!Main Characters

!!Vincent Law / [[spoiler: Ergo Proxy]]
->Voiced by Creator/KojiYusa (JP), Creator/LiamOBrien (EN)
Vincent Law is one of the main characters of the anime. At the beginning of the series Vincent is portrayed as a unimpressive immigrant technician from Mosk whose main goal is becoming a "Fellow Citizen" of the utopian city Romdeau. Vincent is forced into exile from Romdeau following criminal accusations into the desolate tundra of post-apocalyptic Earth. During the series he is joined by the child "Auto-Reive" Pino and the Intelligence Bureau investigator Re-L Mayer to uncover his past and his relationship to the titular Ergo Proxy. [[spoiler: [[TomatoInTheMirror Turns out he IS Ergo Proxy]], a clone of Proxy One created as a proxy resistant to UV light, and creator of Romdeau. However, he is later dissatisfied with his status as an incomplete proxy with incomplete tasks and leaves all of his duties to a man named Donov Mayer - Re-l's grandfather. He leaves to live with Monad Proxy, who was governing Mosk at the time. After his leave, Proxy One was angry at Monad due to the fact that she effectively stole his "instrument of death against the progenitors". Monad took Ergo's memories out of love for him, losing her sanity as a result. From the loss of Ergo's memories became Vincent Law, a human who had little recollection of his past outside of being from Mosk and moving to Romdeau to live a normal life. However, when Monad ends up in Romdeau, chasing Vincent trying to kill him as a result of the Pulse of the Awakening, Vincent unconsciously becomes Ergo Proxy once more and sets the story in motion.]]
[[caption-width-right:350:Vincent Law]]
* AchillesHeel: [[spoiler: As a Proxy, Vincent is essentially indestructible to all forms of damage. There are really only only one thing that can kill a Proxy: [[KryptoniteRing FP bullets]].]] [[spoiler: But, given that Ergo Proxy was designed by Proxy One to be immune to the Pulse of the Awakening (UV radiation), it is entirely plausible that Vincent is also immune to the FP rounds.]]
* [[spoiler: AmnesiacGod]]
* AnguishedDeclarationOfLove: To Re-l Mayer.
* AntiHero: He starts off as a weak-willed, low-status immigrant just trying to make good for himself.[[spoiler: While in his Ergo Proxy form, Vincent is a {{Berserker}} that seemingly has zero inhibitions.]]
* [[spoiler: AntiAntichrist]]:
* BadassCreed: Are the last lines of the series, but damn - it's a badass way to close a series.
--> '''Vincent''': "[[spoiler: I am Ergo Proxy - the agent of death.]]"
* BecomeARealBoy: Like Pino in this respect [[spoiler: and also why he hopefully will also survive on contact with sunlight]].
* BewareTheNiceOnes: Vincent is even tempered, generous and kind to almost everyone he meets, until you threaten him or Pino.
* BerserkerTears: [[spoiler: Vincent is prone to these while in Proxy form. Usually while killing another Proxy.]]
* BookDumb: Vincent is terrible at trivia. Possibly FridgeBrilliance, considering [[spoiler: his [[LaserGuidedAmnesia self-imposed memory problems.]]]]
* BrokenTears: Several times over the course of the series. [[spoiler:Most notable is when Vincent is lying on the ground weeping after Proxy One forces him to face the fact that he is a Proxy.]]
* BungledSuicide: [[spoiler: Vincent attempts this by jumping from the dome exhaust pipe after being accused of treason, ending his goal of becoming a "fellow citizen".]]
* TheChosenOne: Hoody said that Vincent was this to the rest of the commune dwellers when they started to suspect him. [[spoiler: Then it ended up sort of being true...]]
* DarkAndTroubledPast: [[spoiler: As Ergo Proxy he constructed the Romdeau Dome only to abandon it to live with his lover, Monad Proxy.]]
* {{Determinator}}
* [[spoiler: DodgeTheBullet]]: [[spoiler: In Proxy form.]]
* DoomMagnet: Picks up on this before the reveal. [[spoiler: Well, he is the [[PersonOfMassDestruction agent of death]].]]
--> '''Vincent''': "[[spoiler: Am I the Angel of Death? Everything I touch stains with blood. Everyone around me dies.]]"
* TheDrifter: [[spoiler: During the middle section of the series Vincent travels the wastes with his sole synthetic companion Pino]]
* EyesAlwaysShut: Starts out this way, but they open after he becomes less meek.
* FanservicePack: Over the course of the series, he gets better looking and even seems to grow several inches taller.
* [[spoiler: GlowingEyesOfDoom]]: [[spoiler:As Ergo Proxy]]
* GreenEyes: [[spoiler:When he finally opens them in episode three.]]
* HorrifyingHero: [[spoiler: As Ergo Proxy he is often referred to as "a monster".]]
* InnocentCohabitation: With Re-L onboard the 400 Rabbits.
* [[spoiler: ItSucksToBeTheChosenOne]]: [[spoiler: Vincent has the habit of getting everyone he cares about killed, since he is the agent of death.]]
* TheKirk: To Re-L's Spock and Pino's Mccoy.
* [[spoiler: JekyllAndHyde]]: [[spoiler:Initially, Ergo Proxy comes across as his SuperpoweredEvilSide and is a distinct entity from the meek Vincent.]]
* MeaningfulName: "Vincent" derives from the Latin word "Vincere", to win.
* NiceGuy: Vincent is pretty much a overall decent person wanting to help everyone from infected Autoreivs to snarky goth girls.
* NonActionGuy: Subverted. Initially Vincent is portrayed as weak, submissive and incompetent as a foil to Re-L's ActionGirl. But, in moments of danger Vincent is able to gather the courage to defend his friends using his impressive GunFu. [[spoiler: When it is finally revealed that Vincent is a Proxy he gets upgraded to full Action Guy.]]
* PapaWolf: Do NOT mess with Pino. Seriously, don't.

* ScrewDestiny: [[spoiler: Vincent decides to continue to live in the world after the re-population of the earth, despite the fact that Proxies are now no longer useful and will be killed when exposed to sunlight. However, as a proxy created by Proxy One to withstand the weakness of UV light, he has no real way to die as a result of the sunlight.]]
* [[spoiler: SuperpowerLottery]]: [[spoiler:Ergo Proxy is essentially a demi-god possessing SuperStrength, SuperSpeed, NighInvulnerability, {{Shapeshifting}}, and {{Immortality}}.]]
* StalkerWithACrush: Doubly subverted. [[spoiler: During the second episode the Intelligence Bureau attempts to convince Re-L that she was attacked by a stalker rather than a "monster". The investigators further try to guide her into placing the blame on the poor immigrant Vincent Law. By episode three it's revealed that is was in fact Vincent who was stalking her in the form of Ergo Proxy.]]
* SurvivorGuilt: [[spoiler: Vincent is indirectly responsible for getting the entire population of The Commune killed.]]
* TookALevelInBadass: Several, even!
* TurnedAgainstTheirMasters: [[spoiler: Implied in the series finale. Vincent, having finally reconciled between his split personalities, watches as the source of most of his misery, The Creators, return to Earth. The look on his face says it all: he's about to kick some serious ass.]]
* WalkingSpoiler: Where to even begin? [[spoiler: Not only is he actually a proxy, but he's not even an original proxy. He was also created by Proxy One in his own image to create Romdeau out of spite for the creators. Vincent himself is an entirely separate persona made by Ergo Proxy as a means to forget his true nature and live in peace. Oh, and the proxy he killed in the very first episode in Re-L's apartment? Monad Proxy, who he was originally in love with prior to the Pulse of the Awakening.]]
* WhatTheHellHero: Can do some rather questionable things [[spoiler: as Ergo Proxy, though often they are justified.]]

!!'''Re-L Meyer'''

->Voiced by Rie Saito (JP), [[Creator/MeganHollingshead Karen Thompson]] (EN)
Re-L is a Intelligence Bureau investigator tasked with locating and destroying Cogito infected AutoReivs. One night after leaving an ongoing investigation she is confronted by a "monster" in her apartment. After this event she is caught in a net of conspiracies around the Cogito Virus, the Domed Cities and the mysterious "Proxies". While investigating she joins with the exiled Vincent Law and self aware AutoReiv Pino to expose the truth.

[[caption-width-right:350:Re-l Mayer]]
* ActionGirl: Takes down infected Autoreivs with her signature shotgun, [[spoiler: She's even able to kill a Proxy with an FP bullet at one point.]]
* [[spoiler: AmbiguouslyHuman]]: [[spoiler:It is subtly implied throughout the series that Re-l may not be human, but a imperfect clone of Monad Proxy, which would explain Vincent's inherent attraction to her.]]
* AntiHero: She's a bit cold emotionally and has a definite mean streak, but there's no question she's one of the good guys.
* ArbitrarySkepticism: [[spoiler: She refuses to believe that Vincent is a Proxy until witnessing his transformation firsthand.]]
* BadassLongcoat: Arguably subverted; despite her competence at her job, she's nowhere near as badass as she presents herself, a fact that becomes apparent [[spoiler: after leaving Romdeau. This is bitterly lampshaded by Iggy after he contracts the Cogito virus, when he [[TheReasonYouSuckSpeech calls her out]] on acting like a badass government agent when she's really kind of a spoiled brat. Just how accurate this is is ambiguous, however; it could just be the rantings of a wounded friend taken for granted for too long.]] And despite all that, she still remains tough as nails throughout ensuing events.
* BelligerentSexualTension: With Vincent Law.
* BadassNormal: [[spoiler: She is the Batman to Vincent's Superman.]]
* BilingualBonus: Her Name is spoken like the german word "Reell", meaning "Real" or "Really existing". Although the word "Reell" in german is rarely used outside of the context of Mathematics.
* {{The Comically Serious}}
* DeadpanSnarker
* DecoyProtagonist: [[spoiler:Re-L is initially portrayed as the protagonist of the series by most of the promotional material, by episode four she is demoted to SupportingProtagonist.]]
* DefrostingIceQueen: Hell of a slow thaw, though.
* EeriePaleSkinnedBrunette: Everyone else has normal skin tones, whereas Re-l is straight black and white.
* EmotionlessGirl: mild example, she has the tendency to be angered easily.
* {{Good is Not Nice}}: Vincent is well aware of this.
* {{Goth}}: She's something of a [[DeadpanSnarker snarky]], gloomy goth, dressing in all black and wearing lots of eyeshadow.
* ExcessiveEvilEyeshadow: Re-l isn't evil, but you couldn't tell that by looking at her.
* HotBlooded: Especially when compared to the rest of the citizens of Romdo.
* IcyBlueEyes: Her pale blue eyes compliment her{{goth}} aesthetic.
* IntelligenceEqualsIsolation: She chafes at Romdeau, where much of the human population are so coddled and helpless that they're effectively automata.
* FakingTheDead: [[spoiler: Re-l fakes her death at the hands of Cogito infected Autoreivs, so that she can sneak out of Romdeau to pursue Vincent and uncover his connection with the Proxies.]]
* GreatDetective: Re-L works as a detective of the Romdeau Intelligence Bureau.
* JerkWithAHeartOfGold: She initially comes off as cold and arrogant, especially towards Vincent, but goes out of her way to rescue him.
* KissOfDistraction: She uses this on Vincent to distract him from the pistol loaded with [[spoiler: Proxy killing FP bullets]]
* MasculineGirlFeminineBoy: Re-L to Vincent.
* MercyKill: [[spoiler: She kills the decapitated Cogito infected Iggy.]]
* MsFanservice: Not as much as other female characters in anime, but is particularly prominent when [[spoiler:Ergo Proxy has flashbacks of their first meeting in her bathroom.]]
** Of course, given that [[spoiler: the flashback is from his POV, it's combined with MaleGaze.]]
* {{Nepotism}}: Since her grandfather is the Regent Re-L is given a great deal more liberty than you're average citizen, [[spoiler: that is until her grandfather decides she's disobeyed him too many times and decides to have her assassinated.]]
* ReincarnationRomance: [[spoiler: It is strongly implied that Re-L is some form of clone of Monad Proxy, Ergo Proxy's deceased lover. This explains why Ergo Proxy first confronts Re-L in her apartment.]]
* RuleAbidingRebel: All Re-L does is complain about the monotony of her dystopian city, but does nothing to change it.
* ScrewTheRulesImDoingWhatsRight: Re-L ignores her orders to end her investigation of the Proxies.
* SeekerArchetype: Re-l becomes obsessed with uncovering the nature of Proxies to the point that she is willing to discard her previous life.
* TheSpock: Re-L is rational and skeptical, playing off of Pino's childlike naivety.
* SpoiledBrat: She's the granddaughter of the regent and she has no qualms about using it to her advantage.
* SuperOCD: It's been speculated that Re-l might have OCD, judging from the way she conducted an earlier investigation of Vincent's room (she lined up a cup on a stand in the mirror image of another) and the way that she behaved in episode 16. However, the former case could be the result of years of strict government training and the latter a result of CabinFever.
* SweetTooth: She has a thing for ginger ale.
* {{Tsundere}}: towards Vincent Law. At the beginning of the series she doesn't pay any attention to the lowly immigrant, [[spoiler: once she learns his true nature o she frequently abuses him by to test the extent of his power.]]
* UnresolvedSexualTension: Towards Vincent Law
* UsedToBeASweetKid: Judging from some old videos from Daedalus, Re-l seemed to be pretty cheerful growing up. Then she just became... [[{{Goth}} gloomy.]]
* WeaponOfChoice: Her signature pump-action shotgun.
* [[WellDoneSonGuy "Well Done, Granddaughter" Girl]]: In the end, Re-l just wants her grandfather's love and recognition.
* WhenSheSmiles: At the end of episode 16, upon seeing Re-l give a true smile, Vincent is seen blushing.

->Voiced by Creator/AkikoYajima (JP), Rachel Hirschfeld (EN)
Pino is one of the three main characters of Ergo Proxy. Pino is a "companion-type AutoReive" designed to act as a surrogate daughter to residents of Romdeau who are prohibited from rearing children, in her case Raul Creed and his wife. During the course of the show Pino becomes infected with the Cogito Virus which gives her a consciousness and full range of emotions, as such Pino often behaves like a normal (if not hyperactive) young girl.

* [[BecomeARealBoy Become A Real Girl]]: See MeaningfulName. It's kind of implied that this does happen in a literal sense, and it's necessary for the series to have a happy ending of any kind [[spoiler: as otherwise, she'd be killed by ultraviolet light like all autoreives]].
* CheerfulChild: Throughout the series she's always optimistic regardless of the situation.
* CreepyChild: Before Character Development.
* CuriousAsAMonkey
* TheMcCoy: She is childish and emotional in contrast to Re-L's stoic rationalism.
* MeaningfulName: She shares a name with Pino of ''Manga/BlackJack'', and for both of them the name alludes to Literature/{{Pinocchio}} and their status as an artificial child.
* PleaseWakeUp: [[spoiler: Can't understand that her friend Timothy has died.]]
* ThePollyanna:
* RobotGirl: She is a companion AutoReiv designed to be a couples surrogate child.


->Voiced by Kiyomitsu Mizuuchi (JP), Creator/TravisWillingham (EN)
Iggy is a supporting character within the series. Iggy is Re-L's loyal robotic entourage who acts as a personal assistant when she works as an inspector with the Bureau of Intelligence.
* AIIsACrapshoot: [[spoiler: DoubleSubverted. He gets infected with the Cogito virus when [[OffingTheOffspring Romdeau's ruler sics his Autoreivs on Re-L,]] but actually keeps his sanity for a time. Then Re-L orders him to go back to Romdeau on his own, [[SanitySlippage at which point it kicks in for real.]]]]
* [[spoiler: AlasPoorScrappy]]: [[spoiler: InUniverse. Re-L clearly doesn't like being around him for much of his screentime, on account of believing him to be JustAMachine and her [[ArchnemesisDad grandfather's spy.]] It's only after [[WhatTheHellHero he rails on her]] [[AIIsACrapshoot under the effects of the Cogito virus,]] and has to [[ICannotSelfTerminate be put down]] [[DeathEqualsRedemption after saving her life]] that she shows any sincere affection towards him.]]
* [[AmbiguouslyGay Ambiguously Gay.]] Later episodes reveal that Re-l deliberately chose him to sound this way.
* JekyllAndHyde: [[spoiler: [[ICannotSelfTerminate As he lays dying in Re-L's lap,]] he continually shifts between his [[NiceGuy old personality,]] who [[TearJerker begs Re-L to forgive]] [[MyGodWhatHaveIDone him and not to hate him,]] and his [[{{Jerkass}} Cogito]] [[{{Yandere}} infected]] [[MoodSwinger self,]] who angrily [[NeverMyFault blames her for getting him killed.]] The possible implication being that even after developing sentience, it was the [[GollumMadeMeDoIt Cogito infection causing him to attempt his kidnapping and murder]] [[TragicMonster not Iggy]]]]
* JerkassHasAPoint: [[spoiler: Subverted. [[SanitySlippage After completely losing it,]] he chews out [[WhatTheHellHero Re-L essentially for thinking herself more Badass than she really is]], but whether one agrees with him or not, his "plan" [[WhatAnIdiot (consisting of dragging Re-L back to Romdeau, where she'll likely be arrested and/or executed,]] [[ItCanThink and he'll likely be decomissioned for being infected)]] [[StepThreeProfit is so unbelievably half-baked,]] that his only response is to ignore Re-L for calling him out on it. [[MoralEventHorizon And that's not even getting into]] [[MurderTheHypotenuse trying to kill Vincent]] to keep Re-L for himself, basically decimating whatever point he could possibly have.]]
* [[spoiler: KilledOffForReal]]: After [[spoiler: Re-l performs a MercyKill.]]
* NiceGuy: [[{{Camp}} Peppy]], supporting, optimistic, and [[BigBrotherInstinct protective]], hard to see why [[JerkWithAHeartOfGold Re-L dislikes him at first.]] [[spoiler: [[AIIsACrapshoot Until]] [[SanitySlippage later]] [[TookALevelInJerkass that is.]]]]
* StraightGay: Or at the very least "Asexual Gay".
* TheWatson: Iggy acts as this to Re-L during her time as a inspector.
* {{Yandere}}: Becomes this later in the series [[spoiler: after getting the Cogito Virus]].

!!'''Raul Creed'''
->Voiced by Hikaru Hanada (JP), Creator/PatrickSeitz (EN)
Raul Creed is the newly appointed Director-General of the Citizen Security Bureau, who reports directly to the Regent . He and his wife took Pino as a surrogate child prior to the beginning of the series. [[spoiler: Initially loyal to the system, he comes to despise the ruling order responsible for the city's slow decay and lashes out destructively. With this is his despising of Vincent Law, whom he blames for killing his wife and infant child during Vincent's chase with Monad early in the series.]]
* AntiHero / AntiVillain: Depending on your interpretation of him. He means well. Really.
* AxCrazy: [[spoiler:Post SanitySlippage.]]
* BadassLongcoat: Almost always wearing one. As for badass, he proves to be pretty amazing at fighting Autoreivs and hiding himself when he needs to.
* {{Break the Haughty}}
* DaChief: He is the director of the Security Bureau, thus putting him completely above Vince and almost above Re-L in terms of prestige.
* DarkMessiah: Becomes this to the human residents of Romdeau, after the autoriev situation goes out of control. It ends with a 90 percent of the population dying. Not that there were any better options once the proxies dissapear.
* DeadpanSnarker: Not to Re-L's extent, but he has his moments. The best one might be when he flatly calls out the Regent on how pretentious is to call a missile weapon "Rapture".
* DeerInTheHeadlights: As he sees his wife and recent born adopted son getting killed in front of his eyes, Raul just keeps staring with a blank expression. At first it appears to be a case of [[DissonantSerenity him being stoic]], but then we learn that it was probably an awfully repressed shock.
* {{Determinator}}: Once Vincent leaves Romdeau, Raul becomes hell-bent on capturing him and bringing him to justice.
* DoNotGoGentle: He is decided to go fighting, trying his best to overcome the new humans faults and to live in a world without proxies. Sadly for him, his efforts are misguided thanks to his hate for Vincent/Ergo.
* {{Even Evil Has Standards}}: [[spoiler: Even after he goes insane, Raul finds Daedalus' attempts to clone Re-L for his own purposes to be utterly disgusting]].
* RogueAgent: For a while, thanks to calling the Regent out on his attitude. However is soon obvious Romdeau has gone to shit In such a way that the Regent prefers to put Raul in the position again. Not that it helps anyone.
* GreenEyedMonster: Fatherly version. He was obviously jealous of seeing Pino treat Vincent like a father/older brother figure. And part of his return to sanity begins once he realizes Pino had actually been thinking and drawing him too, which makes him drop his quest to save Romdeau in an attempt to get to see her one last time.
* InspectorJavert: Shades of it anyway.
* ItsPersonal: [[spoiler: Blames Vincent Law for the death of his wife and infant son.]]
* [[spoiler: KilledOffForReal]]: [[spoiler: Real/Monad mortally wounds him when he tells her he is gonna kill Vince. After that he just regains his composture and wanders looking for his daughter. He doesnt get to see her, although his feelings will probably reach her thanks to Kristeva.]]
* LaughingMad: When shooting Proxy One (whom he believes to be Ergo) in the arm.
* NietzscheWannabe: Definitely becomes more of a nihilist post-SanitySlippage
* NeverGotToSayGoodbye: [[spoiler: To his surrogate Autoreive daughter Pino. However he did entrust Kristeva with protecting her.]]
* SanitySlippage: The death of his family and the certain doom of the city he was put on charge of eventually take a toll on his sanity. He recovers far too late.
* SpannerInTheWorks: Tries to be this for Vince and Re-L out of spite for the former. Eventually he doesn't succeed, but not for the reasons one would expect. Their journey was more important than the destination.
* {{Tall Dark and Snarky}}: Quite a lot.
* TheStoic: Until [[spoiler: he goes [[Main/{{AxCrazy}} completely insane]]. ]]
* WellIntentionedExtremist: Starts as this. [[spoiler: [[MotiveDecay Descends into a]] WoobieDestroyerOfWorlds, before [[HeelRealization coming to his senses]] [[AlasPoorVillain in his final moments.]]]]

[[spoiler: In the final episodes, Daedalus has been revealed to have created a fake Re-l as a replacement for the Re-l, who has become obsessed with Vincent Law causing Daedalus to feel rejected. He also has shown that he has cracked-up mentally and that he no longer cares what happens to the world. Daedalus, concluding that Re-l has always left him behind, and is later crushed by falling rubble during the collapse of the dome of Romdo.

* [[spoiler: KillThemAll]]: [[spoiler: After he just stops caring about what happens to the world.]]
* OlderThanHeLooks: Could easily pass for a young teenager. [[ViewerGenderConfusion Some viewers tend to mistake his gender as well]].

Proxy One essentially decided "Fuck that", and instead rejected their plans and ideals, opting to create a proxy who could survive sunlight i.e. Ergo Proxy, both to ensure at least one Proxy survived the genocide, and as a big, fat screw you to the Creators.]]

* MysticalWhiteHair: She has this.

* ThisIsUnforgivable: Once he realizes Vince has abandoned his memories as a proxy, he loses his shit and tries to murder him, considering him a traitor the their cause.
* UnholyMatrimony: With Senex Proxy.

!!Bookstore Proxy

* CoolOldGuy: Appeared as an old Librarian.

!!Cave Proxy

* TheBrute: Whatever he was before, he is now reduced to a giant, grunting abomination of a man.

* TheVoiceless: Doesn't speak.
* NoNameGiven: Like many others.
* ItCanThink: Iggy ultimately notices that he was guarding Womb Machines similar to the ones in Romdeau. Its implied he used to take care of his city a long time ago like the average Proxy, until something happened that made he lose his sanity.

!!Doppelganger Proxy

* AxeCrazy: The guy is a real piece of work, as you can see. He murdered literally everyone in town and buried them in the local lake.
* Doppelganger: What he is. His true, original shape has been lost in time and now he just assumes the form of whoever he wants.
* DrivenToSuicide: He tries to kill himself along with Vince as to not be lonely.
* IdentityImpersonator: Takes on Vince´s and Re-L identities and it outright says that he took on every citizen identity at some point in an effort to be loved.
* IJustWantToBeLoved: His motivation.
* KillAllHumans: He killed everyone on his Dome, because he didnt feel loved by them.

* MissingReflection: He does not reflect on the water.
* NoNameGiven: Remains unnamed like several other Proxies.
* TakingYouWithMe: See above.

!! MCQ

* TheAnnouncer: For his own show.
* GracefulLoser: Has zero problem with dying and even seems cheerful Vince defeated him in the quiz match. It is also implied he was seeking death as of hearing the Pulse Of Awakening.
* LargeHamAnnouncer: Verily so, fitting for the kind of show he leads.
* DissonantSerenity: Rather unfazed when proclaiming he is about to die.
* {{Catchphrase}}: "Q-Q-Q-Q!"
* NonActionGuy: Engages Vince in a quiz match, instead of a outright battle.
* SlaveToPR: Definitively. The guy is just about to die, but still takes time to call his viewers, joke around, give orders to the camera men, etc.
* YouGottaHaveBlueHair: Purple hair.
* MrExposition: Thanks to him, we get a lot of data about the world the characters are living in and the story. In fact, the chapter he appears on is rather important to get it all correctly.
* KnowledgeBroker: While most Proxies are implied to know about everything, he even seems to know about Vince´s story and even Proxy One.

!!Will B. Good

* {{Catchphrase}}: Fittingly, "Good!".
* MysteriousMiddleInitial: We never get to know what the B. stands for.
* {{Expy}}: Of Walt Disney, complete with his own theme park and cartoon creations.
* TheCreator: His creations call him this. And indeed he creates a lot.
* MediumBlending: He appears entirely white and black and in old style film animation.
* BreadAndCircuses: His motto. He is trying to make the humans of his dome as happy as they can be before they eventually die out like the original humans in space designed.
* AntiVillain: Probably one of the nicest Proxies out there, if a little coward.
* RedBaron: The Creator.
* SuperFunHappyThingOfDoom: Smile Land is this, although its not entirely his fault as the people from the Domes were intended to die in the first place. He just decided that, since that is inevitable, he wants to let them die while experiencing all kinds of joy and bliss.
* LovableCoward: A good guy no matter how you see it, and he is terrified of Ergo Proxy since he knows once they meet one of them is gonna die -and it will be definitively be him-. As so, he tries to get on Pino good side to get her to spew out what is Ergo´s weakness. It doesnt work. Asking her to ask Vince to avoid his city however does.
* TheSvengali: The guy tries, but thanks to a probable Cogito infection his creations easily turn against him and beat him.
* NonActionGuy: Clearly not a fighter, as Autoreivs made for entertaining children manage to beat him up. That said, his planning and his will manage to save his Dome from destruction, if only he did that to make his humans happy.
