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 the main protagonist of the series.
Ace Pilot: Arguably, but she piloted E.S. Dinah Filia together with Miyuki in the beginning of Episode III.
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.
All-Loving Hero: Not so very much if you think about her relationship with Jin.
Fanservice Pack: Her outfits grow more fanservice-y in each episode, culminating in an exposed midriff, shorts and Zettai Ryouiki in episode III.
Fear of Thunder: Understandable, since her nanny, parents, and lover were all brutally killed in front of her during two different thunderstorms.
Feminine Women Can Cook: 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.
Flower Motif: Not the character, but her name. Soraya Saga says that every female character in the party was intended to have flower motif names.
Heroic BSOD: After finding out she's the one who called the Gnosis into the real number domain and summoned Abel's Ark.
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.
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 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. This was mostly accomplished by Kevin hand-picking her to be his Number Two, and then committing his Thanatos Gambit, leaving her as his successor by default.
It's All About Me: Hoo boy, she has a big one. 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 "World of Cardboard" Speech to snap out of it.
Magitek: Shion's special attacks apparently use an "Ether Circuit."
Memento MacGuffin: The pendant that she's wearing belonged to Kevin's mom who's already passed away. Turns out, the pendant is the Key that Wilhelm searched for.
Mini Dress Of Power: Her Vector uniform in Episode I. It returns as an alternate outfit in III.
Ms. Fanservice: There's one cutscene in Episode III which views her with full blown swimsuit wear.
Never a Self-Made Woman: 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. Justified since it was all part of Wilhelm's Thanatos Gambit.
Nice Girl: Mostly, but when it comes to Jin sometimes she's this (dere-rere mode on) sometimes she's in her tsun-tsun mode.
No Social Skills: 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.
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 occurred.
Took a Level in Jerkass: In Episode III, although mostly out of reaction to 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.
Trauma Conga Line: HOLY SHIT does she go through a big one in Episode III. 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.
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.
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. Specially obvious in her fourth frame, in which her breast size is increased a couple of cup sizes.
Determinator: She's always great when it comes to critical situation. But some times she'll still lose.
Died Happily Ever After: In the end of Episode III, she was left floating in the space with a dismembered right arm and both of her legs. According to the spoileriffic (so he draws it carefully) promotion artwork by CHOCO, she was seen to be reunited with Shion (Maiden of Mary, to be precise).
Do Any Thing Robot: When it comes to weapons, story wise, if they exist, she can use them.
Genre Savvy: For most of the time. Including she knew that Matthews might be rushing the Elsa away unless she warns him that if he does so, she'll explode the machine, and the same goes with the entire spacecraft.
Girlish Pigtails: In her 4th form early design, CHOCO mistakenly draws her with these.
Hyperspace Arsenal: Justified since she uses U.M.N transport to access her arsenal, most of which is ridiculously huge.
Innocent Blue Eyes: Appeared two times throughout the series. These eyes appear only in critical situations where she must save Shion. It was Mary Magdelene's will who's resided within her and sometimes awoke.
In the Back: When she delivers the final strike to Voyager.
Knife Nut: In her 4th form, she has this beside her left foot. She uses this to finish T-elos who's paralyzed because of the Phase Transfer Cannon's attack.
Lack of Empathy: In Episode I when Shion protests for her lack of conscience by killing Virgil just because he was on her line of fire, she simply answers that of all people Shion should knew that she is merely a weapon, not a human being.
Techno Babble: Every time she informs something about their current location or the enemy, specifically about her current condition.
The Cameo: She appears in many other Namco's (or involved) games.
She appears together with Shion and MOMO in Namco X Capcom.
She appears in Super Robot Taisen OG: Endless Frontier, alongside T-elos. Also in its sequel.
Her costume can be made in Soul Calibur III and Tales of the World Nakiri Dungeon 3.
Her costume appears as DLC costume for Judith in the PS3 version.
Appears as a support character in Tales of Hearts.
Appears with T-elos (again) in Project X Zone.
The Quiet One: For most of the time, she'll not talk unless someone started the conversation first.
The Worf Effect: Got subject to this in III against Ω Res Novae, with even X-Buster that wiped out a planet's worth of Gnosis, had no effect on it, and later against T-elos fails to even scratch her and gets an even worse beating than she did from Ω Res Novae.
To Become Human: It was Kevin's desire to make her human. Well, she made it in Episode III with Mary's will inside her.
To a lesser degree, Shion just wants her to understand human's emotions.
Took a Level in Badass: As if she wasn't nearly at the badass level cap to begin with, her receation using Erde Kaiser parts coupled with her "awakening" brought her from being roughly 1/5 as powerful as T-elos to such a level of badass that she defeated her one-time destroyer seemingly without effort.
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.
A God I Am Not: He has the "power of God" which is Anima, but he didn't use it for God-wannabe schemes.
Ace Pilot: Piloted E.S. Asher together with Canaan 14 years ago during the Miltia War.
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.
Ambiguously Human: For most of the series, it's unclear what he is. Turns out he's not human.
Apocalypse Maiden: He was this once, until Mary sacrifices herself to divide his power into 12 vessels of Anima.
Apologetic Attacker: In Episode II if you execute his Heaven's Wrath sometimes he'll say "sorry".
Badass: Read the spoilers, if you dare to spoil yourself.
Bash Brothers: With Jin. They both even have their own Double skill at the beginning of Episode II. This also happens in the anime version.
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.
Big Damn Heroes: In the ending of Episode I when KOS-MOS once again pulls another crazy Heroic Sacrifice moment to save the Elsa from being burned in the atmosphere, he opens Abel's Ark that ends up saving everyone.
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 Domains 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 resides, meaning, the Lower Domain is sacrificed to save the Upper Domain.
Jack-of-All-Trades: When he worked on Elsa, he had several roles in the airship and he also did things other than his job.
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.
Made of Iron: Inside the E.S. Asher when Canaan impressed and told chaos that anyone should be passed out by his maneuver attack.
chaos: "It's true. You really are as good as they say."
Canaan: "How are you handling the feedback?"
Canaan: "You know, a normal person would've probably passed out by now."
Meaningful Name: Plus points for Fridge Brilliance. His name has a point in one of Jesus's sayings that He came not to bring peace but to torn/seperate the believers and the non-believers.
"I want to believe in the existence of order born from discord."
Offscreen Teleportation: He can teleport. He did it twice on the Elsa in Episode I when he made his first appearance and after he bids good night to the sleeping KOS-MOS inside her sleeping pod. KOS-MOS was the only one in the entire series who noticed this.
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.
Also shares some physical traits and backstory with Seven of Nine from Star Trek: Voyager (blonde haired, blue-eyed person turned into a cyborg against their will slowly regaining their humanity). They even have the same hairstyle.
Guys Smash, Girls Shoot: 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 BFGs, just like KOS-MOS.
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.
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.
Ace Pilot: 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.
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.
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.
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.
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.
Tomboy and Girly Girl: She's more girly than Sakura who Jr. mentioned to be more tomboy, according to Juli Mizrahi.
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 is 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.
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 Fatima.
Really 700 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.
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.
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.
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.
Flanderization: She suffers from this horribly in the third game, turning her into a Butt Monkeyditz with everyone showing little faith in her doing ANYTHING right and treating her pretty horrible as a result, especially by Shion.
Out of Focus: 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.
Orcus on His Throne: 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. Justified in that Vector apparently has a kill-on-sight order on her.
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.
Bitch in Sheep's Clothing: He's initially presented to the player as an otherwise upstanding guy who became the innocent victim of circumstance. Hints about his dark side start slipping out as the series progresses until the vernier of likeability is torn clean off halfway through Episode III and you see what a completely messed up domineering creep he really is.
The Dog Bites Back: He betrays Wilhelm only when the guy starts to tell him how much he failed at his role in his Evil Plan 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.
Jerkass: 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 he's a rude smug asshole.
Yandere: Towards Shion he's trying to save her, but he's willing to kill anybody who gets his way, or at least sees as in his way, even if they're getting in his way because his plan to save her is making her suffer.
Rank Lieutenant. He is a A.G.W.S. pilot stationed on the Woglinde and a veteran of the Miltian Conflict. A Jerk Ass 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.
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 insanethrough 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 FeiExpy 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.
Blue and Orange Morality: 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.
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 Story: Subverted. It's simply a completely alien existence from a higher dimension. And it's curious about humans in a scientific way.
God Is Flawed: A benign entity who wants to do good, but coming into contact with it tends to have very bad side effects.
God Is Good: Despite being an Eldritch Abomination who has difficulty understanding human morality, it wants to understand humans and wants to do good. But God Is Flawed, and its actions cause harm and it doesn't even realize it.
Ax-Crazy: And then some. (Even Margulis is is disturbed by him). 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 loosest 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.
Bilingual Bonus: He makes a 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."
Black Cloak: Although it is technically white, the usage and effect is the same.
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 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 Mind Rape scene is this in spades.
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.
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 entity.
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 can actually neutralize U-DO's waves. Albedo would prefer getting killed than watch his brothers, mainly Jr, die.
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.
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.
Woobie, Destroyer of Worlds: He started to get unhinged learning that everybody he'd either spend life along or watching everybody he knew die of old age. Then he came into contact with U-DO, and what's worse, Jr. paniced and left him and the other URT Vs to it.
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.
Even Evil Has Standards: 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."
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.
Flash Step: Displays the when fighting Jin and also in a flashback with Cherenkov when the two first met when dodging an attack from him and then knocking him with a karate chop.
Gray and Gray Morality: Margulis is not strictly evil, and his greivences with the Federation are legitimate, especially the destruction of Michtam.
Persona Non Grata: Originally a colonel in the Federation military (hence the Bad Ass Long Coat 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.
Utopia Justifies the Means: He dispasionately destroys (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 finding some way to return to Lost Jerusalem.
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: Sees Jin as one and despite the hostility between them does respect him.
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.
Earth-Shattering 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.
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.
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.
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.
Agony Beam: One of the few 'offensive' powers we see him using, which Shion was on the receiving end of.
Determinator: So it will take several thousand years of manipulating mankind to achieve Eternal Recurrence? No sweat. It's not like he hasn't done it before or anything.
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.
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 Rule of Funny/Cool.
Foil: To chaos (the person). And to a lesser extent, Mary Magdalene.
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: He prefers not to get his own hands dirty, but if he needs somebody offed, he's more than willing to sic a Testament on them.
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.
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. Supplementary material suggests not only has he been around since the birth of the universe, he's been going around the Stable Time Loop 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.
The Übermensch: 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.
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").

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.
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.

The black testament, who has some sort of connection with Ziggy.
Stupid Evil: 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 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 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 Mind Raped to death.
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.
This could be more of the below Evil Counterpart. 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.
Ax-Crazy: She's violent and destructive. She makes it clear to Shion that the only reason she survives her encounters is because Kevin gave orders not to kill her, which didn't exclude hurting her.
Badass: Defeats all the protagonists on her own in their first encounter, and the second, only KOS-MOS is able to stop her.
Came Back Wrong: She's 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.
Chekhov's Gunman: 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.
Hidden Eyes: When her headgear covers her eyes at the party's first meeting with her.
Hollywood Cyborg: 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.
Nigh Invulnerable: Gets through the first encounter without a scratch on her, and in the second, the only time she reasct to getting hit by anything is when she's blasted KOS-MOS's own Phase Transfer Cannon.
