History Characters / TheCallistoProtocol

* AncientConspiracy: [[spoiler:Is a part of one called the Commonality, that's been trying to guide the humanity's development for centuries.]]

* BigBad: He's the man in control of the HellholePrison Jacob and his allies are trying to escape from, and [[spoiler: also turns out to be responsible for causing the Biophage outbreak as well]].
* CannedOrdersOverLoudspeaker: Black Iron is peppered with his prerecorded holographic addresses to prisoners. [[spoiler:Which is played for a minor spook once, when a hologram turns out to be a direct message to Jacob instead.]]
* EvenEvilHasStandards: [[spoiler:Inverted, in that Cole is the one who has less standards compared to other evil characters. Both Mahler and his fellow Circle members think he's going too far in his methods.]]
* EvilutionaryBiologist: [[spoiler:Cole seeks a way to improve humanity's physical form, and sees the biophage as a potential way to do this. For this reason he causes the biophage outbreak in Black Iron in order to find his Alpha, because "evolution does not happen in the lab" (notably, Mahler, who is an actual scientist, scoffs at this viewpoint).]] He also [[spoiler:believes in the evolution as "survival of the fittest", which is why he wants Jacob alive as the exemplar of humanity's will to survival, in order to have him fight his Alpha and through that find out which form is superior.]]
* IWantThemAlive: Cole wants Jacob captured alive [[spoiler:once he sees him as the perfect manifestation of mankind's survival instincts. Sadly, his Alpha does not care, and both times you fight him it's to the death.]]

* WellIntentionedExtremist: Despite his terrible actions, [[spoiler: including causing the biophage outbreak,]] he does have genuinely good intentions. [[spoiler: He honestly believes that the only way humanity can survive outer space is by forced evolution to make themselves strong enough to endure harsher environments.]]

* TheAtoner: [[spoiler:In the present. Seeing how far Cole is willing to take the biophage project, she decides she's had enough and turns against him, helping Jacob behind Cole's back.]]

* HeelRealisation: [[spoiler:Has one after hearing how Cole considers the Europa outbreak a revelation and an opportunity.]]
* ForScience: [[spoiler:Her original motivation, in her recordings she gleefully speaks of wonders and potential applications of the biophage pathogen to enhance the humanity, and does not mind conducting experiments on living humans to unlock those applications.]]
* ALighterShadeOfBlack: [[spoiler:Compared to Cole. She's still an amoral scientist who experimented on humans and had possibly knowingly sent another science team to their deaths to survey the old colony, but unlike Cole she considers the Europa outbreak nothing but a tragedy, and turns against him after Cole replicates it in Black Iron.]]
* MorallyAmbiguousDoctorate: She outfits Jacob with the CORE implant after he had been unlawfully incarcerated at the start of the game without batting an eye, and that's just the tip of the iceberg.

Expy: Of the Exploder Necromorph from Dead Space, fulfilling the same role

* Expy: Of the Exploder Necromorph from Dead Space.

* OrificeInvasion: If you fail to shake them off in time they will infect Jacob and kill him - by physicaly crawling into his mouth and throat.

* NooneCouldSurviveThat: After Ferris gets tackled through the control tower's window Jacob assumes that that is the end of him. He assumes wrongly.

* ContractualBossImmunity: He's immune to the [=GRP=] as well as to the block-breaker and counter-attack upgrades to the stun baton.

* ChekhovsGunman: She briefly appears during the prologue to forcefully outfit Jacob with his CORE implant and vanish for most of the game save for prerecorded logs, only to reappear almost at the end with a much bigger role.

* MorallyAmbiguousDoctorate: She outfits Jacob with the CORE implant after he had been unlawfully icarcerated at the start of the game without batting an eye, and that's just the tip of the iceberg.

* NonIndicativeName: Based on their name you'd think they'd be able to convert humans into Biophages, similar to the Infectors from ''Dead Space''. Nope, it's the Big Mouths that do that. Based on the areas you encounter them in, the Corruptors seem to be responsible for creating the MeatMoss in Biophage-infected areas, corrupting the ''environment''.

* AchillesHeel: Their blindness. They will fail to notice Jacob even if he is standing right in front of them as long as he's not making any noise, and while they are very dangerous in the open combat they can still die to a single stealth takedown.

* EliteMooks: They hit very hard and are extremely resilient themselves. Engaging them in a straight fight is more trouble than its worth, so it's better to sneak around them.

A crawling biophage creature covered in caustic pustules

A larger biophage creature seemingly consisting of multiple human bodies melded together into a single organism. Unlike most other mobile biophages they prefer ambushes to direct attacks.

* DegradedBoss: The first time you meet one it is preceded by a cutscene and it is dealt with in a one-on-one fight. The second one also has a cutscene but it's shorter and in its fight it is supported by regular grunts. Your third encounter with the two-heads has no fanfare at all, and after that you begin stumbling onto multiple of them at once.

* GiantMook: It is the biggest biophage creature [[spoiler: except for the FinalBoss]], towering over Jacob and with a bulk to match.

* ImmuneToBullets: Played straight in his first form. Jacob's ranged attacks only briefly daze him at best, but mostly just piss him off. Even in his second form only his head is vulnerable, and he covers it.

* EvilutionaryBiologist: [[spoiler:Cole seeks a way to improve humanity's physical form, and sees the biophage as a potential way to do this. For this reason he causes the biophage outbreak in Black Iron in order to find his Alpha, because "evolution does not happen in a lab" (notably, Mahler, who is an actual scientist, scoffs at this viewpoint).]] He also [[spoiler:believes in the evolution as "survival of the fittest", which is why he wants Jacob alive as the exemplar of humanity's will to survival, in order to have him fight his Alpha and through that find out which form is superior.]]

* CameBackWrong: Due to the nature of the Biophage [[spoiler: the individuals no longer resemble their previous selves. In some cases they don’t even resemble the same ''species''.]]
* TheHeavy: Collectively, they're the main obstacle Jacob must wade through to escape Black Iron, with [[BigBad Warden Cole]] being the architect behind the outbreak.
* HitAndRunTactics: While most Biophages are melee berserkers limited to AttackAttackAttack, one quadruped, wallcrawling variant uses hit-and-run tactics instead, pouncing on you then quickly retreating into vents or the ceiling.

* ItCanThink: Certain members tend to understand the melee variations can occupy Jacob while can sit back and take shots from afar. It’s also common for them to ambush the player. Also, if you try to funnel a group of Biophages into a narrow space to try and fight them one at a time, the front Biophage will often just grab you and throw you so you end up in the middle of the entire group where they can all attack you from every direction.

* MadeOfIron: [[spoiler: Many of the mutants don’t even flinch if you shoot them.]] Heck the bosses don’t notice if you shoot them.

* DegradedBoss: A group of them is first encountered as a boss fight in the sewage control room, but later you start running into them on a more regular basis.

* EvilutionaryBiologist: [[spoiler:Cole seeks a way to improve humanity's physical form, and sees the biophage as a potential way to do this. For this reason he causes the biophage outbreak in Black Iron in order to find his Alpha, because "evolution does not happen in the lab" (notably, Mahler, who is an actual scientist, scoffs at this viewpoint).]] He also [[spoiler:believes in the evolution as "the survival of the fittest", which is why he wants Jacob alive as the exemplar of humanity's will to survival, in order to have him fight his Alpha and through that find out which form is superior.]]

* CelingCling: They can move across walls and ceilings just as easily as they do over the floor.

* LosingYourHead: Most can and will not react if you do.

[[folder:Corruptor]]

A mutated human that carries the Biophage and continues to transmit it to other viable hosts.

* GameplayAndStorySegregation: Of course, they very conveniently jump at Jacob's shoulder first instead of [[spoiler:going for his face like they do Dani, allowing Jacob to remain uninfected during the course of the game.]]

* ItCanThink: Certain members tend to understand the melee variations can occupy Jacob while can sit back and take shots from afar. It’s also common for them to ambush the player.

* EliteMooks: They're a step up from the fat mutants and mutated security guards, and are the largest and toughest Biophage enemies you'll face in the first few levels of the game.

!!!'''Voiced by:''' Jeff Schine

* MoralityChainFromBeyondTheGrave: He ends up playing this role for Jacob, because his hallucination's appearances aren't actually random. [[spoiler: Instead, Max's apparition shows up every time the topic of Jacob's involvement in shipping the alien embryos comes up, with Jacob usually being in denial about his involvement. It is implied that it's actually Jacob's own repressed doubts and consciousness taking Max's shape in Jacob's mind, spurred by the CORE's influence.]]

[[folder:Dani Nakamura]]
!!Dani Nakamura
!!!'''Voiced by:''' Creator/KarenFukuhara
A guerilla fighter opposed to the [[MegaCorp United Jupiter Company]] who finds herself captured and thrown into Black Iron, just like Jacob.

* CruelAndUnusualDeath: Slowly dies via asphyxiation after his suit's visor gets smashed while out on the moon's surface.
