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, Mega Man X DiVE), 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. They^note (or rather, one of them — Aile in Grey's route, Vent in Ashe's) return in ZX Advent and work with Grey and Ashe to put an end to Model W once and for all.

---

• Adaptational Badass:
  • In a bonus chapter of the ZX Advent manga Aile appears as Mega Man Model O and stands ready to fight Prometheus, Pandora, and the other enemy Mega Man alongside Grey after Prometheus blows a hole in the Guardian airship.
  • In gameplay, Vent/Aile can only fight while Megamerged and don't even carry a weapon in their humanoid form, though this is also because the security forces in Inner Peace will react with hostility to any detected weapons. In Mega Man X DiVE, Aile can fight just as well as any other playable character in her regular humanoid form, with Model ZX being her Super Mode.
• 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, they get the X-Buster as their starting weapon. Notable in that they can charge it up to two levels, firing them both at once for maximum firepower or keeping the second shot in reserve.
• Badass Adorable: Both characters in ZX start as 14-year-olds who end up wielding the powers of legendary Reploids and stopping a madman from trying to become God.
• 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: To a degree, they act like this towards Grey and Ashe after meeting them in Advent via giving them advice based on their own experiences and helping them in their journey. Aile is more successful in that regard with Grey than Vent is with Ashe since Grey directly references what she teaches him during the final battle.
• Big Damn Heroes:
  • 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.
• Breakout Character: Although Vent is meant to be the default protagonist of ZX, his female counterpart Aile has gotten more attention by fans since the game's release, likely due to the fact she's the first female "Mega Man" and that she's not the butt of the jokes in official tie-in media like Vent. In Mega Man X DiVE, Aile is made as a playable character over Vent, and one of two representatives of the ZX series, the other being Pandora.
• Brought Down to Badass: When they fight Grey/Ashe in Advent, they only have access to Model ZX since the four Guardian Biometals were stolen and given to the enemy Mega Men. They still give Grey/Ashe (who at this point has in addition to Model A has the A-Trans of not only said four enemy Mega Men, but also five Pseudoroids Aile/Vent never fought against) a decent fight, and during the final battle Aile/Vent fight evenly with all four enemy Mega Men off-screen to a stalemate while Grey/Ashe deal with Albert.
• 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, since it gets blown up by Galleons. 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.

• Expository Hairstyle Change: In ZXA, Vent grows his hair out to the point that he's now similar to Giro while Aile has a waist-length ponytail.
• Fighting Your Friend: Against Giro. Serpent, you bastard.
• Foil: Aile worries as she learns more about Serpent's past (him being a Guardian and that he was a Maverick raid survivor) that the eerie parallels between them mean ultimately she'll end up no better than him. Prairie and the Biometals make it clear they're Not So Similar, however, and that as long as she holds true to herself and remembers she has others to rely on she'll never fall down that path.
• Guys Smash, Girls Shoot: Zigzagged. Vent is often portrayed in official arts as using the saber form of Model ZX's weapon, while Aile uses the buster form. However, Vent in official art is the one who prefers using Models Hx (the Dual Wielding swordsman) and Fx (the Guns Akimbo Knuckle Busters), while Aile prefers Models Lx (who despite being the "feminine" Mega Man has exclusively a halberd) and Px (who uses kunai by the truckload). Of course, that doesn't give any difference in gameplay.

• 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.
  • 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.
• 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.
• Heroism Motive Speech: They give these to Grey and Ashe after being asked why they're fighting Model W and initially making it seem like they want Revenge for all the friends they've lost against it and the Mavericks. The speeches are so good it gets the Model A Mega Man to think hard about their own reasons for fighting.
  Aile: No... I just don't want anymore people to suffer like I have. So I decided to destroy all Model Ws in order to put an end to the Game of Destiny. I decided to become a Mega Man because I wanted to help people. You're fighting because you're trying to find out who you are, but don't forget. Only you can decide your own destiny. No matter what anyone says you are. The power you contain within is the key to creating your future. That's what a special person said to me.
  Grey: My destiny... My future.
  Vent: No. You can't defeat an enemy with hate... You just make more enemies. I want to use my power for something I believe in. That's why I made that promise to my friends, to be the Mega Man that protects them. Mega Man power is strong. Strong enough to change the world. But, there's one thing it can't change... that is our own destiny. You have to use your own power to do that. Ashe... Don't lose yourself in the power.
  Ashe: How can you even say that and keep a straight face... But I like that... Those are good words to live by.
• Hot-Blooded: Vent in ZX. He mellows out considerably in ZXA, but shows a few traces of his previous hot-headed nature.
• I Am Who?: One of the more noticeable divergences between Vent and Aile's narratives is that Aile finds herself questioning who exactly she is and why she's so special upon learning that Giro was always a Guardian assigned to watch over her, Prometheus taunting her about her ability to join "the game", and finally Serpent's revelation that she has the blood of the man who made Model W flowing through her veins. Giro is the one who reminds her that regardless of who she is or who she's tied to by blood, she's the one who decides where her destiny leads, and it's this lesson she takes to heart and passes on to Grey in Advent.
• 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. When you come back this way, you can get up to the cliff yourself and realize by doing some rough calculations by using their sprite as a reference they must have fallen at least thirty feet to the ground on their back and shrugged it off with minor discomfort. Keep in mind, this is before they get Model X.
• Mirror Character: Invoked by Aile in a more positive direction in Advent, as she replies to Grey's question about why she's fighting Model W is that it's just like him: before she knew it, she was just caught up in it and decided to fight to help people.
• Off Screen Moment Of Awesome:
  • Between ZX and Advent, Aile/Vent have been working with the Guardians to hunt down and destroy any Model Ws they can find to put an end to the Game of Destiny. According to Rockman ZX Gigamix, Aile had destroyed at least 11 of them, including Serpent's.
  • 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 Prairie is Alouette, definitely showing that Model W is what's left of Ragnarok after Dr. Weil fused with it, and confirming that Ciel founded the Guardians and made the Biometals while Aile's focuses more on the present and future such as how Serpent was formerly a Guardian, Ciel's message revealing how she made the Biometals from Model W's data and musing over the "Chosen One" could save or destroy the world, Prometheus's musings on "the game", and 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.
• 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.

• Shoryuken: An additional saber technique for Vent in ZXA. He can also fire a large Sword Beam when he does so.
• Single-Stroke Battle: They destroy the Spidrill Neo, empowered by a Model W, with a single aerial slash after it had just endured a huge beatdown from Grey/Ashe without stopping.
• Stock Shōnen Hero: In the manga adaptation of the first game, Vent is depicted as being significantly goofier than he is in the game with a love of eating and a serious case of Chronic Hero Syndrome. This makes him much more like your average manga protagonist than the more serious version of him from the games.
• 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: 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.
  • For the curious, compare their image above and this◊.
• Time-Shifted Actor: Since Vent's a grown up in Advent, Kenji Nojima voices him instead of Sanae Kobayashi.
• Tomboy: Aile in the first game. More of a Ladette in the second, but we don't get much characterization in that one.
• Tomboy and Girly Girl: Aile is a tomboy to Prairie's girly girl.
• 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.
• Was It All a Lie?: Aile wonders this when she learns about Giro being a Mega Man and that he was assigned to watch over her, questioning if everything he did was just "the mission" and if he actually cared about her. Prairie and Giro as a Cyber Elf make it clear that he always loved her.
• 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.
• World's Strongest Man: By the end of ZX, they're definitely in the running for it given that with the six Biometals they implicitly possess the powers of X, Zero, and the Four Guardians at their command, and depending on how one interprets the canonicity of the fight they're even stronger than Omega Zero, the strongest Reploid of the Zero era. Even in Advent with only Model ZX they give Grey/Ashe a hard fight, take down a Model W-empowered Spidrill that endured a beatdown from Grey/Ashe with a single well-aimed slash, and can stalemate all four of the enemy Mega Men at once.
• 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.

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.

---

• Action Girl: Is this through and through. Her intro scene features her dropping through the skies and safely landing on an airship a far way below before she becomes a Mega Man.
• Berserk Button: Ashe has a very devil-may-care attitude and tends to just roll with the punches - until people start trying to dictate her life, challenge her independence, and marginalize her. Ashe's final battle with Albert is effectively two orators shouting down the other person's ideal and viewpoints as the barbs get increasingly personal, not helped by the fact Ashe is fighting the man who took everything from her merely as an experiment to set up the Game of Destiny.
• Chain Lightning: Her Homing Shots' ability (minus the lightning elemental part), which involves her targeting up to 8 enemies and then firing a lightning-like beam to the nearest targeted enemy which will jump to another targets, one-by-one.
• Chronic Hero Syndrome: Ashe will snark the entire time, but her general care for others and their well-being will cause her to cross an entire burning oil field to save the lives of people who previously tried to gun her down. This can also be invoked by having Ashe track down the hunters she was with at the start of the game who got separated by Prometheus' attack; nothing forces her to go on this quest, and she gets nothing for it directly, but it's still an option for her to pursue. This is one of the primary tropes that help establish Ashe as a hero and not just a selfish thrill-seeker.
• Dark and Troubled Past: She's the Sole Survivor of her Doomed Hometown due to a Maverick attack. The Hunters guild then found her and took her under their wing. Despite this, Ashe is optimistic and doesn't let it get her down; Ashe does admit, however, to being a thrill-seeker partially so that she can make a history for herself, this desire partially spurred on by the many gaps in her past.
• Decomposite Character: Axl's character traits have been divided between her and Grey. She receives his outgoing personality and playful, nonchalant approach towards combat.
• Early-Bird Cameo: Was first referenced in the ZX Drama CDs while Aile, Praire, and Fleuve are out shopping, where a Hunter yells for her to leave the store only to realize she's not in the place the protagonists are at.
• Empowered Badass Normal: From the get-go, she's an Action Girl who willingly jumps off of an airship into the middle of an armada, destroys a giant Mechaniloid with a mere buster gun, and never loses face, even when confronted by Prometheus. And she's an augmented human just like anybody else...before she received the Model A.
• Establishing Character Moment: Ashe gets fed up of waiting to get to the front of the fleet of Raider ships where the Hunters know the cargo they're after is, tunes out the other Hunters transmitting to her from inside their own ship, quickly assesses where her ship is in regards to the raider ships, and then leaps down several hundred feet with a cocky smile on her face before actually sticking the landing on the Raider convoy, no harm, no foul. From there, she gets in an argument with Prometheus and walks away from the incident alive. The entire section shows how Ashe moves to the beat of her own drum and quickly establishes that she has a ton of potential already.
• Experienced Protagonist: Even before getting Model A, Ashe was a Hunter of no small ability or pluck. In cutscenes, though her dialogue mostly elicits the same responses from Model A and others as her counterpart's, she tends to be a bit more on the ball with the state of the world and what's going on.
• From Zero to Hero: Ashe's motivation. She's not quite at 'zero' given she's an accomplished Hunter, but she has yet to hit her big, world-changing score on the job, and needs to make it so her name will be known. This quality, her thrill-junkie antics, and an earnest desire to help people is what gets her an in with the Sage Trinity, the people in charge of the world, and allows Ashe to start putting her name out there.
• Gender Bender: Inevitable whenever she transforms into a male Pseudoroid or Mega Man.
• Genki Girl: In contrast to Grey. Especially poignant because Ashe has an even worse past than her counterpart, in that Ashe has a past to suffer from at all, but doesn't let it get her down.
• Glory Seeker: The reason why she became a Hunter, and why she takes to the role of a Mega Man with gusto. Since no one, including herself, knows what her past is, she wants to instead be remembered in the history books so no one can forget her.
• Guns Akimbo: Same as Grey.
• Hartman Hips: Like Aile, it's more pronounced in cut-scenes.
• The Hedonist: While also spurred on by her need to learn her past, most of Ashe's actions come down to being a Glory Seeker thrill-junkie who has a lot of fun tearing through mavericks and getting booty. Her original reaction to Model A begging her not to give him up to the villains is to explain to him she'd never do that - because he's her booty and makes her super powerful.
• Jumped at the Call: Something that separates Ashe from a majority of her predecessors and successors that hold the title of 'Mega Man' throughout the franchise is that she actively wants the life Model A gives her. Even before Model A entered into Ashe's life, she lived a life of thrills and adventure, working with glorified scavenger-mercenaries due to the Hunter occupation's chance to get good hauls and, of great importance to Ashe, put their names out there as famous heroes and legends. This trait is a core aspect she shares with her inspiration, Axl.
• I Just Want to Be Special: She just wants people and history to remember the name Ashe and become a famous Hunter, as well as writing her own story about her adventures.
• Image Song: A vocal version of her first stage theme ("Through the Lightning") appears on ZX Gigamix, titled "Be One."
• The Lad-ette: She was raised by mercenaries, after all.
• Legacy Seeker: What Ashe wants more than anything is for her name to go down in the history books so that people will remember her name.
• Little Miss Badass: She's 15.
• Made of Iron: Falls hundreds of feet onto a Raider airship from her own ship and sticks the landing like an average day, then survives being attacked by Prometheus and presumably the damage that ended up causing the main Raider ship to crash into the Oil Fields. Then there's the fact she survives a direct hit from Prometheus' Sword Beam, which damaged the large reinforced container behind her containing Model A and which outright killed Master Albert's fake body.
• Nice Girl: The main thing separating her from the selfish ambitions of her ancestor is that she has no desire for the sort of power the villain is after. Though both are ambitious, Ashe notably refuses to put innocents in danger to get ahead and abhors the idea of forcing others to live life according to her whims. In point of fact, her primary means of putting herself out there as a Legacy Seeker is being a hero who protects the weak and makes a name for themselves opposing philosphical mad men like Master Albert.
• "Not So Different" Remark: Gets this from Albert at the very end; her Secretly Selfish remarks about how he has no right to end her story causes him to ask if that's her best answer, and that she is definitely one of his creations because of it. She doesn't bother with a retort or thinking about it.
• Power Copying: Same as Grey.
• Quest for Identity: The people, and even herself, don't know who she really is, though this doesn't bother her nearly as much as Grey. Still, once Albert practically dangles that knowledge in front of her it starts coming up full-force. Her adventure later reveals her identity: the great-granddaughter of Albert.
• Red Oni, Blue Oni: Actually forms such a pairing with Vent, of all people, largely because he's cooled down since the first game. Both have the same love for exploration and action, but Vent's calmer, more impassioned arguments actually tend to win the thrill-seeking Ashe over. Though Ashe mocks Vent for giving cheesy speeches, the intent behind his speeches influences her greatly, and allows Ashe to let go of some of the more vindictive traits Prometheus accused her of having at the Control Center. Which is fitting, given the relationship Zero and X had with Axl centuries before.
• Reflecting Laser: Her charged shot.
• Schrödinger's Player Character: Played straight, then momentarily averted — in Ashe's game, it's hinted at one point that Grey still went through his intro stage, but that's about it.
• Secretly Selfish: She wants to save people just like Grey, but unlike him, who wants to honor how the Hunters saved his life despite not knowing who he was by saving others in a similar way, Ashe does it partially because she wants the story of her life to read like a hero's. Atlas even asks her if she thinks just because she became a Mega Man that suddenly she became a hero, and Prometheus gives a speech about how she's trying to rationalize her actions by calling herself a hero.
  • This is spotlighted in her confrontations with Albert, largely because Albert insists that Ashe's role was as a bit part in his life. As Ashe's selfish, glory-seeking tendencies come from her pathological need to give herself a role and a story to insert meaning into her existence, Albert's attitude sets her right off, leading her to rant at him about how the adventure is her story.
• Short Tank: More so than Aile.
• Skewed Priorities: When she wakes up in the infirmary of Hunter's Camp and Nicol lets her know they patched her up and even recovered the Biometal to take to Legion, her reaction is surprise and anger they're just gonna take their bounty out from under them instead of, you know, being grateful she's alive or even asking about where Lazarus and Red are. Nicol lampshades it by asking if that's what she's worried about and when he plainly states he's willing to give it up if means not being targeted by Prometheus or the Mavericks, Ashe outright calls him "pathetic" and that she'll go it alone with the train to Legion to get her bounty if need be.
• Smart Bomb: Same as Grey.
• Spanner in the Works: Albert admits that he was taken by surprise that a distant descendant of his would suddenly come in and join the Game of Destiny.
• The Unchosen One: Ashe is the only Mega Man that Albert did not intentionally create, but she can Megamerge with Model A because she's Albert's distant relative.
• This Is My Story: She says this twice, once after defeating Albert ("You're no Mega Man king...You're no god...You were gonna destroy the world...You were gonna end the story...You're not the one to make that decision! This is my life, my story!") and when saying goodbye to Vent at the end ("We can meet anytime...Because this is our story!").
• Tomboy: More so than Aile.
• Transhuman: Most humans in the setting by the time of the ZX series are this to some degree, as they are given bodies that make them equal in every way physically to machines so long as they train themselves, but Ashe stands as the poster girl for what these bodies are capable of in the setting with her opening free-dive stunt. Additionally, she goes further and really pushes the boundaries of what 'human' even is by incorporating a mechanical evolution in her body with both Model A and its A-Trans ability, given she can become Buckfire and other Psuedoroids (which are explicitly data-copies of full machines) and still switch back to her human form by disengaging from Model A. Her counterpart, being a reploid, and her predecessors, lacking A-Trans, can't compare.
• Tomboyish Ponytail: It's what distinguishes her from Grey when in Model A form.
• Unwitting Pawn: Same as Grey below.
• Walking the Earth: Just like Grey, she decides to travel the earth in search of more adventure (and booty).
• World's Strongest Man: By virtue of defeating the eight Pseudoroids, the four enemy Mega Men (who implicitly should be on par with the Zero-era Four Guardians), Vent (granted Worf Had the Flu is involved since he only had Model ZX, but he still fought all four Mega Men to a standstill), and ultimately Master Albert, Ashe could easily call herself the most powerful being of the post-Zero era. Of special note is the fact she can fight Prometheus and Pandora to a standstill, something not even Vent or Aile were ever shown to be capable of, as they'd previously retreat from any battle with Vent or Aile explicitly because their objective was reached or they grew bored.
• Younger Than They Look: Ashe is fifteen, but her confident, cocky attitude, her character art, and especially her in-game sprite make her look and seem more like she's in her early twenties.

Grey

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 Dissonance: It's all but outright stated that Grey's personality had his mind control been completed would have been much different than what he developed over the course of the game. Albert's dying musing on whether or not "the other me" would have given him the same "No More Holding Back" Speech all but indicates he would basically been "Albert 2.0", which makes sense since he was the backup/spare body.
• 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.
• Clone Angst: 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.
• 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.
• Flawed Prototype: Of Albert's backup bodies, albeit only because he was awoken prematurely.
• 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.
• Homing Lasers: Grey's Homing Shot takes the form of up to eight purple lasers that curve through the air toward his targets.
• Image Song: A vocal version of his first stage theme ("Destiny") appears on ZX Gigamix, titled "Believe in Myself."
• Irony: Grey is rough around the edges, but does come to respect others as well as learn what it means to be a hero in his growing urge to help people out. This makes him the polar opposite of his origin, Albert, who is not only maniacally evil but also absolutely and utterly petty towards Grey for being a failure.
• 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 from Dogu the Giant 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. Then there's the fact he survives a direct hit from Prometheus' Sword Beam, which damaged the large reinforced container behind him containing Model A and which outright killed Master Albert's fake body.
• 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.
• 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.
• Phrase Catcher: Nearly every single villain refers to him as "Defective", with Albert taking special pleasure in using the phrase once he outs himself as the Big Bad trying to get Grey killed. Even in defeat, Albert can't help but call him the "Ultimate Defective" out of sheer spite for defying him.
• 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, and the crashed Raider airship in the Oil Fields is the very same one Ashe attempted to board (plus the remains of her intro boss can be seen in the distance).
• Screw Destiny: This is his eventual response, with a bit of prior mentoring from Aile, to his Clone Angst.
• 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.
• Ultimate Life Form: By technicality, as Grey is Albert's back-up body and thus the Plan B to receive the power of Ouroboros, he's essentially a "spare Ultimate Mega Man" in the making. In the end, however, Albert spitefully refers to him instead as the "Ultimate Defective" for managing to defeat the power of Ouroboros, that of a god's, yet still utterly rejecting the destiny Albert set for him.
• 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.
• World's Strongest Man: By virtue of defeating the eight Pseudoroids, the four enemy Mega Men (who implicitly should be on par with the Zero-era Four Guardians), Aile (granted Worf Had the Flu is involved since she only had Model ZX, but she still fought all four Mega Men to a standstill), and ultimately Master Albert, Grey could easily call himself the most powerful being of the post-Zero era. Of special note is the fact he can fight Pandora and Prometheus to a standstill, something not even Vent or Aile were ever shown to be capable of, as they'd previously retreat from any battle with Vent or Aile explicitly because their objective was reached or they grew bored.
• 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.

Allies

Girouette

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, having raised them ever since the death of their family and acting as a mentor to them. It's clear he's always wanted the best for them, and even seems determined to take them under his wing as a fellow Mega Man. Unfortunately, the villains have their own ideas.
• Big Damn Heroes: Pulls this on the second boss of the game by leaping in from offscreen with a charged saber.
• Brainwashed and Crazy: Thanks to Serpent and Model W, Giro is controlled and forced to fight Vent/Aile at the end of the last tutorial stage. They manage to Beat the Curse Out of Him, but then Serpent kills the heavily-wounded Giro.
• Dark and Troubled Past: Prairie's words to Aile about how she realized what was so significant about Aile and why Giro was ordered to watch over her when she first saw Giro Megamerge indicates that like her and Serpent, Giro was a survivor of a Maverick raid.
• 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, long hair, Mind Controlled to fight Vent/Aile, and a Sacrificial Lamb are all traits that were directly lifted from Zero. They also share the same seiyuu, Yuto Kazama.
• 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 slaughters him.
• In-Series Nickname: He's referred to as "Giro" by the Guardians, but most noticeably by Prairie and Aile. Vent, meanwhile, almost exclusively calls him "Boss".
• 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. He does become a Cyber Elf, though.
• 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" and carve out their own futures for themselves and the world.
• Theme Naming: His name is French for "weather vane," fitting in with Vent and Aile.
• Trademark Favorite Food: Coffee, apparently.
• Vitriolic Best Buds: Giro describes his relationship to Vent in this manner at the end of the game compared to his more patient and kind one with Aile, outright stating that Vent would drive him crazy with his antics and disrespect which is reflected in his much harsher attitude. Despite that, he never stopped loving Vent.

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.
• Butt-Monkey: One of the generic soldiers, Maquereau, has the misfortune of often ending up in a life-threatening situation, be it getting smashed by the Giga Aspis in the intro, being shortly afterward injured during the attack at Area D, or ending up at the fire rescue mission in Area G and needing Vent/Aile's help.
• 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. Probably best shown if you talk to him at the earliest opportunity as Aile, where he tries to charm her, but ends up accidentally calling her "Earl" instead of "Aile" when trying to recall where he's heard of her before working at Giro Express.
• Cloud Cuckoolander: Truite is a downplayed example. While he's not out-and-out weird he tends to space out and miss obvious cues, and no one really has the heart to tell him otherwise. He's also the subject of a quest line where he asks Vent/Aile to deliver letters to a townsperson named Melody that he got Love at First Sight at, but all of his attempts to come off as romantic fall flat due to how he words things, and it never occurs to him how she grows more exasperated back that he might want to change tracks.
• Cool Airship: Guardian Base, which doubles as HQ.
  • All Your Base Are Belong to Us: At the halfway point of ZX, Guardian Base is invaded by Mavericks led by Prometheus.
• 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.
• 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.
• Foreshadowing: If you talk to Carrelet at the earliest possible opportunity, he'll mention about how he's waiting on Anguille to finish making a chip for him. Talk to him again after receiving Model ZX, and he'll give Vent/Aile the Eraser chip.
• 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, the Extender and Wind Boots respectively.
• The Medic: Muguet and Rose serve this role as the the head and assistant nurse respectively. Muguet is noted to be a rough but ultimately caring doctor, while Rose is the well-meaning but shy one.
• 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.
• Sequel Non-Entity: Although their airship makes an appearance, none of the guardians show up in Advent and there is no explanation to their whereabouts.
• 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 (especially Vent/Aile once they join) and is always chipper.
• 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.
• 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.
• Totally Radical: Morue, despite having the generic male Guardian outfit, is characterized by calling Vent/Aile "dude/dudette" and using other lingo such as "totally".
• You All Look Familiar: Played with. Most of the Guardians get unique sprites, and the ones that don't are usually justified by wearing the full uniform, but it's noticeable in that the generic female Guardian sprite is the same red-haired ponytailed character with her visor up and shared across three different characters (Oeillet, Chêne, and Platane). Possibly lampshaded by Oeillet, being the first and most prominent of the three by virtue of appearing the most in the story and side-missions, when she mentions she hoped she would have left a better memorable impression on Vent/Aile.

Prairie

Voiced by: Ryō 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.

---

• Big Good: As the current leader of the Guardians, Prairie is Vent/Aile's boss, the highest authority figure that knows about the Mavericks and determined to stop them, and acts as something of a Cool Big Sis with whom they can have personal talks about their doubts with.

• Cleavage Window: Odd example that overlaps with Under Boobs. Her top covers everything except the front of her breasts. She's still wearing spandex, but if the art director is to be believed, that's what counts for skin in the ZX universe.
• Future Badass: If she is indeed Alouette (and frankly, who are we kidding?), she must have taken at least a few levels in badassery, going from Ciel's Tagalong Kid to The Captain of The Guardians.
• Girls Love Stuffed Animals: She has many on her room. In particular, she's always seen with the one in the image above, practically being her Iconic Item. Notice anything familiar with that toy?
• The Leader: Of the Guardians.
• Loving a Shadow: Hinted to have fallen in love with Giro because he reminded her of someone she knew in the past.
• Older Than They Look: Is revealed to be over 100 in Vent's scenario in the first game. On top of that, Prometheus (again, in Vent's story) points out that Prairie is not of this time.
  Prometheus: Oh, you know her? Well then you must not be of this time either...Haha...What an interesting little connection you two have!
• Precious Photo: Several in her room, of Ciel, Zero, the Resistance, and her younger self.
• She Cleans Up Nicely: One of the Gigamix drama tracks is devoted to Aile dragging the workaholic Prairie to the outside world and becoming prettier like this.◊
• She Is All Grown Up: Not to the extent of Vent and Aile, but Prairie is all but outright stated to be Alouette from Mega Man Zero. Though her end result isn't quite as...grown as Aile's, but assuming she was Alouette, she did some damned impressive growing since the last series.
• Tomboy and Girly Girl: She is a girly girl to Aile's tomboy.
• Voice with an Internet Connection: She usually guides Vent/Aile through the stages via audio communications.
• What Happened to the Mouse?: Vent/Aile becomes the leader of the Guardians in ZX Advent, but they make no mention of Prairie's whereabouts, let alone name-drop her.

Master Mikhail

Voiced by: Chō (JP), Walter Roberts (EN)

The third member of the Sage Trinity.

---

• Cool Helmet: It's shaped like a golden mask with three eyes. Though considering he's a Cyborg, that might very well be his real face.
• Cool Old Guy: Wisecracks and jokes quite a bit with the heroes, and is the most down-to-earth out of the Sage Trinity. He even gives Grey/Ashe a consoling pep-talk after Prometheus and Pandora destroy the computer that hacked Legion and thus denying them the chance to search it for any data on themselves.
  "Don't feel so bad. Even without data, you are very real and you exist in this world. The proof is in the fact they went through so much trouble to keep you from seeing the data."
• Ornamental Weapon: He's depicted carrying a small sword/knife that apparently doubles as his cane, but never uses it.
• Reasonable Authority Figure: Seems to be the only member of the Sage Trinity that doesn't want to try and restart the world.
• Uncertain Doom: With the secret ending of ZX Advent revealing that Master Thomas was evil in front of Mikhail and the four enemy Mega Men at his side, it is unknown what happens to Mikhail after this point.

Master Thomas (Massive Spoilers)

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.

---

• Batman Gambit: What does he do to derail Albert's plans and make way for his own? Simply hire the Hunters and give them a huge bounty over Albert and Ouroboros.
• The Comically Serious: Compared to the wise-cracking Mikhail, Thomas is far more straight-laced, but said demeanor can get a chuckle or two out.
• Evil All Along: In the secret ending of ZX Advent, it's revealed that Master Thomas was actually just like Albert by having the same desire to remake the world. The only reason he was opposed to Albert in the game was due to disagreeing with the methods of his work and planned to do it his own way after his defeat.
• Gambit Roulette: Apparently knowing of Albert's plans, he devised one of his own to counter Albert. And it worked.
• Irony: The guy named after Dr. Light would also go rogue in his quest to "remake" the world.
• Large and in Charge: The tallest and most imposing of the three.
• Left Hanging: With ZX being left to the same fate as the Legends series, we're probably never going to find out how Thomas planned to pick up where Albert left off.
• Ornamental Weapon: He always holds a red sword, but he never uses it.
• The Reveal: The cutscene which plays after beating the game in Hard Mode reveals that he intends to continue what Albert failed to do.
• Treacherous Quest Giver: While he gives many good, generous quests throughout the game, this trope really comes to play near the end of the game; he orders the Hunters to take down Albert so he can replace him.

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 big^note implied to be Serpent. 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.

---

• Adventurer Archaeologist: Meg the "antique Hunter" as she calls herself fits this mold rather well, as she goes around hunting through ruins specifically for Lost Technology with the intent of protecting it from thieves who would sell it off on the black market. She was actually in the middle of one such hunt for artifacts when the Floating Ruins suddenly started tearing their way into the sky and tasks Grey/Ashe with collecting four artifacts (all of which are actually items from the Mega Man (Classic) period) in exchange for a Sub Tank.
• Bounty Hunter: It's in their name, after all. However, the Hunter's Guild is distinguished from the "Raiders" in that the former's actions are legally sanctioned by Legion, which gives them the benefits of high-level missions with high pay, though this means they're legally required to hand over the lost technology they collect as per the client's request rather than keep it for themselves (which is what the Raiders do). That's why they're all hands to help Grey/Ashe stop Albert when Thomas reveals he officially sanctioned the operation, bounty included.
• Cheerful Child: Several, such as Chris, Blossom despite her mom being dead, and Sharon (who's probably a pre-teen, but still counts).
• Forgotten Fallen Friend: Played with by Nicol, Lazarus, and Red, the three Hunters who were with Ashe in her story. While Nicol is the only one who apparently survives Prometheus' attack and Ashe can take a quest from him to find Lazarus and Red, their relevance to the main story ends with the intro and Ashe doesn't even need to find them or gives them much mention past that point, with them effectively just becoming NPCs she can chat with. They don't even appear in her ending to replace the three named Hunters who go to stop Ouroboros.
• Freudian Excuse Is No Excuse: Tina recounts how when she was a bandit, she would often tell herself it was the only way she could make ends meet. In the present, she admits she was just trying to justify her actions to herself to assuage her own guilt.
• Good-Guy Bar: Technically a cafe, but Building 01 is the main relaxation area for the Hunters owned by Jim, who retired from the life believing he could make a place for his fellows to enjoy themselves in their downtime. This is also where Ward is, who takes the bounty contracts on defeated Psuedoroids and pays Grey/Ashe their share. A Reploid Hunter named Nick makes a smaller cafe later on if you talk to and complete his sidequest where he sells E-Tanks.
• The Gunslinger: Richard claims he's the best Hunter in the whole camp when it comes to wielding a Buster and holds the record at the firing range for 100 kills. Grey/Ashe being the Model A Mega Man, of course, can't let that slide and they have the option to challenge that record for 100 E-Crystals.
• Huge Guy, Tiny Girl: Warren is one of the tallest and muscled Hunters in the whole game that towers over Grey/Ashe and even some of their Pseudoroid forms, and his young daughter Blossom is so small that she can comfortably be held to his chest with one arm.
• Intrepid Reporter: Carley isn't technically a Hunter herself, but a reporter who works closely with Hunters and who admires their willingness to go out into the field and face danger for their profession. She gives Grey/Ashe a quest to drop a microtransmitter on the remains of a Mechaniloid found in the Oil Fields that she can't get to herself due to both media coverage and the dangers so that she can send in a team to properly recover it. She gives them the Frog chip as a reward.
• Otaku Surrogate: Sharon, despite her Girlish Pigtails, is still a Hunter whose has official art of her wielding a pistol and also enjoys comic books, even giving Grey/Ashe a quest to buy some at Legion and 200 EC to do it (the cheapest one is 200 EC, though you can spend more than what she gives if you're feeling generous) and gives you the Ice Boots chip for completing it.
• The Medic: Anna takes this role for the Hunters, and she's beautiful enough that at least Jim is smitten with her.
• 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 (Tina 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 mooks^note compare to The Resistance, who never seem to be able to hit anything (that or their guns deal no damage to Pantheons), 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.
  • It's heavily implied that the Hunters were the predecessors of the concept for Diggers from the Legends series.
• 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.
• You All Look Familiar: Averted. Almost every Hunter has a unique sprite of their own, with the only ones sharing sprites being the Hunters wearing the full uniform.

Villains

Prometheus & Pandora

Prometheus voiced by: Daisuke Kishio (JP), Ryan Drees (VXA, EN)

Pandora voiced by: Shizuka Itō (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.

• 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.

• Badass Adorable: Pandora, although her "adorable" overshadows the "badass," especially in comparison to Prometheus.
• Being Tortured Makes You Evil: A psychological variant, but the outcome is the same. Their lives being left on an intentionally short timer to ensure they needed constant maintenance allowed Albert to build up resentment in the duo, as did his callous decision to throw them into combat again and again. This is in fact part of Albert's plan; knowing how much they hated him, he made sure to turn their animosity against him violent so as to feed the Model Ws in his lair. Tellingly, even when they think they've killed Albert and thus would have no reason to continue hurting people, their rage and psychological damage pushes them to want to kill everything so they'd go out in one final blaze of glory.
• 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 has a tendency to do this, making up for his sister's lack of it. This is only highlighted further by the awkward voice acting in ZX Advent. His "epic sham" rant in particular has become quite legendary.
• 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.
• Combination Attack: Though potent forces on their own, when they kill Albert and thus put their lives on a timer, they stop holding back and go all out. Unlike the fight with Vent or Aile at the climax of ZX, Prometheus and Pandora actively combine their abilities for full-blown combination strikes against Ashe or Grey in Advent once their collective health bar reaches the halfway point.
• 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.
• The Dog Bites Back: Their motivations for wanting to destroy Albert, as they had been abused and underwent constant suffering.
• Dual Boss: In the first game, they just alternate their attacks. They get true Combination Attacks by Advent.
• Emotionless Girl: Pandora. She's the exact opposite of her sibling, but no less dangerous or malicious. Though when she first confronts Grey on the train, her voice momentarily takes an annoyed edge to it, as if angered Grey got away from her.
• 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.
• 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 is designed with this imagergy in mind, from his darker-colored armor, the skull-shaped helmet, his Sinister Scythe, and his Red Baron being "The Reaper".
• 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, who uses it to create a large ice sculpture that bounces around, fire ice darts, and freeze one of her Attack Drones over to ram her target.
• 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.
• Lady of Black Magic: Pandora evokes the image such that her moniker is 'Witch.' Though it's all the bailiwick of technology, Pandora puts stylish flair into producing ice and lightning and teleporting, twirling her staff artistically so as to make it seem like she's actually performing feats of magic.
• 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" in ZX, and "Trap Phantasm" in ZX Advent. The latter has a remix in Rockman ZX Gigamix album called "Trap Fanatics", and another in the Zero/ZX Legacy Collection.
• Mysterious Waif: Pandora. A notable evil example.
• Not So Above It All: Pandora normally speaks in an aloof, emotionless tone, but when confronting Grey on the train, she briefly becomes very curt and frustrated, as though annoyed she got thwarted by a defective.
• 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, which he uses to create twirling and moving fire pillars, summon Flaming Skulls that shoot small fireballs, set his Prehensile Hair on fire as he stabs it into the ground to strike targets, and launch fireballs from his scythe (though he only uses this for his diving slash down the screen).
• 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.
• Promoted to Playable: Pandora finally got to be playable in Mega Man X Di VE alongside Aile.

• Psycho Prototype To Grey, although he was intended to become just like them.
• Recurring Boss: They're fought multiple times, both separately and together, in both games.
• Purple Is Powerful: Prometheus wears purple armor as his default look (though he switches to red when he uses his Playing with Fire powers) and is most certainly one of the strongest Mega Men running around, having been in the Game of Destiny for over a century.
• 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 Oni, Blue Oni: The hammy, Ax-Crazy Prometheus is the red oni, and the stoic Pandora is the blue oni.
• Sword 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.
• Right for the Wrong Reasons:
  • After destroying the computer used to hack the Legion database in the Waterfall Ruins, they tell Grey/Ashe that they couldn't just let the Mega Man with a 5-string-victory-steak "retire" after finding any data about themselves. They meant that they couldn't let their best chance to reach Albert have any chance of stopping their quest and thus deny them Revenge, but it turns out that Grey/Ashe is the key to stopping Albert all along, so it really would have been a bad idea for them to just give up the quest at this point.
  • After apparently killing Albert, Prometheus chuckles to Model A's befuddlement over this particular twist that "[the game's] not over yet." He meant it in that he and Pandora still intend to destroy everything themselves, but in reality Albert isn't actually dead yet and thus it really isn't over yet.
• Shapeshifter Mode Lock: They're permanently bound to Model W.
• Shock and Awe: Pandora, who uses it to fire guideable electric shocks, create electric traps, envelop one of her Attack Drones to ram a target, and shape it into multiple floating copies of her staff that she telekinetically controls to fire off or act as shields.
• 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.

• 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.
• 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...
• The Stoic: Pandora is soft-spoken and generally not open about her emotions.
• Suicide by Cop: 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).
• Uncertain Doom: Their final confrontation with Grey/Ashe in the Undersea Volcano ends with the pair unconscious, and Grey/Ashe is forced to leave them behind in the Collapsing Lair as the Model Ws begin to merge into the Ouroboros. Whether or not they survived after Master Albert's defeat remains unknown.
• Vampire Lolita Archetype: Pandora's Halloween variant in X DiVE is clearly designed to evoke this image, wearing an Elegant Gothic Lolita style dress with bat motifs.
• 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" Remark 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 last words, 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.
• World's Strongest Man: In the running for it with Ashe and Grey. Like Ashe and Grey, they are the only Mega Men who never suffer an explicit onscreen loss. When Ashe or Grey fights both at once, Ashe or Grey call the fight off after a while, deciding the rationale behind Prometheus and Pandora antagonizing them is insane. Of note, however, is that this is the one time where the duo don't play off the fight as if they were holding back, and Ashe and Grey will still sound as though they can go for another few rounds if the fight persisted.
• 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.
• 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...
• 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!

Serpent

Voiced by: Kiyoyuki Yanada

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.

---

• Armed Legs: His Megamerged form has spikes on his feet that he uses to kick opponents with.
• Animal Motifs: His name is Serpent, and he not only made the symbol of his company resemble a snake in the shape of an "S", but he's deceptive and sneaky "like a snake in the grass".
• 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 Boast: In his second form, after his second health bar is taken down by enough damage, he will go into the third phase of this form and say this:
  Serpent: Korega "Ō" no sugata da! (This is the form of a "King"!)

• Big Bad: Of ZX, as his plan to dig up the Model W Core and use it to become an almighty being is responsible for much of the personal tragedy of Vent/Aile and the main conflict that must be stopped.
• Corrupt Corporate Executive: Head of Slither Inc., a massive MegaCorp 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.
• Extremity Extremist: Despite his muscular body, he only uses kicks for physical attacks.
• Final Boss Preview: He's first seen mind-controlling an injured Giro then introduced himself after he strikes him 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.
• Freudian Excuse Denial: When Aile refutes his Social Darwinist speech by stating deep down he's just a man deeply afraid of his past, himself, and what he's become, which is why the Model W fragment managed to sink its claws so deeply into him and resulted in him being Driven to Madness, Serpent claims she's sprouting nonsense and doubles down on his own claims that "evolution requires sacrifice."
• 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.
• Green and Mean: The jacket he wears is primarily green, and he's a villain.
• 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!"
• Lantern Jaw of Justice: Played with. He's got a noticeable square chin, and he was once a Guardian, but now he's a villain.
• 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 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.
  • Power Echoes: In his second form.
• 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.
• "The Reason You Suck" Speech: Gives one to Vent at the end of their battle, declaring that Vent is a naive child holding back the world because he doesn't want to see his loved ones hurt. It noticeably shakes Vent.
  Serpent: (to being called a Maverick) A Maverick!? Me!? How dare you call me a Maverick! You're the one stopping progress. You're the one denying change. Maybe you're the Maverick! People and society are destined for change! They must shed their hate-filled hearts and suffering bodies. We must move forward! We must have change!
  Vent: I will not let anyone get stepped on in your road to "progress!"
  Serpent: On a planet... life is born... humans and machines... waves of war and peace roll on. And in every age, a fool like you tries to fight it. You don't want to see anyone get hurt. You want to protect the ones you care about. You don't want to lose anything. By acting on that desire, you continue to make choices that avoid the pain. The Mega Man destined to save the world? Unchanging life... a world devoid of the light of hope. What's the point?!
• 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 involves a kicking variant of this.
• 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.
• Spikes of Villainy: His Model W Mega Man form has the noticeable orange crystals jutting out of his feet, shoulders, and forehead. His One-Winged Angel form has similar orange horns jutting out of his shoulders and head, with one green one out of his forehead.
• 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).
• Stealing the Credit: Implied to have done so with Ciel's Ciel System by curing the energy crisis that plagued the world since the Zero series.
• Straw Nihilist: After Vent/Aile beats him for the final time, Serpent tells them that their fight to protect the ones they love is pointless, as life will just go on in the cycle of peace and war. In Vent's case, he outright calls him a Maverick for prioritizing his temporary loved ones over possible grand future changes.
• 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. His closing "The Reason You Suck" Speech to Vent is mocking him for refusing to have the will and strength to change the world for the better because he wants to "protect" the people close to him and so shuns change.
• Underestimating Badassery: He derides Models X and Z as little better than "tin can scrappings" and considers Vent/Aile unworthy as one of The Chosen Many at the beginning of the game. Those very same Models and Mega Man eventually hand him his defeat despite having the awakened Model W Core on his side.
• Unperson: Despite having once been a Guardian, Prairie is in just as much shock at the revelation as Aile in her story, 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
  • Bread and Circuses: Is seen as a hero by the townspeople for having his security forces from Slither Inc. keep Mavericks at bay, and giving them access to energy sources via the Ciel System. It's revealed that he staged the Maverick uprisings himself in order to assemble a large enough number of people that he could then forcibly turn into Cyber Elves and feed to Model W, thus awakening it.
• Weak-Willed: Called as such by Prometheus, who notes that the Model W Core will devour his soul in time because he doesn't have the strength of will to truly master it. While Serpent himself denies this, the fact that he was Driven to Madness in the first place by the Model W fragment seems to indicate otherwise.
• With Great Power Comes Great Insanity: It's noted in Aile's story that giving in to Model W's influence was what gave him its power (and of course, destroyed his sanity). As he unlocks more power, he just gets crazier.
• 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, which Model W feed on and exacerbated to lead to his insanity. In addition, in the Japanese version, when denying Vent's retorts to Serpent, Serpent sounded a bit melancholy.
• Villain 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 move forward already. Noticeably, Vent can't bring himself to disagree with that sentiment, and it takes Giro telling him that he should try and change the world his way then, a way that doesn't necessarily mean bloodshed and sweeping others aside to deal with your own pain, to snap him out of it.
  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?!
• You Killed My Father: Not directly, but Serpent did organize the Maverick raid that Purprill was part of and late security response from Slither Inc. that got Vent/Aile's mom killed in Area H.
• You Will Not Evade Me: His second form can create a black hole to pull you in (or alternately push you away).

Master Albert (Unmarked Spoilers)

^{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.
• 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.
• Assimilation Plot: His lines about how the spirits of everything Model W eats lives on within himself and gives him "the power to control all life", plus his win quote in his second phase indicates that his end game is to forcibly feed every living thing to the Ouroboros before using its power to build his new world.
• 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: For ZX Advent, being the man behind the entire Game of Destiny, the numerous Maverick attacks happening, and the original discoverer slash creator of the Model W Biometal.
• Bishōnen Line: Goes from a three-headed mechanical dragon, to the vastly-powerful, nigh-angelic Mega Man Model W.
• 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."
• 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: Made all the more obvious after his reveal as the Big Bad. While speaking with a polite demeanor towards both Ashe and Grey during these times, he also takes the time to constantly belittle and taunt the latter.
• 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: Albert believes that with Model W's fully-realized power he would be able to Restart the World with himself at the reins. 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!"
• Gravity Master: Alongside Model W's own control over gravity, as shown by affecting the gravity of the Floating Ruins and giving its users the ability to leviate unaided, Albert's three-headed dragon throne is explictly stated to manipulate gravity in its Secret Disk entry, allowing it to launch a beam of energy that forcibly rips up the floor (and if it hits Grey/Ashe, it will send them flying into the air too) and create black holes and white holes while rending dimensions with its raw power.
• Greater-Scope Villain: He's the "Man who made Model W" that Serpent mentions in Megaman ZX, having created the numerous Model W fragments like the one Serpent wields, and implied to have been the one to have discovered the Model W core. As it turns out later in ZX Advent, he was also the reason for why Vent, Aile, Serpent, and the other Biometal users (sans Grey and Ashe) could Megamerge, with Albert having donated his blood to the survivors of Maverick attacks and thus indirectly allowing said survivors access to the power of Biometal.
• Green and Mean: He's a straight-up bad guy and his decoy body has long, green/blue hair. Even his true body has glowing green parts on it.
• 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.
• Hypocrite: Touts his "Game of Destiny" as a means of one Mega Man rising above the rest like a battle royale, where the winner gets to change the world in their image. The reality is he already seems to have brainwashed all the other Mega Men besides Vent/Aile, manipulated the entire conflict to get him Ouroboros, abandoned his duties with a co-conspirator in their plans to Restart the World so he could do it his way, and ultimately did virtually everything he possibly could to stack the deck in his favor so he'd be the ultimate Mega Man and champion of the game. All of this while being one of the Sage Trinity of Legion, where he can literally vote and veto world-spanning decisions into motion from the single highest position of power above all besides his two fellows. Albert had desired nothing but power for himself from the very start, and very blatantly disregards any notion of alleged fair play in favor of proclaiming himself to be a god that deserves it all. And when he loses, boy does he take it poorly.

• 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.
• Kick the Dog: Whereas he praises and treats Ashe with respect as a member of his family, he has no tolerance for Grey being an unfinished (and unbrainwashed) clone backup of his. After The Reveal, Albert straight up makes almost every sentence he has towards Grey, that isn't reveling in his own plans at least, be utterly dismissive and spiteful for the sake of it. Even his dying words after being beaten by Grey and hearing his choice to choose his own path have Albert spitefully call him the "Ultimate Defective" just as a final insult and mocking spin on the would-be spare Ultimate Mega Man refusing to play his "intended" role.

• 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.

• 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. It's also implied in Ashe's story that Albert may be manipulated by Model W, his "creation," no less.
• Meaningful Name: Knowing the full name of Dr. Albert Wily will likely tip off any long-time series fans as to which Sage is going to be the evil one, as his ambitions of pure egotism and a vie for power fit a Wily that lacks a proper nemesis to curtail his power. Of course, he's not the only evil one.
• My Kung-Fu Is Stronger 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.
• "Not So Different" Remark: While he disregards much of what Grey says as just being a fake him, his response to Ashe's victory over him involving her ranting about how he was going to end "her story" is to outright admit she is most definitely of his lineage with how selfish such a goal was.
• Not-So-Well-Intentioned Extremist: His pre-final battle speech implies that his justification 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?
• 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.

• Pet the Dog: An extremely, extremely small one when he seems to express sympathy and regret over having to do in Ashe as she's his last living descendant… before immediately subverting it by expressing how happy he'll be as the only version of himself. 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.

• President Evil: As one of the Sage Trinity, the ruling power of Legion, Albert possessed governmental power over the world for centuries, and used those connections in order to further his research and plan.
• 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.
• Red and Black and Evil All Over: His true form has long, red hair, with black metallic faceplate (albeit this is also present on his decoy body), and two black belts encircling his body, around his waist and his chest.
• 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.
• Shapeshifter Showoff Session: When Albert reveals that he possess the same Voluntary Shapeshifting as the protagonist, he demonstrates it by switching between the forms of the game's bosses and doing a little impression of each of them.
• 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.
• So Proud of You: In a backhanded sort of matter. While he is dismissive of the "ultimate defective" Grey even in his death, his last words to Ashe actually has him praising his own research and work in managing to create a piece of lineage in the long-term that managed to surpass even himself. Still gives an abbreviated version of his Sore Loser words below, though.
• Sore Loser: After manipulating the world for centuries, stacking the Game of Destiny so lopsidedly in his favor that there's no way he'd fail normally, and finally achieving Ouroboros' creation through countless Model W fragments coming together, his defeat at the hands of Ashe/Grey and Model A has him make one of the most openly spiteful and vindictive statements in the franchise towards the peace the heroes had intended to achieve.
  Albert: You can have your gentle peace... and leisurely rot in it!
• 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.
• There Can Be Only One: Not only was his Game of Destiny meant to be this, with himself being "the One", of course, but he outright tells Grey after revealing he was the spare Ultimate Mega Man that there only needs to be one such being now that the plan has come to fruition.
• Too Clever by Half: He planned for just about everything, even creating several fail-safes on the off-chance he needed them. In the end, it was some of those very fail-safes gone rogue that ultimately defeated him even by the point he believed he no longer needed them with the power of a "god" at his disposal.
• 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.
• 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 Have Outlived Your Usefulness: Implicitly does this to Prometheus and Pandora after using them to wake up Model W, and said outright to Grey at the final battle since it turns out he didn't need a "spare Ultimate Mega Man" after all.

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:

• The Kirk: Aeolus, Model H's Biomatch and the stereotypically smug and beautiful Darwinist. His plan for society, should he win, logically follows this ideology (specifically, he wants to "eliminate the fools out of this world").
• The Spock: Siarnaq, Model P's Biomatch and a stoic to the point of speaking in command prompts due to his past. His motivation is unknown.
• The McCoy: Atlas, Model F's Biomatch and a fight-loving tough broad orphan from a nation that was overrun by Mavericks. Influenced by her past, her view on the world is that the strong will survive and the weak shall perish, and thus, if she wins, she plans to use her influence to speed up human evolution by starting a perpetual war.
• Token Good Teammate: Thetis, Model L's Biomatch and an otherwise cheerful lad whose plan for society would involve the genocide necessary to satisfy his rabid environmentalism.

---

• 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) and the fact that humans and Reploids have effectively merged into a single race by the time of the ZX era, 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.
• 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, due to wielding Model H.
• Boss Rush: Subverted. Advent definitely looks like it's gonna pull this, right after the Pseudoroid Boss Rush even, but then Aile/Vent come in for their Big Damn Heroes moment and tell Grey/Ashe to take care of Albert while they Hold the Line.
• 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.
• Char Clone: Thetis, by dint of carrying Char's CCA personality as an eco-terrorist wanting to save the world—particularly the ocean—from humanity, which he has deemed untrustworthy. He lacks many of the other typical traits, however.
• 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.
• Dash Attack:
  • Atlas can charge Ashe with her Knuckle Busters in an attempt to smash her, and if she hits the wall while Ashe is on it can knock her off. In Grey's case, she combines it with her Ground Pound in that she'll dash jump towards him while launching a fire wave upon landing.
  • Thetis will use swim-dash into Grey/Ashe and use the spinning halberd move before swim-dashing away.
  • Aeolus will air-dash at Grey/Ashe to unleash the double slash.
• Desperation Attack: All four have one which they start using once they hit half-health.
  • Atlas charges up a massive Energy Ball that she fires at Grey/Ashe. Even if they dodge it, it will strike the wall and split into smaller shots that ricochet off to to try and hit them. The smaller energy balls can be targeted and destroyed with the Homing Shot.
  • Siarnaq creates three (four in Expert Mode) clones of himself that will float and spin through the air before each unleashing two kunai at Grey/Ashe. Attacking the wrong clone will simply make that one vanish, while attacking the real Siarnaq ends the move entirely.
  • Aeolus jumps into the air and summons two electric pinwheels which Grey and Ashe must dodge between to avoid being hit while Aeolus himself slowly floats back down. The move lasts until he hits the ground.
  • Thetis summons a machine from a Bottomless Pit that fires off damaging snowflakes before creating a vacuum that sucks in anything nearby (them and Grey/Ashe) to drag them into the pit. The snowflakes can be destroyed via Homing Shot.
• Dual Wielding: Aeolus, with Laser Blades, mimicking Harpuia.
• Dub Personality Change: A very minor example with Siarnaq in the Japanese and English dubs. In the Japanese Dub, he will burst out in a fit of hysterical, crazed laughter in his dialogue after he defeats the player character, showing that his friends betraying him and leaving him for dead affectedly him a lot worse than just leaving him cold and impassive, while in the English Dub, his laughter is just as monotone as the rest of his lines.
• 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 hates humanity despite his kind nature 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.
  • Aeolus takes it one step further: compare this picture of him◊ to this picture of Raika◊ from Mega Man Battle Network.
• 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).
• 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. On the surface the most cheerful and affable of the group, his deep love of nature and especially the ocean far outstrips anything he feels towards his fellow humans, to the point he plans to destroy all (or at least nearly all, if his win quote of "save what you can, then dispose of the rest" means anything) of humanity to preserve the beauty of the sea.
• 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.
• 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.
• Hand Cannon: 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, due to wielding Model L.

• 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 desecrating 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 'Em: 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, who is a rough-and-ready fighter and a war veteran who believes in a Forever War.
• 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 almost always remains slouched over, which when combined with his robotic mindset makes him come off as "off".
• 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: 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 due to wielding Model P resembles a dark-purple Cyber Ninja, complete with kunai and shuriken and the ability to use a Flash Step.
• Not Himself:
  • 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.
• Non-Standard Character Design: Siarnaq as Mega Man Model P has the most drastic differences from its counterpart used by Vent/Aile.
• 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. The closest a possible motive is suggested is in his victory quote against Grey/Ashe, where he states he will commence with the planned takeover of Legion headquarters and thus suggesting he intends to dispose of the Sage Trinity.
• 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, as a result of wielding Model F.
• 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. In his victory quote against Grey/Ashe, he mentions that will now commence with a planned takeover of Legion headquarters, which given his talents suggest that he'll get rid of the Sage Trinity next.
• 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: Zig-zagged. 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' energy 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).
• She Is the King: Whoever wins the Game of Destiny is supposed to become the Mega Man King. While Ashe isn't interested, Atlas is, and wholeheartedly seems satisfied with such a title, as her quote further up shows. Also, being a Mega Man doesn't seem to bother her.
• Shifting Sand Land: Atlas' stage, with additional crude oil mine and Raiders' crashed airship.
• Shock and Awe: Again, Aeolus, thanks to Model H's secondary element.
• Smug Snake: Aeolus, all the way, who can't go a sentence without putting down someone for perceived foolishness or ignorance while tooting his own horn since he's a Mega Man and that he could end Grey/Ashe at any time. His only on-screen fight ends in his loss, and he takes his defeat nearly as bad as Thetis does with the added bonus of This Cannot Be!.
• 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.
  • Not So Stoic: Siarnaq. See Laughing Mad above.
• Sword Beam:
  • Aeolus fires them in a style like Harpuia, but he (fortunately) cannot spam them save on Expert Mode, where he'll fire two.
  • Thetis can charge and fire a large blue energy spear projectile.
• 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 The Greek deity Helios is occasionally referred to as Hyperion, one of Saturn's many moons. 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 "defective" 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.
• 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. They are savvy enough to gang up on Grey/Ashe in the last level right before the Final Boss in response to their previous losses, but that's when Aile/Vent shows up to hold them off.
• 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.
• Villain Team-Up: They each individually correctly identify that Ashe or Grey are by far the greatest threat to them winning the Game of Destiny and becoming Mega Man King, and thus decide to set up a truce during the final level so they can overwhelm Model A. Aile or Vent stops them from actually getting to fight Model A, however. The secret ending implies this alliance is maintained following the death of Albert.
• Well-Intentioned Extremist: Thetis and Atlas, but 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, hence her solution being to start a Forever War, and the ocean's safeguarding is very Serious Business to Thetis. Given that they're using Model W to accomplish said goals, any noble intentions are undermined by their extreme methods.
• 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.
• 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), don't match the forms of the Guardians themselves, except for Atlas' ^note Like Fefnir's, her horns protrude from the front side of her helmet, while Model FX's come from the back side (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 For example, Siarnaq's scarf evolves into Model P's faceguard while Thetis' Idiot Hair evolves into Model L's single water-thruster, unlike Model LX's "twintails".
• You Fool!: Aeolus is quite fond of this phrase, to the point that addressing Grey/Ashe as "fools" becomes his Catchphrase Insult.

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:
  • An Ice Person: Lurerre and Leganchor
  • Playing with Fire: Fistleo and Flammole (the latter also has Dishing Out Dirt)
  • Non-Elemental: Purprill and Protectos; they have no special elemental attribute, but therefore no weakness.
  • Shock and Awe: Hivolt and Hurricaune (the latter also has Blow You Away)
• 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 that have no power of their own, forcefully drawing their power from Biometal fragments instead; 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.
• Two Girls to a Team: Hurricaune and Lurerre are both female.

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.

---

• Attack Drone: Hivolt can detach his legs to form these, which will then act as either Orbiting Particle Shield or Weak Turret Gun.
• Clip Its Wings: His Biometal fragment is contained in his wings.
• Curiosity Killed the Cast: References the classic phrase if he defeats Vent/Aile in their first fight.
  "Curiosity got the cat, and your curiosity just got you."
• Dash Attack: One of his default moves.
• Emerging from the Shadows: A variant. He first appears silhouetted by the setting sun on top of a wrecked generator before taking flight and descending.
• Energy Weapon: His EX Skill. Hivolt flies up to the top of the stage and fires alternating laser beams from his leg cannons and wings. In the ZX manga, these beams are powerful enough to tear through buildings and carve great tracks in the earth.
• Evil Laugh: Gives a pretty haughty one before he uses his EX Skill.
• Face Death with Dignity: As he's being pulled into Model W after his rematch, he proudly states he doesn't fear death.
• Feathered Fiend: He's based on an eagle.
• Pride: He thinks pretty highly of himself. Aile even lampshades how chatty he is. It ends up being his Fatal Flaw in the ZX manga, as Vent taking shots at his ego is part of what gets him killed.
• Razor Wings: Uses his wings as giant blades for one attack, with his third swing unleashing a Razor Wind projectile very similar to Sage Harpuia's (and by extension Model H's) similar triple slash and Sonic Boom combo.
• Shock and Awe: He charges his attacks with lightning.

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.

---

• Attack Its Weak Point: In addition to the lure's head, her larger body can be damaged while its mouth is open, although it doesn't take any more than the lure does.
• An Ice Person: She uses ice arrows, drops ice shards that turn into spikes when they hit the ground, and can fire an ice-based Wave-Motion Gun.
• Dying Curse: As she's defeated in her rematch, she only states Serpent can have her soul while hoping that Vent/Aile get squished like bugs.
• Dynamic Entry: Do enough damage to her lure to cause it to break or just stay too close to the right side of the field for too long, and Lurerre's giant fish body will lunge out to try and bite you.
• Luring in Prey: While she initially appears to be a mermaid Pseudoroid, getting drawn close enough or dealing direct damage to her weak point will reveal that its just a lure, and her real body is a massive anglerfish robot hiding offscreen. In the ZX manga, she actually disguises her lure as an injured maid in order to trick Vent into coming out on the ice before revealing herself and dragging him underwater.
• Making a Splash: Both her lure and her true body can create a whirlpool that can drag Vent/Aile in, allowing the other half of their body to unleash an attack.
• Mood-Swinger: More pronounced in the Japanese dub, but she jumps back and forth between acting cutesy and innocent (introducing herself as "the lovely Pseudoroid Model L) and violently describing how she's about to "take you apart, piece by piece" mid-sentence. It plays into her deceptive nature.
• Psycho Supporter: She heaps praise on Serpent, and most of her anger is directed at you for disrupting his plans.
• Removing the Head or Destroying the Brain: Her Biometal is contained in her lure's head. Ironic, since its only the lure and not the actual Pseudoroid.
• Unusual Weapon Mounting: Lurerre can fire a giant missile from her (real body's) mouth. You can blow it up while it's still in her mouth to deal huge damage to her.
• Water Is Womanly: She can form a whirlpool and looks like a mermaid when her real body is actually a giant anglerfish robot. She acts like an innocent girl but is in truth violent and aggressive.
• Wave-Motion Gun: Her EX Skill. Lurerre fires a large ice beam capped with a reflective shield from her lure's hands. You can try to push it back at her with your shots; if you succeed, you'll deal quite some damage.
• You Will Not Evade Me: Uses a whirlpool to draw you closer so her real body can hit you.

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.
• Counter-Attack: After he takes sufficient damage, Fistleo will occasionally turn so that his back is facing the screen with a Battle Aura. If he's attacked in this state, he will immediately retaliate.
• 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."
• 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, presumably by drawing on his Model F fragment directly, though he can't move while doing so. The amount of health he restores is doubled in Hard Mode, and he can spam this move several times in a row.
• 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. In the ZX manga, he demonstrates his power by tearing a building in two with one hit.
• 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.
• The Unfettered: In Vent's storyline, he states he will do whatever it takes to gain power, which is why he chose to aid Serpent in exchange for being upgraded into a Pseudoroid.
• 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.

---

• All Your Powers Combined: In the ZX manga, he gets his hands on Models H, L, and F and merges with them to power up to the maximum, gaining a silver body alongside increased speed, defense, and strength that lets him easily overpower Vent. Unfortunately for him, his body can't handle all four Biometals and it starts breaking down on him on its own, letting Vent finish him off.
• 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 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. Overlaps with Mook Promotion.
• Expy: 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.
  • 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.
• Helicopter Blender: She can use her helicopter blades to slice up her foes.
• 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. She even tells Vent/Aile to make sure and scream for her.
• 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.
• Silly Rabbit, Idealism Is for Kids!: Mockingly calls Aile a "little heroine" for coming to save the kidnapped citizens, while mockingly telling Vent "chivalry is dead."
• Spectacular Spinning: All of her attacks. One specific move has Hurricaune spin her whole lower body like a drill to descend on your head.
• 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 She's also, as her name suggests, based on a wolverine, the largest member of the weasel family.

Leganchor the Gelroid

Voiced by: Osamu Ryutani

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.

---

• An Ice Person: Like Lurerre, he has half of the Model L Biometal inside him, thus giving him access to Ice-based attacks. He can even create smaller ice dragons like Leviathan and Model L.
• Attack Drone: He can deploy jellyfish on either side of him that fire shots at you from above (or below, if you've wall-jumped out of the water). You can destroy them with a few hits. Crosses over with Flunky Boss.
• Combat Pragmatist: Leganchor coats the floors and walls with ice up to your maximum jump height (sans Model LX), hampering your movement and keeping you from wall jumping. You can melt them with Model F, but he'll re-coat them after a while.
• Combat Tentacles: He has 'em, and touching them while they're deployed or retracted freezes you.
• Electric Jellyfish: Subverted; he's a freezing (gigantic) jellyfish instead.
• Evil Old Folks: Leganchor is halfway senile and often comments how Youth Is Wasted on the Dumb (referring to the heroes, of course).
• Ignorance Is Bliss: Outright says this when Vent/Aile call him and the villains out on lying to the public and thus unworthy of any respect.
• Making a Splash: One of his attacks involves rising out of the water and crashing back down to create massive waves that buffet Vent/Aile if they try to climb out of the water out of his reach.
• Removing the Head or Destroying the Brain: His Biometal fragment is contained in the turbines connected to his head.
• Skull for a Head: Leganchor, though his actual head is above it.
• Stationary Boss: Leganchor is so huge that he doesn't actually move around his boss room and just spams his attacks to where Vent/Aile is, save for one move where he'll rise out of the water to crash back down, releasing giant water waves, if they try to climb out of the water out of his reach.
• Super-Strength: In the ZX manga, he's strong enough to grab and pull the entire docked and damaged Guardian Base into the water in an attempt to sink it and drown everyone onboard.
• Tornado Move: He'll use his turbines to draw you into a vortex that slowly pulls you into him, dealing damage and freezing you. You can wriggle your way to freedom if you get caught.

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.

---

• A.I. Breaker: Doing precise wall jumps causes Flammole to turn around over and over again. It looks like he's dancing to the boss music.
• 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.
• You Have Failed Me: He gets killed by Prometheus contemptuously in the ZX manga for unknowingly leading Vent right to the room in Slither Inc. where Model W is located.

Protectos the Goreroid

What's the difference between a Goreroid and All Japan Goith?

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 (bulk-wise) 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 that vanishes from sight and detonates when Vent/Aile get close. His ordinace is sufficiently powerful that in the ZX manga he singlehandedly brought down the Guardian Base 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.
• Not Completely Useless: 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.
• Two Girls to a Team: Hedgeshock and Queenbee are both female Psuedoroids.
• Undying Loyalty: While some of them are definitely more sadistic and take pleasure out of the job than others, all but possibly Vulturon are nothing if not loyal to Master Albert.

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. His Silver Medal requires only attacking his mane to beat him.
• 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.
• Boring, but Practical: His A-Trans form is exactly identical to his boss fight, sans Collision Damage. His A-Trans form is also pretty much just a bigger version of Model A with a spread gun, some melee attacks, a different wall jump, and a fire affinity. It's for these exact reasons that he ties with Argoyle and Ugoyle and Queenbee as the most useful A-Trans form in the game. The game was built off Model-A's capabilities, and his capabilities closely match Model A's.
• 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.
• David Versus Goliath: His Bronze Medal is obtained from being defeated by Hedgeshock's Rolling Dash or Rolling Spike, making him the Goliath (one of the taller/larger Psuedoroids) to Hedgeshock's David (being the smallest one by far).
• 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. The animation shows he collects his flames at the sole of his kicking foot and concentrates it into a sharp cone of fire that smashes whatever's in the way as he dives.
• 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.

• Horn Attack: He can either dash with his horn pointed forward, or do a Shoryuken with his horn. The latter can break weak walls.
• Hot Blade: He uses the Model W powering his body to superheat the blades on his arms.

• 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.
• 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. Thankfully, the fact that Model P's touch-screen kunai requires BM energy is negated by waiting for the Mercy Invincibility to wear off, so a sufficiently high gauge won't have to worry about running out anytime during the fight.
• Playing with Fire: He unleashes flame arrows and his Diving Kick is tipped with a powerful jet of flame. According to his Secret Disk, he can also superheat his blades.
• 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.
• Warm-Up Boss: Buckfire is the first boss Ashe or Grey fight with Model A, and he's built to thus teach the player how to handle fights with enemies that don't go down in one or two charge shots. His movements may seem erratic, but he'll never intentionally run into you while dashing, so most of his boss fight revolves around pattern recognition; what each attack does, the tell before he uses it, and how to evade them. For bonus points, each attack he has allows for multiple methods of dodging them.

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. That said, his Time Bomb still works, ironically making him the most useful of the A-Trans forms.
• Die Laughing: Even as he dies, he takes solace in the fact Grey/Ashe are just pawns dancing about and belts out a laugh.
• Elemental Rock-Paper-Scissors: His Gold Medal is obtained from being defeated by Queenbee's attacks only.
• 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.
• Half the Man He Used to Be: Getting his Silver Medal requires the player to finish him off with Buckfire's Dash Attack, which will result in this.
• 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.
• Sand Is Water: Being a horseshoe crab, he can dig into and submerge his lower body in sand to protect his vulnerable underbelly before unleashing his small copies, and he'll swim through it as easily as water in an attempt to ram you.
• 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 if they get close to Ashe or Grey, though they can still be dodged in this state. 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 above and his 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).
• Effeminate Misogynistic Guy: He is quite the flamboyant ferrously floral fellow (see Ambiguously Gay above), and he treats Grey and Ashe more differently than each other than almost any other character in the game does. Which is to say, he just really hates Ashe. Meanwhile, he doesn't seem bothered by Grey or any other male character at all, even when he gives a Raider a chance to slip away or he's killing him.
• Heal Thyself: He recovers some of his health while charging up his Desperation Attack, presumably because he's using some of the electricity he absorbs to fire it for that purpose.
• 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: He is based on the rose.
• 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, and once its finished any vines that were in its path will receive an electrical discharge and shock Grey/Ashe if they were touching the vine rather safely between them.
• 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. His Bronze Medal can only be won if he's killed while in his bulb form.
• Underestimating Badassery: Admits this upon his first defeat to both Grey and Ashe, though he's more loudly dramatic about how Grey's power was "so fiery" while he can only mutter about how Ashe has "the nerve" while in disbelief about her strength.
• Vine Tentacles: Rospark can weaponize his thorny vines like this. He can even electrify it.
• 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.
• Wham Line: In Ashe's story, he outright states that the "new king" he's sacrificing people to is Biometal Model W, a shocker for first-time players fresh from ZX since by all appearances Model W was already destroyed, even before they see the Model W Core the next room over to confirm it.

Vulturon the Condoroid (Condorock the Vulturoid)

Voiced By: Kishow 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: As an undead guitarist with a crazy rocker personality, Vulturon is based on fellow Capcom antagonist 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".
• Half the Man He Used to Be: The Silver Medal requires defeating him with Model H's Sonic Boom, which will inevitably result in this once landed.
• 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: 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. There is a reason why the Bronze Medal simply requires the fight lasting more than two minutes before defeating Vulturon, as it's impossible to get the Gold Medal without also qualifying for this one.
• 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.
• This Cannot Be!: Upon his first defeat, complete with a Big "WHAT?!".
  "What?! This was supposed to be Mega's death concert, not mine!"
• 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 neighboring 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: She's a Pseudoroid based off a bee/wasp and fights with lasers, missiles, and exploding bee drones. She's also likely the most Ax-Crazy of the bunch given her eagerness to watch destruction.
• Bee-Bee Gun: Deploys swarms of small bee drones from her beehive to hunt you down, which doubles as Flunky Boss. Ironically, in order to get her Silver Medal you need to defeat her without destroying any of her bee drones.
• 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.
• Energy Weapon: 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 for her EX Skill.

• 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.
• Lady of War: Queenbee speaks with a very refined tone and uses fancy vocabulary with her metaphors about bees and flowers, but she's very likely the most bloodthirsty of the Pseudoroids and fully willing to get her hands dirty in a fight.
• Macross Missile Massacre: Queenbee as a boss can fire these out of her beehive.
• Marathon Boss: While chasing her Gold Medal, at least. It technically "only" requires never harming her beehive armory and always attacking her actual body, but in practice the only move in the game that can safely harm only her main body while attached to her beehive is the Giga Crush. While she doesn't have nearly as much of a tendency to turn invulnerable like Vulturon outside of her Desperation Attack, nearly all the issues previously applicable to fighting Vulturon with the Giga Crush (including requiring all BM energy to fire it and needing to wait for it to recharge, alongside how collecting BM upgrades only lengthens this recovery period) apply. And if you do try to use alternate methods, tt should also be mentioned that the beehive has a massive hitbox of its own and Queenbee's main body is right on top of it, and she likes to hug the top of the arena and even when descending barely provides enough space to properly aim for her main body without a high risk of hitting the beehive. This makes the waiting game for an opening even more hectic than just recharging the Giga Crush since it comes with the high chance of failure and starting again. Though like Vulturon you're free to deal with her missiles and bee drones however you want.
• 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.
• Social Darwinist: She's completely on board with Albert's plan to reset the world to pave the way for the next step of evolution, and when defeated the second time expresses disgust at the idea of "colluding with the evolutionary inferior".
• 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. The Bronze and Gold Medals respectively are earned 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.
• 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:
  • Her Silver Medal is to defeat her by punching one of her mouse robots into her.
  • Her Bronze Medal has shades of this, as it requires you to defeat her with Chronoforce, which can only be done when she floods the room and allows him to move around freely to fire his ice arrows.
• Ignored Enemy: She believes Grey/Ashe are dismissing her and it riles her up to give them "a shocking penalty." In fairness, Ashe really is mocking her, while Grey just tells her bluntly to get out of his way.
• 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: Talks very quickly and tends to repeat her statements. It adds to her hyperactive and childish personality.
• Rolling Attack: Is very is fond of this and has two versions: one where she rolls with her spikes extended, and the other with her spikes retracted. As an A-Trans form, the latter 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."
• Elemental Rock-Paper-Scissors: His Bronze and Silver Medals are obtained by defeating him as either Queenbee or Buckfire respectively, those being the two fire-based Psuedoroids with a type advantage against him.
• 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.
• The Leader: According to Word of God, he's this for the ZXA Pseudoroids, which is fitting given his Undying Loyalty to Albert and that he guards the Bio Lab containing many of the Mechaniloids meant to serve the Mega Man King in purging the world of life.
• 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. His Secret Disk even notes he was designed for base defense (where speed would be unneeded since he was meant to hold a position in a presumably fortified area) rather than all-out offensive.
• Never Smile at a Crocodile: He's a giant robo-crocodile whose teeth can shatter the strongest blocks in the game and has a whole host of weaponry to murder with.
  "I shall crush every last one of your bones with my jaws!"
• 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: For all his offensive power, 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. Combined with his slow movement, he might be able to kill everything within reach with extreme prejudice, but enemies outside his range can easily take potshots at him and rack up damage as he tries to close the gap.
• 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, and they take their jobs as guards very seriously, to the point they don't wait to fight Grey/Ashe at the end of the stage, but the very start since they have no interest in letting them get close to the facility.
• Blown Across the Room: Most minor enemies hit by Ugoyle's kick are going to end up being launched across the screen if they aren't outright destroyed.
• 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.
• Half the Man He Used to Be: Their Gold Medal requires them to be defeated at the same time by Buckfire's Double Tomahawk, which will result in this on both of them at the same time if done correctly. If one dies slightly before the other, however, it's possible to see only one of them get sliced in half while the other remains intact but starts to turn gunmetal grey (and no, this doesn't count for the Medal in question).
• Hurricane Kick: Use Ugoyle's kick while jumping or falling through the air or while on a ladder, and he'll perform a mid-air rapid body-twisting kick. Keep holding it, and he'll keep spinning.
• 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, and is necessary to obtain collectibles behind otherwise impassable walls or barriers (most notably a Sub-Tank in Hedgeshock's stage).
• Kick Chick: Gender-inverted with Ugoyle, who's main offense is kicking targets and Argoyle's bombs, which makes them even stronger.
• 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.

Biometals

In General

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

• 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.
• Healing Factor: In ZX, Muguet notes that Biometal makes Vent/Aile more resistant to injury and allows them to heal their wounds faster. They even act as a life support system, which is presumably how Mega Men have no problem functioning underwater (and would likely also be able to resist being in outer space conditions), and is the only reason Giro didn't immediately die from his fatal injuries (though it was noted giving Model Z up would fix that quickly).
• Instant Armor: Undergoing a Megamerge with a Biometal gives the Chosen One a suit of armor based on the data of the person the Model is based on along with the corresponding abilities, and is the source of their power.
• Legacy Character: Except for Model A and Model a, each Biometal is either based on the data of an existing character from the X/Zero series or outright has their souls inside them.
• Lightning Bruiser: Every single Mega Man has strength, speed, and durability far above any normal Humanoid and Reploid (and as mentioned above in Vent/Aile, Ashe, and Grey's folders, those are already superhuman by real-life standards). Case in point, the series shows even a non-specialized Mega Man can comfortably navigate the bottom of the ocean around undersea volcanoes, can react to and dodge laser beams and lightning bolts, and tear through reinforced metal like tissue paper with their attacks.
• Only the Chosen May Wield:
  • 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, and this time he gets Double Charge Shot right out the gate.
• 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 wield.
• 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.
• 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.
• 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.
• 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).

---

• Bizarre and Improbable Ballistics: Model F's Buster Edit ability is used to change the trajectory of its normal shots. Model F's bullets can turn on a dime at 90 degree angles.
• Blood Knight: Even as a chunk of metal, Fafnir is shown to be very eager on fighting.
• Charged Attack: All of them can charge their attacks to deliver a powerful strike that consumes weapon energy. A second stage charge attack is unlocked after collecting the second fragment in the first game.
• Enemy-Detecting Radar: Model P's special lower-screen function is to locate enemies in the area. Can also help you see Invisible Monsters.
• Enemy Scan: Model H can scan the enemy's HP and, if it's a Pseudoroid, its weak point.
• Homing Projectile: Touching enemies on the bottom screen while using Model P throws a single kunai that is guaranteed to hit from any angle, if the enemy is not invulnerable.
• Innate Night Vision: Model P not only provides superior visual ability in the dark (shown by the much larger field of view in darkened areas compared to other transformations), but also comes equipped with Enemy-Detecting Radar.
• Intangible Man: Model P's Overdrive Mode ability, the Shadow Dash, enables phasing through enemies while dashing.
• Knight in Sour Armor: Model H muses that stopping Serpent will do nothing to stop the endless cycle of war humanity has been embroiled in for centuries, but still believes that their fight had meaning.
• Megaton Punch: Model F's busters can send the enemy off flying forward or shattering destructible walls. Noticeably, they're strong enough to shatter a wall of solid Ceratanium (the same material Rock's armor is made of).
• My Master, Right or Wrong: In ZX it's spelled out, in no uncertain terms, that none of the Biometals can defy the intentions of their masters and can conceivably be used for good or evil. This is hit home in Advent with the Four Guardian Models falling into the hands of the Enemy Mega Men. Model Z seems to somehow be able to suppress and pin down said Mega Men, though.
• Not Quite Flight: Model H can Air Dash sideways or upwards (Effectively a Double Jump), as well as slow his descent.
• Shaping Your Attacks: Model L's user can summon serpentine dragons made of ice that can home in on enemies.
• Spin Attack: While swimming underwater, Model L can rapidly twirl the halberd in a circular arc. While each hit is weaker than the usual single slice, it ignores Mercy Invincibility.
• Spread Shot: Mode L can create a small chunk of ice which, when struck, sprays ice shards.
• Super Mode: Overdrive Mode, only available in the first game. In exchange for using Weapon Energy, Models HX, FX, and LX imbud their normal attacks with their elemental affinities while Model PX gets a flat damage increase and the ability to use Shadow Dash.
• Sword Beam: Model H's laser blade combo (slashing sideways, downwards, then with both blades) creates a damaging blast of concentrated air and energy.
• Temporary Platform: Model L can create a chunk of ice that can float on water and move if struck. It will also do damage if it makes contact with an enemy, which can be achieved by summoning it while above an enemy while at a higher elevation or jumping to drop it on their heads or bait them into colliding into it.
• This Looks Like a Job for Aquaman: Model L isn't very useful outside of the water or fighting wind bosses, as while it can certainly fight it's limited by the fact its weapon is melee only and slow (albeit powerful) with no way to attack range-wise without using Weapon Energy.
• Throw Down the Bomblet: In the second game, Ashe's Model F Charge Attack either shoots a fiery bomb forward or plants it down as a mine.

Model A

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

The most mysterious of the Biometals and a central figure of ZX Advent.

---

• 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.

• 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.
• Deadpan Snarker: Several times when exasperated by Grey or Ashe's attitude. Particularly when he's trying to psyche up Grey to go against Albert by saying "and yeah, we can do heroic rescues along the way."
• Do Not Call Me "Paul": Model A has rejected his original name and only goes by its abbreviation.
  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.

• 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 Aile/Vent), 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 (Massive Spoilers)

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 as the Ouroboros 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. In Advent in particular, Grey's confrontation with Albert at the endgame implies most of Albert's megalomania is his own with him claiming he came to his conclusion with mankind's constant fighting, while Ashe's story implies Model W is definitely feeding his insanity with his rant about Model W's desire for destruction.
• 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 Zero series is DNA revival.
• The Corruption: This Biometal is the new 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.
• Creating Life: It has the ability to create Maverick Mechaniloids once sufficiently powered up. Albert goes so far as to claim the fully-realized Model W has the power "to control all life" and this ability is the core behind his Restart the World plot.
• 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 its ability to feed on the evil within its host to multiply and spread.
• Gravity Master: Implied to be one power in its possession, as the Floating Ruins in Advent were created by a Model W activating and ripping chunks of forest into the sky and suspending them there in a manner explicitly stated to be a "gravitational anomaly", not to mention how Prometheus and Pandora have natural floating capabilities as Model W Mega Men and Albert is able to fly upon using either the Model W fragments floating around him or freely move through the air in his proper Megamerged form. Plus, how else would the Ouroboros remain airborne?
• 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 its vicinity, which it then eats to grow stronger and continue the cycle.
• Hijacked by Ganon: Seeing as it's Dr. Weil, the Big Bad of the Zero 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.
• Omnicidal Maniac: Per the words of Albert himself in Ashe's storyline. Fitting, given Dr. Weil was very much this too.
  "Model W craves destruction. It desires that the Earth conclude its own autobiography. So be it! Model W... Ultimate Mega Man! If at evolution's extreme... there is destruction, it was destined to be that way."
• Ouroboros: All the fragmented Model Ws can merge to form a massive floating structure called this. The name and cycle imagery is intentional, as Albert intends to use it to Restart the World and birth new life onto the planet once the old has all been either eliminated or assimilated.
• 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 Six Pack: There are many pieces of Model W scattered throughout the ZX world.
• Super-Empowering: The Model W Core in the Quarry of Advent falls into the destroyed husk of a Spidrill and subsequently merges with it, not just repairing it but powering it up into the "Spidrill Neo" with a sick new purple paintjob and increased stats, especially durability.
• Super Prototype: It's the original Biometal, yet its powerset (as shown being wielded by Serpent, Prometheus, Pandora, the eight ZXA Pseudoroids, and Albert) is adaptive enough to surpass nearly all of its successor Models with even Model A being a noted back-up system and pale imitation by Albert himself. And that's not even factoring in the powerset of the Core forms, or even Ouroboros.
• Ultimate Life Form: The "Mega Man King" and wielder of the Ouroboros is referred to as the "Ultimate Mega Man" who has "evolved beyond the mere fusion of man and machine" with the power to control all life” according to Albert, meaning it's meant to be this, a god, and/or a level of Transhumanism that no one before has reached.
• 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 emotions of those who are consumed with fear or hate and against the Weak-Willed it will also devour their souls, as poor Gary the Raider learns to his regret.

Model O

Your reward for conquering ZX's Optional Bosses, Omega's final form, 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. Double Megamerges with Model X to play as a near-exact replica of Zero from his series. You can only receive Model O on a cleared save file.

---

• 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.

• 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 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: In Overdrive Mode, the user can punch the ground to create bursts of energy. One causes rocks to fly away from the user, damaging enemies if hit; another (done after half-charge) is stylized after X series Zero's Rakuhouha; and the last one (done after full-charge) takes cues from the Rekkoha.
• 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 He can't use his sword or buster attacks while dashing, and he can't use the charged saber with some original attacks from Omega Zero added, including the infamous double-charge buster + Sword Beam combo.
• Superpowered 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.
  • Within the ZX Advent manga, where Alie is shown to be using it, she doesn't appear to be fully in control over the form, which seems to suggest that this trope is the case when using this power.
• 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.
