    Playable Characters 

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

Vent voiced by: Sanae Kobayashi (ZX), Kenji Nojima (ZXA)
Aile voiced by: Sanae Kobayashi (ZX and ZXA)

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

Voiced by: Ami Koshimizu (JP)

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.

Voiced by: Hiromi Hirata (JP), Peter van Gomm (EN)


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 Protoman.

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.


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

Master Mikhail

The third member of the Sage Trinity. Seems to be the most venerable and down-to-earth member of the trio, given his shock and horror that Master Thomas plans to continue with Albert's work.

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

The Hunters

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


Prometheus & Pandora

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

Pandora voiced by: Shizuka Ito (JP), Rumiko Varnes (EN)

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

  • All There in the Manual: The ZX Gigamix album shows them without their armor on.
  • Aloof Older Siblings: They only care about themselves and each other, and have nothing but disdain for their "younger brother," Grey. And there's, you know, trying to kill him.
  • Attack Drone: Pandora has 2 drones attached to her hair that can be used to fire off elemental attacks.
  • Ax-Crazy: Prometheus.
  • Badass Adorable: Pandora, although her "adorable" overshadows the "badass," especially in comparison to Prometheus.
  • Blood Knight: Prometheus is quite nihilistic, enjoying nothing more than mindless violence and a good fight. However, this may have been deconstructed after your fight with them in ZX Advent; he hints that his having to do senseless fighting was one of the reasons as to why he and Pandora wanted to betray and kill Albert in the first place.
  • 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.
  • Chewing the Scenery: Prometheus chews enough scenery to make up for his sister's lack of it, especially near the end of Advent.
  • The Corrupter: According to others, Slither Inc. began to change the moment Prometheus and Pandora came onto the scene.
  • Dark and Troubled Past: From the game itself, it's implied that they've been suffering throughout their entire lives. If the drama tracks are anything to go by (see Flashback Nightmare below), it also shows them getting raided by Mavericks when they were younger.
  • Dark Magical Girl/Lady of Black Magic: Pandora. To a certain extent, anyway.
  • Emotionless Girl: Pandora. She's the exact opposite of her sibling, but no less dangerous or malicious.
  • Even Evil Has Loved Ones: For what it's worth, they do love each other immensely. This does not extend to their little "brother" Grey, however.
  • Evil Duo: They're a villainous Brother–Sister Team.
  • Evil Is Hammy: Prometheus all the way. Pandora is much more composed.
  • Evil Laugh: Prometheus gets an epic one in the Japanese version.
  • Expy: Pandora is possibly a subtle one to Shion Sonozaki. Both wear their hair in a similar fashion, have the same shade of green, prefer white and blue (the hue is different) and both are driven to madness as the result of a rather nasty past.
  • Fire/Ice/Lightning: They cover all three.
  • Flashback Nightmare: Prometheus gets what appears to be this in the drama tracks when he's being rejuvenated in his capsule.
  • Grim Reaper: Prometheus.
  • Half-Identical Twins: There's some semblance, but you'd be hard pressed to be believe they're actually siblings if you didn't already know. Justified in that that were both artificially made.
  • An Ice Person: Pandora.
  • 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.
  • Magic Wand/Simple Staff: Pandora.
  • Mysterious Waif: Pandora. A notable evil example.
  • People Jars: Each have one in the Mysterious Lab stage. It's used for daily maintenance, seeing as their days are numbered.
  • Playing with Fire: Prometheus, natch.
    • Flaming Skulls: One of his attacks in the first game summons four of these to the corner of the stages, and each of them will fire small fireballs at you. It's hard to dodge, but you can destroy the skulls, reducing the difficulty.
  • Power Floats: Pandora is almost always seen floating. Prometheus only floats when he uses area attacks.
  • Prehensile Hair: Prometheus. Yes, that's his hair he's using to attack you.
  • Psycho for Hire: Prometheus.
  • Psycho Prototypes: To Grey, although he was intended to become just like them.
  • Recurring Bosses: They're fought multiple times, both separately and together, in both games.
  • Purple Is Powerful: Prometheus wears purple armor and is most certainly one of the strongest Mega Men running around.
  • Rapunzel Hair: If the brief shot of them before being permanently bound to fragments of Model W is anything to go by. After the merger, Prometheus always has it, and uses it to kill you.
  • Red Baron: "The Reaper" or "Death" for Prometheus. Suffice to say, he lives up to that nickname. One of the Gigamix drama tracks even put a small emphasis on this.
    • Pandora gets the moniker of "The Witch." Her moments are fewer than those of her bro, but Pandora is just as much of a threat as Prometheus is.
  • Red Eyes, Take Warning: Ohhhhhh yes.
  • Red Oni, Blue Oni: The hammy, Ax-Crazy Prometheus is the red oni, and the stoic Pandora is the blue oni.
  • Scythe And Sorcerer: Prometheus is the scythe who prefers getting up close and personal, while Pandora is the sorceress who attacks with the elements from a distance.
  • Shapeshifter Mode Lock: They're permanently bound to Model W.
  • Shock and Awe: Pandora.
  • Sibling Yin-Yang: Prometheus is loud, boisterous, and all too willing to express his joy at fighting and killing. Pandora is quiet, talks very little, and prefers to go about fighting and killing in a calm manner.
  • Sinister Scythe: Prometheus.
  • The Starscream: They fully intended to destroy Albert when the time came. And they did... just not the one they expected.
    • The Dog Bites Back: Their motivations for wanting to destroy Albert were closer to this, as they had been abused and underwent constant suffering.
  • The Stoic: Pandora is soft-spoken and generally not open about her emotions.
  • Suicide by Cop/I Cannot Self-Terminate: Prometheus and Pandora's choice of words before fighting Gray/Ashe strongly implies that they want them to kill them in battle.
  • Theme Naming: Named after two of Saturn's moons, as well as two mythological Greek deities; Prometheus (the god who introduced man to fire) and Pandora (who opened up the quintessential Sealed Evil in a Can, allowing all of the repressed, negative emotions to plague mankind).
  • Those Two Bad Guys: Though far deadlier and seriously played than most examples.
  • Woman in White: Pandora. Well, white armor anyway.
  • Woobie, Destroyer of Worlds: Despite appearances, they spent a long time fuming at the fact that they were made to be slaves for Albert's Game of Destiny. Prometheus's Famous Lastwords, before he and Pandora are royally owned by Model W, were a long rant about how pointless Albert's goal was, and that he might as well destroy the whole world thanks to the pain of what he and his sister had to endure.
  • You Gotta Have Blue Hair: Prometheus has blue, Pandora has green.
  • Your Days Are Numbered: Wonder how in the hell Albert got these two to listen to his plans after torturing them for much of their youth? He intentionally made it so that, after he fused them with Model W, they would have an extremely short lifespan and would need regular maintenance to survive. Of course, they eventually decide they'd just kill everyone before dying themselves...
    • Stalked by the Bell: There is a literal counter on their capsules that is constantly ticking. If they're not back in the capsules by the time it's done...well...

The head of Slither Inc. in the first game. Was corrupted by Model W at some point before and sought to fully awaken its power. 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.

Voiced by: Kiyoyuki Yanada

  • Aile, "He" Is Your Ancestor: 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).
  • Animal Motifs: May be averted, despite having an animal name.
  • As Long as There is Evil: In his Final Speech, he proclaims that as long as people — humans and Reploids alike — have something called a "heart," hatred will always lurk within them, and that those who refuses the idea of change are the true Mavericks.
  • Attack Its Weakpoint: In his second form, depending on the phase, you have to attack different weak points. The first is his head, the second is his shoulders, the third is the crystal in the middle of his "lower face".
  • Badass Longcoat
  • Big Bad and Final Boss: Of ZX.
  • Corrupt Corporate Executive
  • 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.
  • Evil Redhead
  • Evilutionary Biologist: Albeit not to the scale of Albert.
  • Expy: His physical appearance and "evolutionary" sentiments are highly reminiscient of Sigma.
  • Final Boss Preview: He's first seen mind-controlling the injured Giro, and then he introduced himself after he strikes Giro down again (after you fight Giro as the boss).
  • Finger Gun: He can fire spreads of energy shots from his fingertips.
  • Freudian Excuse: Aile's story, as well as Aeolus' cipher in ZXA, suggest that the reason he ended up being affected by Model W is because he was a Maverick raid survivor, and that he was afraid of his past. Having a trace of Albert's blood sealed the deal, though.
  • Gemstone Assault: In his second form, he can create growing crystals and then smash it; its debris can damage you.
  • Giant Hands of Doom: He employs these in his second form's third phase. They can create damaging crystals or fire energy shots.
  • Ground Pound: His first form has a move where he teleports directly above you and then tries to smash you with his feet. In Hard mode, this move also fires off spreading energy shots.
  • Humans Are Bastards: He wholeheartedly believes that so long as humans hold emotions in their hearts, they're no different from the Mavericks, being just as destructive as they are.
    Serpent: "The destiny of destruction... Still awaits... So long as you have hearts, hate will lurk in the shadows. You who possess the wellspring of emotion known as the heart... You are the true Mavericks!"
  • It Is Pronounced Tro PAY: According to the Japanese spelling, he goes by the French pronunciation, "Sair-pahn."
  • Large and in Charge
  • Laughing Mad: His reaction as Model W's core is enveloping him into its system.
  • Life Drain: In his second form, where he fires 2 moving crosshairs that tracks your position; if you get hit, he'll extend an energy line that drains your health. Mash directional buttons to escape!
  • Lightning Bruiser: Serpent's first form on Hard mode is this Up to Eleven, and is among the most difficult boss fights in the whole franchise. Most of his attacks are sped way up or have extra range by extension, demanding sharp reflexes and careful positioning to avoid having your tiny lifebar shot to nothing. It's essential to memorize his attack pattern and where his blind spots are after attacking (and he'll probably be killing you enough times for you to find a rhythm). The trouble is, even after you get it down pat, the pressure is still on to not get hit because he's a Sequential Boss, and you're carrying any damage taken into the next round. Have fun.
  • Names to Run Away from Really Fast
  • One-Winged Angel: Yup, a final boss staple.
  • Painfully Slow Projectile: His first form has a move where he shoots a very slow-moving Energy Ball that can be repelled back at him by enough shots.
  • Sequential Boss: Continuing the tradition. In Round 1, he Megamerges with Model W in a traditional manner (akin to the protagonist's ability). You defeat him just in time for Model W's core to awaken for Round 2. Even in Round 2, he can expand his form 2 more times.
  • Shoryuken: One of his first form's moves.
  • Slide Attack: In his first form a-la Copy X (of Mega Man Zero).
  • The Social Darwinist: He even pulls out the iconic (and frequently misunderstood) "Survival of the fittest" line.
    • Well-Intentioned Extremist: He states that he wishes to evolve the world rather than destroy it. In addition, he tells Vent that he wishes to remove pain and suffering from the world. His methods for doing so? Model W.
  • Start of Darkness: Was a member of the Guardians... and then he encountered Model W, causing him to wipe out his entire group (minus the leader).
  • Straw Nihilist: After Vent/Aile beats him for the final time, Serpent tells him/her that his fight to protect the ones he/she loves is pointless, as life will just go on in the cycle of peace and war.
  • Strike Me Down with All of Your Hatred: Tricks Vent/Aile into doing this to complete Model W's awakening.
  • Super Mode: His first form also has the Overdrive Mode. He moves much faster in this mode.
  • Unwitting Pawn: Subverted. He appears to have known something about Albert and his plans, judging from taunting Aile that she has the blood of the man who made Model W.
  • Villain with Good Publicity
  • With Great Power Comes Great Insanity: Yup.
  • Woobie, Destroyer of Worlds: A large part of his character was from being an implied orphan from a Maverick attack, and it is strongly implied (although he denies it) that he suffered from intense fear from that past, evidentially leading to his insanity. In addition, in the Japanese version, when denying Vent's retorts to Serpent, Serpent sounded a bit melancholy.
  • You Killed My Father: Not directly, but it is implied that Serpent arranged for Vent and Aile's parents to be killed.
  • You Will Not Evade Me: His second form can create a black hole to pull you in (or alternately push you away).

Master Albert

Spoilers! Click here to see his true body 

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.

Voiced by: Yoshito Yasuhara (JP), Jack Merluzzi (EN)

  • Actually a Doombot: Prometheus kills Albert when he and Pandora show up in Albert's underwater base. Then after they fought Grey/Ashe, their emotions are suddenly sucked into the Model Ws in the background. Turns out, the Albert that Prometheus killed was a decoy.
  • Affably Evil: More so "affable" before The Reveal. Always evil.
  • 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, and Chronoforce's Time Bomb (although it's used only to counteract and nullify the player's own Time Bomb). His "bits" even glow with the appropriate color for each borrowed attack.
  • Attack Drone: Controls several bits in his Megamerged form, all of which are capable of emulating attacks from other Mega Men.
  • Badass Bookworm: Whereas Thomas and Mikhail are depicted as carrying a sword and a knife, Albert is usually seen holding a book.
  • Big Bad and Final Boss: For ZX Advent.
  • Bishonen Line: Goes from a three-headed mechanical dragon, to the vastly-powerful, nigh-angelic Mega Man Model W.
  • The Chooser of The One: More like The Chooser Of The Many, but he still qualifies.
  • 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.
  • 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.
  • Discontinuity Nod/Continuity Snarl: His origin story for Model A ("A" as in "Albert," not "Axl"), as well as whether or not Master Albert is controlling Model W or vice versa. These plot points (especially the former) have been eating at fans to this day, leading to a jungle of Epileptic Trees. For example, the fact that Albert clearly says "Axl Bullets" while firing his Homing Shots does not help. Doesn't look like any of this will be resolved, either.
  • Evil Counterpart/Mirror Boss: Could be considered one to Grey/Ashe, seeing as his abilities with Model W (see All Your Powers Combined above) are identical to those of Model A's, but stronger and more versatile. Justified in that Model A was created to mimic the power of Model W as a backup plan in case Albert was somehow incapacitated.
  • Evilutionary Biologist
    Albert: "I wanted to be the ultimate... To be at evolution's extreme... as one of the Sage Trinity, but above all, as a scientist. At evolution's extreme, there is emptiness and misery."
  • Expy: Officially of Dr. Albert Wily, although most of his personality and goals are more similar to those of Albert Wesker.
  • Eyes Always Shut: Until The Reveal, where it's revealed that his eyes are red with black sclera.
  • Face–Heel Turn: Subverted. He was actually researching on Model W since long before the events of the games, as Master Thomas explains.
  • The Faceless: As Mega Man Model W. All that you can see are his Glowing Eyes of Doom (well, at least until right near his death).
  • 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: "I don't think I'm a god. I AM A GOD!"
  • Ground Punch: In his second form he can form his bits into the shape of a fist, which he then brings down to the ground to create damaging flame pillars.
  • Hoist by His Own Petard: Whether it is by Grey or Ashe's hands, Albert is defeated by his own "backup plans" and Model A.
  • Idiot Hair: He sports one. His true form has a larger one.
  • Large Ham: Damn straight.
  • Luckily, My Shield Will Protect Me: Uses several Model W fragments to deflect Grey/Ashe's attacks during The Reveal. As Mega Man Model W, he is surrounded by several Model W-esque bits that must be destroyed before you can damage him. Said bits also double as his method of attack, including forming a BFS.
  • Luke, I Am Your Father: An interesting variation on this trope: Most of the Mega Men that are encountered, including the protagonists in the previous game, were able to Megamerge not only because they survived Maverick Raids, but because Albert altered their DNA with his genetic code, which allowed them to Megamerge. However, Ashe was the only one whose DNA can be traced to Albert that wasn't due to genetic tampering, meaning her familial relationship to Albert was legitimate. Played completely straight with Grey, however.
  • Mad Scientist: Shades of it.
  • The Man Behind the Man: It's implied that Albert (via Prometheus & Pandora and Model W) was manipulating Serpent.
    • Unwitting Pawn: It's also implied in Ashe's story that Albert may be manipulated by Model W, his "creation," no less.
  • My A-Trans Is Better Than Yours: Possesses the "real A-Trans", allowing Albert to be able to change himself into the forms of those whose souls and negative emotions were absorbed by Model W. In addition, he does not even need to transform to utilize said powers (see All Your Powers Combined above). As Albert explains himself, Model A's A-Trans is a pale imitation.
  • Name's the Same: Shares his first name with another Capcom Mad Scientist Magnificent Bastard who plans to use Ouroboros to reset the world and take his place as a god. Maybe Model W stands for Model Wesker?
  • 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.
  • 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.
  • People Jars: His original body (DAN-000) has one.
  • Pet the Dog: An extremely, extremely small one when he expresses sympathy and regret over having to do in Ashe.
  • Power Floats: In the cutscene of the reveal about him being the villain, he floats away using Model W. Later in Ouroboros, he slowly floats up as he transforms and the artificial sky breaks around him.
    • And during the battle with his Model W form, the only way to have Albert touch the ground is to forcibly introduce him to it.
  • Power Gives You Wings: As Mega Man Model W.
  • President Evil
  • Rapunzel Hair: In his true body, given that he's now only the size of Grey/Ashe, but retains his hair's length.
  • Restart the World: This is his motivation for using the Ouroboros, as he planned to destroy the world and then recreate it, with only leaving the Mega Men as the only ones worthy to live in his new world.
  • Sequential Boss: First his throne turns into a giant three-headed mechanical dragon armed to the teeth. When you smash that contraption, he just emerges from the rubble unscathed, continues his self-serving monologue, and Megamerges with Model W.
  • Shielded Core Boss: As Mega Man Model W. He has a forcefield which you need to destroy by damaging it enough; only then can you do damage to him. He does regenerate the forcefield after a short time, so give it all you've got once the forcefield is down.
  • Strike Me Down with All of Your Hatred: Yet again, this time done to Prometheus and Pandora. Their hundred years of pent-up hatred and suffering got used to activate lots of Model W fragments to form them to Ouroboros.
  • The Social Darwinist: Not to the extent of Serpent, but it's definitely there. Either that, or he's contemplating on whether or not he'll be a Straw Nihilist.
  • Teleport Spam
  • Tornado Move: He can create a pair of tornadoes in his battle form, taken from Model H's power.
  • Treacherous Advisor
  • 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.
  • Wave Motion Gun: As Mega Man Model W, he can fire two of these from the background to the left and right of the boss stage, and will slowly converge to the middle. You can try to jump at the right moment, or shoot one of the beams to push it back.
  • Well-Intentioned Extremist: His pre-final battle speech implies that the reason he decided to use Model W was because he wanted to stop people from fighting amongst themselves. The irony is positively ludicrous — how big is Advent's Gambit Pileup?
  • With My Hands Tied: His real body appears to be in a restraining jacket. It doesn't stop him from duping Prometheus and Pandora, though. He finally breaks out of it when he Megamerges.
  • You Gotta Have Blue Hair: Blue hair by default. When in his second, original body (DAN-000), it's freaking magenta.

Enemy Mega Men
Clockwise from top: Thetis, Atlas, Siarnaq, and Aeolus
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. They are:

  • Affably Evil: Thetis. He's a genuine Nice Guy, and the only one of the quartet who is actually friendly towards Grey/Ashe. If it wasn't for the extremes he went to accomplish his admirable goals, he'd probably be a straight-up hero.
  • Airplane Arms: Siarnaq's running and dashing animation, unlike the other Mega Men (who ironically use Ninja Run instead). Being Limp and Livid has something to do with this.
  • Ambiguously Human:
    • Both Aeolus and Atlas have hair obscuring their forehead, so we don't know if they have the red marks that confirm them as Reploids. At the very least, Atlas is implied to be human (as she's an orphan).
    • Thetis, on the other hand, does have a Reploid mark, yet Grey refers to him as human at one point. That said, given the context (where Thetis attacked a highway of innocents to feed the Model W fragment located there) Grey might have meant it in the context of "why would you kill fellow living people", which is reinforced by Thetis retorting that he and the others aren't humans, but Mega Men.
  • Ax-Crazy: Siarnaq has shades of this, mostly due to his bout of Laughing Mad as seen below.
  • The Beautiful Elite: Aeolus has shades of this, coupled with his Social Darwinistic tendencies.
  • Bizarre and Improbable Ballistics: Atlas can alter her projectile trajectories with her Buster Edit ability. The trajectory can be seen and predicted with red squares that appear on the screen.
  • Blade on a Stick: Thetis' weapon.
  • Blood Knight: Considering that her goal is to force evolution on mankind by starting a perpetual war, Atlas falls into this trope. No wonder she's paired up with Model F.
  • Blow You Away: Aeolus.
  • Boobs of Steel: Atlas' bust is noticeably bigger than the other females, and she's physically the strongest of the Mega Men.
  • Call-Back: Their attempt to gang up on Grey/Ashe right before the Final Boss almost exactly mirrors a scene from the original Mega Man Zero.
  • Ceiling Cling: Siarnaq is able to do this and Platform Cling.
  • Dark Action Girl: Atlas.
  • 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.
  • Doppelgänger Spin: Siarnaq.
  • Dual Wielding: Aeolus, with Laser Blades, mimicking Harpuia.
  • 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.
  • Expy: The entire group is this to X's Four Guardians. Explains why they're the Biomatches for each Guardian's Legacy Character.
  • The Faceless: Siarnaq while Megamerged. All that you see of him behind that faceguard and helmet are two glowing red eyes.
  • Fiery Redhead: Atlas. Both figuratively and literally (well, mostly).
  • Fingerless Gloves: All of them.
  • Five-Bad Band: With Master Albert as the Big Bad and Prometheus and Pandora as Co-Dragons respectively:
  • Flechette Storm: Siarnaq; not as the boss, but as the copied A-Trans form. One press of the attack button throws four kunai knives; Button Mashing it results in... You get the idea.
  • Fuuma Shuriken: Siarnaq's Charge Attack in Grey's storyline.
  • Gender-Blender Name: It doesn't matter what you say, Mega Man ZX, Thetis is still a girl's name, and Atlas is still a guy's name.
  • Granola Guy: Thetis.
  • Ground Pound: Atlas; in Grey's storyline, it results in a stream of fire, while in Ashe's storyline, it results in a fire bomb that acts as a mine. She also transforms this way.
  • Hand Cannons Akimbo: Atlas, via her Knuckle Busters Sodom and Gomorrah.
  • High-Altitude Battle: Aeolus's stage, a forest lifted up because of gravitational anomaly.
  • An Ice Person: Thetis.
  • Idiot Hair: Thetis.
  • I Need You Stronger: When Grey/Ashe meets Aeolus and Siarnaq in the Tower Of Verdure, Aeolus tells him/her to hone their skills before they can effectively fight, and then he and Siarnaq teleport out. It later bites him in the ass, resulting in This Cannot Be! below.
  • Just a Kid: How Atlas views Thetis. Thetis doesn't exactly take well to this and points out that she isn't that much older than him.
  • The Lad-ette: Atlas.
  • Laughing Mad: Siarnaq. And how! It's dialed back into a Evil Laugh in English.
  • Left for Dead: Siarnaq was backstabbed by his pals and left to rot. It's the reason behind his extreme stoicism, lack of trust, and dislike of all relationships in general.
  • Limp and Livid: Siarnaq as Mega Man Model P.
  • Meaningful Name: With the exception of Siarnaq (who is named after a giant from Inuit mythology), all of their names are the names of Greek Deities that correspond to the element they use. Atlas is commonly depicted holding up the globe, and thus controls earth and fire. Thetis is a sea goddess and mother of Achilles. Aeolus is the god of the winds.
  • Megaton Punch/Punched Across the Room: Atlas has an appropriately-named "Megaton Crush," the half-Charged Attack of her Hand Cannon which can send enemies flying forward, possibly hitting another enemy on the way for an extra kill count, hence the name Knuckle Busters.
  • Ninja: Siarnaq.
  • Not Themselves: It's implied that the Biometals stolen from Vent and Aile have somehow been bent to the will of their Biomatches. Given that all four Biometals are inexplicably The Voiceless in ZX Advent, it's truly unknown at this point. Additionally, this is taken to a literal degree, as the Megamerges look different from their ZX versions (especially in the case of Siarnaq and Model P), most likely due to the absence of Model X. Gameplay-wise, they function the same, with the moveset of each Biometal usually split between Grey and Ashe.
    • It's also implied that the enemy Mega Men themselves are either being influenced or are outright brainwashed due to their red eyes, which, as seen in the case of Serpent and (briefly) Giro in the first game, may imply that Model W has some sort of hold over them.
  • Nothing Is Scarier: Siarnaq doesn't seem to have any motive at all for participating in the Game of Destiny. It only makes his robotic disposition and shadow powers even creepier.
  • Peek-a-Bangs: Aeolus.
  • Platform Battle: Thetis's boss battle. You're restricted to 3 small rock platforms over a Bottomless Pit. Using Chronoforce form may ease things a bit, though, since said form can swim.
  • Playing with Fire: Atlas.
  • Power Gives You Wings: Aeolus, technically, since he acquires Model H.
  • Pride: Aeolus, and how.
  • Professional Killer: According to his data disk, Siarnaq was an assassin at some point in the past.
  • Quirky Miniboss Squad
  • Redemption Demotion: Expect Grey and Ashe's A-Trans versions of these four to be much less impressive than the real deal.
  • 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.
  • Shifting Sand Land: Atlas' stage, with additional crude oil mine and Raiders' crashed airship.
  • Shock and Awe: Again, Aeolus.
  • Smug Snake: Aeolus, all the way.
  • The Social Darwinist: Aeolus and Atlas, albeit in different ways.
  • The Stoic: Aeolus and Siarnaq. The latter is notable in that he's refined it into Robo Speak.
  • Sword Beam: Aeolus fires them in a style like Harpuia, but he (fortunately) cannot spam them.
  • Talking to Himself: In English, Siarnaq is voiced by Jamie West, who also voices Model Z.
  • Teleport Spam: Siarnaq.
  • Theme Naming: Like Prometheus and Pandora, Aeolus (Helios), Atlas, Thetis (Tethys), and Siarnaq were all supposed to be named after Saturnian moons. note  Additionally, Aeolus, Helios, Atlas, Thetis, and Tethys are figures from Greek mythology (a majority of them being Titans) whose powers and backstories correlate to the Elemental Powers of the quartet. In this regard, Siarnaq is the odd man out; his only mythological counterpart is a mythical Inuit mermaid patron of seals.
  • This Cannot Be!: The insufferably arrogant Aeolus cannot believe that he was bested by an inferior Mega Man like Grey or Ashe.
  • Tomboyish Name: Atlas. Inverted with Thetis.
  • Underwater Boss Battle: Thetis, of course.
  • Villain Forgot to Level Grind: Presumably. They certainly didn't expect Grey/Ashe (relative newcomers to The Game of Destiny) to become more adept at using Model A in such a short time, to say the very least.
    • At least they were savvy enough to gang up on Grey/Ashe in the last level right before the Final Boss. Unfortunately, that's when Aile/Vent shows up to hold them off.
  • Well-Intentioned Extremist: Thetis and Atlas, especially Thetis. Atlas, as said above, wants humanity to become stronger, while Thetis wants to protect his beloved ocean from the progress of man. However, Atlas believes that humans can only evolve via suffering, and the ocean's safeguarding is very Serious Business to Thetis. Given that they're using Model W to accomplish said goals, their once-noble goals are taken to extremes.
  • Who Wants to Live Forever?: It is strongly implied that the four Mega Men's survival had to do with their having the Reploid Immortality data in the Hard mode Stinger, though Thomas' line about human bodies might imply that if any of the enemy Mega Men were humans, they'd be using a Body Backup Drive like Master Albert did.
  • You Don't Look Like You: In an odd way: Their Megamerged forms, being from a single Biometal (instead of a merge with Model X from the first game), doesn't match the forms of the Guardians themselves, except for Atlas' note  (although the same can be said for Girouette's form of Model Z). Some have theorized that it's because of the darker nature of the Enemy Mega Men's personalities, while some others theorized that the design evolved from their clothes note .
  • You Fool!: Aeolus is quite fond of this phrase.
  • You Gotta Have Blue Hair: Thetis with blue hair, Aeolus with bright green, and Siarnaq with dark purple.
  • Zettai Ryouiki: Thetis, a rare male example. Grade A/B.

    ZX Pseudoroids 

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

    ZXA Pseudoroids

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

  • 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 (but also another one on his head), and have we already said that he is a rose? Is there any other way to take that?
  • Animal Motifs:
  • Arm Cannon: Buckfire has 2 of 'em.
  • 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.
  • Ax-Crazy: Queenbee really craves for destruction and terror. Vulturon is similarly unhinged.
  • Beware My Stinger Tail: Queenbee, of course. Though she never stings you with it, instead she fires fire blasts from it.
  • Boomerang Comeback: Buckfire can use the blades around his harms as these.
  • Braids, Beads and Buckskins: Buckfire has a Native American motif.
  • Combination Attack: Argoyle and Ugoyle is fond of these.
    • As the playable version, you can have Argoyle throws a ball and then have Ugoyle's ghost kick it in order to power it up.
  • Dash Attack: Buckfire has one (see Horn Attack below).
  • Deadly Disc: Bifrost can fire spiky wheels of doom.
  • Doppelgänger Attack: You can only control Argoyle after you defeat the twins, but you can summon Ugoyle's ghost as a special move.
  • Diving Kick: Buckfire has a potent one that can break weak walls.
  • Do Not Run with a Gun: Many of their copied forms prohibited you from shooting while running.
  • Dual Boss: Argoyle and Ugoyle.
  • Dub Name Change: 5 of the 8 were named differently in Japan.
  • Expy: Buckfire, Queenbee and Bifrost are ones to Flame Stag, Wheel Gator and Blast Hornet.
    • Vulturon: Zombielike? Check. Uses a guitar? Check. Has a crazy rocker personality? Check. He must've been taking some notes from Lord Raptor.
    • Hedgeshock can be one to Sonic the Hedgehog and Pikachu.
  • The Fighting Narcissist: Vulturon always wants his fights to be "rocking".
  • Fire/Ice/Lightning
  • Flunky Boss:
    • Chronoforce can summon miniatures of himself from his shell.
    • Vulturon can use his guitar-shaped device to animate pieces of junk.
    • Hedgeshock can summon some mouse flunkies.
    • Queenbee has a Bee Bee Gun variant.
  • Fragile Speedster: Hedgeshock doesn't have much in terms of defense, but she's very fast.
  • Frickin' Laser Beams: Queenbee as a boss can fire many lasers from her beehive (think of a disco ball). She can also fire a strong laser downward that causes burning rubble to pop outward.
  • Goomba Stomp: Bifrost can do this to smaller enemies. Well, he's frickin' huge.
  • 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".
  • Horn Attack: Buckfire can either dash with his horn pointed forward, or do a Shoryuken with his horn. The latter can break weak walls.
  • Hulk Speak: Buckfire speaks this way.
  • Knight Templar: Buckfire values order above all else.
  • Lethal Joke Character: Chronoforce, as you take its form; it can't move at all on land, but is immune to attacks from attacks from above and its charge shot, the Time Bomb, is very useful. You can even change form after it's activated.
  • Locomotive Level/Traintop Battle: Buckfire's stage.
  • 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.
    • Bifrost can defend himself by opening his large jaw.
  • Macross Missile Massacre: Queenbee as a boss can fire these out of her beehive.
  • Metal Head: Vulturon, fitting his theme, likes head-banging. It also helps that he's voiced by Kishō Taniyama.
  • Mighty Glacier: Bifrost — he has a great attack power, but he moves very slowly. Bonus point of being An Ice Person, fulfilling every sense of the trope name.
  • Motor Mouth: Hedgeshock talks very quickly.
  • 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.
  • Not Completely Useless/Crippling Overspecialization: You either use them when you're just having fun or when you need to solve puzzles. The Mega Man forms are much faster than any of them, that's why.
    • Except Buckfire, whose speed and higher jumps makes him a comfortable method of getting from Point A to Point B when you didn't unlock enough beacons. The fact that you can spam his three-directional shots that ALSO do Damage Over Time to virtually all enemies and bosses in the game also makes him a good choice for some boss battles, most notably Queenbee. His only real weakness is his gigantic hitbox.
  • Now, That's Using Your Teeth!: Bifrost's large jaws and strong teeth leads to this.
  • Plant Person/Something About a Rose: Rospark.
  • Rollerblade Good: Argoyle and Ugoyle's feet are fitted with wheels.
  • Rolling Attack: Hedgeshock is fond of this.
  • 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.
  • 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 Angyo and Ungyo.
  • Spike Shooter: Chronoforce and Bifrost can shoot icicles, while Rospark can shoot rose thorns.
  • Spread Shot: Quite a few. Buckfire's flaming arrows and Hedgeshock's Charged Attack sparks are of the regular variety, while Rospark's thorns is Spray Bursts.
    • Chronoforce's boss only move has him shooting a spread of icicles.
  • Spring Shoes: Buckfire's upwards horn attack can be used as this.
  • Stance System: Rospark has 2 forms: bulb form and flower form, the latter accessible by climbing ropes.
  • Tail Slap: Bifrost can whack enemies with his tail as he switches direction.
  • 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 icicle flying back at him.
  • Wave-Motion Tuning Fork: Rospark can use the rods on his head and crotch to fire off an electric laser.
  • Whip It Good: Rospark can weaponize his thorny vines like this. He can even electrify it.

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

Model X

I am the light that illuminates all possibilities, Lumine Infinitus...

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 its 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 its own; this triggered their first Double Megamerge with Model Z (courtesy of Giro dying and giving said model to Vent/Aile). They're still in Vent/Aile's possession as he/she appears in the second game.

  • Charged Attack
  • 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: Just as always.
    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: Its Double Megamerge feature assimilates the other Biometal's power for the Model X's user to use.

Model Z

I am the courage that fights for beliefs, Fortitude Creed...

Girouette is its 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.

  • 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
  • It Was a Gift/Memento MacGuffin: How Vent/Aile refers to it in the second game.
  • Laser Blade
  • Power Makes Your Hair Grow: As Double Megamerge with Model X, Model Z somehow can provide this.
  • Red Is Heroic
  • Shoryuken + Sword Beam: A new technique for Vent in the second game.
  • Sword Plant: A new technique for Aile in the second game.
  • 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 singlehandedly hold the Enemy Mega Men off, allowing the protagonists to escape while he goes down with Ouroboros.

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

Model A

The most mysterious of the Biometals and a central figure of ZX Advent. He seems to be based on Axl, but given the lack of proper conclusion to the X series and Master Albert having something to say about what that "A" stands for, who knows.

Voiced by: Yuu Kobayashi

  • 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.
  • Bratty Half-Pint: Hard not to figure Model A as one of these, just listening to him yap.
  • Chain Lightning/Roboteching: Their Homing Shot; the former in Ashe's storyline and the latter in Grey's.
  • Charged Attack
  • Crossdressing Voices: Model A identifies itself as a "he", but is voiced by a woman in both Japanese and English.
  • Embarrassing First Name/Do Not Call Me "Paul":
    Albert: A backup system that contains my plan and my knowledge. Model A... In other words, Model Albert.
    Model A: I hate that name!
  • Gradual Regeneration: Its weapon energy slowly regenerates over time, unlike in previous series.
  • Guns Akimbo: Subverted. Grey and Ashe are shown doing this in their promo art when Megamerged, but in-game Model A gives no such ability. Except in their Giga Crush, that is.
  • Laser-Guided Amnesia: At the start of the series, he doesn't know who built him or what he's built for.
  • Limit Break/Smart Bomb: Their Giga Crush ability.
  • Neuro-Vault: In the form of ciphers that are unlocked whenever Model A copies another Mega Man's DNA. Unlocking each of them reveals the one behind the whole mess and his intentions.
  • Power Copying/Voluntary Shapeshifting: Its A-Trans ability works this way.
  • Reflecting Laser: Ashe's charged shot.
  • Secret Keeper: After they collected the last cypher (from Vent/Aile), he remembers his purpose (that is, as a backup should Albert somehow fail), and considers it for the best that he doesn't tell Grey/Ashe about it until they're ready. Albert ends up doing it first, though.
  • Smart Bomb: Its Giga Crush attack lets the user shoot everything around them.

Model W

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

  • All Your Powers Combined: Albert's Model W exhibits the powers of all of the biometals.
  • Artifact of Doom
  • Back from the Dead: The souls of the ZXA Pseudoroids are bound to the Model W, and thus, it can resurrect them via the "True A-Trans". Fitting, given Dr. Weil's specialty in the MMZ series is DNA revival.
  • 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...)
  • Greater-Scope Villain
  • Hate Plague: The thing causes hatred and other negative feelings to appear within people in vicinity.
  • Hijacked by Ganon: Seeing as it's Dr. Weil, the Big Bad of the previous series, and it's ultimately the driving force of both games so far.
  • Light Is Not Good: Mainly colored gold and white, and, in case of Albert, looking like a seraphic angel when he transforms. Unquestionably evil, given its origins.
  • Mechanical Abomination: The core. Even if it is an immobile twisted-up chunk of metal, it looks as if it wants to gnaw your face off. The other cores in Advent don't all look quite as sickening... But wait until you see the Ouroboros.
  • Ouroboros: All the fragmented Model Ws can merge to form a massive floating structure called this.
  • The Plan: Implied; Model W is most likely keeping the Gambit Roulettes of all the other major players in the story spinning away, waiting for somebody or something to fully resurrect it.
  • Plot Hole: Are the Model Ws fragments of Ragnarok? Did Albert actually make them all instead? Or both? And where did the handheld Model Ws come from? Advent isn't very clear about any of these things...
  • 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.
  • Sealed Evil in a Can: Many, many, many cans.
  • Womb Level: The second half of Ouroboros runs with this theme, what with the giant beating heart-like mechanism looming in the background. After Albert dies, it promptly stops and turns the entire interior of the place a dull gray.
  • Your Soul Is Mine: It eats the souls of those who are consumed with fear or hate, as Prometheus and Pandora learn too late.

Model O

Your reward for conquering ZX's Bonus Boss, Omega's final form as Zero's original body. No small task, as he is no longer a pushover by any stretch of the imagination. Double Megamerges with Model X to play as a near-exact replica of Zero from his series and break what's left of the game over your knee. (Which isn't much — you can only receive Model O on a cleared save file.) Like the boss you get it from, it's a non-canon fanservice extra.
  • 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 Mega Man X6 Zero's Rekkoha). Thing is, it doesn't do that much damage and the user is vulnerable and can't move for a few seconds after it's launched.
  • Bragging Rights Reward: One that packs a hell of a punch, though.
  • Endgame+: Only in Normal or Hard difficulty.
  • Fire/Ice/Lightning: its Overdrive Mode lets it access all three kinds of elemental attacks: a fiery Shoryuken, a midair rolling slash that shoots ice shots all around the user, and an electric Sword Beam.
  • Ground Punch: 3 of its attacks in Overdrive Mode are this, where the user punches the ground to create bursts of energy. One causes rocks to fly away from the user, damaging enemies if hit; the other (done after half-charge) is stylized after X series Zero's Rakuhouha; while the last one (done after full-charge) takes cues from the Rekkoha.
  • Infinity+1 Biometal: And Purposely Overpowered.
  • Palette Swap: Recycles Zero's sprites with Omega Zero's palette and buster shot sprites.
  • Previous Player-Character Cameo: Controls identically to Zero series Zero, right down to the extra range on his saber slashes (Model ZX has a shorter reach), plus ZX's highly spammable spinning slash, just to be sure it makes ZX obsolete altogether.
  • Super Mode: It has an Overdrive mode like the Four Guardians, which never runs out, and augments all of his attacks, as well as somewhat changing its playstyle into X series Zero note  with some original attacks from Omega Zero added, including the infamous double-charge buster + Sword Beam combo.
  • Super-Powered Evil Side: In the official artwork Vent is laughing maniacally while Aile has a Psychotic Smirk, although gameplay-wise it simply serves as a more powerful alternate to Model ZX.
  • Sword and Gun: Just like Model ZX, Model OX is armed with a gun and sword.
