!!Mitochondria Eve
[[caption-width-right:214:How the second Eve appears in ''VideoGame/ParasiteEve'']]

A mysterious, ancient evil that wants to reverse humanity's symbiotic relationship between the nucleus (banks of genetic information that dictate what cells grow where and when) and the mitochondria (organic power plants that fuel cellular activity). To this end, she takes over the body Kiyomi Nagashima, wife of mitochondrial expert Toshiaki Nagshima, and forces her to crash her car. Toshiaki cultures some of Kiyomi's liver cells, giving Eve a place to grow a body, and one of Kiyomi's kidneys is transplanted into fourteen year old girl Mariko Anzai, whom Eve mutates the womb of so it can give birth to the Ultimate Being. After obtaining some of Toshiaki's sperm and implanting it into Mariko, Eve dissolves, unable to keep up with the energy output needed to sustain her own body.

A second, unrelated Mitochondrial Eve (possibly, see ContinuitySnarl) takes over the body of New York opera singer Melissa Pearce in the ''VideoGame/ParasiteEve'' game with the same goal as her predecessor of creating the Ultimate Being. Eve-2 dissolves a solo performance crowd at Central Park into raw genetic material and allies with Melissa's former doctor, Hans Klamp, to procure sperm for her Ultimate Being. Aya Brea fights her several times around New York, but is unable to seriously stop her plans.

The original host of the second Eve is actually Maya Brea, sister of Aya Brea, who was in a fatal car crash and had her kidney donated to Melissa and her cornea to Aya.

* AntagonistTitle: Both Eves are the titular BigBad and PuppeteerParasite.
* ArchEnemy: Eve-2 is often seen as this to Aya.
* BarbieDollAnatomy: Several of Eve-2's later forms feature breasts that lack nipples, along with creative obfuscation of the pubic area. Strangely, artwork of Eve-2 in the official Parasite Eve artbook shows her having nipples, although the pubic area is still obscured.
* BigBad: Of the book and the first game.
* BishonenLine: Eve-2 hits this plateau in her evolution fairly quickly [[spoiler:and to an extent repeatedly]], and for a freakish mutation, she looks disturbingly fetish-worthy. Her final form is a lot more humanoid and angelic than her previous forms.
* BlobMonster: When Eve-1 grows she is described as giant piles of bloodless flesh.
* BodyHorror: Eve-1 is this, while Eve-2 mostly inflicts it on others while riding the BishonenLine. Some aspects of Eve-2's body are still very horrific, however, such as her first form's 'tail' and freakishly large hands.
* BreakThemByTalking: Eve loved to direct this towards Aya, hoping to force Aya to see things her way and join her or simply give up.
* ContinuitySnarl: The only way the second Eve could be directly connected to the Eve-1 is if the Mariko in the book [[spoiler:is the same Mariko that's Aya and Maya's mother]]. And that does not work because the events of the book take place in 1985 and [[spoiler:Aya and Maya's mother died in the 70s]].
* EvilLaugh: Her dialogue suggests this despite the fact that there isn't any voice acting in the first game. In the cutscene where she smashes the piano she was playing, however, she does let out a rather high-pitched laugh after mutating into her first form. It's rather chilling.
* FanDisservice: See BarbieDollAnatomy above. [[spoiler:Especially Eve-2's gestating form from the museum encounter in Day 5.]]
* FemmeFatalons: Eve-2's hands.
* GoOutWithASmile: A villainous example, [[spoiler:as after being defeated by Aya, she flashes a smile at her just before she dies, since she's already given birth to the Ultimate Being.]]
* GreenEyes: When Eve-2 takes over Melissa's body, her eyes turn from brown to green. They stay this color from then on out.
* HannibalLecture:
** Eve-1 gives one of these in a rhetorical question form at a lecture on mitochondria and a more direct one at a different lecture.
** Eve-2 loves giving these during her WeCanRuleTogether speeches to Aya, rambling about how the nucleus is long overdue for a subversion of its smug superiority over the mitochondria.
* [[HoistByHisOwnPetard Hoist By Her Own Petard]]:
** Eve-1: Never thought that [[spoiler:male mitchondria]] could actually be a threat.
** Eve-2: Never expected that the evolution she so fervently sought would produce her own superior on the food chain.
* HornedHairdo: Eve-2.
%%* HumanoidAbomination
* InstantDeathRadius: After a fashion. Eve-2 is capable of immolating/mutating/melting/what have you any organic creature close enough to her if she chooses. And "close enough" means a distance of at least several city blocks. Aya being immune to this is ability is why the police and later the army relies on her to hunt down Eve.
* LivingBodysuit: Kiyomi Nagashima, Mariko Anzai, and Melissa Pierce.
* MonsterIsAMommy: She wants to create an Ultimate Being by giving birth to it.
* MultiArmedAndDangerous: One of the forms she assumes when [[spoiler:Aya engages in the last battle with her on the collapsed Statue of Liberty]].
* PlayingWithFire: Her "aura" immolates people and animals (the ones that don't melt into goo or mutate).
* PowerFloats: Both Eve-1 and Eve-2 are capable of levitation.
* PregnantBadass: Eve-2's penultimate form is pregnant with the Ultimate Being. That time, she's the penultimate boss (of the regular game).
* PuppeteerParasite: Hence the "Parasite" Eve.
* RecurringBoss: She's fought many times throughout the game, in various forms.
* ShapeshifterModeLock: Eve-2 makes several changes throughout the first game and these changes appear to be permanent, as she is never shown reverting back to previous forms.
* SignificantGreenEyedRedhead: Eve-2's LivingBodysuit has GreenEyes and auburn hair.
* TookALevelInBadass: Eve-2 is way more powerful than Eve-1. She can set people on fire ''and'' mutate them, while Eve-1 was only able to set people ablaze.
* TwoFirstNames: Eve-2's LivingBodysuit, Melissa Pierce.
%%* TheVirus
* VoluntaryShapeshifting: Eve-1 is capable of this. Her favorite form is Kiyomi. Eve-2 sticks with a mutated Melissa, but does not show any sign of being able to shapeshift.

!!The Ultimate Being

Eve's "child", a human/mitochondria monster hybrid that has all of Eve's powers and complete control of its genetic code, that Eve wants to lead the mitochondria revolution. Eve succeeds in her goal of creating the Ultimate Being, but doesn't count on the male mitochondria from Toshiaki's sperm to rebel against Eve's mitochondria, causing the whole thing to self-destruct.

The second Eve also wants to create an Ultimate Being and spends most of the game attempting to create and give birth to one. In the normal game (Day 6), Eve dies but the being is born anyway, since she implanted it into the mito-mass at Liberty Island. Is the final boss of the regular scenario.

* BaldOfEvil: Especially so in the video game where each form he takes always has him bald.
* BiggerBad: Eve may be the main threat, but the Ultimate Being is the final one.
* EldritchAbomination: Dear god, there is barely anything human about it despite its appearance.
* EvolutionPowerUp: In the first game, the Ultimate Being undergoes various evolutions as the battle progresses. That was also the purpose of the Ultimate Being in the first place, being able to compress thousands of years of evolution into only a few minutes.
* FetusTerrible: The second Being's first form.
* FinalBoss: Is this in the first game.
* NoBiologicalSex: Played with in the first game. While it's safe to assume that it would be female, as the sperm used to conceive the being had no male mitochondria, the Ultimate Being's Adolescent form has a masculine-like appearance and has what appears to be testicles underneath its tail.
* RapidAging: During its fight with Aya, the Ultimate Being changed forms at various phases, its appearance making it seem like it was aging; starting with an infant-like appearance before turning into a child, adolescent, and finally, adult.
%%* SoapOperaRapidAgingSyndrome
%%* TouchOfDeath
* UltimateEvil: Starts off as an overgrown deformed baby and then evolves several times throughout the battle with each form becoming less humanoid and more freakish and unexplainable.
* UltimateLifeForm: Was a part of Eve's plan to have a child that could rival her power and conquer the world without it having any of the weaknesses that the previous Ultimate Being (novel) had.
* WeaksauceWeakness: The first Ultimate Being's weakness is [[spoiler:her/his dad's normal vanilla mitochondria. The second Ultimate Being that debuted in the game is weak to Aya's mitochondria via bullets laced with Aya's cells]].

[[folder:Debuted in ''Parasite Eve'' (the game)]]

!!Aya Brea
->'''Voiced by''': Creator/MaayaSakamoto (JP) and Creator/YvonneStrahovski (EN)

[[caption-width-right:140:[[labelnote:Her cutscene model in ''Parasite Eve'']]http://static.tvtropes.org/pmwiki/pub/images/aya-psvg.png[[/labelnote]]]]
[[caption-width-right:270:[[labelnote:Her artwork for ''Parasite Eve 2'']]http://static.tvtropes.org/pmwiki/pub/images/Aya_PE2_7765.jpg[[/labelnote]]]]
[[caption-width-right:260:[[labelnote:Her artwork for ''The 3rd Birthday'']]http://static.tvtropes.org/pmwiki/pub/images/likehappybirthdayandjunkaya_6189.png[[/labelnote]]]]

A 25-year-old police officer whose life changes when a date AtTheOperaTonight (tonight being Christmas Eve 1997) goes horribly wrong. As the only person to not not-so-spontaneously combust upon the awakening of Mitochondria Eve, she struggles to understand and rein in her own bizarre powers while racing to stop Eve from giving birth to the Ultimate Being and destroying and/or forcibly evolving humanity in the process. She's immune to Eve because they share donor organs from her twin, Maya. More on that further down.

Aya returns in ''Parasite Eve 2'', set three years after the events of ''Parastie Eve'' as an ace operative of the FBI's anti-mitochondrial mutant task force, MIST [[FunWithAcronyms (Mitochondrion Investigation and Suppression Team)]], formed following reports of Eve's mutated animal minions spreading out from Manhattan. Aya's journey to destroy the newly-monikered "Neo-Mitochondrion Creatures" ([=NMCs=]) and put a seal on her own unpredictable powers leads her to Los Angeles. However, an investigation into an NMC outbreak near the ghost town of Dryfield, Nevada hits closer to home.

Aya is the star in ''The 3rd Birthday'' but, apart from her name, she remembers nothing about herself or her past. When the CTI (Counter Twisted Investigation team) found her, she was wearing a bloody wedding gown outside the St. Thomas Cathedral in Manhattan, either just before or just after her own wedding. After taking her into custody, the CTI realized her abilities allowed her to dive into a human's past consciousness. Understanding that this was humanity's only chance against the space and time-defying Twisted, the Overdive Investigation Unit was formed to develop a way to use Aya's powers against them.

[[spoiler:Except this isn't Aya at all. It's Eve, from Parasite Eve 2, in Aya's body, the result of a failed EmergencyTransformation. As a result, she actually regains a mix of both her actual memories and Aya's, resulting in a ''huge'' TomatoSurprise.]]

* ActionGirl: Started off as a cop in the first game, becomes a specialized FBI agent in the 2nd game, and then becomes a CTI agent in the 3rd game.
* BareYourMidriff: Aya's outfit in ''3rd'' is a purple vest about one size too small.
%%* BigDamnHero: At the very end of ''3rd''.
* BizarreHumanBiology: Aya possesses [[spoiler:a more benign/passive form of the "evolved" strain of mitochondria serving as the the first game's BigBad, which are not only ''a self-aware HiveMind'' that can [[BodySnatcher hijack their "hosts"]] and act like TheVirus]], they possess actual ''superpowers'', which include [[PlayingWithFire spontaneous combustion]] and BodyHorror transformations!
* BloodSplatteredWeddingDress: When CTI found her.
* ButNotTooForeign: Half-Japanese, as a nod to the novel.
* CombatStilettos: Her high heels in the first game's beginning. She even goes into the New York sewers in them! Justified as she was on an opera date when Eve/Melissa first manifested and attacked the audience.
* CursedWithAwesome: Aya's mitochrondrial powers lack the villainous insanity and BodyHorror that other people in this series go through--[[spoiler:she received the "special" mitochondria when she was still a child, and unlike Melissa, Aya's mitochondria evolved to the point where they are symbiotic with her body and work with her instead of taking outright control]]. However, they also keep her body younger than she really is, since a youthful host is advantageous.
-->'''Aya''': (looking in a bathroom mirror) ''Here's looking at you, kid. I look like I'm in my early 20s... It's nice... but there's a reason. It's what my mitochondria want. I never asked for this. A youthful host is advantageous... [[ShoutOut I saw this movie]] [[Film/{{Highlander}} about a medieval knight who lived into this century]]. [[WhoWantsToLiveForever I don't want that]]. [[IJustWantToBeNormal I'll be happy to live just one, normal life]].''
* DeadAllAlong: [[spoiler:A trait she shares with a lot of characters in ''The 3rd Birthday''.]]
* DeadpanSnarker: More so in ''2'' than in ''1'' and ''3rd'', mostly when you have her examine something several times. "Do I have to look in there again?" is her comment if you keep trying to make her look into a dirty toilet.
* EnemyWithin: [[spoiler: After defeating the original Eve in the Chrysler Building in the first game, Aya feels her body getting hot and then hears a familiar voice in her head. It turns out that Eve was also inside Aya the entire time and has awoken thanks to Aya surpassing Maya/Eve. Eve aims to take over Aya's body, only to be killed off by what is apparently the good mitochondria possessed by Maya.]]
* {{Expy}}: Lessee here, beautiful with blonde hair and blue eyes, has a secret connection to the main villain who spends most of the game trolling her or trying to drive her crazy, paranoid and unsure of her past and what she is, a bit of a smartass, and has a unique genetic trait that gives her special powers. And the star of an RPG made by Squaresoft. Are we talking about Aya or [[VideoGame/FinalFantasyVII Cloud Strife?]].
* EyeRemember: Maya's cornea (which possessed Eve's mitochondrial power) was transplanted into Aya's right eye, and Aya's visions are actually Maya's last memories.
* ElementalPowers: Which she develops in''2''.
** [[PlayingWithFire Fire]]: [[FireBalls Pyrokinesis]], [[HandBlast Combustion]], [[StuffBlowingUp Inferno]]
** [[BlowYouAway Wind]]: [[PoisonousPerson Necrosis]], [[FullContactMagic Plasma]], [[ShockAndAwe Apobiosis]]
** [[HealThyself Water]]: Metabolism, [[HealingHands Healing]], LifeDrain
** [[StatusBuff Earth]]: Antibody, Energy Shot, [[DeflectorShields Energy Ball]]
* FairCop: Oh yes. She's caught the eyes of quite a few men. A short list includes her nameless date at the beginning of the series, Maeda, Pierce, and Kyle.
* FairytaleWeddingDress / PimpedOutDress: Her wedding dress in ''The 3rd Birthday''.
%%* TheGunslinger
* HyperspaceArsenal: Her gun is always a pistol in cutscenes, but may range up to and including a rocket launcher during gameplay with no encumbrance penalty.
* HypocriticalHumor: In the second game during her trip to Dryfield's grocery store, Aya will note how she refuses to touch junk food due to the large amounts of fat and calories, but she has no qualms with taking a can of soda, which is usually loaded with sugar. Soda must be related to her MP, considering the huge boost she gets from drinking it.
* TheHero: The main protagonist in the first two games.
* TheHeroDies: [[spoiler:She dies in ''3rd Birthday'' while on Eve's body. Eve lives on while on Aya's body, so that may be a subversion.]]
* IAmAMonster: Her main worry in the first game. After seeing how her powers are similar to Eve's Aya freaks out and tells Daniel and Maeda to go away so that she doesn't hurt them if she does become a monster like Eve. Luckily, Daniel and Maeda stick by her and she quickly gets over it.
* IJustWantToBeNormal: Her stock flavor of angst for the first couple of chapters, peaking in an {{I Am A Monster}}-flavored HeroicBSOD.
* IconicOutfit: Her sexy black dress from the first game's beginning is very well associated with her, despite that she only wears it for at most, an hour's worth of gameplay.
* ImprobableAimingSkills: Zigzagged in the first game: her shots would miss if the target was too far away from her, but if she was close enough, she could always hit her targets even if they were moving in fast and erratic patterns. Played straight in the second game, she's a great shot, such that she can pick the wings off of mutant moths at range. Some flavor text in the MIST HQ also reveals she got 2nd place in the most recent MIST shooting competition, losing out only to Rupert Broderick.
* ItWasWithYouAllAlong: Discovered at the end of ''1''.
-->[[spoiler:'''Aya''': Maya. I was always waiting...waiting for you to come home with mom. And I've always been looking for the other "me". But you were always right there with me Maya...''always'', all this time.]]
* KickingAssInAllHerFinery: Spends the first act of the very first game clad in her {{iconic|Outfit}} LittleBlackDress.
* KilledOffForReal: [[spoiler:Along with Eve's body to prevent the creation of the Twisted at the end of ''3rd''.]]
* LittleBlackDress: The out she wears during day 1 when she went to the opera.
* LooseLips: During an interview with the press over the Carnegie Hall burnings, Aya winds up telling the press exactly what happened with Eve and the monsters, despite Baker telling her to keep quiet about it. Naturally, this causes confusion and panic within the media and Aya gets reprimanded by Baker for giving out sensitive information.
* MagicKnight: Skilled with any firearm, and has a collection of powerful magic (Parasite Energy) to back her up.
* MissingMom: Her mother died in a car crash along with Maya. Aya was raised by her father.
* NoSell / OnlyICanKillHer / TheImmune: Her immunity to Eve's powers makes her [[ItsUpToYou the only one]] that can fight her effectively.
* OldCopYoungCop: The Young Cop to Daniel's Old Cop. She's in her mid-twenties while Daniel is a contemporary and former partner of DaChief.
* OldHeroNewPals: Every game she has a new set of supporting cast and antagonists. The closest she has for consistent on-screen allies are Kyle and Eve, both of whom only debuted in the second game.
* OlderThanTheyLook: Was 25 during the first game, 27 in the second game, 38 in 3rd, looks barely 21, leading to WhoWantsToLiveForever. This is explained in that, since her evolved mitochondria have opted to work with her rather than against her (which is the defining difference between Aya and the various monsters around her), they've decided that keeping their host healthy and young is more advantageous to them than allowing her to age.
* OutOfClothesExperience: When she goes into Liberation mode.
* PopCulturedBadass: ''Film/{{Casablanca}}'' and ''Film/IndianaJonesAndTheLastCrusade'' in the same sentence, while observing herself in a mirror and contemplating turning into a hundreds of years old knight. While mourning that her car was destroyed by monsters she brings up naming it Literature/{{Christine}} and, naturally, makes numerous references to ''Franchise/FinalFantasy.''
* SaltAndPepper: Aya and Daniel. With Rupert in the second game.
* ShesGotLegs: Her dress in the first game has a nice long slit up its side. Then in the second game her outfit when arriving at Dryfield has a pair of knee-high boots and some pretty short shorts that show off her fantastic legs.
* SmallGirlBigGun: She can equip large rifles and finds a [[{{BFG}} rocket launcher]] about 3/4 into the game. In the sequel one of her unlockable weapons is a portable railgun that sends her back a few feet whenever she fires it!
* SurvivorGuilt: A possible interpriation as Aya doesn't like the idea of anyone sacrificing themselves for her. Probably from having survived a car crash that killed her mom and sister, being the only survivor of the massacre at Carnegie Hall, and had various pilots sacrifice themselves so she can kill Eve.
* ThemeTwinNaming: She's one letter short of having the same name as her late twin sister Maya.
* WhoWantsToLiveForever: Mentioned if you check the bathroom mirror in her motel room in Dryfield. [[ChristmasCake This is also how you know why she doesn't look like an old crone at the ripe old age of 27.]]
* WhoWearsShortShorts: In ''2''.

!!Daniel "Bo" Dollis

Aya's partner and BlackBestFriend; combined, the manual refers to them as the "Father and Daughter Team" of the NYPD's 17th Precinct. His introduction is a DynamicEntry that sets the tone for his take-no-nonsense approach to the Eve case, along with his determination to thwart any mundane threat that sets its eyes on Aya or his son Ben.

* ActionDad: A veteran cop with one son.
* AlliterativeName: '''D'''aniel '''D'''ollis.
* AmicablyDivorced: Despite appearances, Daniel and Lorraine remain close. He takes her death as hard as any loving spouse would. It turns out that Lorraine was considering patching their family back together.
* AngryBlackMan: Becomes very pissed off at the antagonists for not only putting Ben's life in danger, but for also killing his ex-wife whom he planned to reconcile with so they could become a family again.
* BadassInANiceSuit: Is wearing a yellow suit and is one of the resident badass in the first game.
* BadassNormal: Despite not having special abilities like Aya, it doesn't stop him from helping her out when it's called for and he kicks absolute ass when he does.
%%* BadassMustache
* BigDamnHero: Pulls off a spectacular one when Aya is at her wits end on how to kill the Ultimate Being. Daniel takes the special bullets Maeda made for Aya, leaps out of the helicopter, catches on fire mid fall, and hurls the magazine towards Aya (who somehow manages to catch it!) before he plummets into the ocean ''and survives''.
* DynamicEntry: The first of his several [[Awesome/ParasiteEve Crowning Moments of Awesome]].
* HotBlooded: He is easily riled up.
* LethalChef: According to Aya in the sequel, he is a terrible cook.
* MadeOfIron: He shrugs off being nearly combusted by the EldritchAbomination of a FinalBoss just so he could deliver Maeda's special bullets.
* MarriedToTheJob: The reason why Lorraine left him in the first place.
* OldCopYoungCop: The Old Cop to Aya's Young Cop. He's a contemporary and former partner of DaChief while Aya is in her mid-twenties.
* OlderSidekick: He's older than Aya.
* PapaWolf: You don't mess with his son, even if you're are an evil sentient form of mitochondria.
%%* SharpDressedMan
* SinkOrSwimFatherhood: Lorraine divorced him a year before the game starts, leaving him sole custody of their son Ben.
* UnexplainedRecovery: He was already combusting when he delivers Maeda's special bullets to Aya before falling to the water. The scene following the FinalBoss' death shows him just fine.
* YouAreInCommandNow: Becomes acting [[DaChief chief]] of the precinct from Day 4 onwards due to Baker's injury.

!!Benjamin Dollis

Daniel's son, in the custody of his ex-wife Lorraine due to his long hours on the force. Initially planned to reunite the family at Melissa Pearce's Central Park solo concert, but Eve's awakening changed all that. Along with Lorraine, he was meant part of the mito-mass that became the Ultimate Being's uterus, although he survives. Likes dogs, and is quickly introduced to the K-9 unit's Sheeva, which goes about as well as you'd expect for a game reveling in its high levels of TransformationTrauma.

* BreakTheCutie: The poor kid's heart is broken when he sees Sheeva transform into a monster and begs Aya to kill it.
* MissingMom: Lorraine was killed off in Day 2.
* NonActionGuy: He's not combat proficient. Justified due to his age.
* SecondEpisodeIntroduction: Introduced during Day 2 of the first game.
* TagAlongKid: He was visiting his father at the police station when shit went down.

!!Kenneth Baker

Chief of the NYPD 17th. Joined the force at about the same time as Daniel, and still maintains casual terms with him despite their difference in rank. Takes care of Ben while Daniel and Aya are on the scene in Central Park, only to get himself injured protecting him from the mutated Sheeva.

* BadassInANiceSuit: Is wearing a suit and is the resident BadassInCharge.
%%* CommanderContrarian
* DaChief: Despite not having any {{Cowboy Cop}}s to his name, he's still pretty gruff - evident when Aya lets a little too much slip during a press conference on the Carnegie Hall fire investigation.
* DeathByAdaptation: In the manga adaption, ''Parasite Eve: Diva'', he dies during the attack on the police station.
* DeskJockey: Became one when he was promoted to chief.
* LargeAndInCharge: Very tall and stock, which suits him as the police chief.
* ReasonableAuthorityFigure: He believes Aya's report about the events at the opera house and authorizes her to take an assault rifle from the police armory.
* SecondEpisodeIntroduction: Introduced during Day 2 of the first game.
%%* SharpDressedMan
* ShootTheDog: Is stuck doing this.
* WeUsedToBeFriends: His imperious ways rub Daniel raw. They used to be partners before Kenneth was promoted.

!!Kunihiko Maeda
->'''Voiced by''': Hiroaki Hirata (JP) and Joe J. Thomas (EN)

Japanese biologist and walking {{Infodump}} for the events of the novel, who hopped the first plane to New York when he heard of the fire at Carnegie Hall. After rescuing Aya following her clash with Eve at Central Park, he relates the tale of the original Eve's attempt to birth an Ultimate Being and discovers the reason behind Aya's immunity to the current Eve. Afterwards, his main role is dispenser of inventory space-wasting good luck charms, including one literal ChekhovsGun.

Maeda returns in ''The 3rd Birthday'', once again assisting Aya with his research into the Twisted.

* CannotSpitItOut: [[spoiler:To Aya during the ending]].
* ChekhovsGun: Gives you a weak handgun late in the game. Combined with the bullets mentioned below, it becomes a lethal weapon against the final boss. Appears in the sequel as the [[InfinityMinusOneSword Mongoose]].
* DepletedPhlebotinumShells: [[spoiler:The Maeda Bullets]].
%%* GeniusDitz
* {{Infodump}}: For the Hideaki Sena novel.
* NonActionGuy: Since he's a scientist and serve's as the group's exposition, he has no combat experience and wisely stays out of trouble while the others do the leg work.
* SecondEpisodeIntroduction: Introduced during Day 2 of the first game.

!!Torres Owens and Wayne Garcia

Quartermaster of the 17th's armory and his assistant/apprentice, respectively. Torres is hell-bent on making sure guns are used responsibly, having sworn off using them since his daughter died in a mishap with a loaded one. This tends to make him clash loudly with apprentice Wayne, an adherent to the MoreDakka school of gun control. Both provide Aya with the facilities to modify weapons and armor to increase their bonus slots, and space to store unneeded items.

Wayne, not being allowed to handle the guns without supervision, takes to collecting gun trading cards instead. Feed his hobby following Torres's death during the raid on the precinct and you'll eventually be rewarded with the [[InfinityPlusOneSword Infinity Plus and/or]] [[InfinityMinusOneSword Minus One Toolkits]].

* CharacterDeath: Torres was killed by a {{Bonus|Boss}} MiniBoss in Day 3.
* CynicalMentor: Torres has little faith on Wayne, though he wished him the best on his final YouAreInCommandNow speech.
* DiedInYourArmsTonight: Torres dies on Wayne's arms.
* DoesNotLikeGuns: Torres used to be a good shot, but asked to be transferred to storage work after his daughter was fatally shot by accident. He states that he asked to so he could keep guns under control.
* GadgeteerGenius: Wayne is the guy you'd go to if you want to customize your weapons and armors.
* ItsAllMyFault: Torres blamed himself for his daughter's death in a freak accident with one of his guns, thus he refuses to fire a gun and prefers to maintain them instead so they'll be safe for use. When the precinct is attacked on day 3, he doesn't shoot the monster (or hadn't used a gun in so long that he didn't know how to fire it properly) attacking him and dies as a result.
* OldCopYoungCop: Torres is more experienced while Wayne is implied to be closer to Aya's age.
* OutlivingOnesOffspring: Torres' daughter was a victim of AccidentalMurder via accidental shooting. This is the very reason why he DoesNotLikeGuns.
* SecondEpisodeIntroduction: Both are introduced during Day 2 of the first game.
* ShoutOut: They return (sort of) as proprietors of the Lindblum Synthesis Shop in ''VideoGame/FinalFantasyIX'', and reprise their argument when you first walk in: Wayne believes the key to victory is superior weaponry, where Torres puts his faith in superior armor.
* StraightManAndWiseGuy: Played rather seriously.
* YouAreInCommandNow: After Torres dies, Wayne becomes the head of weapons storage.

!!Warner, Nix, and Cathy

They're also on the force.

* GuideDangIt: Cathy provides one if the player has no clue on what to do.
* SecondEpisodeIntroduction: They were all introduced during Day 2 of the first game.
* ThoseTwoGuys: Or those three guys. They serve as nothing more than background characters and they need to be saved during Eve's attack on the police precinct.
* WhatHappenedToTheMouse: Nix disappears after Day 3, Cathy after Day 4, and Warner after Day 5.

!!Hans Klamp

Anthropologist at the Museum of Natural History, who is mysteriously at work despite both the Christmas holiday and an evacuation of Manhattan following Eve's audience liquification event at Central Park. Oversaw the operations that transplanted Maya Brea's organs into Aya and Melissa, supplied Melissa with enough immunosuppressants to let the mitochondria in Maya's kidney take her over as Eve, and removed the mitochondria from his sperm to make it prime material for fertilizing the Ultimate Being. Apparently has been pulling a LongCon and considered a variety of potential organ recipients for creating the UB, as Lorraine Dollis is listed on the same HLA list that he pilfered from St. Francis Hospital.

* BeardOfEvil: Certainly fits the mold once you know his true motives.
* BetterToDieThanBeKilled: Calls on Eve to "take him" when Aya arrives to place him under arrest. He combusts.
* DontYouDarePityMe: Aya rushes to his aid after Eve sets him aflame. Characteristically, the Doc sneers at her human weakness.
* EvilGenius: Par for the course when one is a scientist.
* {{Expy}}: Klamp bears striking similarities to Professor Hojo from ''VideoGame/FinalFantasyVII'', which include creating monsters and assisting the BigBad [[ForScience in the name of science]].
* HereComesTheScience: Where Maeda was the {{Infodump}} for the novel, Klamp takes his {{Exposition Break}}s expounding on an understanding of genetics [[HollywoodScience as]] [[Franchise/MetalGear shoddy]] as Creator/HideoKojima's.
* {{Jerkass}}: Dr. Hans Klamp is a total snob to Aya and Daniel in the beginning of the game and dodges their questions while acting all high and mighty. Even when Daniel later on finds his ex-wife and son's name on Klamp's computer and threatens to kick his ass, Klamp coldly tells him and Aya to leave.
** He has his reasons for blowing them off: [[spoiler:he's actually helping Eve give birth to the Ultimate Being, which becomes the final boss of the game]]. Which really makes him a jerk, to put it lightly.
* KarmicDeath: [[spoiler:Up and asks for one, having completed his part of the plan]].
* MadScientist: Even before you know who he truly is, his normal self still has shades of this.
* MisanthropeSupreme: Sells out humanity for [[spoiler:the narcissistic desire to have ''his'' male sperm used to create the Ultimate Being]].
* ANaziByAnyOtherName: Wants humans and other beings eradicated so that only the strong forms of mitochondria come out on top.
* NonActionGuy: Does a lot of scheming behind the scenes, but doesn't do anything directly (that's Eve's job).
* WhiteShirtOfDeath: [[spoiler:He combusted while wearing his labcoat.]]
* XanatosGambit: Has two plans set in motion, though the main story only shows one while the other can only be seen through NewGamePlus. [[spoiler:To help Eve achieve her goal, he implants some sperm into her so that she can become pregnant and give birth to the Ultimate Being without her or the child succumbing to any side effects like the original Eve and Ultimate Being had gone through during the novel. By doing this, Eve can take over the world. Should Eve and the Ultimate Being be defeated, Klamp can rely on a ''second'' Eve from Maya's body that would finish what the main Eve had started and this particular Eve is more powerful than the one from Melissia since Maya's mitochondria is stronger due to it being the purebred.]]

!!Maya Brea

Is dead. Aya keeps having visions and flashbacks of her as she pursues Eve, though. Is also [[spoiler:the BonusBoss]].

Aya's visions are due to having received a transplant from Maya. Aya had a defect in her right eye since birth, and received Maya's cornea as a transplant. Which is how Aya will later in life [[spoiler:acquire her mitochondrial powers]].

* AlwaysIdenticalTwins: The character models for Maya and young Aya are dangerously similar, if not recycled outright.
* DeathByOriginStory: She died before the start of the story.
* PlotTriggeringDeath: Her cornea being transplanted into Aya is the reason she's [[spoiler:[[TheImmune unaffected]] by [[BigBadMitochondria Eve]]'s powers of spontaneous combustion and forced Neo-Mitochondrial mutation]], otherwise she would've never lived to fight against [[spoiler:Mitochondria Eve]] in the first place. Her kidney being transplanted into [[spoiler:Melissa Pierce]] leads to her becoming [[spoiler:the unwilling host of [[BigBad Mitochondria Eve]]]]. The very plot of the game hinges on her dying and becoming an organ donor for those two characters.
* ThemeTwinNaming: Remove the first letter of her name and she and her twin sister are both gonna be named Aya.
* TragicMonster: Her body possessed [[spoiler:the most evolutionary form of mitochondria]], which led her to be [[spoiler:host of the Original Eve]].
* TrueFinalBoss: The final boss of the [[NewGamePlus EX Game mode]], [[spoiler:Purebred Eve]], is [[spoiler:Maya's body possessed by Eve's mitochondria]].
%%* VirtualGhost

[[folder:Debuted in ''Parasite Eve II'']]

!!Rupert Broderick

The new Daniel. Still [[BlackBestFriend black]], still [[BadassNormal badass]], and about the same aptitude at dealing with [=NMCs=] and twisted humans alike.

* BadassInANiceSuit: Rupert is always well dressed...be it at the office or in the field.
* BadassNormal: He's pretty much a OneSceneWonder. He saves Aya from an ambush early in the game and unloads a ton of lead into the first Stranger, but sadly, he's wounded and out of commission for the rest of the game.
* BaldOfAwesome: Only emphasizes how bad ass he is on duty.
* BlackBestFriend: Unfortunately, despite his EstablishingCharacterMoment being a badass with a huge HandCannon, he's out of the picture for most of the game. He's probably the HeroOfAnotherStory.
* DaChief: [[spoiler:In the True Ending, he takes over the MIST Office after Baldwin is arrested for his treachery.]]
* ImprobableAimingSkills: Examining some items in the shooting range at MIST reveals he got 1st place in the most recent shooting competition there.
* ItsPersonal: He lost his family during the N.Y. Blockade incident. Now he dedicates his life to exterminating neo-mitochondrion creatures.
* RevolversAreJustBetter: He wields the Mongoose at the start of the game, which he gives to you only if you're on the Sad Ending route.
* WaistCoatOfStyle: Part of his BadassInANiceSuit attire, he's almost always seen wearing this, and never a jacket.

!!Pierce Carradine

Somewhere between "The new Wayne" and "The new Maeda" falls MIST's resident computer whiz. Though he just plain DoesntLikeGuns, that's about the only hindrance to his assistance to Aya via HollywoodHacking or item delivery.

* {{Adorkable}}: Somewhat shy and awkward, and always unflinchingly friendly and helpful.
* DoesNotLikeGuns: Lampshaded by Jodie. He's also quite bad with them, as he once tried to load 9mm Parabellum rounds into a .38 revolver (in his defense, those have only a half millimeter difference in diameter). Ironically, he oversees the shooting range at HQ.
* HopelessSuitor: Pretty obvious he has a big crush on Aya, but she doesn't reciprocate.
* KilledOffForReal: Depending on the ending route.
* NonActionGuy: Pierce gets himself into trouble while trying to help Aya out. Whether he survives or not [[MultipleEndings depends on the player's actions.]] And [[GuideDangIt whether you have a damn clue how to take those actions.]]
* PlayfulHacker: Was known to do this during his spare time before he was caught by the government. Now he puts his hacking skills to use for them.
* SunglassesAtNight: Is never seen without them.

!!Eric "Hal" Baldwin

Aya's new boss. Far too impersonal to call "The new Baker". More like "The new Klamp". The MIST team like to call him Hal because his cold demeanor is reminiscent of [[Film/TwoThousandOneASpaceOdyssey the HAL-9001 supercomputer.]]

* DaChief Lite
* KarmaHoudini: If you don't get the True Ending, he apparently skips town and avoids any punishment for his actions. To get the True Ending, though, Aya calls Jodie and tells her about her suspicions, and Rupert confronts him, which leads to his arrest.
* TreacherousAdvisor: Is in on [[spoiler:the Neo-Ark Project,]] and may have helped [[spoiler:procure Aya's cellular samples to assist them in cloning this newest breed of [=NMCs=].]]

!!Jodie Bouquet

Runs MIST's BP shop ([[GlobalCurrency Bounty Points]], not British Petroleum). She'll only appear near the end of the game if you're on the good ending path and it's also possible to never meet her depending on your actions.

* ArmsDealer: She's your armory/item shop at the start.
%%* HairDecorations
%%* GenkiGirl

!!Gary Douglas

The last living resident of Dryfield (excepting his dog, Flint, and the hordes of [=NMCs=] Aya's come to clean out). A Vietnam vet with a gun collection big enough to claim the title of "The new Wayne", he helps Aya resupply during the investigation despite being compensated in [[GlobalCurrency some newfangled RPG currency]] rather than cold hard cash. After Aya's car is totaled by a herd of [=NMCs=], he also volunteers his truck to get her and Kyle to an old nuclear shelter that may be the source of the infestation.

* ArmsDealer: During the latter half of the game.
* BigFriendlyDog: His dog Flint.
* CoolOldGuy: Despite his gruff demeanor, he means well and assists Aya to the best of his abilities.
* CrazyPrepared: Was apparently ready for the ANMC menace, having singlehandedly booby-trapped the entire town with everything from bear traps to landmines.
* CrazySurvivalist: Subverted; he has all the hallmarks of being one, in that he's the sole living person in a town that suffered a pseudo-ZombieApocalypse, and he's loaded to the gills with weapons and supplies, but he's hardly crazy, and is quite a friendly guy.
* HandicappedBadass: He lost a leg in a minefield during Vietnam.
* JerkWithAHeartOfGold: He's very weary around Aya do to his initial distrust with FBI agents, but he eventually warms up to her.
* NiceHat: Wears a ten gallon hat.
* RetiredBadass: He's a decorated Vietnam vet who lost a leg in a minefield.
* ShotgunsAreJustBetter: His WeaponOfChoice.
* WallOfWeapons: the caretaker thereof.

!!Kyle Madigan
->'''Voiced by''': Creator/KoichiYamadera (JP) and Creator/JensenAckles (EN)

A so-called private detective Aya encounters in Dryfield, claiming to be looking into strange shipments going into a nearby nuclear shelter once owned by a doomsday cult. Since he's one of the few EscortMission escortees in the business who doesn't suck for some reason or another, Aya teams up with him to discover the shelter's connection to the new [=NMCs=]. Is a DoubleAgent for what's left of the Neo-Ark group, hired to bring Aya so that she could open the pathway to a runaway test subject. In turn, he was planted in Neo-Ark by the U.S. government, to pinpoint their Ultimate Being analogue for destruction via [[KillSat orbital railgun]].

Kyle returns in ''The 3rd Birthday''. Aya keeps seeing visions of him while she battles the Twisted, but initially does not remember who he is.

* DoubleAgent: Kyle Madigan is actually a government agent sent to infiltrate the Ark organization, which in turn sends him to gain Aya's trust and manipulate her.
* DoubleReverseQuadrupleAgent: He's working with Aya, the Project and the government.
* IconicSequelCharacter: Despite being Aya's most notable LoveInterest, he only debuted in the second game.
* TheMole: He's a government agent infiltrating the Neo-Ark Project.
* OfficialCouple: With Aya.
* ATasteOfPower: When teaming up with Aya for combat sequences, usually wields a cool weapon from the next shopping tier or two up.
* SecondEpisodeIntroduction: Introduced during Day 2 of the second game.
* ShootTheDog: Was going to kill [[spoiler:Eve but Aya stops him, as she saw that Eve was just a scared little girl who didn't want to be used as a power/control source anymore]].
* ShootYourMate: [[spoiler:Near the end of the second game, No. 9 orders him to kill Aya. He fires, but he adjusts his aim to only hit her arm. This apparently satisfies 9, as he turns back to Eve to laugh... which gives Kyle the chance to shoot him in the head.]]
* WeCannotGoOnWithoutYou: Game Over for Aya if Kyle loses all 100 of his non-healable HitPoints. (Thankfully, he's not as screwed as he looks during the first major battle of Disc 2.)

!!Number 9

As the main series page calls him, "[[NinjaPirateZombieRobot a Gunblade-slinging rooftop-hopping ape-like zombie cyborg supersoldier]]" who masterminds an NMC outbreak at the Akropolis shopping center and is apparently the last sentient resident of the Neo-Ark shelter - his colleagues having either become [=NMCs=] themselves in some [[NoTranshumanismAllowed half-assed transhuman orgy]] or been killed by said voluntary converts. Hired Kyle, whether of his own will or at Baldwin's request, to escort Aya to Neo-Ark so she would eventually disable various barriers that his "queen" had erected around herself.

* {{BFS}}: Though his use of a [[VideoGame/FinalFantasyVIII Gunblade]] is more memorable, he DID pack a mean randomly-on-fire machete during his first showdown with Aya.
* DragonInChief: Number Nine is the closest we have to a main antagonist, but he's not actually in charge of the big plan, just following it out. Whoever orchestrated it is long gone, either killed or turned into an ANMC.
* EliteMook: Not all that evident, with anything resembling a BigBad proper already dead.
* FlamingSword: During the first boss fight with him in LA.
* LaughingMad: He's really easily amused.
* NeverFoundTheBody: [[spoiler:After fighting him in Dryfield, Aya's mitochondrial power goes out of control and she sets him on fire before she passes out. Hours later, when Kyle shows up at the scene, there's no sign of 9. Of course he's not dead and he returns for the finale.]]
* NinjaPirateZombieRobot: Two and a half out of four ain't bad.
* OneHitKO: During the first fight with him, his flame sword attack is a guaranteed kill, moreso if he's backed Aya in a corner.
* RecurringBoss: He is fought at both the Akropolis Tower and later in Dryfield.
* VaderBreath: Even when he loses his mask in the endgame, he's still breathing like this.
* YouAreNumberSix: Though practically revelling in the inhumanity that this trope entails.

->'''Voiced by''': Rei Okamoto (JP) and Creator/MollyQuinn (EN)

Not the same the NietzscheWannabe of the last game, however - this new Eve is a MysteriousWaif cloned from Aya herself and [[TheWoobie raised in isolation with the shittiest children's toys known to man]] - all to heighten her sense of fear and self-preservation as the eventual living engine for Neo-Ark's not-quite-an-Ultimate-Being. At least her teddy bear's halfway normal. She gets absorbed into the final boss, but Aya manages to save her. With Rupert's help, Aya adopts the girl as a sister. Eve also apparently lost most of her power, but overall she's quite well-adjusted and is going to school in the end.

Eve returns in the ''The 3rd Birthday'' with an expanded role. Eve disappeared after the incident at Aya's wedding at St. Thomas Cathedral. All information on her is from Aya's personal testimony, as she doesn't appear in any records in government databases. After a particular disturbing flashback concerning her, Aya decides to use her Overdive ability to look in the past for the cause of Eve's disappearance, and hopefully learn how to save her.

She is the true PlayerCharacter of ''The 3rd Birthday''. When the SWAT team attacked St. Thomas Cathedral, Aya and all of the other attendees to the wedding were gunned down. In a desperate attempt to save her, Eve dived into Aya's dying body, and quickly killed the soldiers. However, in the process, she destroyed Aya's lingering soul. Eve, in the shock and confusion from what she had just unconsciously done (and the identity crisis of having bits of Aya's soul mix with her own), failed to return to her own body and fainted. When she awoke, she had completely lost her memories, and found herself in the care of Hyde Bohr, the head researcher for the CTI. Unknown to her, in the intense stress during the incident where she lost her memories, her already advanced cells made a huge evolutionary step, and her abandoned body decayed to create the sentient High Ones -- the natural predators to the Twisted.

* ActionSurvivor: She was a young teenager in a woman's body who had to learn fighting from scratch -- you've gotta give her credit for her tenacity.
* BrainwashedAndCrazy: She was raised to be this way, amplified by being forced to wear a [[VideoGame/FinalFantasyVI slave crown]]-esque helmet.
%%* BodySurf
* BodySnatcher: Unintentionally.
* ChangingOfTheGuard: She's now essentially [[spoiler:TheHero of the video game series as of ''3rd Birthday'']]
* CloningBlues: She's a clone of Aya.
* ClonesArePeopleToo: Which leads Aya to [[spoiler:save the girl and adopt her.]]
* ClothingDamage: Like you wouldn't believe in ''3rd''. While it can be quite interesting, [[RealityEnsues the more skin Eve shows the more damage she takes]].
* CuteMute: She never speaks until late in the second game.
* DamselInDistress: She gets kidnapped by No. 9 late in the second game, and the finale consists of Aya chasing after her.
* DeadAllAlong: Well, her ''body'' anyway, in ''3rd''.
* GirlsLoveStuffedAnimals: Her prized possession is a teddy bear.
* HappilyAdopted: Becomes Aya's little sister in the good ending and enjoys her life as a normal child.
* HealingFactor: Like her "sister" Aya.
* IconicSequelCharacter: Debuted in the second game and becomes [[spoiler:the main character of ''3rd Birthday'']]
* LegacyCharacter: [[spoiler:To the BigBad of the same name in the first game, created by a secret organization to control the [=NMCs=] and [=AMNCs=] just like how the Eve before her did things.]]
%%* MysteriousWaif
* LimitBreak: Liberation mode, her main power in ''3rd'', in which Eve's powers break free of their limitations, letting her [[GunsAkimbo dual-wield]], dance circles around enemies and fire very powerful energy blasts. Can come with a DangerousForbiddenTechnique (Inferno, which is CastFromHitPoints) if the player is inclined.
* MikeNelsonDestroyerOfWorlds: She created the Twisted by sheer accident.
* MsFanservice: Has {{Stripperific}} clothing as options to wear in ''3rd'', whenever she takes too much damage her clothes get damaged to show off her body, and has a shower scene with MaleGaze galore.
* PoweredByAForsakenChild: She was created to be used as [[spoiler:a living power source for Neo Ark's Ultimate ANMC]].
* PromotedToPlayable: Technically in ''3rd Birthday'' because [[spoiler:she's on Aya's body]].
* TheQuietOne: In her debut game, she's too afraid to speak at first, but she eventually talks with just one line.
* RedeemingReplacement: She's a good person unlike previous characters who share her name.
* SecondEpisodeIntroduction: Introduced during the second game.
* ShoutOut: One of her alternate costumes in ''3rd'' is Lightning from ''VideoGame/FinalFantasyXIII''.
* {{Stripperific}}: In ''3rd'' although she always wears her default outfit in cutscenes, some of the other outfits that she can wear are quite revealing, and that's before taking damage. The developers {{Lampshade}} this with her maid costume-they point out she's wearing it "for fun".
* TomatoInTheMirror: She isn't [[MindScrew who she thinks Aya thinks she is.]] Revealed at the end of ''The 3rd Birthday''.
* WeCannotGoOnWithoutYou: [[spoiler:There's one sequence where Aya must escort her out of a room that is slowly being filled with poison gas. Eve cannot defend herself at all, and if her HP hits 0, the game is over.]]
* WoobieDestroyerOfWorlds Her "play room" was deliberately designed to frustrate her, and those loudspeakers in the walls that keep Aya from using her powers? They were meant for Eve. [[spoiler:If she hadn't tried to save Aya, the Twisted wouldn't have been created and Eve's own body wouldn't have decayed and evolved into the High Ones.]]
* YoungerThanTheyLook: She has the appearance of a 10 year old girl, but was presumably "grown" in a much shorter amount of time.

[[folder:Debuted in ''The 3rd Birthday'']]

!!Hyde Bohr
->'''Voiced by''': Takashi Taniguchi (JP) and James M. Connor (EN)

Chief researcher for the CTI and head of the Overdive Investigation Unit. A friendly mentor to Eve and the other people in his unit, he is devoted to finding a way to stop the Twisted. Like EVERY character in this game, he's not quite what he seems, though. Hyde is actually one of the most powerful High Ones -- a race evolved from Eve's remains that is dedicated to the eradication of the Twisted at all costs. He gathered and sub-consciously controls the other High Ones in the group.

* AdamAndEvePlot: Sort of... he wants to combine with Eve, whom he considers to be the Mother of the High Ones race and create an ultimate race.
* BodySnatcher: As a High One, he stole the original Hyde's body in the first place. Also gained the ability to Overdive when Eve dived into him near the end of the game.
* TheChessmaster: In his quest to go back to Time Zero.
* DeadAllAlong: Killed at "Time Zero", at St. Thomas Cathedral, where he was attending Aya's wedding.
* GunsAkimbo: It's hard to notice in the midst of battle, but Hyde dual wields ''two M4s'' with ease.
* HumanoidAbomination: Is a [[EldritchAbomination High One]] in disguise.
%%* ManInWhite
* ManipulativeBastard: [[spoiler:Hyde Bohr's using Eve to kill High Ones to allow him to go back to time zero.]]
* PuppeteerParasite: Hyde as we know him, and Eve's other CTI teammates controlled by him.
* TeamDad
* WellIntentionedExtremist: [[spoiler:Hyde takes advantage of the Twisted incidents to travel back to Time Zero, where he would merge with Eve and become the pioneer of a higher lifeform. Nevermind the people who died in said incident.]]
** [[spoiler:A bit of FridgeBrilliance, the Twisted turn out to be this. Being the fragmented pieces of Aya's "soul" that were sent to the future due to Eve's Overdive, they abduct and kill people to make the Babels grow and merge into the Grand Babel, which would enable said pieces to travel back to Time Zero and undo those events by taking control of Aya for a little while.]]

->'''Voiced by''': Ryohei Kimura (JP) and Patrick Cavanaugh (EN)

The chief engineer of the CTI's Overdive Unit, originally hailing from South Korea. He joined the CTI at Hyde Bohr's request.

* HeelFaceTurn: At the age of 14, he was notorious for unleashing a Trojan horse that stole sensitive information. After being arrested, he ended up with a plea bargain, and began to work for the government in order to take down the communication networks of terrorists. That earned the ire of his fellow hackers, so he survived by wiping out his personal history and starting over from scratch.
* HollywoodHacking: His specialty.
* KilledOffForReal: By Kyle Madigan.
* OnlyKnownByTheirNickname: We never know his real name. He purposely intended it to start over from a blank slate after a life of being a malicious hacker.

!!Thelonious Cray
->'''Voiced by''': Creator/HisaoEgawa (JP) and Chris Jai Alex (EN)

Formerly a Special Ops combat specialist, he left his squad to join the CTI team. Soon after, his whole squad was annihilated in the ill-fated Operation Red Fog. Was outside of St. Thomas Cathedral at the time of SWAT raid. He's another High One, created when Eve's body deteriorated at Time Zero.

* DeadAllAlong: Killed at "Time Zero", at St. Thomas Cathedral.

!!Gabrielle Monsigny
->'''Voiced by''': Creator/YukoKaida (JP) and Melinda Hill (EN)

A special agent in the CTI's Overdive Investigation Unit. Her friendship with Eve is a sisterly bond. She's also a High One, created when Eve's body deteriorated at Time Zero.

%%* CoolBigSis
* DeadAllAlong: Killed at "Time Zero", at St. Thomas Cathedral.
%%* FriendlySniper
* RivalTurnedEvil: Subverted. [[spoiler:Gabrielle didn't '''want''' to attack Eve.]]

!!Hunter "Boss" Owen
->'''Voiced by''': Wataru Yokojima (JP) and Joe Smith (EN)

The head of CTI. Owen suspects Eve is a Twisted, so he is constantly hostile towards her.

* BadBoss: There isn't a good reason for treating the one woman whom your entire operation and plan to save the world on like crap and calling her "thing".
* {{Jerkass}}: A bit of an understatement. [[spoiler:He kills the whole CTI team and tries to get Eve killed in a battle against Twisted-Gabriel]].
