open/close all folders

Kirby's Adventure/Nightmare in Dream Land

Mr. Tick-Tock

A living alarm clock mini-boss that attacks by launching music notes and making short-ranged sound waves. Gives the Mike ability.

Animate Inanimate Object: A living alarm clock with hands, feet and face.
Big Ol' Eyebrows: Has prominent eyebrows that also double as clock hands.
The Bus Came Back: Returns in Super Star Ultra after only being present in Adventure and its remake.
The Cameo: Appears as a drawing in Canvas Curse's sub-game, Paint Panic.
Musical Assassin: Both of his attacks involve weaponizing his alarm.
Music Is Eighth Notes: The notes that he throws out tend to be eighth notes.
Our Monsters Are Weird: He's essentially a sentient alarm clock with a moustache.
Ring-Ring-CRUNCH!: It's possible to attack and even defeat him while he's ringing.

Rolling Turtle

An anthropomorphic turtle mini-boss that attacks with wrestling moves. Gives the Throw ability.

Chuck Cunningham Syndrome: Replaced by Phan Phan in future installments.
Green and Mean: He's a green boss.
Human Hammer-Throw: If he rolls into Kirby, he throws him around.
"Instant Death" Radius: If Kirby ever gets too close to the Rolling Turtle, he's asking to get tossed all around the stage.
Law of Chromatic Superiority: There's a red variant of the turtle in a hidden passage in Rainbow Resort. He's stronger than the usual green.
Rolling Attack: It's in the name.
Speedy Snail: Despite being, well, a turtle, his attacks are lightning-fast and difficult to dodge.

Phan Phan

A playful elephant-like mini-boss creature. Usually gives the Throw ability, but on occasion has given the Suplex ability.

Adaptational Heroism: In the games, Phan Phan is an especially difficult Mini-Boss who's ruthless and merciless towards Kirby and definitely not a friend of his. However, in the anime, he's instead a shy, benevolent Shrinking Violet and a friend to Kirby despite being made as a tool of evil.
Armless Biped: Only has two legs and no arms, but his trunk substitutes for them.
Badass Adorable: A cute elephant who happens to be a dangerous Mini-Boss.
Cruel Elephant: Don't let its cute appearance fool you; it's an antagonistic elephant that fights very viciously.
Edible Ammunition: Throws apples as his ranged attack.
Face of an Angel, Mind of a Demon: He's cute, but is still a boss.
Human Hammer-Throw: Throws Kirby over its head after grabbing him, sometimes spins him around first.
Psycho Pink: A male instance; he has pink toenails and is a boss.
Rolling Attack: One that doesn't run over Kirby but rather grabs him mid-roll.
Shout-Out: One of Phan Phan's Palette Swaps in Nightmare in Dream Land looks just like Phanpy.
Suspiciously Similar Substitute: Replaces Rolling Turtle in Nightmare In Dream Land.

Fire Lion

A mini-boss lion mastering the power of flames. Usually gives the Burning ability, but if Burning is unavailable he’ll give the Fire ability instead.

Amazing Technicolor Wildlife: His original design in Kirby's Adventure was simply a blue lion with a white mane. Nightmare in Dream Land makes him look more like an Elemental Embodiment of fire in the shape of a lion.
Bullfight Boss: He can be stunned by having him charge into a wall.
Burn Baby Burn: In the anime, Nightmare uses his flames to burn up his garbage.
The Bus Came Back: He returns in Super Star Ultra after only being present in Adventure and its remake
The Cameo: He appears as a sticker in Planet Robobot.
Dual Boss: In the final level of Super Star Ultra, Dedede sics two of them at Kirby.
Evil Is Burning Hot: He's constantly on fire and can engulf himself in it when he's charging at you.
Fiery Lion: A lion with a mane and tail tuft made out of fire, which uses a combination of Natural Weapons and fire attacks against Kirby.
Grapple Move: He may sometimes try to grab Kirby; if he hits, he'll then claw Kirby repeatedly for high damage.
Non-Standard Character Design: Most Kirby characters are cute and simple-looking Cartoon Creatures but Fire Lion stands out for looking a lot more realistic by comparison. He wouldn't look so out of place in an RPG rather than a Kirby game.
Playing with Fire: Surprisingly only used when he charges at you, in which he engulfs himself in flames.
Technicolor Fire: When he's fought later in the game, his mane is made of a strange purplish fire instead of the usual red and orange. In Super Star Ultra, if you pause the game at the right moment, you can see this is accomplished by rapidly swapping between his normal palette and a palette with blue flames.
Wreathed in Flames: One of his signature attacks is a fiery ramming tackle.

Heavy Mole

A large, one-eyed, brass robot that tunnels under the ground, and the boss of Yogurt Yard. Kirby follows and fights it from behind as it works through the dirt with its saw-like appendages and mouth.

Auto-Scrolling Level: The gimmick of the fight is that Kirby has to follow it as it tunnels, which depending on where it goes, can lead to Bottomless Pits, or Kirby getting crushed if the player isn't careful.
The Cameo: Appears as a keychain in Triple Deluxe.
Cyber Cyclops: It's a huge tunnelling machine with one big eye. The missiles it fires at Kirby, by virtue of being one-eyed drill-like projectile enemies, also count.
Dub Name Change: Not Heavy Mole, but its projectiles were simply called "drill-type bullets" in Japanese.
Flunky Boss: Fires off projectiles as an attack. Brown ones give the hammer ability, while red ones give Sleep, which, considering the nature of the fight, can be a death sentence.
Hidden Depths: A rare, non-positive example combined with a Pun — according to Kirby's Avalanche, Heavy Mole is a powerful Underworld figure who's known for underhanded tactics.
Logical Weakness: A big machine like Heavy Mole would naturally heat up fairly quick and have to vent itself out at some point. Naturally, these points are where it slows down to cool and gives Kirby an easy chance of catching up and attacking.
Poison Mushroom: If Kirby inhales the red missile expecting to receive the extremely powerful Hammer ability, he'll get the Sleep ability instead. Considering that Heavy Mole is constantly burrowing through the arena, this can drop Kirby into a Bottomless Pit or get him crushed.
Spikes of Villainy: It's covered in spikes, and it's one of the villainous bosses Kirby faces in both Kirby's Adventure and Kirby's Avalanche.
This Is a Drill: Heavy Mole's missiles drill through the air after Kirby. In Japanese, they're even called "drill-type bullets".
Tunnel King: Specializes in creating tunnels underground.

Kirby's Dream Land 2

Efreeti

A strange black creature that can manipulate fire. Gives the Burning ability.

Bullfight Boss: Engulfs itself in fire and shoots itself towards Kirby.
Chuck Cunningham Syndrome: Replaced by Boboo in Dream Land 3.
Dark Is Evil: A boss who's mainly colored black.
Evil Is Burning Hot: It can engulf itself in flames, gives the Burning ability when swallowed, and is evil.
Playing with Fire: It can surround itself in fire.
Red and Black and Evil All Over: Most of its body is black, it has reddish shoes, and it's evil.
Yellow Eyes of Sneakiness: Contrasting with its black body.

Jumpershoot

An umbrella with one foot, one eye, and a mouth. The only mini-boss to date that gives the Parasol ability.

Karakasa: It's based on one.
King Mook: It's a giant Drifter, though it has more body parts than its enemy counterparts.
Maniac Tongue: A boss who sticks out its tongue just 'cuz.
Shoe Slap: One of its attacks is kicking its geta at you. Kirby can inhale it to spit back at it.
Spell My Name With An S: It's Jumpershoot in Dream Land 2 and Jumper Shoot in Dream Land 3.

Master Green

A big jellyfish imbued with electricity. Gives the Spark ability.

Chuck Cunningham Syndrome: Makes no appearances in Dream Land 3, nor is there any Spark ability miniboss in that game to replace it.
Electric Jellyfish: It's a large jellyfish that uses electricity to attack.
Green and Mean: Its name appears to involve this, yet the official artwork averts this by coloring him yellow. Its later appearances play this straight, however, by actually making him green. He's also a boss.
Non-Indicative Name: Master Green is colored yellow. Averted with its appearances in the unaired "Kirby of the Stars" pilot and Kirby 25th Anniversary Twitter artwork, where it is depicted as actually being green.
Shock and Awe: Uses electrical attacks and gives the Spark ability.

Captain Stitch

A large Gordo as a miniboss. Invincible as long as he has his spikes. Gives the Needle ability.

King Mook: Of the Gordos.
Nigh-Invulnerability: Just like a regular Gordo… until he sheds his spikes.
Spike Balls of Doom: What he basically is. With a pair of eyes.
Spike Shooter: He can shoot out his spikes as projectiles.
Spikes of Villainy: He has multiple spikes and he's evil.
Tactical Suicide Boss: He'd be invincible if he didn't do things that deprived him of his spikes.

Waiu

A humanoid ninja that throws cutter projectiles. Gives the Cutter ability.

The Cameo: Summoned as one of Adeleine's paintings in Kirby Star Allies.
Ninja: Though he doesn't give the Ninja ability.
Purple Is Powerful: He's dressed in purple ninja garb.
Yellow Eyes of Sneakiness: The only visible parts of his face.

Nruff & Nelly

https://static.tvtropes.org/pmwiki/pub/images/kdl2_nruff.png

A large wild boar and boss of Big Forest, Nruff runs across a series of dilapidated bridges hung between a pair of hollowed out trees with her minions, the smaller Nellys.

The Cameo:
- In the anime, they can be seen alongside other woodland creatures.
- They appear as a keychain in Triple Deluxe.
Composite Character: Nruff became more like Nelly after their first major appearance, gaining the juvenile back markings and losing the tusks, but keeping the eyes and name.
Dash Attack: Runs wildly around to attack Kirby.
Degraded Boss: Nruff at first is the boss of Big Forest in Kirby's Dream Land 2. She became a normal enemy afterwards, sometimes being a mount for Waddle Dees.
Eyes Always Shut: For some reason, Nruff's eyes are like this.
Flunky Boss: The Nellys follow Nruff around to serve as ammo for Kirby.
Full-Boar Action: One of the earliest examples in video games at that, being a boar that's antagonistic to Kirby.
Mad Bomber: She occasionally tosses bombs.
Monster Is a Mommy: According to the official Kirby Twitter, an illustration for Mother's Day 2019 suggests that she is the mother of the Nellys she appears with.
Turns Red: After getting down to half health, Nruff begins mixing up her charging, and actively jumps from bridge to bridge mid-charge to confuse the player.

Sweet Stuff

An aquatic angler fish with a lightbulb on its head, with can fire lightning bolts. It is fought as the boss of Ripple Field.

The Bus Came Back: It reappears as a boss in Kirby Mass Attack's Kirby Quest sub-game.
Degraded Boss: It's one of the bosses that Adeleine draws in Dream Land 3, and it can be defeated in less amount of hits. It also bounces around as the fight isn't underwater.
Flunky Boss: In Kirby's Dream Land 2, it is aided by Squishies and cyclopian starfish called Tincells; in Mass Attack, it's aided by a Squishy and a Flotzo.
Punny Name: Possibly; anglerfish is called "ankou" in Japanese, which sounds the same as the word for sweet bean jelly, i.e "sweet stuff". The very name also is fitting for someone who tries to lure their prey.
Shock and Awe: It fires sparks from its lure.
Underwater Boss Battle: Its entire boss fight takes place underwater.
Wake-Up Call Boss: It provides more of a challenge to players who aren't used to underwater physics.

Kirby Super Star/Kirby Super Star Ultra

Iron Mam

An armored female miniboss creature with the shape of an egg. Gives the Fighter ability.

Blush Stickers: Has pink blush on her cheeks, similarly to Kirby.
The Cameo: Appears in Triple Deluxe as a keychain.
Cute Bruiser: She wears an adorable pink bow and has a cute face, but she gives the Fighter ability and attacks with punches.
Mighty Glacier: Moves rather slowly, but gives mean punches.
No Mouth: Doesn't seem to have any mouth (though it may be just hidden under armor).
Psycho Pink: She's an antagonistic fighter with some pink.
Punny Name: Her name sounds like a certain armored superhero.
Rocket Punch: Mainly attacks by launching her ball-fists forward.
Shoulders of Doom: Complete with Spikes of Villainy.
Spear Counterpart: A (presumably) male variant of her appears as an opponent in the Megaton Punch minigame.
Spell My Name With An S: Iron Mom became Iron Mam as of Super Star Ultra.
Tertiary Sexual Characteristics: Has a pink bow on her head.

Jukid

A martial artist miniboss with a pair of expandable, floating hands. Is one of the few sources of the Suplex ability alongside Bugzzy.

Delinquent Hair: Sports a blonde mohawk.
No Mouth: He doesn't seem to have any mouth.
Psycho Pink: A male variant as he has some pink and he fights you.
Punny Name: From "Judo + Kid"
Rocket Punch: In a variant, he can send his hand to a distance to grab Kirby to judo-throw him.

Fatty Whale

A large blue whale in a sailor suit. He's fought in the Great Cave Offensive and is the boss of Aquarius/Aqualiss in Milky Way Wishes.

Acrofatic: He is a large physical fighter that performs some impressive jumps.
Blown Upward by a Blowhole: Many of his attacks involves shooting high-pressure water out of his blowhole.
Bouncing Battler: Two of his moves consist of him bouncing multiple times sideways.
Clothing Damage: His defeat sprite in Super Star Ultra shows his attire in tatters.
Collapsing Ceiling Boss:
- When he shoots water from his blowhole, rocks and Blippers fall from the ceiling onto the arena.
- After performing his tidal wave attack, more rocks will fall from the ceiling.
Distinguished Gentleman's Pipe: One of the few tobacco references in Kirby.
Fat Bastard: He's a big and fat whale who's a boss.
Half-Dressed Cartoon Animal: He only wears the top portion of a Sailor Fuku. Justified, as he's a whale and wouldn't be able to swim properly in a pair of pants.
Limited Animation: In the original Kirby Super Star, he is only composed of three sprites, which are rotated and/or stretched during attacks. The DS remake adds in more sprites.
Making a Splash: He can spit a torrent of water from his blowhole (like most whales do) that can hurt Kirby. His heavy splashing also causes a huge water wave to engulf the screen, although this does not do damage and only blows Kirby upwards.
Mighty Glacier: Appropriately for his size, he's slow and powerful, although certain moves can be deceptively fast.
Monster Whale: A massive whale who uses his girth as an effective weapon, either to create tidal waves or to crush his enemies.
Sailor Fuku: Not quite the "school uniform" version of the trope, but he's still dressed like a sailor.
Waterfront Boss Battle: Fatty Whale attacks either by bouncing atop the floating platform Kirby's standing on or by swimming around said platform while attacking.
Wingding Eyes: His eyes turn into stars when defeated in Super Star Ultra.

Computer Virus

Some strange surreal entity that acts as a parody of turn-based role-playing games. Appears as the second boss of Great Cave Offensive and Planet Halfmoon's boss in Milky Way Wishes.

Absurdly Sharp Claws: The Red Dragon/Great Dragon has a slashing attack that takes the form of a spread of spinning discs.
Adaptation Name Change: In Ultra, the Dancing Doll becomes the Puppet, the Witch becomes the Magician, and the Red Dragon becomes the Great Dragon (the last change makes the most sense, since Ultra recolors the dragon to be orange and, later on, purple).
Black Knight: In "Helper to Hero", the Evil Knight has black armor.
Blob Monster: Its Slime form is a green goo monster.
Blow You Away: The Red Dragon/Great Dragon can flap its wings to attack, as well as blowing Kirby backward.
Breath Weapon: The Red Dragon/Great Dragon can breath fire.
Computer Virus: Not exactly; it's more of a game program that happens to be running in Kirby's reality, not a malicious piece of software. This was the result of a Dub Name Change.
Defend Command: The Witch/Magician, Evil Knight, and Red Dragon/Great Dragon can spend their turn guarding (by casting a protection spell, raising its shield, and petrifying itself, respectively). This heavily reduces damage done to them, but it also stops them from attacking for a turn.
Disc-One Final Boss: Initially seems to be the end-boss of "Milky Way Wishes" (it's the boss of Planet Halfmoon, which is intended to be the final planet Kirby visits), but Marx hijacks the plot directly afterwards.
Dub Name Change: It was called "Battle Windows" in Japanese and Korean, which was more descriptive of the boss, but ran the risk of possibly being confused with the more well-known Windows. In Ultra particularly, Great Dragon is called "Grand Dragon" in Japanese and Korean, which is also the epithet of the leader of the Ku Klux Klan in the States.
Evil Is Burning Hot: The Red Dragon/Great Dragon can attack you via breathing fire.
Evil Is Deathly Cold: Both the Evil Knight and Magician/The Witch play this straight; the former can use a freezing slash while the latter can attack with an ice spell.
Flechette Storm: The Evil Knight can attack by throwing knives, which manifests as knife projectiles raining from the ceiling.
Giant Space Flea from Nowhere: It pops up out of nowhere in "The Great Cave Offensive" as Kirby moves from one area to the next. Its appearance in "Milky Way Wishes" makes slightly more sense, since Planet Halfmoon is a surreal place.
Green and Mean: Only played straight with Slime, an evil-doer that's mainly colored green.
An Ice Person: The Witch/Magician has an ice spell, and the Evil Knight has a freezing slash.
Mook Chivalry: Justified by the implementation of RPG mechanics; Computer Virus is the only boss in the game that attacks just once at a time and gives you free time to attack it back. It even provides you with Copy Essences!
Nonstandard Character Design: Most of its forms are either more realistic-looking or more humanoid than the typical Kirby style. Unlike other bosses, they have Limited Animation with only three or so different sprites each. And, well, no other bosses in any Kirby game is a computer program, much less the way this boss looks and fights.
Obviously Evil: The Evil Knight has it in its name, as well as its outfit of a horned, skull-like helmet and a skull-bearing shield.
Our Dragons Are Different: Compared to the Ice Dragon, the Red Dragon/Great Dragon is a much more traditional portrayal of the creature.
Perverse Puppet: It has a Dancing Doll/Puppet form, though it's no more threatening than the Slime.
Playing with Fire: The Witch/Magician has a fire spell, and the Red Dragon/Great Dragon has fire breath.
The Points Mean Nothing: After Kirby (or Meta Knight) defeats all the monsters it has to offer, it'll dole out some fake Experience Points and stat boosts while its windows close. Not the case in the Boss Rush modes, where it simply closes immediately.
Purple Is Powerful: The Magician and Great Dragon in Milky Way Wishes and Helper to Hero are colored purple, and the strongest incarnation of them. Subverted with the Evil Knight, as it starts with purple in his weaker form and turns black in his stronger form.
Razor Wind: The Red Dragon/Great Dragon's wing attack sends out wind slashes that damage Kirby, but the slashes can be broken with attacks or even inhaled.
Red Is Violent: Several of its forms have at least some red, and they all can attack you. This especially applies to the Red Dragon.
Retraux: Its battle theme is an 8-bit remix of the usual boss battle theme in the game, to capture the "retro RPG" feel.
RPG Elements: The whole boss is a parody of it, with the battle turning into a "turn-based" one, a text box at the top saying about what's happening, and after the battle, you get "EXP" and "stat points" (not that they matter).
Shows Damage: The description window will tell you how much damage the player deals at the enemy.
Sinister Scimitar: The Evil Knight uses a curved sword, and is, well, evil.
Stationary Boss: The different foes summoned by the Computer Virus stay completely still, only moving when they lower down from the window they're in to be attacked.
Status Buff: The Evil Knight can "store up power", making his next attack more powerful.
Sudden Game Interface: Computer Virus forms a game inside the game, consisting of three windows that display the current enemy, a health counter for the enemy, and descriptive battle text.
Sword Beam: When the Evil Knight "brings his sword down", a crescent flies out of it to strike the player character.
Turns Red: Subtle, but their attacks are usually more intense when their health goes low.
Unique Enemy: The Slime and Dancing Doll/Puppet are only fought in "The Great Cave Offensive" (both the mode itself and when Meta Knight runs through it in "Meta Knightmare Returns"). The Arena versions of the fight use the version from "Milky Way Wishes" with the Evil Knight and Red Dragon/Great Dragon.
Wind from Beneath My Wings: The Red Dragon/Great Dragon's wing-flap attack pushes the player towards the right of the screen.
Wizard Classic: Its Witch/Magician form resembles this.
Zero-Effort Boss: Its Slime and Dancing Doll/Puppet forms only occasionally attack with a star shot (which can be blocked for no damage) and otherwise waste their turns with pointless actions. Its other three forms put up a bigger fight.

Chameleo Arm

A chameleon-like foe that can change color at will. It appears in the Great Cave Offensive and Planet Hotbeat of Milky Way Wishes, and is one of the few enemies with a means of gaining the Paint ability.

Adaptation Name Change: In the SNES version of Super Star, he was named Ghameleo Arm, which was closer to his Japanese name. Ultra went ahead and changed the G into a C in English.
Death Throws: When he's defeated, he falls off the screen with a shocked, wide-mouth look on his face.
Hollywood Chameleon: Freely changes color after becoming visible.
Just Eat Him: He can eat Kirby or his Helper by pulling them in with his tongue, which he follows by spitting them into a wall.
Logical Weakness: The Paint ability, which can be absorbed from his paint globs, both deals heavy damage to him and removes his invisibility by splattering him with color. He can still go invisible after this, however.
Multiple-Tailed Beast: He has two tails.
Multipurpose Tongue: He uses his tongue to grab and eat Kirby/his Helper, though it's only involved in one attack of his.
Prehensile Tail: He can stretch out his tail to grip onto the walls of his room.
Rolling Attack: He curls up and rolls along the floor as a ground attack.
Rubber Man: His double-tail stretches out pretty far, which he uses in a few attacks by either extending it outwards (which he may or may not follow by pulling himself towards where his tail goes) or by pushing his body downwards while hanging from it.
Skippable Boss: The Old Tower area of "The Great Cave Offensive" is completely optional to explore, so you only need to fight Chameleo Arm there if you're collecting all the treasures. No matter what, however, you still have to fight him on Hotbeat in "Milky Way Wishes".
Visible Invisibility: Periodically goes invisible, but you can track him by looking for background distortions.
Wall Crawl: He can jump up and then cling to the background wall.

Wham Bam Rock

Click ^here to see his original design.

A Flying Face with rocks for hands. He serves as the Final Boss of The Great Cave Offensive. It is also the boss of Cavios in Milky Way Wishes.

Battle Theme Music: In Ultra, he shares the Castle Lololo theme with Dyna Blade and Wham Bam Jewel (in the original, he had the normal boss theme).
Blackface-Style Caricature: His original appearance had giant, bulbous orange lips, and while he has no skin, he appears on a black backdrop. As such, his appearance was changed in Ultra and Wham Bam Jewel's lips are far thinner than Rock's original appearance.
The Cameo: Appears in Return to Dream Land as one of Stone's forms, and in Team Kirby Clash Deluxe as one of the equipments for Hammer Lord.
Death from Above: Most frequently by slamming his fist, and later palm, onto the player character. Also snaps his fingers to summon rocks that fall down, and makes his stone fingers fall down one by one.
Dishing Out Dirt: His hands are made of stones, which he can drop on Kirby. They can be inhaled for the Stone Ability as well.
Final Boss: Of the Great Cave Offensive.
Giant Hands of Doom: Most of his attacks would later be used by Master Hand.
Grapple Move: He can attempt to grab Kirby/the Helper/Meta Knight with his hand, then crush them with his fingers slowly. Mash buttons to escape!
Megaton Punch: Has a punching attack that sends Kirby to the opposite wall.
Same Character, But Different: His face was different in the original Super Star (think Mr. Popo) before it somehow changes into a Mayincatec-like face that looks more rocky. The hand is still the same, however.^note
Trick Boss: Is set up to be the Final Boss of Helper to Hero, only to have Wham Bam Jewel to follow.

Twin Woods

A pair of sentient trees that share an appearance and abilities with Whispy Woods. They are fought in Revenge of Meta Knight as well as the planet Floria in Milky Way Wishes.

Blow You Away: They shoot air shots out of their mouths.
Boss Subtitles: "Giant Tree Twins, Twin Woods" in Kirby Fighters 2.
The Bus Came Back: They return in Kirby Fighters 2 after a long absence.
Death from Above: By dropping apples, just like Whispy Woods. They can also drop Gordos and bugs. In Kirby Fighters 2, they throw in more attacks, such as dropping explosive fruits and giant apples, or even leaping up and trying to crush their foes with their weight.
Detachment Combat: Unlike regular Whispy, Twin Woods can swap pieces of their trunks.
Dual Boss: Right in the name. Defeating one tree allows the player to focus on the other.
Sequential Boss: In Revenge of Meta Knight, they are immediately fought after defeating Whispy (again).
Warm-Up Boss: They're the first boss in Milky Way Wishes.
When Trees Attack: Hostile trees just like Whispy, except there's two of them.

Heavy Lobster

"This time, we will succeed! Heavy Lobster, away!"

—Captain Vul

A lobster-like robot serving under Meta Knight, tasked with guarding the Halberd. Another version of the robot also appears in Planet Mecheye in Milky Way Wishes.

Adaptational Villainy: In the anime. It is one of Nightmare's monsters and is sent out to destroy the Halberd as the Climax Boss in the penultimate episode.
Animal Mecha: A giant, lobster-shaped robot.
Battle Theme Music: In its second encounter in Revenge of Meta Knight (only in Ultra), this theme plays. It also plays during its battles in Milky Way Wishes, The Arena, and Helper to Hero.
The Cameo: It appears as a Keychain in Triple Deluxe and as a Spirit in Super Smash Bros. Ultimate.
Confusion Fu: Heavy Lobster will frequently bounce around, dash forwards at high speeds, and pick from one of several different attacks to launch from its claws. This gives it a level of unpredictability that makes it especially dangerous.
Fire-Breathing Weapon: Comes equipped with a flamethrower in its claws.
Flunky Boss: Can deploy a smaller lobster robot and a living slime-like enemy. The latter can be inhaled for the Paint ability.
Giant Enemy Crab: And a mechanical one, at that!
A Handful for an Eye: The Paint ability will blind it, causing it to act even more erratically- to the horror of the crew.
Interface Screw: In Mass Attack, touching his paint globs will cause part of the screen to be splattered with paint.
The Juggernaut: When deployed after Kirby, it walks right through the Halberd's walls, smashing everything with ease.
Lightning Bruiser: While it doesn't have a particularly fast walking speed, Heavy Lobster can easily outrun Kirby by jumping, sprinting, and rocketing around.
Macross Missile Massacre: Downplayed: in Mass Attack (Kirby Brawlball sub-game), it only fires three, non-homing missiles at a time.
Red Eyes, Take Warning: Heavy Lobster's alternate color palette in Milky Way Wishes and Helper to Hero has a red eye, and it's hostile to Kirby.
A Taste of Their Own Medicine: Of sorts. One of Heavy Lobster's attacks involves using a paint blob. However, if you have the Paint ability (which can be gained by swallowing said blob), you can attack Heavy Lobster itself with paint.
Unexplained Recovery: At the beginning of the mode, it winds up being blown off the Halberd before Kirby can destroy it, yet it manages to return looking none the worse for wear near the end of the mode for round 2.
We Need a Distraction: When Kirby arrives at the Halberd for the first time, the crew sends Heavy Lobster to keep him busy while their ship is taking off, causing him and the robot to be blown away.

Combo Cannon

A two-in-one cannon that serves as the main armament of Battleship Halberd. It's also armed with a metallic claw on chains.

Adaptation Name Change: This happened twice — once in the 4Kids dub of the anime (where it was bizarrely called the "Gravity Disruptor") and again in Kirby Super Star Ultra (where it was called "Main Cannon #2"). The latter is considered a simple misinterpretation of the Japanese rendition (2連主砲), in which 「2連」 means double or twin and 「主砲」 means main or big gun; effectively Combo Cannon.
BFG: It's the Halberd's main gun. The top turret shoots big cannonballs while the bottom cannon shoots lasers. In Kirby Fighters Deluxe, a miniature version of the Combo Cannon (called Team Cannon) appears as one of the pick-up items (although it's still larger than Kirby). It normally just shoots small shots, but if a teammate mounts it together with you, the Kirbys can fire a devastating Wave-Motion Gun with it.
The Cameo: Appears in the background as a hazard in the recurring Battleship Halberd stage in the Super Smash Bros. games from Brawl onward.
Cognizant Limbs: The cannon's laser emitter can be destroyed separately from the boss itself. Its mechanical claw can also be destroyed, though it'll keep coming back.
Flunky Boss: In Epic Yarn a UFO periodically flies by and attacks.
Grapple Move: The chained claw can grab Kirby and either slam him to the ground, or hold him in front of the laser cannon.
Stationary Boss: Being an immobile turret.
Throw Down the Bomblet: The chained claw drops bombs every so often. They can be inhaled for the Bomb ability.
Wave-Motion Gun: The bottom cannon attacks with a large laser beam.

Halberd's Reactor

https://static.tvtropes.org/pmwiki/pub/images/halberd_reactor_kirby_superstar_ultra.png

The Reactor is the main engine that keeps the whole Halberd flying, and has similar defensive measures like the Combo Cannon.

Cores-and-Turrets Boss: Armed with three different types of turrets.
Fire-Breathing Weapon: Attacks with fire from both the floor and the cannon beneath it. In Epic Yarn it instead has two flame turrets that can block your Star Shooter's shots.
Flunky Boss: In Epic Yarn a UFO periodically flies by and attacks.
Living Battery: The Reactor is powered by a group of Wheelies that run back-and-forth non-stop, with the resulting energy being used for the rest of the ship. After its destruction, Wheelies escape, and one of them helps Kirby to flee the ship. As of Epic Yarn, it appears to be no longer using Wheelies as a power source.
Puzzle Boss: Kirby cannot attack it normally; he has to guide the Reflecting Laser turret to make its shots hit the reactor. Meta Knight, however, can use his Mach Tornado to take it down in one hit.
Reactor Boss: Destroying it causes the Halberd to begin sinking.
Stationary Boss: Being the Halberd's main power plant.
Tactical Suicide Boss: Can only be damaged with the reflecting lasers that it attacks Kirby with.

Wham Bam Jewel (Unmarked spoilers)

https://static.tvtropes.org/pmwiki/pub/images/whambamjewelkssu_9.png

A Flying Face with jewel-constructed hands, he knows more moves compared to Wham Bam Rock. Exclusive to the DS version, as it is the final boss of the Helper to Hero mode introduced in that version.

Battle Theme Music: He shares the Castle Lololo theme with Dyna Blade and Wham Bam Rock.
Cool Crown: Wears a bejeweled crown.
Death from Above: He has the same "fist/palm fall" and "falling rocks" move that Wham Bam Rock has.
Fangs Are Evil: He has prominent underbite fangs.
Final Boss: Of Helper to Hero.
Finger Gun: One of his attacks is to fire an energy blast from his finger. He can shoot consecutively as his health gets low.
Floating Limbs: Not just the hands. His whole face consists of separated parts floating within proximity of each other, as mentioned below.
Flying Face: Aside from the diamond hands, The True Arena intro cutscene reveals that Wham Bam Jewel's visible features are... actually his entire body.
Gemstone Assault: His hands are made of jewels, though Kirby will still gain the Stone ability if he inhales them.
Giant Hands of Doom: Just like Wham Bam Rock.
Grapple Move: In the same way as Wham Bam Rock.
King Mook: Literally. As his Flavor Text says, "he's the Wham Bam King"!
Megaton Punch: He can perform a more powerful version of Wham Bam Rock's punch where the fist flies across the screen while on fire.
Third Eye: No reason other than to make him look more creepy.
Throw Down the Bomblet: Unlike Wham Bam Rock, Wham Bam Jewel can drop exploding tiki heads. They can be inhaled for the Bomb ability.
Turns Red: Begins attacking faster as he loses his health. One immediate cue is when Jewel starts using open-handed slams, whereas he keeps his fists clenched when slamming at higher health.
Underground Monkey: He's a stronger version of Wham Bam Rock.
Upgraded Boss: Functionally, he's a version of Wham Bam Rock with more HP and new attacks.
Walking Spoiler: Absolutely nothing hints of his surprise appearance as the Final Boss of Helper to Hero, so all of his spoilers are unmarked.

Kirby's Dream Land 3

Yuki

A creature shaped like a snowman, who only appears in stages taking place in Iceberg. Gives the Ice ability.

Evil Is Deathly Cold: A snowman who gives the Ice ability and is a boss.
An Ice Person: Gives Ice ability when swallowed.
Meaningful Name: Yuki is the Japanese word for snow.
Off with His Head!: It sometimes knocks its own head off, though it always grows it back. It's vulnerable when it has its head.
Snowlems: It's a snowman.

Boboo

A living flame with eyes and feet. Gives the Burning ability.

Dash Attack: It attacks by shooting itself forward, leaving behind embers for Kirby to use against it when it crashes into a wall.
Evil Living Flames: Like its Bobo relatives, it's a living, malicious fireball with legs.
King Mook: It's a giant Bobo.
Playing with Fire: It is a living flame.
Suspiciously Similar Substitute: Of Efreeti from Kirby's Dream Land 2.
Waddling Head: A living fireball with a pair of blue feet.

Haboki

A giant broom mini-boss, with a face. Gives the Clean ability.

Animate Inanimate Object: A broom with a face.
Neat Freak: Being a living broom, it seems to have this mentality when sweeping the dust such as Kirby.

Acro

An orca that spits a variety of projectiles at Kirby. He is the boss of Ripple Field in Kirby's Dream Land 3 and the boss of Aqua Star in Kirby 64. Like the Ice Dragon, he's a native to the "Dark Matter" games.

Ambiguously Evil: In Kirby's Dream Land 3, Acro is a victim of possession from Dark Matter, so he cannot be described as evil in those circumstances. Kirby 64 doesn't specify if there's possession shenanigans going on once more, so Acro could very well be an enemy through his own volition.
Animal Gender-Bender: Has a short fin in his debut, although it seems to be more of a result of the game's cutesy, chibi art style rather than biology ignorance, since his fin is the correct shape in Kirby 64: The Crystal Shards.
Brainwashed and Crazy: By Dark Matter in Dream Land 3.
Defeat Means Friendship: Collecting all the Heart Stars in Ripple Field in Kirby's Dream Land 3 will free him from Dark Matter's control, and he will be friendly the next time Kirby enters his arena.
Devious Dolphins: An antagonistic orca, although he's normally docile unless he's possessed.
Dishing Out Dirt:
- In Kirby's Dream Land 3, his main attack in the first half of the battle is to slam into one of the cave walls, launching a boulder that Kirby can use against him. In the second half, he will slam into a wall to create an underwater avalanche.
- In Kirby 64, he can perform an underwater backflip and crash into the ground, creating two rocks between him that can be inhaled and spat back.
Flunky Boss: Spawns Acro Jr.s in Dream Land 3, and Fishbones in Crystal Shards.
Meaningful Name: Aside from being "Orca" backwards, "Acro" is actually a reference to his underwater acrobatics.
Robot Me: Mech Acro obstacles appear in Planet Robobot.
Sdrawkcab Name: "Orca" backwards.
Sequential Boss: The fight in Kirby 64 is fought in two phases — phase 1 plays similarly to the second half of his battle in Kirby's Dream Land 3, while phase 2 is an automatic upward scrolling segment as Acro chases Kirby to the surface.
Spell My Name With An S: Akro the Whale in the Dream Land 3 manual.
Spike Balls of Doom: In Kirby 64, he can sometimes spit out Gordos.
Super Spit: His main ability is to spit out various projectiles at Kirby, whether it's anchors, human skulls, or torpedoes.
Tailfin Walking: In the first half of his battle in Kirby's Dream Land 3, he can move on land with his tail.
Underwater Boss Battle: In Kirby's Dream Land 3, the first part of the battle starts off on land until he takes enough damage, then he destroys the floor to shift the battle into water. In Kirby 64, his entire fight takes place underwater.

Pon & Con

https://static.tvtropes.org/pmwiki/pub/images/pon_and_con_9.png

A duo of a tanuki (Pon) and a kitsune (Con), or alternatively a raccoon and fox. They get possessed by Dark Matter in Dream Land 3 and fight Kirby at the end of Sand Canyon. After being freed, they vanished from the series for a long time before being unwillingly recruited as Jambastion's guards in Kirby Star Allies.

Armor Is Useless: They're dressed in guard armor adorned with Jambastion's sigil in Star Allies, though it doesn't offer them any extra defense.
Boss Subtitles: They get the title of "Dual Defenders" in Star Allies.
Brainwashed and Crazy: First by Dark Matter in Dream Land 3, then once again by Jambastion's magic in Star Allies.
The Bus Came Back: Originally two of the most neglected characters in the franchise's history with just one game to their name… until Star Allies reintroduced them as significant bosses.
The Cameo:
- In the anime, they can sometimes be seen alongside the other woodland creatures.
- They get a keychain in Kirby: Triple Deluxe.
- In Kirby and the Rainbow Curse, they appear in one of Elline's diary entries about TV shows; apparently they've decided to do comedy specials, complete with bow ties and bowler hats.
Clean Dub Name: Con is renamed "Cot" in the French translation because "con" is a vulgar way to call someone an idiot in French.
Cunning Like a Fox: Con is a fox/kitsune who fights Kirby, though he's normally docile unless possessed by something.
Defeat Means Friendship: Played with in Dream Land 3; they only become good after you collected all the Heart Stars in Sand Canyon. In Star Allies, after they're defeated, you can throw a Friend Heart at them to make them open the Jambastion's gate for you.
Dual Boss: The lone two-enemy boss fight in Dream Land 3; despite having the same health bar, they each have their own health that must be depleted. Star Allies keeps this — if you focus on one, you can knock him out of the fight early.
Eyes Always Shut: Appropriately for a kitsune, Con's eyes are slanted and closed.
Lost in Translation: The English manual refers to them as just a raccoon and fox, since the mythological significance is lost outside of Japan.
Mad Bomber: For unknown reasons, big skull-marked bombs fall from the sky during their fight. Star Allies reveals that it's their mini mooks that do it.
Mini Mook: They're trailed by miniature raccoons and foxes (and sometimes a Waddle Doo in Star Allies), which may or may not be their children. They serve as Kirby's ammo should he lack an ability.
Rascally Raccoon: Pon is a raccoon/tanuki who fights Kirby, though like Con, he's friendly when not possessed.
Suspiciously Similar Substitute: The equivalent of both Lololo & Lalala and Nruff & Nelly for Dream Land 3, as they're fought as a pair, they rush back and forth along the arena, and they bring along smaller, inhaleable animals, similar to how Nruff is aided by her Nellys.
Youkai: Pon is a tanuki and Con is a kitsune, though they don't display any mystical powers related to their species. Averted in the English localization, where they're just a raccoon and fox.

Kirby Super Star Stacker

Gryll

Debut: Kirby's Super Star Stacker

"Hey hey hey! Are you truly so strong? I'm gonna give it a try!"

The Final Boss of the SNES version of Kirby's Star Stacker, who roams the outer space looking for the planets' best Star Stacker to challenge them — and whose attention turns towards Popstar and Kirby.

Ambiguous Gender: Their gender is never specified; while Gryll looks feminine at first glance, they also use the masculine "boku-chin" to refer to themselves, and a Kirby: Triple Deluxe Miiverse post does not count Gryll among the series' female final bosses.
Broomstick Quarterstaff: They can use their broomstick to thwack Kirby on the head.
The Cameo:
- Cameos in Planet Robobot as a rare sticker.
- Also cameos in Star Allies as one of the Stone's forms, alongside Brobo of Kirby's Block Ball.
Cute Witch: Looks like one, complete with the typical witch hat and Flying Broomstick.
Spirited Competitor: Gryll is looking for a challenge across multiple planets and is notably the only final boss to not be a bad person^note. This is reflected in the "Bad Boss Brothers" celebration picture in ''VideoGame/KirbyStarAllies'', which depicts all the series' final bosses up to that point; Gryll is the closest to Popstar next to [[TheAtoner King Dedede.
True Final Boss: Gryll only comes up if you manage to beat all opponents in the story mode without continuing.

Kirby 64: The Crystal Shards

Pix

https://static.tvtropes.org/pmwiki/pub/images/pix.png

A strange trio of diamond-like objects that appear and fight Kirby one by one on an elevator, before being fought properly at a high point of Rock Star's pyramid-like spaceship.

Chromatic Arrangement: Each one is colored after the primary colors of light.
Elevator Action Sequence: They're first fought while Kirby is ascending an elevator.
Laser Cutter: They can fire lasers that they sweep around, forcing Kirby to jump.
Puzzle Boss: Downplayed — during the battle, there'll be some "atomic structures" with different colors that Kirby can inhale; for instance, if Kirby shoots the red atoms to Pix's red crystal, it'll go down in two strikes, otherwise four.
Sinister Geometry: They are hostile octahedrons.
Wolfpack Boss: You fight all three of them at once.

Magman

A large being made entirely out of magma that's fought inside Neo Star's active volcano.

Advancing Boss of Doom: Very briefly chases Kirby once he starts his second phase.
Background Boss: Uses lava tentacles to attack Kirby for the first half.
Blob Monster: Blob of magma, that is.
The Cameo: In Triple Deluxe, Pyribbit can create lava pillars with faces on them that somewhat resemble Magman.
Evil Is Burning Hot: He attacks with magma and is composed of the stuff.
Flunky Boss: Summons Burnises during the second phase.
Living Lava: He's a creature made of magma.

^{Click here to see HR-E}

A bizarre lighthouse-shaped robot fought above the abandoned city on Shiver Star.

Advancing Boss of Doom: It chases Kirby during its second phase.
Background Boss: in the first phase.
Cyber Cyclops: Only during its first form. It can use Eye Beams to sweep across the area.
Giant Enemy Crab: Its HR-E form is vaguely lobster-like.
Macross Missile Massacre: Downplayed. It attacks by launching four small missiles during the first half, then attacks with one larger one during the second half.
Sequential Boss: After you deplete its health, it transforms into HR-E and gains a new health bar immediately after.
Time-Limit Boss: The platform HR-E chases you across isn't endless, though you'd have to actively trying to take that long.
Transforming Mecha: Goes from the humanoid HR-H to the snowmobile-like vehicle HR-E.

Kirby Tilt 'n' Tumble

Orbservor

A common name used to refer to cycloptic spherical creatures who appear as bosses in nearly every level in the game.

Go for the Eye: Their weak point is, you guessed it right, the eye.
Oculothorax: They are spheres with nothing more than a single eye.
Palette Swap: They all have different palettes depending on the level. The Orbservor in Level 1 has a green and yellow color palette. The one in Level 2 has a brown palette. The ones in Levels 4 and 7 are grey. The one in Level 5 is blue.
Punny Name: They are orbs with one eye with which they observe, hence Orbservors.

Tertiary Sexual Characteristics: wears a ribbon on her head, which is derived from gift box ribbons.
Unique Enemy: After completing the Ghost Medal in Squeak Squad, which will replace all of her miniboss appearances with Tedhaun, except for one level in Secret Sea.

Warm-Up Boss: Stays in one place and can be defeated in seconds with the Hammer, Stone, or Smash abilities.

Deadly Disc: Can throw out Heavy Mole's buzzsaws, which can be inhaled for Cutter ability.
Degraded Boss: In Mass Attack, he goes from a main boss to a mid-boss who only appears in Green Grounds - Stage 6.
Even Evil Has Loved Ones: Squeak Squad introduces us to his wife, Mrs. Moley, who, as revealed in this Dedede Directory tweet, are revealed to be a married couple.
Flunky Boss: In Mass Attack, he's aided by his Mogmole and Helmetmole underlings.

Rodents of Unusual Size: He's several times Kirby's size.
Sinister Shades: A pair of round sunglasses with red frames, and is a boss in several games.
Suspiciously Similar Substitute: He's this to Heavy Mole from Adventure, being mole-like creatures fought in a tunnel who fight by throwing projectiles at Kirby. Hammering this point home is that Moley throws Heavy Mole's buzzsaws.
Throw a Barrel at It: Can throw out oil drums that can be inhaled for Burning ability.
Throw Down the Bomblet: One of the things he throws is a Cartoon Bomb. It can be inhaled for the Bomb ability.
Whack-a-Monster: He appears from one of the several holes in the arena, throws stuff at Kirby, and then sinks into the hole again to reappear at another.

Mega Titan

A flying robotic suit of armor with four rocket-propelled fists. It lurks inside Carrot Castle and is fought in a different manner to many other bosses in the series.

Boss-Arena Idiocy: Mega Titan is fought in an extremely cramped room with walls covered in electricity. While this means you can't touch the walls without getting hurt, it's also the only way to damage the boss without bringing specific abilities.
The Cameo: Appears as a keychain in Triple Deluxe.
Floating Limbs: It has four rocket-powered fists to knock you around with.
Fragile Speedster: Titan Head moves faster, but it has the least amount of health.
Horns of Villainy: Titan Head sports a pair of golden horns.
Killer Robot: Hardwired for murder and it shows.
Multi-Armed and Dangerous: Four fists, each about Kirby's size, that can all Rocket Punch.
Nigh-Invulnerability: Its impenetrable armor shields it from non-electric attacks.
Puzzle Boss: It can only be defeated with electricity, which means you have to either 1) use Beam, UFO, or Spark against it, or 2) knock it to the electrified wall.
Ring-Out Boss: Its armored form is immune to everything except electricity, so if you don't have the Beam or Spark ability, you must push it into the electrified walls to damage it.
Rush Boss: It's fought in a small room and possesses fast attacks, so it all comes down to either defeating it very quickly or getting just as quickly clobbered.
Sequential Boss: Two phases — first as itself and second as Titan Head.
Shed Armor, Gain Speed: Titan Head moves faster once it sheds its armor, but not only it has low defense, it also loses its Nigh-Invulnerability.
Unusual Weapon Mounting: Titan Head has a missile launcher in its… head.
Who Needs Their Whole Body?: Titan Head can function alone without its armor.

Gobbler

A strange shark like creature with a propeller that wears a life preserver and fights by leaping out of the water. The boss of Olive Ocean.

The Cameo: Appears in Triple Deluxe as a keychain and in Planet Robobot as a sticker.
Dub Name Change: Apparently called "Gabriel" in Japanese. The name's written as "Gaburieru", where "gabu" means "guzzling".
Eating the Enemy: He can try to swallow Kirby, then chew him for big damage before spitting him out.
Flunky Boss: Summons tiny red sharks to attack like torpedoes. Inhaling them, strangely, gives Sword ability.
Suspiciously Similar Substitute: A battle against a water predator who summons smaller versions of himself with both an underwater and out-of-water portion? He's definitely Acro's Mirror World counterpart.
Threatening Shark: Both Gobbler and the Mini Mooks he spawns.
Underwater Boss Battle: Partially, at least, as there's a platform on the water's surface.
Wingding Eyes: His eyes turn into Xs when defeated.

Wiz

https://static.tvtropes.org/pmwiki/pub/images/wiz_katam_1.png

A magician-like enemy with a hat of nasty spells. He is fought in Peppermint Palace.

Badass Cape: Wears a wide red cloak, befitting his profession.

Floating Limbs: A pair of white gloved hands without arms.

Invisible Anatomy: His body seems to be almost entirely invisible.
Magicians Are Wizards: Has traditional magician attire, but is able to pull objects and enemies out of his hat indefinitely.
Magic Wand: A magician staple.
Poison Mushroom: The poisoned apple that he summons will grant Sleep if inhaled. Sounds familiar…
Suspiciously Similar Substitute: Wiz has many similar patterns to Paint Roller, and is ostensibly Paint Roller's Mirror World counterpart.
Throw Down the Bomblet: He can summon bombs out of his hat. They can be inhaled for the Bomb ability.
Weaponized Ball: One of the things he summons is a football.
Yellow Eyes of Sneakiness: His eyes are yellow, and they're the few parts of his body that aren't invisible at all.

Master Hand and Crazy Hand

The final bosses of the Super Smash Bros. series make their Kirby debut as the bosses of Candy Constellation. In addition, Master Hand appears as a recurring mini-boss that gives the Smash Bros. ability upon defeat.

For a list of their tropes in their series of origin, see here.

Adaptational Wimp: They're not quite as tough as in their series of origin, especially since Kirby isn't limited to his Smash moveset and can fly around freely.
Combination Attack: They can attack in tandem, catching Kirby between their fists in a dual punch or palms in a clap.
Divergent Character Evolution: Inverted, they use the mirrors of the same sprite sheet and share all of their attacks, unlike in Smash proper.
Dual Boss: Master Hand is a rare mini-boss on his own, but he then teams up with Crazy Hand to become the main boss of Candy Constellation.
Finger Gun: As one of Master Hand's signature attacks, they can do this gesture to fire bullets.
Giant Hands of Doom: They're a duo of giant floating gloves.
Ground Punch: They can make a fist and slam into the ground. Uniquely for their Kirby appearance, they briefly turn to stone when they hit the ground, and the Drop Stars formed can even be swallowed for the Stone ability.
Guest Fighter: Fitting given how Smash itself is famous for these, the Hands are guest bosses from that series.

Kirby: Squeak Squad

Buboo

A crab miniboss that covers itself with bubbles. Gives the Bubble ability if inhaled.

Bubble Gun: Can attack by shooting bubbles.
Elemental Barrier: Its bubbles act as protection.
Power Floats: Can float around while being covered in bubbles. If they're all popped out, it'll run back and forth on the ground.

Gao Gao

A mammal-like beast miniboss. Gives the Animal ability when inhaled.

Absurdly Sharp Claws: Has a pair of claws on large, long hands.
Cute Monster: Despite his big claws, he always has that adorable look on his face, even when defeated.

This Is a Drill: Has an attack where he twists like a drill with his claws as he jumps upward, then tries to fall onto Kirby.

Big Metalun

A miniboss in the form of a big, living chunk of metal. Gives the Metal ability when inhaled.

Collapsing Ceiling Boss: As it moves slowly, it'll cause quakes that makes boulders fall from the ceiling.
Cyclops: It has a single eye, unlike the Metaluns.
King Mook: Of the Metalun mooks.
Rolling Attack: Its sole attack is to retract its limbs and then roll forward. When it hits a wall, more rocks fall down from above.
Spell My Name With An S: Also called Big Metalum (likewise for the Metalum mooks).
Stone Wall: Doesn't have much in terms of attacking capabilities (and it moves slowly as well), but it's very durable.

Tedhaun

A special miniboss that can only be encountered after collecting all the Ghost Medals. Gives the unique Ghost ability when inhaled.

Bedsheet Ghost: It has this general look.
Cyclops: It only has one eye. Its Caper summons also have one eye each.
Fangs Are Evil: Has a wide grin with a pair of fangs.
Flunky Boss: Its only means of attack is to summon mini ghosts (called "Caper" in Japanese) to assault Kirby.
Orbiting Particle Shield: Tedhaun mainly commands its Capers to encircle it, protecting it from attacks.
Punny Name: Its name is "Haunted", but flipped around.

Mrs. Moley

Moley's wife, and the boss of Nature Notch.

Deadly Disc: Can throw out Heavy Mole's buzzsaws, which can be inhaled for the Cutter ability.
Death from Above: She has a move (that Moley doesn't have) where she appears in the background, then jumps up high, then a Shadow of Impending Doom appears and follows Kirby; he has to run away it as the last second to dodge the falling Mrs. Moley. If she hits the hard ground, not only will she be stunned for a few seconds, she'll actually suffer from Fall Damage, which can potentially kill her.
Distaff Counterpart: To Moley.
Psycho Pink: She fights you and sports pink flowers.
Red Is Violent: She attacks you and sports shades with red frames. She also has a bandana, claws, and a flower of the same color.
Rodents of Unusual Size: She's several times Kirby's size.
Sinister Shades: Just like her hubbie, Mrs. Moley is a boss and her shades have red frames.
Tactical Suicide Boss: Downplayed; it's not necessary to beat her, but she'll recieve minor damage if she lands on the hard ground during her dive attack.
Tertiary Sexual Characteristics: The flowers on her head.
Throw a Barrel at It: Can throw out oil drums that can be inhaled for Fire ability.
Throw Down the Bomblet: One of the things she throws is a Cartoon Bomb. It can be inhaled for the Bomb ability.
Whack-a-Monster: Downplayed in that there are only two holes in the arena (and one more in the background) compared to Moley's six.

Mecha Kracko

A cloud-creating robotic version of Kracko piloted by Doc, which fights Kirby in Cushy Cloud.

Cumulonemesis: Artificial, that is. Unlike Kracko (but like Kracko's Revenge), who's white, Mecha Kracko is dark grey.
Cyber Cyclops: What do you expect for a Robot Me version of Kracko?
Flunky Boss: Can summon Waddle Dees, Starmen, and Waddle Doos to attack Kirby.
Mythology Gag: Mecha Kracko's lightning bolts are green (as opposed to normal Kracko's white), and it's fought inside a dark, stormy tornado. Both of these traits came from the anime's version of Kracko.
No Name Given: Its name is only found in the Japanese player's guide; it's simply called "Kracko" in the game's files.
Other Me Annoys Me: According to his template's pause screen description on Very Hard difficulty in Kirby Fighters Deluxe, Kracko himself is aware of his mechanical self's existence, and is not fond of it.
Platform Battle: At the start of the second phase, it'll immediately try to sweep through and disperse the cloud platform you're standing on. Then it'll fly back and recreate a new (set of) cloud platform(s) with gaps on them. It may sometimes repeat the process after other attacks.
Sequential Boss: The only boss in the game with a second health bar.
Shock and Awe: Can shoot lightning and cover itself in electricity.

Yadgaine

https://static.tvtropes.org/pmwiki/pub/images/yadogaine.png

A titanic hermit crab-like robot piloted by Doc that serves as the boss of Jam Jungle.

Advancing Boss of Doom: It'll keep chasing from the left side.
Animal Mecha: A giant enemy who's a robot hermit crab.
Collapsing Ceiling Boss: Rocks (and Gordos) will periodically fall down from above during the battle.
Dishing Out Dirt: Its claws will kick out rocks at Kirby that he can inhale.
Energy Weapon: Can periodically shoot a red laser that Kirby has to jump over.
Shows Damage: An example that overlaps with Combat Breakdown. As you damage it, it'll lose one of its claws, then the other, and then the laser cannon before it's finally destroyed.
Spell My Name With An S: Also spelled Yadogaine.

Bohboh

A fiery flying owl monster with a raccoon tail that attacks Kirby in Vocal Volcano.

Bullfight Boss: One of his most common attacks is to dive at Kirby in an attempt to grab him with his talons. You can use this to your advantage by making him fly into the ground (which will stun him and cause rocks and enemies to fall, which can be spat at him) or the lava pool (which will do minor damage to him).
Collapsing Ceiling Boss: If he collides with the ground while swooping at you, it'll cause the screen to shake and rocks and enemies to fall. Of course, you can inhale these and spit them at him if you lack an ability (or an ability that can throw things, like Throw).
Feathered Fiend: He's a large and fat flaming owl.
Flunky Boss: If he crashes onto the ground, a Screen Shake occurs, and either Hothead, Pengi, or Sir Kibble may fall down from above.
Grapple Move: Has a move where he tries to dive towards Kirby. If he hits, he'll lift Kirby and then throw him to the lava-covered part of the arena.
Meaningful Name: A pun on Bubo, a genus of owl, and Bo, the Japanese Onomatopoeia for blowing fire.
Mix-and-Match Critters: A fat owl-like boss with a raccoon tail.
Ominous Owl: Less "ominous" and more "let me hit you already, you God-forsaken owl", but he is still an antagonistic boss.
One-Steve Limit: Averted in the Japanese version of Kirby Mass Attack, which has a fire-breathing Cartoon Creature with the same name as a normal enemy. The English localizations sidestep this by calling the latter enemy a Booboo.
Playing with Fire: Complete with Hot Wings. He can attack by dropping Fireballs as he flies.
Suspiciously Similar Substitute: The Batafire miniboss from The Amazing Mirror might be his Mirror World counterpart.
Tactical Suicide Boss: Also Downplayed; there's a lava pool in the middle of his arena, which will damage him slightly if you can make him charge into it. However, he can also use it against you if he manages to grab you.

Kirby's Epic Yarn/Kirby's Extra Epic Yarn

Wicked Willow

A cycloptic purple tree that inhabits Grass Land's Weird Woods. It is fought in Kirby's Saucer form.

Cyclops: Has only one eye.
Dub Name Change: It's called "Tosenboku" in Japanese.
Fantastic Flora: Even by the standards of the Kirby series, Wicked Willow is just weird.
Punny Name: In Japanese, its name is a pun on "tōsenbo" (obstacle) and "boku" (tree).
There Is Another: There are actually two Wicked Willows: one in the middle of the stage, and another in the end.
When Trees Attack: A hostile tree.

Blast Mariner

A huge Mariner with a cannon on his head that fires missiles. Appears in the Boom Boatyard.

Dub Name Change: Called "Hecho" in Japanese.
Hoist by His Own Petard: Kirby can use his own missiles to throw them back at him.

Space Kracko

Kracko's distant relative from space that attacks by shooting comets. Appears in the Outer Rings stage in Space Land and is faced by Kirby's Rocket form.

Cumulonemesis: Just like his terrestrial relative, he's an evil thundercloud… but from space.
Shock and Awe: Can cover himself in electricity, produce spinning electric beams, and shoot a powerful bolt of lightning.
Shows Damage: Once you shoot him, he shrinks and becomes smaller. He shrinks two times before he's finally destroyed.

Lickeur

A giant yarn monster that guards the magic yarn of Quilty Square.

Cutscene Boss: While guarding a magic yarn would usually make something a boss in this game, Kirby defeats Lickeur by turning into a weight and slamming down from above during a cutscene.
Overly-Long Tongue: There's a good reason it's called Lickeur. In the cutscene that it's defeated in, it uses its tongue to, well, lick Fluff.
Purple Is Powerful: It's mainly purple, and it's one of the guardians of a magic yarn. This is subverted, however, as it dies in a cutscene by just one of weight Kirby's ground pounds.

Fangora

A classic dragon that guards the magic yarn of Grass Land.

Back from the Dead: Yin-Yarn revives it at the beginning of his boss fight.

Dub Name Change: Called "Dodowan" in Japanese.
Our Dragons Are Different: It's closer to classic depictions of Western dragons, but it has an Overly-Long Tongue and is made of yarn.

Playing with Fire: It can shoot fireballs from its mouth.
Shows Damage: The more you damage it, the thinner its yarn outline becomes.

Shell Game: Hides himself in one of three identical top hats in one attack. The one the Waddle Dees are looking at is the one he's hiding in.
Shows Damage: The more you damage him, the thinner his yarn outline becomes.
Tactical Suicide Boss: If he just stuck with his bomb attack, he would never make any projectiles that could be thrown back at him. Possibly justified, as he decides his attacks by a slot machine, so he can't really choose what to attack with.

Capamari

A giant octopus (that resembles a squid when wearing its cap) that guards the magic yarn of Water Land.

Degraded Boss: It reappears during Yin-Yarn's boss fight, but it can be defeated upon getting hurled only once.

Shows Damage: In the second phase, the more you damage it, the thinner its yarn outline becomes.
Stealthy Cephalopod: After removing his cap to expose him as an octopus, Capamari fills the stage with ink and disappears, with his eyes later fading in as the only visible parts of him. Capamari later tries to hide in one of four jars, although he keeps sticking his head out to look around, making it obvious which jar he's in.
Tactical Suicide Boss: In its second phase, if it didn't attack with tentacles or send Octopeas out, then there would be no ammo for you to hit it.
Tentacled Terror: A giant octopus that disguises itself as a squid with its cap.
Underwater Boss Battle: You fight it underwater.
Unexplained Recovery: Despite the fact that it got destroyed after its defeat in Water Land, it reappears unharmed during the battle with Yin-Yarn when he fills the arena with water. Though it's possible that Yin-Yarn recreated it offscreen similarly to how he recreated Fangora at the beginning of his boss fight.

Lady Ivy

A giant plant queen of Sandy Canyon that serves as the second boss of the game.

Kirby's Return to Dream Land
