!!Alexander J. Mercer/ZEUS

-->''"They call me a killer. A monster. A terrorist... I am all of these things."''

The protagonist, a man who [[WakingUpAtTheMorgue wakes up in the GENTEK morgue]] with [[LovecraftianSuperpower bizarre and horrifying powers]] and no knowledge of events prior to that point, aside from his name and that he was once a scientist. Confused, enraged, and determined to reclaim his past, he sets out to do so by hunting down his old colleagues.

[[spoiler:In truth, the creature acting as the protagonist is ''not'' Mercer but the Blacklight virus, which was released by the ''real'' Alex Mercer moments before he was shot dead and infected. The virus animated his corpse and came to believe it was him; however, evidence suggests that their personalities differ quite sharply.]] Voiced by Creator/BarryPepper in the first game and [[TheOtherDarrin Darryl Kurylo]] in the sequel.

* AxCrazy: it doesn't depend on whether you don't go after civilians or do, because either way, your target is gong to be subjected to a lot of homicidal fury which usually ends in the victim killed gruesomely or [[ImAHumanitarian being lunch.]]
* AloofBigBrother: [[spoiler:The real Alex only cared Dana as a tool for his purposes.]]
** [[spoiler: However, after Heller consumes Alex at the end of ''Prototype 2'' and absorbs his memories, Dana can be heard remarking that they used to play games, skate, and watch scary movies together. So, apparently he wasn't always like this.]]
* AmnesiacDissonance: [[spoiler:No matter how much of a monster you play Alex as, the man whose form he took was worse.]]
* [[spoiler: AndThenJohnWasAZombie]] One of the most horrifying examples ever put into a game or comic.
* AntiHero: Initially a straight-up VillainProtagonist, but becomes this status by the end of the first game due to CharacterDevelopment.
** NominalHero[=/=]UnscrupulousHero
* {{Badass}}: He is the protagonist of a SpiritualSuccessor to VideoGame/TheIncredibleHulkUltimateDestruction after all.
** BadassBookworm: In addition to being a former scientist, he absorbs the knowledge of anyone he [[ImAHumanitarian consumes]], and he'll consume upwards of thirty scientists completing the Web of Intrigue - though he doesn't exercise it much.
* BecomingTheMask: Played with. [[spoiler:The real Alex died; the player character is just TheVirus using him as a mask. But the virus has some redeeming qualities and is fiercely protective of Dana.]]
* BerserkButton: Lots of things, but especially don't hurt his sister or throw innocent people into his path to save yourself.
* [[spoiler:BiggerBad: The real Alex is not only responsible for the outbreak, he created the virus.]]
** [[spoiler:BigBadFriend: In the second game, as his sister, Dana, finds out.]]
* BigEater: Soldiers, civilians, infected, Hunters; he can and will absorb thousands of them alive (and in the humans' case, whole) throughout the game. One of the Achievements is even called Endless Hunger.
* BloodKnight: He actually seems excited at the prospect of fighting a whole pack of car-sized flesh monsters. The player will likely [[OhCrap disagree]].
* BodySurf: [[FaceStealer In his own way]], it's entirely possible to go undetected in a military base or during a mission by stealthily consuming and stealing the identities of one soldier after another. [[IThoughtItMeant This has nothing to do with the]] [[GrievousHarmWithABody Body Surf power]].
* CivvieSpandex
* CombatPragmatist: Fighting fair is hard when you can kill a person with one negligent gesture, so he doesn't bother.
* ClusterFBomb: Maybe it's a side-effect of eating all those soldiers.
* CreepyBlueEyes: His main distinguishing features are his unusually pale, creepy, reflective eyes.
* CursedWithAwesome
* DeadAllAlong: The shapeshifter tearing up Manhattan searching for his memories is [[spoiler: just the sentient Blacklight virus wearing Alex Mercer's corpse.]]
* DeadPersonImpersonation: Courtesy of eating them and taking their form.
* [[spoiler:DespairEventHorizon]]: [[spoiler: The prequel comics reveal the reason for his FaceHeelTurn in ''{{VideoGame/Prototype 2}}'' is because he [[HumansAreBastards lost all faith in humanity]].]]
* {{Determinator}}: The Blackwatch only ever manage to slow him down, even once he becomes their biggest threat and they throw everything they've got at him. Not because of his powers; he's just straight up ''too angry to quit''. Although being able to tear steel with his bare hands and survive rockets to the face doesn't hurt.
* DrivenToVillainy: Nobody ever asked ''him'' whether he wanted the powers he has, or whether he wanted to be treated like a monster. That he ''acts'' like one is in some sense a function of his circumstances, [[PlayingWithATrope at least at first]]. The trope is ultimately played straight, subverted, ''and'' inverted.
* EeriePaleSkinnedBrunette: The only colours in his face are the red circles under his eyes; even his lips are pale. He looks like he last slept when he was dead.
* [[spoiler:TheEmpath]]: [[spoiler:[[ImAHumanitarian In a very messed up way]], he absorbs so many people that their screaming in his head forces him to develop a conscience. He is extremely unhappy about that.]]
* [[EvenEvilHasStandards Even Anti Heroes Have Standards]]: As ruthless and violent as ZEUS is, even he was disgusted when he learned [[spoiler:what his creator did.]]
* ExtremeMeleeRevenge: The default animation for consuming a [[JigsawPuzzlePlot Web of Intrigue]] Target sees Alex knock his victim to the ground, pin them, and then just punch them viciously, over and over until their faces cave in. It's so brutal it even sprays blood on the camera.
* FaceStealer: The basis of his 'consume and become' abilities, along with BrainFood.
* [[spoiler:FourEyesZeroSoul]]: [[spoiler:The real Alex sported glasses prior to his death; the virus doesn't need them.]]
* [[spoiler:FreudianExcuse]]: [[spoiler:In his character profile ([[AllThereInTheManual and hinted at very obliquely in the game]]) is the story of Alex Mercer's horrible, poverty-stricken childhood being shipped around foster homes until his mother was released from jail. [[AbusiveParents He would have preferred the foster homes]], and eventually made his escape through his gift for science, viewing the high-profile job and excellent paycheck he received at GENTEK as owed to him by the world after his crappy life. When he learned that Blackwatch was going to purge the project, [[TakingYouWithMe that was the final straw]].]]
* FromASingleCell: Even after getting nuked, all he needs is a few scraps of his body and some biological matter and he's back in business.
* HatesBeingTouched: Quite minor, and for one scene, but Alex's reaction to Karen's welcoming embrace is to freeze uncomfortably and then shrug her off. [[PersonOfMassDestruction Understandably]], nobody else ever even tries to approach him with affection and he never approaches anyone likewise -- except once, [[MoralityPet with Dana]], [[PetTheDog trying to comfort her]].
* HijackingCthulhu: Is a viral abomination, but retains his human consciousness.
* [[spoiler: HumanoidAbomination: After TheReveal, it is revealed that [[TomatoInTheMirror he]] is a human-shaped pile of TheVirus that took the original Mercer's memories and form. You've been playing as TheVirus all along, with it ''thinking'' that he was Mercer. However even after this revelation, he still shares Mercer's form and protectiveness of Dana despite him not really being her brother.]]
* HurtingHero: He's clearly hurt by Dana's reaction upon seeing him killing a Blackwatch soldier, and then again to a greater (but more subtle) extent when he confesses that he can hear the voices of the people he's killed inside himself but believes that killing "feels right". He later apologises and she tentatively accepts him again [[spoiler:right before a Leader Hunter bursts through her wall and kidnaps her]].
* IdentityAbsorption: His baseline and most useful ability, though it's not without side effects [[spoiler:[[BeingGoodSucks such as developing a conscience]]]].
* ImAHumanitarian: He gains health, knowledge, powers, skills, disguises, and pieces of the JigsawPuzzlePlot by absorbing people.
* ImmuneToBullets: Functionally if not completely. Unless you're playing on Hard, it takes a lot of massed gunfire to even come close to damaging him. In cutscenes, he's able to get up from being shot by five guys armed with assault rifles and doesn't appear to be any worse off for the favor.
* InTheHood
* {{Jerkass}}: Selfish, vicious, violent, devoid of tact, almost ''hilariously'' bad at showing or receiving affection, and either borders on or is actively sadistic depending on the player. [[spoiler:The original Mercer went beyond "just" being a jerk, but his influence is likely at work.]]
** [[spoiler:JerkWithAHeartOfGold: Later, due to CharacterDevelopment.]]
* KillAndReplace: Or Consume And Become, same difference.
* KnightTemplarBigBrother: Mess with Dana and you better have a way out of Manhattan, because no place on the island is safe. You're not even guaranteed safety if you escape.
* LackOfEmpathy: [[spoiler:The original Mercer "wasn't ''paid'' to feel." He didn't.]]
* LightningBruiser: The only thing in the game that can keep up with him is an ''attack helicopter'', which he can kill in two hits. On the Infected side of things, Hunters and Leader Hunters are technically ''faster'', but suffer in maneuverability.
* [[spoiler:MadScientist]]: [[spoiler:Dr. Alex Mercer, at your service.]]
* MindHive: He keeps every one of his consumed victims' memories inside his head, and he says he can still hear them all screaming as he relives their deaths over and over and over.
* MorallyAmbiguousDoctorate: The certificate is on the wall of his apartment. [[spoiler:[[MadScientist And boy was he evil]]. Good thing we don't play as the guy who earned the doctorate.]]
* OhCrap: Seeing the two pathologists who were examining him get executed by Blackwatch, getting his cover blown infiltrating a Blackwatch announcement, and an unexpected Infected attack disrupting his plan to "interrogate" [=McMullen=]. Although, being Alex, his version of that last one is a little more M-Rated: '''"SON OF A ''BITCH!''"'''
* '''OneManArmy''': Within the city are [[KnightTemplar Blackwatch]], a merciless paramilitary organization aided by the U.S. Military, and a virulent, devastating, ZombieApocalypse causing virus, and both sides rightfully regard Alex Mercer as the ''single most dangerous thing there''.
* PersonOfMassDestruction
* [[spoiler:{{Plaguemaster}}]]
* [[spoiler:PresentAbsence]]: [[spoiler:Doctor Alexander Mercer's actions kick off the entire main plot and provide the motivations for at least two major characters, despite him being dead before the opening cutscene.]]
* PromotionToParent: According to the backstory, Alex was actually more of a paternal figure to Dana than their actual mother ever was.
* PsychoticSmirk: Alex never really smiles, but he's prone to these from time to time. Specific (and creepy) examples are after he thinks he's beaten Cross and [[spoiler:when he gets the drop on [=McMullen=]]].
* QuestForIdentity: His goal is to find out who he was before he lost his memory. [[spoiler:[[AwfulTruth Once he finds the truth, he immediately wishes he'd never learned it.]]]]
* RoaringRampageOfRevenge: His other goal.
* RogueProtagonist: In the sequel.
* RoofHopping: Due to a combo of LeParkour and InASingleBound.
* ShapeShifting: The entire basis of his powers that don't revolve around [[CannibalismSuperPower eating people]].
* ShapeshifterWeapon: In multiple flavors!
** AbsurdlySharpClaws: The first power Alex gained was four-fingered two-foot long talons.
** BladeBelowTheShoulder: The Blade.
** CombatTentacles: The Whipfist, Tendril Barrage, and Critical Pain Devastators.
** InstantArmor: The Armor.
** LuckilyMyShieldWillProtectMe: The Shield.
** MusclesAreMeaningful: The Musclemass.
** PowerFist: The Hammerfists.
** SpikesOfDoom: The Claws' groundspike move, and the Groundspike Graveyard Devastator.
** WolverineClaws: The Claws.
* TheSociopath: Mercer is diagnosed a [[ItsAllAboutMe narcissist]] and a [[SociopathicHero sociopath]] in one Web of Intrigue cutscene and the lack of a KarmaMeter - along with the sheer scope for destruction that his powers have and the way they're fuelled - means he'll be doing some awful things in the name of his goals. He rarely displays so much as a flicker of regret for the murder, ''mass''-murder, mass-cannibalism, all kinds of destruction, collateral damage... [[spoiler:However, {{subverted}} in that he ''does'' have regrets, even if only Dana and Cross ever see them. That diagnosis was more likely for the ''original'' Mercer.]]
* SpannerInTheWorks: [[CaptainObvious It turns out]] that a super-strong shape-shifting man-eating psychopath with an intense hatred for Blackwatch tends to screw up their plans. Funny how that works.
* TheStoic
** [[spoiler:NotSoStoic: During his confrontation with Colonel Taggart.]]
--->[[spoiler:'''Alex:''' '''COME BACK HERE, YOU FUCKING BASTARD!!''']]
* SuperSenses: Infected vision and Infrared vision.
* SuperStrength: Alex at a base level will kill humans in one hit and can lift cars. If you stack Musclemass on top of that, Alex can pitch cars over a city block and [[LudicrousGibs gib]] people in one hit.
* [[spoiler:TakingYouWithMe: The original Alex released Blacklight when he was cornered by the Blackwatch. it seems he didn't believe in half-measures - if he was going down, he was taking potentially ''the entire human race'' with him.]]
* ThereIsNoKillLikeOverkill: Alex is a guy who believes in being thorough. To the point of [[LudicrousGibs coating the ground, walls, and scenery with viscera]] in his, uh, enthusiasm.
* [[spoiler:TomatoInTheMirror]]: [[spoiler:Alex Mercer is hunting down the scientists behind the virus, including whoever caused the Penn Station outbreak. As it turns out, ''he's'' TheVirus. And the man who designed it and caused the outbreak? Alex Mercer.]]
* UnstoppableRage: His ground state of being. He's an angry, angry abomination against God, man, and nature.
* UnwittingPawn: Every bad guy manipulates him for their own gain at one point or another. He doesn't like it.
* VillainProtagonist
* WhatHaveIBecome: Word for word in his closing narration. His conclusion is that he is "less than human... but also something more."
* WrestlerInAllOfUs: Several of his normal moves. One of the default consume animations is a chokeslam.
* TheVirus
* [[WoobieDestroyerOfWorlds Woobie Destroyer Of Manhattan]]: You can't help but feel bad for [[spoiler:Blacklight-Alex a lot of the time. Surprise! You died. Surprise! You have no memory. Surprise! You unleashed a plague onto Manhattan. Surprise! YOU DID IT TWICE. (Although only the first time was intentional.) Surprise! You're not really you! Surprise! ''YOU'' ARE [[TheVirus THE VIRUS]]. Surprise! The original guy was evil! Surprise! You have a conscience now! Surprise! That means you feel like shit about ''everything''! Surprise! Your not-sister's been kidnapped! Surprise! The city's going to be nuked! The guy just can't catch a break.]] Granted, this is later subverted by [[spoiler:that very same conscience, which makes Alex decide that he doesn't want to make ''all'' of the people who get in his way die a horrible death because of his RoaringRampageOfRevenge after all. Just ''certain'' people.]]
* YoungerThanTheyLook: Alex looks to be in his late twenties [[spoiler:and indeed, the original Mercer was 29, but the viral copy is only 18 days old by the end of the game. He is, however, also ageless; he'll never look any older, either. As long as he keeps fed and whole, he could conceivably live forever.]]
* XMeetsY: In this interview [[http://cp.revolio.com/i/1161/71]], [[WordofGod Dennis Detwiller]] resumes Alex in "What if [[TaxiDriver Travis Bickle]] was ''Film/TheThing1982''?"


[[folder:Alex in Prototype 2]]

In the sequel, [[RogueProtagonist Alex is no longer the protagonist and differs a great deal in characterisation]], stemming from some bad experiences in between the games recounted in ''The Anchor''. '''Spoilers ahead.'''

* AGodAmI: Debatable in the sequel in accordance with his plan. He even tells his sister that the viral monsters are "no longer bound by life and death", and his MotiveRant includes a proclamation that he will create a perfect "new world".
* AffablyEvil: In the sequel toward Heller. He even tries to [[WeCanRuleTogether recruit him]] and teaches him how to absorb memories from his consumption targets. Testimony from his Evolved indicates he's genuinely fond of Heller, and he claims he's disappointed in him for disrupting his plans. Even when he makes the decision to ''kill Heller off'', he tries to give him a quick, clean, merciful death. It's only when that fails that the claws come out, and he never stops trying to convince Heller to join him.
* AllThereInTheManual: The comic book story ''The Anchor'' explains the reason for his FaceHeelTurn; after stopping the nuke, Alex lost faith in humanity and took to WalkingTheEarth in the hopes that he could find something to [[RestoredMyFaithInHumanity restore said faith]]. Instead, Alex just kept finding more and more reasons to think that HumansAreBastards, which culminated in a woman he had become attracted to stealing his money and shooting him point-blank in the face while openly declaring she only cared about herself. It was this that cemented Alex's change from fighting Blacklight to embracing it.
* BadBoss: [[spoiler:Berates his underlings during Web of Intrigue segments and consumes them all to boost his own powers]].
* BigBad
* [[spoiler:[[ZombieApocalypse Blacklight Apocalypse]]: His goal, expanded worldwide.]]
* BlueAndOrangeMorality: His goal borders on it, if not InsaneTrollLogic. Heller is...unconvinced by his arguments.
* [[spoiler:CainAndAbel: The Cain to Dana's Abel after his FaceHeelTurn.]]
* DarkMessiah: Has shades, given the reverence most of the evolved seem to hold him in. Many of them act honestly shocked that Heller is attacking them.
* DeadpanSnarker: His response to Heller's threat during the FinalBoss stands out:
-->'''James''': "You're gonna tell me [where Maya is], either on your own, or after I skull-fuck you and drain your memories out the hole!"\\
'''Alex''': ''(chuckles)'' "[[SarcasmMode Scary!]]"
* DevourTheDragon: [[spoiler:Before throwing down with Heller]], he consumes all the Evolved present to boost his own power and go OneWingedAngel.
* TheDreaded: Unsurprisingly, given all the chaos he caused and is still causing; at the beginning of the game, Red Crown's response to learning Alex is in the Red Zone is a very justified "[[OhCrap Oh, shit!]]"
* {{Expy}}: In the sequel, the similarities to long-standing Franchise/ResidentEvil villain Albert Wesker (particularly his characterization in ''VideoGame/ResidentEvil5'') are too numerous to ignore. Both are intellectual, with scientific backgrounds (though Mercer's are borrowed), who started an endemic with a weaponized virus, who wish to wipe the scourge of humanity with a bioweapon of mass destruction, are extremely dangerous warriors augmented with the same virus they plan to use to wipe out the planet, and all of the aforementioned viruses result in veiny, bulbous, tendrily, organic shapeshifting monsters. Both have a FemmeFatale businesswoman associate whom they betray towards the end of the game. They even have a similar mode of speech and a tendency to keep their [[RedEyesTakeWarning red eyes]] hidden.
* FaceHeelTurn
* [[spoiler:FamousLastWords[=/=]FacingTheBulletsOneLiner: "[[ThisIsGonnaSuck Huh.]] [[GracefulLoser Welcome to]] [[SocialDarwinist the top of]] [[CannibalismSuperpower the food chain.]]"]]
* [[spoiler:GracefulLoser: Though he throws everything he's got at Heller in the final battle, he faces death congratulating Heller for becoming the strongest of all the Evolved.]]
* [[spoiler:[[HiveQueen Hive King]]: In ''Prototype 2'', he has taken Elizabeth Greene's place as the leader of the Infected.]]
* JumpingOffTheSlipperySlope: Hoo, boy.
** He infects Heller, which Heller views as a curse.
** [[spoiler:Ordered his Evolved to sabotage a cure for the virus.]]
** [[spoiler:Said sabotage involves retooling it to spread the virus even ''further.'']]
** [[spoiler:In fact, the second outbreak was ''entirely his doing''.]]
** [[spoiler:Murders Father Guerra in cold blood to screw with Heller.]]
** [[spoiler:[[KickTheMoralityPet He's driven Dana off to the point where she doesn't see him as her brother any more.]]]]
** [[spoiler:Nonchalantly [[DevourTheDragon consumes his disciples (including Sabrina Galloway)]] to boost his own power for the final boss fight.]]
** [[spoiler:And finally, he tells Heller ''to his face'' that he intends to make Amaya the next Evolved so that she can create more.]]
* [[spoiler:KilledOffForReal: Is consumed by James Heller in the final mission.]]
** [[spoiler:HoistByHisOwnPetard: After he consumes his remaining Evolved, he is consumed in turn by Heller.]]
** [[spoiler:KarmicDeath: He shouldn't have kidnapped and tried to infect Heller's daughter. He could have survived if he hadn't.]]
** [[spoiler:PyrrhicVillainy: He really didn't need to take [[PapaWolf Heller's]] daughter in order to fulfill his plan, and this was, in the end, what got him killed, not that his EvilGloating helped.]]
* KickTheDog: [[spoiler:Killing Guerra.]]
* LargeHam: He is ''much'' more animated this time around - gesturing grandly and making more of a meal out of his ''lines'' than his actual meals (which he seems to have given up).
* ManipulativeBastard: He has infected numerous individuals, called Evolved, with his strain of the Blacklight Virus and planted them in high-ranking positions in Blackwatch and Gentek to serve as spies. He also tries to manipulate James Heller into helping him out, but makes a crucial mistake that clues Heller into his real motives - mentioning that together they will destroy Gentek and Blackwatch... [[ExactWords but not the virus.]]
* MotiveRant: Has one. [[ShutUpHannibal Heller doesn't really care.]]
* [[spoiler:NotSoDifferent: Remember his disgust with Greene and his original incarnation? His actions in the sequel are near-identical to theirs. He even returns to Penn Station where the original Mercer was shot dead to release the virus ''a second time'', apparently in the name of drama.]]
* NoPlansNoPrototypeNoBackup: Heller, he teaches him the ropes of his new powers and expects him to join the other Evolved. It seems he didn't even factor in what would happen if Heller, or any other Evolved went rogue and fought against him.
* NoSenseOfPersonalSpace: In his cutscenes with Heller (and in contrast with the first game), he has a habit of putting his hands on Heller's shoulders or chest as a means of seeming more sincere.
* [[spoiler:OneWingedAngel: He spends most of the game appearing outwardly human, but when push comes to shove and after consuming the Evolved, his body becomes significantly more monstrous. Along with his old {{Shapeshifter Weapon}}s distorting his form, his limbs become bloated and discoloured, spines erupt from his back, he's covered in blood, and his eyes glow red.]]
* PetTheDog: Quite nice to Heller, at first - teaching him how to consume targets and gain memories from them and informing him that consuming the more monstrous Infected will give him new powers. He also [[spoiler:never actually goes so far as to kill [[MoralityPet Dana]] even when she's trying to disrupt his plans wherever possible. Before his final fight with Heller, he hides both Dana and Amaya safely out of the crossfire.]]
* RedEyesTakeWarning: His eyes turn red [[spoiler:during his fight with James Heller.]]
* SocialDarwinist: He believes the "[[HumanoidAbomination Evolved]]", especially himself and Heller, are at the top of the food chain.
* SuddenSequelHeelSyndrome: Went from a conflicted, guilt-ridden AntiHero at the end of Prototype to a megalomaniacal supervillain just in time for the next game.
* SnarkToSnarkCombat: In [[spoiler: the final battle]], Mercer and Heller hurl insults back and forth.
--->'''Alex:''' "Hey! ''I'm'' using that!" [[spoiler:(said if Heller uses the same weapon as him)]]
* [[spoiler:TakeOverTheWorld: His goal in ''VideoGame/{{Prototype 2}}'' amounts to turning the human race into Evolved under his command in order to end all conflict.]]
* ToThePain: Vows this against Heller after failing to kill him:
-->'''Alex''': "It would've been quick. But now... I'm gonna make you ''suffer''."
* [[spoiler:VillainForgotToLevelGrind: Implied. Alex has since then given up fighting in favor of raising an army to oppose humanity. This was especially evident during the final confrontation between him and Heller, instead of attacking head on and gang up on him with his fellow Evolved, he absorbs them to make himself strong enough to fight. In fact, if one were to get use to the fight with Mercer, he's not really that much of a threat. Also, when Heller foils one of his plans, he never attempted to execute him and instead kills Guerra.]]
* WalkingTheEarth: Does this between games. He was very, ''[[FaceHeelTurn very]]'' [[KillAllHumans disappointed]] in what he saw.
* WellIntentionedExtremist: His actions in the sequel are legitimately in order to end the stagnation and cruelty of humanity [[spoiler:by killing most of it off and forcing the rest to become something... [[HumanoidAbomination else]]]]. He's just... [[KnightTemplar rather extreme about his methods]].
* [[spoiler:WouldHurtAChild: Makes explicit his intention to infect Amaya ''in front of Heller''. [[BlueAndOrangeMorality He doesn't see it as 'hurting' her]], and [[PetTheDog specifically made sure she'd be safe during the final battle]], but if it'll piss off his opponent and cause him to start making mistakes... hey, whatever works.]]
[[/folder]]

!!Dana A. Mercer

-->''"Someone's gotta know what the fuck is going on here."''

Alex's younger sister and the first person he remembers after he awakes. A journalism student and spitfire with a sharp tongue and an inquisitive mind, she loves and idolises her older brother, despite not having seen him in five years, and acts as his intelligence gatherer and data analyst. Voiced by Lake Bell in the first game, and Lindsay Ames in the sequel.

* [[spoiler:CodeName: "[[ClassicalMythology Athena]]" in ''VideoGame/{{Prototype 2}}''.]]
* DistressedDamsel: A few missions revolve around rescuing her from peril. Pretty understandable, since she's not the one with superpowers.
* EeriePaleSkinnedBrunette: But only because she's always in the dark. She'd probably look normal in good light.
** In ''2'', she takes issue with being called "pasty".
* [[spoiler:[[EtTuBrute Et Tu, Alex?]]: Definitely her reaction in the second game when Alex imprisons her inside a bank vault with Amaya.]]
* [[spoiler: [[IHaveNoSon I Have No Brother]]: Tells Heller to kill Alex after finding out he had Galloway kidnap Amaya, as he is no longer her brother, and explicitly tells Alex as he stuffs her and Amaya in a bank vault that Alex is "dead now."]]
* ITakeOffenseToThatLastOne: In ''Prototype 2'', a bunch of drunken soldiers call her and Heller up and insult them, calling Dana a "pasty hacker cunt." Afterwards, Dana grips that she's "not pasty."
* IntrepidReporter: Only a student, but according to her character profile, she's naturally inclined this way.
* LadySwearsALot: Though the entire game is hardly stingy with the F-bombs, she swears as often as the ''soldiers'' do.
* MissionControl: You get most of the story missions for the first part of the game from her. [[spoiler:Continues this tradition with Heller in the sequel after Guerra dies, for approximately the second half of the game.]]
* MoralityPet: The only living being that Alex gives a damn about aside from himself. Also one of very few people in the game on speaking terms with stuff like ethics and sanity. [[spoiler: Likewise, She is Heller's only friend and the only person he makes an effort to be nice to after Guerra's death.]]
* NowWhat: [[spoiler: How she ends the second game. "What do we do now?"]]
* ParentalSubstitute: Her character profile explains that this is the reason she trusts her older brother so absolutely; never knowing her father, Alex was the closest thing she had to a stable parental figure. [[spoiler:Knowing this makes [[MadScientist everything]] [[ItsAllAboutMe revealed]] [[TomatoInTheMirror about her brother]] roughly a bazillion times more depressing.]]
** [[spoiler: Heller tries to convince her to take Amaya in if Heller is somehow not around. Though Dana's flustered, she and Amaya get along very well, and Amaya runs towards Dana when Heller's infection freaks out Amaya.]]
* PluckyGirl: Not that it does her any good [[CrapsackWorld given the setting]], but this college-age girl with no combat training and no superpowers insults the Blackwatch to their faces and actually ''headbutts'' one who put his hands on her. That Alex splatted the guy a second later in no way lessens her sheer chutzpah. On the optimism count, she never turns her back on her brother, always helping him even when he's just gotten through explaining that ''he eats people'', in the sincere belief that he's still in there somewhere and knows what's right. [[spoiler:She's wrong on both counts -- about her real brother. Her fake one, oddly enough, is less of a bastard and genuinely cares.]]
** [[spoiler:Far less optimistic in the sequel, considering what her [[IHaveYourWife fake]] [[BigBad brother]] [[WellIntentionedExtremist becomes]]. Still ends up relatively okay, though.]]
* ScarfOfAsskicking: Sports one in the second game.
* [[WhatHappenedToTheMouse What Happened to the Mouse?]]: [[spoiler:Rescued while unconscious, not seen again for the rest of the game.]]
** [[spoiler:She does show up in the sequel, however, as "Athena", Heller's contact and second MissionControl.]]

!!Karen Parker

Alex's ex-girlfriend and a scientist like him; her picture still hangs on the wall of his apartment. She helps him create a cure for the virus ravaging Manhattan. [[spoiler:One of the viruses, anyway. Specifically, Alex himself; Karen was (possibly) forced into working for Blackwatch and the "cure" turns out to be a parasite designed to kill him.]] Voiced by Creator/VanessaMarshall.

* [[spoiler:DarkChick]]: [[spoiler:For Blackwatch.]]
* FemmeFatale
* HotScientist
* [[spoiler:KilledOffForReal]]: [[spoiler:Not explicitly done ingame (though heavily implied), but in promotional materials for the sequel, they reveal that Mercer killed her.]]
* [[spoiler:TheMole]]
* MorallyAmbiguousDoctorate

!!Doctor Bradley Ragland

-->''"My medical opinion's not for sale."''

A pathologist who knows some uncomfortable secrets, content to run the morgue in a teaching hospital in New York. He once worked for GENTEK, but quit on ethical grounds some time ago. Dana sends Alex to him [[spoiler:in the hopes that he can cure the parasite.]] Voiced by Creator/PhilLaMarr.

* MorallyAmbiguousDoctorate: Good, but worked with [=McMullen=] in the past.
* OnlySaneMan: The ''other'' character with a working sense of ethics.
* [[WhatHappenedToTheMouse What Happened to the Mouse?]]: [[spoiler:Alex leaves Dana in his care, and they both are not seen or heard from again afterwards. Unlike Dana, his fate is not alluded to in the sequel.]]

!!Director Raymond [=McMullen=]

-->''"I want [[ItIsDehumanizing it]] [[StrappedToAnOperatingTable on a slab]]. [[PlayingWithSyringes I need to know what makes it tick.]]"''

The Director of Research at GENTEK; Alex's ex-boss, who knows more of Blackwatch's secrets than is healthy due to his insatiable scientific curiosity. This fascination extends to Alex's abilities [[spoiler:and eventually leads to his death]]. Voiced by Paul Guilfoyle.

* [[spoiler:BetterToDieThanBeKilled: Especially when your enemy will gain vital information by killing you.]]
* CorruptCorporateExecutive
* EvilGenius: For Blackwatch.
* FourEyesZeroSoul
* [[spoiler:GoOutWithASmile: He smirks at Alex just before blowing his own brain out.]]
* MadScientist: A subdued one, but he ''really'' wants to learn about TheVirus, to the point that his curiosity gets him in trouble with Blackwatch because he keeps finding out things that they don't think he should know.
* MorallyAmbiguousDoctorate: Yes, another one. He's evil.

!!Captain Robert Cross

-->'''Soldier''': Is it true that he caught the last [[PersonOfMassDestruction Runner]] on his own?
-->'''Randall''': Not caught. [[DidYouJustPunchOutCthulhu Killed]].
---> - Discussing [[{{Badass}} Cross]]

A highly skilled and dedicated member of Blackwatch who believes wholeheartedly in what they claim to fight for: protecting the American people from the threat presented by the virus, whatever it takes. He has a reputation for surviving and winning battles with even the most powerful infected creatures. Voiced by Jeffrey Pierce.

* ArmCannon: Sports an arm-mounted grenade launcher.
* BadassNormal: He fights Alex Mercer to a very close loss and walks away alive thanks to being CrazyPrepared.
* CrazyPrepared: He uses Alex's ''flashbacks'' against him. [[spoiler:Unfortunately, it doesn't save him from the Supreme Hunter.]]
* TheDragon
* [[spoiler:EvenEvilHasStandards: Since [[NukeEm Operation Firebreak]] was [[NotWhatISignedOnFor not what he signed on for]], he pulls a HeelFaceTurn and tries to help Alex take down Blackwatch.]]
* GoodIsNotNice: Cross might be significantly less insane than the rest of his division, but he's Blackwatch to the core. He'll throw men at Mercer to whittle him down, [[spoiler:speak worryingly casually about helping Mercer eat his superiors, and while 'allied' with Alex tries pretty hard to get him killed]]. All for the greater good, but yeesh.
* GreenEyes: It's hard to tell because of colour issues, but [[AllThereInTheManual his character profile]] lists them as green. More to the point, his eyes are important because he is the only front line Blackwatch officer to leave them uncovered, [[spoiler:humanising him for an eventual HeelFaceTurn]].
* GuileHero [[HeroAntagonist Antagonist]]: It may be a bit of a stretch to call him a hero at first, but he does manage to nearly defeat the VillainProtagonist [[PersonOfMassDestruction Alex]] [[spoiler: simply by [[TalkingTheMonsterToDeath talking to him and triggering his memories]].]]
* [[spoiler:HeelFaceDoorSlam: Cross gets eaten by the Supreme Hunter well before he and Alex can stop Blackwatch.]]
* [[spoiler:HeelFaceTurn]]: Caused by [[spoiler:the General's plan to nuke Manhattan]].
* InspectorJavert: He's the soldier specifically tasked to capture Alex Mercer, but the motives for his SternChase initially avoid sympathy as they are dictated by [[WellIntentionedExtremist Blackwatch]]. [[spoiler: True to the trope description, he [[HeelFaceTurn redeems himself]] when he teams up [[EnemyMine with Alex]] to stop Blackwatch from [[ScrewTheRulesImDoingWhatsRight nuking Manhattan]].]]
* LightningBruiser: Though the shock baton admittedly represents much of his damage potential, this man can dodge every blow Mercer throws at him so long as he isn't setting up for an attack with his arm-mounted grenade launcher.
* ManipulativeBastard: [[spoiler:A close examination of Cross's late-game actions reveals that he plays Mercer like a ''fiddle''.]]
* [[spoiler:NotWhatISignedOnFor]]: Which prompts his [[spoiler:HeelFaceTurn]].
* ShockAndAwe: He carries around an electric baton that can seriously hurt Mercer.
* SkunkStripe
* [[SwordDrag Taser Drag]]: Does one [[spoiler:when staring down the Supreme Hunter, from its perspective.]]
* YoungerThanTheyLook: He's thirty-eight. Really.

!!General Peter Randall

-->'''Alex''': [[EvenEvilHasStandards Even Randall's not crazy enough]] [[NukeEm to nuke]] [[BigApplesauce Manhattan.]]
-->[[spoiler:'''Cross''']]: [[TheUnfettered You're wrong.]]

The current leader of Blackwatch, directing their movements in Manhattan. He has been in the organisation long enough to remember Hope, Idaho, and the methods used to contain it. Voiced by Gordon Clapp.

* ArmiesAreEvil
* AuthorityEqualsAsskicking: [[SubvertedTrope Not really]]. It's expected, since he's been fighting the virus virtually for his entire career and it was because of his orders and determination that Hope's infection didn't spread, but that was forty years ago when he had both arms. [[spoiler:And indeed, when Alex finds him, he doesn't even go down with a fight.]]
* BigBad
** [[spoiler:CutsceneBoss]]: [[spoiler:When Alex finally catches the bastard, he grabs Randall, yells at him, and throws him down before casually eating him in a cutscene. Considering Alex's [[PersonOfMassDestruction power]] by that point, the alternative was probably a ZeroEffortBoss.]]
* GeneralRipper: Randall wants to fight the virus however he can. If that means shooting innocent people, sending his men to die in a hopeless war, slicing his own infected arm off with a butcher's knife, [[spoiler:''[[NukeEm nuking Manhattan]]'' and [[TheScapegoat blaming the]] [[SemperFi United States Marine Corps]], or putting the virus in a position where it would do a huge amount of damage when it escaped to learn how to engage it properly]], he will do it.
* KnightTemplar
* TheUnfought: You don't really fight him, but [[spoiler: you automatically gain his memory node after the the cutscene.]]
* WellIntentionedExtremist: He says outright that he believes all casualties of any outbreak and resultant purge are "sacrificial lambs" necessary to learn how to fight the infection and "save the world" [[spoiler:and may or may not have deliberately engineered the catastrophe that was the Manhattan outbreak, just to learn how to fight the virus on a larger scale]]. That this outlook and method are ''balls crazy'' [[spoiler:and result in things like nuking Manhattan only ''after'' Greene is dead and the infection is weakening (because she couldn't then be retrieved for further study)]] seems not to occur to him.

!!Colonel Ian Taggart

The leader of the Marines in Manhattan and Randall's second-in-command. Voiced by Richard [=McGonagle=].

* TheBrute: Although he doesn't look muscular...
* DirtyCoward: Or at least Randall and Alex think so [[spoiler:when he finally snaps and tries to withdraw]]. [[ZombieApocalypse But it's hard]] [[PersonOfMassDestruction to blame him]].
* GetBackHereBoss: He spends most of the time running away from you in his tank, while occasionally stopping to take potshots with its thermobaric cannon.
* OnlySaneMan: In contrast to the above, he realizes right off the bat that both Blackwatch and the Marines are in no position to handle this threat, but Randall won't let him retreat.
* VillainousBreakdown: As the situation deteriorates, he tries to get Randall to deal with the problem at a distance. When Mercer comes for him, he panics and abandons his men.
** Clarification: he ''places'' his men between him and the pissed off HumanoidAbomination coming to eat him.
* WeHaveReserves: He begins throwing his troops into Mercer's path and certain death to gain time to escape himself. It fails. But on [[SarcasmMode the bright side]], he ''did'' succeed in making [[HorrifyingHero Mercer]] [[BerserkButton really, really angry]]. [[spoiler:He also wanted to perform [[NukeEm Operation Firebreak]] on Manhattan from the very beginning in order to wipe out the infection from a distance, thereby exhibiting this idea for the ''[[MoralEventHorizon enter population of civilians and other soldiers operating there]]''.]]

!!Elizabeth Greene/MOTHER

-->'''Alex''': [[WhatTheHellAreYou What are you?]]
-->'''Greene''': The reason.
-->'''Alex''': For ''what''?
-->'''Greene''': Everything!

The last surviving inhabitant of Hope, Idaho, a town that was destroyed after being used as a testing ground for a biological weapon, to prevent the disease from spreading. She appears 'burnt out' and catatonic after forty years of experimentation by GENTEK. [[spoiler:There is almost certainly no remnant of 'Elizabeth Greene' left; all that remains is the virus in an empty human host. Unfortunately, it is both intelligent and very patient.]] Voiced by KariWahlgren.

* AxCrazy: There's nothing human left in her any more. [[AndIMustScream We hope.]]
* BigBad
** [[spoiler:DiscOneFinalBoss: Her death doesn't end the game ''or'' the infection, though it does slow the infection quite a lot.]]
* BrownEyes: A subversion of the usual symbolism. Greene is not in the least bit down-to-earth or stable.
* CuteBruiser: Though the 'cute' part is up for debate, she hits Alex ''once'' and he's ''smashed across the room''. This is a guy who weighs hundreds of pounds slapped aside like a cardboard cutout.
* DecoyDamsel: [[PlayingWithSyringes GENTEK]] thinks they've contained her, and they're wrong. She's just waiting patiently to unleash the ZombieApocalypse.
* EvilMatriarch
* HiveQueen: Without a Runner like Greene [[spoiler:or other directing force such as the Supreme Hunter or Alex]], the lesser Infected remain mindless shambling zombies. However, ''with'' a Runner, {{it can think}}...
* HumanoidAbomination: She still looks like a 19-year-old girl. She and Alex share many similarities (strong, fast, resilient, power over the virus) [[spoiler:but aren't quite the ''same''. Only Greene was once human]].
* ItCanThink: And it is ''patient''. If it's four years or forty years, the virus will wait in dormancy as long as it takes an opportunity to present itself, and during all that time, it plans. One mission revolves around Greene using infected people who haven't started showing symptoms as unwitting spies, their connection to the HiveMind allowing her to receive information from them. [[spoiler:After she dies, the outbreak loses its momentum almost completely.]]
* LatexSpaceSuit: Her clothing is outright modelled on fetish clothing and wet-suits, resulting in a skin-tight latex body suit with a lot of straps in weird places.
* LivingBodysuit
* MakeMeWannaShout: In her boss fight, one of her attacks is a scream that sucks the colour from the screen and sends shockwaves over the battlefield that will knock you down to critical health if you don't move your butt.
* [[spoiler:NotSoDifferent: From Alex. This is especially played up when Alex [[{{Plaguemaster}} takes her place]] in the sequel.]]
* OlderThanTheyLook: She looks nineteen. She's actually over fifty.
* [[spoiler:OneWingedAngel PoweredArmor: Though it's possible she could have taken Alex in melee given the strength she demonstrates in the cutscenes, instead she dons a giant fleshy mass as armor and starts tearing everything around her apart. [[MarathonBoss It takes a lot to bring her down.]]]]
* {{Plaguemaster}}: The virus spreads on everything she touches, and the [[DegradedBoss Hunters]], [[DemonicSpiders Leader]] [[MiniBoss Hunters]], and [[CombatTentacles Hydras]] are her creations.
* SealedEvilInACan: Or an observation cell. Then Alex accidentally lets her out. To be fair, she clearly could have left at any time, given the state of the room.
* WalkingWasteland: Everywhere she goes, the infection emerges, and [[ZombieApocalypse her children]] follow.
* TheVirus: By some quirk of biology, her body was mutated by the original strain to ''create'' viruses; hundreds of them. Every single one displays very strange properties. Gentek's reason for holding her is to examine and try to manipulate the strains into doing useful things, such as enhancing human attributes, killing people in specific ways very very rapidly, strengthening immune systems, or eradicating cancer, among other purposes. She's insanely valuable to Blackwatch because she is the only living subject to display the ability.
* VoiceOfTheLegion: After she speaks, her words are repeated in multiple whispers.

!!The Supreme Hunter

[[spoiler:After Alex removes the parasite, he attempts to kill Greene by using it on her, but her body rejects it. The result combines Mercer's and Greene's DNA and becomes something new: a creature with characteristics of both the Redlight and Blacklight viruses. It is ''not'' happy with its 'father' for attempting to destroy it.]]

* TheDragon: To Greene.
** [[spoiler:DragonAscendant]]
* EvilCounterpart: To Alex - roughly humanoid, just as smart (or smarter), [[spoiler:same powers, and an independent entity, born from the virus and Elizabeth Greene but not under her thrall, just like Alex]]. Unlike him, it wants to control and spread the disease and it isn't even a little bit human.
* KillAndReplace: [[spoiler:Cross.]]
* [[spoiler:SelfMadeOrphan]]: [[spoiler:First, it doesn't seem terribly distressed about Alex killing and absorbing Greene, its genetic 'mother'. Second, its purpose in life is to kill and devour Alex -- implied to be at least in part because it ''resents'' him for ''not letting himself be eaten alive''.]]
* HumanoidAbomination: Especially [[spoiler:when it consumes and replaces Cross.]]

!!PARIAH

[[spoiler:Of all the children born during Hope, Idaho's infection, only one did not suffer fatal defects within months of birth. Codenamed PARIAH by the military, the surviving child was forcibly separated from his mother, Elizabeth Greene, and moved to a secure facility for study and containment. He never appears in the game, but plays a fairly large part in the Web of Intrigue.]]

* BishonenLine: [[spoiler:PARIAH shows no sign at all of infection with the virus, and yet [=McMullen=] theorises that he could bring about the end of life as we know it.]]
* BlessedWithSuck: Seems to kill anything he touches. As a result, he is kept either in a sealed cell or a courtyard surrounded by snipers and barbed wire.
* CreepyChild: [[spoiler:There are three pictures of him. One is him playing with a ball, one is him playing with blocks, and the third is him ''standing beside a mutilated corpse with a handful of blood''. What ''is'' this kid?]]
* PersonOfMassDestruction: [[spoiler:It's theorized by [=NPCs=] that if Alex Mercer and PARIAH ever came in contact with each other, the results could be beyond catastrophic.]]
* SuperPrototype: [[spoiler:In a way, ''Alex'' is the production model of what PARIAH is naturally, and probably isn't even as good. His powers were artificially activated, whereas PARIAH's are natural; PARIAH is everything the virus is meant to be.]]
* OlderThanTheyLook: [[spoiler:He must be at least forty, but he looks no older than six or seven.]]
* SequelHook: [[spoiler:Averted in the second game; the sequel doesn't involve Alex looking for him. He is mentioned once as the assignment of [[TheMenInBlack Agent Barnes Griffin]], and otherwise seems to have no bearing on events. But he's still out there...]]
