[[folder:Playable Characters (in order of appearance)]]
!!'''Shion Uzuki'''

!!!!!!Voiced by Creator/AiMaeda in Japanese and Creator/LiaSargent (Episode I & III), Olivia Hack (Episode II), and Stephanie Wittels (anime) in English.

Shion is the iron-willed but [[BunnyEarsLawyer 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 the main protagonist of the series.

* AcePilot: She piloted E.S. Dinah [[spoiler:Filia]] together with Miyuki in the beginning of Episode III.
* ActionGirl: 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.
* AllLovingHero: She treats KOS-MOS like a living being instead of a weapon and also feels sympathy for those that KOS-MOS was created to kill. She also insists on treating realians with the same respect as humans. Ironically, the minor exception is her brother, Jin, where their relationship is strained.
* AmbiguouslyBi: She only ever displays interest in men, but the more influence she has on KOS-MOS the more fanservice is added. [[spoiler: The final design when Shion rebuilds KOS-MOS is not only more revealing, but adds [[FanservicePack bigger breasts]].]]
* BadassNormal: She's the only vanilla human in the first game's party. She quickly crosses over into EmpoweredBadassNormal though.
* BareYourMidriff: In Episode III.
* BunnyEarsLawyer: Shion seems to be a pretty competent scientist when not needlessly risking her own life or forgetting important documents.
* CantStandThemCantLiveWithoutThem: In Episode I before she begins to trust KOS-MOS. This attitude is more prevalent in the anime version.
* CleavageWindow: Her vector uniform in Episode I has a has a hole here. Blame the designer.
* CombatMedic: Tends to learn both healing spells and a variety of attacks.
* CosmicKeystone: Wears it around her neck for the entire series without ever knowing it.
%%%%* DeusAngstMachina: So very, very much. See the trope page for the full story.
* DoomedHometown: Just replace "hometown" with [[UpToEleven home planet]].
* FanservicePack: Her outfits grow more fanservice-y in each episode, culminating in an exposed midriff, shorts and ZettaiRyouiki in episode III.
** Her Episode II costume is an aversion, however. It looks like sci-fi business casual.
* FearOfThunder: Understandable, since [[spoiler:her nanny, parents, and lover were all brutally killed in front of her during two different thunderstorms.]]
* FeminineWomenCanCook: She can kick some butts and still have feminine aspects. Her cooking was favorited by all the crew of Elsa because none of them can cook, but they still have to take turns to cook every single day aboard.
* FlowerMotif: Not the character, but her name. Soraya Saga says that every female character in the party was intended to have flower motif names.
%%* HairDecorations
* HeterosexualLifePartners: With KOS-MOS. When she and Kevin waited for KOS-MOS's awakening, they're like parents waiting for a baby to come out. Shion's motherly attitude towards KOS-MOS afterwards [[WordOfGod is even approved by CHOCO]] in Xeno Emission 3.
* HeroicBSOD: [[spoiler: After finding out she's the one who called the Gnosis into the real number domain and summoned Abel's Ark.]]
* HotScientist: 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.
* ImprobableAge: 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 hundreds of years. [[spoiler: 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. This was mostly accomplished by Kevin hand-picking her to be his NumberTwo, and then committing his ThanatosGambit, leaving her as his successor by default.]]
%%%* InnerMonologue: Shion does this every once in a while.
* ItsAllAboutMe: [[spoiler: A little over halfway through ''Episode III'', there's a universe-threatening danger going on. Shion wants to find her boyfriend very very badly. It takes a beat down from all of her friends and Allen's WorldOfCardboardSpeech to snap out of it.]]
* MagicKnight: She's primarily an Ether user, but she's also skilled in physical attacks.
* {{Magitek}}: Shion's special attacks apparently use an "Ether Circuit."
* {{Meganekko}}: For the first game only. Plus, he explains that she has perfect eyesight, and only uses the [[ChekhovsGun glasses to collect and analyze visual data]] in Episode III.
* MementoMacGuffin: The pendant that she's wearing belonged to Kevin's mom who's already passed away. [[spoiler:Turns out, the pendant is the Key that Wilhelm searched for.]]
* MiniDressOfPower: Her Vector uniform in Episode I is a short dress and a jacket with tights. It returns as an alternate outfit in III.
* MsFanservice: There's one cutscene in Episode III which views her with full blown swimsuit wear.
* NeverASelfMadeWoman: While she's a very capable engineer and she ''definitely'' didn't ask for it, the background details imply she's only the chief of the KOS-MOS project because she was banging Kevin and then inherited his position after the KOS-MOS archetype murdered him. [[JustifiedTrope Justified]] since [[spoiler:it was all part of Wilhelm's ThanatosGambit]].
* NiceGirl: Mostly, but when it comes to Jin sometimes she's this (dere-rere mode on) sometimes she's in her tsun-tsun mode.
* NoSocialSkills: She has ''moments'' of empathy for others, like her little chat with MOMO on the ''Durandal'' and her mercy killing of Cecile and Cath, but beyond that she can be pretty self-centered.
* ObliviousToLove: 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. [[spoiler: 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 occurred.
* OddFriendship: With Kazuya Mishima of all people...
* OfficialCouple: With [[spoiler:Allen]] at the very end.
* OutOfFocus: Despite being the main character, the plot focuses more on Jr. and Albedo than on her and KOS-MOS during the third act of Episode I and most part of Episode II.
* PalsWithJesus: Shion, in a past life, was called [[spoiler:the Maiden of Mary. It seems that she and Mary Magdalene (yes, ''that'' Mary Magdalene) were very close.]]
* PluckyGirl: She does rushes to fight Voyager and T-elos even though she knows they're much more stronger than her.
* PrettyInMink: Her jacket in ''III'' has a fur collar.
* {{Protectorate}}: To KOS-MOS.
* RomanticTwoGirlFriendShip: With KOS-MOS, by ''III'', they come off as closer than they any other two characters in the cast.
* RedOniBlueOni: The Red to Jin's and KOS-MOS' blue.
* ReplacementGoldfish: Of [[spoiler:Mary Magdelene,]] to a lesser degree than KOS-MOS.
* SecondLove: With Allen, after the party [[spoiler:defeated Zarathustra.]]
%%* ShesGotLegs
* ShutUpHannibal: Surprisingly she throw this to Albedo although she has no place between his and Jr.'s conflict.
* {{Stripperific}}: Her outfit in Episode III (above), although her outfits in I and II weren't exactly conservative either.
* SwissArmyWeapon: Shion's M.W.S. It's nerfed into a standoff weapon in ''Episode II'', but is rebuffed in ''Episode III''
%%* TeamMom
* TheCameo: She appears together with KOS-MOS and MOMO in ''VideoGame/NamcoXCapcom''.
%%* TheHeroine
* TomatoInTheMirror: She made contact with [[spoiler:the Zohar and summoned the Gnosis.]]
* TookALevelInJerkass: In Episode III, although mostly out of reaction to [[spoiler:knowing her own father took part in the Miltian Conflict, and later after knowing she called the Gnosis into their universe]]. Eventually gets better, though.
* TrademarkFavoriteFood: Curry. It's her specialty dish to make.
* TraumaCongaLine: '''HOLY SHIT''' does she go through a big one in Episode III. [[spoiler: Traveling back into the past, finding that her boyfriend worked with the U-TIC organization, which caused the end of her home planet, trying to save Virgil in the past when he's nearly dead just to see him die, and then meet up with cynical {{Jerkass}} present self. And then she finds out that she was responsible for summoning the Gnosis, and that her boyfriend was alive and gets torn between him and the friends she has.]]
* {{Tsundere}}: Particularly to her brother Jin.
* TVGenius: 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.
* WeaponOfChoice: The M.W.S. (Mobile Weapon System). In episode 1 it's a prototype BFG, but by 2 she upgrades to a smaller model.
* WhatMeasureIsANonHuman: Leads firmly towards to valuing anything sentient, Realians and humans.
* WhoWearsShortShorts: Episode III.
* ZettaiRyouiki: Episode III only.

** Bares a number of similarities to Seven of Nine from Star Trek Voyager. Blond haired, blue-eyed human turned into a cyborg against their will who develops an odd attachment to a child. They even display similar fashion sense and nearly identical hair styles.
* GuysSmashGirlsShoot: Suitable trope for both Ziggy and MOMO if you have them both in your party in Episode II and III.
* {{Hammerspace}}: Presumably he uses UMN transport for his {{BFG}}s, just like KOS-MOS.
%%* HiddenHeartOfGold
* HypocriticalHumor: 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.
* ICannotSelfTerminate: His self preservation directives prevent him from killing himself.
* IcyBlueEyes: He's a good man, though his eyes speaks differently.
* MightyGlacier: Up there with KOS-MOS in dishing out damage, but he's just as slow as his bulky metal limbs would imply.
%%* NervesOfSteel
* NoCelebritiesWereHarmed: His looks and attitude were based on Music/DavidBowie and his Ziggy Stardust persona.
* NotSoStoic: After he sees [[spoiler:Voyager]] in Episode II, we get to see him get ''pissed''.
* ParentalSubstitute: He's basically the father MOMO never had, going beyond his assigned mission of protecting her and praising her for accomplishments (such as piloting) and relating to her as an individual and a girl instead of a doll or a replacement.
%%* PowerFist
* PunnyName: His human name was Jan Sauer. Who's demeanour can easily be described as "sour"? You guessed it!
* ReallySevenHundredYearsOld: He is frozen at the age of his death, which is his early thirties. However, he is about 130 years old.
%%* TheStoic
%%* SummonToHand
* SwissArmyWeapon: Ziggy himself has one due to his cyborg modifications. He has stuff like blades, lasers, bludgeons, missile pods all installed in his arms and other body parts.
* TakeAThirdOption: 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 [[spoiler: puts his service pistol to his head and blows his brains out.]]
* ToBecomeHuman: Inverted. Ziggy is a human who wants to become a machine. The oddness of this request is noted given that Realians want to be recognized as fully living just like humans. It eventually played straight. He stops his mechanizing after some CharacterDevelopment from meeting MOMO and [[spoiler:finding out Voyager is alive.]]
* WeCanRebuildHim: Not that he ''wanted'' to be rebuilt...but they did it anyway after he died.

!!!!!!Voiced by Creator/RumiShishido in Japanese and Creator/SherryLynn (Episode I), Christina Puccelli (Episode II & III), and Creator/BrittneyKarbowski (anime) in English.

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.

* AcePilot: She pilots (Ziggy credited her for the pilot) the airship used by both of her and Ziggy during their flee from U-TIC. In the next games she pilots E.S. Zebulun.
* AgeInappropriateDress: Her ''Episode I'' outfit includes a very short skirt.
* ApologeticAttacker: Episode I only. "I'm sorry, are you okay?" is one of her standard battle ending phrases.
* ArtificialHuman: She's a Realian who was based on a real human.
* BunniesForCuteness: She receives a bunny stuffed animal in the anime version.
* TheCameo: She appears together with Shion and KOS-MOS in Namco X Capcom.
** She also appears with KOS-MOS in the second ''VideoGame/EndlessFrontier'' game.
* CherryBlossomGirl: She's based on Sakura Mizrahi, the deceased daughter of Juli and Joachim Mizrahi. MOMO's pink hair and status as a WhiteMagicianGirl (at least in the first two games) seems to be a reference to this trope.
* CuteBruiser: She's an adorable little girl who can dish out the pain like no other.
* DaddysGirl: 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.
* DangerouslyShortSkirt: In Episode I, resulted the panty shots all along.
* DistressedDamsel: In Episode I, she is held captive by the U-TIC which is why Ziggy was hired to rescue her at the start of the game. Later in ''Episode I'', [[spoiler: Albedo abducts her during the evacuation of the Kukai Foundation, from which the others need to rescue her]].
* DrivesLikeCrazy: During ''Episode II'''s ChaseScene. {{Justified|Trope}} in that she was driving away from people who were trying to capture her (with Jr., Ziggy and chaos beside her at the same time).
* FunWithAcronyms: Her name means "Multiple Observative Mimetic Organicus".
* GlassCannon: Her attacks hit hard, but she can't take damage very well.
* GuysSmashGirlsShoot: If you have her together with Ziggy in Episode II and III.
* HealingHands: She has nano technology curing ability.
* LivingMacGuffin: She has the Y-Data which contains ALL Joachim Mizrahi's research notes. And because of this, she was pursued by the U-TIC and Albedo.
** [[spoiler:In Episode II, Albedo finally succeeds to snatch it away from her]].
* TheLoad: A minor example in Episode I. Her low health, AwesomeButImpractical transformations and limited Ether spells mean that she's only useful as a back-row healer, which means she can't do anything ''but'' heal.
* MagicalGirl: In ''Episode I'', MOMO has in-battle {{Transformation Sequence}}s that give her special abilities. Seriously. Her name is also a ShoutOut to a classic magical girl, Minky Momo.
* MagicKnight: 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.
* MeaningfulName: MOMO means peach or peach blossom in Japanese. And this become the reason why Albedo calls her "ma peche" (my peach).
* TheMedic: Primarily a healing Ether user.
* MindRape[=/=]BreakTheCutie: By Albedo.
* MiniDressOfPower: In Episode I.
* MoralityPet: For Jr.
* MusclesAreMeaningless: 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 ''[[TheBigGuy Ziggy.]]'' Mull that one over. Possibly justified by her being a super-advanced Realian.
* NiceGirl: She's very kind to everyone she meets.
* NiceHat: In Episode II and III.
* PantyShot: Disturbingly often in episode I.
* ProperTightsWithASkirt: In Episode III.
* {{Protectorate}}: To Jr. and Ziggy.
* ReplacementGoldfish: To Ziggy for his dead child, presumably to Joachim for his daughter Sakura, and possibly to [[spoiler: Jr. for Sakura]].
** [[spoiler: Joachim and, eventually, Juli come to see her as a second daughter than a ReplacementGoldfish for Sakura. It's even mentioned that their personalities are very different.]]
* RobotKid: Though not technically a robot.
* RoseHairedSweetie: She has pink hair and she's really sweet and girly.
* TheStraightAndArrowPath: 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.
* ToBecomeHuman: 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 [[spoiler:gained an upgrade that would allow her to carry a child]].
* TomboyAndGirlyGirl: She's more girly than Sakura who Jr. mentioned to be more tomboy, according to Juli Mizrahi.
* TookALevelInBadass: From a MagicalGirl in Episode I to an impressive arrow shooter in the next Episodes.
* WellDoneDaughterGirl: She seeks approval from her "mother" Juli Mizrahi as something more than a replacement doll for her and her husband's deceased daughter, Sakura.
* WhiteMagicianGirl: Fits to a T in the first game, being primarily a support character, very feminine, a MysteriousWaif, and wielding a [[MagicWand rod]]. Her skillset is player defined in the second, and in the third, you can choose to make her a BlackMage or a [[BreakMeter break attacker]].
* YouGottaHaveBlueHair" Her hair is pink.
* ZettaiRyouiki: Episode I and II. We can only conclude that the character designer likes this trope.

!!!!!!Voiced by Erika Kawasaki in Japanese and Creator/BrianneSiddall (games) and Creator/GregAyres (anime) in English.

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 [[GunsAkimbo dual pistols]].

* AdorablyPrecociousChild: 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 is somewhere around 30.
* ArtificialHuman: Jr. is a URTV, a human specifically designed and created to fight U-DO.
* BadassLongcoat: In ''Episode I'' and ''Episode II''. In ''Episode III'' he gets a Badass ''Short''coat.
* BondOneLiner: 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'': "[[YearsTooEarly Try again in ten years]]!"
* BottomlessMagazines: In multiple scenes, Jr. is seen firing many more shots than what would be possible from a pistol.
* CloningBlues: [[spoiler:He, like the rest of the URTV army, is a child clone of mad scientist Dmitri Yuriev.]]
* CompensatingForSomething: Shelley implies this is why he uses guns.
* CulturedWarrior: In contrast to Albedo who is just WickedCultured.
* {{Expy}}: He has the same weapons, similar attacks, similar BadassLongcoat, and same baby face as Billy Lee Black from ''VideoGame/{{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 Fatima.
* GunsAkimbo: His WeaponOfChoice is a pair of pistols.
* TheGunslinger: Jr. is the perfect example of when this trope is used outside of Westerns and ''it works''.
* HotBlooded: He's very emotional and prone to jumping into things without thinking.
* ImprobableAimingSkills: One of his attacks in the first game, Storm Waltz, has him toss a bunch of coins into the air, then shooting every one of them, causing the bullets to ricochet off the coins and hit the enemies.
* NeverGrewUp: 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 TheAgeless type {{Immortality}}.
* OlderThanTheyLook: Since he's doesn't age, he looks like a pre-teen but is actually older than that.
%%* RedOniBlueOni: The red to chaos' and Gaignun's blue.
%%* SuperpoweredEvilSide
* TwinTelepathy: Between all the remaining [=URTVs=], but especially strong with his formerly conjoined twin, Albedo.
* WarriorPoet: 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.
* WeaponOfChoice: Jr. wields dual pistols because he's so fond of [[TheGunslinger Gunslinger heroics]].
* YouAreNumberSix: He is URTV [[NumberOfTheBeast #666]], also codenamed Rubedo.
* YoungGun: In addition to being TheGunslinger, Jr. completely fits this role as well. [[spoiler: He's both, because he is actually over twenty years old and is definitely experienced enough to be an actual [[TheGunslinger gunslinger]]. However, since he looks and acts like a typical YoungGun, he fits this too.]] The only difference is that he's not attached to any sort of older mentor.
!!'''Jin Uzuki'''

!!!!!!Voiced by Creator/HideyukiTanaka in Japanese, and Creator/CrispinFreeman (Episode I), Michael Gough (Episode II & III), and Creator/ChrisAyres (anime) in English.

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.

* AbsurdlySharpBlade: Jin's sword can cut through just about anything.
* AcePilot: Pilots E.S. Reuben.
* AloofBigBrother: To Shion. He admits he does this out of fear of her completely rejecting him.
* ApologeticAttacker: "Forgive me."
* AnIcePerson: Subverted, for it was his main element. Opposed to Margulis's fire element.
* BadassBookworm: Jin is this to the point that he owns his own bookstore. 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 TriggerHappy.
* BadassNormal: Jin is perhaps the only "normal" human in the group, and only KOS-MOS can rival him at being the biggest badass.
* BashBrothers: With chaos.
* {{BFS}}: Subverted by his normal sized katana in melee combat, but played dead straight while in his ES (giant mecha) which carries a pair that are almost as long as it is tall.

* CrypticConversation: [[LampshadeHanging She gets called out on it at one point. ]]
-->'''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 ''VideoGame/{{Xenogears}}''. [[spoiler: Given the ending with her and Abel, this was probably very deliberate.]]
* MeaningfulName: Nephilim means "watchers" or "those who have come down."
%%* OracularUrchin
* ReallySevenHundredYearsOld: Due to being a VirtualGhost.
* ThemeNaming: [[spoiler:Nephilim's name follows along nicely with Albedo and the other Testaments.]]

%%* ButtMonkey
* CannotSpitItOut: 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. [[CrowningMomentOfAwesome When he ''does'' work up the courage to say it, however...]]
* {{Determinator}}: During his CrowningMomentOfAwesome.
%%* DoggedNiceGuy
* GuestStarPartyMember: Uses a cross-bow weapon in battle, when he briefly joins the party in Episode III. Sadly but [[ButtMonkey fittingly]], he's got Momo's frailty and lack of attack power, and [[TheBigGuy Ziggy's]] low Ether Points and Ether Attack.
%%* NiceGuy
* NonActionGuy: Downplayed in ''Episode I'' because while he may not be playable he is shown using a machine gun in cutscenes.

** You also get to have him in battles in the third game where he wields a crossbow.

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.

* ButtMonkey: Played for laughs.
* {{Flanderization}}: She suffers from this horribly in the third game, turning her into a ButtMonkey [[TheDitz ditz]] with everyone showing little faith in her doing ANYTHING right and treating her pretty horrible as a result, especially by Shion.
* GadgeteerGenius: Of a slightly toned down variety. She's invents all of Shion's [=MWSs=], including her InfinityPlusOneSword version, plus KOS-MOS's [[InfinityPlusOneSword Infinity Plus One]] [[SinisterScythe Scythe]] in Episode I. Her hobby is sending off patent applications to the Federation Patent Office.
%%* GeniusDitz

* BigGood: For the first half of the game.
* CoolOldLady: Creator/MaryElizabethMcGlynn plays her as one in the English dub.
%%* CoolShades

%%* GratuitousLatin

* {{Hikikomori}}: Bit of an enforced example. If she appears out in public, Vector will have her assassinated.
* TheMentor: To Shion (and Miyuki).
%%* MissionControl
%%* MsExposition
* OutOfFocus: After playing a major role in the ''A Missing Year'' and the ''Episode III'' prologue, she all but disappears after that, putting in sporadic appearances here and there before resurfacing in time for the epilogue.
* OrcusOnHisThrone: The real Doctus never appears until the denumont of ''Episode III''. Up to that point, she's been in hiding in an undisclosed location operating through remote controlled body doubles. [[JustifiedTrope Justified]] in that Vector apparently has a kill-on-sight order on her.
* QuicklyDemotedLeader: She's the leader of Scientia, but Shion seems to do all its legwork.
* RememberTheNewGuy: In all fairness, she's introduced in a canon interactive comic prior to her appearance in ''Episode III''. It was simply [[NoExportForYou never localized for North America]].
* SendInTheClones: She has a veritable army of android body doubles which she uses to interact with the outside world.
* TheStoic
* SurroundedByIdiots: While she points out "to err is human," her patience for Miyuki's constant screw ups is limited.
%%* VoiceWithAnInternetConnection
* WomanInWhite: Sure, it's more of an off-white, but the trope still stands.
* YourTerroristsAreOurFreedomFighters: Scientia has been branded an anti-Vector terrorist organization by the Galaxy Federation Government.

* TheDogBitesBack: [[spoiler: He betrays Wilhelm only when the guy starts to tell him how much he failed at his role in his EvilPlan and tortures Shion by ''karate chopping his arm off''. When that doesn't work, he literally stabs Wilhelm InTheBack, killing the both of them so the party can save the universe.]]
* EvenBadMenLoveTheirMamas: [[spoiler: The flashback where Wilhem recruited him as a child showed him hating the universe for his mother's death.]]
* {{Jerkass}}: [[spoiler: Outside of his genuine love for Shion and mentioning that he did love his mother, he's completely heartless and has no moral qualms about any of his actions, even the destruction of Old Mitlia. Even then, he's idea of love still doesn't spare Shion from everything he put her through while going along with Whilelm's plan. And [[ArsonMurderAndJaywalking he's a rude smug asshole.]]]]

%%* AscendToAHigherPlaneOfExistence

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.]]

An [[EldritchAbomination indescribably powerful and alien entity]], U-DO is an EnergyBeing that lives in UMN space, discovered by Dimitri Yuriev. [[MindRape Able to drive people insane]] [[BrownNote 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 [[BlatantLies 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, its mind is so powerful it literally destroys the minds of most people it attempts to contact. As shown throughout its 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 [[GodInHumanForm observational units]]-Abel, a [[VideoGame/{{Xenogears}} 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.

* BlueAndOrangeMorality: [[spoiler: Being from a higher dimension means it has difficulty understanding humans, but it wants to move past that any harm it does cause is unintentional.]]
* BrownNote[=/=]MindRape: Coming into contact with U-DO has this effect. [[spoiler: 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.]]
* CoolShip: Abel's Ark, which is absolutely fuggin' huge, having a ''solar system'' as an interior decoration.
* CounterpartComparison: In-universe example. [[spoiler:Since Abel's Ark lives in the same spiritual dimension as the Gnosis, people initially assume it to be a Gnosis MotherShip like the Cathedral Ship]].
* CosmicHorrorStory: [[spoiler:Subverted. It's simply a completely alien existence from a higher dimension. And it's curious about humans in a scientific way.]]
%%* CrystalDragonJesus
* EldritchAbomination: [[spoiler: Benign or not]], it's still [[Creator/HPLovecraft Yog-Sothoth]] lite.
%%* FunWithAcronyms
* GodInHumanForm: Well, [[spoiler:God In Human And CoolShip Form, anyhow]].
* GodIsFlawed: [[spoiler: A benign entity who wants to do good, but coming into contact with it tends to have very bad side effects.]]
* GodIsGood: [[spoiler: Despite being an EldritchAbomination who has difficulty understanding human morality, it wants to understand humans and wants to do good. But GodIsFlawed, and its actions cause harm and it doesn't even realize it.]]
* IntriguedByHumanity: Its true motives.

!!'''Andrew Cherenkov'''

* DarkAndTroubledPast: What we see of his past shows that it was terrible. It wasn't until he met Margulis off all people, that it started to get better.
* {{Expy}}: He is pretty much Ramses from Xenogears. [[spoiler:Neither like to be called 'garbage' either.]]



!!!!!!Voiced by Creator/KoichiYamadera in Japanese and Creator/CrispinFreeman in English.

The extremely creepy and AxeCrazy recurring villain who delights in tormenting Jr. He has an obsession with MOMO that goes above and beyond seeking the data locked inside her.

* AGodAmI: In heaping plates of ham.
* ArchEnemy: To Jr.
%%* AscendToAHigherPlaneOfExistence
* AxCrazy: And then some. ([[EvenEvilHasStandards Even Margulis is is disturbed by him]]). Also one of the most pure examples of "crazy" in media. Most of the time, AxCrazy 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 loosest relevance to the current issue and has a warped pattern of speech ("I am the ultimate telomerase!" when he's referencing his immortality). [[spoiler: To be fair, though, this is due to being corrupted by U-DO.]]
* BackFromTheDead: No less than ''three'' times in Episode II, for a given amount of "dead."
* BigBrotherAttraction: To Jr.
* BigNo: Does one when he finds out he's immortal and will outlive his brothers... [[TearJerker and then he hugs Rubedo...]]
* BilingualBonus: He makes a [[JustForPun cool pun]] in French at one point, using "pêche" to refer to MOMO - pêche and momo mean "Peach" in French and Japanese, respectively - and then calls himself a "péché," meaning "sin."
* BlackCloak: Although it is technically white, the usage and effect is the same.
* BlessedWithSuck: His immortality.
* BunnyEarsLawyer: Even to Ormus he mostly seen as a NecessaryEvil.
* [[ClingyJealousGirl Clingy Jealous Boy]]: To Jr., especially as a kid.
* CombatSadomasochist: Especially insane one because he does feel. Meaning that his is a...
* CreepyChild: Boy, was he ever. But also a...
* DeathSeeker: All he ''thinks'' he wants is [[spoiler: for Jr. to kill him at last.]]
* DemotedToExtra: In ''Episode III'', sadly.
* DrunkOnTheDarkSide: Albedo firing [[spoiler: Proto Merkabah at Second Militia]] definitely qualifies. Also, this trope is a part of what he wants, overall, since [[spoiler: he wants to link up with U-DO again so badly.]] Also, commenting on his [[spoiler: first link up with U-DO]]...
-->'''Albedo''': [[spoiler: I experienced but a fragment of my true power that day. ''The waves that inundated my body, are now a part 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!]]
* EstablishingCharacterMoment: While he's featured in several scenes beforehand, which notably showed that even Margulis is disturbed by him and wasn't bothered by the destruction of an entire planet, Albedo's infamous MindRape scene is this ''in spades''.
* EvilAlbino
* EvilLaugh: Albedo's even dwarfs [[VideoGame/FinalFantasyVI 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.
* EvilTwin[=/=]CloningBlues: To Jr. More-so than Gaignun as Jr. and Albedo were conjoined twins.
* EvilTastesGood: "Feed me your hostility! Pierce me with your hatred!"
* {{Foil}}: To both Gaignun and Jr.
* {{Expy}}: Sociopathic, a God of raw martial arts, and has a Freudian complex with another side of "himself"... real subtle, [[VideoGame/{{Xenogears}} Id]].
* FromASingleCell: Technically, from a single particle.
* GoMadFromTheRevelation[=/=]FreakOut: Twice; first one was when he learned that his brothers lack his infinite regeneration and could die, and the second is when he [[spoiler: came into contact with U-DO]].
* GoodThingYouCanHeal: Frankly, having Albedo die from [[spoiler: tearing his head off]] would've saved MOMO from the carnival of BodyHorror. [[WorldHalfEmpty It's just not one of those games]].
* HealingFactor: Arguably his defining characteristic.
* TheHeavy: In Episode 1, after the Gnosis attack the Kukai foundation he pretty takes over as the main antagonist.
* TheHedonist: His quest [[spoiler: to tap into U-DO again and to be killed by Jr. and, arguably, to then be reunited with Jr.]]
* ICanNotSelfTerminate: No, seriously. He can (and does) blow off his own head (repeatedly) and survive without a scratch.
* IThoughtEveryOneCouldDoThat: Assumed that the other URTVs had a HealingFactor like he, which fueled some of his more violent early behavior since he thought they couldn't die like him. When he learned they [[FreakOut couldn't]]...
* LargeHam: A pretty damn terrifying one given how it shows how batshit insane he is.
* LaughingMad: Especially as a kid.
* ManipulativeBastard: He is able to make both MOMO and Jr. dance to his tune, usually by [[BatmanGambit predicting their responses with near perfect accuracy.]]
* MindRape: Is ''very'' fond of this when around MOMO and Jr.
* NietzscheWannabe: 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 [[spoiler: the local cosmic entity]].
%%* NightmareFuelStationAttendant
* NobleDemon: While he doesn't pull a full-on HeelFaceTurn, he does just as much good for the party as he does acts of indiscriminate evil. This is most evident as [[spoiler:the White Testament.]]
* OffWithHisHead: In his EstablishingCharacterMoment, does this to '''himself'''. And follows it up by LaughingMad as he crushes it with his foot.
* OmnicidalManiac: Albedo tries to blow up a planet. When that gets foiled, he just tries to [[ColonyDrop drop the giant space station on it]]. [[spoiler: However, this all may have been an act to get Jr hate him enough to kill him, as Jr is the only one who can actually neutralize U-DO's waves. Albedo would prefer getting killed than watch his brothers, mainly Jr, die.]]
* PleaseDontLeaveMe: "Rubedo, don't leave me behind!"
* PsychoForHire: Though this trope alone wouldn't encompass his craziness.
* PsychopathicManchild: Type C
* RedemptionEqualsDeath: 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.
* RequiredSecondaryPowers: His HealingFactor.
* StartOfDarkness: His initial FreakOut when learning that everyone he knew would grow old and die and he stay alive forever.
* SuicideByCop: He [[ICanNotSelfTerminate Can Not Self Terminate]], so he repeatedly attempts to provoke Jr. into killing him.
* TermsOfEndangerment: His frequent referral to MOMO as ''Ma belle péche'' or a variant of said phrase.
* TwinTelepathy: Although all the [=URTVs=] can communicate telepathically, the link between Jr. and Albedo is especially strong, with Jr. even able to sense [[spoiler: when Albedo is reduced to particles.]]
* TooKinkyToTorture: Getting limbs shoot off, and even loses his head doesn't bother him.
--> "This pain. It's SO GOOD! SO GOOOOD!"
* WhiteHairBlackHeart: White hair. Is a total psycho.
* WhoWantsToLiveForever: [[UpToEleven Hoo, boy.]] [[spoiler: Albedo has infinite regeneration, meaning he absolutely cannot die. [[FromASingleCell 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 goes FromBadToWorse after contact with U-DO.]]
* WickedCultured: 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''.
* WoobieDestroyerOfWorlds: He started to get unhinged learning that everybody he'd either spend life along or watching everybody he knew die of old age. Then [[spoiler: he came into contact with U-DO, and what's worse, Jr. panicked and left him and the other URTVs to it.]]
* YouAreNumberSix: He is URTV #667.
* YourHeadAsplode: Repeatedly but to little effect.

!!!!!!Voiced by Creator/JojiNakata in Japanese and Creator/MichaelMcConnohie (games) and Andy [=McAvin=] (anime) in English.

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.

* AffectionateNickname: Jin seems to hold some respect for him as he continues to refer to Margulis as "Colonel" even when Margulis doesn't hold that rank anymore.
%%* AuthorityEqualsAsskicking
* BadassNormal: Margulis is to the villains as Jin is to the heroes in regards to this trope; he's an ordinary swordsman amongst {{Reality Warper}}s and he still puts out a good showing.
* BigBad: Of Episode 1. DemotedToDragon in Episodes 2 and 3.
* BetterToDieThanBeKilled: To Jin, despite the fact that Jin didn't really want to kill Margulis in the first place.
* {{BFS}}: His ES carries one that's longer than it is tall.
* BloodKnight: He enjoys his fights, which are among the few times in the series he seems to enjoy himself.
* ColonelBadass: Originally a colonel in the Federation military (hence the BadassLongCoat field uniform in the above picture) and still continues to be a badass.
* DragonInChief: He's always second-in-command [[spoiler:to the leader of Ormus]], whoever it maybe from one moment to the next, yet he's always the one giving the orders. [[spoiler:[[OutGambitted Until he suddenly isn't]]]].
* EvenEvilHasStandards: While he's not bothered by sacrificing lives for his goals (read, whole planets), he apparently has a distaste for torture, since he refers to Albedo as having "perverse taste in hobbies."
* EvilCounterpart[=/=]{{Foil}}: To Jin. Compare their styles: Jin fights without losing his cool while Margulis fights like TheBerserker. 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. [[spoiler: 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.]]
* EvilRedhead: In the more realistic almost brownish-red style.
* FlashStep: Displays the when fighting Jin and also in a flashback with [[spoiler: Cherenkov]] when the two first met when dodging an attack from him and then knocking him with a karate chop.
* GoodScarsEvilScars: Get's a scar from one of his fights with Jin.
* GrayAndGrayMorality: Margulis is not strictly evil, and his greivences with the Federation are legitimate, especially the destruction of Michtam.
* PersonaNonGrata: Originally a colonel in the Federation military (hence the BadassLongCoat field uniform in the above picture), he was revealed as a traitor at the climax of the Miltian Conflict and is now a wanted criminal, unable to return to Federation space. This is the reason he's usually only seen on Ormus ships/battlestations or on dead worlds like Michtam and Old Miltia.
* KnightTemplar
* LargeHam: He's usually TheStoic, but once he's into a fight, he [[ScreamingWarrior screams and roars like a beast]]. Not only that, but most if not all of his battle quotes are [[NoIndoorVoice yelled at the top of his lungs.]]
--> '''Margulis''': I'll send you all TO HEEELLLLLL!!!
* SayMyName: To Jin.
--> "'''UZUKI~~~~'''"
* UnwittingPawn: To Wilhelm.
* UtopiaJustifiesTheMeans: He dispasionately destroys ([[spoiler:well, actually gnosifies]]) a planet of 1.5 billion people in order to conduct a Zohar link experiment. He doesn't seem to care, either, stating that the inhabitants were of no use to anyone. It's all in the name of [[spoiler:finding some way to return to [[EarthThatWas Lost Jerusalem]]]].
* VillainousBSOD: Upon learning [[spoiler:that everything he believed about Ormus was a giant pretty lie]] Margulis has one hell of a Villainous BSOD.
* WorthyOpponent: Sees Jin as one and despite the hostility between them does respect him.
!!'''Patriarch Sergius XVII'''
!!!!!!Voiced by Chikao Ōtsuka in Japanese and Creator/MichaelBell in English.

In public, Patriarch Sergius is the head of the galaxy's largest quasi-legal religion, the [[CrystalDragonJesus 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.

* BigBadWannabe: He manages to be a huge threat throughout ''Episode II'' and gets his hands on the WeaponOfMassDestruction he intended to along with the Zohar, but then it turns out he was just an UnwittingPawn to Wilhelm who was using him to get the Zohar.
* ChristianityIsCatholic: Ormus is basically the Catholic Church InSpace He's even referred to as UsefulNotes/ThePope in the Japanese version.
%%* ChurchMilitant
* EarthShatteringKaboom: 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 [[spoiler:until Wilhelm kicks off the Apocalypse at the end of ''Episode III'']].
* EvenEvilHasStandards: He shares Margulis' distaste for Albedo.
* EveryoneCallsHimBarkeep: In ''Episode II'', anyway. Margulis mentions him by name only in passing in ''Episode III''.
* EvilOldFolks: He is the oldest-''[[OlderThanTheyLook looking]]'' character in the series. The chronologically-oldest characters have him beat by ''gigayears''. One of them is in your party, [[spoiler: and has been alive since at least Jesus' time.]]
* FirstChurchOfMecha: Ormus worships the Zohar as a holy relic and uses numerous religious-themed {{Humongous Mecha}}s as part of their arsenal, including one that actually '''is''' a church. And then there's his own personal DeusEstMachina: Proto-Ω.
* LightIsNotGood: 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'''.
* OutGambitted: By Wilhelm, spectacularly.
* ProperlyParanoid: Is convinced that Margulis is plotting against him despite his apparent loyalty. He's right.
%%* SinisterMinister
* TakeOverTheWorld: What he planned to do Proto Ω, along with destroying the Gnosis.
!!!!!!Voiced by Creator/NobuyukiHiyama in Japanese and Creator/RichardCansino (Episode I), Jason Spisak (Episode II & III), and Creator/VicMignogna (anime) in English.

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.

* AgonyBeam: One of the few 'offensive' powers we see him using, which [[spoiler:Shion was on the receiving end of.]]
* BeethovenWasAnAlienSpy: It's heavily implied that Wilhelm was either Emperor Nero or Tiberius.
* BigBad: The one and only, though the "bad" part [[WellIntentionedExtremist is]] [[NecessarilyEvil debatable]].
%%* {{Bishonen}}
* BlueAndOrangeMorality: [[spoiler: 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.]]
%%* TheChessmaster
* CosmicEntity: Created specifically by the [[spoiler:Collective Subconscious to ensure the survival of the Lower Domain of the universe... [[WellIntentionedExtremist at any cost.]]]]
%%* CreepyMonotone
* {{Determinator}}: So it will take several [[spoiler: thousand]] years of manipulating mankind to achieve [[spoiler: Eternal Recurrence]]? No sweat. [[spoiler:It's not like he hasn't done it before or anything]].
* DeusExMachina: He acted as one for the protagonists in the ending sequence. Because the [[spoiler: UMN had shut down, they had no way of getting away from Michtam quickly enough. Wilhelm created a gate so they could.]]
* DissonantSerenity: Wilhelm, all the time. The most emotive he ever gets is a simple gasp when he realizes [[spoiler:his GambitRoulette just backfired... [[GambitPileup maybe]]]].
* {{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 Dämmerung 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 RuleOfFunny[=/=][[RuleOfCool Cool]].
* {{Foil}}: To chaos (the person). [[spoiler:And to a lesser extent, Mary Magdalene. ]]
* GambitRoulette: 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 [[spoiler: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 [[spoiler: 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.]]
* JudgeJuryAndExecutioner: He prefers not to get his own hands dirty, but if he needs somebody offed, he's more than willing to [[spoiler: sic a Testament on them.]]
* LeanAndMean: Compared to contemporaries in the ''Xenosaga'' rogues gallery, he's a little on the thin side.
* TheMan: 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.
* ManOfWealthAndTaste: Played with. He's well-dressed, immaculately groomed, and certainly wealthy, but he rarely if ever indulges in personal luxuries, aside from [[WickedCultured chess, opera music, and in one scene, wine]].
%%* MeaningfulName: His name is a reference to Creator/FriedrichNietzsche. Please explain why this is meaningful.
* NecessarilyEvil: Once Shion realizes just what it was he was doing (or rather, [[TheEndOfTheWorldAsWeKnowIt trying to prevent]]), she recognizes him as this.
* NonActionBigBad: The closest we see to him actually fighting is [[spoiler:the aforementioned use of an AgonyBeam.]]
%%* RedEyesTakeWarning
* TheStoic: If he has any emotions, the best we'll ever hear of it is him literally stating it.
* TimeAbyss: He is at least [[spoiler:4000 years old. Supplementary material suggests not only has he been around since the birth of the universe, he's been going around the StableTimeLoop an ''uncountable'' number of times prior to Shion and KOS-MOS sabotaging Zarathustra. So it's possible Wilhelm is '''quadrillions''' of years old, probably even more]].
* TheUbermensch: Considering the Nietzsche subtitles and that Nietzsche's middle name was Wilhelm, this is not surprising.
%%* TheUnfought
* WalkingSpoiler: Just in case all of the spoiler tags weren't enough of a clue.
* WellIntentionedExtremist: His goal is to [[spoiler: save the universe.]]
* WickedCultured: 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, [[TheChessmaster 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").

!!!!!!Voiced by Creator/ErikoHara in Japanese and Creator/KariWahlgren (games) and Creator/ChristineAuten (anime) in English.

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.

%%* DarkActionGirl
* DarkSkinnedBlonde: Depends on which official art you're looking at.
* DatingCatwoman: [[spoiler: She and Jin were lovers in the past. They still have feelings for each other.]]
* EvenEvilHasStandards: She protests the fact that so many lives (1.5 ''billion'') were lost on Ariadne.
%%* FaceHeelTurn
* FauxAffablyEvil: According to the Episode III database, her reasonable demeanor is a facade.
%%* TheFundamentalist
* HeroicBSOD: Post-Ariadne Incident, her attitude had changed.
%%* JerkWithAHeartOfGold
* KnightTemplar: Not as much as Margulis, but enough to cause friction with [[spoiler: Jin]].
%%* LikableVillain
* MidSeasonUpgrade: She becomes an active antagonist in ''Episode II'' after Margulis gives her ES Isachaar to pilot.
* TheMole: Just like Margulis, she was an Ormus mole in the Federation military at the time of the Miltian Conflict (as evidenced by her picture above wearing a Federation uniform).
* SatelliteCharacter: To Margulis in Episode I.
* WeaponOfChoice: BladeOnAStick--both on foot and in Isachaar.
%%* WellIntentionedExtremist
!!'''Dr. Dmitri Yuriev'''
!!!!!!Voiced by Osamu Saka in Japanese and Creator/KeithSzarabajka in English.

The "father" and creator of the [=URTVs=]. He is obsessed with destroying U-DO for an unknown reason.

* AGodAmI: Wilhelm notes this as ironic; Yuriev's fear for U-DO, what he thought was God, lead him to attempt to become one.
* BadassBookworm: Shortly after making his entrance, he pulls a coup and frees TheFederation from the influence of [[CorruptChurch Ormus]]. He then proceeds to build several [[WeaponOfMassDestruction weapons of mass destruction]] and leads the only faction in the game that isn't [[spoiler: directly controlled by [[TheChessmaster Wilhelm]]]].
* BigBadWannabe: A a very effective one, enough to be a SpannerInTheWorks in ''Episode II''. Had Wilhelm not stepped up to the plate at the last minute, he would have been the BigBad of ''Episode III''.
* BodySurf: His time as hyperspace transit test subject granted him the ability to BodySurf, hence why he's ReallySevenHundredYearsOld.
* ChessMaster: Again, comes in a close second to Wilhelm in the ManipulativeBastard category.
%%* CreepyMonotone
%%* ForScience
* GoMadFromTheRevelation: What happened when he came into contact with U-DO.
* GrandTheftMe: One of the ways he's lived for so long and an acquired skill from contact with U-DO.
* ItsAllAboutMe: Unlike other villains, he's motives are entirely selfish, and doesn't care about anything but himself. He even outright mocks the URTVs who disobey him as failures.
%%* MyGrandsonMyself
* PresidentEvil: 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.
%%* ReallySevenHundredYearsOld
* TheReasonYouSuckSpeech: Delivers a number to Jr. [[YouHaveFailedMe deriding him for failing]] [[ItsAllAboutMe the purpose Yuriev created him for]].
%%* SmugSnake
* TrulySingleParent: The URTV line are all enhanced clones of himself.
!!!!!!Voiced by Rena Mizuki in Japanese and Creator/ErinFitzgerald 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.

* TheBaroness: She's about as close as ''Xenosaga'' gets to this trope.
* CreepyChild: In ''Episode II'', at least.
* CurbstompBattle: She beats Canaan in seconds when Yuriev invades the Durandal.
* DaddysLittleVillain: To Yuriev.
%%* DarkActionGirl
* DistaffCounterpart: To the male [=URTVs=]. {{Justified|Trope}} in-universe.
* EarlyBirdCameo: During a brief flashback in ''Episode II''.
%%* EvilRedhead
* NeverASelfMadeWoman: Her dad ''is'' Dimitri Yuriev, after all.
* NinjaMaid: To Yuriev.
* PositiveDiscrimination: Invoked. She claims that females are superior to males, at least theoretically. [[spoiler: Given that Jr. wipes the floor with her, she's wrong.]]
* OppositeSexClone: She was created mostly from Yuriev's X-chromosome and the use of the surrogate mother. Justified, as the female URTVs were needed to preserve the mitochondrial DNA, which is passed from mother to child.
* SheIsAllGrownUp: And killing people.
* UndyingLoyalty: To Yuriev, again.
!!'''Dr. Sellers'''
!!!!!!Voiced by Creator/MasaharuSato in Japanese and Creator/SteveBlum 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.

* ChronicBackstabbingDisorder: It's probably easier to list the people he ''hasn't'' screwed over.
* CoolShades: Described as "motorized sunglasses" in the ''Episode I'' database. They're apparently bolted to his face.
%%* DeadpanSnarker
* TheDragon: To Yuriev in ''Episode III''.
* EarlyBirdCameo: 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''.
* EvilLaugh: Does a little evil chuckle in his last scene.
%%* ForScience
%%* FourEyesZeroSoul
* GeniusCripple: A self-made example. He ruined Joachim Mizrahi's life, so Mizrahi shot his kneecaps off.
* JerkAss: He's mean, rude, inconsiderate and disrespectful.
* {{Kneecapping}}: Mouth off to Joachim Mizrahi, kiss your legs good bye.
%%* MadScientist
* MorallyAmbiguousDoctorate
* NoCelebritiesWereHarmed: He's modeled after freaking Peter Sellers.
* ShoddyKnockoffProduct: He openly admits his life's work is nothing but this, with his inspiration being Mizrahi's works.
%%* SinisterShades
%%* TheUnfought
* WhatHappenedToTheMouse: He's one of the few dangling threads the series left behind, as he's never actually killed on screen.
* YouAreTooLate: 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 Creator/DCDouglas in English.

The black testament, who has some sort of connection with Ziggy.

%%* BaldOfEvil
%%* BlackCloak
* TheCracker: Before he became a supernatural monster he was a ''Franchise/GhostInTheShell''-inspired cyber-terrorist with whom Ziggy tangled during his days as a policeman.
* CurbStompBattle: In ''III'' delivers one to the entire cast [[spoiler: until KOS-MOS reawakens from her repairs after the fight with Telos]].
%%* EnigmaticMinion
* EvilAlbino: Maybe. That or he's just frighteningly pale.
* HollywoodHacking: Famous for this pre-Testament.
* MindOverMatter: His main form of attack;
%%* SerialKiller
* TheStarscream: He wanted Wilhelm's power for himself. [[TheChessmaster Wilhelm saw this coming a mile away]].
* WrongGenreSavvy : He thought that the Compass of Order and Chaos was the source of Wilhelm's power, and thus all he had to do was sneak into his office and [[SchmuckBait take it for himself]]. Too bad not only was the opposite the truth, but Wilhelm is literally the only person who can use it due to the fact that it is used to observe the '''[[TheseAreThingsManWasNotMeantToKnow entire collective subconscious]]''', i.e. the 'overmind' of all humanity. Turns out the reason he just leaves it there is because anyone dumb enough to try taking and/or using it would be [[MindRape Mind Raped]] to death.
!!!!!!Voiced by Mariko Suzuki in Japanese and Creator/BridgetHoffman 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.

* AIIsACrapshoot: T-elos is cruel and sadistic, compared to KOS-MOS's logical indifference or protectiveness.
** This could be more of the below EvilCounterpart. It's not just their personalities that's flipped, but pretty much ''everything'' along with a play on words. KOS-MOS is right-handed (dextrous, implying skill and effectiveness) while T-elos is left (sinister, implying cruelty). Despite that, she never displays any signs that she'll disobey her creator.
* AxCrazy: She's violent and destructive. She makes it clear to Shion that the only reason she survives her encounters is because [[spoiler: Kevin]] gave orders not to kill her, which didn't exclude hurting her.
* {{BFG}}: Her gattling gun.
* CameBackWrong: She's [[spoiler:the forcibly reanimated and cybernetically enhanced corpse of Mary Magdalene. It doesn't get much more ''wrong'' than that. Her mere existence is yet another drop in the bucket of "irredeemable asshole" that is Kevin Winicott]].
* ChekhovsGunman: She was briefly mentioned in Episode I. Actually she WAS planned to make appearance since the first game, but she surfaces in the last game.
* ChestBlaster: Her Phase-Transfer Cannon.

* CurbStompBattle: Delivers a brutal one to [[spoiler: KOS-MOS that leaves her so damaged that repairing her was considered hopeless.]]
* DarkActionGirl: T-ELOS fits this to a [[IncrediblyLamePun T]].
* DarkSkinnedBlonde: Technically white hair.

* EvilCounterpart: To KOS-MOS, although it's a little more complicated than that.

%%* HairAntennae
* HeelFaceTurn: Not in her game, but when she appears in [[VideoGame/EndlessFrontier other]] [[VideoGame/ProjectXZone games]] with KOS-MOS, T-elos usually wounds up in an EnemyMine situation OR TheOnlyOneAllowedToDefeatYou, so she teams up with KOS-MOS. Her characterization as a Face is mostly a high caliber {{Tsundere}}.
* HiddenEyes: When her headgear covers her eyes at the party's first meeting with her.
* HollywoodCyborg: Unlike KOS-MOS, who is a robot powered by [[spoiler: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]].
* HyperspaceArsenal: Like KOS-MOS.
%%* IcyBlueEyes
* LackOfEmpathy: Even more so than KOS-MOS in Episode I as KOS-MOS acts as she was commanded. The scary part is that T-elos emotes much more than KOS-MOS.
* LargeHam[=/=]EvilIsHammy: Quite.
