Playable Characters

    Vent & Aile
Above: Vent and Aile in ZX, Below: Aile and Vent in ZX Advent
Vent voiced by: Sanae Kobayashi (ZX), Kenji Nojima (ZXA, JP), Dario (ZXA, EN)
Aile voiced by: Sanae Kobayashi (JP), Yuko Yunokawa (ZXA, EN)
The main protagonists of ZX, although that "s" there is used loosely since only the one you choose to play as appears in the story. Ten years ago, their mother was killed in a Maverick attack. Working for Giro Express, they are asked by the Guardians to transport the Biometal Model X, setting the events of the first game into motion. Theynote  return in ZX Advent and work with Grey and Ashe to put an end to Model W once and for all.

  • Action Girl: Aile, of course.
  • Ambiguous Situation: It's never explained whether the two are siblings, or Distaff/Spear Counterparts of each other.
  • Arm Cannon: As Mega Man Model X.
  • Badass Adorable: Both characters in ZX, although Vent grows out of it by ZXA.
  • Bag of Spilling: In the interim between ZX and Advent, Models H, F, L, and P are stolen from their lab and again land in the hands of the bad guys.
  • Big Brother Mentor/Cool Big Sis: To a degree, they act like this towards Grey and Ashe, though Aile is much more successful in that regard with Grey than Vent is with Ashe.
  • Big Damn Heroes: Multiple times in Advent.
    • Mimicking Giro's below, he/she uses the exact same move against the spider boss in the second game's Quarry mission.
    • For the final mission, they show up alongside the Guardian Base to mount an aerial assault on the Ouroboros with Grey/Ashe and the Hunters after the Hunter airships were destroyed.
    • They pop in to Hold the Line against the four enemy Mega Men and provide Grey/Ashe the opportunity to confront Albert without any interruptions.
  • Bishōnen: Vent in the second game.
  • Boobs of Steel: From the first game to Advent, Aile didn't just grow vertically.
  • Butt-Monkey: Vent, though this is more to the fandom than in-story. One official art depicts him doing cleaning for Ashe's room, with his face seemingly unsatisfied.
  • Cool Bike: That lasts for all of one cutscene. There are traces of biker badassery in a promo trailer, though.
  • Crossdressing Voices: In ZX, Sanae Kobayashi voices both Vent and Aile.
  • Defeat Means Friendship: How the Bash Brothers of Grey/Aile and Ashe/Vent comes to pass in ZX Advent.
  • Dug Too Deep: Their stage in ZXA.
  • Expository Hairstyle Change: In ZXA, Vent grows his hair out to the point that he's now an Expy of Giro while Aile has a waist-length ponytail.
  • Expies: Of the original Mega Man himself and due to their dynamic with Giro, of X as well.
    • In Advent, the older Vent and Aile resemble Evoluder Guy and Mikoto.
    • Many fans have noted that the younger Vent reminds them of Trigger.
    • In ZXA, they move on to being the Proto Man equivalent to Grey/Ashe's Mega Man.
  • Fighting Your Friend: Against Giro. Serpent, you bastard.
  • Fingerless Gloves
  • Guys Smash, Girls Shoot: Vent is often portrayed in official arts as using the saber form of Model ZX's weapon, while Aile uses the buster form. Of course, that doesn't give any difference in gameplay.
  • Half-Identical Twins: Either this or Distaff/Spear Counterparts.
  • Hartman Hips: Aile, especially in the cutscenes.
  • Hero Antagonist: In the second game due to a misunderstanding. After Grey/Ashe fight them, they stop being antagonistic.
  • Heroic BSoD: Vent and Aile suffer this twice: the first time is when they arrive at the Area H theme park, where they lacked responses to their support group as well as snapping as to where the Biometal is before explaining why they were acting strangely (the fair was the place that the mavericks attacked and resulted in their becoming orphans); the second is when they learn from Serpent that their hatred of Serpent resulted in Model W reawakening, allowing Serpent to be absorbed into Model W. They get better both times, though.
    • And one more for Aile: Before Serpent dies, he tells Aile that "the blood of the creator of Model W flows through her veins", who is eventually revealed to be Master Albert. She's shocked and then she questions her own destiny. Giro then gives her a pep talk.
    • Get a Hold of Yourself, Man!: Prairie for the first time, and the 6 Biometals for the second time. And Giro's spirit for the last one with Aile.
  • Heroic Bystander: Combined with discovering Model X and taking a level in badass at the beginning of ZX in order to save Prairie and the The Guardians from Giga Aspis. Vent himself comments that if he just stood by and watched, he'd end up regretting it later down the road.
  • Hot-Blooded: Vent in ZX. He mellows out considerably in ZXA, but shows a few traces of his previous hot-headed nature.
  • It's All My Fault: They have a breakdown when Giro dies, lambasting themselves for rushing into the fight without any plan aside from kill any Mavericks they saw. They even go so far as to wonder why did Giro have to die when it should have been them, but Prairie quickly snaps them out of that mindset.
  • It's Personal: They lost their mother to a Maverick raid on Area H ten years ago, and the lack of intervention on Slither Inc.'s part gave them a reason to hate the company. The truth behind it (along with the death of Giro by Serpent's hands) gives them a reason to search for Model W... and that's to destroy it.
    • Purprill in particular was part of the Maverick raid that killed their mother. As soon as Vent finds this out, he states that any qualms he might've had about fighting Purprill have instantly disappeared.
  • It Was a Gift: They call Model Z a "memento," in honor of Giro.
  • Kid Hero: In ZX, they both can't be any older than mid-teens. Puberty kicked in over the Time Skip.
  • Kirk Summation:
    Serpent: "If you're so confident in yourself, then let's see which of us is destined to rule the world!"
    Aile/Vent: "I don't care about ruling the world! If you're the Mega Man destined to rule the world, then I'm the Mega Man that's destined to save it!"
  • Made of Iron: In the opening cutscene, they survive both their bike exploding from Galleon shots in their face and the resulting long fall to the ground off the cliff caused by the blowback. Keep in mind, this is before they get Model X.
  • Off Screen Moment Of Awesome: In Advent, Aile/Vent stay behind to face off against the four enemy Mega Men while Grey/Ashe go to take down Albert. When it cuts back after Albert's defeat, Aile/Vent are still standing strong against them, only cutting off the battle to rescue the now-collapsed Mega Man Model A.
  • One Steve Limit: Don't confuse Aile with the character of the same name from Mega Man X: Command Mission.
  • Parental Abandonment: Both of their parents were killed by Mavericks.
  • Previous Player-Character Cameo: In ZX Advent. And like previous bosses, Grey/Ashe can copy their data and turn into Aile/Vent respectively.
  • Purely Aesthetic Gender: While Vent's and Aile's story in ZX are different via having different dialogue at various points and shifts in the narrative focus (Vent's story explores more of the backstory of ZX and its ties to the Zero series such as revealing that it was Ciel who made the Biometals while Aile's focuses more on the future such as the revelation that she and by extension Vent have ties to the Greater-Scope Villain, Master Albert. Plus, their relationship with Giro is slightly different between them.) the basic premise and levels of the game still the exact same between them.
  • Rapunzel Hair: As Mega Man Model ZX, both get it, although the hair is artificial. Their real hair becomes this in ZX Advent. Especially Vent.
    • Apparently, this was done as a way for both to honor Giro's memory, though it's more noticeable with Vent.
  • Reflective Eyes: After their transformation in ZXA, Grey (for Aile) or Ashe (for Vent) is shown in their eyes.
  • Schrödinger's Player Character: You're effectively choosing not who to play as at the outset of ZX, but who fills the blank role of protaganist. The other character is never mentioned in the story.
    • Advent continues this; if you play as Grey, you meet Aile and she saved the world in the previous game, and if you play as Ashe, you meet Vent and he saved the world, but you never meet the other two characters. It's made even more confusing by having one of the cipher cutscenes show both of them at the same time, which implies that the two of them at least at one point existed in the same continuity.
  • Screw Destiny: Both of them become proponents of this by the end of ZX, though Aile takes it to heart even more thanks to Giro's encouragement after she learns about her ties to the Greater-Scope Villain. Aile in particular goes on to hammer this home to Grey in Advent, who takes it to heart during his final confrontation with Albert.
  • Secret A.I. Moves: Averted in Advent. Everything they can do in their boss fight, Grey/Ashe can do as well. The only thing Grey/Ashe can't do is effectively chain certain combos of abilities together.
  • Sempai/Kohai: Vent uses "Senpai" to address Giro, at least in Japanese versions.
  • Short Tank: Aile, of course.
  • Shoryuken: An additional saber technique for Vent in ZXA. He can also fire a large Sword Beam when he does so.
  • Short Hair with Tail: Aile in Advent.
  • Superdickery: Their duel with the protagonists in Advent, which is pretty blatantly an excuse to get to fight the previous player characters. To be fair, though, Grey/Ashe's introduction boiling down to "I want that Model W, get out or get hurt" did extraordinarily little to communicate that they weren't another of Albert's Mega Men.
  • Sword and Gun/The Musketeer: As Mega Man Model ZX, their weapon is a Laser Blade that can transform into a chargeable Buster.
  • Sword Plant: An additional saber technique for Aile in ZXA, which also sends out 2 rocks to the left and right.
  • Theme Twin Naming: Their names are French for "wind" and "wing."
  • They're All Grown Up: Face it; post-time skip Vent and Aile have definitely come a long way from ZX. Vent is now a long-haired Bishōnen, and Aile is Ms. Fanservice.
  • Tomboy: Aile in the first game. More of a Ladette in the second, but we don't get much characterization in that one.
  • Transformation Sequence: Each get one in each game. In ZXA, Aile's is a good thirty seconds longer and involves a crapload of posing. Magical Girl Shout-Out, fanservice, or both? You make the call.
  • Twincest: Vent/Aile is quite a popular pairing in the fandom. Assuming they're actually related, of course.
  • What the Hell, Hero?: They give one to Fleuve when he expresses shock at them taking Model X with them to find Giro, angrily asking him if he doesn't care that Giro risked his life to get the Biometal to the Guardians and might still be in danger as long as they have it. Granted, Fleuve's reaction seems to have been one made in the heat of the moment, especially since Vent/Aile don't realize Giro is actually a Guardian himself with his own Biometal and thus more than capable of handling himself, but Prairie quickly puts a stop to the argument.
  • Wouldn't Hit a Girl: Subverted with Vent. He admits it's not in his principles to fight with Ashe, but due to the unfortunate misunderstanding, he has to if he wants to get to Model W.
  • You Killed My/Our Parents:
    • Purprill the Mandroid was responsible for their parents' deaths, according to Vent's story. Aile's story makes no mention, but if they are Half-Identical Twins, then it would apply to her as well.
    • As Giro was their Parental Substitute, his fatal wounding at Serpent's hands invokes a similar sentiment with Vent/Aile as well, as well as him being behind the attack that took their biological parents from them too.
  • You Remind Me of X: Rose eventually states that Vent/Aile remind her of "him" (all but stated to be Giro), while lampshading she knows Aile is a girl, but it's still the same feeling.
  • You Shall Not Pass!: Pull this on the enemy Mega Men at the end of ZXA to let Grey/Ashe fight Master Albert unopposed. Subverted when it's instead Model Z who tells Vent/Aile to go on and help Grey/Ashe.

Voiced by: Ami Koshimizu (JP), Maya (EN)
The female lead of ZX Advent. A Hunter in search of loot and fortune (or as she calls it, "booty"). Her ambush on the Raider's air fleet had her biting off a lot more than she ever hoped to chew — namely "The Game of Destiny" as well as Master Albert's fabrications and relation to her. Unlike most Mega Man characters, Ashe's buster fires only two shots at a time, though each shot is more powerful than normal.

Voiced by: Hiromi Hirata (JP), Peter van Gomm (EN)
The male lead in ZX Advent. A reploid youth who wakes up in an abandoned and mysterious laboratory with no memory of his past, Grey's quest to find out who he really is inevitably shoehorns him into "The Game of Destiny" and results in a very unexpected revelation.

  • Amnesiac Hero: He wakes up not even knowing his own name, and for a large part of the game his motivation is finding out who the hell he is and why the villains keep calling him "Defective".
  • Awful Truth: Both Atlas and Pandora state that when he learns the truth about himself, he will fall into despair and wish that he died ignorant. Thanks to Aile, though, by the time he does learn, he pretty much doesn't care and intends to take down Albert regardless.
  • Cannot Spit It Out: Model A seems to be suffering from Laser-Guided Amnesia at first, but by the time they reach Ouroboros, Master Albert says that Model A should have remembered everything by that point, namely the fact that Model A was created by Master Albert and that Grey is his backup body.
  • Character Development: Due to having no memories of his past, Grey's experiences during the events of Advent help shape his overall attitude and character. This becomes especially evident when one compares his zealousness to find out who he really is at the beginning of his Quest for Identity, to how after he meets Aile, he admits he's stopped caring about it.
  • Charged Attack: He can charge up a stronger Buster shot as Mega Man Model A.
  • The Chosen One: Even among The Chosen Many, Grey stands out because he was to be Albert's backup body in the event of the latter's death, and so was meant to be the one to obtain Model W's power. Subverted, however, due to both his incomplete brainwashing and the fact he was only the Plan B. By endgame, Albert willingly admits he would kill him without hesitation now that the Ouroboros was complete.
  • Cloning Blues: He finds out that he's Master Albert's defective backup body. He later decides that he doesn't care.
  • Color Character: His name is also reflected in his hair color.
  • Crossdressing Voices: In Japanese, much like Vent in the original.
  • Dark-Skinned Blond
  • Decomposite Character: If Ashe takes after Axl's personality, Grey takes more from Axl's backstory. He's an Amnesiac Hero of a kind of reploid different to current generation types, in addition to having a "family" connection with the main villain.
  • Fingerless Gloves
  • Flawed Prototype: Of Albert's backup bodies.
  • Gender Bender: Inevitable whenever he turns into a female Pseudoroid or Mega Man.
  • Goggles Do Nothing: The big cables on his back were supposedly used for transmitting power and/or brainwashing, but after he's released from the capsule, they're pretty much useless (aside from looking cool).
  • Good Scars, Evil Scars: Has a small scar running down the left side of face.
  • Guns Akimbo: As Mega Man Model A, especially in his Giga Crush ability.
  • Image Song: A vocal version of his first stage theme ("Destiny") appears on ZX Gigamix, titled "Believe in Myself."
  • Jerk with a Heart of Gold: Because he's technically "born" at the intro stage (and possibly because Pandora's going to kill him), he hasn't learned politeness yet, and thus, he talks rude to people, as The Sage Trinity and later Aile noted. However, he's ready to help everybody in need, because he's inspired by the Hunters who found him and brought him to the Hunters' camp.
  • Kid Hero: He's only physically 14 at the start of Advent, though depending on how long Albert was working on him, he could actually be older or younger.
  • Laser-Guided Amnesia: Due to the fact that he literally has nothing to remember. According to Master Albert's plans, Model A was supposed to fill-in Grey on the details should anything have happened to Albert.
  • Made of Iron: Survives an explosion that destroys the bridge he's standing on, falls an indeterminate distance down into the waters below the mysterious lab, and then is carried who knows how far and long in said water until he washes ashore outside Hunter's Camp, where he's rescued by Billy.
  • Name Amnesia: In the beginning of his story when he wakes up and states he doesn't remember anything about who he is, that includes his name. Pandora then warps in and tells him his name is "Grey", right before she states her mission to dispose of him as a "Defective." When the Hunter Billy asks him what his name is, all Grey states "at least that's what she called me."
  • Non-Standard Character Design: Grey stands out alongside other characters in ZX; he lacks civilian clothing, and his chestplate and shoes are armored, as if he was already partially Megamerged with Model A. Which makes some level of sense, given he was meant to get Model A in the first place.
  • One Of These Is Not Like The Others: Of all the playable characters in the ZX series, he's the only Reploid.
  • People Jars: He was inside one, before he was accidentally released in his opening cutscene.
  • Perpetual Frowner: He never smiles throughout the game, save for the ending.
  • Phlebotinum Rebel: He is a textbook Case C; if Mick and Robin weren't snooping around the labs, the Big Bad would still have his backup body. Pandora only added fuel to the flames of rebellion.
  • Post-Victory Collapse: After he defeats Albert, he faints due to fatigue. Aile rushes over to save him, but not before Model Z demerges from Aile's body to hold the Enemy Mega Men in place.
  • Power Copying: Taken to the next level via the copying A-Trans powers of Model A.
  • Protagonist Without a Past: Not that he had much of one to begin with, given he was "born" in that facility he woke up in.
  • Pursued Protagonist: Mimicking Zero in the first Zero game, he was sealed in an abandoned lab before being pursued by the Resistance (Zero)/the Hunters (Grey), and then they also grab a gun from a dead body.
  • Quest for Identity: He goes to the Legion HQ specifically to find out who he really is, but Thomas said that all the information pertaining to Grey was missing. Eventually, he knows that he's Albert's backup body. See also Tomato in the Mirror below.
  • Raised as a Host: He's actually built as Albert's backup body, designated as DAN-003. Thanks to the Hunters' unwitting interference, however, he's freed from his brainwashing process.
  • Red Eyes, Take Warning: After he's released from the capsule in the intro cutscene, it's shown that he has these, but they quickly turn into green eyes. Possibly has something to do with his incomplete brainwashing process.
  • Roboteching: His Homing Shot ability involves him targeting up to 8 enemies and then firing homing energy shots, one for each targeted enemy.
  • Schrödinger's Player Character: As before, Ashe is nowhere to be seen or heard of if Grey is chosen. Ashe's stage still appears in the map in Grey's story, but it can't be accessed.
  • Screw Destiny: This is his eventual response, with a bit of prior mentoring from Aile, to his Cloning Blues.
  • Smart Bomb: The Giga Crush ability.
  • Tomato in the Mirror: Subverted. After searching for long enough for who he originally was, Grey decides he couldn't care less about his original identity, if he even had one.
  • The Un-Favourite: More or less. His "dad" is indifferent to him and unlike his "siblings," Grey had no purpose in the Game of Destiny. He was just "Plan B."
  • Unwitting Pawn: Prometheus and Pandora used him so they can meet face-to-face with Albert and exact their revenge. Pandora even said "thank you" to him before Prometheus kills Albert. And then they try to kill Grey.
  • Walking the Earth: At the end of the game (before The Reveal), he decides on doing this, continuing on his quest to find out more about himself.
  • When He Smiles: The first time he ever visibly smiles is at the end of the game, first to Model A, then to Aile. After seeing his usually-scowling face for so long, it's both jarring and yet also heartwarming.
  • White Sheep: Due to the interruption of his brainwashing process.
  • You Are Number 6: Has the code number of DAN-003 (Dr. Albert Number 003). He's the third of Albert's creations, behind his "siblings," Prometheus and Pandora. This only gets revealed in the Drama Tracks, though.
  • White Hair, Black Heart: Subverted. He may be rude and gets annoyed easily, but he's influenced by the heroics of the Hunters and thus deeply cares about people. According to Pandora, he even was meant to have a black heart.
  • Would Hit a Girl: As shown by his battles with Atlas, Pandora, and Aile, especially the former two considering they're trying to kill him.


Voiced by: Yuuto Kazama
Vent and Aile's boss, he runs a self-titled carrier service that will deliver "anything, anywhere." Unassuming at a first glance, there is much more to him than meets the eye. Despite his uncanny resemblance to Zero, the two characters are not one and the same. Like Zero, however, he is this series' answer to Proto Man.

  • Becoming the Mask: A heroic variant. While it's stated in Aile's story that the Guardians's first commander was the one who requested Giro to look after the survivors of the Maverick incident (i.e. Vent and Aile), he comes to genuinely care for them, prompting his Heroic Sacrifice.
  • Big Brother Mentor: Acts as this for Vent and Aile.
  • Big Damn Heroes: Pulls this on the second boss of the game by leaping in from offscreen with a charged saber.
  • Bishōnen: Go ahead, look at him.
  • Brainwashed and Crazy: Thanks to Serpent and Model W.
  • Cool Bike
  • Cool Shades: As Mega Man Model Z.
  • Death by Depower: Voluntarily does this by giving up the source of his power in the Model Z Biometal, which is also the source of what's keeping him alive.
  • Expy: mentor, Rapunzel Hair, Mind Controlled to fight Vent/Aile, and a Sacrificial Lamb/Player Punch? Yeah, he definitely isn't like Zero, no siree...
    • They also share the same seiyuu, Yuto Kazama.
    • By extension this makes him ZX's Protoman
    • Prairie subtly lampshades this in ZX in Aile's campaign.
  • Fingerless Gloves
  • Helmets Are Hardly Heroic: Unlike the other Mega Men, his Megamerged form doesn't have a helmet. Perhaps that's a nod to Zero's broken helmet in the Ragnarok ruins?
  • Heroic Sacrifice: Gives up Model Z, the only thing keeping him alive at the moment, to make sure Vent/Aile can get out alive.
  • "I Know You Are in There Somewhere" Fight: When Serpent mind-controlled him to attack Vent/Aile, he/she tries to bring back his mind in the boss fight. It is a success... but then Serpent finishes him off.
  • Laser Blade: As Mega Man Model Z, of course. Interestingly, his is shaped more like a katana than the straight sword Vent/Aile get. In his boss battle, he can increase its size to BFS levels.
  • Multiple-Choice Past: A small but noticeable one between Vent and Aile's story is that in the former he claims he only recently got Model Z around the same time as Vent obtained Model X, while in Aile's story he freely admits he's had Model Z for years before this point, likely before he even met Aile. Noticeably, ZX Tunes confirms Aile's version of the story is the actual one, meaning he lied to Vent.
  • Parental Substitute: After their mom died in the Maverick raid in Area H, Giro took Vent/Aile in and raised them for at least a decade. While it is revealed in Aile's story that he was asked to do this by the Guardian's leader, he did legitimately grow into the role. That said, he seems to trust Aile more than he does Vent, as he's far more willing to be truthful to Aile (as shown by how he reveals his relationship with Model Z) and reprimands her for her attitude less than Vent.
  • Red Eyes, Take Warning: When Brainwashed and Crazy (thanks to Model W), his eyes glow red.
  • Retired Badass: He's a former member of the Guardians, according to Aile's storyline.
  • Sacrificial Lamb: He's introduced as Vent/Aile's father figure, as well as pretty well-versed in the world and quite skilled with his Biometal. All signs point to him being The Mentor figure over the course of the game. However, he dies at the end of the fourth mission which signifies the end of the first act, with his sacrifice providing Vent/Aile's major motivation for the rest of the game.
  • Sword Plant: One of his moves in the fight is to jam his saber into the ground and release pillars of light at set intervals away from himself.
  • Take Up My Sword: First with his relinquishing of Model Z, and a second time at the end of the game, where he gives Vent/Aile the mission to "guide this country to peace."
  • Talking to Himself: Yuuto Kazama voices both Giro and Model Z in ZX. Funnily enough, they're respectively the Expy and Legacy Character of Zero.
  • Theme Naming: His name is French for "weather vane," fitting in with Vent and Aile.
  • Trademark Favorite Food: Coffee, apparently.

    The Guardians

A paramilitary defense organization created by the people of the frontier regions. Their vow is to defend Innerpeace areas and discover the cause of Maverick outbreaks.

  • The Ace: Hareng is described as always aspiring to be this and he apparently does a pretty good job at playing the cool elite Guardian, but when he comes up short the persona tends to come unraveled.
  • Bridge Bunnies: There's 3 of them, named Gardénia, Tulip, and Marguerite.
  • Cool Airship: Guardian Base, which doubles as HQ.
  • Cowardly Lion: Congre is such a Nervous Wreck that if Vent/Aile approach him while Megamerged during the certificate exam, he'll teleport out in fright despite knowing who they are. Despite this, when the chips are down he'll dig in with the rest of the Guardians to save the innocent.
  • Gadgeteer Genius:
    • Flueve, more or less. He's Cerveau's Expy, right down to the Brainy Specs with Opaque Lenses and his role as the keeper of Data Disks. However, he's more or less the technical guy rather than actually building anything.
    • Silure and Anguille serve the more traditional role as the Guardians' major mechanic and mechanic assistant respectively. Both of them even provide missions for Vent/Aile to provide materials with which they can craft equippable chips.
  • Casanova Wannabe: Scombrésoce is described as always being a gentleman to the ladies, but any points he gets tends to be docked by how he has a bad habit of sticking his nose where it doesn't belong, which irritates his fellow Guardians.
  • Dark and Troubled Past: Several of them are hinted to have this. Rose in particular recounts how she watched a guy she liked suffer from his horrible injuries for two days before he finally died.
  • Fiery Redhead: Cédre is The Lad-ette with flaming red hair and totting around a BFG, offhandedly mentioning that Prairie keeps her on base specifically so she can keep an eye on the destruction she causes otherwise.
  • Proud Beauty: Cédre has a high opinion of her looks, and the first time talked to by Aile she'll claim Aile is "cute" but still nothing compared to herself. She does claim Aile could give Prairie a run for her money, though.
  • Put on a Bus: Despite their aid to Vent and Aile in the first game as well as the implications that Vent/Aile became full-time members after ZX (given how they're able to call up the Guardian Base for the assault on Ouroboros), none of them actually make a direct appearance in Advent.
  • Red Oni, Blue Oni: Carrelet and Anguille are described as this, but the interesting thing is they take traits of both that still contrast. Carrelet is an on-field fighter, passionate about his work, doesn't suffer those who don't put their best effort in, and puts his faith in logic. Anguille meanwhile is the on-ship mechanic assistant, usually reserved, tends to slack off and/or go overboard in showing off depending on the person, and gets quite emotional.
  • Red Shirt Army: Compared to the predecessors in the Resistance, however, they have a much better track record. They actually hold their own defending against Serpent's attempt to destroy their air base and Vent/Aile are only needed to destroy one airship and stop Prometheus from destroying their ship's generator. However, several of them lampshade around the end-game that if Serpent gets the Model W Core, they'll have no choice but to rely on Vent/Aile to win because they just don't have the firepower to handle that sort of monstrosity.
  • Spiritual Successor: Much like the Prairie = Alouette theory, there are many who believe that Fleuve is a considerably older Perroquiet from Zero. All of this factors into the belief that The Guardians were formed from The Resistance seen in Zero 4.
    • Because their role is to investigate Maverick attacks, they're also successors to the Maverick Hunters.
  • Tagalong Kid: Sardine takes this role, with his Secret Disk even noting he's the only child on the Guardian Base. He clearly looks up to the rest of them as his heroes.
  • Top-Heavy Guy: Thon is the largest and most muscled member of the Guardians, built like a truck and it's noticeable his legs (while decently muscled) are still rather thin compared to his arms and chest.
  • Theme Naming: The Bridge Bunnies are named after flowers; fitting with the name Prairie meaning "meadow." Most of the Red Shirts (and other members) are named after fishes; fitting with the name Fleuve meaning "river." All with French names.

Voiced by: Ryo Hirohashi
The current leader of The Guardians who took command after the original leader went missing during an investigation of an Outlands area. She hires Giro Express to transport the Biometals Model X and Model Z, and helps Vent/Aile on their mission to combat Slither Inc. and the Maverick attacks. Due to her appearance, memorabilia, and remarks made during the story (such as her being present when Ragnarok broke apart in the atmosphere), Prairie is heavily implied to be Alouette, Ciel's Kid Sidekick from Mega Man Zero.

    Master Mikhail
Voiced by: Chō (JP), Walter Roberts (EN)
The third member of the Sage Trinity. Seems to be the most venerable and down-to-earth member of the trio, given his shock and horror that Master Thomas plans to continue with Albert's work.

    Master Thomas
Voiced by: Hidekatsu Shibata (JP), Matt Lagan (EN)
The leader of the Sage Trinity. He and Mikhail provide assistance to Grey and Ashe in their journey to defeat the defector known as Master Albert. In The Reveal at the end of Hard Mode, it's shown that he disagreed with the method of Albert's work, but agreed with the desired outcome: to remake the world.

    The Hunters

A large group of bounty hunters, seeking to find relics of the old world and make fortunes for themselves, after the first group of them were inspired by an entrepreneur discovering pre-war technology and making it bignote . As ruins tend to be inhabited by Mavericks, they tend to do their jobs armed. As a result, they can hunt out Mavericks for money, in addition to finding lost tech.

  • Expy: They're essentially Guardians of the previous game, but wearing a different uniform and more informal.
  • Rag Tag Bunch Of Misfits: They can give off this impression, considering they seem to recruit from all ages, races, genders, and/or former occupations (at least one admits she used to be a bandit and Grey is able to receive a Hunter's License just by using the transerver in Hunter's Camp, though it's pointed out by Billy people can't even enter or leave the camp without one anyways and it would be awkward for Grey if he couldn't leave).
  • Red Shirt Army: The generic Hunter is almost this. They're the only kind of Hunter who don't have a unique design and the only ones who die on-screen, but they're still surprisingly competent for a Red Shirt: they can actually take out some of the low-level mooksnote , and in Ashe's intro, three of them are able to take on Prometheus and recover the Biometal offscreen.
  • Small Role, Big Impact:
    • Mick and Robin only show up in Grey's story for the prologue and get killed by the security, but if not for them, Grey never would have awakened before his brainwashing was complete and he wouldn't have gotten a gun to protect himself and shoot his way out of the lab.
    • Billy's biggest role is being the one to save a grievously-injured and likely nearly-drowned Grey after finding him near Hunter's Camp, yet not only does he save the young Reploid's life, his attitude of "just doing the right thing" is what helps shape a huge part of Grey's character going forward.
  • Spanner in the Works: In Ashe's intro, they manage to pilfer Model A right from underneath Prometheus' nose after Ashe gets downed by him, and in Grey's story, two curious Hunters die for it but ultimately allow Grey to break out and find his own path in life instead of remaining the backup body he was intended to be. This gets the chosen player character and Model A in the right place together to Megamerge outside of the Game of Destiny plans, and utterly throw the whole dang thing into chaos to save the world. Not bad for an Red Shirt Army that mostly stops being relevant after the prologue.
  • Uniformity Exception: Their uniform seems to be a visored helmet, jacket, Utility Belt, and boots, but those who call themselves Hunters and follow the uniform seem to be in the minority.



    Prometheus & Pandora
Prometheus voiced by: Daisuke Kishio (JP), Ryan Drees (VXA, EN)
Pandora voiced by: Shizuka Ito (JP), Rumiko Varnes (VXA, EN)

An enigmatic duo working for Serpent. While it appears that they're helping him revive Model W, they're really "the voices of Model W," aiming to expedite the "destiny of destruction." Despite being bested by Vent/Aile in ZX, they return in the sequel. Here, it's discovered that they are a pair of sibling Reploids created by Master Albert to serve as scouts for "The Game of Destiny." They were given a portion of Model W's power, keeping them permanently Megamerged. Additionally, Master Albert imposed a limit on the amount of time they could live in order to keep them under control, requiring them to keep going back for maintenance in order to stay alive. Loathing the man, the pair finally enacted their revenge on Albert and plan to destroy everything... only to learn that the Albert they killed was a dummy. Becoming his Unwitting Pawns, their pent-up, centuries-long feelings of hate and rage served to fuel Model W's resurrection. They were last seen at Albert's mercy in an exploding underwater base located underneath a volcano. Their deaths have yet to be confirmed.

  • All There in the Manual: The ZX Gigamix album shows them without their armor on.
  • Aloof Older Siblings: They only care about themselves and each other, and have nothing but disdain for their "younger brother," Grey. And there's, you know, trying to kill him.
  • Attack Drone: Pandora has 2 drones attached to her hair that can be used to fire off elemental attacks.
  • Attack Reflector: Prometheus can use his scythe to deflect blaster shots if he's rushing at the player during his fights. In ZX, he takes it a notch further by casually knocking Vent/Aile's Charged Attack right back at them when they try to shoot Serpent.
  • Ax-Crazy: Prometheus.
  • Badass Adorable: Pandora, although her "adorable" overshadows the "badass," especially in comparison to Prometheus.
  • Blood Knight: Prometheus is quite nihilistic, enjoying nothing more than mindless violence and a good fight. However, this may have been deconstructed after your fight with them in ZX Advent; he hints that his having to do senseless fighting was one of the reasons as to why he and Pandora wanted to betray and kill Albert in the first place.
  • Calling the Old Man Out: Prometheus indulges in quite a bit of this after he kills Albert's dummy body, laughing at the fittingness of Albert being murdered by his first Mega Man and lambasting Albert's "Game of Destiny" and grand plan of evolution with Model W and Mega Men as nothing but a farce and "epic sham".
  • Co-Dragons: For both Albert and (for a short time) Serpent.
    • Dragons With An Agenda: They play this role to Serpent, explaining why they leave him to his own purposes towards the end of ZX. And ultimately they prove to have similar feelings towards Albert, wanting nothing less than to just destroy the world to spite Albert's plans to remake it.
  • Chewing the Scenery: Prometheus chews enough scenery to make up for his sister's lack of it, especially near the end of Advent.
  • Climax Boss: In both games, Prometheus and Pandora are fought at pivotal moments in the plot that answer and raise more questions about the schemes of the villains.
  • The Corrupter: According to others, Slither Inc. began to change the moment Prometheus and Pandora came onto the scene.
  • Cutscene Power to the Max: When Prometheus uses his Sword Beam attack in cutscenes, it's either an incredibly damaging move that leaves the target on the verge of death or just a straight-up One-Hit Kill. In the actual boss fights, while it is a pretty powerful move it's ultimately not much more dangerous than the rest of his arsenal.
  • Dark and Troubled Past: From the game itself, it's implied that they've been suffering throughout their entire lives. If the drama tracks are anything to go by (see Flashback Nightmare below), it also shows them getting raided by Mavericks when they were younger.
  • Dark Magical Girl/Lady of Black Magic: Pandora. To a certain extent, anyway.
  • Emotionless Girl: Pandora. She's the exact opposite of her sibling, but no less dangerous or malicious.
  • Even Evil Has Loved Ones: For what it's worth, they do love each other immensely. This does not extend to their little "brother" Grey, however.
  • Evil Duo: They're a villainous Brother–Sister Team.
  • Evil Is Hammy: Prometheus all the way. Pandora is much more composed, to the point it seems that the reason she doesn't ham it up is because he's doing enough for two people.
  • Evil Laugh: Prometheus gets an epic one in the Japanese version.
  • Expy: Pandora is possibly a subtle one to Shion Sonozaki. Both wear their hair in a similar fashion, have the same shade of green, prefer white and blue (the hue is different) and both are driven to madness as the result of a rather nasty past.
  • Fire, Ice, Lightning: They cover all three, with Prometheus getting fire while Pandora gets ice and lightning.
  • Flashback Nightmare: Prometheus gets what appears to be this in the drama tracks when he's being rejuvenated in his capsule.
  • Grim Reaper: Prometheus.
  • Half-Identical Twins: There's some semblance, but you'd be hard pressed to be believe they're actually siblings if you didn't already know. Justified in that that were both artificially made.
  • An Ice Person: Pandora.
  • Just Toying with Them: Prometheus and Pandora are unique in that they have no "defeated" sprite aside from when they collapse after Model W drains their negative emotions. Even the enemy Mega Men have the decency to hunch over and hold their arms while panting in exhaustion when defeated. Prometheus' first battle is explicitly just to test Vent/Aile, Pandora's is to buy time for Serpent to recover Model W from Area M, their fight with Vent/Aile near the end of ZX has them just doing it to distract Vent/Aile from going after Serpent directly and let him get Model W to Slither Inc. and wake it up, and even their battle with Grey/Ashe in Advent has the fight breaking off after the Mega Man Model A yells at them this fight is just pointless, to which they agree.
  • Large Ham: The English release of Advent has Prometheus hamming it up before and after the player's battle with him and his sister. And even more in the Japanese version.
  • Leitmotif: "Trap Factory".
  • Mysterious Waif: Pandora. A notable evil example.
  • Not So Different: Prometheus tries to invoke this with Ashe, claiming they are "two peas in a pod" in that they both fight for Revenge: Ashe against him for almost killing her and her friends (and making a fool of her during their first encounter), and himself against Albert for using him and his sister for centuries. Ashe fires back he's got it wrong, prompting a mocking "The Reason You Suck" Speech from Prometheus about she's "playing" at being a hero when she's not.
  • Out-Gambitted: They played along with the Game of Destiny knowing that it would eventually allow them to get close to Albert and exact their revenge. Unfortunately, not only was the Albert they killed merely a decoy body, but hundreds of years of pent-up hatred proved to be exactly what all the Model W's in the room needed to activate and form Ouroboros.
  • People Jars: Each have one in the Mysterious Lab stage. It's used for daily maintenance, seeing as their days are numbered.
  • Playing with Fire: Prometheus, natch.
    • Flaming Skulls: One of his attacks in the first game summons four of these to the corner of the stages, and each of them will fire small fireballs at you. It's hard to dodge, but you can destroy the skulls, reducing the difficulty.
  • Power Floats: Pandora is almost always seen floating. Prometheus only floats when he uses area attacks.
  • Prehensile Hair: Prometheus. Yes, that's his hair he's using to attack you.
  • Psycho for Hire: Prometheus.
  • Psycho Prototypes: To Grey, although he was intended to become just like them.
  • Recurring Bosses: They're fought multiple times, both separately and together, in both games.
  • Purple Is Powerful: Prometheus wears purple armor and is most certainly one of the strongest Mega Men running around.
  • Rapunzel Hair: If the brief shot of them before being permanently bound to fragments of Model W is anything to go by. After the merger, Prometheus always has it, and uses it to kill you.
  • Red Baron: "The Reaper" or "Death" for Prometheus. Suffice to say, he lives up to that nickname. One of the Gigamix drama tracks even put a small emphasis on this.
    • Pandora gets the moniker of "The Witch." Her moments are fewer than those of her bro, but Pandora is just as much of a threat as Prometheus is.
  • Red Eyes, Take Warning: Ohhhhhh yes.
  • Red Oni, Blue Oni: The hammy, Ax-Crazy Prometheus is the red oni, and the stoic Pandora is the blue oni.
  • Scythe And Sorcerer: Prometheus is the scythe who prefers getting up close and personal, while Pandora is the sorceress who attacks with the elements from a distance.
  • Shapeshifter Mode Lock: They're permanently bound to Model W.
  • Shock and Awe: Pandora.
  • Sibling Yin-Yang: Prometheus is loud, boisterous, and all too willing to express his joy at fighting and killing. Pandora is quiet, talks very little, and prefers to go about fighting and killing in a calm manner.
  • Simple Staff: Pandora.
  • Sinister Scythe: Prometheus.
  • Slasher Smile: Prometheus' default expression.
  • The Starscream: They fully intended to destroy Albert when the time came. And they did... just not the one they expected.
    • The Dog Bites Back: Their motivations for wanting to destroy Albert were closer to this, as they had been abused and underwent constant suffering.
  • The Stoic: Pandora is soft-spoken and generally not open about her emotions.
  • Suicide by Cop/I Cannot Self-Terminate: Prometheus and Pandora's choice of words before fighting Gray/Ashe strongly implies that they want them to kill them in battle.
  • Theme Naming: Named after two of Saturn's moons, as well as two mythological Greek deities; Prometheus (the god who introduced man to fire) and Pandora (who opened up the quintessential Sealed Evil in a Can, allowing all of the repressed, negative emotions to plague mankind).
  • Those Two Bad Guys: Though far deadlier and seriously played than most examples.
  • Villain Takes an Interest:
    • Prometheus shows this towards Ashe, as while he always dismisses Grey as a "Defective" and a pawn, his talks with Ashe reach a more personal note, even invoking a Not So Different moment in that they're fighting for revenge (Ashe against him, him against Albert). Not that it stops him from trying to kill her once she leads him and Pandora to Albert.
    • Less obvious with Pandora, but she seems to have a similar interest in Grey, having longer conversations with him than with Ashe. Again, not that it stops her from trying to kill him once he leads her and Prometheus to Albert.
  • Woobie, Destroyer of Worlds: Despite appearances, they spent a long time fuming at the fact that they were made to be slaves for Albert's Game of Destiny. Prometheus's Famous Lastwords, before he and Pandora are royally owned by Model W, were a long rant about how pointless Albert's goal was, and that he might as well destroy the whole world thanks to the pain of what he and his sister had to endure.
  • Worthy Opponent: Prometheus seems to view Vent/Aile as ones, fighting them (particularly in Aile's story) in order to test if they're worthy of being part of the Game of Destiny and expressing approval after their battle concludes.
  • You Gotta Have Blue Hair: Prometheus has blue, Pandora has green.
  • Your Days Are Numbered: Wonder how in the hell Albert got these two to listen to his plans after torturing them for much of their youth? He intentionally made it so that, after he fused them with Model W, they would have an extremely short lifespan and would need regular maintenance to survive. Of course, they eventually decide they'd just kill everyone before dying themselves...
    • Stalked by the Bell: There is a literal counter on their capsules that is constantly ticking. If they're not back in the capsules by the time it's done...well...
  • You Have Got to Be Kidding Me!: Prometheus really tears into what he thinks of Albert's plans for the world, loudly calling it all out as the world's biggest joke.
    Prometheus: It was all a farce! Albert prepared everything in this world according to his own plan! He said Mega Men are the natural evolution of Man? Don't make me laugh! What an epic sham! I'm going to demolish this whole wretched world!

The head of Slither Inc. in the first game. Formerly a member of The Guardians, his encounter with a Biometal Model W fragment drove him insane and filled him with a burning desire to awaken the true Model W Core. To do so, he sacrifices Cyber Elves filled with the power of fear, which he creates by killing humanoids through what seems like random Maverick raids. He succeeds in reviving Model W, but the resurrection is short-lived. As Serpent dies, he declares all of humanity to be Mavericks for stopping progress.

  • Animal Motifs: May be averted, despite having an animal name.
  • As Long as There is Evil: In his Final Speech, he proclaims that as long as people — humans and Reploids alike — have something called a "heart," hatred will always lurk within them, and that those who refuses the idea of change are the true Mavericks.
  • Attack Its Weakpoint: In his second form, depending on the phase, you have to attack different weak points. The first is his head, the second is his shoulders, the third is the crystal in the middle of his "lower face".
  • Badass Longcoat
  • Big Bad and Final Boss: Of ZX.
  • Corrupt Corporate Executive: Head of Slither Inc., a massive Mega-Corp that covers both private military and energy production, and also a maniac who wants to sacrifice thousands of people to obtain godhood.
  • Dare to Be Badass: A villainous example. When Vent/Aile get their Heroic Second Wind against him after he goes One-Winged Angel, he challenges them to the final fight by declaring their battle will decide which of them is the Mega Man destined to rule the world. Vent/Aile reply they have no intention of ruling the world and they're the Mega Man who will save it from him. Cue final boss music!
  • Death from Above: One of his second form's attacks is him summoning 4 meteors from above that leaves small flame projectiles on their wake that try to home in on you. They're destructible, however.
  • Discard and Draw: In his second form, he starts the first phase with three attacks. When he goes to the second phase form he loses one of them but gains three new ones. By the third and final phase he stops using any of the attacks from his first phase, but keeps all the moves of his second phase while adding two new moves.
  • Driven to Madness: The original leader of the Guardians specifically notes that upon encountering the Model W fragment, Serpent grew obsessed with it until he finally lost his mind and slaughtered the recon unit to take it for himself.
  • Evil Redhead: More pink-red, but still very much evil.
  • Evilutionary Biologist: Albeit not to the scale of Albert.
  • Expy: His physical appearance, "evolutionary" sentiments, and his past as a member of a peace-keeping force meant to fight Mavericks before becoming corrupted are highly reminiscent of Sigma. Serpent even belts out Sigma's "evolution requires sacrifice" line during his Motive Rant.
  • Final Boss Preview: He's first seen mind-controlling the injured Giro, and then he introduced himself after he strikes Giro down again (after you fight Giro as the boss).
  • Fallen Hero: Was once a member of the Guardians, and judging by what little glimpses we get into his past as a Maverick raid survivor and the fact that it was exposure to Model W that drove him insane and evil it can be reasonably inferred he legitimately wanted to make things better for people given his own history. Then he was part of the recon unit that first encountered Model W, and the rest is history.
  • Finger Gun: He can fire spreads of energy shots from his fingertips.
  • Freudian Excuse: Aile's story, as well as Aeolus' cipher in ZXA, suggest that the reason he ended up being affected by Model W is because he was a Maverick raid survivor, and that he was afraid of his past. Having a trace of Albert's blood sealed the deal, though.
  • Gemstone Assault: In his second form, he can create growing crystals and then smash it; its debris can damage you.
  • Giant Hands of Doom: He employs these in his second form's third phase. They can create damaging crystals or fire energy shots.
  • Ground Pound: His first form has a move where he teleports directly above you and then tries to smash you with his feet. In Hard mode, this move also fires off spreading energy shots.
  • Humans Are Bastards: He wholeheartedly believes that so long as humans hold emotions in their hearts, they're no different from the Mavericks, being just as destructive as they are.
    Serpent: "The destiny of destruction... Still awaits... So long as you have hearts, hate will lurk in the shadows. You who possess the wellspring of emotion known as the heart... You are the true Mavericks!"
  • It Is Pronounced "Tro-PAY": According to the Japanese spelling, he goes by the French pronunciation, "Sair-pahn."
  • Jerkass Has a Point: Serpent is aware of the troublesome trend in the series' canon to the point it's nearly Lampshade Hanging: between the advancement of humans and machines, conflict breaks out, and in every generation, ever since the original, a hero rises to stop the fighting. The trouble is, the hero is motivated by protecting what they personally cherish and avoiding the pain of loss, and in doing so, they fail to actually diffuse the conflict, but cause it to be stuck in an ongoing limbo. In Serpent's opinion, even if it must be done through destructive and monstrous means, the world's doomed unless it can more forward already.
    Serpent: *To Vent* The Mega Man "destined to save the world"? Unchanging life... A world devoid of the light of hope. What's the point!?
  • Large and in Charge: By far the biggest Reploid in both games, and is the Big Bad and Corrupt Corporate Executive of the first.
  • Laughing Mad: His reaction as Model W's core is enveloping him into its system.
  • Life Drain: In his second form, where he fires 2 moving crosshairs that tracks your position; if you get hit, he'll extend an energy line that drains your health. Mash directional buttons to escape!
  • Lightning Bruiser: Serpent's first form on Hard mode is this Up to Eleven, and is among the most difficult boss fights in the whole franchise. Most of his attacks are sped way up or have extra range by extension, demanding sharp reflexes and careful positioning to avoid having your tiny lifebar shot to nothing. It's essential to memorize his attack pattern and where his blind spots are after attacking (and he'll probably be killing you enough times for you to find a rhythm). The trouble is, even after you get it down pat, the pressure is still on to not get hit because he's a Sequential Boss, and you're carrying any damage taken into the next round. Have fun.
  • Light Is Not Good: His Megamerged form is clad in armor of white and gold with orange spikes, and this coloration carries over in his One-Winged Angel form. He's also a Villain with Good Publicity with delusions of godhood.
  • Luke, I Am Your Father: Tells Aile that "the blood of the creator of Model W" runs through her veins. Come ZXA, we find out that it's Master Albert. Though it's not because they were actually related, as it was because Master Albert donated some of his blood to Maverick survivors as part of his plan (except for Ashe, as she is the legitimate descendant of Albert himself).
  • Names to Run Away from Really Fast: A man named Serpent is not going to be a good guy.
  • One-Winged Angel: Yup, a final boss staple. In his case, he achieves it by merging with the newly-awakened Model W core, becoming a giant Mechaniloid figure.
  • Orcus on His Throne: After getting the passwords from Model X and Model Z, he spends most of the game unearthing Model W while Vent/Aile rush to defeat his Pseudoroids to get the other Biometals while sending occasional forces against the Guardians. Once he has it, though, he doesn't bother leaving Slither Inc. because he was waiting for Vent/Aile to show up so he could absorb their hatred for him to wake it up.
  • Painfully Slow Projectile: His first form has a move where he shoots a very slow-moving Energy Ball that can be repelled back at him by enough shots.
  • Sequential Boss: Continuing the tradition. In Round 1, he Megamerges with Model W in a traditional manner (akin to the protagonist's ability). You defeat him just in time for Model W's core to awaken for Round 2. Even in Round 2, he can expand his form 2 more times.
  • Shoryuken: One of his first form's moves.
  • Slide Attack: In his first form a-la Copy X (of Mega Man Zero).
  • The Social Darwinist: He even pulls out the iconic (and frequently misunderstood) "Survival of the fittest" line.
    • Well-Intentioned Extremist: He states that he wishes to evolve the world rather than destroy it. In addition, he tells Vent that he wishes to remove pain and suffering from the world. His methods for doing so? Model W.
  • Stationary Boss: His One-Winged Angel form doesn't move since its lower body is connected directly to the floor with no feet. Not that it matters much since he has specific weak-spots that have to be hit with each life-bar knocked off, and most of his attacks can cover large portions of the room.
  • Start of Darkness: Was a member of the Guardians... and then he encountered Model W, causing him to wipe out his entire group (minus the leader).
  • Straw Nihilist: After Vent/Aile beats him for the final time, Serpent tells him/her that his fight to protect the ones he/she loves is pointless, as life will just go on in the cycle of peace and war.
  • Strike Me Down with All of Your Hatred: Tricks Vent/Aile into doing this to complete Model W's awakening.
    "The emotion driving you now... That emotion is not bravery... It's not born out of some sense of righteousness... It's hate. Your hate for me and everything I've taken from you!"
  • Super Mode: His first form also has the Overdrive Mode. He moves much faster in this mode.
  • Übermensch: How he sees himself, believing that as a Mega Man he has the right to rule and dictate the course of the world with Model W's power as a "shepherd". In fact, he believes all Mega Men should aspire to be this, scornfully stating to Giro and Vent/Aile near the beginning after crushing them that their weakness is proof that not all Mega Men are fit to rule and his final boast to Vent/Aile before they battle his One-Winged Angel being a challenge to see which of them is destined to rule the world.
  • Unperson: Despite having once been a Guardian, Prairie is in just as much shock at the revelation as Vent/Aile, as they have no records of that in their HQ. It's implied Serpent or one of his associates hacked and deleted all that information.
  • Unwitting Pawn: Subverted. He appears to have known something about Albert and his plans, judging from taunting Aile that she has the blood of the man who made Model W.
  • Villain with Good Publicity
  • With Great Power Comes Great Insanity: Yup.
  • Woobie, Destroyer of Worlds: A large part of his character was from being an implied orphan from a Maverick attack, and it is strongly implied (although he denies it) that he suffered from intense fear from that past, evidentially leading to his insanity. In addition, in the Japanese version, when denying Vent's retorts to Serpent, Serpent sounded a bit melancholy.
  • You Killed My Father: Not directly, but it is implied that Serpent arranged for Vent and Aile's parents to be killed.
  • You Will Not Evade Me: His second form can create a black hole to pull you in (or alternately push you away).

    Master Albert
Spoilers! Click here to see his true body 
Voiced by: Yoshito Yasuhara (JP), Jack Merluzzi (EN)

The Big Bad of ZX Advent. Starts off as one of the good guys until it's revealed that he had been working on Model W even before the events of the first game, but his intentions become clear awful quick. He lives up to his namesake, and goes on to try to reset the world, with himself at the reins.

  • Actually a Doombot: Prometheus kills Albert when he and Pandora show up in Albert's underwater base. Then after they fought Grey/Ashe, their emotions are suddenly sucked into the Model Ws in the background. Turns out, the Albert that Prometheus killed was a decoy.
  • Affably Evil: More so "affable" before The Reveal. Always evil. Notable in that he remains genuinely affable towards Ashe even after he reveals himself to be the Big Bad, while in Grey's story he belittles and constantly looks down on him instead.
  • All According to Plan: After he has the negative emotion of Prometheus and Pandora sucked into the Model Ws in the background, awakening them and forming the Ouroboros, he says:
    Just as I planned!
  • All Your Powers Combined: As Mega Man Model W (fittingly referred to as the "Ultimate Mega Man"), he uses Model A's Homing Shots, Model ZX's Charge Saber, Model H's Plasma Cyclone, Model F's Ground Breaker, Model L's Freezing Dragon, Model P's Cross Star, Prometheus' Beam Scythe, Pandora's Teleportation, and Chronoforce's Time Bomb (although it's used only to counteract and nullify the player's own Time Bomb). His "bits" even glow with the appropriate color for each borrowed attack.
  • Attack Drone: Controls several bits in his Megamerged form, all of which are capable of emulating attacks from other Mega Men.
  • Badass Bookworm: Whereas Thomas and Mikhail are depicted as carrying a sword and a knife, Albert's fake body is usually seen holding a book.
  • Big Bad and Final Boss: For ZX Advent.
  • Bishōnen Line: Goes from a three-headed mechanical dragon, to the vastly-powerful, nigh-angelic Mega Man Model W.
  • The Chooser of The One: More like The Chooser Of The Many, but he still qualifies.
  • Continuity Snarl: His origin story for Model A ("A" as in "Albert," not "Axl"), as well as whether or not Master Albert is controlling Model W or vice versa. These plot points (especially the former) have been eating at fans to this day, leading to a jungle of Epileptic Trees. For example, the fact that Albert clearly says "Axl Bullets" while firing his Homing Shots does not help. Doesn't look like any of this will be resolved, either.
  • Cool Chair: Before the fight against him, he is seen sitting on one, before it transforms into the aforementioned three-headed dragon.
  • Crosshair Aware: He has an attack in which he sends out a crosshair which tries to follow the player and shoots at certain intervals.
  • Damage-Sponge Boss: First half of the final battle. His throne tank is such a Stone Wall that it doesn't even get a lifebar. The goal is to cherry tap it in the gut as fast as you can mash the fire button, whenever you get the chance, until it explodes.
  • Defiant to the End: Even as he lays defeated before Grey/Ashe and hears their Kirk Summation, Albert still has enough strength left to spitefully insult and tell them they can "rot" in the "peace" they've achieved before he explodes.
  • Devil in Plain Sight: When the character designers name you after the first villain of the entire franchise, your chances of being on the heroic side of the spectrum don't look too good, eh? Sadly, no one in the game takes note of this connection.
  • Evil All Along: He was actually researching on Model W since long before the events of the games, as Master Thomas explains.
  • Evil Counterpart: Could be considered one to Grey/Ashe, seeing as his abilities with Model W (see All Your Powers Combined above) are identical to those of Model A's, but stronger and more versatile. Justified in that Model A was created to mimic the power of Model W as a backup plan in case Albert was somehow incapacitated.
  • Evilutionary Biologist
    Albert: "I wanted to be the ultimate... To be at evolution's extreme... as one of the Sage Trinity, but above all, as a scientist. At evolution's extreme, there is emptiness and misery."
  • Expy: Officially of Dr. Albert Wily, although most of his personality and goals are more similar to those of Albert Wesker.
  • Eyes Always Shut: Until The Reveal, where it's revealed that his eyes are red with black sclera.
  • The Faceless: As Mega Man Model W, thanks to his helmet. All that you can see are his Glowing Eyes of Doom (well, at least until right near his death).
  • Faux Affably Evil: Towards Grey after his reveal as the Big Bad. While speaking with a polite demeanor towards him during these times, he also takes the time to constantly belittle and taunt him as well.
  • Gambit Roulette: An epic one (of the Ancient Conspiracy variety) spanning centuries. He's just that good, even though it didn't quite come to fruition.
  • Genocide Backfire: Subverted: Albert deliberately arranged the Maverick Raids to spare a few people so that he'd then donate his genes to them and thus have them participate in the Game of Destiny.
  • A God Am I/Godhood Seeker: Spent centuries to try and make it reality too. Grey and Ashe's response to him upon his defeat is essentially to tell him that for all his "godly" power, he still couldn't even change the destiny of one simple mortal.
    Albert: "I don't think I'm a god. I AM A GOD!"
  • Ground Punch: In his second form he can form his bits into the shape of a fist, which he then brings down to the ground to create damaging flame pillars.
  • Hoist by His Own Petard: Whether it is by Grey or Ashe's hands, Albert is defeated by his own "backup plans" and Model A.
  • Idiot Hair: He sports one. His true form has a larger one.
  • Irony: Created the Game of Destiny for one Mega Man to stand tall among them all, though he'd effectively rigged the 'game' to come out on top for his own ends. He then gets thrashed by the "victors", Gray/Ashe and Model A, the former one of his own "failed" backup bodies / his own great-grandchild, and the latter being his backup information and data of an earlier Model Albert gone through a Heel–Face Turn. Albert unwittingly played himself.
  • Large Ham: Damn straight. Must have been where Prometheus got it from.
  • Luckily, My Shield Will Protect Me: Uses several Model W fragments to deflect Grey/Ashe's attacks during The Reveal. As Mega Man Model W, he is surrounded by several Model W-esque bits that must be destroyed before you can damage him. Said bits also double as his method of attack, including forming a BFS.
  • Luke, I Am Your Father: An interesting variation on this trope: Most of the Mega Men that are encountered, including the protagonists in the previous game, were able to Megamerge not only because they survived Maverick Raids, but because Albert altered their DNA with his genetic code, which allowed them to Megamerge. However, Ashe was the only one whose DNA can be traced to Albert that wasn't due to genetic tampering, meaning her familial relationship to Albert was legitimate. Played completely straight with Grey, however.
  • Mad Scientist: Shades of it.
  • The Man Behind the Man: It's all but directly stated in Aile's story of ZX that Albert (via Prometheus & Pandora and Model W) was manipulating Serpent.
    • Unwitting Pawn: It's also implied in Ashe's story that Albert may be manipulated by Model W, his "creation," no less.
  • My A-Trans Is Better Than Yours: Possesses the "real A-Trans", allowing Albert to be able to change himself into the forms of those whose souls and negative emotions were absorbed by Model W. In addition, he does not even need to transform to utilize said powers (see All Your Powers Combined above). As Albert explains himself, Model A's A-Trans is a pale imitation.
  • Name's the Same: Shares his first name with another Capcom Mad Scientist Magnificent Bastard who plans to use Ouroboros to reset the world and take his place as a god. Maybe Model W stands for Model Wesker?
  • Offing the Offspring: Fully intended to do so with Grey (his robotic creation) and/or Ashe (his legitimate descendant). On the topic of Ashe, it's also heavily implied that he was the one who arranged for Ashe's parents, who likewise are most likely Albert's descendants as well, to be killed in a Maverick Raid.
  • Orcus on His Throne: After being revealed, he spends most of the game in his undersea secret base letting his minions feed and collect the Model Ws to send them to him, just waiting for Grey/Ashe to get the data necessary to get his coordinates. This is because he needs them to lead Prometheus and Pandora to him, so he can use their pent-up hatred of him to wake up all the Model Ws at once. After that, he still keeps waiting, though this time it's because he wants the chance to stroke his own ego about how his "spare ultimate Mega Man" (Grey) and his unexpected descendant (Ashe) managed to get so far and prove that his plans would have succeeded even if he died, and so he can kill them personally.
  • Ouroboros: His grand plan to unite all of the Model W fragments creates this. Its "cycle" symbolism is reflected on its purpose, to be used by Albert to Restart the World.
  • People Jars: His original body (DAN-000) has one.
  • Pet the Dog: An extremely, extremely small one when he expresses sympathy and regret over having to do in Ashe as she's his last living descendant. He has no such love for Grey, though, seeing him as a backup plan that has lost its use now that Ouroboros is complete.
  • Power Floats: In the cutscene of the reveal about him being the villain, he floats away using Model W. Later in Ouroboros, he slowly floats up as he transforms and the artificial sky breaks around him.
    • And during the battle with his Model W form, the only way to have Albert touch the ground is to forcibly introduce him to it.
  • Power Gives You Wings: As Mega Man Model W.
  • President Evil: As one of the Sage Trinity, the ruling power of Legion.
  • Rapunzel Hair: In his true body, given that he's now only the size of Grey/Ashe, but retains his hair's length.
  • Really 700 Years Old: He is at least a few centuries old, and Ashe is his descendant. Presumably his long life is due to being a cyborg.
  • Restart the World: This is his motivation for using the Ouroboros, as he planned to destroy the world and then recreate it, with only leaving the Mega Men as the only ones worthy to live in his new world.
  • Sequential Boss: First his throne turns into a giant three-headed mechanical dragon armed to the teeth. When you smash that contraption, he just emerges from the rubble unscathed, continues his self-serving monologue, and Megamerges with Model W.
  • Shielded Core Boss: As Mega Man Model W. He has a forcefield which you need to destroy by damaging it enough; only then can you do damage to him. He does regenerate the forcefield after a short time, so give it all you've got once the forcefield is down.
  • Strike Me Down with All of Your Hatred: Yet again, this time done to Prometheus and Pandora. Their hundred years of pent-up hatred and suffering got used to activate lots of Model W fragments to form them to Ouroboros.
  • The Social Darwinist: Not to the extent of Serpent, but it's definitely there. Either that, or he's contemplating on whether or not he'll be a Straw Nihilist.
  • Teleport Spam: After his shield goes down, he'll often do this.
  • Tempting Fate: When Grey and Ashe finally arrive at his secret base and see the hundreds of Model W cores, Albert gloats that he spent far too much time preparing for his plan that he would be inconvenienced by the loss of a few Model Ws. Then Prometheus and Pandora pop in and, after some banter, the former murders Albert right then and there. Subverted, however, as that was his dummy body and Prometheus and Pandora played right into the final stages of his plan without a hitch.
  • Tornado Move: He can create a pair of tornadoes in his battle form, taken from Model H's power.
  • Treacherous Advisor: As one of the Sage Trinity, he held Thomas and Mikhail's ears for centuries, using both his own power and the respect the two had for him to help further his plans.
  • Underestimating Badassery: He vastly underestimates Ashe's and especially Grey's skills and determination to stop him, and pays for it when either of them defeat him at the end of the game.
  • Villain Takes an Interest: Expresses a desire to see Ashe's development and watch her grow as a Mega Man, likely due to the fact she's the only piece he never saw coming.
  • Villain with Good Publicity: Unlike Serpent, however, he himself reveals his plans even before the halfway point of the story, making the "good publicity" part null.
  • Voice with an Internet Connection: For all of one mission prior to revealing himself as the Big Bad.
  • Voluntary Shapeshifting: As with the heroes who wield Model A, Albert can use his own A-Trans, including into the various Pseudoroids throughout the game. However, he never utilizes this ability during his boss fights as with the full power of Model W, he doesn't need to transform into someone else to use their powers as shown by utilizing Chronoforce's Time Bomb.
  • Wave-Motion Gun: As Mega Man Model W, he can fire two of these from the background to the left and right of the boss stage, and will slowly converge to the middle. You can try to jump at the right moment, or shoot one of the beams to push it back.
  • Well-Intentioned Extremist: His pre-final battle speech implies that the reason he decided to use Model W was because he wanted to stop people from fighting among themselves. The irony is positively ludicrous — how big is Advent's Gambit Pileup?
  • With My Hands Tied: His real body appears to be in a restraining jacket. It doesn't stop him from duping Prometheus and Pandora, though. He finally breaks out of it when he Megamerges.
  • You Gotta Have Blue Hair: Blue hair by default. When in his second, original body (DAN-000), it's freaking magenta.

    Enemy Mega Men
Clockwise from top: Thetis, Atlas, Siarnaq, and Aeolus
Aeolus voiced by: Yuki Tai (JP), Eric Kelso (EN)
Siarnaq voiced by: Wataru Hatano (JP), Jamie West (EN)
Atlas voiced by: Hitomi Nabatame (JP), Claire O'Conner (EN)
Thetis voiced by: Hisayoshi Suganuma (JP), Dillon Font (EN)
A group of mysterious youths who play "The Game of Destiny" to determine who will be the king of their world. They are the new holders of Models H, F, L, and P, which were stolen from Vent and Aile prior to ZX Advent. Each Mega Man has their own reason for indulging in Master Albert's fanatical game, a bit of a Psycho Rangers version of a Freudian Trio, plus one odd man out. They are:

  • Affably Evil: Thetis. He's a genuine Nice Guy, and the only one of the quartet who is actually friendly towards Grey/Ashe. If it wasn't for the extremes he went to accomplish his admirable goals, he'd probably be a straight-up hero.
  • Airplane Arms: Siarnaq's running and dashing animation, unlike the other Mega Men (who ironically use Ninja Run instead). Being Limp and Livid has something to do with this.
  • Ambiguously Human:
    • Both Aeolus and Atlas have hair obscuring their forehead, so we don't know if they have the red marks that confirm them as Reploids. At the very least, Atlas is implied to be human (as she's an orphan).
    • Thetis, on the other hand, does have a Reploid mark, yet Grey refers to him as human at one point. That said, given the context (where Thetis attacked a highway of innocents to feed the Model W fragment located there) Grey might have meant it in the context of "why would you kill fellow living people", which is reinforced by Thetis retorting that he and the others aren't humans, but Mega Men.
  • Ax-Crazy: Siarnaq has shades of this, mostly due to his bout of Laughing Mad as seen below.
  • The Beautiful Elite: Aeolus has shades of this, coupled with his Social Darwinistic tendencies.
  • Bizarre and Improbable Ballistics: Atlas can alter her projectile trajectories with her Buster Edit ability. The trajectory can be seen and predicted with red squares that appear on the screen.
  • Blade on a Stick: Thetis' weapon.
  • Blood Knight: Considering that her goal is to force evolution on mankind by starting a perpetual war, Atlas falls into this trope. No wonder she's paired up with Model F.
  • Blow You Away: Aeolus.
  • Boobs of Steel: Atlas' bust is noticeably bigger than the other females, and she's physically the strongest of the Mega Men.
  • Call-Back: Their attempt to gang up on Grey/Ashe right before the Final Boss almost exactly mirrors a scene from the original Mega Man Zero.
  • Ceiling Cling: Siarnaq is able to do this and Platform Cling.
  • Cool Sword: Aeolus carries one around in his normal form. It adds to his "noble" image and he unsheathes it as part of his transformation sequence.
  • Dark Action Girl: Atlas. She has the Biometal of the Guardian who loves to fight the most, after all.
  • Dark and Troubled Past: Atlas is an orphan due to the constant wars that plagued her homeland. As for Siarnaq, see Left for Dead below. All of them have been survivors of Maverick raids as well.
  • Desperation Attack: All four have one which they start using once they hit half-health.
  • Dual Wielding: Aeolus, with Laser Blades, mimicking Harpuia.
  • Elite Four: With Master Albert as the Big Bad and Prometheus and Pandora as Co-Dragons over them.
  • Enraged by Idiocy: Aeolus has little patience for those he views as fools and idiots, outright stating his goal is to kill all unintelligent people in the world to keep them from causing conflict due to their fears and foolishness overriding common sense.
  • Enemy Mine: There Can Be Only One! The four aren't friends, and would probably try to betray the others in their quest to become the Mega Man King. They appear to pull this again with Master Thomas. Could result in an Enemy Civil War.
  • Evil Counterpart: In many ways, they're essentially "The Four Guardians as full villains rather than Anti Villains."
    • Aeolus and Harpuia are Dual Wielding green-clad swordsmen who use lightning and wind powers. They both have very cold and to-the-point demeanors when interacting with others and are very prideful in their abilities, wanting nothing less than to terminate those they view as threats to the world. However, Harpuia's coldness masked a person who genuinely wanted to protect the innocent and weak from evil and uphold justice, while Aeolus' only serves to highlight his dismissive nature of "fools" and his desire to eliminate them from the earth for his brand of justice.
    • Atlas and Fefnir are battle-loving red/orange-clad soldiers who use fire and explosives. They are both very aggressive and value strength, wanting to improve humanity. However, Fefnir fought for the thrill of battle itself and to let humans live in peace, while Atlas' past has made her hate weakness and she wants to improve humanity by throwing it into a perpetual war.
    • Thetis and Leviathan are halberd-wielding blue-clad underwater fighters who use ice powers. They both always have a smile on their face that helps mask their darker impulses, and they tend to act the most playful of their groups. However, Leviathan for all her faults still fought to protect humanity, while Thetis despite his kind nature hates humanity and wants to wipe it out.
    • Siarnaq and Phantom are the black/purple-clad Ninjas of the group with shadow powers. They are both The Stoic and tend to be shrouded in mystery compared to the others. However, Phantom possessed Undying Loyalty to a cause greater than himself and died trying to fulfill it and his stoicness was just a natural part of his personality, while Siarnaq is a victim of being betrayed by those he once trusted and Left for Dead, resulting in him adopting a robotic mindset and personality so that he never trusts anyone else again.
  • Expy: The entire group is this to X's Four Guardians. Explains why they're the Biomatches for each Guardian's Legacy Character.
  • The Faceless: Siarnaq while Megamerged. All that you see of him behind that faceguard and helmet are two glowing red eyes.
  • Fiery Redhead: Atlas. Both figuratively and literally (well, mostly).
  • Fingerless Gloves: All of them.
  • Flechette Storm: Siarnaq; not as the boss, but as the copied A-Trans form. One press of the attack button throws four kunai knives; Button Mashing it results in... You get the idea.
  • Fuuma Shuriken: Siarnaq's Charge Attack in Grey's storyline.
  • Gender-Blender Name: It doesn't matter what you say, Mega Man ZX, Thetis is still a girl's name, and Atlas is still a guy's name.
  • Granola Guy: Thetis.
  • Ground Pound: Atlas; in Grey's storyline, it results in a stream of fire, while in Ashe's storyline, it results in a fire bomb that acts as a mine. She also transforms this way.
  • Graceful Loser: Although she takes a moment to tell Ashe she's a fool for not killing her and Grey that he'd wish he died ignorant of his past, Atlas is the only one of the four that both willingly concedes her defeat and seems to respect them for their strength, which fits with her mindset.
  • Hand Cannons Akimbo: Atlas, via her Knuckle Busters Sodom and Gomorrah.
  • High-Altitude Battle: Aeolus's stage, a forest lifted up because of gravitational anomaly.
  • An Ice Person: Thetis.
  • Idiot Hair: Thetis.
  • I Need You Stronger: When Grey/Ashe meets Aeolus and Siarnaq in the Tower Of Verdure, Aeolus tells him/her to hone their skills before they can effectively fight, and then he and Siarnaq teleport out. It later bites him in the ass, resulting in This Cannot Be! below.
  • Just a Kid: How Atlas views Thetis and Grey/Ashe. Thetis doesn't exactly take well to this and points out that she isn't that much older than him, and she seems to develop a small amount of respect for Grey/Ashe once they beat her.
  • Knight Templar: Atlas, Thetis, and Aeolus are this. Siarnaq is more unclear, since it's unknown what his motive for fighting is.
    • Atlas wants to force humans and reploids to grow stronger. Believing Misery Builds Character, her solution is to start a Forever War that will weed out weakness and leave only strong survivors.
    • Thetis wants to protect the environment, particularly the ocean, from pollution. Believing humans and reploids can't live on the planet without descreating it, his solution is to wipe them out entirely.
    • Aeolus wants to put a permanent end to the constant wars that have plagued the planet. Believing all conflicts can be tied back to the ignorant and foolish who refuse to understand, he intends to ensure only the enlightened and intelligent are left to rule the planet by killing those who don't meet said standard.
  • Know When To Fold Them: Siarnaq retreats from his battle with Grey/Ashe once he's defeated, stating that in his critical condition it would be hazardous to keep going.
  • The Lad-ette: Atlas.
  • Laughing Mad: Siarnaq. And how! It's dialed back into a Evil Laugh in English.
  • Left for Dead: Siarnaq was backstabbed by his pals and left to rot. It's the reason behind his extreme stoicism, lack of trust, and dislike of all relationships in general.
  • Limp and Livid: Siarnaq as Mega Man Model P.
  • Meaningful Name: With the exception of Siarnaq (who is named after a giant from Inuit Mythology), all of their names are the names of Greek Deities that correspond to the element they use. Atlas is commonly depicted holding up the globe and thus controls earth and fire. Thetis is a sea goddess and mother of Achilles. Aeolus is the god of the winds.
  • Megaton Punch/Punched Across the Room: Atlas has an appropriately-named "Megaton Crush," the half-Charged Attack of her Hand Cannon which can send enemies flying forward, possibly hitting another enemy on the way for an extra kill count, hence the name Knuckle Busters.
  • Misery Builds Character: Atlas' ethos is basically "Hard times create strong men" to an extreme degree.
    Atlas: It is through struggle that humans learn discipline and grow! I will be Mega Man King, for the war that never ends!
  • Ninja: Siarnaq.
  • Not Themselves: It's implied that the Biometals stolen from Vent and Aile have somehow been bent to the will of their Biomatches. Given that all four Biometals are inexplicably The Voiceless in ZX Advent, it's truly unknown at this point. Additionally, this is taken to a literal degree, as the Megamerges look different from their ZX versions (especially in the case of Siarnaq and Model P), most likely due to the absence of Model X. Gameplay-wise, they function the same, with the moveset of each Biometal usually split between Grey and Ashe.
    • It's also implied that the enemy Mega Men themselves are either being influenced or are outright brainwashed due to their red eyes, which, as seen in the case of Serpent and (briefly) Giro in the first game, may imply that Model W has some sort of hold over them.
  • Nothing Is Scarier: Siarnaq doesn't seem to have any motive at all for participating in the Game of Destiny. It only makes his robotic disposition and shadow powers even creepier.
  • Peek-a-Bangs: Aeolus.
  • Platform Battle: Thetis's boss battle. You're restricted to 3 small rock platforms over a Bottomless Pit. Using Chronoforce form may ease things a bit, though, since said form can swim.
  • Playing with Fire: Atlas.
  • Power Gives You Wings: Aeolus, technically, since he acquires Model H.
  • Pride: Aeolus, and how. Almost every other line out of his mouth is about how superior he is to other people and putting them down.
  • Primal Stance: Siarnaq's stance when in his Biometal form.
  • Professional Killer: According to his data disk, Siarnaq was an assassin at some point in the past.
  • Quirky Miniboss Squad
  • Red Eyes, Take Warning: Every single one of them. It makes their Team Shot with Master Thomas look all the more sinister.
  • Reverse Shrapnel: Siarnaq's Charge Attack in Ashe's storyline.
  • Scarf Of Asskicking: Siarnaq. Bonus points for being frayed at the edges to give him a more menacing look.
  • Secret A.I. Moves: Zigzagged. Model-A's copied version of their biometal forms lack any of their Desperation Attacks, as well as the occasional other move (such as Siarnaq's Flash Step and Thetis' ice spear projectile.) However, depending on whether the player is using Grey or Ashe, each boss will be using the exact charge attack that the player character will learn (i.e. Thetis summoning ice dragons when fighting Grey, or creating ice shrapnel when fighting Ashe.)
  • Shifting Sand Land: Atlas' stage, with additional crude oil mine and Raiders' crashed airship.
  • Shock and Awe: Again, Aeolus.
  • Smug Snake: Aeolus, all the way.
  • The Social Darwinist: Aeolus and Atlas, albeit in different ways. Aeolus believes only the intelligent deserve to live, while Atlas believes anyone strong enough to survive battle deserves it.
  • The Stoic: Aeolus and Siarnaq. The latter is notable in that he's refined it into Robo Speak.
  • Sword Beam: Aeolus fires them in a style like Harpuia, but he (fortunately) cannot spam them.
  • Talking to Himself: In English, Siarnaq is voiced by Jamie West, who also voices Model Z.
  • Teleport Spam: Siarnaq will constantly vanish and reappear during his boss fight. He noticeably leaves behind fading afterimages of himself as he does it, implying that he's using a variation of Model P's Shadow Dash ability.
  • Theme Naming: Like Prometheus and Pandora, Aeolus (Helios), Atlas, Thetis (Tethys), and Siarnaq were all supposed to be named after Saturnian moons. note  Additionally, Aeolus, Helios, Atlas, Thetis, and Tethys are figures from Greek mythology (a majority of them being Titans) whose powers and backstories correlate to the Elemental Powers of the quartet. In this regard, Siarnaq is the odd man out; his only mythological counterpart is a mythical Inuit mermaid patron of seals.
  • This Cannot Be!: The insufferably arrogant Aeolus cannot believe that he was bested by an inferior Mega Man like Grey or Ashe, calling them Detective and plebeian respectively. He leaves the fight claiming that he'll never acknowledge them and succeed in his goals.
  • Tomboyish Name: Atlas. Inverted with Thetis.
  • Underwater Boss Battle: Thetis, of course.
  • Villain Forgot to Level Grind: Presumably. They certainly didn't expect Grey/Ashe (relative newcomers to The Game of Destiny) to become more adept at using Model A in such a short time, to say the very least.
    • At least they were savvy enough to gang up on Grey/Ashe in the last level right before the Final Boss. Unfortunately, that's when Aile/Vent shows up to hold them off.
  • Well-Intentioned Extremist: Thetis and Atlas, especially Thetis. Atlas, as said above, wants humanity to become stronger, while Thetis wants to protect his beloved ocean from the progress of man. However, Atlas believes that humans can only evolve via suffering, and the ocean's safeguarding is very Serious Business to Thetis. Given that they're using Model W to accomplish said goals, their once-noble goals are taken to extremes.
  • Who Wants to Live Forever?: It is strongly implied that the four Mega Men's survival had to do with their having the Reploid Immortality data in the Hard mode Stinger, though Thomas' line about human bodies might imply that if any of the enemy Mega Men were humans, they'd be using a Body Backup Drive like Master Albert did.
  • Villain Respect: Aeolus, of all people, develops a bit for Model Z, stating that he has "beautiful resolve" to throw away his life to let Aile/Vent rescue Grey/Ashe.
  • You Don't Look Like You: In an odd way: Their Megamerged forms, being from a single Biometal (instead of a merge with Model X from the first game), doesn't match the forms of the Guardians themselves, except for Atlas' note  (although the same can be said for Girouette's form of Model Z). Some have theorized that it's because of the darker nature of the Enemy Mega Men's personalities, while some others theorized that the design evolved from their clothes note .
  • You Fool!: Aeolus is quite fond of this phrase.
  • You Gotta Have Blue Hair: Thetis with blue hair, Aeolus with bright green, and Siarnaq with dark purple.
  • Zettai Ryouiki: Thetis, a rare male example. Grade A/B.

ZX Pseudoroids

The main 8 bosses for the first game; each of them houses half of the Biometals you can acquire (in this case, the 4 Guardian Biometals).

    All of Them 

  • Alphabetical Theme Naming: Their names start with the letter of the Biometal they hold.
  • Animal Motifs: All of them have one, just like the countless Maverick bosses that preceded them.
  • Attack Its Weak Point: Attacking their weak point will deal more damage to them. The catch: it houses their respective Biometals, and attacking those points will damage the Biometals, making them having less weapon energy bar. Thus, the game grades you based on how much you hit it — the less, the better, and thus the trope is actually inverted if you're going for a good-conditioned Biometal. In fact, in the Zero/ZX Legacy Collection, the aptly titled "Laser Surgery" achievement is obtained after successfully getting a Lvl. 4 Victory (as in never hitting the weak point once).
  • Back from the Dead: All of them return for the Boss Rush in Slither Inc. despite losing their Biometal fragments. It's implied that Serpent used Model W's power to revive them, judging from how several claim they will "become one" with it upon their defeat. It's also mentioned in early conversations with the Guardians that the Pseudoroids possess natural regenerative powers as a result of Slither Inc. experimentation, which is why Vent/Aile can encounter them again after defeating four other Pseudoroids first.
  • Degraded Boss: A variant — Mook versions of each Pseudoroid appear in the sequel, with their Secret Disk entries revealing they possess the Pseudoroid DNA of the fallen bosses.
  • Dub Name Change: Similar to the way "Irregular" was changed to "Maverick", "Falseroid" became "Pseudoroid" over the translation.
  • Elemental Rock–Paper–Scissors: A mechanic carried over from the Zero series. Fire Pseudoroids are weak to Thunder, Thunder to Ice, and Ice to Fire.
  • Fire, Ice, Lightning:
  • Meaningful Name: As detailed in ZX Advent, Reploids were rebuilt between Zero and ZX to be more similar to humans design-wise to lessen the differences between the two. These ones were intentionally designed with more monstrous, combat-oriented bodies also designed to contain Biometal fragments; thus a "pseudo-Reploid". Their original name, Falseroid, applies for the same reasons.
  • My Death Is Only The Beginning: After their rematch fights their souls are absorbed into Model W, bringing the Biometal closer to completion.

    Hivolt the Raptoroid
Voiced by: Kousuke Ito
One of the Model H Pseudoroids, who guards Area E - Power Plant. He has nothing but contempt for Vent/Aile and spends most of his time condescending at them, but his strength backs up his arrogance.

    Lurerre the Abysroid
Voiced by: Kiyomi Asai
One of the Model L Pseudoroids, who guards the research station in Area F - Lake. Extremely vain and cruel, she supports Serpent like a deranged fangirl and has no time for anything that stands in his way.

    Fistleo the Predatoroid
Voiced by: Takashi Matsuyama
One of the Model F Pseudoroids, who guards the residential district in Area G he and his Mavericks attacked. Living only for fighting, he's driven solely by growing stronger and putting himself to the test.

  • Always Accurate Attack: One of Fistleo's attacks has him conjuring grey orbs that instantly appear in your position. The first one only appears in front of him, though, so you'll have a time to react.
  • Artistic License – Martial Arts: Uses his own blend of kenpō named "Reioh-ken" (literally meaning "Soul Center Fist").
  • Blood Knight: The entire reason he attacked Area G was to draw out someone who he could fight to the death with. He got his wish.
  • Dash Attack: He's got a couple, and his EX Skill is one; he cloaks himself in flames and blasts across the middle of the screen, fireballs trailing above and below him.
  • Drunk with Power: He followed Serpent to become stronger and hone his own skills, and being killed and resurrected doesn't change him at all. In fact, he's almost ecstatic as he's absorbed into Model W at the end of his rematch, only able to marvel at the "power of a god."
  • Expy: Fistleo can be considered one to Magma Dragoon in terms of his motives (trying to get more power and fight a worthy fight) and fire powers. His appearance, attacks, personality, and poses has some fans compare him with Akuma.
  • Graceful Loser: He's happy to be defeated in his rematch, as the power he feels as he's drawn into Model W is what he was searching for.
  • Heal Thyself: He can heal himself in-between attacks, though he can't move while doing so.
  • Kiai: Shouts battlecries as he uses his more powerful attacks.
  • King of Beasts: He's inspired by a lion.
  • Megaton Punch: One of Fistleo's moves is a massive lunging haymaker that, when connecting with the wall, will cause a shockwave.
  • Playing with Fire: He can create fireballs and leave a trail of flames behind him.
  • Removing the Head or Destroying the Brain: His Biometal fragment is contained in his head.
  • Shoryuken: Has one that he can use to bring fiery debris down on you from the ceiling.
  • Small Role, Big Impact: In Aile's storyline, he's the first to reveal that the "Maverick raids" deliberately left survivors who would have the potential to become Model W's vessel before any of the main villains or even Advent fully confirmed this.
  • Super Strength: He can punch clean through two large pillars of rubble with one strike.
  • This Cannot Be!: Upon being defeated the first time, he expresses disbelief that despite possessing the "power of a god" he was beaten by a little boy/girl.
  • Was Once a Man: It's all but explicitly stated that like Purprill, he was once an ordinary Maverick who got upgraded into a Pseudoroid.

    Purprill the Mandroid
Voiced by: Wataru Takagi
One of the Model P Pseudoroids, who guards the abandoned amusement park he invaded in the past. Specifically, he was a Maverick who took part in the raid that orphaned Vent/Aile, and was rewarded by being upgraded into a Pseudoroid.

  • An Arm and a Leg: His Biometal fragment is contained in his arms.
  • Arch-Enemy: Aside from Serpent, Vent/Aile made him theirs because of the role he played in their mother's death.
  • Ax-Crazy: Purprill is quite a hyperactive maniac.
  • Drunk with Power: Even Model P is disgusted with how carelessly he flaunted his own power.
  • Elite Mook: Was formerly a generic Maverick, until Serpent uplifted him into his current body.
  • Expy: Seems to be one to Clown Man. Both are childish and silly robots fought in an Amusement Park of Doom, use Extendable Arms to attack from a bar in the ceiling and can also compact themselves in a circular shape to spin around.
  • Extendable Arms: His hands can detach on cables to lift himself to the ceiling.
  • Face Death with Dignity: After his rematch, he rather nonchalantly states it was nice to be back for even a little while before willingly giving up his soul to Model W.
  • A Handful for an Eye: Purprill can attack by throwing the sand in his arena.
  • Killer Gorilla: His loose design basis, or some variety of mandrill or monkey as he has a tail.
  • Laughing Mad: Giggles and laughs throughout his fight, and cackles like a lunatic during his final attack.
  • Mad Bomber: Uses a number of explosives, some of which bounce around the ground.
  • Non-Elemental: Just like Model P, Purprill has no elemental ability. He can, however, still mimic Model P's ability by turning into a giant shuriken.
  • Punny Name: His name is Purprill, and he's a purple mandrill.
  • Small Name, Big Ego: He's one of Serpent's elite Pseudoroids, but he's cocky and quick to boast that Vent/Aile has no hope of defeating him since he's an "executive officer".
  • Spin Attack: His EX Skill. He curls himself into a giant shuriken, energy blades extending from his wrists and elbows, and bounces around the room like a ricocheting buzzsaw.
  • Stock Animal Behavior: Climbing and hanging from the ceiling.
  • Verbal Tic: Tends to intersperse his dialogue with "ook".

    Hurricaune the Wolveroid
Voiced by: Hisayo Yanai
One of the Model H Pseudoroids, who guards the prison in Area I - Confinement. Spiteful and sadistic, she intends to torture the people captured there until Vent/Aile show up to free them.

  • Attack Its Weak Point: Her Biometal fragment is contained within her neck.
  • Blow You Away: Whereas Hivolt focuses more on the lightning aspects of Model H's powerset, she focuses more on the wind portion, creating powerful tornadoes.
  • Everything's Better with Spinning: All of her attacks. One specific move has Hurricaune spin her whole lower body like a helicopter to descend on your head.
    • Ground Pound: The end of this move sends out 2 electric sparks as she touches the ground from the blade that serves as her tail.
  • Dying Curse: Proclaims that she'll never stop trying to kill Vent/Aile even as she's absorbed into Model W after her rematch.
  • In a Single Bound: She can leap up and off the screen easily during the fight.
  • Laser Blade: Projects them from her hands, neck, and feet to serve as propeller blades for her attacks. Her tail is another blade in itself, adding to her mythological inspiration.
  • Lightning Reveal: Once you reach her boss room, you walk to the door on the other side before lightning flashes multiple times, finally revealing her on the opposite side.
  • Razor Wind: Many of her attacks. One that she fires from the propeller blades around her neck travels forward and splits in half to climb the wall in front of her.
  • Sadist: Seems all too happy to torture the people interned in Area I. Which makes sense, considering what the ultimate intent behind it was.
  • Shock and Awe: Not as much as Hivolt, but one of her attacks causes damaging sparks of electricity to dance along the ground and ceiling when she lands.
  • Tornado Move: Loves these. One of hers is her EX Skill; Hurricaune jumps to the centre of the room and whips up a huge cyclone that drags Vent/Aile into it, firing Razor Wind up and down the vortex. The cyclone is actually quite similar to Model H's charged tornado move.
  • Wicked Weasel: Specifically, between her design and her wind motif she seems to be based on the Kamaitachi, a Japanese youkai.

    Leganchor the Gelroid
Voiced by: Osamu Tatsuya
One of the Model L Pseudoroids, who guards Area J - Underwater City and the research data contained there. He acts like an angry, senile old man, berating Vent/Aile for being youths who cannot comprehend the world.

    Flammole the Moleroid
Voiced by: Kouhei Fukuhara
One of the Model F Pseudoroids, who heads the volcanic mining operation in Area K - Lava site. He's fiercely loyal to his job, intending to keep digging until the Biometal signature he detects is unearthed.

  • An Arm and a Leg: His Biometal fragment is contained in his arms. Not hitting them is difficult, since they take up roughly 2/3 of his entire body.
  • Arm Cannon: Flammole's arms, which can fire contact-expanding fireballs, jets of flame, and double as tunnelling drills.
  • Dishing Out Dirt: Digs through the ground and sends boulders flying up from his burrowing.
  • Foreshadowing: When Flammole is killed, he remarked that the Biometal signal that he received was not what he thought it would be. Word of God (i.e Inti Creates staff) confirmed that it's meant to be a "giveaway". And note that, in the map, Area K (where Flammole is fought) is directly above Area N (where Model O is found).
  • Magma Man: A few of his moves, including his EX Skill, where he sends geysers of lava up from beneath you with a series of heavy Ground Punches, highly reminiscent of Fefnir and Model F's own. The third punch sends two up in front and behind you, and can only be avoided by standing still.
  • Mole Miner: Of course.
  • Pile Bunker: Seems to have one in each arm, and during his EX Skill you can see them deploy from his elbows.
  • Pint-Sized Powerhouse: The smallest of the eight Pseudoroids - barely shorter than you, even - and no less powerful for it.
  • Playing with Fire: He can launch fire waves in a flamethrower motion out of his arms.

    Protectos the Goreroid
Voiced by: Keikō Sakai
One of the Model P Pseudoroids, who guards Area L - Research Lab. Proud of his defensive power and size, his body contains a remaining data log from the original Guardians research team.

  • Arm Cannon: His hands can fire drill-shaped homing missiles or bombs.
  • Attack Its Weak Point: His Biometal fragment is contained in his belly.
  • Big, Bulky Bomb: His rhino horn (the larger one) is actually a devastating warhead that he fires as his EX Skill. The only way to avoid it is to huddle behind Protectos himself.
  • Deflector Shields: Protectos can conjure one, courtesy of the Model P stored in him.
  • Ground Pound: Protectos' arena has two platforms to jump up and down from, plus the ground. At the end of his movement cycle, he'll go up or down one to catch up with the player. But if they're beneath him when he's on the top platform, he'll drop down to try and crush them with his gigaton body.
  • Human Hard Drive: Protectos serves this role, like Zero 1's Ganeshariff.
  • Large and in Charge: Seems to be considered the military leader in charge of Area L's war zone backdrop, and he's the largest and heaviest of all the Pseudoroids.
  • Mighty Glacier: Protectos moves very slowly, but his ample firepower is nothing to laugh at.
  • Non-Elemental: Similar to fellow Model P Pseudoroid Purprill, Protectos doesn't get any elemental ability. He can still use Model P's power via creating a Deflector Shield in the same fashion as one of Model P's charged abilities..
  • Rhino Rampage: Definitely, though he doesn't do any charges.
  • Stuff Blowing Up: Protectos throws out a lot of explosives in his fight. He fires three varieties of bombs: two with vertical and horizontal blasts, and a third one with a delayed explosion.
  • Turtle Power: When he fires his horn warhead his arms retract into his shoulders, his legs lock into his sides, and his head withdraws into his torso. Apparently his ordinance can hurt even himself.
  • Undying Loyalty: Serves Serpent faithfully and promises to crush any opposition beneath his feet.

ZXA Pseudoroids

The main 8 bosses for the second game; they house fragments of Model W, unlike in the first game.

    All of Them

  • Animal Motifs: Like their predecessors and Mavericks before them.
  • Attack Its Weak Point: Unlike the first game, you can freely attack them, as there'll be no penalty for doing it. Not all of them have a weak point, however.
  • Back from the Dead: Albert reveals their souls are bound to Model W and thus he can revive them at will, doing so for the Boss Rush within Ouroboros.
  • Crippling Overspecialization: All of them as A-Trans forms; they have their uses, but once you have the Mega Man forms you probably won't be using them unless you have to.
  • Do Not Run with a Gun: Many of their copied forms prohibited you from shooting while running.
  • Dub Name Change: 6 of the 8 were named differently in Japan.
  • Fire, Ice, Lightning: With the Elemental Rock–Paper–Scissors from the previous game returning as well.
  • Not Completely Useless/Crippling Overspecialization: You either use them when you're just having fun or when you need to solve puzzles. The Mega Man forms are much faster than any of them, that's why.
    • Except Buckfire, whose speed and higher jumps makes him a comfortable method of getting from Point A to Point B when you didn't unlock enough beacons. The fact that you can spam his three-directional shots that ALSO do Damage Over Time to virtually all enemies and bosses in the game also makes him a good choice for some boss battles, most notably Queenbee. His only real weakness is his gigantic hitbox.
    • Vultron is similar, due to the fact that his glide can blitz past a lot of obstacles when used right and he can stick to walls indefinitely. His only real weakness is large hitbox and the lack of a projectile (though he does get an omni-directional short-range sound attack).
    • Argoyle & Ugoyle also are fine forms to use when transversing the environment, as their regular attack is a spammable bomb move. They don't quite have the mobility that the Mega Man forms do, but they're certainly servicable as forms to use.
    • In water, it's largely up to the player whether to use Model L or Chronoforce. Despite his bulky frame, Chronoforce's projectile attack covers a large distance and does impressive damage, any attack performed above him does not damage him at all, period, and he's faster on the horizontal plane than Model L. The only times you're required to use Model L are in non-combat areas were he needs to fit into corridors that Chronoforce simply can't, and after getting Model L, the only major water section of the game left is in the penultimate level, which largely plays to Chronoforce's strengths. That's not to say Model L is inferior, but Chronoforce definitely has it better than some of his allies. Additionally, he's a godsend in the final boss fight, where his immunity to attacks above him trivializes Albert's most difficult to avoid attack, and his Time Bomb does a good job giving you breathing room. However, using Time Bomb on hard mode will prompt Albert to hit back with his own.
  • Secret A.I. Moves: Hoo boy. You can bet at least one of their moves to be unusable as their copied forms, but major points go to Queenbee: The copied form of her lacks her signature beehive armory.
  • Self-Imposed Challenge: Beat them in certain ways and you can acquire medals, three for each Pseudoroid for a total of 24 medals.

    Buckfire the Gaxelleroid (Dearburn the Gazeroid)
Voiced by: Kenji Nomura (JP), Charles Glover (EN)
One of the Pseudoroids that attacks the train delivering Model A to Legion HQ. Unlike Prometheus and Pandora, he's not very impressed by Grey/Ashe becoming a Mega Man and tries to take Model A back by force.

  • Attack Its Weak Point: His mane at the back of his head.
  • Arm Cannon: Buckfire has two of 'em.
  • Bambification: Averted; he's an angry brute in the same vein as X2's Flame Stag.
  • Boomerang Comeback: His charge attack lets him use the blades around his arms as these.
  • Braids, Beads and Buckskins: Has a Native American motif.
  • Dash Attack: Has one (see Horn Attack below). It doesn't go that much faster than his normal run speed.
  • Disc-One Nuke: Buckfire is the first boss whose data is copied and is the Lightning Bruiser amongst the Pseudoroids, able to move as fast as Model A's dash regularly and packs a mean punch. He'll be the most useful form for all-purpose combat until Grey/Ashe copy their first Mega Man data, and will stay one of the best Pseudoroid forms for general battles for the whole game.
  • Diving Kick: Buckfire has a potent one that can break weak walls.
  • Dumb Muscle: His concerns are his job and the retrieval of Model A, and not much else. His Hulk Speak doesn't portray him as being much smarter.
  • Expy: Of Flame Stag from Mega Man X2.
  • Horn Attack: He can either dash with his horn pointed forward, or do a Shoryuken with his horn. The latter can break weak walls.
  • Hulk Speak: Buckfire speaks this way.
  • Knight Templar: Buckfire values order above all else. He gets pissed at Model A choosing a "Defective" like Grey as a Chosen One, and expresses confusion at the idea of a "girl" being a Mega Man if it's Ashe.
  • Locomotive Level/Traintop Battle: Buckfire's stage.
  • Marathon Boss: When gunning for the gold medal, by Mega Man standards anyway. Collecting it requires you to damage him by only throwing kunai at him with Model P using the touch screen. Each shot of this does one point of damage, and for dealing one point of damage a hit and having to wait for Mercy Invincibility to wind down after the fact, that's gonna take a while.
  • Playing with Fire: He unleashes flame arrows and his Diving Kick is tipped with a powerful jet of flame.
  • Rocket Jump: Buckfire's upwards horn attack can be used as this.
  • Secret A.I. Moves: One of the only aversions in the whole game. Everything he can do in his boss fight, you can do. The closest thing to this is your inability to go from his Rocket Jump into his Diving Kick.
  • Spread Shot: His arrows do this, firing three shots that fan out straight ahead.
  • Sprint Shoes: His default run speed when A-Transed into him is the same as most Megamerged forms' dash.

    Chronoforce the Xiphosuroid (Chronophos the Tridenroid)
Voiced By: Masakazu Kohara (JP), Iain Gibb (EN)
A fatalistic Pseudoroid stationed in the Arctic Ice Floe area. When Atlas decides to drop Grey/Ashe into the water, he's all too eager to try and take Model A back from such "unworthy" Chosen Ones.

  • An Ice Person: He fires ice arrows for his major offense.
  • Crippling Overspecialization: If he's out of the water, he's out of luck.
  • Die Laughing: Even as he dies, he takes solace in the fact Grey/Ashe are just pawns dancing about and belts out a laugh.
  • The Fatalist: Chronoforce has a lot to say about the inevitability of death and how everyone's time runs out, likely stemming from his own powers. Both times he's beaten, he just mocks Grey/Ashe about their inevitable failures.
  • Flunky Boss: Chronoforce can summon miniatures of himself from his shell which launch themselves at Grey/Ashe.
  • Luckily, My Shield Will Protect Me:
    • Chronoforce's top shell is impervious to spikes and most attacks. It makes two of the Final Boss' otherwise annoying-to-avoid attacks a trivial matter.
  • Seldom-Seen Species: He's a horseshoe crab.
  • Secret A.I. Moves: Creating mini-Chronoforces to launch at you, and his EX Skill where he swims to the background and fires a Macross Missile Massacre at you before rewinding time to hit you with it in reverse.
  • Spread Shot: Of the "explosive" variety. During his time stop attack, the icicles he fires from the background will split into four on contact. They will then re-materialize and reform when he rewinds time, making it harder to avoid them.
  • Spike Shooter: His primary method of attack is firing icicles from his body.
  • Time Master: Chronoforce proclaims himself as such. One of his attacks even include firing icicles that come in different directions, then reversing time to make the icicles fly back at him.
    • Bullet Time: Chronoforce's Charged Attack lets you slow down time. The effect persists even if you change forms. During his boss battle, if he uses it he and his own attacks get a jump-up in speed, including his Limit Break.
    • Very High Velocity Rounds: Your bullets will work as usual while the time slows down.
  • This Looks Like a Job for Aquaman: He has ice attacks, an invulnerable shell, and similar mobility to Model L in the water (with a much longer water dash), but outside of the water he's dead weight. Pressing any movement or attack button just makes him grunt with effort and twitch slightly.
    • Lethal Joke Character: That said, while he can't move at all on land, he is immune to attacks from attacks from above and its charge shot, the Time Bomb, is very useful. You can even change form after it's activated.

    Rospark the Floroid (Rosepark the Floweroid)
Voiced By: Kunihiko Yasui (JP) Tom Clark (EN)
A campy Pseudoroid who guards the Tower of Verdure, sacrificing unfortunate intruders to the Model W within.

  • Ambiguously Gay: Rospark may be a robot, but he sure acts the part. A rose-based Pseudoroid with a clownish voice who enjoys fighting Grey while acting like Ashe is full of cooties, wields electrified vine whips as a weapon, has a large, pink very phallic rod at his groin area (it, and the one on his head, are parts of a lightning cannon), and have we already said that he is a rose? Is there any other way to take that?
  • Crippling Over Specialization: Unlike Chronoforce, whose uselessness on land is undercut by the handful of useful powers he can use in a pinch, Rospark as an A-Trans form is functionally useless in his bulb form. His jump barely gets him a foot off the ground, unable to even vault over small ledges, and his movement speed is slower than even Bifrost. His attacks being limited to a close-range whip and a strictly-vertical bullet attack puts him at an even bigger disadvantage. And his flower form, while more versatile in attack options, is limited to only being used in areas with climbable ropes (and Queenbee, Vulturon, and Model H can make such platforming redundant in all but the longest such sections where they have no safe place to land and/or regain weapon energy for flight).
  • Heal Thyself: He recovers some of his health during his final attack.
  • Mirror Match: The subject of his Gold Medal, which requires you to knock him out while only dealing damage while transformed into him. Considering which one of you takes damage if you bump into each other, that's a bit of a tall order since he can hog the wires all he wants. It's important to remember that the condition says you can only damage him while transformed into him, not that you're not allowed to use any other transformations at all, so you can level the playing field significantly by dropping Chronoforce's Time Bomb. Also don't forget that the thrown projectile attack while on a vine deals more damage than the head projectile while in Bulb form or vine slapping in either form.
  • Plant Person/Something About a Rose: He is both.
  • Secret A.I. Moves: In his flower form, the electrical beam attack he fires across the screen.
  • Shock and Awe: He can charge his vine whips and thorns with electricity that not only increase their damage, but can increase his attack range by electrifying the vine he touches with the former and creating a field between where the three charged thorns land. His EX Skill is him unleashing an electricity-based Wave-Motion Tuning Fork.
  • Sitcom Archnemesis: He starts developing this towards Ashe in her story, first being annoyed about how she distracts him from killing the Raider Gary before getting angry at listening to her talk, then expressing disbelief at being killed, to not at all being thrilled to see her again on Ouroboros and having to fight her again, to finally loudly expressing his desire to never see her again as he's defeated for the final time.
  • Spike Shooter: He can shoot rose thorns in either form.
  • Spread Shot: Rospark's thorns are of the Spray Bursts variety in flower form. When charged, they create an electrical field between the points of impact and damage anything within it.
  • Stance System: Rospark has 2 forms: bulb form and flower form, the latter accessible by climbing ropes. He spends the majority of the boss fight in flower form and only turns to bulb form when he drops off the vines for either the occasional attack or Grey/Ashe managed to nail him with a ice attack that hit-stuns him off.
  • Wave-Motion Tuning Fork: As a boss, Rospark for his EX Skill can use the rods on his head and crotch to fire off an electric laser.
  • Whip It Good: Rospark can weaponize his thorny vines like this. He can even electrify it.

    Vulturon the Condoroid (Condorock the Vulturoid)
Voiced By: Kissho Taniyama (JP), Iain Gibb (EN)
A guitar-wielding Pseudoroid fought at the Scrapyard, who boasts of using his power to reanimate fallen Mavericks and awaken the Model W fragment within he's guarding.

  • Close-Range Combatant: Aside from the hazards deployed from his arena, his moves are pretty much limited to a short-range sonic wave and using his guitar as a club. This carries over to his A-Trans form.
  • Expy: Zombielike? Check. Uses a guitar? Check. Has a crazy rocker personality? Check. He must've been taking some notes from Lord Raptor.
  • Feathered Fiend: Based on either a vulture or a condor, depending on which part of his name you want to run with.
  • The Fighting Narcissist: Vulturon always wants his fights to be "rocking".
  • Flight: Vultron has a glide that he can only use to go from side to side (though his wall-climbing ability can help compensate with proper position before use), but it has fast movement and will last as long as he has weapon energy to spare.
  • Flunky Boss: Frequently summons literal trash mooks called Funky Junk that you saw in the stage, as well as amp-like objects from the ceiling that have no database entry and therefore no particular name.
  • Graceful Loser: Vulturon shows shades of this after his rematch, telling Grey/Ashe he's "gonna retire" and for them to "carry on with the show and give 'em a Mega performance".
  • Instrumental Weapon: His guitar can project barriers, raise dead machines, and control the machinery and traps in the background of his stage.
  • Interface Screw: Being too close to his arena's speakers can cause the player to temporarily have their left/right controls inverted or their weapons disabled, similar to the radar dishes from Area-L in the first game.
  • Marathon Boss / Goddamned Boss: When chasing the Gold Medal, anyway. Vulturon's Gold Medal requires you to knock him out using nothing but the Giga Crush. Thankfully, considering his tendencies, this only counts for him personally, so you can destroy the various things he summons any way you find convenient. Not so thankfully, the Giga Crush can only be used while your Biometal energy is full, doesn't do a whole lot of damage for the time it takes said energy to recharge, and poor timing can result in things dragging out even longer as a result of how frequently Vulturon turns invincible and teleports, let alone if he just wanders too far off screen. What can cause things to drag out significantly longer is if you've picked up capacity upgrades for your Biometal energy, as the Giga Crush will still chew up the entire gauge, still cannot be used unless it's full, and still recharges at the same pokey pace it always has, with no adjustments for its increased length. Woe unto you if you've collected all four of them, as then you'll be in for the long, long haul. Oh, and remember that W Tank from ZX? Yeah, that's gone, and the things he summons will never drop items, so you'll get no graces on that point.
  • Metal Head: Vulturon, fitting his theme, likes head-banging. It also helps that he's voiced by Kishō Taniyama.
  • Musical Assassin: Vulturon fights with a guitar-shaped instrument and 2 amplifiers. With those things he can animate pieces of junk, create a barrier of sound force, screw with your movement or just smack you with it.
  • Necromancer: Of a mechanical variety. His guitar playing can reanimate zombie Mavericks. Crosses over with Flunky Boss.
  • Non-Elemental: Though technically it would be sound.
  • Razor Wind: Not quite, but the sound wave he fires to raise his zombies looks looks like one, and hurts you if it touches you.
  • Rockers Smash Guitars: At close range or as an A-Trans form, he can use his guitar as a melee weapon. It can smash weak blocks.
  • Secret A.I. Moves: Basically everything he can do with his stage, from bringing down skull-shaped chandeliers to firing junk from his speakers like a cannon, and of course his zombie Mavericks.
  • Wall Crawl: Not exactly. While most A-Trans/Megamerge forms can Wall Jump and slide down walls to slow their descent, Vulturon can cling to them indefinitely. This enables him to move weights that would otherwise block your progress.

    Queenbee the Hymenopteroid (Kaisemine the Wasproid)
Voiced By: Mari Adachi (JP), Vicki Glass (EN)
A Pseudoroid guarding the Control Centre, which is overloading the thermal furnaces of the neighbouring cities and will cause an explosion, while also guarding a Model W fragment contained there.

  • Attack the Tail: Queenbee's weak point is her abdomen, which is typically protected by her beehive armory.
  • Ax-Crazy: She really craves for destruction and terror, expressing excitement at the destruction the runaway thermal explosion will cause and eager to witness the upcoming cataclysm caused by Ouroboros.
  • Bee Afraid: And how.
  • Bee Bee Gun: Deploys swarms of small bee drones from her beehive to hunt you down. Doubles as Flunky Boss.
  • Beware My Stinger Tail: Of course. She uses it mainly as a cannon rather than a stinger, though.
  • Bottomless Magazines: Not just her arsenal, but when her armory is destroyed she'll fly around for a bit firing from her stinger cannon before flying off and returning with a new one.
  • Expy Of Blast Hornet from Mega Man X3.
  • Flight: Queenbee has true flight and can move in any direction, though it costs weapon energy for each "bounce". Carrying something doesn't slow her down at all.
  • Frickin' Laser Beams: Queenbee as a boss can fire many lasers from her beehive (think of a disco ball). She can also fire a strong laser downward that causes burning rubble to pop outward.
  • Macross Missile Massacre: Queenbee as a boss can fire these out of her beehive.
  • Playing with Fire: She fires heat lasers and fireballs.
  • Plug 'n' Play Technology: Her abdomen can telescope on itself to allow Queenbee to dock herself into tanks and containers, allowing to carry them from one location to the next. This is presumably how she connects with her armory.
  • Secret A.I. Moves: The most egregious example. If you were hoping to use her beehive armory once you defeated her, prepare for disappointment.
  • Walking Armory: Queenbee enters her boss fight toting a huge beehive tank containing cannons, drones, and missile launchers. It can be destroyed to do huge damage to her. There's actually two achievements for defeating her by only destroying her beehive to damage her and never attacking her beehive respectively.
  • Verbal Tic: Tends to refer to things in terms of bees and flowers, i.e "the nectar of terror".

    Hedgeshock the Erinaceroid (Tesrat the Hedgeroid)
Voiced By: Kokoro Kikuchi (JP), Lynn Harris (EN)
A hyperactive, childish Pseudoroid that guards the final room of the Mysterious Lab under "Mr. Albert's" orders and is annoyed by those who don't take her seriously.

  • The Baby of the Bunch: Has this dynamic with the other Pseudoroids, being the smallest of the bunch and acting the most immature of them all.
  • Defiant to the End: After her rematch, she states "Mr. Albert" will still kill Grey/Ashe regardless of her loss.
  • Drowning Pit: You can't drown, but she'll flood her arena on occasion to limit your mobility.
  • Expy: Could be considered one to Sonic the Hedgehog and Pikachu.
  • Flunky Boss: Can occasionally call in a pair of mouse robots to distract or harm you.
  • Fragile Speedster: The smallest and quickest of the Pseudoroids, but not all that powerful with Model A even stating she's not very suited to taking on foes. Notably, one of her challenge missions requires you to fight her without using an A-Trans form, and she's the only boss this is asked of aside from the Warm-Up Boss. The other is to defeat her as Chronoforce when she floods her arena.
  • Hoist By Her Own Petard: The second of her achievements is to defeat her by punching one of her mouse robots into her.
  • Marathon Boss: Like Buckfire, claiming her Gold Medal requires you to knock her out using an attack that only does one point of damage, though this time it's the Buster in your untransformed state, meaning that getting around her will also be clunky at best.
  • Motor Mouth: Talk very quickly and tends to repeat her statements.
  • Prickly Porcupine: Hedgehog, but close enough.
  • Rolling Attack: Is very is fond of this. As an A-Trans form, it allows her to bust through regenerating gel in narrow passageways that would otherwise block Gray/Ashe from crawling through.
  • Shock and Awe: She can launch electric balls.
  • Spread Shot: Her charge shot, of the Initial Spread variety. It fires up or down depending on whether you're on the ground or in the air.

    Bifrost the Crocoroid
Voiced By: Banjo Ginga (JP), Jeff Manning (EN)
A massive Pseudoroid guarding the Bio Lab and the army of Mechaniloids created there. Incredibly loyal to the future Mega Man King, he slaughters all intruders without hesitation.

  • Advancing Wall of Doom: He can perform this himself by opening his jaws 180˚ and walking forward.
  • Attack the Tail: His weak point.
  • Bad Vibrations: Bifrost is so huge and heavy that every time he takes a step, it's accompanied by a large stomp and a small shake of the screen to emphasize it.
  • Breath Weapon: Has an icy breath that can freeze you solid, leaving you open to get stomped on. Doubles as a Secret AI Move.
  • Deadly Disc: Spits out a spiky razor disc from his mouth that climbs walls until it hits a ceiling.
  • Defiant to the End: Upon being defeated in the rematch, he only tells Grey/Ashe that being born in Albert's shadow means they "can never make a world of light."
  • Expy: Of Wheel Gator from Mega Man X2. Their primary weapon is even identical in form and function.
  • Goomba Stomp: Bifrost can do this to smaller enemies, which makes sense considering he's a giant metal crocodile and the largest Pseudoroid in the game.
  • An Ice Person: He launches his ice teeth for an attack and as a boss can launch an icy breath.
  • Luckily, My Shield Will Protect Me: Bifrost can defend himself by opening his large jaw. The player can, too, when they gain his A-Trans form.
  • Mighty Glacier: Oh, yeah. He has great attack power (probably the most impressive of the entire playable forms), but he moves very slowly. Bonus point of being An Ice Person, fulfilling every sense of the trope name.
  • Never Smile at a Crocodile: He is one.
  • Now That's Using Your Teeth!: Bifrost's large jaws and strong teeth leads to this. His bite can break through blocks that other forms can't even scratch.
  • Power-Up Letdown: His greatest weapon as a boss is your greatest weakness as a playable form: his size. Unlike the boss version, you don't deal Collision Damage to enemies and not only is he an enormous hitbox, he's actually too big to fit in most rooms.
  • Spike Shooter: As a boss or A-Trans form, he can fire his teeth as icicle missiles. They run off your weapon energy, though, so they can't be used infinitely.
  • Tail Slap: Bifrost can whack enemies with his tail as he switches direction. Again, justified by the fact he's a giant metal crocodile.

    Argoyle & Ugoyle the Shisaroids
Voiced By: Maki Mizuma [Argoyle] and Eriko Nakayama [Ugoyle] (JP), Terry Osada (EN)
Twin Pseudoroids protecting the Waterfall Ruins and the computer facility used to hack into Legion HQ.

  • An Arm and a Leg: Their weak points; Argoyle's is his hands and Ugoyle's is his legs.
  • Angry Guard Dog: They're based on the shisa, a mythological dog/cat hybrid symbolizing protection.
  • Combination Attack: Argoyle and Ugoyle are fond of these.
    • As the playable version, you can have Argoyle throw a bomb and then have Ugoyle's ghost kick it in order to power it up.
  • Doppelgänger Attack: You can only control Argoyle after you defeat the twins, but you can summon Ugoyle's ghost as a special move and the secondary attack.
  • Dual Boss: You fight them both at the same time. While it is possible to just focus on one at a time to cripple their moveset with the defeat of one, all three achievements for their fight can only be obtained if they're defeated at the same time in various ways.
  • Goddamned Boss: As far as all of their Medals are concerned, since they all require you to knock them both out simultaneously with various attacks. Not helping is that their health is shown in a single bar and while Model H gives a readout of what they've got left individually, it's not a terribly specific readout so there's still guesswork, on top of the fact that they both have weak points so a hit might do more damage than you intended.
  • Graceful Loser: After their rematch, they concede that you have beaten them and submit their loyalty before exploding.
  • Identical Twin ID Tag: Argoyle has larger ears, an open mouth, and a small jewel on his forehead. Ugoyle has shorter ears, a closed mouth, and a horn on his forehead.
  • Intangible Man: The summonable Ugoyle can pass through walls, the limit being whatever's in range of his sprite (which is always summoned right in front of Argoyle). This does allow Ugoyle to attack enemies hiding behind shields or walls with impunity in his range.
  • Kick Chick: Gender-inverted with Ugoyle, who's main offense is kicking targets and Argoyle's bombs, which makes them even stronger.
  • The Last of These Is Not Like the Others: Unlike every other Pseudoroid (and most Mega Man bosses in general, for that matter), the two of them are fought at the beginning of the stage and not the end. It's lampshaded that if they're guarding the entrance and not the final room, then whatever they're guarding has to be important.
  • Mad Bomber: Argoyle specializes in throwing bombs that are designed to bounce off obstacles once before exploding.
  • Non-Elemental: Though their Limit Break does have a bit of a darkness theme to it.
  • The Quiet One: When Ugoyle does talk, he's very blunt. According to a ZX series blog, his language setting is set on low to prioritize supporting Argoyle, who has a more developed language circuit to prioritize his giving directions.
  • Rollerblade Good: Argoyle and Ugoyle's feet are fitted with wheels. In fact, their A-Trans form has unlimited dash.
  • Secret A.I. Moves: Many of their moves, since they operate as a duo and you can only A-Trans into a solitary Shisaroid with the second as an extra attack option.
  • Shared Life Meter: Argoyle and Ugoyle, when fought, initially appear to have single health bar. However, when you activate Model H and use it to Enemy Scan them, you'll see that each of them has their own health bar.
  • Sibling Yin-Yang: Argoyle has an open mouth and talks a lot, while Ugoyle has a closed mouth and only talks in short words. They're also named after Buddhist figures Agyo and Ungyo.
  • Wonder Twin Powers: If one is defeated before the other, they lose the ability to use their Limit Break.


    In General 
The major Phlebotinum for this series, they exhibit the following tropes:

  • Empathic Weapon/Sentient Phlebotinum: Except for the bonus Biometals (Model O and a[ncient]).
  • Fun with Acronyms: They establish the M.E.G.A. (Meta-Encapsulated Granule Awareness)/R.O.C.K. (Rebirth Of Crystallized Knowledge) System; in layman's terms, this system enables the user to Megamerge/Rock On with it.
  • Legacy Character/Soul Jar: Except for Model A and Model a.
  • Only the Chosen May Wield:
    • Specifically, only those with Albert's DNA can successfully Megamerge with a Biometal.
    • The first leader of the Guardians (Ciel) states that in order to make Models X, Z, H, F, L, and P, she had to use the same data she acquired from studying Model W, meaning that anyone who can Megamerge with them has the same potential to use Model W and thus also has to meet the requirement of having Albert's DNA.

    Model X

I am the light that illuminates all possibilities, Lumine Infinitus...
Voiced by: Takahiro Mizushima (JP), Iain Gibb (ZXA, EN)

Based off the legendary hero X, he, along with Model Z, was escorted by Vent/Aile and Giro in the first game. It and Vent/Aile fell off a cliff when his/her motorbike gets shot by Mavericks. In a desperate attempt to defend Prairie and Guardians from the incoming Giga Aspis, Model X offers him/her the power to stop it, becoming his/her Biomatch in the process. When Vent/Aile gets injured after Serpent curbstomps him/her, Model X got weakened a bit, and cannot be used on his own; this triggered their first Double Megamerge with Model Z (courtesy of Giro dying and giving said model to Vent/Aile). He's still in Vent/Aile's possession as he/she appears in the second game.

  • Blue Is Heroic: Very blue, and as anyone with knowledge of past Mega Man series will know, very heroic.
  • Charged Attack: It wouldn't be X without his trademark Charge Shot.
  • Disc-One Nuke: The double charge shot can hit with both shots in rapid succession (Mercy Invincibility be damned, provided that you shoot the second shot immediately after the first), thus being able to inflict ridiculous amounts of punishment. But of course, you won't get long to enjoy it before Model ZX overwrites X's slot on the menu.
    • Promoted to Playable: Beating ZX with both characters adds Model X back to the menu for the entire game.
  • Guns Akimbo: It has X's double charged shot from Mega Man X2 and X3. May as well be two guns in one barrel.
  • Messianic Archetype: Even after all these centuries, some things just never change.
    Vent/Aile: You said your name was Model X. Why did you help me?
    Model X: Do I need a reason to help people? You seemed determined to help that girl even though you've never met her before. I just gave your bravery a little power to back it up.
  • Power Copying: His Double Megamerge feature assimilates the other Biometal's power for the Model X's user to use.
  • Red Baron: "The Blue Mega Man".

    Model Z

I am the courage that fights for beliefs, Fortitude Creed...
Voiced by: Yuuto Kazama (JP), Jamie West (ZXA, EN)

Based on the legendary hero Zero, Girouette is his Biomatch, either by the start of the first ZX (in Vent's storyline) or from when Aile was still young (in Aile's storyline). After Giro got mortally wounded, he gave Model Z to the hero. Like Model X, he's still in Vent/Aile's possession as he/she appears in the second game.

  • Boring, but Practical: Model ZX doesn't have all of the fancy bells and whistles of the other Biometals, having just sword slashes and energy shots as well as lacking an Overdrive, but ZX never runs out of weapon energy (due to lacking a meter to begin with), is strong in both melee and ranged combat, and has the least restrictive animations which increase dodging potential. Thus it is usually the most practical model for general combat.
  • Charged Attack: Both the ZX Buster and ZX Saber can be charged and unleash a powerful blast or strike.
  • Infinity -1 Sword: In Advent, the Model ZX form is obtained at around the 2/3rd mark of the game and is considered the best of the Mega Man forms in terms of versatility and practicality. While it's not necessarily the strongest form in terms of attack power, it's strong in both melee and ranged combat, the least restrictive animations with increased dodge potential, and while it now uses weapon energy said energy regenerates anyways and it gains special moves that weren't available in the first game. Consider how the Mega Man forms are generally superior to the Pseudoroid forms in terms of general exploration and combat, and Model ZX becomes very well the best form, period.
  • It Was a Gift/Memento MacGuffin: How Vent/Aile refers to him in the second game.
  • Laser Blade: Interestingly enough, the blade of Model Z as used by Giro alone more resembles a katana (and thereby Zero's Z-Saber from the X series), while Model ZX's as used by Vent/Aile resembles its design from the Zero series.
  • Never Found the Body: Well, he doesn't actually have a body to find, but it's made ambiguous whether or not Model Z actually dies when Ouroboros is destroyed. Vent/Aile don't mention it because Ashe/Grey don't bring it up and don't know about said sacrifice (only making a comment about "how there are still things that need finding"), and the four Mega Men he paralyzed show up alive and well in The Stinger. Model Z himself repeatedly states he's not dying there.
  • Power Makes Your Hair Grow: As Double Megamerge with Model X, Model Z somehow can provide this.
  • Red Baron: "The Red Mega Man" as Mega Man Model Z, though it becomes the much more fitting "The Ultimate Mega Man" as Model ZX.
  • Red Is Heroic: Very red, and anyone familiar with the previous two series will know he's very heroic.
  • Shoryuken + Sword Beam: A new technique for Vent in the second game.
  • Swiss Army Weapon: The ZX Saber switches between Saber and Buster modes in an instant.
  • Sword Plant: A new technique for Aile in the second game, which launches boulders into the air.
  • Sacrificial Lion: It's Zero, so this doesn't come as a tremendous surprise, but at the end of Advent, Model Z disengages from Vent/Aile to single handedly hold the Enemy Mega Men off, allowing the protagonists to escape while he goes down with Ouroboros. Though whether or not he actually dies is left ambiguous.

    Four Guardians Biometals
From clockwise: Model H, Model L, Model P, and Model F.
Based on Harpuia, Fefnir, Leviathan, and Phantom of Neo Arcadia's guardians. Unfortunately, just like their past selves, they have a bad habit of being used by the villainous camp (although this time unwillingly).

    Model A
Voiced by: Yuu Kobayashi (JP), Katie Adler (EN)

The most mysterious of the Biometals and a central figure of ZX Advent. He seems to be based on Axl, but given the lack of proper conclusion to the X series, who knows.

  • Awesome, but Impractical: The Giga Crush attacks everything on the screen and can wipe out most minor enemies instantly while doing pretty significant damage to bosses and minibosses, but it requires and drains the entire weapon energy gauge, even if Grey/Ashe collect the Weapon Energy extensions scattered around.
  • Bait-and-Switch: He is in fact, not Axl, but a copy of Master Albert's systems that just happens to be very similar to Axl. Or is he?
  • Bratty Half-Pint: Hard not to figure Model A as one of these, just listening to him yap.
  • Chain Lightning/Roboteching: Their Homing Shot; the former in Ashe's storyline and the latter in Grey's.
  • Charged Attack: Two of them. It has the standard charged buster shot for Grey and a Reflecting Laser for Ashe, and its Giga Crush also needs to be charged up before being used.
  • Cowardly Lion: Early on, Model A often expresses fear of getting into life-threatening situations and becomes exasperated by Grey/Ashe's intentions to rush in and help. He grows out of this as the story goes on.
  • Crossdressing Voices: Model A identifies itself as a "he", but is voiced by a woman in both Japanese and English.
  • Embarrassing First Name/Do Not Call Me "Paul":
    Albert: A backup system that contains my plan and my knowledge. Model A... In other words, Model Albert.
    Model A: I hate that name!
  • Gradual Regeneration: Its weapon energy slowly regenerates over time, unlike in previous series.
  • Guns Akimbo: Subverted. Grey and Ashe are shown doing this in their promo art when Megamerged, but in-game Model A gives no such ability. Except in their Giga Crush, that is.
  • Laser-Guided Amnesia: At the start of the series, he doesn't know who built him or what he's built for.
  • My Master, Right or Wrong: Surprisingly averted for a Biometal. Model A actually wants to flee the Train when the Mavericks attack it, despite Grey/Ashe's intentions to help the Hunters on it. That said, when they push the issue, Model A reluctantly goes along since he knows he's a sitting duck for the bad guys without them.
  • Neuro-Vault: In the form of ciphers that are unlocked whenever Model A copies another Mega Man's DNA. Unlocking each of them reveals the one behind the whole mess and his intentions.
  • Power Copying/Voluntary Shapeshifting: Its A-Trans ability works this way.
  • Reflecting Laser: Ashe's charged shot.
  • Red Baron: "The Copy Mega Man" for Model A, while it's "The Ancient Mega Man" for Model a.
  • Secret Keeper: After they collected the last cypher (from Vent/Aile), he remembers his purpose (that is, as a backup should Albert somehow fail), and considers it for the best that he doesn't tell Grey/Ashe about it until they're ready. Albert ends up doing it first, though.
  • Smart Bomb: Its Giga Crush attack lets the user shoot everything around them.

    Model W

The original Biometal, and the major driving force of the games. It was created at the end of Mega Man Zero 4, when Dr. Weil merged with Ragnarok and was destroyed, but with the fragments still containing his mind. It causes otherwise normal Mechaniloids to change into Mavericks and can corrupt people's minds. The Big Bads of both games seek to revive its powers. As it turns out, Master Albert supposedly "created" them all. It comes in two forms: a miniature version like the other Biometals which totally doesn't look like the man from from whom it originates, and the giant Model W Core of which there are tons.

  • All Your Powers Combined: Albert's Model W exhibits the powers of all of the Biometals.
  • Ambiguous Situation: The exact specifics of Model W's creation and influence are noticeably vague. While it's undeniable that Model W was made from Ragnarok's fragments and Albert had a major hand in refining them into their current form, exactly how much influence Albert had in their creation is unclear. There's also the question of how much influence Model W has actually had on the antagonists given its Sealed Evil in a Can state and the fact that it never actually speaks for itself.
  • Artifact of Doom: What else can be said of a device that creates Mavericks, feeds on negative emotions, grants incredible power at the cost of sanity, and houses the soul of one of the most evil beings in Mega Man history?
  • Back from the Dead: The souls of the ZXA Pseudoroids are bound to Model W, and thus, it can resurrect them via the "True A-Trans". It's implied that something similar happened to the ZX Pseudoroids after they were revived in Slither Inc. Fitting, given Dr. Weil's specialty in the MMZ series is DNA revival.
  • The Corruption: This biometal is the source of the many Maverick attacks taking place throughout the series. In addition, it's heavily implied to be the one influencing the actions of both Serpent and Albert, causing both to become delusional megalomaniacs in the process.
  • Emotion Eater: It eats negative emotions of the people to activate itself. The Model W Core in the first game fully activates when it feasts upon Vent/Aile's years of pent-up hatred for Serpent, while the fragments in Advent do so by feeding on the centuries of hatred Prometheus and Pandora have for Albert.
  • Evolving Weapon: Serpent's final form in ZX becomes bigger and more imposing with every life bar you knock off, and the last stage of this reveals a giant mechanical face, as if to suggest some person or presence is on the verge of awakening. (Three guesses as to who...)
  • Expy: Aside from the obvious, Model W's ability to feed on negative emotions is similar to Evil Energy and it's ability to feed on the evil within its host to multiply and spread.
  • Greater-Scope Villain: For the entire ZX series as the main source of Mavericks plaguing the world and the source of the villains' plans (and corruption).
  • Hate Plague: The thing causes hatred and other negative feelings to appear within people in vicinity.
  • Hijacked by Ganon: Seeing as it's Dr. Weil, the Big Bad of the previous series, and it's ultimately the driving force of both games so far.
  • Light Is Not Good: Mainly colored gold and white, and, in case of Albert, looking like a seraphic angel when he transforms. Unquestionably evil, given its origins.
  • Mechanical Abomination: The core. Even if it is an immobile twisted-up chunk of metal, it looks as if it wants to gnaw your face off. The other cores in Advent don't all look quite as sickening... But wait until you see the Ouroboros.
  • Ouroboros: All the fragmented Model Ws can merge to form a massive floating structure called this.
  • The Plan: Implied; Model W is most likely keeping the Gambit Roulettes of all the other major players in the story spinning away, waiting for somebody or something to fully resurrect it.
  • Powered by a Forsaken Child: A variation; in the first game, Serpent feeds the Model W Core with the Cyber Elves of the people who are filled with fear and terror before they're killed, to activate it. And what ultimately finishes the job is Vent/Aile's raw hatred for him being absorbed.
  • Red Baron: "The Evil Mega Man" for the fragment forms, though it's also known as "The Ultimate Mega Man" and "The Mega Man King" for the Core forms.
  • Sealed Evil in a Can: Many, many, many cans.
  • Womb Level: The second half of Ouroboros runs with this theme, what with the giant beating heart-like mechanism looming in the background. After Albert dies, it promptly stops and turns the entire interior of the place a dull gray.
  • Your Soul Is Mine: It eats the souls of those who are consumed with fear or hate, as Prometheus and Pandora learn too late.

    Model O
Your reward for conquering ZX's Bonus Bosses, Omega's final form as Zero's original body, or, if you have copies of Mega Man Zero 3 and Mega Man Zero 4, half of Weil's Numbers and half of the Einherjar. No small task, as Omega is no longer a pushover by any stretch of the imagination. Double Megamerges with Model X to play as a near-exact replica of Zero from his series and break what's left of the game over your knee. (Which isn't much — you can only receive Model O on a cleared save file.) Like the boss you get it from, it's a (presumably) non-canon fanservice extra.
  • Ambiguous Situation: It's not entirely clear if Model O is fully non-canon and simply fanservice material or if it actually exists in the ZX timeline. Flammole's words imply that at the very least it does exist, though whether or not Vent/Aile canonically obtained it is up in the air.
  • Awesome, but Impractical: Its full buster charge + down button has the user unleash a barrage of lasers that go up and down around him (think Zero's Rekkoha). Thing is, it doesn't do that much damage and the user is vulnerable and can't move for a few seconds after it's launched.
  • Bragging Rights Reward: One that packs a hell of a punch, though.
  • Endgame+: Only in Normal or Hard difficulty.
  • Fire, Ice, Lightning: its Overdrive Mode lets it access all three kinds of elemental attacks: a fiery Shoryuken, a midair rolling slash that shoots ice shots all around the user, and an electric Sword Beam.
  • Foreshadowing: Model O's existence is actually hinted at in the story with Flammole's first battle, as he was ordered by Serpent to dig and unearth a Biometal detected near the volcano but found nothing and even wondered if it was really Model W he sensed or "something else" before perishing. Word of God (i.e Inti Creates staff) confirmed that it's meant to be a "giveaway". And note that, in the map, Area K (where Flammole is fought) is directly above Area N (where Model O is found).
  • Ground Punch: 3 of its attacks in Overdrive Mode are this, where the user punches the ground to create bursts of energy. One causes rocks to fly away from the user, damaging enemies if hit; the other (done after half-charge) is stylized after X series Zero's Rakuhouha; while the last one (done after full-charge) takes cues from the Rekkoha.
  • Infinity+1 Biometal: And Purposely Overpowered.
  • Palette Swap: Recycles Zero's sprites with Omega Zero's palette and buster shot sprites.
  • Previous Player-Character Cameo: Controls identically to Zero series Zero, right down to the extra range on his saber slashes (Model ZX has a shorter reach), plus ZX's highly spammable spinning slash, just to be sure it makes ZX obsolete altogether.
  • Red Baron: "The False Mega Man"
  • Super Mode: It has an Overdrive mode like the Four Guardians, which never runs out, and augments all of his attacks, as well as somewhat changing its playstyle into X series Zero note  with some original attacks from Omega Zero added, including the infamous double-charge buster + Sword Beam combo.
  • Super-Powered Evil Side: Official artwork shows Vent and Aile in similar poses to Prometheus and Pandora, respectively (probably alluding to the original Omega's Ax-Crazy personality), although gameplay-wise it simply serves as a more powerful alternate to Model ZX.
  • Sword and Gun: Just like Model ZX, Model OX is armed with a gun and sword.

    Model a 
Your reward for obtaining all 24 medals in ZX Advent, allowing Grey/Aile to A-Trans into an 8-bit version of Model A. Like ZX's Model O, a (presumably) non-canon fanservice extra.
  • Joke Character: While Model a is small enough to go through small spaces that normally require the untransformed or Hedgeshock forms and can still Wall Jump, its dash is replaced with a slide and it cannot use charged attacks, Homing Shots, or the Giga Attack.
  • Red Baron: "The Ancient Mega Man"
  • Retraux: Aside from looking like Model A in the style of the 8-bit games, Grey/Ashe only makes various beeping sounds from those games while in this form, such as landing on the floor, shooting, etc., and basically plays as Mega Man did in Mega Man 3.


How well does it match the trope?
