Playable Characters (in order of appearance)
Voiced by Ai Maeda in Japanese and Lia Sargent (Episode I & III), Olivia Hack (Episode II), and Stephanie Wittels (anime) in English.
Shion is the iron-willed but fairly ditzy head of Vector Industries First R&D Division's KOS-MOS project. She is the character around whom most of the events of the games revolve. She is (arguably) the central protagonist of the series.
- Action Girl: Shion is described as a very competent martial artist, though this really only shines in episode three. Put her in a AWGS, however, and she kicks all kind of ass regardless.
- Badass Normal: She's the only vanilla human in the first game's party. She quickly crosses over into Badass Abnormal though.
- Bunny Ears Lawyer: Shion seems to be a pretty competent scientist when not needlessly risking her own life or forgetting important documents.
- Cosmic Keystone: She has it for the entire series without ever knowing it.
- Deus Angst Machina: So very, very much. See the trope page for the full story.
- Custom Uniform: Shion's Vector uniform has blue highlights, unlike the green or red uniforms everyone else wears. Justified in that Kevin also wore a blue uniform, suggesting that blue denotes the project chief while everyone else in red and green are just regular members of the dev team.
- Fear of Thunder: Understandable, since her nanny, parents, and lover were all brutally killed in front of her during two different thunderstorms.
- Heroic BSOD: After finding out she's the one who called the Gnosis into the real number domain and summoned Abel's Arc.
- Hot Scientist: Ironically, her attractiveness increases the further she drifts from her job, going from an awkward and nerdy woman who's shackled to her job in Episode I to a veritable (unemployed) fashion model in Episode III. Unfortunately, her mental faculties seem to regress somewhat to make up for it...
- Improbable Age: She's the head of an extremely prestigious and cutting-edge research group belonging to the largest company in the galaxy while in her early twenties. And the average lifespan of humans in this universe is in hundreds of years. Probably justified in that Wilhelm needed her close so that he could keep track of her and make sure that she was in the right spot at the right time.
- Inner Monologue: Shion does this every once in a while.
- It's All About Me: Episode III
- Magitek: Shion's special attacks apparently use an "Ether Circuit."
- Meganekko: For the first game only. Sadly, she explains that she has perfect eyesight, and only uses the glasses to collect and analyze visual data in Episode III.
- Mini-Dress of Power: Her Vector uniform in Episode I. It returns as an alternate outfit in III.
- Pals with Jesus: Shion, in a past life, was called the Maiden of Mary. It seems that she and Mary Magdalene (yes, that Mary Magdalene) were very close.
- Oblivious to Love: Allen tries to ask Shion out and/or just get across that he loves her several times in the series and she just doesn't get it. He finally gets the girl, only because he decided to stand up to Kevin to win her back from him. To think what would have happened if that never occured.
- Pretty in Mink: Her jacket in III has a fur collar.
- Red Oni, Blue Oni: Red to Jin's and KOS-MOS' blue.
- Stripperific: Her outfit in Episode III (above), although her outfits in I and II weren't exactly conservative either.
- Swiss Army Weapon: Shion's M.W.S. It's nerfed into a standoff weapon in Episode II, but is rebuffed in Episode III'
- Tomato in the Mirror: She made contact with the Zohar and summoned the Gnosis.
- Trademark Favorite Food: Curry. It's her specialty dish to make.
- Tsundere: Particularly to her brother Jin, but also to just about everyone in her life other than KOS-MOS.
- TV Genius: The alleged robotics genius, is thicker than a brick on an interpersonal level and says and does a lot of really dumb things throughout all three games. Most obvious in the third game.
- Zettai Ryouiki: Episode III only.
KOS-MOS is an android built by Shion and Kevin Winicott in order to battle and destroy the Gnosis threat. She can use UMN transport to manifest absurdly powerful weapons. She is capable of generating the Hilbert effect (which draws Gnosis into Real space so they can be fought) at a range wider than even 100-series Realians can do with an amplifier. Her inner workings are described as a black box, and she sometimes acts in ways that go outside her programming.
- Action Girl
- Anthropomorphic Personification: Of the power of Animus, which controls the power of Anima and the relics of God.
- Arm Cannon: Her R-Cannon special attack.
- Artificial Human
- Become a Real Boy
- Boobs of Steel: She's the strongest female party member by far, and often the strongest party member, period. She's also the most built.
- BFG: Many of her special attacks, including shoulder mounted rail guns.
- Black Box: Her internal functions are even described by the characters as a black box.
- Chest Blaster: Her X-BUSTER located at the belly-region and (Form 4) D-TENERITAS is fired from just above her chest.
- Emotionless Girl
- Fun with Acronyms: Her name is a recursive acronym meaning Kosmos Obey Strategic Multiple Operation Systems.
- Gatling Good / Guns Akimbo: Subverted, it is one of her weakest special weapons. However, they're her most iconic weapons.
- Heroic Sacrifice: Repeatedly, thanks to her Made of Iron mechanical construction and the skill of Shion, the Professor, and other engineers.
- Hyperspace Arsenal: Justified since she uses UMN transport to access her arsenal, most of which is ridiculously huge.
- Mecha Expansion Pack: The Third Armament equipment.
- Red Oni, Blue Oni: Blue to Shion's red.
- Robot Girl: One of the most iconic robot girls in video games.
- Sinister Scythe: Her ultimate weapon in Episode I.
- Small Girl, Big Gun
- Sealed Inside a Person-Shaped Can: The conscience of Mary Magdelene is stored within KOS-MOS and is used to oppose the power of Anima (should anything bad happen) whom is chaos.
- Soul Jar: To T-Elos, to a degree. KOS-MOS' body was supposed to only be a temporary container of the Soul of Mary Magdalene, which was meant to be eventually absorbed by T-Elos.
- Stripperific A constant across all her various bodies and outfits... and apparently in direct proportion to Shion's role in designing them.
- Swiss Army Weapon: KOS-MOS herself. Specifically her arms.
- White-Haired Pretty Girl: Her very light blue hair in Episode I and III definitely evokes the spirit of this trope. Not so much when it is darker blue in Episode II.
- You Gotta Have Blue Hair
- Zettai Ryouiki: All of her costumes except her optional swimsuit.
Chaos is a very mysterious young man working aboard the tramp freighter Elsa. He seems to have connections to Jr. and Jin that date back decades. He also has some sort of connection to KOS-MOS as well as the Testaments and Wilhelm. He can destroy Gnosis with a touch.
- Anthropomorphic Personification: Of the power of Anima, a failsafe built into the Universe to destroy the "lower number domain" (the "real" universe) if the dispersal of consciousness ever threatened to destroy the "upper number domain." Naturally, chaos doesn't really want to do that.
- Bare-Fisted Monk: More apparent in the third game. In the first two, his fighting style is more like Full-Contact Magic.
- Beware the Nice Ones: The nice guy of the series. Also the one with the power to destroy Gnosis with a touch. And is an immortal, and implied to be the one behind Jesus' miracles. Oh, and he's the harbringer of the Apocalypse, if it ever comes to that.
- Blessed with Suck: His power of Anima is to ensure that the dissipation of the Collective Unconscious doesn't engulf both the Upper and Lower Domain and destroy the universe. While this sounds all well and good, the alternative is that his power actually Only contains the dissipation inside the Lower Domain, that is, the world the characters live in and the world where the Collective Unconscious reside, meaning, the Lower Domain is sacrificed to save the Upper Domain.
- Deuteragonist: Debatably
- Enigmatic Minion: A protagonistic example. Just look at all the spoilers here...
- Feather Motif: In this case, the feathers hint at a connection to the divine/angels.
- God Was My Co-Pilot: See Anthropomorphic Personification
- Heroic Neutral: He acts like a Badass Bystander during the majority of the plot (with only a declaration of...something at the end of Episode 2) and only reveals his full power at the end.
- Kung Fu Jesus: This is almost as literal a case you can get. He fights with his fists and was the Man Behind the Man to Jesus. i.e. chaos did Jesus' miracles while Jesus got the credit. Also, Wilhelm once called chaos "Yeshua," a name which, in some circles, is synonymous with Jesus.
- The Man Behind the Man: Inverted: Chaos is supposedly the man who worked the miracles for "The Messiah" (read: Jesus) while said Messiah was the public figure who everyone thought was doing them. Not really all that evil.
- The Messiah: Fits personality-wise.
- Nice Guy
- Really Seven Hundred Years Old: Or Time Abyss. He's been around since Jesus, making him at least 7000 years old. (Xenosaga taking place almost 5000 years after present day.)
- Red Oni, Blue Oni: Blue to Jr.'s red.
- The Stoic: He doesn't emote much. It's especially jarring when KOS-MOS awakens as Mary and he...just...stands there. And he's supposed to be Mary's soulmate.
- Too Many Belts: His costume in Epsiodes II and III.
- White-Haired Pretty Boy
- Darkskinned Blonde: Well, white hair, but the principle is the same.
Ziggurat 8, dubbed "Ziggy" by MOMO, was a police man named Jan Sauer in life. He committed suicide after losing his wife and child and was resurrected as a cyborg. He was hired to rescue MOMO from the U-TIC organization. He seeks to have all the organic parts of his brain replaced with machines so he can finally die. Eventually becomes a father figure to MOMO.
- BFG: All of his special weapons.
- Cyborg: He is one, but is considered obsolete by the time the series starts. Doesn't stop him from kicking ass all over the place.
- Expy: Ziggy has a great deal in common with RoboCop, from the Robo Cam to denying his previous identity until after some Character Development, and also looks more than a bit like Rutger Hauer as Roy Batty.
- Hammerspace: Presumably he uses UMN transport for his BFGs, just like KOS-MOS.
- Not So Stoic: After he sees Voyager in Episode II, we get to see him get pissed. Which leads to...
- Hypocritical Humor: Invoked by Jr. Ziggy spends a lot of time lecturing Jr to never let his emotions get the better of him during a high stress situation.
- No Celebrities Were Harmed: His looks and attitude were based on David Bowie and his persona Ziggy Stardust.
- Really Seven Hundred Years Old: He is frozen at the age of his death, which is his early thirties. However, he is about 130 years old.
- Swiss Army Weapon: Ziggy himself.
- Take a Third Option: At the end of Pied Piper, Voyager offers Jan the choice of becoming a Testament like him, or being absorbed into his consciousness like all his other victims. Jan puts his service pistol to his head and blows his brains out.
- To Become Human: Inverted. Ziggy is a human who wants to become a machine.
- Eventually subverted. He stops his mechanizing after some Character Development from meeting MOMO and finding out Voyager is alive.
- We Can Rebuild Him: Not that he wanted to be rebuilt...
MOMO is the prototype 100-series Realian (a type of organic android) who is widely sought after for the data her "father," Joachim Mizrahi, left inside her. She regards council member Juli Mizrahi as her mother and is visibly distressed when her mother doesn't want anything to do with her. She has the appearance of a 12-year-old girl.
- Age-Inappropriate Dress: Her Episode I outfit is prone to giving the viewer many a Panty Shot and she's twelve. She may be a Realian, but still.
- Apologetic Attacker: Episode I only. "I'm sorry, are you okay?" is one of her standard battle ending phrases.
- The Archer: In Episode II and III
- Artificial Human
- Cherry Blossom Girl: She's based on Sakura Mizrahi, who is strongly associated with Death (since she was a terminally Ill Girl and Posthumous Character) and who was Jr.'s first love interest. MOMO's pink hair and status as a White Magician Girl (at least in the first two games) seems to be a reference to this trope.
- Daddy's Girl: MOMO is really fond of her father, from what she can remember of him. She doesn't believe the rumors of his insanity when they pop up, even when they're seen as the common opinion. It is believed (even by her sisters) that she was Joachim's favorite.
- Drives Like Crazy: During Episode II's Chase Scene. Justified in that she was driving away from people who were trying to capture her.
- Fun with Acronyms: Her name means 'Multiple Observative Mimetic Organicus'.
- Magical Girl: In Episode I, MOMO has in-battle Transformation Sequences that give her special abilities. Seriously. Her name is also a Shout-Out to a classic magical girl, Minky Momo.
- Magic Knight: Due to gameplay mechanics in Episode III, she can be the best at dealing the most single target physical damage of all playable characters, even if her actual strength is actually dishing magical attacks and heals. Of course, she's not able to take damage as well as other characters, and takes certain gearing to bring her to average defensive wise.
- The Medic
- Mind Rape: By Albedo. Went to absurd lengths to try to remove the "mind" part.
- Muscles Are Meaningless: One of her techs in Xenosaga III is her own version of Ziggy's basic attack, Sword Fish, identical in animation and name. Since it does more damage and includes a heavy breaking effect, this pretty much reveals that MOMO punches harder than Ziggy. Mull that one over. Possibly justified by her being a super-advanced Realian.
- Panty Shot: Disturbingly often in episode one.
- Replacement Goldfish: To Ziggy for his dead child, presumably to Joachim for his daughter Sakura, and possibly to Jr. for Sakura.
- Joachim and, eventually, Juli come to see her as a second daughter than a Replacement Goldfish for Sakura. It's even mentioned that their personalities are very different.
- Robot Kid: Though not technically a robot.
- The Straight and Arrow Path: Since her bow channels Ether energy, and she is an ether attacker in almost all of her skill paths, the bow actually is a better choice for a weapon than a more "modern" weapon, at least in game logic.
- To Become Human: Dr. Mizrahi told her that if she did many good deeds, she'd become a real person.
- Indeed, she gets closer than most after the end of Episode III - the Encyclopedia mentions that she gained an upgrade that would allow her to carry a child.
- Token Loli: Yes, she is.
- White Magician Girl: Fits to a T in the first game, being primarily a support character, very feminine, a Mysterious Waif, and wielding a rod. Her skillset is player defined in the second, and in the third, you can choose to make her a Black Mage or a break attacker.
- You Gotta Have Pink Hair
- Zettai Ryouiki: Episode I and II. We can only conclude that the character designer likes this trope.
A gung-ho young man who commands the starship Durandal. He is second in command of the powerful Kukai Foundation, although his exact relationship to the owner, Gaignun, is the matter of some speculation. His weapon of choice is antique dual pistols.
- Adorably Precocious Child: He looks like he's in his preteens, but acts much more mature. His design is obviously intended to play up the cute aspect of this. However, it's later revealed that he's actually immature for his chronological age, which somewhere around 30.
- Artificial Human: Jr. is a URTV, a human specifically designed and created to fight U-DO.
- Badass Longcoat: In Episode I and Episode II. In Episode III he gets a Badass Shortcoat.
- Bond One-Liner: Usually as part of his victory pose after battle:
- Episode I: "Sayonara, baby!"
- Episode II: "I'll be sure to send you some flowers."
- Episode III: "Try again in ten years!"
- Bottomless Magazines: In multiple scenes, Jr. is seen firing many more shots then what would be possible from a pistol.
- Cloning Blues: He, like the rest of the URTV army, is a child clone of mad scientist Dmitri Yuriev.
- Compensating for Something: Shelley implies this is why he uses guns.
- Cultured Warrior: In contrast to Albedo who is just Wicked Cultured.
- Expy: He has the same weapons and similar attacks to Billy Lee Black from Xenogears, which may also be where his religiously-themed clothing and Angelic Requiem attacks come from. His personality and role, however, is closer to Bart.
- Guns Akimbo
- The Gunslinger: Jr. is the perfect example of when this trope is used outside of Westerns and works.
- Improbable Aiming Skills
- Real Men Wear Pink: He has a pink shirt (or sweater) under his Badass Longcoat in Episode II
- Really Seven Hundred Years Old / Never Grew Up: Jr's powers have frozen his physical age in his late preteens or early teens. He's really in his twenties and the oldest of the variants (including Gaignun). It's also implied he can live as long as he wants, having The Ageless type Immortality.
- Redheaded Hero
- Red Oni, Blue Oni: Red to chaos' and Gaignun's blue.
- Super-Powered Evil Side: Or rather, Superpowered Berserker Side
- Twin Telepathy: Between all the remaining URTVs, but especially strong with his formerly conjoined twin, Albedo.
- Warrior Poet: Jr. likes to quote from books, which are considered antiques by Xenosaga's time. One 4Koma pokes fun at this by having Allen being bewildered at how to even start reading one.
- Weapon of Choice: Jr. wields dual pistols because he's so fond of Gunslinger heroics.
- You Are Number Six: He is URTV #666, also codenamed Rubedo.
- Young Gun: In addition to being The Gunslinger, Jr. completely fits this role as well. He's both, because he is actually over twenty years old and is definitely experienced enough to be an actual gunslinger. However, since he looks and acts like a typical Young Gun, he fits this too. The only difference is that he's not attached to any sort of older mentor.
Shion's brother, a slacker who abandoned medical practice shortly after completing his training and bounces from obsession to obsession. He currently runs a book shop full of actual paper books, which baffles and infuriates Shion. He has a history with chaos, and was deeply involved with the incident on Old Miltia that led to it being sealed away.
- Absurdly Sharp Blade: Jin's sword can cut through just about anything.
- Aloof Big Brother: To Shion. He admits he does this out of fear of her completely rejecting him.
- Apologetic Attacker: "Forgive me."
- Badass Bookworm: Jin is this to the point that he owns his own bookstore. Jr. is a subversion of this. He loves reading to the point where he still caries around paper books in an age where they're considered antique (and acting like a kid in a candy store with Jin's bookstore), but is also very emotional and Trigger Happy.
- Badass Normal: Jin is perhaps the only "normal" human in the group, and only KOS-MOS can rival him at being the biggest badass.
- BFS: Subverted by his normal sized katana in melee combat, but played dead straight while in his ES (giant mecha).
- Charles Atlas Superpower: Jin can slice through giant mecha with a sword, while ostensibly being a normal human.
- Counter Attack: One of Jin's skill trees.
- Expy: Of Citan Uzuki from Xenogears.
- Heroic Sacrifice
- Katanas Are Just Better
- Renaissance Man: He usually changes careers once every six months out of sheer boredom with civilian life.
- Trademark Favorite Food: Curry.
- Upgrade Artifact: He gets one in Episode III, after Margulis dies.
A mysterious girl who appears before Shion many times, starting when she first encounters the Zohar. She seems to have a connection to chaos.
Shion: What do you want? Are you here to say a bunch of cryptic things again and confuse me? You're always like that. You just appear in front of me, say whatever you feel like, then just watch without actually doing anything!
- Expy: She looks remarkably like Elly from Xenogears. Given the ending with her and Abel, this was probably very deliberate.
- Meaningful Name: Nephilim means "watchers" or "those who have come down."
- Oracular Urchin
- Really Seven Hundred Years Old: Due to being a Virtual Ghost.
- Theme Naming: Nephilim's name follows along nicely with Albedo and the other Testaments.
- Virtual Ghost: Made possible since the consciousness of the dead can be found within the UMN.
- What Do You Mean Its Not Symbolic: Her necklace is in the shape of a cross, her name is a direct reference to the giants from the Bible who created the Great Flood...let's not get started on the symbolism behind the white and her possible relation to Elly.
- Woman in White
Voiced by Dave Wittenberg (games) and Blake Shepard (anime) in English.
Shion's subordinate, who has a hopeless crush on her. He has a tendency to whine and get weepy and emotional when faced with adversity.
- Butt Monkey
- Cannot Spit It Out: He has a crush on Shion, but can't work up the nerve to tell her. Justified: Shion hasn't had the nicest of lives, especially with people that are close to her. He's afraid that in getting close to her, he'll end up hurting her more by reopening old wounds or otherwise. When he does work up the courage to say it, however...
- Determinator: During his Crowning Moment of Awesome.
- Guest Star Party Member: Uses a cross-bow weapon in battle, when he briefly joins the party in Episode III.
- Hannibal Lecture: To Kevin.
- Nice Guy
- Non-Action Guy: Then subverted when he finally stands up to Kevin. And kills a Gnosis. With a rifle's butt!
- You also get to have him in battles in the third game where he wields a crossbow.
- Only Sane Man: The only vanilla human who tags along with the party.
- Secretly Wealthy: Evidently, Allen comes from a wealthy family but he never flaunts it and prefers not to rely on their help.
- Spanner in the Works: Maybe, depending on your interpretation of Wilhelm's ultimate goals.
- The So-Called Coward
- Took a Level in Badass: In the end, he bludgeons a Gnosis to death with a rifle butt, after delivering a Shut UP, Hannibal to The Dragon.
Voiced by Emi Uwagawa in Japanese and Michelle Ruff (Episode I) and Heather Hogan (Episode II & III) in English.
Miyuki is a systems programmer for Vector and an amateur inventor. She is very fond of Shion and goes out of her way to help her out with her inventions when she can.
- Butt Monkey: Played for laughs.
- Flanderization: She suffers from this horribly in the third game, turning her into a Butt Monkey ditz with everyone showing little faith in her doing ANYTHING right and treating her pretty horrible as a result, especially by Shion.
- Gadgeteer Genius: Of a slightly toned down variety. She's invents all of Shion's MWSs, including her Infinity+1 Sword version, plus KOS-MOS's Infinity Plus One Scythe in Episode I. Her hobby is sending off patent applications to the Federation Patent Office.
- Genius Ditz
- Guest Star Party Member
- Otaku: For weaponry.
- Swiss Army Weapon: She designed the MWS, Shion's weapon in the game. When she joins you she fights with the older version Shion used in Episode I.
A specialized Realian built with enhanced memory, reflexes, and suppressed emotion. He pilots the ES Asher.
- Dying Moment of Awesome
- Guest Star Party Member
- Heroic Sacrifice: With some marks for being a Guile Hero by using the otherwise nigh-unbeatable Voyager's power-lust against him.
- Knife Nut
- Neuro Vault
- The Mole: Although he is not aware of it.
- Really Seven Hundred Years Old: Canaan's mind is actually that of Lactis, the Realian that helped Ziggy back when he was alive. He doesn't remember this.
- The Stoic
Kevin Winnicott / The Red Testament / Roth Mantel
The former head of the Third Division, KOS-MOS's original designer, and Shion's fiance. Deceased at the time the game opens.
Or so you are meant to think. He orchestrated his own demise at the hands of the KOS-MOS archetype in order to become a Testament and help Wilhelm. His reasons for doing so is so that his time with Shion can last forever.
- Back from the Dead
- The Dog Bites Back: He betrays Wilhelm only when said Big Bad starts to tell him how much he failed at his role in his Xanatos Gambit and tortures Shion by karate chopping his arm off. When that doesn't work, he literally stabs Wilhelm In the Back, killing the both of them, so the party can save the universe.
- Knight Templar: Arguing that everything he did was to save Shion's life, even if it meant breaking her and use her.
- Love Makes You Evil: Kevin becomes a Testament to save Shion, who briefly returns the favor by becoming his minion in a boss fight.
- Memento MacGuffin / Tragic Keepsake: The pendent his mother gave him right before she gnostified, which he in turn passes on to Shion.
- Posthumous Character: Or so you think.
- Punny Name: Roth Mantel means Red Cloak
- Secret Identity: Two of them.
- Shirtless Scene
- Stalker with a Crush
- Used to Be a Sweet Kid: Subverted to hell and back: He was a rotten, duplicitous little bastard even as a kid. Heck, he used to be a bad kid by comparison because at least he was a lot better at hiding it as an adult.
Lt. Luis Virgil/Blue Testament
Rank Lieutenant. He is a A.G.W.S. pilot stationed on the Woglinde and a veteran of the Miltian Conflict. A Jerkass who actively insults Shion's optimism and belief that Realians count as people. Is eventually killed by KOS-MOS because he kept getting in line of her fire.
Or he would have if he wasn't brought back by Wilhelm. He then becomes the Blue Testament, personality intact. His reason for becoming a Testament is tied into the Miltian Conflict. During the period, he lost his whole squad to Realians and would have died if he didn't get a transplant from a Realian named Febronia, who also took care of Shion. While recovering, the formerly hard-assed soldier eventually softens and the two fall in love. However, when all things went to hell, Febronia died. He blames himself for being too weak and not being able to protect her. Because of this, he rejected love and developed an intense hatred towards Realians. The reason he hates Shion's optimism so much is because she reminds him of Febronia.
- Ascend to a Higher Plane of Existence
- Back from the Dead: Justified by Wilhelm's power
- Boss Banter
- Capulet Counterpart: With Febronia
- Hidden Depths: Wouldn't have pegged him for a guy who'd been deeply in love, huh?
- Fantastic Racism / Just a Machine: How he views Realians.
- Guest Star Party Member
- Jerkass: Mainly towards Shion and Realians.
- Love Hurts: This and Survivor Guilt is his whole reason for being the way he is. However...
- Not So Different: Between him and Shion. One way he tries to break her optimism.
- Likable Villain: It takes a long while for you to see what his deal is, but once you do, it's time to cry...
- Roaring Rampage of Revenge: When the out-of-control combat Realians kill Febronia, goes along with his Tear Jerker.
- Schrödinger's Cast: In Xenosaga: The Animation, Virgil survives the attack on the Woglinde in place of Commander Cherenkov, only to be killed later by KOS-MOS (for the same reason as in the game).
- Survivor Guilt: A major part of his character.
- Together in Death: With Feb.
- What Do You Mean Its Not Symbolic: Virgil was the name of Dante's guide from The Divine Comedy and the writer of The Aeneid.
Voiced by Koichi Yamadera (adult) and Mikako Takahashi (child) in Japanese and Crispin Freeman (adult, games), Jennifer Hale (child, Episode II), Wendee Lee (child, Episode III), and John Gremillion (anime) in English.
The head of the Kukai foundation and actually Jr.'s "brother" of sorts.
- Artificial Human: He is a URTV.
- Grand Theft Me: And eventually steals Albedo's body in Episode III, and himself gets hijacked by Dmitri Yuriev
- Heroic Sacrifice: Kills himself and grants Albedo's wish of reuniting with Rubedo.
- You Are Number Six: He is URTV #669, also codenamed Nigredo.
The pilot aboard the Elsa who has "immaculate piloting skills." At least, according to him.
Tony's childhood friend and the navigator of the Elsa. His hacking skills are reportedly top-notch, and Vector has tried repeatedly to hire him.
- Expy: Of Hammer from Xenogears, minus the anthromorphic rat aspects.
- Playful Hacker: So good that Vector scouted him but he always declined.
Mary and Shelley
A pair of sisters rescued from cruel experimentation by a pharmaceutical company by the Kukai foundation. They serve as Gaignun and Jr.'s secretaries and seconds-in-command.
- Break the Cutie: Their back story before Gaignun rescued them.
- Bridge Bunnies
- Meaningful Name: They are named after Mary Shelley, the author of Frankenstein. Which makes sense, considering the cybernetic and genetic modifications done to them.
- Red Oni, Blue Oni: Mary and Shelley, respectively.
- You Gotta Have Purple Hair: Shelley.
Pronounced "oo-doo". It's an acronym for Unus-Mundus Drive Operation. Despite the deception, it is not a computer program.
An indescribably powerful and alien entity, U-DO is an Energy Being that lives in UMN space, discovered by Dimitri Yuriev. Able to drive people insane through mental contact alone, it is a malevolent creature with no regard for humans...
Except for the part where all that turns out to be boldface fabrications by Yuriev. While it does drive people insane-see Albedo-this is mostly accidental on it's part. In reality, it is the sentient avatar of the mind of the universe, a Gnostic God who possesses a benign, scientific interest in humans. Unfortunately, it's mind is so powerful it literally destroys the minds of most people it attempts to contact. As shown throughout it's interviews with Shion in game #3, it seeks to understand the goals and psychology of humans and the nature of the universe. To do that, it created two observational units-Abel, a Fei Expy who gathers information in physical space, and Abel's Ark, a colossal-star system sized-living ship who observes spiritual space. It is an important element in all three games.
- Brown Note / Mind Rape: Coming into contact with U-DO has this effect. The exact effects is the individual learning what U-DO has seen. Namely, isolation enough to drive a person mad and the end of the universe.
- Cool Ship: Abel's Ark, which is absolutely fuggin' huge, having a solar system as an interior decoration
- Counterpart Comparison: In-universe example. Since Abel's Ark lives in the same spiritual dimension as the Gnosis, people initially assume it to be a Gnosis Mother Ship like the Cathedral Ship.
- Cosmic Horror: Subverted. It's simply a completely alien existence from a higher dimension. And it's curious about humans in a scientific way.
- Crystal Dragon Jesus
- Eldritch Abomination: Benign or not, it's still Yog-Sototh lite.
- Fun with Acronyms
- God in Human Form: Well God In Human And Cool Ship Form, anyhow.
The extremely creepy and Axe Crazy recurring villain who delights in tormenting Jr. He has an obsession with MOMO that goes above and beyond seeking the data locked inside her.
- A God Am I: In heaping plates of ham.
- Ascend to a Higher Plane of Existence
- Ax Crazy: And then some. Also one of the most pure examples of "crazy" in media. Most of the time, Ax Crazy is simply extremely vicious sociopaths with little regard to human life. Albedo personifies the truly insane elements by making semi-coherent references to various works, often randomly and with the loose relevance to the current issue and has a warped pattern of speech ("I am the ultimate telomerase!" when he's referencing his immortality). To be fair, though, this is due to being corrupted by U-DO.
- Back from the Dead: No less than three times in Episode II, for a given amount of "dead."
- Big Brother Attraction: To Jr.
- Bishonen: He's pretty attractive despite all the crazy, and has a whole lot of fangirls.
- Black Cloak: Although it is technically white, the usage and effect is the same.
- Chewing the Scenery: Albedo's made a feast of it.
- Clingy Jealous Boy: To Jr., especially as a kid.
- Combat Sadomasochist
- Creepy Child: Boy, was he ever.
- Death Seeker: All he thinks he wants is for Jr. to kill him at last.
- Drunk on the Dark Side: Albedo firing Proto Merkabah at Second Militia definitely qualifies. Also, this trope is a part of what he wants, overall, since he wants to link up with U-DO again so badly. Also, commenting on his first link up with U-DO...
Albedo: I experienced but a fragment of my true power that day. The waves that inundated my body, are now apart of me. I've reached a higher stage of existence, compared to you incomplete mortals. I am the Alpha AND the Omega of perfect consciousness!
- Establishing Character Moment: While he's featured in several scene's beforehand, Albedo's infamous Mind Rape scene is this in spades.
- Evil Albino: Boy, howdy!
- Evil Is Hammy
- Evil Laugh: Albedo's even dwarfs Kefka's in sheer insanity. Kefka's was jolly, jovial wickedness. Albedo's is the kind of thing you'd expect to hear in a mental institution. It's safe to say Albedo's runs laps around Kefka's and has energy (and lunacy) to spare.
- Evil Twin / Cloning Blues: To Jr. More-so than Gaignun as Jr. and Albedo were conjoined twins.
- Evil Tastes Good: "Feed me your hostility! Pierce me with your hatred!"
- Foil: To both Gaignun and Jr.
- From a Single Cell: Technically, from a single particle.
- Go Mad from the Revelation/Freak-Out: Twice; first one was when he learned that his brothers lack his infinite regeneration and could die, and the second is when he came into contact with U-DO.
- Healing Factor: Arguably his defining characteristic.
- The Hedonist: His quest to tap into U-DO again and to be killed by Jr. and, arguably, to then be reunited with Jr.
- I Cannot Self-Terminate: No, seriously. He can (and does) blow off his own head (repeatedly) and survive without a scratch.
- Laughing Mad: Especially as a kid.
- Large Ham: The hammiest character in the series, bar none.
- Lolicon: Has a disturbing fixation on MOMO and her Kirschwasser sisters eventually revealed because MOMO was based on Sakura, whom Jr. had a crush on. It's up to anyone's guess how much of this is him having a fetish, him trying to get Jr. to hate him, him being jealous of Sakura, or some combination of the above.
- Manipulative Bastard: He is able to make both MOMO and Jr. dance to his tune, usually by predicting their responses with near perfect accuracy.
- Mind Rape: Is very fond of this when around MOMO and Jr.
- Nietzsche Wannabe: Justified. You'd be pretty damn nihilistic too if you were so unkillable that'd you'd get to see the heat death of the universe first-hand and got a preview of it from the local Cosmic Horror.
- Nightmare Fuel Station Attendant
- Noble Demon: While he doesn't pull a full-on Heel Face Turn, he does just as much good for the party as he does acts of indiscriminate evil. This is most evident as the White Testament.
- Omnicidal Maniac: Albedo tries to blow up a planet. When that gets foiled, he just tries to drop the giant space station on it. However, this all may have been an act to get Jr hate him enough to kill him, as Jr is the only one who actually can neutralize U-DO's waves. Albedo would prefer getting killed than watch his brothers, mainly Jr, die.
- Psycho for Hire: Though this trope alone wouldn't encompass his craziness.
- Psychopathic Manchild: Type C
- Redemption Equals Death: He does this three times and every time it looks like he's gone for good, however, he just won't stay dead-- He's molecularly reassembled by the Testaments, killed again by Jr., brought back as a Testament himself and dies again when his mind is absorbed by Jr. and his body is obliterated.
- Required Secondary Powers: His Healing Factor.
- Suicide by Cop: He Can Not Self Terminate, so he repeatedly attempts to provoke Jr. into killing him.
- Terms of Endangerment: His frequent referral to MOMO as Ma belle péche or a variant of said phrase.
- Twin Telepathy: Although all the URTVs can communicate telepathically, the link between Jr. and Albedo is especially strong, with Jr. even able to sense when Albedo is reduced to particles.
- Too Kinky to Torture:
"This pain. It's SO GOOD! SO GOOOOD!"
- White-Haired Pretty Boy: For a given amount of "pretty."
- Who Wants to Live Forever?: Albedo has infinite regeneration, meaning he absolutely cannot die. Even if he is reduced to mere particles. Needless to say, upon learning that his brothers lack this regeneration, he takes it very badly. It Got Worse after contact with U-DO.
- Wicked Cultured: Tosses literary references left and right in some of his more prominent scenes. Played with too; the way he makes references doesn't make him seem so much as "cultured" as completely insane.
- You Are Number Six: He is URTV #667.
- Your Head Asplode: Repeatedly but to little effect.
The Grand Inquisitor of the Ormus religion, Margulis is ultimately only answerable to the Ormus Pope. He seeks the Zohar as a source of power and a relic of his religion. He is driven by a fiery faith, which ultimately burns himself as often as it smites his enemies.
- Big Bad: Of Episode 1. Demoted to Dragon in Episodes 2 and 3.
- Better to Die Than Be Killed: To Jin, despite the fact that Jin didn't really want to kill Margulis in the first place.
- Dragon-in-Chief: He's always second-in-command to the leader of Ormus, whoever it maybe from one moment to the next, yet he's always the one giving the orders. Until he suddenly isn't.
- Even Evil Has Standards: He apparently has a distaste for torture, since he refers to Albedo as having "perverse taste in hobbies." Well, it's either torture or the...other...things that Albedo does.
- Evil Counterpart / Foil: To Jin. Compare their styles: Jin fights without losing his cool while Margulis fights like The Berserker. Jin uses a Katana while Margulis uses a straight double-edged sword. During their dual, Margulis seems to have superior physical prowess while Jin is better at Ether-based attacks. Jin, and Shion by extension, have the blood of the People of the Zohar, which qualifies them to join Ormus. Jin didn't join while Margulis whole-heartedly embraced Ormus' teachings.
- Evil Redhead: In the more realistic almost brownish-red style.
- Gray and Gray Morality: Margulis is not strictly evil, and his greivences with the Federation are legitimate, especially the destruction of Michtam.
- Omnicidal Maniac: He destroyed (well, actually gnostified) an entire planet of several billion people in order to conduct Zohar link experiments. He doesn't seem to care, either, stating that the inhabitants were of no use to anyone.
- Knight Templar
- Say My Name: To Jin.
- Unwitting Pawn: To Wilhelm.
- Villainous BSOD: Upon learning that everything he believed about Ormus was a giant pretty lie Margulis has one hell of a Villainous BSOD.
- Worthy Opponent
Patriarch Sergius XVII
Voiced by Chikao Ōtsuka in Japanese and Michael Bell in English.
In public, Patriarch Sergius is the head of the galaxy's largest quasi-legal religion, the Immigrant Fleet, in private he's also the head of Ormus, the galaxy's largest religious terrorist cult. He is the immediate superior to much of the series's antagonists, namely Margulis, Pellegri, Sellers, and Heinlien.
- Big Bad Wannabe
- Church Militant
- Crystal Dragon Jesus is Catholic: Ormus is basically the Catholic Church In Space He's even referred to as The Pope in the Japanese version.
- Earthshattering Kaboom: He destroys Old Miltia by having the Ω System rip its way out of the planet's crust. Though Milita was uninhabited at the time, he is responsible for the largest amount of physical damage of all the villains until Wilhelm kicks off the Apocalypse at the end of Episode III.
- Even Evil Has Standards: He shares Margulis' distaste for Albedo.
- Everyone Calls Him "Barkeep": In Episode II, anyway. Margulis mentions him by name only in passing in Episode III.
- Evil Old Folks: He is the oldest-looking character in the series. The chronologically-oldest characters have him beat by gigayears. One of them is in your party, and has been alive since at least Jesus' time.
- First Church of Mecha: Ormus worships the Zohar as a holy relic and uses numerous religious-themed Humongous Mechas as part of their arsenal, including one that actually is a church. And then there's his own personal Deus Est Machina: Proto-Ω.
- Light Is Not Good: Dresses all in white? Check. Head of a major religion? Check. Light-based attacks? Check. Army of angelic super robots? Check. Base of operations looks like a space cathedral? Check. Genocidal tendencies? Double check.
- One-Scene Wonder: Although he's the primary antagonist of Episode II, he's a blip on the radar in the series as a whole.
- Out-Gambitted: By Wilhelm, spectacularly.
- Sinister Minister
The head of Vector Industries, the largest corporation in existence. It is also revealed that he heads up the second largest company, Hyams and the religious organization Ormus. He has some sort of connection to chaos (the guy) and commands the Testaments.
- Beethoven Was an Alien Spy: It's heavily implied that Wilhelm was either Emperor Nero or Tiberius.
- The Chessmaster: So much so that other chessmasters could learn from him.
- Creepy Monotone: He speaks only in a monotone. He is never shown to do anything else. Your Mileage May Vary on whether or not it's that creepy. Which can lead to...
- Deus Ex Machina: He acted as one for the protagonists in the ending sequence. Because the UMN had shut down, they had no way of getting away from Michtam quickly enough. Wilhelm created a gate so they could.
- Dissonant Serenity: Wilhelm, all the time. The most emotive he ever gets is a simple gasp when he realizes his Gambit Roulette just backfired...maybe.
- Emotionless Guy: Your Mileage May Vary on how good it is, (especially when he's actually around for more than one random scene or two) though.
- Fiction 500: He may be one of the wealthiest characters in the history of fiction, owning a company whose headquarters qualifies as an artificial planet.
- Interestingly enough, he actually manages to subvert the more prominent elements of this in a roundabout way. To note:
- Despite his status of being the CEO of Vector, very few people even seem to be aware of him (let alone of him having any status of being rich). For all intents and purposes, his office (which is a small room) on the Dammerung seems to double as his "house."
- He is rarely (if ever) seen buying anything for personal want (let alone things that would have insane prices).
- He funds things in his interest under the name of "Vector" rather than personally funding. This is a fair bit believable given Vector's history, scope and size. On the other hand, whenever he needs something built, he simply uses the various divisions of Vector and manipulates events in such a way that the products built have seemingly little to no relation to him. The stuff built is all relatively possible given the science used in the verse.
- The only times he defies physics is when he's literally defying the laws of physics, which never has anything to do with money or Rule of Funny/Cool.
- Interestingly enough, he actually manages to subvert the more prominent elements of this in a roundabout way. To note:
- Gambit Roulette: This may be one of the very few times this trope is justified, since he has possession of a device called the Compass of Order and Chaos, which shows him the movements of consciousness. Being several thousand years old probably doesn't hurt, either.
- He also has practically absolute control over the economy due to being the CEO of Vector and Hyams, as well as being a high-ranking Cardinal in Ormus. He was also head of the government a decade before the game takes place, giving him significant clout with the Federation.
- Judge, Jury, and Executioner
- Lean and Mean: Compared to contemporaries in the Xenosaga rogues gallery, he's a little on the thin side.
- The Man: He fits this, considering that he runs/ran, at the very least we know of, two rivaling companies (Vector and Hyams), Ormus, and at least one of the Militian government's Subcommities.
- Really Seven Hundred Years Old: Much, much more than seven hundred.
- The Stoic: If he has any emotions, the best we'll ever hear of it is him literally stating it.
- Time Abyss: He is at least 4000 years old and probably a lot older than that.
- The Ubermensch: Considering the Nietzsche subtitles and that Nietzsche's middle name was Wilhelm, this is not surprising.
- Blue and Orange Morality: He exists solely to prevent the destruction of the Lower Domain. He does not care for how many lives must be lost to achieve this goal.
- Ironically, blue and orange are the colors of chaos' outfit in Episode I.
- Blue and Orange Morality: He exists solely to prevent the destruction of the Lower Domain. He does not care for how many lives must be lost to achieve this goal.
- The Unfought
- Wicked Cultured: Likes to refer to all the events happening as if it were an opera, apparently listens to Wagner a lot, is never seen in anything other than a plain business suit and plays chess. Apparently, a whole freaking lot. He also has some elaborate and poetic titles for certain people and features ("shining wills" and refers to the White Testament as the "Weaver of the Eternal Circle of Zarathustra").
- White-Haired Pretty Boy
Margulus' subordinate within Ormus. Unlike her superior, she seems to have flashes of conscience about the paths they walk, but not enough to make her reconsider her choices. She has a past with Jin.
- Dark Action Girl
- Dating Catwoman: She and Jin were lovers in the past. They still have feelings for each other.
- Even Evil Has Standards: She protests the fact that so many lives (1.5 billion) were lost on Ariadne.
- Face Heel Turn
- The Fundamentalist
- Heroic BSOD: Post-Ariadne Incident, her attitude had changed.
- Jerk with a Heart of Gold
- Knight Templar: Not as much as Margulis, but enough to cause friction with Jin.
- Likable Villain
- Well-Intentioned Extremist
Dr. Dmitri Yuriev
Voiced by Osamu Saka in Japanese and Keith Szarabajka in English.
The "father" and creator of the URTVs. He is obsessed with destroying U-DO for an unknown reason.
- A God Am I: Wilhelm notes this as ironic; Yuriev's fear for U-DO, what he thought was God, lead him to attempt to become one.
- Big Bad Wannabe: Had Wilhelm not stepped up to the plate at the last minute, he would have been the Big Bad of Episode III.
- Body Surf: His time as hyperspace transit test subject granted him the ability to Body Surf, hence why he's Really Seven Hundred Years Old.
- Chessmaster: Again, comes in a close second to Wilhelm in the Manipulative Bastard category.
- Creepy Monotone: He speaks almost entirely in an "I'm a complete doucebag" tone.
- For Science!
- Go Mad from the Revelation: What happened when he came into contact with U-DO.
- Grand Theft Me: One of the ways he's lived for so long and an acquired skill from contact with U-DO.
- Jerkass: He's the only villain (aside from Voyager) with zero redeeming qualities.
- My Grandson, Myself
- President Evil: It's not explained very well in-game, but in the gap between Episodes II and III he has the Salvator faction stage a coup and install him as the Executive Committee Director of the Galaxy Federation.
- Really Seven Hundred Years Old
- Smug Snake
- Truly Single Parent: The URTV line are all enhanced clones of himself.
Voiced by Rena Mizuki in Japanese and Erin Fitzgerald and Stephanie Mitchell (child) in English.
URTV #668, the missing unit between 667 (Albedo) and 669 (Nigredo). One of very few female URTVs produced by the Yuriev Institute, she was groomed from childhood to be Yuriev's personal aide and pointwoman for the Salvator Faction.
- The Baroness: She's about as close as Xenosaga gets to this trope.
- Creepy Child: In Episode II, at least.
- Daddy's Little Villain: To Yuriev.
- Dark Action Girl
- Distaff Counterpart: To the male URTVs. Justified in-universe.
- Evil Redhead: She's a mass murderer.
- Never a Self-Made Woman: Her dad is Dimitri Yuriev, after all.
- Ninja Maid: To Yuriev.
- Opposite Gender Clone: She was created mostly from Yuriev's X-chromosome.
- She's All Grown Up: And killing people...
- Undying Loyalty: To Yuriev, again.
Voiced by Masaharu Satou in Japanese and Steve Blum in English.
One of the brightest scientific minds in the post-Miltian Conflict galaxy. Dr. Sellers is known as much for his intellect as he is for his shifting loyalties.
- Chronic Backstabbing Disorder: It's probably easier to list the people he hasn't screwed over.
- Cool Shades: Described as "motorized sunglasses" in the Episode I database. They're apparently bolted to his face.
- The Dragon: To Yuriev in Episode III.
- Early-Bird Cameo: He's not even named in-game when he shows up in Episode I for a minute or two. His proper introduction comes at the start of Episode II.
- For Science!
- Four Eyes, Zero Soul
- Genius Cripple: A self-made example. He ruined Joachim Mizrahi's life, so Mizrahi shot his kneecaps off.
- Karma Houdini: Other than the aforementioned knee-capping, he largely gets away scot-free in all three games.
- Mad Scientist
- Morally-Ambiguous Doctorate
- One-Scene Wonder: He's one of the principle villains of the story, yet his actual screen time is really quite minimal compared to Margulis, Yuriev, and the Testaments.
- Playing Against Type: Steve Blum as a slimey, frog-voiced, Non-Action Guy villain.
- Shoddy Knockoff Product: He openly admits his life's work is nothing but this, with his inspiration being Mizrahi's works.
- Sinister Shades: See: Cool Shades.
- The Unfought: In a rare twist, the party battles its way into the heart of the Merkabah to confront Sellers only for him lecture them about what what idiots they've been and then just float away in his hoverchair.
- What Happened to the Mouse?: He's one of the few dangling threads the series left behind, as he's never actually killed on screen. Everyone just assumes he stayed on the Merkabah as it was absorbed by Abel's Ark.
- You Are Too Late: He whips this out only after the fact, telling the party that while they've wasted their time battling their way through Merkabah, Yuriev has invaded The Durandal, and they're probably too late to do anything about it.
Voiced by Kouji Tsujitani in Japanese and DC Douglas in English.
The black testament, who has some sort of connection with Ziggy.
- Bald of Evil
- Black Cloak
- The Cracker: Before he became a supernatural monster he was a Ghost in the Shell-inspired cyber-terrorist with whom Ziggy tangled during his days as a policeman.
- Enigmatic Minion
- Evil Albino: Maybe. That or he's just frighteningly pale.
- Serial Killer
Voiced by Mariko Suzuki in Japanese and Bridget Hoffman in English.
A humanoid weapon system built on the same principles as KOS-MOS, and vastly more powerful. She states that she must destroy KOS-MOS in order to be complete.
- A.I. Is a Crapshoot: T-elos is cruel and sadistic, compared to KOS-MOS's logical indifference or protectiveness.
- Dark Action Girl: T-ELOS fits this to a T.
- Darkskinned Blonde: Technically white hair.
- Evil Counterpart: To KOS-MOS, although it's a little more complicated than that.
- Heel Face Turn: Not in her game, but when she appears in other games with KOS-MOS, T-elos usually wounds up in an Enemy Mine situation OR The Only One Allowed to Defeat You, so she teams up with KOS-MOS. Her characterization as a Face is mostly a high caliber Tsundere.
- Hollywoodyborg: Unlike KOS-MOS, who is a robot powered by Mary's soul, T-elos is a cyborg created from Mary's corpse, recovered from a time-displaced French tomb, but controlled by completely artificial computer brain.
- White-Haired Pretty Girl
- Zettai Ryouiki
