Whatever, I’ll tear you apart!"

Japanese Name: Frost Kibatodos

A walrus/Steller sea lion-based Reploid. Frost Walrus was a Reploid whose ill-tempered and destructive behavior got him labelled Maverick, but he was saved when General invited him to join Repliforce. As a Repliforce member, Walrus was under the impression that chaos was a military man's duty. When the war between Repliforce and the Maverick Hunters broke out, Walrus was excited for the coup d'etat and got put in charge of guarding a snowy Repliforce base developing secret weapons.

Weapon: Frost Tower/Hyouretsuzan

Weakness: Rising Fire/Ryuenjin

Voiced by: Kazuo Oka (JP)

Adaptational Badass: In the manga version of X4, Walrus is able to easily take on both X and Blizzard Buffalo at the same time in battle with his physical strength and ice powers. Near the end of the fight when X leaps up to perform a Buster Shot against Walrus, he notices in shock that there are no footprints around Walrus, meaning he has knocking X and Buffalo around the entire fight without moving a single step. Walrus then ruthlessly impales X on his ice shoulder blade, wounding X so badly that he loses consciousness. Buffalo steps in to fight Walrus himself, and when X wakes up, he finds Buffalo killed, impaled by a large icicle attack from Walrus. X then tracks down Walrus's base and confronts him again, this time prepared with Ride Armor. Walrus is able to swiftly destroy the Ride Armor with his Frost Tower attack with little effort, but X damages him heavily by setting him alight with the fuel tank of the broken Ride Armor...and Frost still gains the upper hand on X. Before he can kill him, though, he is brutally shot down by General for his previous misconduct and to save X's life. Compare that juggernaut to the game version, who is considered a Warm-Up Boss of the game by a good majority of players and can be shredded easily even without his weakness due to how slow and big he is.
Adaptational Villainy: His outrageous behavior is very much amplified in the Rockman X4 manga. During the Repliforce rebellion, he keeps a base called the "Fierce Man's Room" (猛者の間), and causes riots where he slaughters lots of Reploids for fun. In his base, Walrus keeps the bodies of his victims who managed to survive more than 20 seconds of his hunting as a "reward" for their endurance and as trophies for himself. This eventually causes him to be rebuked by the Colonel, who says he will report Walrus to the General and tells him to stop causing wanton destruction. And what does he do next? He throws a temper tantrum, slams the ground, and decides to do the same thing he was warned to stop doing. He releases dozens of Reploid prisoners he has kept in the base and proceeds to slaughter them all one by one, with one Reploid being saved by the timely intervention of Hunters X and Blizzard Buffalo. Walrus's strength is too much for them, and he knocks X out while ruthlessly impaling Buffalo with a Frost Tower. When X comes to fight him again at his base, the Hunter destroys several of the ice cases of Reploid bodies in Walrus's base, infuriating him. Walrus is then heavily injured by X destroying the fuel tank of a Ride Armor, but he still recovers and gains the upper hand. General then brutally shoots him down and kills him to save X's life, and as punishment for his previous sociopathic behavior.
Badass Boast: In the Japanese version, with one of his pre-battle lines.
Frost Walrus: I'll put ya to sleep in a bed of ice!^note"Kōri no beddo de o nen'ne-shina!"
Big "YES!": In the Japanese version, he would say "Oh yeah!" ( よっしゃ, Yossha!) while doing the Frost Tower attack.
Blood Knight: He was very angry and destructive before joining Repliforce. Indeed, his destructive nature got him marked for termination as a Maverick, but before he could be punished, the General did him a favor and saved him by inviting him to join Repliforce. This is something Colonel reminded Walrus of when he rebuked him in the X4 manga for causing riots unrelated and unhelpful to the Repliforce's coup plans.
Desperation Attack: Creates a giant ice crystal that falls to the ground and explodes into a rain of icicles.
Elemental Barrier: X can use his weapon like this. It can also be dropped from above if done in midair.
Fangs Are Evil: One of the more evil members of Repliforce and being a Wily Walrus, he's got the fangs. Made of ice, no less.
Fat Bastard: Big and likes to look down on others weaker than him. Especially in the manga.
Hunting the Most Dangerous Game: In the X4 manga, after Colonel comes to his headquarters and berates him for causing unnecessary riots unhelpful to the Repliforce's coup d'etat, he goes on a tantrum and releases dozens of Reploid prisoners and tells them to run as fast as they can. He later hunts them down and brutally kills all of them, save one, who was saved by X and Blizzard Buffalo.
Just a Kid: Says this before confronting X/Zero, which is ironic since the two are the oldest Reploids in existence.
Frost Walrus: "I must have been taken lightly, for my opponent to be such a kid. Whatever, I’ll tear you apart!"
- Zero takes offense at this.
  Frost Walrus: "I wondered what sort of guy would come, and it’s just some blonde kid! I can’t go all out like this!"
  Zero: "I’ll make sure that big mouth will never run off again."
  Frost Walrus: "W-What!? Damn brat, I'll smash you flat!"
- His intro dialogue against Zero in the English version is even more straightforward.
  Frost Walrus: "What's that blonde kid up to?! I don't have time for you junior!"
  Zero: "Hey! Shut up and fight me already!"
  Frost Walrus: "Oh... that does it, you're goin' down!"
Large and in Charge: Of his Repliforce weapons warehouse.
Logical Weakness: Like a lot of Ice-based bosses, he is weak against a fire-based weapon. Walrus On Fire is the result.
Mighty Glacier: Big and slow, but his ice attacks pack a wallop. Along with him having ice powers, he's a Mighty Glacier in every sense of the word.
Monstrosity Equals Weakness: He is the one of the biggest Mavericks in the series (only eclipsed by Rainy Turtloid in X6), but is pretty easy.
Prepare to Die: Only in the Japanese version as one of his intro Boss Banters.
Frost Walrus: I'll crush you! Get ready!
Shoulders of Doom: Has big round shoulders adorned with icicles.
Slide Attack: Slides on his belly to rush at you. He may sometimes jump first and then fall belly-first before doing so if you're in midair (anticipating your evading attempt).
Slippy-Slidey Ice World: The first half of his stage is set in an icy mountain with lots of snowy winds, and the second half is set in a base in the said mountain which houses frozen robots.
Smart Bomb: Charged Frost Tower summons a lot of big falling ice chunks that can potentially fill the whole screen.
Sociopathic Soldier: He was already dangerously sociopathic before joining the Repliforce.
Stock Animal Behavior: Slides around as a walrus would.
Sword Plant: Zero's acquired move, used with a big icicle.
Villainous Glutton: Is shown in the Manga gorging on tubs of Vanilla Ice Cream
Weak to Fire: As an ice-based boss, he doesn't take too well to Rising Fire or Ryuenjin, taking extra damage and even catching fire when hit by them.
Wily Walrus: A gigantic walrus who looks down on the weak and loves rampaging around.

Jet Stingray

Aqua Destroyer

"Hmph. I can’t believe I've been followed... but this is as far as it goes. Here I come, X!"

Japanese Name: Jet Stingren

A stingray-based Reploid and member of the Repliforce Navy. Jet Stingray is a dutiful soldier who has worked his way up the ranks to become an invaluable asset, and has great respect for both General and Colonel. During the Great Repliforce War, Stingray attacked a city's underground power station to draw the Maverick Hunters' attention.

Weapon: Ground Hunter/Hienkyaku

Weakness: Frost Tower/Hyouretsuzan

Voiced by: Osamu Hosoi (JP)

Adaptational Heroism: In the game, he is arguably Repliforce's biggest war criminal during the coup, having decimated a city. In the Manga, he evacuated the population beforehand and genuinely cared for the soldiers under his command.
Airborne Mook: He is able to fly, as well as move underwater unimpeded.
Arm Cannon: Used for the Weapons That Suck below.
Attack Drone: The Ground Hunter.
Authority Equals Asskicking: A high-ranking member of the Repliforce Navy and a powerful combatant in his own right.
Auto-Scrolling Level: Both parts of the level have you speeding on a Ride Chaser that automatically goes forward. Getting squished by the obstacles and the left edge of the screen will kill you.
Badass Boast: Says this to X/Zero as one of his intro Boss Banters. This is exclusive to the Japanese release.
Jet Stingray: "Farewell. Disappear alongside the ocean's algae waste!"^note
Cruel Mercy: In the manga adaptation, while he evacuated the city before he destroyed it, he still caused a massive refugee crisis. Zero notes that many will die without the vital infrastructure the city provided.
Desperation Attack: Two of them. The first has him suck you near him with a whirlpool, and charges at you if you get too close. The second has him fly offscreen, then fly vertically into you from top and bottom.
A Father to His Men: In the X4 manga, Stingray clearly cares about his subordinates serving under him, telling them to withdraw and retreat so he can fight Zero alone, who came to confront Stingray after he blew up a city power plant as a diversion. When Stingray and Zero are nearing the end of their battle, his men interrupt them, having ridden in with Ride Chasers to help their boss. Before they can, though, they (and Stingray) are all blasted in a surprise attack from the Reploid Self-Defense Forces, who had come to stop Repliforce's coup. Stingray is clearly anguished overseeing his men blasted to oblivion, and he laments their deaths before succumbing to his own wounds from the blasts and perishing as well.
Fish People: He is a stingray robot, which technically still counts since stingrays are fish.
Flying Seafood Special: A flying stingray Reploid.
Flunky Boss: He sends out his Ground Hunter stingray drones to harass X or Zero.
"Get Back Here!" Boss: The second half of the level is spent trying to stop him while you ride on the Ride Chaser.
Hidden Depths: X4's manga adaptation shows him destroying a city mentioned above. He also had his Repliforce troops evacuate the city of humans beforehand, which was not mentioned in the game. Jet is clearly saddened at the destruction, making it a case of I Did What I Had to Do.
Hero-Worshipper: The manga reveals that the Colonel once saved Stingray's life by taking a blast meant for him during a Repliforce mission, which made Stingray have the utmost respect for him. It also formed the core of his Undying Loyalty to General and Colonel, as he views them both as the standard by which he set himself as a career military fighter.
Increasingly Lethal Enemy: If his Ground Hunter drones aren't destroyed, they'll collect on the arena floor and swarm back and forth. If you're not careful or fast enough, X and Zero will get shredded by a few dozen of them running around on the arena floor.
Land, Sea, Sky: Representing Sea with the Repliforce Navy.
Leg Cannon: He apparently shoots his Ground Hunter from his leg.
Logical Weakness: He likes being in the water and thus he gets frozen easily. Also, the Frost Tower literally creates a large, tough block of ice, which naturally presents a problem to someone who attacks by launching themselves around at a high speed.
Making a Splash: His whirlpool attack.
Player-Guided Missile: Ground Hunter can be commanded to fall down quickly to the ground after being fired. Charged version is a variant: by pressing up or down as it goes, the enhanced projectile can fire smaller Ground Hunters up or down.
Ramming Always Works: Several of his attacks consist of charging at X or Zero.
Sinister Stingrays: Commits Repliforce's biggest war crime in the game.
Undying Loyalty: Jet Stingray had great respect for both General and Colonel, so when General announced his move for Reploid independence, there was no question as to where his loyalties lay.
[Verb] This!: He says "Koredemo Kurae!" (Eat this!) when firing robotic stingrays at his opponent, in the Japanese version.
Videogame Dashing: Zero's acquired "technique" is a mid-air dash similar to Stingray's flying dashes.
Waterfront Boss Battle: X/Zero are underwater, however, most of the time Stingray is above the surface.
Weapons That Suck: He can use the jet turbine on his right arm to pull X or Zero towards him.

Magma Dragoon

Martial Artist of Exploding Flame

"That’s right! Get mad, X! Show me your true power!"

Japanese Name: Magmard Dragoon

A dragon-based Reploid, former member of the Maverick Hunters' 14th Special Unit, he betrayed them and bombed the Sky Lagoon for a chance to duel with X and Zero. Under the promise of obtaining what he desired most, he has loyally followed Sigma's orders and now awaits the inevitable confrontation with the Hunters in a volcano.

Weapon: Rising Fire/Ryuenjin

Weakness: Double Cyclone/Raijingeki

Voiced by: Takashi Nagasako (JP)

Adaptational Heroism: In the manga, he doesn't drop the Sky Lagoon and kill thousands of innocent people to goad X/Zero into fighting him, instead challenging X directly after X kills Storm Owl.
Big Ol' Eyebrows: His ridge has the appearance of these.
Blood Knight: He destroyed the Sky Lagoon, killing thousands of innocent people and indirectly kicking off the war with Repliforce in the process, all for a chance to face X and Zero in combat. If that doesn't qualify, nothing does.
Breath Weapon: His Rising Fire lodged in his mouth, which fires a stream of fireballs from his mouth.
The Cameo: A digitized, toned down version appears as the Training Mode boss in X5.
Calling Your Attacks: Whenever he uses Hadoken or Shoryuken, he'll call out "Hadoken!" and "Shoryuken!" respectively.
Death Equals Redemption: Zig-Zagged. His Final Speech invoked this, but he was still rebuilt in the Final Weapon and once again fights X/Zero (though given the entry for Came Back Wrong, what you're fighting is probably just a shell).
Death from Above: His Desperation Attack is firing many fireballs to the sky and then they fall down like meteors.
Diving Kick: Uses one covered in the fire to attack X or Zero. It's based on Akuma's Tenmakujinkyaku.
Double Reverse Quadruple Agent: He started off as a Maverick Hunter, framed then joined Repliforce as part of his overall ploy to get X/Zero to fight him, was aligned with Sigma, but in the end was only in it for himself.
Draconic Humanoid: A humanoid dragon Reploid.
Expy: He serves as one for Akuma. Both of them have a Blood Knight nature, have necklaces of large beads around their necks, have "Heavenly Sky" symbols, and perform similar attacks such as the Hadoken, Shoryuken, Tenmakujinkyaku, and Tenma Gou Zankuu. The manga adaptation of X4 even has him adopt some of Akuma's personality traits, uses one of trademark poses as a fighting stance, and TEPPEN even makes the direct comparison with a card depicting him fighting Akuma himself.
Evil Sounds Raspy: His voice is really raspy, and is an evil Maverick who destroyed the Sky Lagoon to betray the Maverick Hunters.
Face–Heel Turn: As mentioned, he was a member of the 14th Special Unit before Sigma offered him to destroy the Sky Lagoon and betray the Hunters.
Fallen Hero: Was once a Maverick Hunter until Sigma showed up gave him an offer he can't simply refuse.
False Friend: When X/Zero first meets him, he frantically tells them the Sky Lagoon's systems have been destroyed and they need to get out while they still can. Sounds nice of him...until he gleefully reveals later that not only was he the one who destroyed said systems (in fact, the way it's framed seems to indicate they reached just as he was finishing up) but the entire reason he wanted them out was that otherwise he wouldn't get his reward for doing so if they died in the crashing.
Final Speech: Notable for being the only standard-8-animals-Maverick boss to have one.
Fireballs: He can create one, then throw it into the magma pool of the sides of his arena to create a geyser of lava. This also conveniently can prevent you from (at least as X) unleashing Charge Shots while using Wall Jump on the side of his arena to avoid getting pummeled in close quarters.
Half the Man He Used to Be: During his Final Speech, only his upper body remains intact. It quickly goes with the rest of him once he says his piece.
Kamehame Hadouken: Attacks with fiery Hadokens, high and low.
Lethal Lava Land: He hides in a volcano, and you have to chase him there.
Lava Pit: His battlefield is a small island surrounded by lava on both sides.
Lightning Bruiser: Strong, tough, and fast enough to deliver heavy-hitting Spam Attacks!
Logical Weakness:
- Wind blows away fire.
- All of that martial arts prowess isn't going to be as helpful if his opponent brings an armored vehicle to the duel.
The Mole: It's not clear for how long he was being influenced by Sigma, but it was definitely before the fateful events of the Sky Lagoon incident.
Ninja Pirate Zombie Robot: A martial artist robot dragon.
Not Brainwashed: Possibly. We're never told if Sigma infected him with the Sigma Virus, or whether he was just manipulated by Sigma appealing to his Blood Knight nature.
An Offer You Can't Refuse: He was offered a chance to fight X and Zero in exchange for blowing up the Sky Lagoon. Guess who made the offer.
The Only One Allowed to Defeat You: Says this word for word against X/Zero before the boss fight in the Japanese version.
Magma Dragoon: "This time, I'll triumph over you!"
Our Dragons Are Different: Here, we have a martial artist robot who betrayed his teammates out of sheer desire to fight.
Playing with Fire: Fights exclusively with fire-based attacks. Even all his martial arts moves have flames covered on them! Ties into Magma Man with the aforementioned lava geyser attack.
Promoted to Playable: He was added as a playable character in DiVE on January 20th, 2021, making him the first of these Maverick bosses to be made into a playable character, and the first and only animal-themed reploid to become a playable character at present.
Rewarded as a Traitor Deserves: Betrayed the Maverick/Irregular Hunters and the game itself heavily enforces the player to fight him first (due to the Ride Armor and the fact that his weapons are useful). Further, he's even made into a training dummy in X5.
The Social Darwinist: One of his intro Boss Banters in the Japanese version implies that he believes in this.
Magma Dragoon: "Power is everything!"
Shoryuken: One of his moves, which can knock you off the wall easily if you tried to cling to it to avoid his attacks. Zero's Ryuenjin is based on this. X's charged Rising Fire also becomes this.
Shotoclone: And a pretty blatant one at that, as he is an expy of Akuma and can use a lot of his moves, including the Hadouken and Shoryuken, complete with the same attack motions and attack name calls. Defeating him gives Zero a Shoryuken-style move and X a fireball that shoots upwards, but if charged is a proper Shoryuken.
Utility Weapon: Rising Fire/Ryuenjin can burn down wood and ice, allowing the player to uncover Heart Tanks.
Warm-Up Boss: X and Zero can enter the fight in a Ride Armor, which severely limits his challenge. This does not apply to the rematch against him at the end of the game, but by then the player definitely has his weakness.
Worth It: If playing as X, his Final Speech has him tell X that the evil he committed to incite the fight (and subsequent death) "was worth it... for a final duel..."

Slash Beast

Steel King of Destruction

"You’re quite the lively one, attacking my unit. Looks like I can have some fun for the first time in a while!"

Japanese Name: Slash Beastleo

A lion-based Reploid and the captain of the Reploid Army. He enlisted in Repliforce only to freely exercise his combat abilities, and shows dauntless courage in battle. During the coup, Slash Beast was put in charge of supervising and protecting Repliforce's military supply trains.

Weapon: Twin Slasher/Shippuuga

Weakness: Ground Hunter/Raijingeki

Voiced by: Takashi Nagasako (JP)

Ain't Too Proud to Beg: In the X4 manga, Beast is confronted by X in his train headquarters during the Repliforce coup d'etat. He charges confidently at X to attack, who has just received an upgrade with the Ultimate Armor. The next time we see him, he has been utterly blown to smithereens, and according to X, begged for his life before his death.
Authority Equals Asskicking: Slash is in charge of the unit protecting Repliforce's supply train, and is a far better fighter than the rest of his unit.
Bait-and-Switch: Once X/Zero arrives at the last train car, there's a giant crate in front of them while several more drop down behind them to prevent escape. What's the point of the single crate? Nothing but a target for Beast's Dynamic Entry.
Bad Boss: In the X4 manga, Beast savagely kills one of his Repliforce underlings in anger after he reported to Beast that one of their trains had been lost to the Maverick Hunters, one of whom was stronger than they thought, referring to Zero.
Blood Knight: Slash enlisted in Repliforce only to freely exercise his combat ability. In the Japanese version, he even says something like this before the boss fight.
Slash Beast: "Hey, kid! I hope you'll entertain me for a while!"
Slash Beast: "I'm so happy! It's been a while since the last time I fought!"
Boisterous Bruiser: He excels in combat techniques, and is proud of his abilities.
Counter-Attack: When his health is below half, he can sometimes prepare a special stance; attack him and he'll retaliate with the Twin Slasher.
Deadly Lunge: Has a powerful lunging attack that goes back and forth that he uses once his health go below half. Zero's Shippuuga is based on this. Also, see Desperation Attack below.
Desperation Attack: Two of them. The first is the above-mentioned Counter-Attack. The second one has him lunge at X/Zero, if this connects, he then grabs the player and smashes them into the wall.
Death from Above: Has a stomping attack after jumping high.
Dynamic Entry: He shows up Racing the Train X/Zero is on, jumping up and then destroying the crate in front of them upon landing.
King of Beasts: He is a lion-based Reploid in charge of a military unit.
Land, Sea, Sky: Representing Land (Repliforce's Army).
Lightning Bruiser: His attacks hurt if you're hit and are also fast enough to catch up with a train.
Locomotive Level: His stage is set on his military train that is carrying supplies.
Logical Weakness: A fighter who is fast on his feet will get tripped by a ground projectile; he probably won't see it coming.
Lost in Translation: He is a lion, but the English version cutting the "Leo" out of his name makes him an Ambiguous Species instead.
Racing the Train: His battle intro when you first fight him.
Razor Wind: His flash kick causes waves of energy to be shot out.
Roar Before Attacking: Tends to do this often before executing an attack.
Shout-Out: Uses a move similar to Guile's Flash kick.
See You in Hell: In the Japanese version of X4, this is one of Beast's pre-battle quotes.
Slash Beast: "I'll send you to Hell on the super express!"
Spread Shot: Twin Slasher is shot out in 2 directions. If charged, it fires 8 shots that cover a wider area.
Stock Animal Behavior: Roaring before attacking. Also, his desperation attack has him grab the player in his mouth.
Utility Weapon: A charged Twin Slasher is the only way to remove the blocks in front of the Body Armor capsule.
Wolverine Claws: Uses them as a Desperation Attack. It can be shattered by Ground Hunter, robbing him of most of his moves.

Split Mushroom

Little Devil of the Ruins

"Take a wild guess."

A playful mushroom-based Reploid, Split Mushroom was once an administrator of a Bio Laboratory who was decomissioned upon the lab's closure. During the Great Repliforce War, Mushroom was awoken by Sigma to aid the Repliforce in their coup by reactivating the abandoned lab as a fortress, attacking anyone who strayed too close.

Weapon: Soul Body/Kuuenbu and Kuuenzan

Weakness: Lightning Web/Raijingeki

Voiced by: Mari Maruta (JP)

Abandoned Laboratory: He sets up base in the decommissioned ruins of a laboratory, filled with traps and multiple robotic plants.
Absurdly Long Stairway: There are two grand spiral stairways serving as liminal spaces that signify the transition to the next phase of the stage. Each stairway seems to continue on indefinitely but you eventually find a teleporter pad to leave.
Desperation Attack: Does a head slam into the ground and releases deadly spores.
Doppelgänger Attack: He can create a fully-similar clone of himself (as opposed to a Hard Light) that he'll use to confuse the player. X's charged Soul Body does a similar thing, only that it creates an unarmored X that moves independently (but restricted to the screen) while the real X is invincible (but immovable) the whole time.
Hard Light: Can create holographic clones that hurt. X's uncharged Soul Body does a similar thing, with it destroying enemies just by collision. They can be dispersed in one hit if struck by his weakness.
Logical Weakness: As a hologram generator, lightning attacks over load the damaging duplicates and Split Mushroom's advanced electronics. Additionally, it's very difficult to hold onto a wall and attack while being electrocuted.
Mushroom Man: The only fungus-based maverick in the entire series.
Pintsized Powerhouse: Don't let his size fool you. He can be a real pain in the ass.
Psychopathic Manchild: Split Mushroom enjoys make-believe and is actually playing Superhero in the Japanese version, thinking of X/Zero as villains. This aspect is not present in the English one due to the removal of certain spoken lines.
Split Mushroom: "Hurry up and let's play!"
Split Mushroom: "Let's play "hero"! You're the "bad guy", okay?"
Rolling Attack: Zero's weapon, based on his midair rolling.
The Social Darwinist: The Japanese version outright stated that he doesn't need "weak friends".
Spin Attack: Several of his attacks involve him spinning around.
Use Your Head: His Desperation Attack causes him to land on the ground headfirst and emit dangerous spores.
Wall Crawl: More like wall-cling, but still.
X-Ray Sparks: When electrocuted. If he is summoned his full clone when it happens, the clone will also act like it's been shocked.
You Have Outlived Your Usefulness: A disturbing take where it wasn't the settings' primary villains who did it to him.

Storm Owl

Staff Chief of the Skies

"You’ve really, REALLY turned my unit to scrap, huh? I’ll return the favor in kind!"

Japanese Name: Storm Fukuroul

A horned owl-based Reploid and one of Repliforce's most resourceful generals. Storm Owl regards the entire staff of Repliforce as family and was extremely resentful when he and his associates were branded as Mavericks by the Hunters. After the Repliforce coup began, he launched the air brigade of hammerhead shark-shaped airships to divert the Maverick Hunters' attention.

Weapon: Double Cyclone/Tenkuuha

Weakness: Aiming Laser/Rakuhouha

Voiced by: Kazuo Oka (JP)

Airborne Mook: Storm Owl is able to fly around the place, only landing when he uses some of his more powerful attacks.
Arm Cannon: Uses it to fire air projectiles at X or Zero.
Authority Equals Asskicking: A high ranking officer of Repliforce and a powerful combatant.
Badass Boast: Only in the Japanese version before the boss fight.
Storm Owl: "Target spotted. I'll eliminate it in five minutes."
Bird People: He is an owl robot.
Blow You Away: Has several air-based powers, including an air Elemental Barrier, air projectiles, and can even summon tornadoes.
Cultured Badass: According to supplementary material, Owl is especially skilled at nighttime operations and was one of Repliforce's most resourceful generals. This is why he was respected by the entire staff of the Repliforce air brigade.
Desperation Attack: Two of them. One of them summons three damaging columns of tornadoes, the second one has him go into the middle of the screen and does a Chasing Your Tail move with four streams of wind balls. He calls the latter attack his "trump card".
Elemental Barrier: When damaged, he puts up a wind barrier around himself that can block shots (except for his weakness), the basis for Zero's Tenkuuha.
A Father to His Men: To Papa Wolf levels. Indeed, he takes X/Zero's attack on his forces very personally.
Storm Owl: "You'll face the retribution for making us into your enemy!"
Feathered Fiend: An Owl Reploid who is a pretty dangerous Maverick.
Feather Flechettes: One of his attacks fires out a spread of them.
High-Class Glass: Appears to have a monocle-like lense on his eye.
Land, Sea, Sky: Representing Sky (Repliforce's Air Force).
Levels Take Flight: The first half of his stage will have you cutting your way through his fleet, and the second half is set on his personal airship.
Logical Weakness: Small size and high mobility won't help him evade a lock-on laser weapon or a screen-filling attack.
The Napoleon: More than Split Mushroom.
Ominous Owl: An Owl Maverick who has less-than-good (if somewhat understandable) intentions.
Pintsized Powerhouse: One of the smallest bosses in the game, yet he comes with a slew of attacks (and many of them damaging).
Precision F-Strike: In the Japanese version, he called X/Zero a "damn little bird" (as in the baby bird) as one of his Boss Banters.
Storm Owl: "You damn little bird! You should've stayed clinging to the ground!"
Sequential Boss: All that stands between the Mini-Boss and Storm Owl himself is a shaft devoid of enemies.
Shoulders of Doom: Adorned with his wing feathers, making them look like military epaulets.
Shout-Out: The way his airships fire their Wave-Motion Gun is awfully familiar...
Stock Animal Behavior: Swooping down on you to grab you.
Tornado Move: One of his Desperation Attacks, and X's weapon (only when charged).
Undying Loyalty: To the point where he would refuse orders that don't come from his superiors. He was also noted to be quite resentful of when Repliforce was declared Maverick even before they formally announced their independence.
Storm Owl: "Justice is on the side of the Repliforce! Let's go!"
Wind Is Green: His wind orbs and Elemental Barrier are green in color.

Web Spider

Guerrilla Commander of the Thick Forest

"How dare you branded us Mavericks! I won't let you pass! If you value your life, leave!"

Japanese Name: Web Spidus

An orb-weaver spider-based Reploid, Web Spider is a former Maverick Hunter who left recently to work for Repliforce as commander of their guerrilla unit. When Repliforce began their coup, he remained loyal to his new employers and was stationed in the jungle charged with guarding a powerful beam cannon hidden there.

Weapon: Lightning Web/Raijingeki

Weakness: Twin Slasher/Ryuenjin

Voiced by: Issei Futamata (JP)

Adaptational Villainy: Spider is much more evil and villainous in the X4 manga. Just like in the game, he is stationed in the jungle guarding Repliforce's giant beam cannon weapon. However, he is planning on using it to burn down a nearby city and kill the humans residing there, and he ruthlessly slaughters a group of Maverick Hunters who went to investigate the weapon before X shows up and puts him down. He also boobytraps the dead soldiers, turning them into puppets to attack X.
Alas, Poor Villain: In the X4 manga, a dying Spider laments about how he feels that meaningless battles between Reploids and humans, as well as among Reploids themselves, will never end. He explains he went along with Repliforce's coup because he didn't want Reploids to be doomed as "mechanical puppets" wandering in an "endless hell".
Web Spider: "They're not going to end... the conflict you speak of will never go away... as long as humans are imperfect, it stands to reason that we, created by humans, are also imperfect... as long as humans continue to deny this natural outcome as Irregular, and as long as we live in a world where pseudo-heroes like you are born, we will continue to cry out for the independence of Reploids... our relationship with humans was predetermined from the moment our first unit was invented. We Reploids are mechanical puppets that wander through endless hell while in this world..."
Animate Dead: In the X4 manga, Spider was hiding out in the Kagikira Forest and slaughtered an investigation team of Maverick Hunters who had arrived to investigate reports of a Repliforce frontline there. X later went there to investigate their disappearance, and Spider used his powers to animate their corpses and make them attack X. X decided to bear the brunt of their attacks until they ran out of ammo, which they eventually did, resulting in Spider coming down to fight X himself.
All Webbed Up: Getting hit by his electrical webs makes X/Zero get caught in them and take continuous damage.
Authority Equals Asskicking: The commander of Repliforce's guerrilla unit and quite the competent fighter.
Badass Boast: Spider gives one in the manga when he is viciously assaulting X with his spider claws.
Web Spider: Taste the skills of a professional!^note
Big Creepy-Crawlies: He is a human-sized spider Reploid.
Big "NO!": If the Twin Slasher is used to cut off the web he is hanging on.
Desperation Attack: Creates a giant web network and starts moving around it, while attacking and sending out small spider drones.
Web Spider: "This will entangle you!"^note"Karame totte kureru wa!"
Elemental Barrier: Like Storm Owl, he puts up an electric barrier that blocks shots whenever he is hit.
Flunky Boss: When low on health, he can send out small spiders to attack X or Zero.
Giant Spider: He is a human-sized spider Reploid.
High-Class Glass: Like Storm Owl, he appears to have a monocle on his eye, although it could be more of a targeting device.
Impaled with Extreme Prejudice: Zero's weapon.
Jungle Japes: The first half of his stage is set around the jungle's rivers, while the second part is in the deeper woods, with lots of robot snakes, bees, and spiders.
Logical Weakness: In X's case at least. Webs and wires get cut by slashing weapons, and the little electrified string of web he hangs from can easily be severed by a cleanly aimed Twin Slasher. Averted in Zero's case, as that weakness won't hit.
Motive Rant: He gives a philosophical one to X in the manga version after X fatally wounds him.
Web Spider: "They're not going to end... the conflict you speak of will never go away... as long as humans are imperfect, it stands to reason that we, created by humans, are also imperfect... as long as humans continue to deny this natural outcome as Irregular, and as long as we live in a world where pseudo-heroes like you are born, we will continue to cry out for the independence of Reploids... our relationship with humans was predetermined from the moment our first unit was invented. We Reploids are mechanical puppets that wander through endless hell while in this world..."^note
Outside-the-Box Tactic: X can use the Twin Slasher to cut the web he is hanging from, causing him to fall to the ground for heavy damage.
Remember the New Guy?: He used to be a Maverick Hunter Zero personally knows, yet this is the first time that we actually meet him.
Shock and Awe: His weapon is a web of electricity.
Spread Shot: Charged Lightning Web spreads out to 8 directions after its initial projectile stops.
Stock Animal Behavior: At low health, he sticks in a giant web and moves around it. Also hanging off of a string of (electric) web.
Turn Coat: He used to be Maverick Hunter but he transferred into Repliforce sometime before this game.
Undying Loyalty: To Repliforce, unsurprisingly. He even told Zero that he refused to call off the coup d'état because "he knew where his loyalties lie".
Utility Weapon: Lightning Web can provide a temporary wall for a Wall Jump.
Warmup Boss: He has very simple patterns, and can be easily beaten without his weakness; good for a starting boss. He does, however, have a homing attack (his own Lightning Web) that actually hurts, which can shock beginners who don't know what to expect.
We Used to Be Friends: With Zero, judging by their intro dialogue.
You Shall Not Pass!: His intro dialogue against X and his intro Boss Banter in the Japanese version suggests this.
Web Spider: "I cannot allow you to go through!"

Mega Man X5

General

MacGuffin Guardian: In a twist on the usual Maverick formula, X and Zero aren't going after them just because they're Mavericks, but because each of them has a part needed for the Enigma Cannon and Space Shuttle to function.
Named After Somebody Famous: Their initial English names are based off Guns N' Roses, save Skiver who is named after Michael "High in the Sky" Monroe (a temporary partner of the band used in concerts). For 17 years, the Japanese names were more or less left alone in the instruction manual. With the release of the X Legacy Collections, all of the English names were changed to keep in line with the Maverick naming tradition. Thus, the original English names will be the ones listed in parenthesis.
The Remnant: Two of them (Burn Dinorex/Mattrex and Spiral Pegasus/The Skiver) are former members of Repliforce, the militant Reploid group that was defeated in the last game.
Suicide by Cop: Most of them (except for Dark Necrobat, Spike Rosered, and arguably Burn Dinorex) got recently infected with the Sigma Virus, and they ask X/Zero to destroy them/have one last good fight before they go mindless.

Burn Dinorex

Jurassic Inferno

"Let’s fight and enjoy ourselves! Just like we always do!"

Other Names: Mattrex (PS1 English)

A Tyrannosaurus-based Reploid and a member of Repliforce's disaster prevention team, and one of the few survivors of the Great Repliforce War in X4. Dinorex was stationed in a volcano situated in Africa, and without Repliforce's knowledge, has created an illegal warehouse making weapons using magma energy. The Hunters visit him for the Booster Engine he possesses for the shuttle project.

Weapon: Ground Fire/Quake Blazer (Danchien)

Weakness: Wing Spiral/W-Shredder (Shipuu)

Blood Knight: Dinorex loves a good fight, which puts Zero and especially X into trouble when they're just asking him for the booster engine.
Breath Weapon: No points for guessing what kind of breath.
Desperation Attack: Twofold: He burns the whole ground with his flame breath, then he does a powerful lunging attack while covered in flames, with geysers rising up from his trail.
Dinosaurs Are Dragons: Not only that, Dinorex has stegosaurus-like plates made out of flame on his back. Justified, as he is a robot.
Lethal Lava Land: Like Magma Dragoon's, his stage is in a base inside a volcano. The first half has flame-spewing dragon turrets and rolling waves of lava that you have to take cover from periodically, while the second half has a branch, where you either fall into the lava with your Ride Armor or play on the surface and face a pterosaur miniboss.
Lightning Bruiser: He's one of the larger Mavericks in X5, just behind Grizzly and Whale in size, yet he moves around much faster than either while hitting just as hard.
Lizard Folk: Comes with being a Tyrannosaurus rex robot and all.
Logical Weakness: Wind blows away fire.
Not Brainwashed: Notably, even if he's fought after Eurasia itself crashed into the planet, he never shows signs of having been corrupted by the Sigma Virus. All of his fights are triggered by him being a Blood Knight or deciding it's better to go out fighting rather than eventually perish from either virus infection or on the barren world.
Playing with Fire: Dinorex utilizes fire-based attacks in battle.
Ramming Always Works: He has an attack where he rams his whole body towards you, back-first (he bends his body low enough to make his flame spikes point forward).
The Remnant: Was a member of Repliforce.
Spread Shot: Ground Fire shoots a flame projectile that, when it hits the wall or floor, shoots out small damaging embers from the spot.
Sword Plant: Quake Blazer, Zero's acquired technique.
Utility Weapon: The Ground Fire can be used to burn certain objects.
Wall Crawl: More like Wall Cling.
Wolverine Claws: Though they look more like decorations.

Crescent Grizzly

Rampaging Iron Claw

"I'm already being taken over by the virus...It's just a matter of time before I go Maverick. It's my fate to have a duel with you...please, fight me while I still have my wits! I don't want to kill you when I've lost all of my consciousness!"

Other Names: Grizzly Slash (PS1 English)

A grizzly bear-based Reploid, Grizzly is a black market weapons broker who resides in the hills of northern Russia. He has had run-ins with the Maverick Hunters in the past, even retaining a scar from Zero's Z-Saber. Despite his occupation, Grizzly seems to not like conflict, saying that he is just a weapons broker and believes that both Mavericks and Hunters are too violent and overconfident. He is in possession of the Crystal Ball for the Enigma cannon.

Weapon: C-Shot/C-Sword (Mikazukizan)

Weakness: Spike Ball/Twin Dream (Sogenmu)

Adaptational Villainy: In the game itself Grizzly is somewhere between morally ambiguous and just a little bit sympathetic. In the X5 manhua he's a sadistic thug who torments humans, even crucifying someone before X gives him what's coming to him.
Arms Dealer: Grizzly sells weapons to the black market after seizing them.
Bears Are Bad News: Kind of subverted, he is the easiest boss in the game and he gives a good weapon/technique.
Blood Knight: In his former life, Grizzly used to be a Reploid who lived for battle and took the most advanced weaponry from his fallen opponents in battle. However, in later years he decided to stick only to being a weapons broker and would sell the arms to the highest bidder. His illegal behavior put him in the croshairs of Zero, who gave him a scar in their ensuing confrontation, but left him alive.
Deflector Shields: Somewhat; charged C-shot covers X in 2 rings of energy that blocks enemy shots and damages enemies by touching them.
Desperation Attack: Shoots out 2 large crescent waves of energy.
Dig Attack: When his health drops to 2/3, he'll go on a rampage and tunnels into the ground, periodically appearing either from above to drop down on the player, from below with a drill sticking out, or from the background where he swipes with his claw.
Good Scars, Evil Scars: Has a scar going down his right eye after a past encounter with Zero.
Locomotive Level: In a variant, his stage is set on multiple cargo trucks that are moving towards his hideout in a cavern.
Logical Weakness: Plant roots grow through earth. Could also be a reference to the fable of the The Bear and the Hermit, wherein a bear has a thorn stuck in his paw.
Mighty Glacier: He is still pretty slow even when he Turns Red. Although his big claw is something not to be underestimated.
Monstrosity Equals Weakness: He is one of the biggest mavericks in the game and yet is one of the easier, if not easiest fights.
Noodle Incident: When playing as Zero.
Crescent Grizzly: "Zero! My scars ache at the sight of you…"
Zero: "You should hurry up and get that fixed."
Red Right Hand: More like a Red Left Hand, but worth qualify.
Rolling Attack: Zero's weapon, along with a Double Jump like Kuuenzan before it.
Russian Bear: He's a bear-based Reploid who resides in Russia.
Sword Beam: More like Claw Beam. It's the basis for the weapon/technique from him.
This Is a Drill: One of the functions of his red left hand.
Utility Weapon: His weapons are the only thing that can destroy the plasma ball generators in Shining Firefly's stage, one of which leads to Dr. Light's capsule.
Warmup Boss: The best boss to start the game with, since he is much, much easier than his contemporaries.
You Can't Fight Fate: Believes this to be the case.

Dark Necrobat

Forgotten Soldier of Darkness

"Keke! That's none of my concern at all, right? At this rate, me, you, the Mavericks, everyone will die. Kekeke! I’ll start the death toll with you!"

Other Names: Dark Dizzy (PS1 English)

A vampire bat-based Reploid, created for Sigma's army three years prior to the events of X5. He was able to escape before seeing use by the Mavericks, and remains in hiding even though Sigma has forgotten about him entirely. Necrobat resides in a planetarium northwest Sudan and possesses the Fuel Tanks required for the shuttle.

Weapon: Dark Hold (both characters)

Weakness: F-Laser/C-Flasher (Messenkou)

Airborne Mook: He likes to cling to the ceiling in the first half of the fight, then adds hovering just above the floor into his pattern.
Ax-Crazy: He's downright giddy about the prospect of the world ending.
Bat Out of Hell: Necrobat is notably the only Reploid boss in X5 who was a Maverick from the start.
Dark Is Evil: He has dark powers and unlike the rest of the Mavericks, he was evil from day one.
Desperation Attack: He'll do several sound wave attacks, then he does the Dark Hold and try to attack you up close.
Expy: He is essentially the reploid version of Shade Man, possessing a similar Life Drain attack, and sound wave projectiles. A major difference is that his obtainable Dark Hold ability functions like Flash Man's Time Stopper.
Fangs Are Evil: A given due to being based after a bat.
Flunky Boss: Can summon groups of Bat Bones.
Gravity Screw: The second half of his level has switches that flip the floor and ceiling.
High-Class Glass: It adds to his vampiric motif.
Logical Weakness: A bat with shadow powers doesn't take well to light-based weapons.
Make Some Noise: Can emit sound waves that damage the player. They can block X's shots too, save for Falcon Armor's charged shot, or charged F-Laser.
One to Million to One: His battle intro has a swarm of Bat Bones coalesces then fly away, revealing him.
Space Zone: More like a Planetarium Zone, at least in the first part; it has lots of stars in the background, and images of constellations that turn into Bat Bone and falling spikes periodically. The second half has multiple gravity generators that flip the stage upside down.
Stock Animal Behavior: Grabbing you and draining your health as well as releasing sound waves.
Time Stands Still: His Dark Hold.
Token Evil Teammate: While most of the other X5 Mavericks are Tragic Monsters driven into madness by the Sigma virus, Necrobat was always a Maverick and it's not even clear if he's infected by the virus.
Utility Weapon: The Dark Hold is useful for avoiding the laser traps in the first Zero Space stage, akin to the Flash Stopper in Mega Man 2 before it.
Verbal Tic: "Squeak" in the English version, and "Kekeke" in the Japanese version.
Winged Humanoid: He has the wings of a classical vampire.

Shining Firefly

Radiance of Intelligence

"This body of mine... has already infected by the "poison"... I'm well aware that what I'm saying is wrong. At the very least... allow me to go out on my own terms. This is the end... put me at peace."

Other Names: Shining Hotarunicus (JP); Izzy Glow (PS1 English)

A firefly-based Reploid scientist and the world's leading researcher in laser technology. He resides in a fortified laboratory near the Kuril Islands, rarely allowing his work to see the light of day out of fear that it would be used for weapons. The Maverick Hunters require his Laser Device in order to complete the Enigma cannon.

Weapon: F-Laser/C-Flasher (Messenkou)

Weakness: Tri-Thunder/E-Blade (Denjin)

Big Creepy-Crawlies: He is modeled after a firefly.
Desperation Attack: Sends out multiple energy balls onto the floor, then goes to the other side of the screen to retract them.
Evil Genius: Played with. His design heavily invokes the "old professor" stereotype, but he was a good guy before his infection by the Sigma Virus, and decides to fight X and Zero to see just they're made of with his own two eyes before he fully succumbs.
Giving Someone the Pointer Finger: Before the fight starts.
Homing Projectile: He controls his F-Laser to home into the player character.
Logical Weakness: An enemy that spends most of his time airborne is certainly vulnerable to electric attacks. Plus, he's a bug, so using lighting on him is reminiscent of bug zappers.
Mad Scientist Laboratory: His stage is a lab inside a castle, with spiked ceiling traps and plasma ball generators.
Miniature Senior Citizens: He has the look of an old professor thanks to his glasses and white "mustache", and is pretty short.
No Man Should Have This Power: How he felt about many of his inventions, not trusting others with them out of fear of them being weaponized. This includes the Maverick Hunters themselves.
Player-Guided Missile: F-Laser fires a firefly drone whose path can be controlled to move to any of the 4 directions. Not only that, the drone will leave small Hard Light afterimages that can hurt enemies. X will be immobile whenever it's out, however.
Reluctant Mad Scientist: He mentions that he's already been infected by the Sigma Virus, and asks for the heroes to put him down before he goes mad for real.
Shorter Means Smarter: A Reploid scientist that's both highly regarded in his field and the smallest Maverick boss in the game.
Spread Shot: Zero's C-Flasher, much like Rakuhouha before it, is a Multidirectional Barrage that hits all onscreen enemies.
Stock Animal Behavior: Somewhat, his glowing tail is based on fireflies' glowing abdomen, and he can fire lasers from it.
Stroke the Beard: In his character art.
Unusual Weapon Mounting: His tail can shoot lasers. It's based on real fireflies' glowing abdomen.
Utility Weapon: F-Laser can be used to hit things beyond your normal reach, like the Dr. Light's capsule in Dark Necrobat's stage.
Wave-Motion Gun: One of his normal attacks. Charged F-Laser also shoots this.

Spike Rosered

Scarlet Witchcraft

"Hey, hey... you’re in for it now! I’ll do anything to win! Game time!"

Other Names: Axle the Red (PS1 English)

An eccentric rose-based Reploid, Rosered originated from a very rare mutation between a Reploid, the nature control unit of a Ukrainian jungle, and the Sigma Virus. As this strange mutation was determined a potential threat, Rosered hid himself in an abandoned Repliforce military base, now running a black market trade by stealing technology from the area. The Maverick Hunters require his Orbiter Engine for the shuttle.

Weapon: Spike Ball/Twin Dream (Sogenmu)

Weakness: Ground Fire/Quake Blazer (Danchien)

Desperation Attack: Causes it to rain damaging petals, and starts attacking from both sides with his body double.
Doppelgänger Attack: Can create a body double of himself that will attack you alongside himself. Zero's acquired technique copies this.
Giving Someone the Pointer Finger: Before the fight starts.
The Hedge of Thorns: His stage is set in an artificial jungle full of flowers that can extend their vines to grab you, as well as spiky plant growths.
Hypocrite: If X comes at him needing the Orbiter Engine, he calls X a thief. If X comes at him without needing the Orbiter Engine, he'll start to muse about how if Earth gets destroyed he'd be able to steal whatever he wants in the chaos, to which X calls him a thief.
The Immune: Possibly. The Sigma Virus was involved in his creation, but he's not obviously Brainwashed and Crazy or even really Ax-Crazy, although he is quite eccentric judging by his pre-battle dialogue with X and Zero.
Lean and Mean: As his appearance shows.
Logical Weakness: Fire burns plants. Rose on Fire is the result.
Nonstandard Character Design: In the manhua, he's a humanoid reploid wearing rose-themed armor. His mask even breaks and you can see his teeth.
One-Steve Limit: Averted with two characters later on in the saga: Axl and Red, later in X7.
Petal Power: His Desperation Attack.
Pinball Projectile: Charged Spike Ball would ricochet off walls, floors, and ceilings.
Plant Person: A notable example in that he originally wasn't one, but became one due to the unexpected mutation and reaction with the Sigma Virus and the nature control unit of a Ukrainian jungle.
Redhead In Green: The red petals on his head visually invoke hair and his overall body is green.
Scary Teeth: In the Chinese-only manhua, Rosered has a set of pointed teeth.
Slasher Smile: As seen in the Rockman X5 manhua, he has a set of sharp teeth that is usually covered by a mouth plate.
Spike Balls of Doom: X's weapon.
Vine Tentacles: Can use vine whips that can entangle the player character and hurt them continuously.
The Virus: The major fear of his unexpected creation was that he could possibly be the source of a new strain of the Sigma Virus even worse than anything before it, hence the attempt to terminate him to be safe rather than sorry.
What the Hell, Hero?: He calls out the Maverick Hunters for blindly hunting "Mavericks".
Spike Rosered: "Those "Mavericks"...you called that title all on your own, don’t you? I mean, even the whole Repliforce Army were branded as Mavericks, right? What is a "Maverick" then?"
Weak to Fire: As a plant-based boss, he doesn't take too well to the Ground Fire and Quake Blazer, taking extra damage and even catching fire when hit by them.

Spiral Pegasus

Air Force Prince

"Here, the remnants of the Repliforce are seeing their last days... to be honest, all I can do now is entrusting everything to you... but, you’ll need to convince me that you’re the man for the job... through battle!"

Other Names: Spiral Pegasion (JP); The Skiver (PS1 English)

A pegasus-based Reploid who was once the young and passionate director of the Repliforce air brigade. Unfortunately, his dreams were dashed by the Great Repliforce War, after which he formed his own Reploid Air Force. He still holds great resentment towards the Maverick Hunters for ruining Repliforce and killing Colonel and Iris, which poses a problem when they require his Orbital Wing for the space shuttle.

Weapon: Wing Spiral/W-Shredder (Shipuu)

Weakness: Dark Hold

Authority Equals Asskicking: He was the director of Repliforce's air brigade.
Blow You Away: Pegasus utilizes wind-based attacks in combat.
Desperation Attack: Uses his Wing Spiral attack, where he throws tornadoes that grow larger, as well as zig-zagging around the place, trying to hit you from multiple angles.
Doppelgänger Attack: A borderline example; the W-Shredder has him sending his wind after-image to attack the player.
Foe-Tossing Charge: Which can easily knock you off the platform!
"Get Back Here!" Boss: Spends a lot of time out of range of X/Zero's attacks.
Giving Someone the Pointer Finger: Before the fight starts.
High-Altitude Battle: The plane you fight him on is implied to be in complete motion.
Levels Take Flight: His stage is set on his airship, where some Knot Berets (Repliforce grunt robots) can be found there. There are Time Bombs littered around the stage that X must destroy before they go off and dealing huge damage.
Lightning Bruiser: Especially when using his Signature Move.
Logical Weakness: An enemy known for high speed isn't as threatening if he is immobilized.
Marathon Boss: The weapon "strong" against him isn't even a damage-dealer (which is even worse when playing the mission with X), plus his tendency to fly at an incredible speed and disappear from the screen, makes for a long battle for casual players.
Pegasus: Obviously, as that's what he's based on.
Platform Battle: It takes place on his plane, like Storm Eagle before him. However, the plane is much smaller, which adds extra danger to the battle.
Pride: According to the Mega Man X Legacy Collection 2 gallery, his pride led him to make costly mistakes.
The Remnant: Was a member of Repliforce, which was prominent during X4, and commands one its surviving units, redubbed The Reploid Air Force.
Shoryuken: Aside from it being one of Skiver's moves, X launches his Wing Spiral with a jumping uppercut.
Spell My Name with a "The": When he was known as "The Skiver".
Tornado Move: the Wing Spiral.
Undying Loyalty: He is still loyal to Repliforce, especially Colonel.
Wind from Beneath My Wings: He launches his Wing Spiral by flapping his wing.

Tidal Whale

Guardian Deity of the Oceans

"X, my boy... I'm a man of the sea... and I won't give the ocean freely. I understand I'm acting like a fool. I just wanted to have a fight with you, like a man!"

Other Names: Tidal Makkoeen (JP); Duff McWhalen (PS1 English)

A sperm whale-based Reploid who serves as both the curator of an oceanic museum and the commander of a maritime garrison. His stubbornness and sense of responsibility for the ocean has brought him to frequent arguments with the Repliforce Navy. Whale guards the North Atlanic Ocean, which is needed to produce the Hydrogen necessary for the Enigma laser cannon. However, by the time the Hunters find him, he has already been infected with the Sigma Virus and requests to die in battle.

Weapon: Goo (Gel) Shaver/F-Splasher (Hisuisho)

Weakness: C-Shot/C-Sword (Mikazukizan)

Advancing Wall of Doom: He creates a pattern of ice blocks that pushes the player. Later, his ice blocks push you towards a spiked wall.
Animals Not to Scale: As noted from the interviews with the developers, he (a whale) looks smaller than Frost Walrus.
Aquatic Mook: Is fought underwater, being a whale.
Authority Equals Asskicking: He is both the strongest and the leader of his navy.
Dash Attack: Zero's F-Splasher modifies his air dash into a damaging one.
Desperation Attack: He goes to the other side of the screen, and now his ice blocks push you into a spiked wall of instant death.
Fish People: Whale person, specifically.
Jurisdiction Friction: As the captain of a maritime security force, he and Repliforce's Navy would often get into disputes due to his own headstrong nature having him charge into crises without a second thought.
Large and in Charge: Of his maritime garrison as well as the Reploid museum.
Marathon Boss: Even his weakness only does slightly more damage than X's full charge shot. Combined with how his ice blocks push you away, the fight with him is going to be longer than others. C-Shot's charged version, at least, speeds up the process.
Sequential Boss: The last fight against the U-555 Mini-Boss (a Rise to the Challenge sequence) takes place just outside Whale's room.
Smart Bomb: Somewhat similarly to charged Sonic Slicer, charged Goo Shaver fires off many ice blocks upward which then fall to the ground, covering a large area.
Under the Sea: The whole stage is set in the seas, where you fight a submarine called U-555; you destroy its front, then its "tailfin" and then its top, all filled with cannons. The middle part of the stage also explores a ship wreckage.
Underwater Boss Battle: The entire level is underwater, and Whale's room is no exception.
Utility Weapon: His weapon is used to hit the bomb beyond a small gap that blows up the barrier blocking you from the Dr. Light capsule.

Volt Kraken

Super Electromagnetic Trap

"You're always so pushy... I’m glad I resigned my position as a Hunter. I don't want to be rude too."

Other Names: Squid Adler

A giant squid/Kraken-based Reploid. He was once a Maverick Hunter in the 6th Naval Unit, and a friend/relative of Launch Octopus. However, after doubting the purpose of the Hunters, he resigned to instead work at an energy facility in the Korea Strait. The Maverick Hunters require his Energy Cartridge for the Enigma cannon, but he is unwilling to cooperate knowing that X killed Launch Octopus. He is also infected by the Sigma Virus, going Maverick mid-conversation with the Hunters.

Weapon: Tri-Thunder/E-Blade (Denjin)

Weakness: Goo (Gel) Shaver/F-Splasher (Hisuisho)

Agent Peacock: In the Japanese version, he speaks in a fairly feminine manner. He occasionally ends his sentences with "wa yo" and "wa ne", both endings commonly used by women. This changes when the Sigma Virus takes over, as he then uses the very masculine pronoun "ore" to refer to himself and uses "omae" to refer to the Hunters, with "omae" being a rough, masculine way of saying "you".
Airborne Mook: He is always seen flying in battle, and only touches the ground when he uses his ground pound attack.
Defector from Decadence: He resigned from the Maverick Hunters because he was starting to disagree with what they were doing, devoting himself to energy research as a more "peaceful" lifestyle.
Desperation Attack: Extends his tentacles to fire out a barrage of wall-crawling electricity.
Diabolus ex Machina: He got infected by the Sigma Virus on the spot when talking to X/Zero.
Fish People: More of a squid person, but being a squid robot makes him one.
Flying Seafood Special: And he likes to fly near you too!
Ground Punch: He can electrify the floor doing so.
Logical Weakness: Water can short-circuit electrical currents.
Personal Space Invader: Once Kraken loses some of his health, he begins to chase his opponent for contact damage.
Shock and Awe: Kraken utilizes electric-based attacks in combat.
Shoryuken: Zero's acquired technique, the E-Blade.
Spread Shot: Tri-Thunder goes forward, upward, and downward each shot.
Temporary Platform: He can create a floating cube in his fight, that interacts with his electric shots. He can also make an electrified floating cube.
Tragic Monster: The only Maverick where you actually see the Virus take him over. He was actually willing to deal with you peacefully before that.
X-Ray Sparks: If he's hit by his weakness.
You Killed My Father: Actually subverted, his brother Launch Octopus was destroyed by the Maverick Hunters, but he doesn't hold it against them. In fact, he says that doing so was part of the Maverick Hunters' duty. Once the Sigma Virus takes him completely, though, it becomes a double subversion, with Kraken screaming at X about how he intends to avenge Launch Octopus.

Mega Man X6

General

Adaptational Villainy: In the Archie Comics crossover event "Worlds Unite" all their sympathetic qualities vanish and they are reduced to nothing more than obstacles for the heroes to destroy (compare them to X4's Colonel and Iris, who were also Tragic Villains but were not revived by Sigma, with Zero noticing this), though Wolfang took his loss to Okami in stride.
Back from the Dead: They've been mentioned as being dead long before the events in the game, and they're revived by Gate.
Calling Your Attacks: Some of them yell out attack names, like Commander Yammark's FORMATION!, Metal Shark Player's various summons, and more famously Blaze Heatnix's MAGMA STREAM! and GOD BIRD!
Dragon Their Feet: They naturally serve as the obligatory Boss Rush, even though it happens after Gate is defeated.
Distinguishing Mark: All eight of the Mavericks have a rhombus-shaped gem located on their forehead, identifying them as Nightmare Investigators and their relationship to Gate.
Make It Look Like an Accident: Several of them were retired by sabotaged incidents or labeled as Mavericks and are killed on the spot.
Tall Poppy Syndrome: Specs-wise they surpass all previous Mavericks and are comparable to X and Zero in that their programs are so advanced that they can't be analyzed. But instead of being appreciated like X and Zero are, the researchers who put them to work feared them and were jealous of their creator. So through whatever means possible, the researchers found ways to destroy (or bully into destroying themselves) all eight of them, though more than half of them were doing things or did something that probably would have gotten them executed, tech specs or no.
Tragic Villain: Out of the eight of them, half of them (Blizzard Wolfang, Commander Yammark, Rainy Turtloid, and Shield Sheldon) are completely sympathetic characters who did nothing wrong (though Shield Sheldon's extrajudicial termination of Dr. Jim before his Maverick condition got out of hand might be borderline). Two others are more morally ambiguous without reaching outright evil status (Ground Scaravich who was a thief who poked around in extremely restricted areas and Metal Shark Player who resurrected destroyed Reploids unlawfully). Only Blaze Heatnix and Infinity Mijinion avert this outright.
Undying Loyalty: The majority of them are loyal to Gate.
Utility Weapon: Most of their weapons are useful against the Nightmare Phenomenons that occur after you exit/finish their stages. For example, Magma Blade vs. the falling fireballs or Metal Anchor vs. the moving iron blocks.
Woobie, Destroyer of Worlds: Several of them were retired without them doing anything wrong to justify it, beyond their really high specs. Especially for Turtloi. Granted, Heatnix and Mijinion are quite assholes and Player's actions are questionably ethical, but still.

Blaze Heatnix

They told me to brainwash Reploids, but as if, right? I don't want to do something lame. Hey, will you fight me? I'm the best!"

An arrogant Phoenix-based Reploid made by Gate to withstand extreme temperatures to search for subterranean hotspots. Heatnix joined a volcanic disaster relief team, but because he was so much more powerful than his teammates, he would often ignore them. This led to a series of workplace accidents that could have been avoided with his cooperation, and he was euthanized for his neglect. Gate later revived him as a Nightmare Investigator and sent him to the magma area.

Weapon: Magma Blade/Shoenzan

Weakness: Ground Dash/Sentsuizan

Voiced by: Shin-ichiro Miki (JP)

Airborne Mook: He is always seen flying.
Blood Knight: He likes being a Maverick and cuts loose on the player.
Boss Bonanza: There are six minibosses in his level. Arguably a Recurring Boss, since it's the same Nightmare Snake fought in six different conditions.
Death from Above: His Nightmare Phenomenon triggers a rain of fireballs, even in Blizzard Wolfang's level.
Desperation Attack: He disappears, then flies from one side to the other while covered in a massive amount of flames. This is then repeated in a reversed way.
Even Evil Has Standards: Subverted, as he doesn't want to brainwash Reploids because he considers it "lame" rather than because of any moral objections.
Feathered Fiend: A Phoenix-based Reploid, and is an arrogant individual, to begin with.
Flaming Sword: What X will get from him. As for Zero, it is modified into an upward slash.
Giggling Villain: He chortles to himself as he admits how much he enjoys killing other Reploids.
Gravity Screw: Can somehow summon purple non-lethal magma (that deals a large amount of damage) from above that stays there.
Jerkass: Most of the Investigators have this nature of loyalty or wanting to be left alone, only killed because of spite. The player can have some form of sympathy with them. Heatnix however relishes his uncaring actions.
Large Ham: Just listen to him scream "MAGMA STREAM!"
Lethal Lava Land: Somewhat. It does have spewing flames in the earlier part of the stage, as well as rising lava and later a lava pool, but the theme is downplayed compared to the previous volcano levels.
Logical Weakness: Earth can be used to douse the fire. In spite of water-based and ice-based weapons.
Might Makes Right: His mentality.
Mundane Utility: Zigzagged, as he was built with a very high heat tolerance so that he could safely enter dangerous areas (specifically underground hotspots) without being destroyed, much like Rainy Turtloid. But unlike the gentle Turtloid, Heatnix let his strength go to his head, eventually becoming convinced that any Reploids that couldn't keep up with him deserved to die.
Not Helping Your Case: Before Heatnix was revived by his creator, Gate's jealous colleagues were already looking for anything they could use against him. Heatnix's cocky attitude did not help matters then.
The Phoenix: He's got the bird features and the Playing with Fire powers. About the only thing, he doesn't have is Resurrective Immortality.
Playing with Fire: Heatnix utilizes flame-based attack in combat. He can also manipulate magma.
Shoulders of Doom: That are on fire.
Psycho Supporter: He supports Gate's plans and has the personality of a casual killer.
Smart Bomb: Charged Magma Blade summons fireballs that covers much of the screen.
Smug Super: He was very aware he was the most powerful member of his squad and viewed the rest of them as weak burdens at best for it. Unfortunately, his sheer arrogance didn't do him any favors in endearing him to others, especially when it caused problems that costed lives.
The Social Darwinist: Was proud enough of his power to view others as weak and worthless in comparison to himself, and when confronted by X and Zero he compliments their strength and expresses a desire to test how they stack up to himself.
Token Evil Teammate: In the days before the Nightmare Investigators turned Maverick. Even back then, Heatnix was still an asshole who deserved to be retired.
Winged Humanoid: His bright red wings make him somewhat visually reminiscent of the Gundam Heaven's Sword from Mobile Fighter G Gundam.
Wreathed in Flames: In his Desperation Attack, though he's already quite burning normally.

Blizzard Wolfang

"Forgive me, but you will die here, Maverick Hunter!"

A wolf-based Reploid created by Gate as the leader of a research team stationed at the North Pole. One day, he and his team were attacked by Mavericks and all were killed save for Wolfang, who was able to dispose of all the Mavericks himself. Researchers who opposed Gate took advantage of the incident and schemed to dispose of Wolfang, deceiving Alia into casting him into the cold sea, making it look like an accident. Gate later revives Wolfang as one of the Nightmare Investigators.

Weapon: Ice Burst/Hyoroga

Weakness: Magma Blade/Shoenzan

Voiced by: Hideo Ishikawa (JP)

The Atoner: He sees his past as a sin that he must atone for, which he reveals if confronted by Zero.
Breath Weapon: He fires his Ice Bursts from his mouth.
By the Lights of Their Eyes: Before the fight with him starts, the room inexplicably goes dark, then his glowing eye appears on the screen, then the light comes back, revealing him.
Ceiling Cling: Can stick to the ceiling and then fires lots of Ice Bursts. It is also the basis for Hyoroga.
Desperation Attack: He can dash along the wall, floor, and ceiling, leaving ice spikes in their wake. X's charged Ice Burst is based on this.
Friendly Enemy: He and Zero know each other and the two exchange cordial words before Wolfang's "new mission" forces them to come to blows. He even asks Zero not to think badly of him, as it's not personal, just him doing his duty.
Let No Crisis Go to Waste: The attitude of the researchers who masterminded his death. They waited until his team was attacked by Mavericks and then tricked Alia into disposing of the damaged Wolfang.
Logical Weakness: Extreme heat can melt ice.
Mistaken for Murderer: His tragic fate.
Must Make Amends: His mentality.
Noble Wolf: A firm, loyal bodyguard of Gate, to the very end.
Shout-Out Theme Naming: All the captive Reploids in his level are named after other Capcom characters.
Slippy-Slidey Ice World: His stage is set in an icy cavern. The early and middle part has periodic avalanches while the later part will have falling ice blocks that you have to carefully move around to proceed.
Stock Animal Behavior: Howling before the battle, as well as Running on All Fours.
Undying Loyalty: To Gate as his bodyguard.
Utility Weapon: X's weapon allows him to create a temporary platform, while Zero's Special Weapons grant him Ceiling Cling like Wolfang.
Wolf Man: A wolf-based Reploid.
Weak to Fire: As an ice-based boss, he doesn't take too well to Magma Blade or Shoenzan, taking extra damage and even catching fire when hit by them.

Commander Yammark

"I don't trust you! Who knows what the Maverick Hunters and Reploid researchers are thinking... I'll end up being betrayed and killed again anyway! I'll get rid of you first!"

A dragonfly-themed Reploid created by Gate to lead an observation team for a nature preservation project. While on duty, Yammark accidentally started a fire that burnt a large portion of the forest. He was never directly accused of the incident, but eventually someone sabotaged his flight system, leading him to a lethal crash. Gate has revived him as a Nightmare Investigator, but due to this betrayal Yammark has developed an understandable paranoia.

Weapon: Yammar Option

Weakness: Ray Arrow/Rekkoha

Voiced by: Wataru Takagi (JP)

Airborne Mook: With those wings, he can fly anywhere in the arena he wants.
Attack Drone: His Yammar Options, which he can command in various unique ways. Most of the time they're used to cover him. X and Zero's Yammar Options also play like this.
Attack Pattern Alpha: Yammark has three attack styles with his dragonflies.

Commander Yammark: Formation: Guard!

Commander Yammark: Formation: Final!

Commander Yammark: Formation: Wing!

Big Creepy-Crawlies: Based off a dragonfly and is larger than X and Zero.
Commanding Coolness: Though it's more of an Informed Attribute, since not only is he subordinate to Gate and High Max, but he also has a very fearful and cowardly personality completely unsuited to a commander.
Cool Shades: Which he is never seen without.
Critical Status Buff: Upon getting low health, he'll summon more and more drones to command.
Forest Ranger: Yammark was created to lead an observation team for a nature preservation project.
Giving Someone the Pointer Finger: At the start of battle.
Invincible Minor Minion: His Nightmare Phenomenon causes a swarm of small indestructible insects to surround the heroes. Especially bad for X, whose buster fire will be obstructed. Luckily, enough hits will cause them to fly off.
Jungle Japes: In a variant, the stage also has a cave in the middle.
Logical Weakness: Lasers are notorious for disrupting pilots and their flight equipment. In addition, dragonfly eyes can be very sensitive to light, which is what the Ray Arrow is made of.
Lost in Translation: It's difficult to tell if he was supposed to set controlled burns in the forest or if fire had nothing to do with his job. Either way, the fire got out of control.
Multi-Directional Barrage: Charged Yammar Option makes the drones shoot all over the screen from multiple different angles while also turning them invincible for a short time.
Mundane Utility: He was created to command an ecological observation team, and his dragonfly drones were built so that he could patrol gigantic sections of forests all by himself.
Nonstandard Character Design: It is easy to miss, but the human eyes under his visor imply that he is a human Reploid in dragonfly-themed armor, rather than a dragonfly-man Reploid.
The Paranoiac: As noted, he was convinced just about everyone was out to get him. As it turns out, he was right about the researchers at least.
Punny Name: "Yammark" sounds like "on your mark" in English. Either this was intentional or not isn't clear.
Warmup Boss: Yammark is easy to beat, even without Ray Arrow. The Yammar Options are easy to destroy and he himself lacks much in terms of health or attack options without them outside of just plain slamming into X/Zero, meaning it's easy to shave off a good chunk of HP before he can summon more.
Winged Humanoid: Has four wings like an actual dragonfly.

Ground Scaravich

Well, well, I would be. It's just X, isn't it? That won't do. I've been found by quite the relic, haven't I?"

A dung beetle Reploid treasure hunter, wanted by the Maverick Hunters for damaging historic ruins in his search for valuable data. When Gate sent Scaravich to a forbidden area (the laboratory where Dr. Cain discovered X), Alia was forced to intercept and, despite her conscience, kill him. Scaravich was later resurrected by Gate as a Nightmare Investigator and sent to Central Museum to examine the Nightmare.

Weapon: Ground Dash/Sentsuizan

Weakness: Yammar Option

Voiced by: Takeshi Aono (JP)

Affably Evil: Scaravich uses polite language toward the Hunters in the Japanese version, conjugating his verbs formally with desu and masu. Notably, he is the only Nightmare Investigator out of eight to do so.
Benevolent Architecture: Avoiding his main form of attack would have been a whole lot harder if it weren't for the convenient ledges high at the top of his room.
Big Creepy-Crawlies: He is not that big compared to others, but still.
Boss Bonanza: Once X/Zero escapes each of the Randomly Generated Levels, the Totems will act as minibosses that will block the way forward.
Dishing Out Dirt: His whole attack pattern is just rolling out balls of mecha dung to attack X or Zero with. At first they're barely larger than he is, but keep destroying them and they'll just keep getting bigger and bigger.
He Knows Too Much: Partially the reason why Alia killed him, and also because of his previous crimes of burglarizing ancient ruins in search of treasure.
Increasingly Lethal Enemy: If you destroy his rocks too much, he'll replace them with bigger and bigger ones, making it harder to jump over him.
Logical Weakness: Certain species of scarab beetles, such as the Japanese beetle, are preyed upon by dragonflies.
Miniature Senior Citizens: Based on his appearance, he is senile.
The Napoleon: Not as much as other "little bastard" Mavericks like Split Mushroom or Infinity Mijinion, but he does have an ego on him and does challenge X or Zero rather than run away from them.
Pintsized Powerhouse: He can push a ball of rock that is many times larger than he is.
Randomly Generated Levels: There are 4 "totem holograms" that will teleport the player character towards another part of the stage; there are 8 of those parts, 4 of which will be chosen from them every time you enter the level. Among them are the rooms containing the Heart Container, a Light Capsule, and a teleport portal towards the stage's secret area, all of which are randomly chosen.
Scarab Power: Like many scarabs, he is often found near sites of ancient ruins. However, what he does is raiding those ruins.
Stock Animal Behavior: Rolling a ball of rock.
Stroke the Beard: Like Shining Firefly before him, the character art has him holding the ends of his mustache-like structures on his mouth.
Super-Strength: His boulders can get really huge, yet he's able to maneuver them just as easily as with his original small one.
Temporary Platform: His Nightmare Phenomenon creates these in four colors: Brown, Red, Purple, Black (the first two can be destroyed, although the red platforms can cause an explosion, and the latter two can be pushed).
Tough Beetles: He's based on a dung beetle, and, despite his diminutive size, he's a Pint-Sized Powerhouse who can effortlessly push the ball of rock many times larger than himself.
Treasure Hunter: His effective occupation.
Warm-Up Boss: Similar to Yammark, Scaravich is a rather easy boss to defeat despite the randomized hell his level can unleash. As long as X/Zero gets behind him they're effectively in the clear to wail on him, and as long as they avoid destroying his boulder to make him grab bigger ones it will remain small enough that it's easy to jump over and not even use the hanging ledges of his boss room.

Infinity Mijinion

"Hold up. Seriously? Give me a break! It was still being tested! I was planning on using Illumina to crush them! Now I'm pissed off! I'll kill you instead and get praise from Gate to boot!"

A daphnia/water flea-based Reploid created by Gate to test-pilot large manned weaponry. Mijinion was often arrogant and hasty, and would completely ignore the testing program, putting many of his associates in peril. Eventually, Mijinion was killed in a sabotaged test made to look like an accident. Gate later revived Mijinion as a Nightmare Investigator and sent him to a weapons manufacturing plant, where Mijinion immediately began constructing a massive Mechaniloid called Illumina.

Weapon: Ray Arrow/Rekkoha

Weakness: Guard Shell

Voiced by: Wataru Takagi (JP)

Airborne Mook: He is always seen flying.
Ax-Crazy: A borderline example.
Blown Across the Room: If the Guard Shell's reflected projectile (or its charged shots) hits him, he'll be slammed towards the wall and then automatically clone himself. Sometimes X's full charge shot or Zero's Z-Saber combo will send him backward too.
Blackout Basement: Triggering Mijinion's Nightmare Phenomenon would result in X/Zero having to traverse certain levels in the dark.
Big Creepy-Crawlies: He is modeled after a water flea.
Doppelgänger Attack: His clones can create a swarm of slowly homing fluorescent surprisingly-durable bubbles.
Energy Ball: He can shoot these to 8 directions, or fire them along the ground while many small lasers fall from above. They're the only 2 things he shoots the Guard Shell can reflect.
Energy Weapon: His Ray Arrow attack.
The Friend Nobody Likes: Inverted. We never find out what the other Investigators think of Mijinion, but we sure know what he thinks of them, as he grouses about how he has to "cover up for the lack in ability of the other investigators" when playing as X and even refers to them as "useless fleas" when playing as Zero.
Humongous Mecha: He is in charge of maintaining one, Illumina. He apparently referred to it as "her" (or "Illumina-chan" in the Japanese version). The whole stage is spent trying to stop it as it attacks from the background.
Hypocritical Humor: In the English version, he calls the other investigators "useless fleas", even though he's themed after a water flea himself.
Increasingly Lethal Enemy: He'll clone himself every so often, so if you take too long, it'd be harder to hit him since he'll be hidden within his clones and those bubbles.
Informed Species: While the resemblance is there, at first glance he looks less like a humanoid water flea and more like a little fat man in a spacesuit. He also resembles a tardigrade, an animal that is in an entirely different phylum.
Insufferable Genius: Very convinced he was the best there was at what he did. He certainly was smart, but his sheer arrogance caused plenty of problems, especially when he was willing to forgo testing to rush out his works which put people in peril.
Logical Weakness: Barriers can block laser attacks.
Mad Scientist: More like Mad Engineer, but close enough.
Make It Look Like an Accident: How he was killed off.
Marathon Boss: Due to how he flies around the stage, getting easily hidden between his clones^noteHint: his clones never move at all, and his Weakness weapon is difficult to use against him, it'll take a good while to defeat him (at least without Ultimate Armor).
Nonstandard Character Design: Mijinion's design is fairly typical by the series' standards, but how it's rendered in-game is not. All of his sprites are drawn in a profile view, rather than the more traditional 3/4ths view that most other Maverick boss sprites use.
Pillar of Light: Charged Ray Arrow summons a bunch of these to cover X. Also used with Zero's Rekkoha.
Rage Against the Legal System: Unlike all the other Nightmare Investigators, he wants revenge against the "thick-headed so-called authorities" who had him destroyed and creates a giant robot named Illumina to carry it out for him.
Reckless Sidekick: He obeyed Gate's orders but also pursued his own self-serving ambitions, and even Gate himself couldn't fully rein him in.
Self-Duplication: He can create duplicates of himself in order to confuse the player and provide extra firepower. These duplicates can also take a decent beating before dying, and if you're not careful it's possible to result in a swarm of them on-screen all at once.
Sequential Boss: Unless you go to his level's Nightmare Area, all there's left after destroying Illumina is to fight Mijinion himself.
Smart Bomb: Zero's Rekkoha.
Stock Animal Behavior: Water fleas are known for their Explosive Breeder quality, and Mijinion does something similar here.
Token Evil Teammate: Like Blaze Heatnix, he exhibited Maverick behavior even in the days before the Nightmare Investigators turned Maverick. His one redeeming trait is that, unlike Heatnix, his actions never got anyone killed, though that was more just dumb luck than any prudence on Mijinion's part.

Metal Shark Player

"Heh heh heh. Aren't you packed with some great DNA? Would you like to have your DNA data analyzed?"

A hammerhead shark-based Reploid created by Gate as a member of a recycling research team. His job was to oversee the analysis and control of DNA at the facility. Player's impressive abilities in DNA analysis soon led him to experiment in DNA resurrection; being a practicioner of DNA resurrection himself, Gate encouraged this despite its illegality. Player's activities were eventually discovered and he was executed as punishment. Gate later revives him as one of his Nightmare Investigators, putting him back in charge of a recycling plant.

Japanese Name: Metalshark Player

Weapon: Metal Anchor/Rakukojin

Weakness: Meteor Rain/Ensuizan

Voiced by: Mugihito (JP)

Anchors Away: Player utilizes an anchor as his weapon.
Bad Powers, Bad People: Necromancy is usually an ability reserved for the villainous, and Player is no exception with his Reploid necromancy. There's some implication he was more neutral in a For Science! way before he was retired, but that's gone after coming back as a Nightmare Investigator.
Death from Above: He can sometimes fall to the ground head-first to smash X/Zero. Zero's acquired technique takes cues from this.
Eternal Engine: His stage is set in a recycling plant with lots of Descending Ceilings that acts as press disposer.
Evil Sorcerer: His practice of using DNA to resurrect Reploids made him be viewed as the equivalent of these by the authorities, who wasted no time in having him destroyed.
Extra-ore-dinary: When he resurfaces after going under the junk, balls of it will resurface with him and cause collision damage to X or Zero if they hit.
Fossil Revival: The Reploid equivalent. The Mavericks he revives during his boss battle have all been destroyed for at least 3 games back.
It Must Be Mine!: His entire character is just obsession with Reploid DNA. Interestingly, he'll mention that he doesn't need Zero's DNA when facing him, which foreshadows The Reveal that it was Zero's DNA that was responsible for the Nightmare to begin with.
Logical Weakness: He uses metal as a weapon, and water rusts metal. It is implied that Meteor Rain is actually acid rain, just like the rain in Rainy Turtloid's stage, which can - and does - kill aquatic animals, as well as corroding metal.
Necromancer: He excels in "Reploid DNA Resurrection" and he can create clones from various old Mavericks out of junk. In fact, X can pick up his power by charging his Metal Anchor to summon a barrage of iron Storm Eagle clones.
Sequential Boss: After the Nightmare Pressure is destroyed, Player's arena is just nearby.
Shark Fin of Doom: When he swims beneath the junk metals, his fin sticks out and could hurt you.
Shark Man: A shark-based Reploid.
Smart Bomb: Charged Metal Anchor summons falling Storm Eagles that cover the whole screen. Be careful, however, as it leaves X immobile and vulnerable, and the Storm Eagles disappear instantly if he's hit.
Temporary Platform: Player's Nightmare Phenomenon.
Threatening Shark: He is a Maverick modeled after a hammerhead shark.
Token Evil Teammate: Played with. Compared to Heatnix or Mijinion being total assholes who didn't care if lives were endangered by their actions, Player's obsession with harvesting Reploid DNA and reviving fallen Reploids is certainly played for all the moral and ethical questionablity it's worth, but no mention is ever made that he tried to kill someone to take their DNA (at least before his own revival) and was fully content with working on the already-deceased. In fact, it was Gate who encouraged him to keep researching into it despite the legal ramifications. Indeed, Player was originally a research recycling team employee who specialized in taking the junk parts of destroyed Mavericks and preparing them for re-use as materials for new Reploids, which is perfectly benevolent in and of itself. Player's ability at performing DNA research was so outstanding that he won a promotion to the position of chief of the recycling facility.

Rainy Turtloid

"I came back to this world with a purpose, which he bestowed upon me. Even though I've disgraced him, I was given life again by him. That's why... I must fulfill this task, even if it costs my life..."

An amphibious turtle-based Reploid created by Gate as a member of a water purification team. Turtloid's shell was designed to withstand the harshest of acid rains, and thus he was one of the few Reploids with permission to explore restricted "Level A" polluted areas. However, concerns grew that his defensive capabilities were overkill, and many researchers demanded that Gate weaken him. Gate refused to comply and was punished for it; Turtloid felt responsible and took his own life out of deep guilt. Gate later resurrected the gentle Turtloid as a member of the Nightmare Investigators and sent him to Inami Temple.

Weapon: Meteor Rain/Ensuizan

Weakness: Ice Burst/Hyoroga

Voiced by: Hideo Ishikawa (JP)

Animals Not to Scale: What's the biggest Maverick in the series? The bear? The rhino? The mammoth? The whale? Nope, it's a turtle.
Attack Its Weak Point: Attack and destroy the two crystals on his back to make him vulnerable. They will regenerate after a while, though, so repeat the process.
Badass Back: His in-game sprite always has him facing out of the screen, showing off his large shell. Which also conveniently exposes his main weak points.
Death from Above: Charged Meteor Rain summons many globs of water from above that can cover most of the screen.
Rainy Turtloid: Heaven's wrath! (Ten no Ikari!)
Driven to Suicide: Out of concern to his creator getting in trouble due to him otherwise.
Gentle Giant: A mild-mannered, giant turtle Reploid.
Hostile Weather: Turtloid's Nightmare Phenomenon is acid rain that gradually whittles down X/Zero's health.
I Did What I Had to Do: Even if it costs his life.
Large and in Charge: The biggest standard Maverick boss in the series.
Logical Weakness: Aside from being water-elemental, his stage is also riddled with rain, making him susceptible to ice attacks.
Luckily, My Shield Will Protect Me: He has the most HP out of the Nightmare Investigators and like High Max must be attacked in a way that exploits his vulnerability, as he is invulnerable to attacks otherwise.
Macross Missile Massacre: Turtloid can fire several missiles from the jewels on his back.
Making a Splash: Turtloid utilizes water-based attacks in combat, although it is only used after he has 1/2 of his health left.
Mighty Glacier: Aside for being known for his excellent defense, he has the strength to complement it, but he's pretty slow, being a turtle. This was actually the reason his creator was asked to weaken down his defense in the past (which he never did).
Mundane Utility: The researchers who worked with Turtloid feared his defensive capabilities could be dangerous (or at least that was their excuse) but in truth he was so fortified only so that he could enter the most polluted areas without being destroyed and help purify them. And with his gentle personality, that's all he ever would have used them for if the researchers hadn't bullied him into taking his own life and driven his creator into exile and ultimately madness.
My Master, Right or Wrong: Turtloid's Undying Loyalty to Gate takes precedence over his morals and self-preservation.
Religious Bruiser: Possibly, given that he shouts "Ten no ikari!" (which translates as 'Heaven's Wrath!') when using his Meteor Rain attack.
Respected by the Respected: He respects X and Zero who in turn respect and don't want to fight him, with X even saying so outright.
Rolling Attack: He can retract into his shell, then jut out spikes from the sides, and then roll around the stage, sometimes rolling up the wall and ceiling in higher difficulties. Zero's acquired technique does something similar.
Spike Balls of Doom: He rolls into one to attack the player.
Sturdy and Steady Turtles: He is built with high defensive capabilities for the purpose of exploring areas with high levels of pollution. However, his defensive capabilities were deemed too great, and many demanded that he should be weakened.
Stock Animal Behavior: Retracting into his shell.
Sturdy and Steady Turtles: A massive turtle Reploid who boasts some of the most impressive durability of any Reploid out there.
Super-Toughness: X and Zero can't even scratch him until they destroy the two crystals in his back, and that can take awhile unless you use his weakness weapon.
Temple of Doom: His stage is a preserved old temple riddled with acid rain.
Undying Loyalty: To the point he was willing to kill himself just to make sure his boss wouldn't suffer.
Villain Respect: Despite being against the Maverick Hunters, Turtloid, even with his massive defensive/offensive capabilities, knows that X/Zero will triumph against him regardless as he no doubt realizes how far X/Zero has traversed in both experience and skill.
X: Turtloid! I know you can understand. You know what you should do right now.
Rainy Turtloid: X, I understand what you mean, but it's my duty. It's also my duty to eliminate anything that disturbs my master...X, my life is yours!
X: No! I don't want to fight you!

Shield Sheldon

"I couldn't do a thing to prevent the professor from going Maverick. I was forced to kill him because of my incompetence as a bodyguard. But I've been granted a second chance... and this time, I'll fulfill my duty without fail. I'll protect him, even if it costs my life!"

A giant clam-based Reploid created by Gate as a bodyguard for chiefs of research institutes. He was assigned to a laser researcher named Dr. Jim - however, he was forced to kill Dr. Jim when he suddenly went Maverick. To make matters worse, the Maverick Hunters who arrived on the scene interpreted Sheldon as the Maverick and he was charged accordingly. Unable to deal with the stress and shame of the incident, he took his own life. Gate later revived Sheldon as a Nightmare Investigator.

Japanese Name: Shieldner Sheldon

Weapon: Guard Shell

Weakness: Metal Anchor/Rakukojin

Voiced by: Hirotaka Suzuoki (JP)

The Ace: Gate created Shield Sheldon to serve as a bodyguard for important people, and Sheldon was excellent at his job. Sheldon often protected individuals with VIP status, and Sheldon had such an impeccable service record in protecting his charges that he was highly sought-after for bodyguard service, leading to him often protecting top-flight researchers belonging to well-funded science organizations. This is from supplementary material from the Mega Man X Legacy Collection 2 Gallery.
Attack Reflector: Aside from his Guard Shell, his Desperation Attack's 4 shells will return fire if they're struck by any attack.
Shield Sheldon: Go ahead and try me! (Watashi wo mikitte miro)
Blown Across the Room: Getting hit by his Weakness will send him flying towards the wall and deal big damage.
Deflector Shields: His Guard Shell.
Desperation Attack: Two of them, the first is to surround himself with Guard Shells while floating around, the second one has him summon four shells and will fly from one shell to another.
Doppelgänger Attack: He has 2 attacks where he splits himself into 2.
Driven to Suicide: Sheldon took his own life after considering himself as useless.
Failure Knight: Shield Sheldon was created by Gate to serve as a bodyguard for important people (mainly chiefs of other research institutes). Sheldon apparently failed in his job as a bodyguard when Dr. Jim, a laser researcher he was protecting, went Maverick. However, Dr. Jim was still able to control himself. Nevertheless, Sheldon still felt it necessary to dispose of Jim because of his Maverick corruption, but his actions were misinterpreted by the Maverick Hunters that arrived on the scene and he was hunted as a Maverick himself. No longer being able to deal with the shame of the incident and being a fugitive, he committed suicide. Eventually, Gate resurrected him.
Flying Seafood Special: A flying humanoid clam robot.
Light and Mirrors Puzzle: His stage is filled with laser-shooting drones, mirrors that reflect the lasers, and doors that open by shooting a laser to it.
Logical Weakness: Metal implements such as anchors can be used to easily crush and pry open clam shells.
Luckily, My Shield Will Protect Me: And in his case, his shield can even reflect enemy blasts if he chooses to use them for that purpose.
Mercy Kill: Presumably why he terminated Dr. Jim before his Maverick condition got out of hand.
My Greatest Second Chance: He believes that being revived by Gate to serve him as this.
Power Floats: He is always floating in the air.
Removable Shell: He can remove both of his shells and use them to attack his opponent.
Shell Game: Literally in his case; when he Turns Red he sends his shells to four corners of the Boss Room and hides in one of them before flying off to another shell.
Stock Animal Behavior: Retracting into his shell.
Teleport Spam: Teleports around the stage often.
Throwing Your Shield Always Works: He can throw out his two clam shells to attack the player from afar.
Undying Loyalty: To Gate, as he views serving him as My Greatest Second Chance.

Mega Man X7

General

Bounty Hunter: All of them are members of Red Alert, an unsanctioned Maverick-hunting syndicate.
Brainwashed and Crazy: To some extent. Sigma has infected them all with the Sigma Virus and can easily exert control over them, but it seems that they still retain their wills (with the exception of Hyenard, who is driven totally insane instead). It's more of a Manchurian Agent situation.
Dragon Their Feet: Like the Nightmare Investigators, they're part of the traditional Boss Rush, even though their boss Red is already dead by then. Justified in that Sigma, who you fight next, had secretly taken control of them with the Sigma Virus.
Forced into Evil: While morally grey, no one in Red Alert ever had dreams of world domination or killing the Maverick Hunters - not even the coldest of the group, Splash Warfly.
Spirit World: The boss rematch room resembles a graveyard with teleporters in front of each tombstone. Upon entering a teleporter, a Maverick is fought in a discolored, digital/spirit version of their old arena.
With Great Power Comes Great Insanity: Sigma creates power-ups for Red Alert using the DNA data they collect, but also infects them with the Sigma Virus at the same time to force them into subservience.

Flame Hyenard

Crazy Warrior Cloaked in Flames

"BURN! BURN TO THE GROUND!"

A hyena-based Reploid, gone completely mad thanks to the Sigma Virus, and doesn't seem to be aware of his own actions, merely lashing out at the Maverick Hunters and howling in pain. He dwells within a geothermal power plant in Africa.

Weapon: Circle Blaze (+ Double Bullet)/Bakuenjin

Weakness: Splash Laser/Suiretsusen

Voiced by: Wataru Takagi (JP), Peter von Gomm (EN)

Ax-Crazy: Due to the Sigma Virus.
Colossus Climb: Hyenard rides on top of a large gazelle-like Mechaniloid that the heroes must climb.
The Hyena: Not exactly a laugher, but he does spam his infamous Madness Mantra of "BURN! BURN! BURN TO THE GROUND!"
Logical Weakness: Water can put out fire.
Pyromaniac: If his catchphrase didn't tell you already.
Tortured Monster: A lot of his insanity comes from the fact that the virus leaves him in constant agony, and he only attacks the player under the assumption that they're responsible for his condition.
Self-Duplication: He can create two clones of himself and run around the Maverick Hunters along with them. Attacking the real one is the only way to avoid taking damage.

Ride Boarski

Charging Man

"Oink-wa—! You brat! I oughtta take the likes of you and...! A duel! Just you and me! Yeah!"

Japanese Name: Hellride Inobusky

A feisty boar-based Reploid who laces a highway in northern Canada with time bombs as part of Red Alert's challenge. He is very quick to anger, especially if you insult his pride - which is exactly what the Maverick Hunters do.

Weapon: Moving Wheel/Zankourin

Weakness: Circle Blaze/Bakuenjin

Voiced by: Tessho Genda (JP), Ryan Drees (EN)

Badass Biker: Boarski was a wild maniac of a biker who prowled the highways at night, as stated by supplementary material in the Mega Man X Legacy Collection Gallery.
Bowdlerise: Just look at the first part of his Japanese name. Too much for some, perhaps.
Deadly Lunge: One of his attacks is to grab X/Zero/Axl and ram them into the electric fence surrounding his arena.
Flunky Boss: Runnerbombs from outside the arena can attack those within.
Full-Boar Action: A fearsome boar, though he has vents in place of tusks.
Hair-Trigger Temper: He has an extremely touchy personality, well-befitting the actual nature of a wild boar. So much that his speech can degenerate to Angrish easily at times. His temper is so out of control, he goes berserk at the drop of a hat, and if given the slightest insult, proceeds to run down the target of his aggression, complete with the added injury of tearing it to ribbons. With his fierce, rebellious attitude, there's absolutely no way of reasoning with him, giving the Maverick Hunters little other option than to do him in.
King Mook: Speculated to be related to the Crash Roader enemies. Lampshaded by Zero:
Zero: Are you guys remnants of the Road Attackers?^note
Ride Boarski: Argghaa! How dare you group us with those punks! You'll get it for this!
Zero: Oh, so you must be the Road Riders, then?^note
- TEPPEN, as seen in this image, later confirms Zero's questions.
Logical Weakness: Extreme heat can melt typical rubber tires, or detonate gasoline.
Mad Bomber: The Highway mission has the Hunters try to disarm the bombs planted by Boarski. In the battle itself, Boarski can throw bombs as he rides around the arena.
Names to Run Away from Really Fast: His Japanese name.
Shock and Awe: He can summon electric beams that rotate in the arena.
Stealth Pun: He is a boar robot who can transform into a motorcycle. He's a hog bike!
Stock Animal Behavior: Charging around.
Transforming Mecha: Boarski can transform into a motorcycle mode.

Snipe Anteator

Keeper of the Electronic Labyrinth

"Hohoh!! Now, I want you to fight like normal. I need to get good data on you, boy!"

Japanese Name: Snipe Ariquick

An elderly anteater Reploid and Red Alert's resident tech specialist. He is dangerously wise, taunting Zero about his past and waxing philosophical with X over the cycle of war. He awaits the Maverick Hunters in a digital maze located in India.

Weapon: Sniper Missile/Hieijin

Weakness: Moving Wheel/Zankourin

Voiced by: Mugihito (JP), Barry Gjerde (EN)

Armor-Piercing Question: When playing as X.
X: How long must this madness go on?
Snipe Anteator: Hahaha! Let me ask you - how long has this madness been going on?
X: ?!
Snipe Anteator: The annals of history contain endless records of war... the "madness" will never end.
Attack Drone: Modeled after ants, no less.
Backpack Cannon: Has a cannon on his back, which itself is attached to a large pack of sorts that drags behind him, reminiscient of an anteater's bushy tail.
The Cracker: Red Alert's resident tech specialist. In the prequel story included with the game's soundtrack, Axl calls his skills at tampering with cyberspace "unmatched".
"Get Back Here!" Boss: One of his patented strategies is to retreat to a part of the pillar where you can't reach him with most of your attacks.
Homing Projectile: Uses homing attacks, and his Special Weapon for the heroes gives them each a form of homing missile.
Logical Weakness: A sniper will struggle against moving targets.
Old Soldier: Implied from his lines. Being old, weak but strategic and knowledgeable helped.
Overly-Long Tongue: Being an anteater, this is fairly obvious. He can use it to grab the player.
Spell My Name With An S: Yes, his name is Anteator.
Stock Animal Behavior: Using the tongue to capture prey.
Wolverine Claws: Rather than directly attack, Anteator uses them to electrify the column.

Soldier Stonekong

Strongarm of the Deepest Green

"Now, no more talk! Let our swords speak for us! Only the victors will be viewed as righteous in the eyes of history."

A gorilla-based Reploid who occupies the jungles of North Africa. He is one of the few Red Alert members who is fully aware that he is being manipulated by Sigma (the other two being Red and Tornado Tonion). However, he doesn't seem to regret being used for evil, as he only fights for loyalty, not justice.

Weapon: Gaea Shield/Gokumonken

Weakness: Explosion/Hadangeki

Voiced by: Tessho Genda (JP), Walter Roberts (EN)

Affably Evil: He's polite and respectful to all three player characters, especially Zero, as he genuinely praises him and calls him peerless.
BFS: Stonekong wields a large sword in combat, which he will swing at you if you get too close. It can be easily destroyed by shooting at it or stabbing it if you are playing as Zero.
Blood Knight: Stonekong himself says that he only lives to fight.
Cultured Badass: He has a philosophical and inquisitive nature, interrogating X on his definition of what strength and war are, and speaks in a refined and articulate way.
Dishing Out Dirt: He'll conjure up a boulder that splits in two if he clings to the pillar in the center of the boss arena.
Graceful Loser: When he loses to you, his last words have him yell "Good job!" (English) or "Migotoda!" (Japanese for "Amazing!")
Killer Gorilla: A combat Reploid based on a gorilla, King Kong to be exact, and a fierce and competent fighter as well.
Logical Weakness: Even the sturdiest of boulders can easily fall to explosives.
Luckily, My Shield Will Protect Me: Somewhat subverted, he uses his shield to attack the player by throwing it, but never uses it to block attacks.
Only Sane Man: Stonekong was aware that Red Alert is actually being manipulated. He only chooses to fight because of his loyalty to the group.
Sequential Boss: The stage's Mini-Boss, a number of statues that circle and attack the heroes, will be immediately followed by the confrontation with Stonekong.
Undying Loyalty: Stonekong knows that Red Alert is being manipulated by the Professor, but since it has already happened, he will stay with them as he fights for loyalty.
The Walls Are Closing In: One of his attacks does essentially the same thing.
Worthy Opponent: He views Zero as one due to his respect for the hunters strength and skill.

Splash Warfly

Pursuer from the Blue Sea

"Rusted old machines should stay home and play with their toasters! Kee-hee-hee, take this!"

A snide and cold-hearted flying fish Reploid, who holds dominion over the northern Pacific Ocean with a fleet of battleships. He claims to have hated Axl from the start and has no qualms with killing him.

Weapon: Splash Laser/Suiretsusen (+ D-Glaive)

Weakness: Volt Tornado/Raijinshou

Voiced by: Hirotaka Suzuoki (JP), Ryan Drees (EN)

All According to Plan: Said word-for-word against Zero. It Makes Sense in Context.
Boss Bonanza: There are a total of three minibosses in his level: a grounded fighter aircraft, three Dragon Blasters, and finally the battleship itself.
Fish People: He is based on a flying fish.
Hit-and-Run Tactics: After making an attack or getting hit with the weapon he's weak to, Warfly will jump back into the water surrounding the platform he's fought on.
In Your Nature to Destroy Yourselves: Warfly voices this opinion of Reploids if X battles him.
Splash Warfly: Kee-hee-hee! So you're the famous X?! I thought you were out of commission!
X: I was put back on the job, thanks to you creeps!
Splash Warfly: So you're saying we're playing too rough? Fool! This is our natural state - just like you!
X: No!
Jerkass: He is pretty rude to all three hunters. Axl apparently never even liked him in the first place.
Logical Weakness: Water is a strong conductor for electricity. Additionally, he doesn't have much room to dodge Zero's Shoryuken-style attack once he emerges.
Making a Splash: Warfly utilizes water-based attacks in combat.
Platform Battle: Take extreme caution since it's a fatality in all directions, being a 3D arena and all.

Tornado Tonion

Dancing Assassin

"Around and around!"

Japanese Name: Tornado Debonian

An eccentric onion-based Reploid who takes over a radio tower in Japan, from which he broadcasts silly and annoying messages. He is one of the few aware of Sigma's devious influence on Red Alert, and despite not wanting to be involved, finds himself trapped.

Weapon: Volt Tornado (+ Ray Gun)/Raijinshou

Weakness: Gaea Shield/Gokumonken

Voiced by: Wataru Takagi (JP), Jack Merluzzi (EN)

Acrofatic: He constantly does ballet like twirls in his battle, at high speeds even.
Affably Evil: Isn't really sadistic or deranged, just careless and fun-loving.
Big Fun: An evil example.
Blow You Away: Uses wind and electricity to fight.
Fat Bastard: Downplayed. Tonion is rather portly, but is more childish than genuinely malicious. Averted when it’s shown that bulk is actually armor plating he can detach and manipulate. Without it, he’s actually on the skinnier side.
Floating Limbs: His arms float next to his body, connected by coils where his shoulders should be.
Funny Foreigner: His german-sounding accent, goofy high pitched voice, broken english, plus his hyperactive and eccentric personality in the english dub invoke this.
Germanic Depressives: Inverted. He has a german-sounding accent in the english dub and has a goofy and energetic personality.
Laughably Evil: He is easily the least threatening Maverick in the entire series, and has only taken over the Radio Tower to broadcast his dancing.
Logical Weakness: Typical rocks and boulders won't conduct electricity.
Manchild: Implied by his mannerisms, lines, and his mangled grammar.
Only Sane Man: Among the few members of the Red Alert who is aware that they're being manipulated by "The Professor".
Plant Person: He is modeled after an onion.
Suicide by Cop: He actually asks X to kill him and stop Red Alert because he regrets what he's doing.
Tornado Move: His Volt Tornado.

Vanishing Gungaroo

Pure Wildchild

"Stop treating me like a kid! Why I oughtta..."

Japanese Name: Vanishing Gungaroon

A kangaroo-based Reploid who controls an underground military base in eastern Canada. He loves to cause destruction and hates being called a kid.

Weapon: Explosion (+ G-Launcher)/Hadangeki

Weakness: Wind Cutter/Souenbu

Voiced by: Rumi Kasahara (JP), Lenne Hardt (EN)

Boxing Kangaroo: When his Ride Armor is destroyed, he attacks with martial arts.
Bratty Half-Pint: He is roughly half the height of the Maverick Hunters, and upon being told by X stop his destructive antics, his response is essentially: "Shut up, you can't tell me what to do!"
Deflector Shields: He has two shield abilities.
Dynamic Entry: To confront the Hunters, Gungaroo drops from a great height on his Ride Armor.
Kangaroo Pouch Ride: His Ride Armor is styled after a mother kangaroo, with its cockpit being in its "pouch".
Logical Weakness: Traditionally, boomerangs were used to hunt animals in Australia such as kangaroos.
Mad Bomber: Loves blowing things up, almost like a kid with action figures.
Manchild: Gungaroo talks and acts like a spoiled child, and is belittled by Zero and Axl for such. It's a wonder how he became a part of Red Alert in the first place.
Mini-Mecha: The only boss in the X series to ever use a Ride Armor, apart from Vile.
Stock Animal Behavior: Punching/kicking the player character.
Zerg Rush: Before facing Gungaroo, the Hunters must face an onslaught of Ride Armor enemies.

Wind Crowrang

Dark Winged Rival

"Hmph... I can see it in your eyes... you would prefer to avoid a fight..."

Japanese Name: Wind Karasting

A fearsome crow Reploid who flies a fleet of airships over the equatorial Atlantic Ocean. He once had a friendly rivalry with Axl and is reluctant to fight him, and also seems aware of Sigma's interest in Zero.

Weapon: Wind Cutter/Souenbu (+ V-Hanger)

Weakness: Sniper Missile/Hieijin

Voiced by: Katsuji Mori (JP), Jeff Manning (EN)

Feather Flechettes: Homing exploding feathers!
Feathered Fiend: Crowrang mocks X's ideal of a utopia, and is quite cruel.
Hidden Depths: It's implied in his dialogue with Axl that he is reluctant to fight him, moreso than any other member of Red Alert. His dialogue with Zero also implies he knows about Sigma's interest in him.
Homing Projectile: His spinning blades pursue the Hunters, and he can fire two homing missiles too. Ironically, his weakness is a homing missile too.
Logical Weakness: Staying in the air and hovering in the background doesn't do you much good against a weapon that homes in on you. Funnily enough, he has a homing attack of his own.
Winged Humanoid: Like Storm Eagle, he has six limbs. Two arms, two legs and two wings.

Mega Man X8

General

Apocalypse Cult: In a way. They act as if the uprising was inevitable, and simply seek to usher it on. This is more clear in their leaders Vile, Sigma, and Lumine, but still stands.
Back from the Dead: Averted for once; the Boss Rush is with New Generation Reploids that shapeshift into them (and back into their original forms as they explode). That's right, a Mega Man Boss Rush is actually explained for once!
Colour-Coded for Your Convenience: Their boss rematch pods each have a distinct color, and Lumine is surrounded by color-coded crystals that he absorbs whenever he wants to use a specific boss' attack:
- Optic Sunflower: Yellow.
- Dark Mantis: Purple.
- Gravity Antonion: Magenta.
- Earthrock Trilobyte: Orange.
- Gigabolt Manowar: Light Blue.
- Avalanche Yeti: White.
- Burn Rooster: Red.
- Bamboo Pandamonium: Green.
Fantastic Racism: Many of their pre-fight banters have some contempt for older model Reploids, even their prototype Axl, and their leader Lumine's ultimate plan is to destroy them all along with humanity.
Not Brainwashed: As new generation Reploids, they're actually immune to the Sigma Virus because their Copy Chips give them extended control over their own bodies. However, that doesn't stop them from going Maverick of their own will.
We Can Rule Together: Downplayed. As Axl is the prototype of their kind, some of them treat him with respect, perhaps with the intention of swaying him to their side. Others treat him as a fossil little better than a pre-new generation Reploid. To some extent, they'll also comment about how their master is interested in Zero in various ways, but none of them care for X.

Avalanche Yeti

Guardian of the Eternally Frozen Fields

"Your world... your ideals... are incomprehensible to my master."

Japanese Name: Ice-Snow Yettinger

A yeti-based new generation Reploid that worked at an environmental research center in Antarctica. While Yeti is concerned about the world's environment, when he became a Maverick, he tampered with the control system of the facility.

Weapon: Drift Diamond/Hyouryuushou/Ice Gatling

Weakness: Thunder Dancer/Raikousen/Plasma Gun

Voiced by: Youichi Sasayama (JP), Dave Pettitt (EN)

Bigfoot, Sasquatch, and Yeti: He is designed and named after a Yeti and he has the size to match it.
Death from Above: His Desperation Attack has him make snowflakes fall from the top of his arena. It lasts until he goes down.
Desperation Attack: Makes it rain snowflakes that freeze the player on contact when he Turns Red. The attack stops when Avalanche Yeti goes down.
Elemental Barrier: He can cover himself in bits of snowflakes and then charge at you. Charged Drift Diamond also does this for X.
Gatling Good: What Axl will get from him, of An Ice Gun variety.
Hailfire Peaks: His level combines Auto-Scrolling Level (with Ride Chasers) and Slippy-Slidey Ice World.
An Ice Person: He uses ice in various ways to attack.
Lightning Bruiser: Yeti is quite an agile fighter for a bulky Reploid.
Logical Weakness: Being cold while also being made of metal will turn you into a superconductor for electrical attacks.
More Dakka: Ice Gatling.
Non-Indicative Name: While his name suggests he is a yeti, he is based more on a snowman.
Reploid Popsicle: What will happen to the heroes if Yeti connects with his ice shield and Desperation Attack.
Shoryuken: He can burrow beneath the snow and then spike you with a flying uppercut if he's right under you. It's even called that for Zero if he equips the K Knuckle.
Spread Shot: Drift Diamond fires ice chunks in 2 diagonal directions, like Twin Slasher before it.
Worm Sign: When he goes underneath the snow, you can track him by the trail of disturbed snow he creates.

Bamboo Pandamonium

Fallen Giant of the Forest

"Did you know that the earliest form of rocketry was missiles used for war? All of history has been spent making things whose sole purpose is to destroy. Missiles... Reploids..."

Japanese Name: Bamboo Pandemonium

A giant panda-based Reploid, Pandamonium was in charge of the rocket center in Booster Forest, a space research facility in China used before the Jakob Orbital Elevator was built. After it was abandoned, he stayed at the facility. When he became a Maverick, he collected data on the rockets in the facility for Sigma. His goal is to help the world be destroyed, as his life here has convinced him that it's what the world wants.

Weapon: Green Spinner/Youdantotsu/Blast Launcher

Weakness: Melt Creeper/Enkoujin/Flame Burner

Voiced by: Sazame Manda (JP), Jonathan Love (EN)

Angrish: Zig-zagged. When his health has been reduced low enough to trigger his Overdrive Attack, sometimes Bamboo will shout "It's all over!" while charging it, but other times he literally says this:
Bamboo Pandamonium: "Arrrrgh, abububububuuh!"
Arm Cannon: A combo of them on each arm.
Armor-Piercing Attack: Zero's Youdantotsu and X's and Axl's weapons.
Backpack Cannon: He fires his Blast Launcher from his back.
Bamboo Technology: He shoots exploding bamboo shoots at you!
Bear Hug: His "immobilization" attack. This does a lot of damage and you have to call in your partner to get you out.
Bears Are Bad News: Largest Maverick, deceptive reach and speed, a move that's pretty much a OHKO.
Blade Spam: Youdantotsu + D-Glaive = Renyoudan, a series of 4 wood-elemental strikes. Pandamonium himself also does this sometimes if you're close enough.
Death from Above: Pandamonium fires out a rocket (or two) that arcs into the air. 5+ seconds later during his next attack, it lands on top of you and blows up, and if you're trapped by bamboo shoots it may be impossible to evade. A charged Green Spinner also works like this.
Desperation Attack: A powerful forward thrust that deals a heavy amount of damage and can destroy Ride Armors in one hit. On hard mode, it is a hard-to-avoid One-Hit Kill if you haven't purchased any Life Ups, encouraging you to save his stage for later.
Grapple Move: Bamboo Pandamonium can try to grapple your character in his arms and crush them. It can be escaped by calling the partner.
Green Thumb: Manipulates bamboo-based weapons.
Grenade Launcher: The Blast Launcher.
Guns Akimbo: His dual Arm Cannons, which also contain claws.
Hailfire Peaks: His stage is a mix of Eternal Engine and Jungle Japes, being a space research facility inside a mountainous forest area.
In Your Nature to Destroy Yourselves: He often talks about how history has been spent on making destructive inventions and that it is what makes the world be in the current state now - desolate and war-torn.
Logical Weakness: Fire burns plants. Panda On Fire is the result. Also, this guy carries an explosive payload.
Man on Fire: More like "Robot on Fire", but Bamboo reacts this way to the Melt Creeper that Burn Rooster uses as a weapon.
Megaton Punch: Bamboo Pandamonium uses this move for his Desperation Attack, which does the most damage in the game aside from Lumine's Paradise Lost.
Mighty Glacier: Moves only sparingly and slowly, but has great firepower.
Rapid-Fire Fisticuffs: One of his other attacks involves him rapidly punching his opponents with his claws.
Stuff Blowing Up: Many of his attacks are explosive-based.
Weak to Fire: As a plant-based boss, he doesn't take too well to the fire based weapons, taking extra damage and even catching fire when hit by them. The bamboo pillars he creates can also be burned down quickly.
Wolverine Claws: Pandamonium claws that prove rather deadly in his Desperation Attack.

Burn Rooster

White-Hot Fowl

"This is what you mean when you speak of justice? It's you who should be scrapped! There's no place for Reploids like you in the new world we will create!"

Japanese Name: Burn Kokekokker

A red junglefowl-based Reploid who worked at a waste disposal center in South America that harnesses the heat of a volcano to incinerate garbage, including retired Mavericks (something he became utterly sorry towards them for). Referring to the disposal center as a Reploid graveyard, and being resentful with his work, Burn Rooster became a Maverick and caused an uprising in the disposal center.

Weapon: Melt Creeper/Enkoujin/Flame Burner

Weakness: Drift Diamond/Hyouryuushou/Ice Gatling

Voiced by: Kyouzou Kudou (JP), Jonathan Love (EN)

Desperation Attack: Produces fire columns on the sides of the arena, limiting your movement.
Diving Kick: His Enkoukyaku (though he calls it "Enkoujin"), which also has him rebounding against walls and the raising pillars as he dives. Zero can also do this by using Enkoujin with K-Knuckle.
Dub Name Change: His original name was Burn Kokekokker.
Energy Absorption: If Rooster is hit with weak or uncharged attacks, he will power himself up by spawning red flames around himself on the first hit, orange flames on the second, purple flames on the third and then finally a fiery blue aura on the fourth. Rooster will shout "I'll show you my true power!" (さあ、見せてやるぜ！, Saa, misete yaru ze!) when he reaches this Blue Flame Power state. Rooster's attacks become more powerful and dangerous afterward. Rooster will degenerate down to purple flames and further below if he is repeatedly hit with powerful attacks, shouting "No!" (くそ！, Kuso!) as it happens. Rooster can continuously power up to this state even if knocked out of it, if he is further hit with weak attacks.
Extremity Extremist: He mainly attacks with his kicks.
Feathered Fiend: A rooster-based Reploid and is a cocky person to match.
Fire-Breathing Weapon: Axl's weapon.
Ground Wave: His Melt Creeper is a wave of flames creeping on the ground. X can also do this; when charged up, it sends 2 larger waves to the opposite sides of X.
Hailfire Peaks: His stage is a waste disposal center inside a volcano.
Human Popsicle: Well, more like Robot Popsicle, but if you put out his flames with the Drift Diamond, this guy will freeze.
Logical Weakness: Extreme cold can snuff out flames and suck away heat. Rooster Popsicle: the result. Alternately, much like with Fire Man, extreme cold and extreme heat can be damaging due to temperature shock.
Meaningful Background Event: Burn Rooster can be seen attacking the plant's reactor before confronting the Hunters, which might explain the Rise to the Challenge after defeating him.
Playing with Fire: Fire figures into a lot of his attacks, which befits his name.
Sword Plant: The attack that Zero will get from him.
Turns Red: He will periodically ramp up his attack power unless you can break his barrier or freeze him with his weakness.
Verbal Tic: He sometimes shouts "Koke!" in Japanese version before the boss fight.
What the Hell, Hero?: Calls out the Maverick Hunters about destroying Mavericks. Zero nonchalantly lampshades it:
Burn Rooster: "All I'm doing is listening to the cries of pain...The cries of all the Reploids you've sent here because you decided they were Mavericks."
Zero: "If you can hear all that, I guess that means you're a Maverick too, huh?"
Burn Rooster: "Ha! You'll realize soon enough who's right and who's wrong in this struggle."
Your Princess Is in Another Castle!: Defeating him isn't the end of the mission. You have to Rise to the Challenge against the lava before reaching the finish at the top. Did Burn cause this to happen by kicking the plant's reactor prior to his fight?

Dark Mantis

Deadly Blade Lurking in Darkness

"You don't understand a thing, do you? There is no such thing as good and evil. You haven't realized that yet, have you?"

Japanese Name: Darkneid Kamakil

A praying mantis-based Reploid. Mantis was in charge of security for an underground military facility in Africa with an advanced security system, but when he became a Maverick, he used the facility to produce weapons for Sigma.

Weapon: Shadow Runner/Rasetsusen/Black Arrow

Weakness: Shining Ray/Tenshouha/Ray Gun

Voiced by: Tsuneyoshi Iwatsuru (JP), Tommy James (EN)

Above Good and Evil: He claimed that there is no such thing as good or evil.
BFS: His Desperation Attack briefly enlarges his Sinister Scythes, which allows him to cover a larger area with his slashes.
Blackout Basement: During the fight, the brightness in the room randomly changes, but it's usually dark. By activating the light generator on his stage, however, the battle is much easier. Optic Sunflower's weapon also lights up the room for a short time. Also applies to his stage, complete with Patrolling Mooks.
Blade Below the Shoulder: His "mantis scythes" are folded into his arms when not in use.
Casting a Shadow: Is capable of throwing boomerangs and arrows made of darkness.
Cyber Ninja: A ninja mantis robot who uses technology to fire boomerangs and blades of darkness.
Dark Is Evil: Mantis has dark color scheme and is also a Maverick.
Desperation Attack: Jumps into the middle of the screen, and does two HUGE circular slashes, each covering about 3/4 of the screen.
Grapple Move: He can do a mantis' grab move; if you get trapped, you can summon an ally to get you out.
Homing Projectile: His Shadow Runner. Also Axl's Black Arrow; strangely, Mantis' own Black Arrow doesn't home in.
Life Drain: If he manages to grab you.
Logical Weakness: Light flushes out darkness.
Names to Run Away from Really Fast: His Japanese name.
Ninja Pirate Zombie Robot: A ninja mantis robot with a cowboy accent.
No, You: His dialogue with X after defeating at least four other Mavericks:
Dark Mantis: "Hey there, X...Looks like you can't accept the fact that we're not Mavericks."
X: "Are you making weapons for Sigma here? Is Sigma controlling you?"
Dark Mantis: "What exactly is controlling YOU, X? Hm? Your precious 'justice'? Is that it?"
Precision-Guided Boomerang: His Shadow Runners are semi-homing boomerangs.
Rolling Attack: What Zero will obtain from him. With K-Knuckle it is changed to a Hurricane Kick.
Sinister Scythe: More obvious once Mantis gets his Desperation Attack ready.
Stock Animal Behavior: His grab move greatly resembles that of a real life mantis' grab.
This Cannot Be!: When he goes down, Dark Mantis says, "I can't believe it!"
Vocal Dissonance: In the English version, he speaks in a deep-voiced Texan cowboy accent.

Earthrock Trilobyte

Insect Inhabiting Rich Mineral Deposits

"The minerals we mine here are essential to the development of space!"

Japanese Name: Earthrock Torirovich

A trilobyte-based Reploid who was in charge of the rare metal mine situated in North America, which has minerals essential to space development used by the Jakob Project. When he became a Maverick, Trilobyte instigated a rebellion in Metal Valley and gave the extracted minerals to Sigma.

Weapon: Crystal Wall/Rekkyoudan/Bound Blaster

Weakness: Squeeze Bomb/Juuhazan/Spiral Magnum

Voiced by: Kyouzou Kudou (JP), Randall Wiebe (EN)

Advancing Boss of Doom: His stage has a gigantic Mechaniloid chasing after you; you then have to beat it with a moving crane. After you damage it enough, it'll start running away from you.
Advancing Wall of Doom: For his Desperation Attack and at a certain point prior to his fight, Earthrock summons several crystal walls that attempt to crush players against the walls.
Ante Piece: After chasing the Metal Brontes into a warehouse, Trilobyte will briefly trap the Hunters in a small room and send a barrage of Crystal Walls.
Attack Reflector: What Zero will get from him; his normal slashes can reflect projectiles. Crystal Wall can also be used this way.
Big Creepy-Crawlies: He is a trilobyte robot.
Desperation Attack: Creates multiple advancing walls of doom when he Turns Red, just like one point during the level.
Gemstone Assault: Trilobyte utilizes gemstone-based attack in combat. His weapon, the Crystal Wall, also counts.
Heavily Armored Mook: You need to get rid of his armor or flip him over before you can properly damage him.
Logical Weakness: No amount of armor is going to be effective against a black hole that crushes even the toughest of defenses. His Crystal Wall however can block X's Squeeze Bomb.
Pinball Projectile: The Bound Blaster for Axl.
Proactive Boss: When you enter the place he worked at, this guy will create some Crystal Walls to crush the heroes against the doors.
Removable Shell: His armor can be destroyed with his weakness.
Smug Snake: Trilobyte is one of the eight New Generation Reploids that Sigma chose to usher in their new world, and rubs it into Axl's face for being a "half-baked prototype".
Sir Swears-a-Lot: Not quite profanity, but Trilobyte is not above calling the hunters with something synonymous to swearing, at least by robot standards.
Trilobyte: (To X) "Even a decaying pile of scrap like you can guess with that many hints, no?" ^note
Trilobyte: (To Zero) "You'll have to answer to my master sooner or later, you worthless pile of scrap!"^note
Trilobyte: (To Axl) "I don't suppose a half-baked prototype like you could guess what I'm getting at." ^note
The Social Darwinist: He has nothing but disdain for the old generation Reploids, calling them "old piles of scrap" or a variation every chance he gets.
Utility Weapon: A charged Crystal Wall can uncover hidden Rare Metal upgrades if used in the correct spot.

Gigabolt Man-O-War

High Voltage Drifter

"What? What's a Maverick? Do you know what it is?"

Japanese Name: Gigabolt Dokragen

A childish jellyfish-based new generation Reploid that supplied energy to Megalopolis. Following his transformation into a Maverick, he started causing chaos and siphoned off the energy supply of Megalopolis to Sigma. The Maverick Hunters are aware that his rampage would cause destruction, so they chase him through the city with a Sirius Ride Chaser to stop him.

Weapon: Thunder Dancer/Raikousen/Plasma Gun

Weakness: Crystal Wall/Rekkyoudan/Bound Blaster

Voiced by: Haruna Mima (JP), Mariette Sluyter (EN)

Boss-Only Level: Aside from traffic obstacles, Man-o-War himself is the only enemy found in the entire level. The Hunters must chase and shoot down his ship form until he finally gives up and face them in a proper battle.
Chain Lightning: Thunder Dancer can jump to closest enemies after it hits one.
Cloud Cuckoo Lander: His attack cries and death cry are the names of random objects, primarily food. Examples include "Tomato juice!" for his Thunder Dancer Desperation Attack, "Marzipan!" for his Plasma Gun attack, "Liver breath!" upon being hit (though that could be a swear word), and "Oh yeaaah!" (or "Cheese and rice!") for his Death Cry Echo.
Death from Above: His desperation move as he crashes lightning down on his enemies.
Deadly Lunge: What Zero will get from him. It's also electrically charged.
Desperation Attack: Causes a massive electric storm that hits certain points on the floor. X can completely neutralize this by putting up a Crystal Wall.
Electric Jellyfish: Not quite one (a Portuguese Man-of-war isn't a jellyfish, but looks similar), but the idea is there. In Japan, though, he is a jellyfish (Dokragen, in his Japanese name, is derived from "kurage", meaning jellyfish).
Electronic Speech Impediment: What the heroes will think of him the first time they meet him, seeing as he doesn't respond to their words the first time. They suspected that his mind has become broken. They may or may not be wrong.
Flunky Boss: During his chase and the main fight with him, Gigabolt can summon small jellyfish drones.
Flying Seafood Special: A flying jellyfish robot.
"Get Back Here!" Boss: In the level itself, you have to chase him down via a flying Ride Chaser and attack him.
Gratuitous English: All of his battle lines in the original Japanese dub are in english.
Lazy Bum: His bio in X Legacy Collection 2 mentions that he became bored and lazy at his position as an urban power supply.
Lightning Gun: Plasma Gun.
Logical Weakness: Some kinds of crystals act as conductors. In his battle, his Overdrive attack Thunder Dancer can actually be nullified by putting out a Crystal Wall to suck all the lightning up akin to a lightning rod.
Obliviously Evil: Even more than his peers; he really doesn't understand that what he's doing is wrong.
Platform Battle: A very small platform (by boss battle standards), at that.
Punny Name: His name is a mashup of "Giga-Volt" (a billion Volts of electricity) and "Thunderbolt" (a flash of lightning).
Rubber-Hose Limbs: His arms can stretch from the top of the screen to the edges of the platform, many times their default length. If he gets hit with the group's Double Attacks at this point, he will appear to have lost them.
Shock and Awe: He utilizes electric-based attacks.
Spell My Name With An S: He is called Gigavolt in cutscenes.
Transforming Mecha: He can fold his limbs into his body, giving him the appearance of a UFO.
Utility Weapon: His weapons can be used to power up the generator in Dark Mantis' level, lighting up the whole place.
Vocal Dissonance: He has a high-pitched voice and his (programmed) gender is male. Although, it could have been done to reflect his childish nature.

Gravity Antonion

Twister of Time and Space

"Maverick? Once again, you attach labels to me. What arrogance! Hmph. At any rate, if you choose to stand in my way, I'll crush you!"

Japanese Name: Gravitate Ant-Onion

An ant-based new generation Reploid who worked in an anti-gravity laboratory situated in northeast Australia. He was a very intelligent scientist, with a calm and polite demeanor. When he became a Maverick, he created a tower above the anti-gravity lab.

Weapon: Squeeze Bomb/Juuhazan/Spiral Magnum

Weakness: Shadow Runner/Rasetsusen/Black Arrow

Voiced by: Hayata Ishida (JP), Roger Rhodes (EN)

Ant Assault: He's a Maverick robot based on ant, and a Mad Scientist to boot.
Armor-Piercing Attack: All the Special Weapons gained from his defeat.
BFS: Antonion can make one out of blocks, though his version has him swing his BFS with the mandibles around his mouth. It is also the basis of Zero's Juuhazan, although Zero uses his hands to swing it, not his mouth.
Ceiling Cling: Justified as he's based off an ant.
Death From A Bove: When he Turns Red, he creates a shower of metal blocks that fall down.
Desperation Attack: Teleports away and creates multiple metal blocks that fall all over the arena.
Energy Absorption: His Squeeze Bomb can absorb most projectiles, making hitting him tricky. X can also use this.
Gravity Master: A gifted scientist specializing in gravitational forces.
Gravity Screw: His stage has this as its main gimmick (although it rotates to accomodate the new gravity to prevent an Interface Screw). He can also utilize this in his arena.
Ground Pound: Zero's Juuhazan is changed into this if he uses T-Breaker or K-Knuckle to perform it. He also performs it faster with those weapons.
Improvised Weapon: A BFS made out of those blocks in his stage.
Logical Weakness: Somewhat; as darkness has no weight (as it is the absence of light) and thus isn't affected by gravity (and the Squeeze Bomb). Alternately, the homing nature of Mantis' weapons are perfect for zeroing in on Antonion, who usually moves fast or burrows under the walls and ground/ceiling to appear in another place.
Mad Scientist: He apparently is one for anti-gravity technology.
The Paralyzer: Can shoot out green goo that immobilizes the player. Use Tag Assist to free yourself!
Pintsized Powerhouse: Despite his small size, Antonion can lift an object that is several times his size.
Red Is Violent: Antonion is a Maverick and his armour has a crimson hue.
Revolvers Are Just Better: Spiral Magnum. It can blast through walls, an ability that Axl's other weapons lack.
Spent Shells Shower: Spiral Magnum is the only one of Axl's weapons that do this. The closer you are to the enemy, the faster the shower become (because your firing rate becomes faster).
Stock Animal Behavior: Lifting a block that's bigger than him. Also walking on the ceiling and walls and swinging a BFS with mandibles instead of hands.
Strong Ants: Antonion can create large heavy blocks that are about four times his size, pick them up from underneath, and throw them at the player character!

Optic Sunflower

Assassin From the Depths of Outer Space

"That's where you're wrong. We may not be the good guys, but we're no monsters. Such concepts are beyond the grasp of halfwits like you."

Japanese Name: Optic Sunfloward

A sunflower-based Reploid who was originally responsible for running Troia Base, a virtual Hunter training facility stationed in Europe. When he became a Maverick, he caused the management program of the training area, "Helios", to go haywire.

Weapon: Shining Ray/Tenshouha/Ray Gun

Weakness: Green Spinner/Youdantotsu/Blast Launcher

Voiced by: "Turkey" (JP), Elinor Holt (EN)

Ax-Crazy: Though he claims not to be so. After you defeat at least four other Mavericks, his lines are rather normal in tone.
Chasing Your Tail: One of his attacks has him go into one point of the room and spin a laser around the battlefield, forcing the player to move in a circle.
Call-Back: If you face him as Zero after beating four other Mavericks.
Sunflower: "Zero, surely you've figured it out. You must have an inkling as to what we're after here."
Zero: "Hmph. How would I know anything about how you Mavericks think?"
Sunflower: "My master remembers you well. You had the chance to become the ultimate destroyer. That's ancient history now..."
Crosshair Aware: When Optic Sunflower prepares his Earth Crush, a harmless laser will follow your position...and then be followed up by a deadly one.
Death from Above: For his Desperation Attack when he drops to half HP, Optic Sunflower will call upon a Kill Sat to blast harmful lasers down from above.
Desperation Attack: His Earth Crush, where he creates a projection of satellite cannon and fires a massive laser from it.
Dude Looks Like a Lady: Optic Sunflower is sometimes mistaken as female due to his high-pitched voice and slender, flower design.
Kill Sat: His Overdrive. When performing it, an image of a satellite cannon can be seen.
Light 'em Up: Employs a lot of light-based weaponry.
Light Is Not Good: He is a light-themed sunflower Reploid, but is still a Maverick. When X uses the Shining Ray, he turns the trope on its head.
Logical Weakness: Plants use sunlight to grow and become stronger. This means Sunflower is weak to Green Spinner, even though he himself is a plant.^note
Pillar of Light: His Desperation Attack.
Pinball Projectile: He can fire a ball of light mesh that bounces off walls, ceilings, floor and platforms. It can trap you in if it hits you.
Plant Person: A sunflower-based humanoid robot.
Ray Gun: What Axl will get from him.
Self-Duplication: Can create fake clones of himself.
Spread Shot: Shining Ray shoots out a light projectile upwards that explodes outwardly like fireworks, especially with the charged version.
Take Cover!: During his Chasing Your Tail move, there'll be a floating platform (placed at random points) that can block the laser, allowing you to cover yourself.
Teleport Spam: He frequently teleports in battle.
Wave-Motion Gun: His Earth Crush attack.
Vocal Dissonance: His voice sounds somewhat like a woman's.
