YMMV / Mega Man X DiVE

• Alternative Character Interpretation: When Zinogre Iris flirts with Zero, is the latter really Oblivious to Love, or faking it out of fear he'll hurt her again?
• Annoying Video Game Helper: RiCO's talkative Genki Girl nature and Cute, but Cacophonic voice can make her come across this way. Fortunately, she only talks during important story points, and once you enter your first Dive you can turn character voice volume down to mitigate the effect. Amusingly, the game itself treats her this way to an extent; when ViA joins up, one of the first things he does is says is how she's just a chatterbox and should focus on doing her job as a Navigator. They'll bicker about this back and forth occasionally during story beats, becoming more playful about it as the story progresses. iCO joining the group and being more of a Deadpan Snarker also helps a lot.
• Best Boss Ever:
  • Naturally, Magma Dragoon became this as soon as he made his appearance, bringing everything from his game of origin including all of his homages to Street Fighter and the ability to fight him in a Ride Armor.
  • The Servbots during the Legends event became this when they showed off that they were a different kind of boss, by attacking the player as a set of five.
  • ViA during the ViA's Training event for the first anniversary. This is as close as we can get to an X vs. Zero fight in the game, complete with the appropriate theme from X5 playing during the fight. The stronger he gets throughout the game's story, he also begins growing beyond Awakened Zero's potential, absorbing skills from Absolute Zero and Omega to create a fighter that embodies every incarnation of Zero in the franchise. Which tracks, given he is the origin of the "Robot Destroy Mode" coding Wily would go on to put in Zero; ViA is effectively about as close as you can get to a literal Super Prototype of Zero. An actual remix of the X vs. Zero theme plays for his role as ViA -Square- in the Final Boss just as well.
• Broken Base: The PvP component of the game. Either depending on who you ask, it's either it a crucial part of the game (and thus its exclusion in Offline to be lamentable) or unbalanced, unfun garbage that has no business being in the game, is basically "pay to win" (all the top-tier characters and weapons are S-rank, some even being limited) and its exclusion in Offline means nothing of value was lost.
• Common Knowledge: There are rumors of Offline's backend being fundamentally different from the online version, something parroted by NebulaJoy themselves. Actual analysis by modders reveals this to be mostly false aside from missing content and no connectivity.
• Complacent Gaming Syndrome:
  • The final weapon of each type - Ultimate Buster, Miracle Saber, Fantasia Comet, The Deconstructor and Light Bender - all quickly become go-to weapons due to being strong and having piercing attributes that lets you fire through walls. PvP matches involving them can quickly turn into both sides shooting each other from halfway across the battlefield without even getting close to the opponent.
  • In terms of chips, Sting Chameleon's sees the most use by far. A solid two seconds of invincibility once you get hit that can be applied to any weapon is nothing to sneeze at. It's pretty much a requirement in PvP to equip it on both your weapons if you want to avoid the worst attacks.
• Disc-One Nuke: After beating the 1st boss Maoh the Giant in Offline, you get your first gold-tier character in Mega Man X S-Class Hunter. Since the results of winning a scenario depends on how fast you finish and how much remaining health you have, S-Class Hunter X can breeze through these as he starts off with a extra effective damage reduction and later can generate indestructible force-fields if he gets hit (usable after a cooldown period). He can learn to get a speed boost if he shoots a homing missile and evolve into getting a health recovery after killing enemies. Since fighting most enemies is optional, S-Class Hunter X can simply run through obstacles and enemies letting his impressive defenses handle the damage.
• Epileptic Trees:
  • The altered ending in Offline includes a stinger where after the player gets up and leaves their system, the music changes and the screen glitches out into a very specific string of text repeating itself constantly. The meaning of this is a hot topic of debate, with the most common speculations taking the form of the sequence being some kind of Sequel Hook.
  • Though the artbook has referred to these concept arts◊ as "unused Iris -another- designs", the fact that she has blonde hair as opposed to Iris' brown along with the general design philosophy mirroring Signas more than Colonel has lead to people believe that it's actually an unused What If? variant of Alia, where she takes over as leader of the Maverick Hunters. It doesn't help that previous "unused designs" were Capcom hiding development material, in the Mega Man Legacy Collection, for a future title!
• Evil Is Cool:
  • Sigma demonstrates this with his selection animation having him destroy a few Mechaniloids and seemingly kill X, only to show that "X" was an Armored Soldier with a holographic skin on it, along with his Badass Cape appearing when he starts and ends a stage. A second playable version of him, labelled as his X4 Second Form, has this treatment primarily because of his design evoking The Grim Reaper.
  • Vile shows this off in gameplay with his shoulder-mounted cannon. His Halloween variant pushes this by being a vampire. Vile Mk-2 got to show this off when he was added thanks to his ability to summon the Goliath Ride Armor as a special ability, finally allowing players to take control of Vile's signature Ride Armor.
  • Bit is in this category thanks to his memetic status from the Manga for X3, as well as being a member of the Quirky Miniboss Squad.
  • Ferham uses her Crimson Shadow skill, acting as an AoE attack which makes her a Walking Wasteland.
  • Awakened Zero is of course Zero's Superpowered Evil Side, making him as close as players can get to Dr. Wily's magnum opus.
    • Omega in a manner similar to Awakened Zero by being Zero's original body now programmed to act in a manner that Dr. Weil has in mind. The fight against him makes him the Akuma of the series by being a sort of Glass Cannon.
    • Once more with Zero Nightmare, a virus replicating Awakened Zero with noticeable glitches in his coding.
  • Copy X is as close to Keiji Inafune's original idea for the first Zero title, by playing as how X would using the Ultimate Armor in X5.
  • Pandora is in this category as well due to her Woobie, Destroyer of Worlds status thanks to ZX Advent.
  • Bass.EXE seeing as he is the rival to MegaMan.EXE and has traits that are akin to a virus. He later got his own upgraded version courtesy of his fusion with Gospel to become "Bass GS".
  • Classic Bass is this in spades, due to him being created by Wily to be Mega Man's rival and being programmed to defeat Mega Man at all costs. As Super Bass he's even more powerful and at five stars and a fully-unlocked DNA code he is one of the characters who stands out as an outright Game-Breaker, marking him as indeed one of the strongest robots.
  • Magma Dragoon, per above, but now for the reasons of playing as a Shotoclone and one of the many Something Animals present as Maverick bosses in the series, with him being the very first animal-themed Reploid in the entire series to be actually be playable.
  • He's not really evil, but ViA -square-'s design evokes this trope, with white Bishōnen hair and a cool set of armour and wings that resembles a hybrid of Super Bass and Zero, one imagines someone took inspiration from Sephiroth for his design.
• Fan-Preferred Cut Content: Droitclair's prototype design instantly became more beloved by the community once it was revealed in the artbook, due to the interesting use of her "hair" being used as energy tonfas as well as how much sleeker and more-inline with the X series her overall appearance was. This is in stark contrast with her final design, which is overly-designed with many calling her a discount Vocaloid V-Tuber.
• Fandom-Enraging Misconception: The game's modding scene is not "just a bunch of reskins," and any attempt to bring this up outside of the global server (the main origin point of this remark) will be met with a swift correction. While many custom items are indeed pulled from pre-existing assets, a few do have unique models, and all of them are functionally different from the game's vanilla library of weapons (well, at least as different as the game's code permits.)
• Fan Nickname: Upon the reveal of Iris -another-, players began to give her nicknames to differentiate her from the original one. Such include "Colonel Iris" referring to her as Iris using Colonel's A.I., "Major" based on older fan art of her dressed as Colonel, or "Iris Alter" in a manner similar to how Artoria and Herakles had been altered into dark malevolent versions of themselves.
• Fridge Horror: In the "Burning Brides of June" event, Pallette is pissed that she didn't get a wedding makeover like Alia and Layer, and threatens to "provide erroneous route navigation" in her tirade. While this sounds like a Poke the Poodle moment, when you remember that her job is to guide Hunters through dangerous environments looking for Mavericks, doing her job wrong could be fatal.
• Funny Moments:
  • Much like in their game of origin, the Servbots are just as silly be they being used for a Zerg Rush attack or as part of a Wolf Pack Boss.
  • During the Bon event, the Mad Joey riding the REX-2000 has an Unexplained Accent making him sound like a Jive Turkey. This is lampshaded since even he doesn't know why he has it.
  • As the story progresses, RiCO's personality slowly becomes Denser and Wackier, becoming almost a sort of Pungeon Master.
  • During the rerun of the Classic series collab, RiCO mentions the appearance of the series standard Scrappy Mechanic Disappearing Blocks. While RiCO at first expresses a calm demeanor regarding comitting the pattern to muscle memory, when questioned by ViA she admits that she hasn't been able to get past the damned blocks herself!
  • During the second Monster Hunter Rise crossover even with Crimson Valstrax Zero and Zinogre Iris:
    • It turns out iCO is also a Monster Hunter junkie, but isn't as good at playing it as RiCO, much to her frustration, and tries to pester her sister and the Player into helping her in co-op.
    • Zero and Iris are from in the middle of X4. Iris is pining for Zero, who is, uh, still very much Oblivious to Love.
    • Chameleos Chameleon (aka Sting Chameleon merged with the data of Chameleos) tries to take Iris hostage. Unfortunately for him, Iris is currently merged with Zinogre. Three guesses what happens next, and the first two don't count.
  • The second Valentine's Day event revolve around RiCO and iCO's idol forms. The latter wants absolutely nothing to do with it, until she's forced to as it is the win condition for the stage in order to correct the irregular data involved. Also, Byte is here, and he's pink for some reason.
  • During the character select screen for Mega Man Volnutt's alt. costume, it shows him contemplating a soda vending machine, just like in the games he kicks the crap out of it, breaking it into pieces.
• Game-Breaker:
  • Multiple S-Rank characters are fairly broken at five-star rank, but Super Bass in particular is considered one of the top-tier characters if not the top-tier at present. Both of his active skills are fairly good on their own, but both their third unlockable chips are extremely potent in a combo, with Sweeping Laser weakening defense and then Bass Buster unleashing a triple shot. The Evil Energy passive, however, allows you to use both skills twice in a row, with the higher cooldown for the double use (each skill has its own longer cooldown for the second use separate from the regular skill cooldown) being a relatively minor downside for what is basically an obscenely powerful setup where you can put on four stacks of defense reduction and then deal obscene burst damage at close range. His Animosity skill allows him to gain invincibility just by hitting an invincible target (the invincibility also has a small chance to be triggered upon taking a hit), and he gains extra damage when having a buster equipped, on top of a 10% damage reduction. His fixed DNA codes are also incredibly powerful, giving him an additional 20% damage reduction when equipping a buster, a health regen every 6 seconds for 20% of his attack upon defeating an enemy, and an additional 30% damage boost to Sweeping Laser along with the skill applying the defense reduction no matter what. With the right cards (especially Proto Man's Trap) you can boost his damage and damage reduction from equipping a buster to a whopping 40% or more. This time, he can legitimately stake a claim for the title of the strongest robot.
  • The dash slash canceling trick from the PlayStation trilogy is reborn, where you can restart the combo of melee weapons by simply tapping the dash over and over and over, making them far more lethal than they were ever balanced to be. Even better, you can still make distance while doing it. And it's outright been acknowledged by the developers themselves. Combine this with some of the nastier S-Rank swords and the right chips in PvP, and you've become an "Instant Death" Radius. At least, if someone doesn't nuke you with a skill or beam you through a wall, first.
  • Next DiVE Armor X is absolutely busted, even before you max him out, and once you do max him out he's basically the most broken character in the game. Even before you consider his passives, his first skill, his charged shot, is a Wave-Motion Gun that can be fired four times in a single charge and the cooldown is only two seconds without the cooldown reduction chip, meaning it is very easy to spam. The second skill can be customized to either be a Giga Crush, the Nova Strike or double beam swords, the latter two of which are so huge that you'll hit your target anyway and lack the wind-up of the Giga Crush (though the Crush has a chip that allows you to retain 20% of armor energy, making it easier to fill it again), and the first passive leaves behind a damage field when it hits the first target (on top of also giving a 20% damage reduction bonus). The other passives are just as absurd - "Ace Hunter" provides an anti-debuff shield when using skills and accelerated status with no cooldown, "Skilled Hunter" generates a damage-absorbing shield when skills are used and gives you a 30% damage increase and damage reduction bonus when equipping a buster and melee weapon in your loadout, "Weak Spot Lock" applies stun to targets that get hit by the Giga Attack and up to two stacks of defense reduction debuff of 24% to targets that are hit by the charged shot (which again, can be easily spammed) and provides another passive 20% damage boost when the speed boost from "Ace Hunter" is active (which, again, has no cooldown), and "A True Hero" makes the charged shot nuke all of a target's buffs, restores armor energy when hitting a target and reduces damage by 20% when "Skilled Hunter"'s shield is active. The only thing he doesn't have is any kind of health regen, but that's easily fixed with the right cards, allowing him to not only output monstrous amounts of damage, but also be very survivable and able to nuke an enemy's buffs while putting debuffs of his own on the target. He is very much worth rolling for, without question. It should say it all that in Offline, he is one of two playable characters in the game locked behind defeating the Final Boss (the other is the Final Boss himself).
  • All the "ultimate weapons" are quite obviously the best in the game for each weapon class - Ultimate Blast (large homing shots plus a laser), Miracle Blade (powerful melee weapon with two different easy methods to fire off energy projectiles and the ability to steal buffs), the Deconstructor (basically a minigun and a shotgun combined when fully upgraded, capable of wide shot range and stupidly powerful single-target damage), Fantasia Comet (powerful launcher also with homing shots which can split into three more), and lastly the Light Bender (it's a friggin' beam chainsaw and has the highest DPS of any "sprayer" weapon, enough said). There are other powerful weapons in their classes, but all of these are at the top.
  • The Offline release gives S-Hunter X and S-Hunter Zero very early, all required parts to unlock, no strings attached, and makes it possible to max out S-Hunter X's rank early as well with nothing but Zenny, and they are invincible while using their Skills.
• Good Bad Bugs: Due to an item duplication glitch, some events that require collecting items can be made trivially easy. For example, the Core Chip Recycling Campaign requires collecting 12 hidden elements, of which there are only 18 available; due to this glitch, it's possible to finish with several hundred.
• Heartwarming Moments:
  • Iris being made playable and with a new voice was met with much delight as now she and Zero are together once more. The same can be said of Zero (Z) and Ciel after the end of Zero 4.
  • Speaking of Ciel, the Valentines Day version kicks it up a notch by having one of her skills summon Cyber-elves to help her attack. On occasion, Passy, the Sacrificial Lion from before the events of the first game take place, will make an appearance in full form. Not even her Heroic Sacrifice can stop her from helping defeat Mavericks.
  • Likewise, Mega Man Legends 2 ended with Mega Man Volnutt stuck on the Moon, meanwhile Roll Caskett and Tron Bonne put aside their differences to build a rocket ship and save him. The cancellation of Legends 3 means they don't get the chance to succeed. X DiVE made all three of them playable.
  • The Stinger for the Offline version shows a Big Damn Reunion between RiCO, ViA, and iCO, and the player, satisfied, gets up and leaves their room. This is followed by RiCO thanking you for playing.
• I Knew It!:
  • Many assumed that Iris' new voice actress would be Aya Endo due to her having succeeded two roles (Minnie Mouse and Caris Nautilus) from Iris' late original VA Yuko Mizutani. They were proven right when Iris' voicelines were patched into the game on July 9, 2020.
  • Despite the efforts to hide the identity of Festival Zero on social media, the players already figured it out since the yukata had a pattern with Zero's helmet on it.
  • The use of Cyberspace in the game had players wondering if the Battle Network series was to be included. Sure enough, it was confirmed on November 20, 2020, as both MegaMan.EXE and ProtoMan.EXE were announced as playable characters. It was also theorized that Cyber Peacock would make an appearance as a boss, before being confirmed on November 23, 2020. Many fans also assumed that Bass.EXE would also become a playable character as well before it was confirmed five days later.
  • After fighting Magma Dragoon the first time, he mentions to the player and RiCO about returning as a Hunter Program. Surely enough, he was confirmed as a playable character on January 18th, 2021.
  • Even though Iris was added in early July 2020, many expected her brother Colonel would appear in the game in some capacity. Sure enough, he was confirmed as the boss of the Valentine's Day 2021 Event. Due to his voiced lines during the fight, it wasn't long before speculation began that he would be playable, which turned to be correct in mid-April 2021, starting on April 21st as part of the "Supreme Commander of Repliforce" event.
  • A similar occurrence came about on March 1st, 2021 when Harpuia was announced as a future playable character. Given the fact that Leviathan was already playable, it was generally assumed that the other members of the Four Guardians would follow suit.
  • RiCO was announced as a playable character on March 16th, 2021, after fans theorized for a full year that she would eventually be playable.
  • After both Volnutt and Tron were added, it was assumed that Roll Caskett would be added. Sure enough, she was announced on April 4th, 2021.
  • Bass, as in the Robot Master from Mega Man 7, was speculated to be appearing as soon as Bass.EXE was announced during the Battle Network event. Sure enough, he was confirmed on May 3rd, 2021 for the rerun of the Classic series event.
• It's the Same, Now It Sucks!:
  • Seems to be a common complaint on social media, as most complaints are directed at the music choices for event stages or boss fights, relying on the boss themes from X1 and Wood Man's theme from Mega Man 2. Fortunately, later updates have fixed this issue for the most part.
  • SD Second Armor X and Zero have gotten a lot of heat with their announcements as they are functionally the same as their regular counterparts but with better stats instead of having new skills.
  • Same goes for S-Class Hunter X, who is literally just a better version of X with more powerful skills and with what is basically a constant Super Saiyan aura. That being said, he's also literally the first welfare S-Rank Hunter Program, available for free just for logging in during the Christmas 2022 event, so it's much more excusable.
  • The Global Server Exclusive Maximum Massimo and True Zero (Z) gets this worse, as just like with S-Class X and Zero, they're just the same characters but with buffed skills and an added Battle Aura. Unlike S-Class X and Zero, the people in charge of the NA/EU Online version tried to pass them off as premium gacha units, making their Multi-Slot Character issues all the more apparent. The later release of Vengeful Vile only served to exacerbate this negativity, as it had the added criticism of simply feeding the meta for raid/guild bosses through cooldown reduction and stat buffs instead of doing anything innovative with an S-rank Vile (especially when his Mk. II and Halloween variants already exist.)
• Memetic Mutation:
  • "I don't code the thing, my friend."^explanationPart of a quote from the global version's community manager and a supposed developer, Zero-X, who had been attempting to explain (in response to a bugged release) that MAXIMUM MASSIMO had worked fine in production. Often used as a jab at NebulaJoy in conjunction with other quotes suggesting a lack of knowledge about how the game actually works (notably saying Offline could have taken over a year to rework, when analysis of the game's code reveals minimal changes besides network disconnections), with the full quote sometimes abridged to "I don't know, I don't code."
  • Dependencies/"The Big D"^explanationThis type of Unity programming error is bar none the most common issue that comes up when trying to create new content for the game in mods, to the point of ridicule.
• Moe:
  • RiCO immediately hit this status thanks to her voice and perky nature.
  • In regards to playable characters, Roll, Iris, Cinnamon, and Palette brought this over from their source games. Roll and Iris even carried this over when they got Swimsuit versions. Aile joined these ranks when she was added and carried it over with her Halloween version.
• Nightmare Fuel:
  • During the cutscene following ViA taking out the Goliath's defenses (much like Zero's classic Heroic Sacrifice), he is shown with half-of his face eroded away, ala Two-Face, revealing a skull-like face with a helmet design similar to Ra Thor. Attatched to the art assets for ViA is the name "Naught", as if to imply something sinister regarding his past in the Deeplog.
  • Sigma per the norm regarding his intro (which involves him simulating X's murder) and his Raid Boss forms from X4. Considering that he is categorized as a Hunter Program, using his appearance from after he went Maverick, something seems to suggest that Mavericks are viable to make use of correcting Irregular Data, despite the fact that Sigma himself launched the initial Maverick rebellion.
  • Omega and Copy-X are in a similar situation themselves. On one hand, we have Copy-X who is a Knight Templar on what he considers to be Maverick, be they innocent civilians or his own Neo-Arcadian Military, now roaming about the Deeplog "correcting" what he considers to be Irregular Data, even if it's the player doing the job of correcting it. On the other hand, we have Omega, The Antichrist of Reploids through and through, now leaving a path of destruction in his wake to the Deeplog, Irregular Data and player alike.
  • The stage for the Halloween Episode, Brambled Castle, plays up all the tropes of it being a haunted castle, including the low lights, making it hard to tell if you're about to fall into a pit, a bed of spikes, or run into any of the stage's Demonic Spiders, the ghosts.
  • Lampshaded during the fight with the Yellow Devil. ViA and RiCO talk about how many players' failures developed PTSD from fighting it in its game of origin.
• Older Than They Think: Bass's revealed gameplay for his playable appearance has him using a moveset based on MM7's Battle Mode, which includes his ability to charge his buster rather than shoot it like a minigun. That being said, the multi-directional firing he originated in Mega Man & Bass is no longer unique since everyone can do it in this game.
• Only the Creator Does It Right: Post the shutdown of the official Capcom-published version, an increasing number of players are finding that Nebulajoy's version is akin to a shambling corpse, with endlessly repeating events and no truly new content, with Nebulajoy themselves simply refusing to accept the game died over a year ago, with Capcom themselves giving the full game experience for a single one-off payment that's far less than Nebulajoy is expecting people to pay for their supposed new content.
• Scrappy Mechanic:
  • Sometimes shooting what you want to shoot doesn't quite work as intended. The game uses an auto-lock system that will fire upon the nearest enemy, which can be incredibly over-zealous and even start firing at enemies off-screen behind walls. You'll find plenty of cases, however, where it simply fails to pick up foes properly, even those shooting at you from beyond the screen edge, or that you have to stop firing to refocus on a closer target or even having no way to shoot a boss or more dangerous enemy because of a closer target. And then there's the fact that your character will face the direction they were last shooting in for a second after you stop firing if there is nothing new to lock-on to, meaning trying to pop enemies out of view becomes immensely more delayed and clunky than it needs to be. Notably, you can mitigate this by turning off the auto-aim feature, allowing for either a twin stick shooter sort of feel like more recent Contra titles, or play it entirely classic by only being able to shoot left and right as a Self-Imposed Challenge.
  • Player vs. Player lets you use any Characters, Weapons and both their Skills attached, as well as your Chips, only excluding your Dive Trigger Skills. It also doesn't really care how upgraded your gear is or what level you are. The result is that it's rare to get a match where one player doesn't completely and utterly destroy the other. You might think you're ready to rumble with your shiny new S-Rank character, only for someone to one-shot-kill you from off-screen, while subsequently being shielded from everything you throw at them for several seconds at a time.
• Spiritual Successor:
  • Can be considered one for both the canceled Rockman Online, involving recreations of the main cast of both the X and Classic series, some version of Bass wearing a cloak, and the introduction of three characters original to the game, and for Rockman Xover, by nature of being a smartphone title making use of a light blue girl (Kalinka or RiCO) and a Crisis Crossover involving all seven series in the franchise.
  • Gameplay-wise, to Contra Returns. Both takes on a long-running 2D platformer franchise, making it ran as a freemium game with RPG-elements, with bite-sized stages on the story, resource gathering, and PVP duel modes. It also controls the same too, with auto aiming and buttons for skills.
• Surprisingly Improved Sequel: In a meta-example, the entire game is this to Rockman Xover. While Xover was panned for its gameplay merely being "jump and shoot" dulled down with mediocre graphics, DiVE does manage to make the gameplay replicate the style of the Mega Man X games alongside decent 3D graphics, though much like any other gacha game, in the West, their monetization scheme is polarizing.
  • This made Offline all the more welcome, as many find the gameplay adequate but disliked the gacha elements, though this came at the cost of losing the crossover content and multiplayer (though while people lamented the loss of co-op, the loss of PvP was much more divisive).
• Tainted by the Preview: While the offline version has a number of praises for preserving the game's data and removing the Allegedly Free Game elements, the removal of all material related to PvP and crossovers generated considerable rejection from fans as they consider it to be the vital part of the game. When Offline's release date was announced, pre-orders for Steam went live shortly after, which revealed to players that the game cost $30 USD at launch with some feeling that such a price tag is way too steep given its simplified gameplay and that the cost is somehow on par with the Mega Man Legacy Collections, which contains 4 to 6 full games at a time.
• Tear Jerker: The entirety of Chapter 20. Everyone knows what's coming, and despite RiCO's best efforts, ViA and iCO willingly allow themselves to be destroyed to eliminate the "Robot Destroy Program" and restore the Deep Log.
• That One Attack:
  • Omega's Ryuenjin hits harder than it does in Mega Man Zero 3 due to the way the game's hit registration and flinching work; if he strikes you on the initial uppercut, he'll land an inescapable second hit through contact damage when he comes back down. While this isn't a problem in the event version of his fight where power levels are enabled, Raid and Guild Bosses use significantly lower fixed HP levels based on the star count of the current loadout, meaning Ryuenjin is guaranteed to take out a significant chunk of your health if it connects and you don't have access to a barrier skill.
  • ViA inherits Omega's Ranbu in later versions of his fight, which flinches on contact. While all of his other attacks are more akin to normal Mega Man damage scaling at high power level deficits, Ranbu's slashes can easily hack away over half your health if you aren't at level.
• That One Boss:
  • In the normal stages, Rangda-Bangda W proves to be just as difficult as normal, even with the tweak to have the spikes only appear during the wall phase. It was then followed up by Mad Nautilus being a Damage-Sponge Boss with a small window to Attack Its Weak Point and shooting lasers from his tentacles. During the Boss Raids, Final Form Sigma proved to be such a case as he flicks through the three phases (Earth Sigma, Gunner Sigma, and the minibodies) with hardly enough time to react to his attacks.
  • The Yellow Devil returns as a boss in Chapter 14-6, and is just as hard as you remember him. This is even Lampshaded in game with RiCO and ViA referring to other players of the series having some form of PTSD from having to fight it and throwing their controllers in rage. Fortunately, crouching makes the moving blob phases easier, much like the Shadow Devil in X5, but you still need to stay on your toes at all times.
  • Magna Quartz can't even be damaged unless you you hit it a certain number of times, and then it goes back to being invincible shortly after, making it a significantly bigger pain in the rear than it was in X2.
  • Magna Centipede's attacks aren't easy to avoid, and he will pull you towards him, and if he grabs you, he will recover a large chunk of his health, meaning lower-power players can't so easily brute-force him with revives unless the player stays as far away from him as possible and attacks from afar.
• That One Level: The XP Event stages, where the player has to climb down an incredibly slow moving stage while avoiding and destroying enemies while also collecting items for points. With no way to speed up things and the high risk of having to do it all over again should the player slip up and fall past the kill zone before the platforms below can spawn, most players just opt to take the reduced rewards for using Skip Dive than playing these stages daily.
  • Doing Stage 2-2 on Challenge Mode, this stage is oddly difficult to survive. The bulldozer that chases you will One-Hit Kill you if you don't escape it. It can even shatter an otherwise Nigh-Invulnerable force field (though this time you lose 50% of your max health rather than automatically die). Unfortunately to escape the bulldozer, you need to kill every enemy you encounter, which isn't easy as enemies have their health greatly increased. This makes Level 2-2 challenge significantly harder to survive than many of the other challenge mode levels after it. Other levels that include some type of advancing doom are similarly difficult to deal with.
• They Wasted a Perfectly Good Character: With the game's live service entering shutdown in September 2023, people have brought up this criticism not for the characters that are playable, but for the characters that weren't, with many noting glaring omissions such as Prometheus being missing despite he and Pandora being a Brother–Sister Team, Berkana and Gareth from Xtreme 2 are nowhere to be found, Sigma's human-sized forms from X5, X7 and X8 are absent despite having fully extensive movesets in those games, and while the Jakob Orbital Elevator was adapted as a challenge tower, Lumine doesn't even get so much as a passing mention. This extends to armors as well, as while Next DiVE Armor X was well received, a subset of the playerbase also couldn't help but wonder where were the Blade, Glide, and Neutral Armors, and many assumed Capcom Taiwan was messing with them when they announced White Day Axl over White Armor Axl.
  • In the case of Prometheus, it is noted in an interview that he was being considered for the online version, but the game's end-of-service was determined during that time frame.
  • With Iris -Another- and X -Kai- being adapted as playable characters, it opened the flood gates for other potential What If? characters or deep cut Canon Foreigners, such as the possibility of Clear Armor X from the Mega Mission Data Cardass and manga series, or Alia getting her own variation of the Fourth or Falcon Armor (lining up with how she was able to reverse engineer and repair Dr. Light's technology in X5 and X6). Unfortunately, none of these didn't seem to be considered at all, as most of the game original forms are either DiVE Armors or seasonal and crossover outfits.
• Underused Game Mechanic: Skins were introduced early on with the likes of X and Marino as a way to introduce new player outfits without resulting to bloating the roster with near-identical characters with only slight variations (such as Zero (Z)'s different forms introduced in Zero 2 onwards). However, it did feel like the developers gave up on this shortly after Ultimate Armor X got his Legacy Collection skin, with Rising Fire X and Thunder Beam Mega Man being treated as separate characters entirely despite their much-later releases, and it took until the modding community got their hands on Offline did that feature started to see use with other characters.
• Unexpected Character:
  • Ciel from Mega Man Zero becoming a playable character is one, as she is a Token Human among the playable Reploids.
  • With the announcement of the Mega Man ZX collab, Aile became one, primarily as she appears in her default human form rather than Megamerging with Models Z or X, instead using Megamerge as a temporary transformation.
  • Coupled with And the Fandom Rejoiced for the Mega Man Legends collab. Both MegaMan Trigger and Tron Bonne were thought to have been pushed to the wayside, given how Legends 2 was Left Hanging and Legends 3 was cancelled. Even moreso since Tron is shown fighting outside of her Gustaff, but she is able to use it for a special ability.
  • On the boss side of things, Dark Man 3 during the Mega Man (Classic) collab seeing as he is often overlooked since he between The Dragon of his source material and the Dark Man seen in the animated series. But he proved to be more than a capable boss, borrowing from Dark Man 4 and his original fight. This happened again when the collab reran on May 5, 2021, as Dark Man didn't appear, but Bass did bringing Treble with him.
  • Similarly, Copy X was one that became Promoted to Playable after appearing as an Event Boss.
  • Bass.EXE took players by surprise as he was announced in the stead of the expected Roll.EXE and before his original counterpart from Mega Man 7, who would later be added on May 5th, 2021.
  • The inclusion of Bit as playable was quite a surprise, due to how minor of a character he is. Though he's also always been an Ensemble Dark Horse in Japan due to his portrayal in the Rockman X3 manga. In light of his appearance in the game, Asian players on Twitter began posting his memetic scene from the manga en masse.
  • As soon as players hit Level 125 and took on Co-Op stage 11-2, they were met with the sight of Drill Man as the boss instead of a Maverick like in previous stages. Adding to this, Drill Man can be fought outside of Co-Op Mode in the game's Challenge Mode, so long as the player is at Level 125.
  • White Day Axl became one as most people were expecting the standard White Axl from X8 or X in the Fourth Armor. For that matter, it was interesting to find out that this version of the rookie Maverick Hunter was classified as an S Rank Hunter in the game
  • While the appearance of the General was already known for the "Supreme Commander of Repliforce" event, the appearance of Iris -another- was a huge surprise given the fact that Iris and Colonel have incompatible programs, thus necessitating the split from the core program. In fact, she is almost a window to an in-universe What Could Have Been, showing what Repliforce had in mind for their attempt at copying X's free-thinking AI, had they been able to overcome this problem.
  • From out of nowhere, the Canon Foreigner X-kai-, an Evil Knockoff of X that originally debuted as a collectable action figure.
  • The very announcement of Ryu and Chun-Li became one, as the two aren't even from the Mega Man series, but given the fact that X has been able to perform some of Ryu's moves in the games, it seems fitting.
  • The announcement that Dr. Light of all characters would be playable threw most fans off guard, given that he is usually depicted as a non-playable support character in the vast majority of his appearances.
  • While the Monster Hunter collaboration forms were seen as cool and practical (since Rise was still going through major releases during those times), no one was expecting sudden Devil Trigger forms for X and Zero, since it's been nearly two years since Devil May Cry 5 Special Edition launched with no other Devil May Cry project seemingly in sight outside of Peak of Combat and the upcoming Netflix series.
  • With the original Taiwanese servers shutting down, many assume that the NA and EU servers would go through the motions and run through all of the original Online version's content before closing shop as well. Then they announced that Massimo and Zero (Z) would get their own powered-up versions similar to S-Class X and Zero before them.
• The Woobie: Palette. During the "Swimsuit" and the "Wedding Dress" events, fans were quick to notice that while Alia and Layer kept getting new costumes, Palette kept getting left out. Capcom Taiwan seems to have taken notice of that, and had her as an end boss at the end of the Wedding Level, throwing a small tantrum about it. In the end, however, it seems that they've decided to toss Palette fans a bone not only by having a design contest for her own bridal outfit, but also giving her a swimsuit in July alongside Ferham and Tron Bonne (and it was with a free daily 10-time capsule, meaning players had a much higher chance of getting her when she was available). As Ferham herself put it:
  Ferham: Look. The girl who couldn't wear the wedding dress is so happy now since she's able to wear a swimsuit.
