!!!'''Voiced in English by:''' John Hilner [[labelnote:'''Other Languages''']]'''Other Languages''':Valery Storozhik (Russian), Creator/GilbertLevy (French)[[/labelnote]]

* ElementalPowers: Through the use of Plasmids, he can gain these.

[[folder:Dr. Sofia Lamb]]

[[folder:Dr. Gilbert Alexander]]

* ScaryBlackMan: [[spoiler:Once you figure out who Sigma really is.]]

* ScaryBlackMan: [[spoiler:As Sigma.]]

* SoleSurvivor: Alongside [[spoiler:Jack,]] Sigma is the only ''VideoGame/BioShock'' protagonist to survive his game '''and''' to get a happy ending. [[spoiler:Delta, Booker, Comstock]], and [[spoiler:Elizabeth]] all end up dying. Though his is more of a BittersweetEnding than Jack's, having to come to terms with the [[TheLostLenore loss of his wife]] and [[HurtingHero all that happened to him in Rapture]].

* HurtingHero: His state in the wake of all he endured and survived in Rapture, and coming to terms with the loss of his wife.

* ManipulativeBitch: She [[spoiler:engineered her ''own'' jail conviction to gain popular support as a martyr ''and'' place herself in a facility far from Rapture where she could turn the inmates into an army.]] Even ''Fontaine'' is impressed.

%%* FatBastard

* EvenEvilHasStandards: He has done several bad things, but even he finds the idea of being turned into a Big Daddy to be an awful thing to do to someone.

* SanitySlippage: His Audio Diaries show his steady mental decline due to overuse of ADAM, making him bolder and more aggressive towards the leading corporations of Rapture, Ryan especially.
* SelfMadeMan: Idolized Rapture's objectivist ideals until

* FryingPanOfDoom: Her kitchen's frying pan serves as her unique melee weapon.

* AllForNothing: [[He goes so far as to flood the entirety of Dionysus Park, just to cover up his crimes, and sells out Sofia's Daughter to turn her into a Little Sister, and spends years trying to hide it.... only for him to find out Dr. Lamb knew all along, proving his efforts were for nothing.]]

* Foreshadowing: [[spoiler:After The Thinker is temporarily shut off by Wahl, Tenenbaum takes over as MissionControl, hinting that it wasn't actually Porter.]]

* TheCameo: He appears in the single player game's prologue as one of the Lamb supporters who attacks Delta, and is the one who nails Delta with the Hypnotize plasmid that allows Lamb to talk him into shooting himself.

A brilliant mathematician, Porter worked for the allies in London during World War II, losing his wife Pearl to the German bombings. He accepted Andrew Ryan's offer to work in Rapture, building The Thinker, the ultimate processing machine, which he hoped to use to resurrect his dead wife. He was betrayed by his partner Reed Wahl and imprisoned in Persephone, but eventually escaped and teamed up with Dr. Tenenbaum and Subject Sigma to liberate The Thinker and flee Rapture. [[spoiler:Subject Sigma is eventually revealed to be Porter, with the one guiding the player actually being The Thinker.]]

** [[spoiler:His use and, in his own words, blind faith in the Thinker's predictive algorithim. The Thinker, and thus the alorithim, start conspiring against him.]]
** If the player has a good hack build (something the DLC encourages) or just has a few a auto-hack darts up their sleeve, Wahl ''will'' suffer an enormous amount of pain at the hands of his own bots and turrets.
* MadMathematician: Minerva's Den is full of equations scrawled on the walls in chalk, paint and even ''blood'', all presumably Wahl's work in his efforts to find the "predictive equation", an equation he believes can be used to predict the future.
* MustHaveCaffeine: The floor to his office is littered with bottles of Hop-Up Cola, implying he's been using the drink's high amounts of caffeine to keep himself from sleeping on the job.

* VillainousBreakdown: When Sigma approaches closer and closer, and he runs out of Mooks, he gets more and more angry, constantly telling Sigma to turn back and stop. Ending with him [[spoiler:attacking Sigma in a battle he could have told himself would end in his death.]]

The computer created by Reed Wahl and Charles Milton Porter in Minerva's Den. It is a perfect ArtificialIntelligence, maintaining the automated systems of Rapture and running Minerva's Den on its own. Porter, Tenenbaum, and Sigma want it in order to cure ADAM sickness. Unfortunately Wahl controls it, and desires to use it to crack the perfect predictive equation. [[spoiler:It is sentient, and its true allegiance is unknown. It helps Sigma and Tenenbaum, by impersonating Porter while betraying Wahl.]]

* BarrierMaiden: Of ''all'' of Rapture. It's noted that many of the luxeries (automatic doors, mail) and utter necessities (electricity, security) are all handled by The Thinker; if it goes down, everyone goes down with it. Porter even managed to stave off Lamb's Family by threatening to cut off resources to their areas if they don't back off; seeing as there are no Family members in the DLC, it worked.

* WalkingSpoiler: Minus the 'walking' part. Knowing anything more about The Thinker besides that it's a super computer connected to Rapture will give away much of Minerva's Dens plot points.

* GoodIsNotSoft: [[spoiler:She kicks plenty of ass as a Big Sister regardless of your decisions and in one ending where she saves her mother, she admits that she's not doing it out of kindness or love, but [[CruelMercy because she wants to Sofia to live with the knowledge that everything she worked for was for nothing.]] Conversely, in one of the endings where she kills her mother [[PayEvilOntoEvil she states that it's because her mother's sins precluded mercy]].]]

** She constantly decries the self as being the root of all evil yet almost every action she takes is highly selfish. As a therapist she used her therapy sessions to convert vulnerable people to her side rather than helping them cope with her mental issues, treats Eleanor like a tool rather than a person, [[spoiler:kills hundreds of her followers by flooding Siren Alley just to prove how little she cares about Rapture to Subject Delta, smothers Eleanor just to save her skin when Subject Delta reaches her, and attempts to abandon her followers by fleeing in Sinclair’s life boat as a last ditch effort to save herself from Subject Delta and Eleanor.]]

* EvenEvilHasStandards:
** Even she is horrified when she realizes that Subject Delta had his free will restored, and was thus aware of [[FateWorseThanDeath his transformation into a Big Daddy]].

* In one of her audio diaries, as she contemplates what she might have to do to sever Eleanor and Delta's bond, she admits that if she goes through with what she's thinking of doing (non-fatally smothering Eleanor) she wouldn't be able to forgive herself. She even sounds a little choked up at the thought of it.

* {{Hypocrite}}: She preaches collectivism, but she is practically as possessive as Ryan himself. This was true even before she came to power, as she leaves the surface because she believes others have corrupted HER collectivist ideas. She also continually berates Delta for stealing her child away, yet [[spoiler:has been kidnapping children from the surface to make them into Little Sisters]]. Were she less busy trying to murder Subject Delta, she might realize that he perfectly resembles her idea of the "utopian" - working tirelessly, regardless of free will, and willing to die for the sake of another.

* ApologeticAttacker: She asks for Eleanor's forgiveness before she non-fatally smothers her with a pillow to break the pair bond with Delta.

* HopelessSuitor: One of his audio diaries indicate that he has something of a crush on Sofia Lamb- even referring to her as a "Secular Saint"- though he admits that her LoveYouAndEverybody philosophy means that he can't be given preferential treatment.

* MadeOfIron: Subject Delta endures a lot, even by the standards of most Alpha Series. In the cutscenes alone, he's hit by a wall of high-pressure water when a Big Sister shatters a bay window; he's trapped in a room and pelted with gunfire and molotov cocktails until the floorboards under him break, sending him on a three-story fall; the train car he's riding gets torpedoed by Father Wales; Sofia Lamb floods Siren Alley, nearly crushing him to death when a metal door's slammed into him by the resulting water pressure; his link to Eleanor is disrupted [[spoiler:when Sofia half-suffocates her with a pillow]], leaving him on the brink of death; a corridor of demolition charges explode in his face, and he has to [[spoiler:ride to the surface while hanging onto the side of Sinclair's escape pod, being battered and crushed by intense pressure on the way.]]

* AllLovingHero: If Delta saves all the Little Sisters and spares the major [=NPCs=], he'll be interpreted as one by the in-game characters. [[spoiler: To a point where Eleanor in highest Good Ending will pledge to follow his example.]]

* {{Determinator}}: Subject Delta stops at nothing to save Eleanor, not even Sofia Lamb sending an entire city worth of Splicers after him. [[spoiler: Towards the end, even though his bond with Eleanor is broken and he is doomed to die, he still powers through long enough to help her escape to the surface.]]

* HelplessWindowDeath: [[spoiler: In Bad Karma playthroughs, she's drowned by Eleanor while Delta looks on through the windows of the escape pod. For good measure, it's possible to play Delta as being helpless and remorseful in this occasion if you pick the neutral ending.]]

* IHaveNoDaughter: [[spoiler: Right before smothering Eleanor, she bemoans that Eleanor has been learning from Delta's actions instead of her own, rendering her little better than him in Sofia's eyes.]]

* SheepInSheepsClothing: He's the game's Atlas analogue and it's made clear he's done some very shady things in the past... but in the present, his help is totally genuine.[[spoiler: And while you do have to fight him in the end, it's very much against his will and he spends the fight apologizing and encouraging you to kill him.]]

* TheAtoner: [[spoiler: In the Neutral ending, even though she feels she has become a monster, she wonders if she can find redemption like Delta has by choosing to give up his life.]]
* AxCrazy: [[spoiler: Goes into this in the bad endings or even when working to it when she's an ally, butchering through the various splicer types with ''outright glee.'' [[YouBastard And you influenced her into it]].]]

* BadassInDistress: [[spoiler: Turns out she's ''very'' capable of looking after herself. It seems her mother was less afraid of others harming her and more afraid of her daughter simply going her own way.]]

* BerserkButton: [[spoiler: At least for Good Eleanor, harming her father is a good way to earn a harpoon to the gut or an Incinerate! plasmid to the face. Her mother Sofia also learns this the hard way in the Justice ending when she is drowned by Eleanor for condemning her father to death.]]

* BloodKnight: [[spoiler: Fairly low-key if you saved the little sisters, but if you harvested them, she actively enjoys rampaging through the splicers.]]

* CurbStompBattle: [[spoiler: When you summon Eleanor to fight with you in Persephone, she pretty much stomps all over the splicers.]]

* FromNobodyToNightmare: [[spoiler: From a little sister to basically an invincible, teleporting [[BossInMookClothing Big Sister]] with telekinesis. Even more of a case in the Bad ending, in which case she's a BloodKnight that derives joy from both killing things and watching them die, and has both her own genius and Delta's cunning and experience on top of all those powers.]]

* FlashyTeleportation: [[spoiler: As a Big Sister, she appears and disappears with a flash of purple light.]]
* GoodIsNotSoft: [[spoiler: She kicks plenty of ass as a Big Sister regardless of your decisions and in one ending where she saves her mother, she admits that she's not doing it out of kindness or love, but [[CruelMercy because she wants to Sofia to live with the knowledge that everything she worked for was for nothing.]] Conversely, in one of the endings where she kills her mother [[PayEvilOntoEvil she states that it's because her mother's sins precluded mercy]].]]
* HelplessWindowDeath: [[spoiler: In the penultimate level, she's smothered with a pillow by her mother while Delta looks on from behind a window, helplessly thumping on the door. On the upside, she only stays dead for a short while... but on the downside, the smothering was enough to sever her pairbond with Delta.]]

* NeverMyFault: [[spoiler: In the Choice ending, she outright blames Delta for turning her into a monster.]]

* PlayingWithFire: [[spoiler: She can shoot fireballs out of her hands.]]
* PsychicPowers: She can communicate with Delta telepathically. [[spoiler: Later, as a Big Sister and makes use of the Telekinesis plasmid.]]

* UnskilledButStrong: [[spoiler: It is unlikely she's had any formal combat training, instead relying on instinct and what she's observed from Delta to tear apart enemies.]]

* AssholeVictim: [[spoiler: As his acts consist of selling out Johnny Topside and Eleanor to become Big Daddy and Little Sister respectively, as well as killing all witnesses to his wild parties to avoid Ryan and Lamb's scrutiny, it's hard to mourn for him if the player decides to kill him, with the game foregoing the WhatTheHellHero treatment for this occasion and even Eleanor, Lamb and ''Sinclair'' are not sad to see him go. The only reason people might spare him is for the ending and the trophies.]]

* MyGodWhatHaveIDone: [[spoiler: Grace had been assuming that Delta was still a mindless automata. But if Delta spares her, it quickly dawns on her that she was dead wrong and that he is just trying to save Eleanor.]]

* MovingBeyondBereavement: Porter's wife was killed in the London Blitz and he's secretly been unable to move on from his grief ever since then. As such, when he created the Master Computer known as The Thinker, he eventually programmed it to recreate his wife in perfect detail... but when he finally got it right, he realized that it just wasn't her. Instead, he had the Thinker find a way out of Rapture. [[spoiler: After Charles is transformed into Subject Sigma and defeats his treacherous former business partner, the Thinker is eventually able to help him escape to the surface, where he is able to regain his humanity, pay his last respects to his wife and finally move on.]]
