!!Isaac Clarke
[[quoteright:150:http://static.tvtropes.org/pmwiki/pub/images/Isaac_DS2_6582.png]]
[[caption-width-right:150:"Oh yeah. ''Good'' times!"]]
->Played by: Gunner Wright

The star of the series, Isaac Clarke is an engineer with the CEC, dispatched on the USG Kellion to repair the Ishimura. He is also looking for his girlfriend Nicole who is stationed there. He quickly finds that the Ishimura has been overrun with Necromorphs and has to fight through all of them while repairing the ship and rescuing Nicole. By the time of ''VideoGame/DeadSpace2'', his sanity has taken a couple of hits and he has been locked away in an asylum on Titan Station. Unfortunately, another Necromorph attack happens there and Isaac has to once again fight to survive. In ''VideoGame/DeadSpace3'', he travels across the galaxy in hopes of stopping the Necromorph threat permanently.

* ActionSurvivor: Isaac starts the series as a repairman.
* {{Badass}}
** BadassBookworm: He's a very competent engineer who also happens to be a better OneManArmy than the actual [[RedshirtArmy Army]].
** TookALevelInBadass: He was just an engineer, but was forced to take a level at the beginning of the first game.
* BerserkButton: He already had a longstanding mistrust of Unitology, but it turned into outright hatred after the events of the first game.
* CharacterDevelopment: Goes from barely surviving the ''Ishimura'' outbreak to fighting space zombies, government troops and religious fanatics. By the third game he's "The Marker Killer". [[spoiler: After the third game you could probably go ahead and call him The ''Moon Killer'' or something.]]
* CombatPragmatist: Isaac will use just about any advantage offered in melee.
* CoolOldGuy: Isaac is actually in his 40s, according to his official bio. In the first game he was 43, in the second he's about 46, though a lot of that was in stasis so it might not count.
* CrazySane: Tormented by Marker hallucinations pretty much constantly by Dead Space 2 (as well as some honest-to-goodness symptoms of post-traumatic stress disorder [[spoiler: during the Ishimura level]]), he managed to continue to persevere in spite of this, even though his psychological record would draw some rather uneasy glances.
* DeadManWalking: Unless Isaac can cure himself of the nasty things in his brain in the second game, he's doomed to go crazy and die. Struggling to find a way to solve this is the major impetus of the game.
* DeadpanSnarker: Isaac has turned into one of these by the second game, perhaps courtesy of being SuddenlyVoiced. It's understandable, given what he's been through.
--> '''Ellie''': [[GenreSavvy This seems like a really bad idea]].
--> '''Isaac''': Stick around. I'm full of bad ideas.
** When Isaac is keeping the deck of the DrillTank clear, Ellie asks him if he's fine:
--->'''Isaac:''' Oh yeah. Good times!
** Is turned up somewhat for ''VideoGame/{{Dead Space 3}}''.
--->'''Ellie''': Be careful.
--->'''Isaac''': What, you think there's something out there that's trying to eat me?
--->'''Ellie''': Not funny.
--->'''Isaac''': Yeah. I know.
* {{Determinator}}: Isaac Clarke is not going to let a shipful of horrors stop him. [[spoiler:He does his repair jobs alone despite the circumstances, he manages to repeatedly [[DidYouJustPunchOutCthulhu punch out Cthulhu]], refuses to relent when betrayed and left to die, and his HeroicBSOD lasts all of five seconds when he finds out that Nicole's dead.]]
** And in the second game, Isaac doesn't let the fact he's been locked in a mental asylum for the past three years and he's wearing a straightjacket stop him from evading Necromorphs, fashion a plasma cutter and a stasis module out of surgical tools, before suiting up and fighting his way through yet ''another'' outbreak.
* DisappearedDad: It's mentioned that Isaac's father vanished during an extended off-world mission, building ships for the Marine Corp. Due to his work being highly classified, Isaac's attempts to track him down have been thus far mostly futile.
* TheDreaded: Come 3, he's known as "[[RedBaron The Marker Killer]]" by Unitologists, [[spoiler:and even the [[EldritchAbomination Brethern]] [[BiggerBad Moons]] sees Clarke as a big threat enough to the Necromorphs that they personally tries to kill him in 3.]]
* TheEngineer: Isaac's definitely the Combat Engineer variety. This characterization is much better reinforced in the second game than in the first game, where his status as an engineer was more of an InformedAttribute. This time around, his first tools are improvised devises he jury-rigs out of medical equipment, and he occasionally has to do a little rewiring of control panels in the form of a hacking mini-game to bypass inoperative doors. It's taken [[UpToEleven even further]] in ''VideoGame/DeadSpace3'', where Isaac is able to make his own guns.
* TheFaceless: Averted after the first game. Even within that, he can have his face shown in the opening, and has it shown in the closing cutscene as well.
* GadgeteerGenius: In the first game, an InformedAbility on par with [[{{VideoGame/HalfLife}} Dr. Freeman's]] Theoretical Physics degree, but in the second game Isaac's first tool is a Kinesis Module he cobbles together out of parts he rips from a malfunctioning hover-bed. His new plasma cutter is a mash-up of a flashlight and a surgical operating laser, and his new guns in ''VideoGame/DeadSpace3'' will be made from scratch. By him, customized by you.
** The second part of this (the Genius part) is what makes him so effective at combating the Necromorphs [[spoiler: and the Marker]]. Several logs indicate that smart people that come into contact with the Marker are more functional afterwards than people of less intelligence. Isaac takes this to the natural conclusion: [[spoiler: the smartest people are able to defeat the Marker, rather than being consumed by a desire to make it.]]
* GenreSavvy: Becoming this by the time of ''3'', after surviving two Necromorph outbreaks.
* GivingUpOnLogic: In ''Awakened'', the PlayableEpilogue DownloadableContent to ''3'', he notes that he's taken on this approach a ''long'' time ago with respect to the various issues he comes across. It's hard to blame him, all things considered.
* GrayEyes: In regular gameplay and most cutscenes, they're gray. During the infamous EyeScream sequence, they appear blue under direct, bright lighting.
* GuestFighter: Appears as part of Team EA with [[MirrorsEdge Faith]] in [[NBAJam NBA Jam: On Fire Edition.]] Also appears as a skin in ''VideoGame/DantesInferno'', ''[[{{Skate}} Skate 3]]'', and a suit of armor said inspired by him is a DLC bonus in ''VideoGame/DragonAgeII''. Also a costume for Sackboy in ''VideoGame/LittleBigPlanet''.
** Isaac makes his {{fighting game}} debut as a playable character in ''VideoGame/PlaystationAllStarsBattleRoyale''.
* HeroicNeutral: After the events of ''[[VideoGame/DeadSpace2 Dead Space 2]]'', his response to Norton's request for help is a resounding no. [[TheCallKnowsWhereYouLive But then he learns the Ellie is missing, and Unitologists try to kill him.]]
* HeroicMime[=/=]TheQuietOne: In the first game, with nothing but VoiceGrunting and screams. Interestingly, he does have things to say if you look at his notes on the objectives. He's intelligent, and not gullible or naive. He is, however, ''scared out of his mind''.The grunts and screams are somewhat on the extreme side, almost making him a ScreamingWarrior. Entirely justified in that, when he's stomping the crap out of the monsters he comes across, he's ''scared to death'', and likely is trying to resolve some of that fear any way he can.
** SuddenlyVoiced: In ''VideoGame/DeadSpace2''. As the game drops the "Alone in a HauntedHouse with ApocalypticLog" storytelling, it makes sense he'd speak to other characters about his... problem. Though some find his new voice a bit less... [[RatedMforManly imposing... than some of his grunts in the original game would suggest]]. Maybe it's just the SanitySlippage.
** He also speaks at the end of the first game, though hard to miss. On the final chapter a muffled and disgruntled "Come on!" can be heard when Isaac is banging on the door for it to open.
* [[spoiler:HeroicSacrifice: Twice. In 2, he willingly sacrifices himself to stop the Golden Marker's Convergence, but Ellie [[BigDamnHeroes will have none of that]]. Again in the end of 3 to shut down the Marker signal from the Tau Volantis Brother Moon... [[ShootTheShaggyDog but it doesn't work]]. Luckily, [[LegallyDead he's still not dead]].]]
* HeroicWillpower: Isaac takes debilitating hallucinations quite well. At least one other character mentions that out of everyone exposed to the Marker, he was by far the most stable. In the end, [[spoiler: this is what saves him. In fact, his BattleInTheCenterOfTheMind seems to even destroy the giant Marker! No surprise he looks totally drained afterwards]].
* InformedAbility: Averted more and more as time goes on: Isaac must physically rewire control panels in order to activate different machines or devices, which certainly requires more engineering know-how than simply pushing a button on a screen. He can also make guns as of ''VideoGame/DeadSpace3'', which definitely requires a lot of know-how. Justified by the developers as a way to highlight and emphasize Isaac still being an engineer rather than a SpaceMarine.
* InkSuitActor: Averted at first, as he had no actor to begin with in the [[VideoGame/DeadSpace original]]. But then played straight in the sequels, with him SuddenlyVoiced, which called for a redesign of his appearance to fit Wright's.
* {{Irony}}: [[spoiler: Since Nicole's body is [[NeverFoundTheBody never found]] and she killed herself in a manner that would leave herself open to infection, it's possible that she might have been one of the countless Necromorphs killed by Isaac, whilst he searched through the ''Ishimura'' looking for her.]]
* [[spoiler: ItsAllMyFault: Sees Nicole's death as this, due to pushing her to take the job on the ''Ishimura'' in the first place.]]
* KleptomaniacHero: Isaac steals more or less everything he comes across. Mostly justified, since the previous owners are all dead. Everything he doesn't steal is readily purchased from your local Ishimura Store terminal. With looted money. That he acquired by selling other stolen stuff.
* MadeOfIron: Let's see, he has survived the outbreak on the Ishimura, the destruction of Aegis VII, the destruction of the Sprawl, has defeated several massive creatures, and recently [[spoiler:''killed a moon''. Did the destruction of the moon kill him? Nope. He survives that too! And in every single one of these instances, he constantly gets injured or attacked, and yet he keep on trekking. This man refuses to die.]]
--> '''Danik''': "Isaac, is that you? You are unbelievably hard to kill. Are you aware of that?"
* MeaningfulName[=/=]NamedAfterSomebodyFamous: A meta version. Isaac ([[Creator/IsaacAsimov Asimov]]) ([[Creator/ArthurCClarke Arthur C.]]) Clarke - which of course was mocked by ''WebAnimation/ZeroPunctuation''.
* MindRape: Repeatedly suffers these during ''VideoGame/DeadSpace2'' as a result of what happened in 1.
* MysteriousPast: Very little is known of Isaac's past. Some logs in the first game indicate strong familiarity with the crew of the ''Ishimura'' such as Gabe Weller, implying that in addition to Nicole, he had several friends serving onboard at the time. Some have even [[WildMassGuessing theorised]] that Isaac himself may even have served on the ship previously or at least repaired it a few times and that was how he found out about the job opportunity for Nicole.
* ParentalNeglect: You will find in Isaac's bio that he was not priority number one for his parents.
** Somewhat justified in the case of his father, who vanished during an extended mission off-world whilst building ships for the Marine Corp. That said, his father ''did'' make sure to spend the first four years of Isaac's life on Earth with the family. His mother on the other hand, threw herself into Unitology out of loneliness and later depression when her husband disappeared. Her fanaticism lead her to blow most of their family's wealth on getting herself risen to the rank of Vested within the Church, preventing Isaac from attending a prominent engineering college in the process and driving a permanent wedge between them.
* PermaStubble
** Turns into a BeardOfSorrow in ''3''.
* PrecisionFStrike: At the end of ''VideoGame/DeadSpace2'':
-->[[spoiler: "Fuck you! And fuck your Marker!"]]
* RightManInTheWrongPlace: In ''Dead Space 1'' he was just an engineer that only volunteered to go to the Ishimura in order to find his girlfriend, only to get way more than he bargained for with Necromorphs, yet he still managed to eliminate the Necromorph scourge on Aegis VII. In ''Dead Space 2'' he's yet again caught in the middle of another Necromorph infestation, and manage to stop a Convergence event from happening.
* ReluctantHero: In ''3'' due to his experiences. This shakes off when he's told to help Ellie.
* SanitySlippage: Isaac suffers from hallucinations because some of the Red Marker's influence still lingers.
** He's cured of the hallucinations at the end of ''2'', although there are signs he suffers from lingering mental trauma. [[spoiler: He relapses into hallucinations in the ''Awakened'' DLC, mostly because there's an entire EldritchAbomination race trying it on him and Carver.]]
* SecondLove: Subverted. Isaac and Ellie initially got into a relationship after the events of the second game, but broke up by the beginning of the third. [[spoiler: Double subverted by the end of the game, when Isaac and Ellie share one final kiss before he takes on the Brother Moon.]]
* ShellShockedVeteran: The events on the Ishimura have quite an impact on him. The Sprawl does as well in terms of both trust and horror.
* SurvivorsGuilt: After the events of the first game. [[spoiler: Also because Isaac was the one to push Nicole to take the job on the ''Ishimura'' in the first place, thus indirectly making him responsible for her death]].
* TenMinuteRetirement: Had slipped into a life of seclusion after the events of ''2'', tired of hunting down Markers. Fortunately for the galaxy, TheCallKnowsWhereYouLive and pulls him out of his brief retirement.
* UnwittingPawn: [[spoiler:To [[VideoGame/DeadSpace Kendra]], the [[VideoGame/DeadSpace2 Golden Marker]], and eventually ''[[VideoGame/DeadSpace3 the Brother Moons]]''.]]
[[/folder]]

[[folder: USG Kellion Crew]]
!!Zach Hammond
->Played by: PeterMensah

CO of the USG Kellion that accompanies Isaac and Kendra to the Ishimura.

* {{Badass}}
** BadassNormal: Unlike Isaac who has a powersuit and powerful tools improvised as anti-Necromorph weapons, Hammond only has the basic uniform and a Pulse Rifle that's not as effective. He still manages to survive completly on his own wandering the Ishimura and take down a presumably large number of Necromorphs himself.
* BaldBlackLeaderGuy
* BaldOfAwesome
* BrownEyes
* CharacterDevelopment: Goes from being dead set on completing the mission to simply wanting to get off the Ishimura.
* [[spoiler: CruelAndUnusualDeath: The Brute who attacks Hammond first pulls off his leg slowly, than pounds him repeatedly with it's giantic armored limbs and finally smashes him through thick safety glass.]]
* {{Jerkass}}: Starts the game all business and being rather demanding.
** JerkWithAHeartOfGold: However, he does show concern about Isaac's search for Nicole, and eventually abandons the repair mission in order to get his surviving crew off.
* MissionControl: Isaac is ordered around by a lot of people, but he is the main one.
* [[spoiler: RedHerring]]: You would think throughout the first part of the game that [[spoiler: he has something to do with the Marker and Unitologists]]. You'd [[spoiler: be wrong.]]
* VoiceWithAnInternetConnection: Along with Kendra.

!!Kendra Daniels
->Played by: Tonantzin Carmelo

Computer specialist of the USG Kellion. She does not get along with the rest of the crew.

* [[spoiler:BigBad: Of 1, being sent to cover up the Aegis VII incident.]]
* [[spoiler: BitchInSheepsClothing]]
* CurtainsMatchTheWindow
* [[spoiler: KarmicDeath]]: [[spoiler:After stealing the Marker that was keeping an EldritchAbomination imprisoned, she gets killed by said newly freed abomination.]]
* [[spoiler: TheMole]]: [[spoiler: She's actually working for the government and put on the rescue mission by her higher-ups.]]
* [[spoiler: ManipulativeBitch]]: [[spoiler: Plays Isaac and Hammond against each other and acts friendly towards Isaac so she can get him to do most of the work.]]
* [[OnlySaneMan Only Sane Woman]]: She frequently argues with Hammond to abandon the mission and rightly stating that he's out of his league. [[spoiler: Of course, this later turns out to be an act.]]
* VoiceWithAnInternetConnection

!!Corp. Chen

The pilot who lands the Kellion on the Ishimura.

* MauveShirt
* [[spoiler: WeHardlyKnewYe]]

!!Corp. Johnston

[[folder: USG Ishimura Crew]]
!!Capt. Benjamin Mathius
->Played by: J.G. Hertzler (''VideoGame/DeadSpace''), JimCummings (''WesternAnimation/DeadSpaceDownfall'')

The original Captain of the USG Ishimura. He is secretly a devout Unitologist.

* AuthorityEqualsAsskicking: For no particular reason, the good Captain is the first [[EliteMooks enhanced]] Necromorph you face.
* TheCaptain
* EyeScream: In the game we only get to see it via audio log. In ''WesternAnimation/DeadSpaceDownfall'' it's shown in all its squickly detail onscreen.
* KnightTemplar
* SanitySlippage

!!Dr. Terrence Kyne
->Played by: KeithSzarabajka

Chief Science Officer of the Ishimura and devout Unitologist. Fearing what would happen if the Necromorph outbreak spreads, he sabotaged the ship, until visions of his deceased wife shows him how to stop the outbreak.

* TheAtoner: All he wants to do is make things right after helping cause the Necromorph outbreak.
* ActionSurvivor
* {{Badass}}: By virtue of surviving on the Ishimura for so long.
** TookALevelInBadass
** BadassBookworm
* {{Cloudcuckoolander}}
* DeadPersonConversation: Chats with his dead wife.
* FailureKnight
* [[MadScientist Reluctant Mad Scientist]]
* OnlySaneMan: Ironically, when it comes to the Marker.
* SanitySlippage: After the Marker is brought on board the ship, he starts seeing and talking to his dead wife.
* TheSmartGuy

!!Dr. Challus Mercer
->Played by: Navid Negahban

Another MadScientist and Unitologist on the Ishimura. Audio logs Isaac finds detail how the Necromorphs drove his already unstable mind into full blown AxCrazy. When Isaac finds him Mercer has been experimenting on humans and Necromorphs, the results of which he unleashes on Isaac.

* AxCrazy
* BigBad
** [[spoiler: DiscOneFinalBoss]]
* BeardOfEvil
* TheDragon: Has one in the form of the Hunter. [[spoiler: Is acting as one to the Hive Mind]].
* EvilutionaryBiologist
* TheFundamentalist
* KnightTemplar
* MadDoctor[=/=]MadScientist: Creates stronger Necromorphs by experimenting on human beings.
* TheManBehindTheMonsters: While not leading the Necromorphs directly, [[spoiler:the true leader is the Hive Mind]], he is helping to advance the Necromorph infection and create new, more powerful types of Necromorphs.
* MeaningfulName: Mercer is an old term for a dealer of textiles. Seems he's [[IncrediblyLamePun a man of the cloth]]. Another interpretation: Methicillin-resistant Staphylococcus aureus is a type of bacterium responsible for numerous difficult-to-treat or outright incurable ailments in human beings. It's abbreviated MRSA, and the abbreviation is often pronounced "Mer-sah" or Mercer.
* OmnicidalManiac: Mercer's master plan, such as it is, is to use the Ishimura to transport a group of Necromorphs to Earth, where he'll unleash them to turn the entire planet into Necromorphs. This plan's not particularly realistic given the current condition of the Ishimura, and he eventually forgets about it entirely and feeds himself to an Infector.
* [[spoiler:OneWingedAngel]]: After Isaac kills [[spoiler:the Hunter]], Mercer [[spoiler:lets an Infector turn him into a Necromorph. His transformation isn't anything special though, as he just becomes another Enhanced Slasher. The process can even be averted if the player is fast enough to kill the Infector before Mercer transforms]].
* SanitySlippage
* WorthyOpponent: He respects Isaac's ability to survive and constantly compliments his efforts, even if he does believe Isaac's only fighting the inevitable.

!!Nicole Brennan
->Played by: Iyari Limon & Tanya Clarke

Isaac's long-term girlfriend, a medical officer stationed aboard the Ishimura at Isaac's suggestion. Nicole didn't suffer any negative effects from the Necromorphs, and managed to send out a message to Isaac saying that the place is falling apart (though she doesn't say what the problem is), alerting Isaac that something is wrong. Isaac spends most of the game looking for her. Nicole also makes cameo appearances in ''Downfall'' and ''Extraction''.

* [[spoiler: BetterToDieThanBeKilled]]: [[spoiler: Her reason for committing suicide, she preferred to die by her own hand rather than be ripped apart by Necromorphs]].
* [[spoiler: DeadAllAlong]]
* DistressedDamsel
* [[spoiler: DrivenToSuicide]]
* HairOfGoldHeartOfGold
* HospitalHottie
* TheLostLenore
* TheOtherDarrin
* [[spoiler: NeverFoundTheBody: Isaac at one point encounters room she's later revealed to have died in, but her body is no longer there. This suggests that she did indeed end up become one of the Necromorphs onboard the ''Ishimura'' and ironically might have been one of the countless number killed by Isaac as he ventured through the ship searching for her. The Nicole hallucination pointedly guilt-trips Isaac about this in ''Dead Space 2''.]]
* ProperLady: She is very kind, sweet, compassionate, and calm.

!!Jacob Temple

Acting Chief Engineer of the USG Ishimura after most of the crew is dead. His story is chronicled through various logs Isaac finds, where he attempts to repair the Ishimura and find his girlfriend, Dr. Elizabeth Cross.

* {{Badass}}
* {{Determinator}}
* HeroOfAnotherStory: His journey through the Ishimura mirrors Isaac's, with him trying to repair the ship and finding his girlfriend.
* [[spoiler: ShootTheShaggyDog]]

!!Gabe Weller
->Played by: Ramon Tikaram

A security officer on the Ishimura and the second player character in ''Extraction''. He is sent down to Aegis VII to retrieve the bodies of the mass suicide and happens to meet up with his old friend, Nathan [=McNeill=]. The bodies are found to be gone, and he and Nathan have to escape Aegis VII as they soon discover what the bodies have transformed into.

Weller is the main character in ''Severed'', re-appearing alongside Lexine as the two try to get off the Sprawl.

* [[spoiler:AnArmAndALeg: Loses a leg from a grenade in ''Severed''.]]
* BadassBookworm: Although he's a security guard, rather than an engineer, he's just as capable of rewiring panels as Isaac.
* [[spoiler: HeroicSacrifice: At the end of ''Severed'', he is badly injured and has to sacrifice himself to save Lexine.]]
* JerkWithAHeartOfGold
* TheMeanBrit
* LateToTheTragedy: His chapter one in ''Severed'' starts off just as the Necromorphs are attacking the hospital, but by the time he gets there, Isaac is long gone and the place is in even worse condition.
* [[spoiler: RedHerring: One is naturally inclined to assume he's the one who becomes the necromorph at the end of ''Extraction'', since the shadow of the slasher depicts it with two human arms and, well, [=McNeil=] only has the one.]]
* WithThisHerring: Averted, unlike Isaac, he's pretty heavily armed from the get-go.
* VitriolicBestBuds: With Nathan.

!!Karen Howell
->Played by: Archie Panjabi

A doctor and botanist who managed to survive on the Ishimura by herself for a while before the rest of the group meets up with her.

* ActionGirl: She fought off hordes of Necromorphs and even killed a Brute.
* AnkleDrag: Karen Howell is dragged away by a tentacle, [[spoiler: she doesn't make because Warren abandoned her when she called him out for seeding Unitologists in the Isimura's ranks.]]
* DeadlyDoctor: She starts out with a Ripper. One can only wonder why she was carrying it.
* TheLargestDemocracy: Where Karen Howell probably comes from.
* LowerDeckEpisode: She has one level starring her. She kills a brute protecting Lexine, but she [[spoiler: dies when she calls Warren out for seeding Unitologists into every corner of the ship. Immediately afterwards she is attacked by a tentacle and left to die by Warren while he yells about his "god" having different plans. This leaves the player in [[CaptainObvious serious doubt of his character.]]]]

!!Alissa Vincent

The head of security PCSI security on the Ishimura and the protagonist of ''WesternAnimation/DeadSpaceDownfall''.

* ActionGirl
* {{Badass}}

!!Sam Caldwell

An engineer stationed on Aegis VII and Lexine Murdoch's boyfriend. What was supposed to be a routine planet crack changed due to the discovery of a mysterious red artifact. He and his team are sent to extract what everyone is now calling "The Marker"...

* DecoyProtagonist

* [[spoiler: ThroughTheEyesOfMadness: Kills his entire crew, believing them to be monsters.]]

!!Nathan [=McNeill=]
->Played by: Joseph May

A detective stationed on Aegis VII and the player character whose point of view is shown through most of the game. He was investigating the bizarre rash of murders and insanity since the extraction of the Marker, until he meets up with his old friend Gabe Weller from the USG Ishimura. He soon finds himself trapped on a madness-ravaged Aegis VII, along with an alien threat known as the Necromorphs.

* [[spoiler:BrokeYourArmPunchingOutCthulhu: The Spider impales his arm with a spike before leaving, ultimately causing his infection and death.]]
* NiceGuy
* [[spoiler:TheHeroDies: Was the one that became a necromorph at the end of Extraction, forcing Lexine to kill him.]]
* PrivateDetective: In origin.
* VitriolicBestBuds: With Gabe.

!!Lexine Murdoch[[spoiler:-Weller]]
->Played by: Laura Pyper

A surveyor of Aegis VII and girlfriend of Sam Caldwell. As the Aegis VII colonists go mad, she tries to find sanctuary in the security office, but joins Nathan and Gabe as they all try to escape from the Necromorph attack.

Lexine reappears in ''Dead Space 2: Severed'', once again trying to escape from Necromorphs.

* ActionGirl: She protected Gabe and found painkillers, off-screen.
* DamselInDistress: She's stuck in the hospital during the second Necromorph attack. [[spoiler: She's also one of the Key Subjects Tiedemann marked for Termination alongside Isaac, and the Church of Unitology wants her as well.]]
* TheChick: Most of the time, she has to be protected by Nathan and Weller, [[spoiler:but you do see her use a gun and defend herself later on.]]
* DoomMagnet: [[spoiler:Everyone close to her winds up dead.]]
* [[spoiler:TheImmune: She is immune to Red Marker influence like Michael Altman, and imparts resistance to it to those who remain in close proximity.]]
* [[spoiler:MacGuffinGirl]]: In ''Extraction'', [[spoiler:she somehow has the ability to nullify the Marker hallucinations which is why the Church of Unitology is after her]]. In ''Severed'' [[spoiler: She was one of the subjects in Tiedemann's project, likely because of her ability to cancel out Marker-induced hallucinations. It's revealed that she's pregnant, and her and Gabe's child was also of interest to the government]].
* ZettaiRyouiki: She wears this on top of normal pants.

!!Warren Eckhardt
->Played by: Jon Cartwright

Executive Director of Colonial Mining Affairs for the Concordance Extraction Corporation. He survives the crash that wipes out the shuttles, and relies on Nathan, Gabe, and Lexine for protection, as he possesses the last working shuttle off the planet.

* [[spoiler:InTheBack: By a Slasher after shooting Weller.]]
** [[spoiler:KarmicDeath: Caused by the subject of his own religion.]]
* TheLoad: He doesn't really do anything after giving them the shuttle.
* [[spoiler:TheMole: For the Unitologists who want to take Lexine.]]

!!Abraham Neumann

A P-Sec officer and the protagonist of a comic prequel to the game.

* NobleBigotWithABadge: Has a very dim view of Unitology, based on his ex-wife's devotion to it. He's not hesitant about spouting off his distrust of it, even around his Unitologist partner. Despite this, he is generally trying to help people. Given what happens to many Unitologists later, it isn't completely unjustified.
* OnlySaneMan: Not quite, but he figured the Marker was bad news as soon as it was dug up.
* WhatHappenedToTheMouse: [[spoiler: After leaving a final recording, he wanders off into the Necromorph-filled hallways of the colony, likely killed by them. Isaac can find his recording in-game.]]
[[/folder]]

[[folder: USG O'Bannon Crew]]
!!Nolan Stross
->Played by: Curt Cornelius

A scientist that experimented on [[spoiler: part of]] a Marker in ''WesternAnimation/DeadSpaceAftermath''. Stross went insane and was locked up on the Sprawl after he killed his wife and daughter (whether he was hallucinating or if they had turned into Necromorphs is unknown). In ''VideoGame/DeadSpace2'' Stross knows Isaac since they both had information about the Marker, and insists that he knows how to destroy it, but his incoherent ramblings make him hard to understand.

* AssholeVictim: His hubris is directly responsible for everything that happens on the O'Bannon in ''[[WesternAnimation/DeadSpaceAftermath Aftermath]]''. Even before he came under the Marker Shard's influence and brutally murdered his wife and infant child, he was still an arrogant dick, who was cheating on his wife, planned on leaving her, and thought too highly of himself to consider that maybe, just ''maybe'' he shouldn't be playing with the Red Marker fragment. When hell broke loose, he panicked completely, leading directly to a lot of people's deaths.
* BuriedAlive: Stross' greatest fear manifested by the interrogation chair.
* CanonImmigrant: He appeared in ''WesternAnimation/DeadSpaceAftermath'' before ''VideoGame/DeadSpace2''.
* {{Foreshadowing}}: Stross leaks it pretty much every time he opens his mouth.
* [[spoiler:FaceHeelTurn]]
* HeroicBSOD: He killed his wife and kid while hallucinating. The guilt eventually leads to his death.
* TheLoad: Stross is a completely useless liability. He gives you a few hints on where to find the Marker, claiming he knows how to destroy it, but after that he degenerates rapidly into a MadnessMantra and has nothing to contribute. [[spoiler: Once he becomes violent, Isaac struggles with him and kills him. Turns out, his help was unnecessary, anyway]].
** To the point that the developers put an audiolog [[spoiler: on his body, in the extremely likely event that the player would want to abuse his corpse.]]
** He was also this in ''Aftermath'', culminating with him [[spoiler:Hesitating to throw the Marker shard inside the ship's engines to destroy it, while the other survivors were fighting for their lives against the Necromorphs.]]
* MadnessMantra: The steps.
* NeverMyFault: His FatalFlaw. As ''WesternAnimation/DeadSpaceAftermath'' showed, he was responsible for the death of several people after breaking a seal on a door which let a necromorph slaughter a crew of workers. Driven insane by it, he brutally murders his wife, Alexis, and their son, by his own hands. By refusing to accept responsibility for his actions, the Marker slowly drives him crazy in ''2'', [[spoiler:to the point he [[FaceHeelTurn starts attacking Isaac and Ellie]], forcing Isaac to kill him in self-defense]].
* ShadowArchetype: To Isaac. Isaac and Stross were both brought to the same colony and suffer from similar delusions under the Marker's influence. However, Isaac accepts his girlfriend's death and stays sane, while Stross let's his guilt consume him.
* SanitySlippage: Starts out fairly coherent and helpful, and gradually degenerates through the course of the game as the Marker eats away at his mind.
* ThroughTheEyesOfMadness: He kills his wife and kid because he saw them as a slasher and lurker respectively.

[[folder: Personnel, Residents and Crew of The Sprawl]]

!!Vandal, aka [[spoiler:Karrie Norton]]
->Played by: [[spoiler: Anna Vocino]]

A newly converted Unitologist who takes on a secret mission to sabotage the Sprawl, believing it is some sort of protest against [=EarthGov=], but is actually a way for the Necromorphs to reach the Sprawl. After a MyGodWhatHaveIDone moment, Vandal starts working with Tiedmann to keep the Necromorphs from reaching the residential part of the Sprawl. The protagonist of the ''Dead Space'' [=iOS=] game.

* [[spoiler: ActionGirl]]
* TheAtoner: After causing the Necromorph outbreak on the Sprawl, Vandal works to keep it contained.
* ChainsawGood: In contrast to Isaac, who was limited to punching Necromorphs, Vandal starts out with a one-handed plasma saw (essentially a chainsaw with an energy blade) for melee attacks.
* OneSteveLimit: [[spoiler: There's nothing to suggest that Karrie Norton is related to Robert Norton.]]
* OnlyKnownByTheirNickname: Vandal is the codename given to Vandal by Tyler Redikov, Vandal's handler.
* [[spoiler: SamusIsAGirl: The shocking twist behind Vandal's true identity in the ending proves that this trope is not dead yet.]]
* SanitySlippage: Vandal struggles with this throughout the game.

!!Ellie Langford
->Played by: Sonita Henry

A Class 4 heavy equipment pilot working on the Sprawl when all Hell breaks loose. She and a few of her friends lasted for a while, but by the time Isaac finds her she is the only one left. She is at first reluctant to trust Isaac, but goes along with his plan to destroy the new Marker and stop the Necromorphs.

* ActionGirl: A CEC Class Four Heavy Equipment pilot. She kicks major ass and calls Isaac a nerd.
** BadAssBookworm: When you first meet her, she's fighting off Necromorphs. No big deal, right? Except she's ''knows'' they can rip her apart, and is safely taking them apart from behind a security fence. No one else thought to do this in the chaos of the outbreak.
** FauxActionGirl: In Dead Space 3. Granted, she is still a helpful asset to Isaac and barely avoids {{Chickification}} by not being a DistressedDamsel for the most part. However, she hardly does anything to defend herself onscreen despite having to be shown as an ActionGirl in the previous game.
* ActionSurvivor: One of very few characters to survive a ''Dead Space'' game. [[spoiler:And only one of three people who has survived two outbreaks.]]
* AmbiguouslyBrown: Ellie's apparently modeled after her voice actress Sonita Henry, who's mixed-race.
* {{Badass}}: In Dead Space 2, considering how well she survives, even when defending people by herself.
* DefrostingIceQueen
* {{Determinator}}: After [[spoiler:Stross gouges out her eye]] her RIG shows she only has about 15% health left, yet she struggles on and continues to kick ass unabated.
* ElectronicEye: Implied in ''3'', having two eyes of different colors and no coordination problems. [[spoiler:It was a replacement after all.]]
* [[spoiler:EyeScream]]: [[spoiler:Courtesy of Stross with a screwdriver.]]
** [[spoiler:EyepatchOfPower: For the rest of the game.]]
* GirlishPigtails: In ''2'', despite a severe girlishness deficiency otherwise.
* MajorInjuryUnderreaction: [[spoiler:Her eye is gouged out. Her response to this is to insist Isaac owes her a new one while kicking the assailant's ass.]]
* SecondLove: Zig-zagged. She and Isaac became a couple after the events of "2", but she broke up with him by the start of "3", ultimately starting a relationship with Captain Norton. [[spoiler: After Norton's betrayal and death, their love blossoms again.]]
* StiffUpperLip: Given her mixed heritage and accent, she's British. She pretty mellow for losing an eye.
* SurvivorGuilt: She was the only member of her CEC crew who escaped the CEC facility on the Sprawl and displays some shades of survivor's guilt. She's reluctant to team with Isaac at first, and [[spoiler:is not happy when Isaac forces her to leave on a shuttle while he prepares to go off on a HeroicSacrifice. In 3, she does it ''again'']].
* [[spoiler: TookALevelInJerkass: To a minor degree in ''3'', as she's revealed to have broken up with Isaac because he refused to face his demons in lieu of simply running from his past. While her frustration is somewhat understandable and it would put pressure on any relationship; considering she knows Isaac's survived ''two'' Necromorph outbreaks, spent three years being tortured in a hospital for information and been subjected to a ton of MindRape by the Markers, you'd think she'd understand ''why'' he's so [[ShellShockedVeteran shell-shocked]] and reticent to deal with it?]]


!!Hans Tiedemann
->Played by: Lester Purry

The director of Titan Station, he was the one running the project that extracted the knowledge in building Markers out of Isaac's head and is partially responsible for the new Necromorph outbreak. He spends most of the game trying to stop Isaac and Ellie from getting to the Marker.

* BaldBlackLeaderGuy
* BoomHeadshot: Possibly his death.
** Combined with ImpaledWithExtremePrejudice right before the above.
* {{Determinator}}: It doesn't matter that the station is almost destroyed, all his men are dead, monsters are everywhere and he himself has horrific injures - while he is alive, Tiedemann ''will not'' let you reach the Marker.[[spoiler: And he's justified in trying to do it too]].
* [[spoiler:FacialHorror: Towards the end of the game, he is caught in an explosion, resulting in him losing a lot of the flesh on his face, as well as his entire nose. And he's ''still alive''. Ouch.]]
* ForScience: Tiedemann's excuse. Partly justified as the game suggests that ''all'' attempts to replicate the Marker (including the serious scientific ones) are in fact manifestations of the Marker's influence on the human mind.
* IDidWhatIHadToDo: Whilst he does inhibit Isaac, he does occasionally show empathy for him, and even states that, under different circumstances, he'd find his persistence admirable. [[spoiler: An audio log later in the game also reveals that, despite the demands of his superiors, Tiedemann made sure that a decent amount of people could escape.]]
* KnightTemplar
* PetTheDog: Near the end of the game, you find logs that reveal that Tiedemann's order to evacuate Titan Station, given near the start of the game, was directly against the wishes of his superiors. [[spoiler: Evacuate everyone except the people who came in contact with the Marker, who are to be killed by Sprawl Security, that is... which, considering that the Marker's architects are required for its activation, has its justifications too.]]
** In ''Dead Space Mobile'', Tiedemann is quite reasonable towards Vandal and is rather quick to be willing to work with her after she explains she's not his enemy. This is quite a contrast to his no-compromise, kill-at-all-cost attitude towards Isaac.
* TheDevTeamThinksOfEverything: [[spoiler: You can fry him with the javelin gun's secondary fire, rather than an aiming QTE.]]
* VillainousBreakdown: The closer Isaac gets to the Marker in the second game, the more unhinged he becomes. Tiedemann goes from being polite and respectful to screaming lunatic. This also shows up in the ways he tries to stop Isaac's progress. At first, he removes Isaac and Ellie's security protocols so they can't access the systems. By the end, he's cut a tram's tracks in half with a solar beam, and sent two hundred armed guards to kill Isaac personally.
* WellIntentionedExtremist: [[spoiler: Yes, he tries to kill you multiple times, and yes, he's the one who left you to rot in an asylum for three years, and yes, he's a dick, but it's implied he had ultimately good intentions and was following orders. Also, he refused to let the civilians of the Sprawl under his care die and issued an evacuation against direct orders of his superiors]].
* WorthyOpponent: Considers Isaac to be one in ''2'', though this begins to drop off as Tiedemann undergoes a VillainousBreakdown.

!!Nicole Brennan Hallucination[[spoiler:/The Golden Marker (12B)]]
->Played by:Tanya Clarke

A hallucination Isaac experiences repeatedly during the game. In contrast to the real Nicole, this Nicole is mean-spirited and spiteful, alternating between belittling Isaac and flat out yelling at him.

* [[spoiler: AssimilationPlot: Her/its ultimate goal, if her/its BossBanter is anything to go by.]]
* [[spoiler: BigBad]]
* [[spoiler: BlueAndOrangeMorality]]
* DeadPersonImpersonation
* EldritchAbomination: Implied.
* LargeHam
** [[spoiler:EvilIsHammy]]
* PsychicAssistedSuicide: Capable of inflicting this on Isaac if he doesn't fight off her influence. Including having him cause a NeckSnap to ''himself''.

!!Daina [=LeGuin=]
->Played by: Tahyna Tozzi

The first person to contact Isaac once he breaks out of the asylum. She says she knows how to make the hallucinations stop, and spends the first third of the game directing Isaac to her.

* {{Expy}}: To Kendra. Both were your VoiceWithAnInternetConnection, female, and well-endowed. [[spoiler:And they both betray you, only to be killed shortly after.]] Lampshaded by Isaac when they meet in person.
-->'''Isaac:''' [[spoiler: You're a Unitologist? Oh, wait. Of ''course'' you're a Unitologist.]]
* [[spoiler: FalseFriend: She pretends to want to help cure you. It's a damnable lie.]]
* [[spoiler: KarmicDeath: Dies within seconds of revealing her insane plan to have you build markers.]]
* [[spoiler: MissionControlIsOffItsMeds: Given what she does, she's this. She's a Unitlogist.]]
* [[spoiler: TreacherousAdvisor: Betrays you BEFORE she even bothers to look at you.]]
* VoiceWithAnInternetConnection

!!Dr. Foster Edgars
->Played by: Rick Cramer

A doctor who experimented on Isaac and Stross. When Isaac runs into him, he cuts Isaac out of his straitjacket, apologizes for what he did, and slits his own throat.

* DrJerk
* DrivenToSuicide
** SlashedThroat
* MyGodWhatHaveIDone
* PetTheDog: His last words are an apology.
* SanitySlippage

!!Col. Victor Bartlett

Appearing only in ''Severed'', Bartlett is Weller's superior officer. Despite the Necromorph outbreak, he directs Weller around the Sprawl and tries to help him reach Lexine.

* EyeScream: Gets his eyes torn out by the Oracles. [[spoiler: Doesn't stop him from lethally wounding Gabe though.]]
* [[spoiler: FaceHeelTurn: Initially it seems like he's helping Gabe, however, he sics a gunship on Weller and tries to kill Lexine.]]
* [[spoiler: IHaveYourWife: Sort of, he calls you at multiple times in chapter 2 to remind you how he's tracking her down and going to kill her.]]
* [[spoiler: JustFollowingOrders: He's ordered to kill Lexine.]]
[[/folder]]

[[folder:Sovereign Colonies Armed Forces]]
The military attachment present for the Sovereign Colonies expedition to Tau Volantis, 200 years prior to the events of Dead Space 3. They're obviously all dead by the time Isaac visits, but the specifics of how they died are quite the mystery.

'''In general'''
* BrainwashedAndCrazy: Not all of them, but the 163rd division, the 'Reapers,' are apparently psychologically conditioned to accept orders. In there barracks, they have their own version of [[spoiler: the Liquidation order]], which is instead a series of repeated instructions plus many subliminal images.
* KillEmAll: [[spoiler: Once they received the Liquidation order from Command, they scuttled all vehicles, purged all data, and killed absolutely everyone]].
* LeaveNoWitnesses: [[spoiler: Part of the Liquidation order]].
* NewMeat: There was a civil war on Earth occurring during the same time period of the excavation, so Sovereign Colonies Command mostly sent those who they judged weren't vital to the war effort, plus a few veterans to keep them in line. Many of the more experienced soldiers lambasted that, "half of these guys don't know how to hold a gun, and the other half run for the hills when they hear one go off."
* [[PosthumousCharacter Posthumous Characters]]: Everyone, considering their time on Tau Volantis was 200 years before the series proper.
* UndyingLoyalty: Granted, not 100% loyalty, but there are enough fanatically loyal soldiers present that a [[spoiler: [[KillEmAll Liquidation order]] is met with near-universal acceptance in the military attachment. One text log describes a soldier retrieving a body bag, sharing a last smoke and speech with the author, sitting down inside and then calmly offing himself]].

!!Maj. Gen. Spencer Mahad
->Played by: KeithSzarabajka

Leader of the [=S.C.A.F.=] ground unit at Tau Volantis.

* BoomHeadshot: [[spoiler: How he kills Caufman, and then kills himself]].
* HonorBeforeReason: [[spoiler: Even after Caufman tells him that Serano knows a way to stop the Necromorph infestation, and the Codex is the key to salvaging everything, he still views the situation as beyond recovery and fulfills the Liquidation order anyway]].
** Justfied: [[spoiler: He doubtlessly knows by now that the Marker's energies can drive people insane in all sorts of ways; he naturally has to suspect the possibility that Serrano has been driven mad so that he ''believes'' there is a way to use the Codex to stop the Necromorphs.]]
* [[spoiler: MurderSuicide]]: [[spoiler: After executing Caufman, he turns to a Sovereign Colonies flag, salutes it, and then kills himself]].
* MyCountryRightOrWrong: Even when his orders involve [[spoiler: killing everyone under his command and protection, and then himself, he obeys without hesitation]].
* NiceJobBreakingItHero: [[spoiler: Could have stopped the Necromorphs from existing 200 years before the first game if he'd only trusted Serano's claims that the Codex could also be used to activate the "Necromorph Destroy Mode" of the Machine.]]
* PeelingPotatoes: In a log, he threatened to dole out this punishment to Caufman if he doesn't find the munitions depot key by sundown.
* PosthumousCharacter
* WellIntentionedExtremist: He got involved with the Marker experiments only to try and avert the looming energy crisis for humanity. Furthermore, the level 5 containment action is only to be activated in the case of an "extinction level" biohazard outbreak -- [[spoiler: and freeing the Brethren Moon would certainly count as that.]]
** It's shown that he had his doubts about the mission from the start; he would've preferred spending his time fighting what would eventually become [=EarthGov=], and clashed with Admiral Graves and Doctor Serrano over it.

!!Pvt. Tim Caufman
->Played by: Scott [=DeFalco=]

An S.C.A.F. Private, Caufman was part of a mission to Tau Volantis 200 years before the incident on the Sprawl.

* [[spoiler:DecoyProtagonist: He's the player character in the prologue, and like the rest of the S.C.A.F. expedition to Tau Volantis, he ends up getting killed.]]
* NewMeat: His inexperience shows through his constant panic.
* [[spoiler:ShootTheShaggyDog: He struggles to retrieve a cylinder containing data for Doctor Serrano, but is killed by General Maheed, who deletes all of the data before killing himself.]]

!!Pvt. Sam Ackerman

Another S.C.A.F. Private, he appears alongside Caufman if the prologue is played on co-op.

* [[spoiler: DroppedABridgeOnHim: Caufman may have avoided being crushed by the falling spaceship, but poor Ackerman didn't]].
* IDidWhatIHadToDo: You can find his logs in the Feeder barracks. He hid in a back room for days, and eventually locked his unit in when he ran. Since they were going crazy at the time, it's pretty justified.
* ImAHumanitarian: On the receiving end, since his insane unit attempted to eat him.
* OnlySaneMan: Of his unit, he was the only one not foolish enough to start eating Necromorph flesh to bolster their meager meals; conversely, he was the only one who didn't become a Feeder.
* RedOniBlueOni: The red to Caufman's blue, but with only a few lines of dialogue, it's hard to tell.

!!Admiral Marjorie Graves

The leader of the S.C.A.F. expedition to Tau Volantis, and commander of the ship CMS ''Roanoke''.

* RoomFullOfCrazy: Her quarters.
* SanitySlippage: Was one of the earliest sufferers in the S.C.A.F. forces. General Mahad would order her confined to her quarters, where she wound out writing "Turn it Off" in Marker script all along the walls.
* WellIntentionedExtremist: She sought the Markers in order to try and save humanity from the resource and energy crisis that had consumed them, and believed that finding the source of the Markers would greatly aid the Sovereign Colonies in their war.

!!Lt. Tucker Edwards

Pilot of the CMS ''Terra Nova''. When the Liquidation order came in, he killed his commander and barricaded himself in the ship's conning tower.

* DeadAllAlong: If Isaac chooses to go into the conning tower to nab Tucker's supplies, you'll hear audiologs from him, taunting you as you progress. Given that he lived 200 years ago, it's not much of a surprise when you get to the end of the road.
* {{Determinator}}: The tally marks on the floor indicates he lived ten years and seven months by himself after the order was given. Though this brings up the question, why didn't he just leave if there was a shuttle and he was a pilot? See Headscratchers/DeadSpace3 headscratchers page for more detail.
* [[spoiler:DrivenToSuicide: Eventually, loneliness and guilt overcomes him and he kills himself.]]
* MadBomber: Rigged bombs and other traps all around the conning tower.
* [[spoiler: OptionalBoss: Visiting the conning tower is entirely optional; you get quite a lot of loot for persisting through all his traps.]]
* VillainousBreakdown: [[spoiler:Not much of a villain, but the deeper you progress, the more unhinged his audiologs become. He starts out somewhat boastful, before just repeating that he doesn't want to die, before realizing that he should have accepted the Liquidation order.]]

!!Doctor Earl Serrano

The head researcher of the Sovereign Colonies expedition to Tau Volantis, the player can find audiologs throughout the game describing his discoveries and research on Tau Volantis.

* FlingALightIntoTheFuture: Not wholly intentionally, but his audiologs and research prove to be quite useful instructions for Isaac Clarke.
* OnlySaneMan: Unlike almost any other scientist who worked on the Markers, Doctor Serrano remained completely sane and rational. Of the Sovereign Colonies expedition, [[spoiler:he realized the truth about the Markers and attempted to activate the machine, however, Mahad's killing of Caufman and his own injuries stopped him from doing so. His audiologs tend to be quite helpful to Isaac Clarke, however.]]
[[/folder]]

[[folder:USM Eudora Crew]]
!!Sergeant John Carver
->Played by: Ricardo Chavira

An Earth Defense Force SpaceMarine from the [[SettlingTheFrontier colony world]] or Uxor, home of the Site 4 Marker. Carver lost his family after a Unitologist terrorist attack destroys the shroud surrounding the Marker. He later joins the crew of the USM Eudora with Isaac Clarke on a mission to Tau Volantis, hoping to destroy the Markers once and for all.

* AdultFear: After the Site 4 Marker was exposed, an outbreak of Necromorphs erupts and he cannot contact his wife and child, both of whom are completely vulnerable.
* {{Badass}}
* BrainsAndBrawn: In the co-op, he serves as the Brawn to Isaac's Brain.
* CoOpMultiplayer: Serves as player 2 in ''VideoGame/DeadSpace3'' dropping in and out of the action depending on the number of players.
* DeadpanSnarker
* [[spoiler:DeathEqualsRedemption]]: [[spoiler:A side mission reveals that following a domestic abuse incident involving his wife and son, Carver attempted to kill himself only for his wife to interrupt.]]
* {{Deuteragonist}}: Of ''VideoGame/DeadSpace3''.
* [[spoiler:DomesticAbuser]]: [[spoiler:A side mission reveals that Carver has been suffering from PTSD pre-game, and he even ended up assaulting his wife in front of his son. Despite therapy and understanding from his family, he later tried to kill himself out of guilt.]]
* DoomedHometown: His home planet of Uxor is destroyed by a Necromorph outbreak.
* [[spoiler:DrivenToSuicide]]: [[spoiler:An audio log on one of Carver's side missions reveals he was on the verge of killing himself from guilt before his wife unexpectedly walked in.]]
* FireForgedFriends: With Isaac. During their first conversation he tells Isaac quite flatly, "We're not friends," but by the end there is a mutual respect between them.
* GoodIsNotNice: He's willing to ShootTheDog if necessary, such as letting [[spoiler:Santos]] die, but the guilt clearly weighs on him.
* GoodScarsEvilScars: As the second protagonist in ''Dead Space 3'', his facial scars are considerably less horrific than other physical deformities in the franchise.
** It's not even as horrific as the other heroes! During the game's final cutscene, it's ''Isaac'' with a scalp gash, while Carver remains unblemished. This is true even during co-op play, when Carver is actually involved in the shooting. Throughout the game, only Isaac's character model of the two of them changes.
* [[spoiler:HeroicSacrifice]]: [[spoiler:Stays behind with Isaac to prevent Convergence]].
* {{Jerkass}}: He's taciturn, ruthless, and has pretty much zero people skills. If you play solo, he mostly just comes across as a goon with a gun, although he does PetTheDog once or twice such as when he backs Isaac up after [[spoiler:Isaac shoots Norton]]. The co-op game and side missions show him as having quite a lot of HiddenDepths, though.
* JerkWithAHeartOfGold: Though unpleasant and sometimes bitter, it's clear he's a good person at heart.
* ParentalNeglect: He wasn't the best father to his son, which features in his hallucinations.
* ParentsAsPeople: He wasn't able to spend as much time with his son as he would have like to, because of his job.
* ShellShockedVeteran: The Markers make Carver see remnants of his dead family and [[WarIsHell the horrors he has experienced as a soldier.]] [[spoiler:One of his side-missions reveals he's been suffering from PTSD and hallucinations before his wife and son were killed.]]
* SirSwearsALot: Swears even more than a freaked out Isaac Clarke.
* SpaceMarine: He's an Earth Defense Force soldier fighting Necromorphs throughout space.
* RedOniBlueOni: He's a rage-filled SpaceMarine, as opposed to melancholic engineer Isaac Clarke. [[ColourCodedForYourConvenience His visor even matches.]]
* RedEyesTakeWarning: Invoked. The visor lights in military [=RIGs=] all glow red to make them look more threatening.
* UnreliableNarrator: Playing as Carver results in the player seeing things that the less-insane Isaac cannot. [[spoiler:His second side mission begins with entering an elevator, only to find out in the end that they've been standing in the elevator for five minutes and Isaac's just waiting for him to push the button.]]

!!Capt. Robert Norton
->Played by: Robert Gant

Leader of [=EarthGov=]'s last remaining battalion after the Unitologists wiped out most of the military. He searches for Isaac on Ellie's behalf, as Isaac's the key to stopping the Necromorph threat to the galaxy.

* [[spoiler:BoomHeadshot]]
* CrazyJealousGuy: Acts this way to Isaac about Ellie, but assumes it's the other way around. Ellie even [[YoureJustJealous calls him out on it]] in ''Liberation'', but he shrugs it off with a KickTheDog.
* TheDanza
* DeadpanSnarker: Part of his Jerkass persona, he can't answer Isaac's questions without it dripping in sarcasm.
* [[spoiler:EnemyMine: How he views his deal with Danik against Isaac.]]
* FakeUltimateHero: Seems to believe he's the hero rather than Isaac, but shows signs of indecision, cowardice and possessive behaviour towards Ellie.
* {{Jerkass}}: To Isaac in ''3'' and to Carver and Ellie in ''Liberation'', with him telling Carver immediately after he had [[spoiler: to kill [[CameBackWrong his family]]]] that the Necromorphs are ClassifiedInformation despite Ellie objecting, and telling the latter to go and help the former [[KickTheDog because she "likes helping screwed up basket cases"]]. It leaves one wondering what exactly Ellie sees in him.
* [[spoiler:TheMole]]: [[spoiler:He tells Danik where Tau Volantis is and sells out Isaac to him in exchange for safety for Ellie and himself. Shockingly, Danik lied.]]
* [[spoiler:MurderTheHypotenuse]]: Norton attempts this [[spoiler:and becomes the target of it instead when Isaac kills him in self-defense.]]
* UngratefulBastard: After Danik [[spoiler:reneges on their deal and tries to kill them all]], Isaac saves Norton from Danik. Then Isaac rescues him again from a huge Necromorph. [[spoiler:Norton ''still'' tries to kill Isaac.]]
* WeHaveReserves: In ''Liberation'', this is his position about Carver's SanitySlippage and need to KillTheOnesYouLove. He says that Carver can be easily replaced with any other soldier... even though [[TheRemnant he can't]], which seriously pisses off Ellie.
* {{Yandere}}: [[spoiler:Is willing to kill Isaac and sell out the whole universe to keep Ellie for himself]].

!!Mark Rosen

Crewmember of the USM Eudora.

* {{Jerkass}}: ''Very'' hostile against Isaac, to the point where Isaac even outright calls him an asshole. Likely an imitation of his superior's own {{Jerkass}} attitude towards Isaac.
* MauveShirt: Played with. There is considerable effort to keep them alive [[spoiler: only to be killed off violently along with Locke during the Crozier's crashlanding]].
* [[spoiler: OffWithHisHead: Gets his head ''sliced'' in half gruesomely by debris on the way down to Tau Volantis.]]

!!Locke

Crewmember of the USM Eudora.

* LastNameBasis: Her first name is never revealed in the game.
* MauveShirt
* [[spoiler: StuffBlowingUp: What kills her during the descent down to Tau Volantis.]]
[[/folder]]

[[folder:Marker Ops Team]]
!!Jennifer Santos
->Played by: Michelle Johnson

An engineer Ellie Langford brings along to Tau Volantis to help figure out how to get rid of the Necromorphs.

* BaldWoman
* [[spoiler: [[BlackDudeDiesFirst Black Lady Dies First]]: Inverted, she is the last character of Isaac's group to die in ''3''.]]
* NightmareFetishist: She thinks the Nexus is beautiful, and she sounds a little too eager when she tells Isaac that they'll have to crawl into one.
* [[TheSmartGuy The Smart Gal]]: Buckell even calls her the "little lady with the big brain."


!!Austin Buckell
->Played by: Frank Ashmore

A Marker researcher Ellie Langford brings to Tau Volantis.

* {{Badass}}
** BadassGrandpa
* CoolOldGuy
* [[spoiler: HeroicSacrifice: The team manages to find winter suits in an outpost but there weren't enough for everyone. He volunteers to be left behind without a suit.]]
* [[spoiler: ImColdSoCold]]
* NiceGuy: One of the friendliest characters in the franchise to Isaac, [[spoiler: [[TooGoodForThisSinfulEarth which may explain why he unfortunately was the first one to die when they actually reach the surface of Tau Volantis]].]]
* [[spoiler: ObiWanMoment: Out of all the characters of the ''Dead Space'' universe, Buckwell arguably has the most peaceful death. He isn't torn apart by Necromorphs or shot, but dies of hypothermia and existing wounds.]]
[[/folder]]

[[folder: Members of The Circle]]
A violent and fanatical sect of Unitology, the Circle rebelled against [=EarthGov=] following the Marker experiments that occurred in ''2''. They serve as the primary human antagonists in ''3'', seeking to kill Isaac Clarke and bring about Convergence to humanity.

'''In General'''
* ChurchMilitant
* DrivenToSuicide: Several times on Tau Volantis, Isaac can stumble across a lone soldier who screams a Unitologist proverb before shooting himself. At one point, he witnesses several members performing a ritual before they all slit their throats.
* EliteMooks: Certain Circle troops wear black gear and have more durability. They also tend to carry heavier weapons.
* EvilVersusEvil: [=EarthGov=] undoubtedly trampled on the rights of its citizens, performed unethical experiments, and manufactured Markers like crazy. The Circle ''overthrows them'', guns down civilians left and right, and deliberately engineers Necromorph outbreaks.
* EvilerThanThou: Unitologists weren't a pleasant bunch to begin with, but The Circle makes mainstream Unitologists look like saints in comparison. Also pull this off by toppling [=EarthGov=].
** The Cultists in ''Awakened'' are this to the members of the Circle who ''haven't'' lost their minds.
* GlassCannon: As they are normal human beings, they are much easier to kill with gunfire than most Necromorphs. However, since they're similarly armed, they can be a substantial threat.
* NGOSuperpower: Have the resources to undermine and overthrow [=EarthGov=].
* SanitySlippage: The DLC ''Awakened'' features Circle members who have completely lost it, outright worshipping Necromorphs (when in the base game artifacts show that they previously had considered them abominations caused by heretics messing with the Markers), and engaging in self-mutilation.

!!Jacob Arthur Danik
->Played by: Simon Templeman

Leader of The Circle. After bringing ruin to [=EarthGov=] and its colonies, he hunts down Isaac as he's the only one capable of stopping his plan of bringing Convergence to the galaxy.

* BigBad: Of ''Dead Space 3''.
** NonActionBigBad
* DoesThisRemindYouOfAnything: In-universe, he asks this of Isaac concerning the Markers and their source, [[SuspiciouslySpecificDenial completely scientifically]] noting that they [[{{God}} lead man toward a higher purpose]] [[InMysteriousWays that isn't entirely clear to begin with]].
* [[spoiler:EnemyMine: With Norton temporarily against Isaac.]]
* EvilBrit
* FauxAffablyEvil: He speaks in a polite and refined manner, and even hands out compliments to his adversary. However, he usually follows it up with a death threat, and his compliments always have an smarmy, insincere tone to them.
* TheFundamentalist: Although he claims what he does is ForScience, every word out of his mouth hints at religious fanaticism that he denies.
* HumansAreTheRealMonsters: Seems to hold firm to this belief.
* {{Hypocrite}}: When Danik tells Isaac to stop messing with things he doesn't comprehend, Isaac's quick to point out the hypocrisy.
* [[spoiler:KarmicDeath: Bites it by being impaled with a stalactite that falls due to him turning off the machine that was preventing Convergence]].
* KnightTemplar: Like all Unitologists, he truly believes he's doing the right thing by forcibly "ascending" all of mankind through Convergence.
* ManInWhite
* SinisterShades
* SmugSnake: When things are going his way, he tends to gloat and carry a polite facade. When things ''don't'' go his way, however, the facade quickly breaks down.
* [[spoiler: StalactiteSpite: His death, immediately after turning off the Alien Machine.]]
** [[spoiler: ImpaledWithExtremePrejudice: In a near standing position.]]
* [[spoiler: TheUnfought: As seen above, he gets impaled by a stalactite before Isaac or Carver can kill him.]]
* WellIntentionedExtremist

!!"The Prophet"

Leader of a cult of followers in the Circle who believe that they can ally themselves with the Necromorphs by becoming like them through bodily mutilation. He serves as the DragonInChief of ''[[PlayableEpilogue Dead Space 3]]: [[DownloadableContent Awakened]]''.

* AxCrazy: Considering his plans, this probably shouldn't be a surprise.
* BandagedFace: Though considering [[SelfHarm his methods]], this is probably better than [[NightmareFace the alternative]].
* DarkMessiah: [[spoiler:The Brother Moons]] even call him "the prophet" to their "god".
* DragonInChief: Of ''Awakened'', sort of. He isn't in direct contact with [[spoiler:the Brother Moons]], but he is trying to help the goal along in his own way.
** FinalBoss: Of ''Awakened''.
* TheFundamentalist: Even moreso than Danik.
* ImplacableMan: Due to Isaac and Carver's {{Hallucinations}}, he appears capable of FlashStep and NighInvulnerable, though it's highly likely they are simply missing. [[spoiler:Once they manage to subvert the Moons' hold on him and wound him, things get a lot easier.]]
* MadeOfIron: When Isaac and Carver manage to hit him, he still takes a lot of punishment for someone who never wears a shirt.
* [[spoiler:MouthOfSauron[=/=]MeatPuppet: For the Brother Moons.]]
* MultiArmedAndDangerous: Subverted. He wants this, having put Slasher arms into his back, but he doesn't actually have it.
* NoNameGiven: Even the title, "the Prophet" is only given to him by [[spoiler:the Brethren Moons]] and he's only called it once in the entirety of the [=DLC=]. One of the Unitologists, Randall Carr, knows most of the people in Danik's crew and not even he can figure out who the Prophet is any more.
* SelfHarm: How he seems to have put the Slasher arms on his back.
* TimeStandsStill: Has access to a Stasis module. How he uses it is unknown.
* TouchedByVorlons: [[spoiler: He seems to have some control over the hallucinations that Isaac and Carver suffer as a result of his connection to the Moons.]]
* WalkingShirtlessScene: Probably relates to his SanitySlippage.
* [[spoiler:ZeroEffortBoss: Once he's actually found after the LetsYouAndHimFight and his wounding in a hallucination fight, he doesn't even fight back. He just sits on his knees, bowing and mumbling his MadnessMantra over and over like his followers until Carver and/or Isaac kills him. The two don't even comment on killing him.]]

[[folder: Necromorphs]]
Dead bodies reanimated by an alien virus and turned into giant monsters that go out and kill everything, making more Necromorphs.

'''In general'''
* BizarreAlienBiology: Doesn't get much weirder than [[TheVirus hive-minded alien bacteria that reanimates necrotic flesh]]. Also the fact that limbs are their weakness; since the only goals of the Necromorphs are to kill and further spread the infection, by removing their limbs and thus their mobility, there's little point in an infected individual remaining active. Isaac might not be so much killing them, but simply rendering them ''[[FridgeHorror dormant]]''.
* BodyHorror: Almost all of them are, in some form, human at one point, although the larger ones tend toward several corpses fixed together.
* CreepyLongFingers
* ExactlyWhatItSaysOnTheTin: Most of their names are basically exactly what they are or do.
* HumanAliens: Completely subverted, but in an ironic way, since all the Necromorphs are made from human corpses and have ''just enough'' recognizable human parts for a fully-horrific UncannyValley effect.
** After the going into the EyeScream machine in ''VideoGame/DeadSpace2'', their screams and grunts sound ''distinctly'' less animalistic and more like the shrieks of humans in agonizing, unconscionable pain.
* NightmareFace: All of them, since they are based on human bodies.
* OurZombiesAreDifferent: Type P. The Necromorphs are spread by a virus that reanimates and mutates dead bodies. But the person has to be dead for it to work, no slowly becoming weaker until they die. That said, the person can be dead remarkably recently (as in immediately) and it still counts, which is probably why the Necromorphs infect by stabbing with giant mandibles.
* PerpetualMotionMonster: Necromorphs don't rot and can survive centuries with little to no problem, suffer no damage from being frozen, and to top it off rarely if ever seem to need to eat.
* SlidingScaleOfUndeadRegeneration:
** Type II. Necromorphs, despite their appearance, do not rot and appear to get stronger the longer they last; Necromorphs formed 200 years ago are equally as potent as Necromorphs infected in the modern day. Shooting them in the midsection does little damage, while dismembering them only disables them; they can get reinfected and come back later. Only by destroying the entire body (whether it be by grinding it up, melting it, or through gratuitous use of Isaac's stomp ability) will permanently put an end to them.
** The Hunter, Ubermorph, and Regenerators take this even further, being Type [=IVs=] capable of rapidly regenerating damaged limbs and surviving all but catastrophic damage.
* TheVirus: The Necromorph Recombination Virus. Interestingly it only affects dead bodies, which the already-created Necromorphs are ready to make.
* ViralTransformation: Cranked up to 11.

!!Slasher

The most common type of Necromorph as well as the first type Isaac encounters. Attacks with razor-sharp arm blades.

* EliteMook: The Enhanced version are much faster, have more health and deal more damage.
* MultiArmedAndDangerous: They have a pair of vestigial arms sprouting from their abdomens in addition to their original arms, which are mutated into swords. In ''[=DS3=]'', they have a couple more sets when encountered after they've been freeze-dried for 200 years.
* PlayingPossum: One of their favorite tactics. If you see an intact Slasher corpse it's probably not dead...
* SinisterScythe: Their arms and their primary weapons.

!!Spitter

A variant of Slashers made from female corpses that spit balls of acid at their prey.

* BreathWeapon: The balls of acid they spit.
* FanDisservice: In ''[=DS2=]'' they appear completely nude, with their original arms pulling their chest muscles apart.
* SinisterScythe: Like Slashers, they prefer to get up close and personal, occasionally stopping to spit when Isaac's too far away.

!!Leaper

A scorpion-like Necromorph that attacks with its large tail.

* BewareMyStingerTail: Pretty much its only way of attacking.
* EliteMook: The Enhanced version has more health and damage output.
* LightningBruiser: In the second game, which significantly beefed up their speed and power.
* [[ScaryScorpions Scary Scorpion]]: Undead corpse, human-based scorpions, anyway.
* WallCrawl

!!Lurker

A disturbing Necromorph created from infants or dogs that can attack with its tentacles as well as barbed projectiles.

* BlackComedy: Isaac's Lurker kill animation basically has him try to kick the zombie baby for a field goal.
* BewareOfViciousDog: ''Dead Space 3'' shows that dogs are suitable candidates for Lurker transformations as well as humans.
** RaisingTheSteaks
* CombatTentacles: Three. Cutting them off is an excellent way to kill them.
* EliteMook: The Enhanced version has more health and damage output.
* FetusTerrible
* UndeadChild: When made from a baby.
* WallCrawl

!!Infector

A Necromorph whose sole purpose is to spread the infection. While it is physically weak, it is a credible threat thanks to its ability to turn corpses into Necromorphs.

* CompositeCharacter: In ''3'', Infectors are dramatically changed, resembling Swarmers in function. They travel in large groups, are much smaller than before, and attack like Swarmers.
* {{Expy}}: In ''3'', they get a redesign; instead of a large mass of flesh with a proboscis, Infectors are now much smaller, and bear a great resemblance to [[VideoGame/HalfLife headcrabs]].
* GlassCannon: It doesn't take much to kill one, but if given enough time it can revive a whole room full of Necromorphs.
* MookMaker: They can revive the dead bodies of the crew as Necromorphs, typically EliteMooks.
* StarfishAliens: Unlike many Necromorphs, these are just....flaps of skin and a proboscis.

!!Pregnant

A bloated-looking Necromorph that carries Swarmers in its stomach. Damaging its belly will release the Swarmers, making it a difficult Necromorph to deal with, especially in large groups.

* AttackItsWeakPoint: Subverted, unlike most others. Shooting a Pregnant in the stomach, the most obvious weakpoint on it, is one of the worst things someone can do when facing one.
* DeadWeight: Although being heavily bloated doesn't slow them down much.
* KillItWithFire: The flamethrower, though objectively a lousy weapon in the first game, has the benefit of burning their Swarmers to death as they pour out.
* OutsideTheBoxTactic: The Force Gun can be used to shoot Pregnants even in the stomach and avoid releasing Swarmers.
* MookMaker: Shooting them in the stomach unleashes Swarmers.

!!Exploder

A very dangerous Necromorph with a bloated (and highly explosive) arm which it detonates in a suicide attack if it gets too close.

* ActionBomb: If that wasn't bad enough, they often appear in large groups. On the plus side, friendly fire is in full effect here, and you can even steal the bomb if you sever it from the arm.
* AttackItsWeakPoint: That big, glowing, orange thing on its arm? It might be a good idea to shoot it before it gets too close.
* GlassCannon: Two shots will put one down. You don't even have to aim since it's so thin. It's basically a walking stick with a bomb attached.
* TookALevelInBadass: To a very minor degree, but in ''3'', they now crawl, dragging their explosive behind them, and move faster than before; this makes hitting them before they get in close slightly harder.

!!Divider

A tall, thin Necromorph that splits into several smaller Necromorphs upon being attacked.

* ChekhovsSkill: In ''Dead Space 1'' and ''2'', the head part had a move where it jumped on Isaac, and could replace his head. This is their gimmick in ''3'', able to revive fallen enemies, including gun-wielding ones.
* OutOfFocus: They were an uncommon enemy in the first game, but still showed up often enough that you kept an eye out for them. In the second, there are a few separate parts and maybe one or two complete Dividers in the whole game. They come back into the spotlight in the third with a different gimmick, their old gimmick of "changes when dismembered" having been given to the [[TheyLookLikeUsNow Waster]]. Only Divider heads looking for new bodies show up, with no intact Dividers to be found.
* PuppeteerParasite: The "head" piece. Which makes for one of the most disturbing deaths in the entire game. In the third game, this is their new power; Divider heads can show up after a battle with Unitologists and posses their corpses by decapitating them and replacing the head.
* TheWormThatWalks: It's a bunch of thin, tentacle creatures (one of which is wearing a skull) latched to each other to form a monster, and breaks apart into those creatures when damaged enough.
* ItCanThink: If the head part hijacks a corpse that has a firearm, it will know how the weapon works and open fire on Isaac, although their aiming skills are very poor

!!Twitcher

Soldiers whose stasis modules fused with them upon being turned into Necromorphs, making them extremely fast.

* BulletTime: Thanks to the stasis modules fused with their flesh.
* FragileSpeedster: Can be killed in one shot with the best weapons... if you can hit them.
* SuperSpeed
* NightmareFace: Even more so than most of the others in ''Dead Space 1'', as due to the violent fusion between their flesh and the stasis module, their faces are completely static.
* YouAreAlreadyDead: One particular death scene has a Twitcher kill Isaac so fast that when he raise his weapon to counter his entire body falls apart.

!!Guardian

A mass of flesh attached to a wall that spews out smaller, weaker Necromorphs to defend itself. Often encountered one at a time, but can sometimes be found in pairs. One of the most extreme cases of BodyHorror in the franchise for a single human body.

* AndIMustScream: And scream it does. Apparently, the Guardian is still alive, and in hideous agony. It is also unable to move. [[MercyKill Luckily, you can kill it.]]
* CombatTentacles: Used to kill Isaac if he comes into close proximity with one, and seemingly made from intestines.
* InstantDeathRadius: Getting too close has them decapitate Isaac with a tentacle.
* MookMaker: Constantly spits out tentacle pods to help defend itself.
* OneHitKill: Its only direct attack.
* ScreamingBirth: The Guardian constantly lets out an agonized wail, and it goes up an octave when it spawns a Pod.

!!Swarmer

Tiny, swarming Necromorphs that, despite their small size, can easily overwhelm Isaac with sheer numbers.

* CompositeCharacter: The new Infectors in ''3'' are basically a combination of Swarmers and the original Infector; they are small, appear in large groups, and their attack is lifted directly from the Swarmers.
* DeathOfAThousandCuts: Individual Swarmers do pitiful damage and can be swatted off before they even do damage. However, as their name suggests, they're much more deadly in groups, and can severely injure or kill Isaac if he's caught in a large swarm.
* TheSwarm: ExactlyWhatItSaysOnTheTin.

!!Brute

A massive and deadly Necromorph that uses brute force as its only tactic.

* AttackItsWeakPoint: Its armored shell blocks most frontal attacks, but its joints and entire back side are vulnerable.
* EliteMook: Even more so in its Enhanced version.
* LightningBruiser
* MadeOfIron: Most of its body, aside from a few weak points, are completely immune to damage. When playing on hard or impossible difficulty, one main concern isn't its attacks, but running out of ammo white fighting one. Hope you saved up some stasis so you don't have to worry about missing...
* NoHoldsBarredBeatdown: One shows up out of nowhere on the Valor and delivers one to [[spoiler:Hammond]]. They can also do this to Isaac.
* [[TopHeavyGuy Top Heavy Abomination]]: Somewhat similar to a [[VideoGame/Left4Dead Tank.]]

!!Wheezer

This type of Necromorph only appears in one chapter, whose only form of attack is slowly poisoning the air. They are often supported by more combat-oriented Necromorphs.

* TheCameo: Makes an appearance in ''Dead Space 3'' in a co-op mission.
* DeadlyGas: Its only form of attack. Standing next to one too long will suffocate Isaac.
* GottaKillEmAll: Their only appearance consists of this, in order to keep the air in the USG Ishimura safe to breathe.
* MookMaker: A variation. Killing one will summon several Necromorphs to Isaac's location.
* VaderBreath: Easily located by their loud, well, ''wheezing'' gasps for air.

!!Drag Tentacle

Presumably part of a larger Necromorph, the Tentacle grabs Isaac and drags him towards its lair unless Isaac can shoot it off.

* AttackItsWeakPoint: Because this is the only way to hurt it and if you don't you be dragged into a hole in the wall and killed horribly.
* AttackOfTheMonsterAppendage: The Tentacle. Type 1, as you'll never see the rest of his body.
* HopeSpot: Often when Isaac is dragged all the way back to their hole he tries some desperate form of escape only to be killed almost immediately. When the second tentacle that appears pulls him near the hole it loses its grip just long enough for Isaac to stand back up before brutally grabbing his head and yanking him the rest of the way in.
* InterfaceScrew: Whenever one grabs Isaac it messes with his aiming controls, making it much harder to hit. However, the weakpoint is very large.
* NothingIsScarier: We never do get to see what is on the other end of this thing... but Isaac might.

!!Puker

A Necromorph whose main attack is vomiting caustic bile at Isaac, as well as a ball of caustic material that slows Isaac down, allow it to close the distance.

* CastFromLifespan: These necromorphs are severely damaged by the acid they spew. WordOfGod says they eventually liquefy completely.
* ExactlyWhatItSaysOnTheTin: They, well, ''puke'' on you.
* HollywoodAcid: Does a lot of damage.
* PoisonIsCorrosive: The Puker spits highly acidic bile at its enemies, reminiscent of [[VideoGame/Left4Dead The Spitter]]. While it's sizzling any Human player's armor, he's unable to run. In multiplayer, this can range from annoying (on the objective carrier, who can't run anyway) to lethal (human players rushing toward an escape point).
* VomitIndiscretionShot

!!The Pack

Children that have been turned into Necromorphs. Weak, but attack in swarms.

* EnfanteTerrible
* JustAKid: Being kids, they are small, and a fairly easy kill individually... but they are fast, and always attack in groups.
* TheSwarm
* UndeadChild
* ZergRush

!!Crawler

Tiny infant Necromorphs whose bodies are filled with a volatile, yellow fluid that explodes when Isaac is close. They are tiny, making them hard to hit, and they come in packs, but can be killed easily.

* ActionBomb: They explode. Like the Exploders, a headshot will put them down and leave the bomb intact for you to use.
* EnfanteTerrible
* UndeadChild
* WaveOfBabies: How they tend to attack. However, a DownplayedTrope, in that they tend to come only two or three at a time.

!!Cyst

Stationary Necromorphs that spit out an explosive, living pod when something gets too close.

* LandMineGoesClick: They're essentially organic land mines, and instead of going "click," they gurgle and hiss loudly.
* UnfriendlyFire: They go off regardless of what touches them, whether it's a living human, an inanimate object, or another Necromorph. Their own pods also kill them as well if the Cyst is too close to another surface or if they're on the ground and gravity brings the pod back down.

!!Stalker

Necromorphs that resemble velociraptors. They attack by running at high speeds toward Isaac, ramming him, and running back. They love to attack in large rooms filled with boxes to hide behind, though you can find an odd Stalker in a random room once in a while.

* EverythingsBetterWithDinosaurs: Well, for a certain definition of "better".
* GetBackHereBoss: They only show themselves to attack you, and you have a window of about two seconds to hit them (preferably with a Stasis blast) before they tackle you and retreat to cover for another round.
* RaisingTheSteaks: Appears to be partially constructed from animals.
* RaptorAttack
* ShoutOut: The achievement for beating your first encounter with them is called "[[Film/JurassicPark Clever Girl]]."

!!Tripod

A large, three-legged Necromorph made from several corpses fused together. Very big and strong.

* AttackItsWeakPoint: There's an obvious yellow bulb on its tongue.
* EliteMook[=/=]MiniBoss: Encounters with type of Necromorph tend to play out like this, from a fight with one of them to one with several at once.
* LightningBruiser: Moves fast and hits like a truck.

!!Flyer

A small weak necromorph that, like its name implies, flies around and tries to attack with its tail. Only appears in ''VideoGame/DeadSpaceExtraction''.

* {{Flight}}: The only known Necromorph capable of this.

!!Grabber

A necromorph that can extend its neck to attack from a distance. Encountered only in ''VideoGame/DeadSpaceExtraction'', though it appears in ''WesternAnimation/DeadSpaceAftermath''.

!!Nest

A powerful Necromorph that is very similar to a Guardian. In fact, it's strongly implied that it is the female version of a Guardian.

!!Waster

A Necromorph that takes the form of a decaying human wielding melee weapons.

* DualWielding: Always carries two weapons, whether it be ice picks, axes, bone saws, or wrenches.
* {{Expy}}: Of a Divider, in how they change their form once they lose their legs, growing tentacles from the stump.
* HumanoidAbomination
* ImprovisedWeapon: The only Necromorph thus far to use an actual weapon aside from what they spit or have attached to their bodies.
* ProductionNickname: They were initially called the "Fodder".
* TheyLookLikeUsNow: Looks like a human.

!!Feeder

Naked, emaciated Necromorphs resulting from humans desperate enough to eat Necromorph flesh.

* BoomHeadshot: Surprisingly, one of the only Necromorphs where headshots are the best way to take them down, tying into their TechnicallyLivingZombie status. The regular variants are weak to pretty much any attack, but when facing [[EliteMooks Enhanced]] versions, aiming for the head is a must.
* DisabilitySuperpower: They're nearly blind, but have acute hearing to make up for it.
* {{Expy}}: A taller, more durable version of the Pack.
%% * FragileSpeedster: See TechnicallyLivingZombie.
* FullFrontalAssault: They aren't wearing anything at all, though there's not much left to show.
* HorrorHunger: People becoming them retained mental capacity to some degree. They just seemed willing to eat [[ImAHumanitarian anything]].
* MoreTeethThanTheOsmondFamily: Has extra teeth formed from the jaw bones.
* TechnicallyLivingZombie: Unlike other variants, Feeders appear to be just mental transformations and extended life. This extends to their FragileSpeedster status.
* YouAreWhoYouEat
* ZergRush: Attack aggressively in waves.

!!Alien Necromorphs

Necromophed members of the original alien species that once ruled Tau Volantis, these abominations have been waiting for over 2 million years for new prey, and they weather damage as much as they've weathered time.

* AirborneMook: One variation is a sort of flying jellyfish, encountered during Zero-G sequences. It has float-sacs and four tentacles that throw [[OrganicTechnology homing wisps]] or smack Isaac when he flies to close.
* EnfantTerrible: The Crawlers that it spawns from its chest? They're made of the Alien species' spawn, just like they were made with human infants before.
* {{Expy}}: The 'Brute' variation is much like the old Brute. It's slow moving but can quickly charge, has tremendous resilience, and has ability to spawn exploding pods from a orifice in its chest.
* MadeOfIron: Although they don't possess the indestructible plates of the older brutes, they also lack any [[AttackItsWeakPoint glowing yellow weak point]] to attack, meaning killing one comes down to shooting at one's limbs until the creature finally drops dead.
* PinataEnemy: The Alien Brutes drop ''three'' items upon death.
* StarfishAliens: Or Starfish Necromorphs, due to the species that they were formed of. However, their infections parallel our own; their facial structure looks relatively intact and have similar growths fusing and adding new limbs as suited.

!!Regenerator

More of a scheme of Necromorph than a type in and of itself, this is a typically bipedal Necromorph that takes on a variety of names depending on its incarnation. The main constant, however, is that it can [[HealingFactor regenerate lost limbs]], making it nearly impossible to kill.

This is a boss-type enemy. For the example in ''Dead Space 1'', see "The Hunter" under that section. For the example in ''Dead Space 2'', see "The Ubermorph" under that section. For the examples in ''Dead Space 3'', see "The Regenerators" in that section.
----
* {{Determinator}}[=/=]ImplacableMan: Due to being nearly impossible to kill, it doesn't see much reason not to try following a target forever.
* MenacingStroll: Their method of movement.
* MightyGlacier: Powerful, but slow and easy to cripple (about halfway been a mook and EliteMook in damage resistance). It just keeps coming, though.
* NighInvulnerability: Due to a healing factor, it cannot be destroyed by conventional means.
** ShapeShifterBaggage: With varying plausibility, they regenerate limbs seemingly from within their own bodies.
* SlidingScaleOfUndeadRegeneration: Type 4, being able to regenerate from lost limbs.
* SuperPersistentPredator: It does not stop coming ''ever''.
* SuspiciouslySimilarSubstitute: The various types each mimic the first game's "Hunter" in how they move and their [[HaveANiceDeath kill animations]].

[[spoiler:The BiggerBad species of the series, these are the culmination of Convergence events, as Necromorph organisms so large that they can easily be misconstrued as "moons".

[[/folder]]

[[folder: Boss Necromorphs in ''Dead Space 1'']]
!! The Hunter

A special type of Necromorph created by Dr. Mercer, made from injecting Necromorph tissue into a live victim's skull. It constantly regenerates limbs, requiring Isaac to stop it using his environment. For the type, see "Regenerator" in the Necromorph section.

* ImplacableMan: The Hunter Necromorph reappears throughout the levels it's in (albeit in fixed locations), regenerates from any damage you do to it, and even returns a few levels later to menace you after you think you've stopped it by trapping it in a cryogenic freezer.
* KillItWithFire: Proves to be the only way to kill it.

!! The Leviathan

A Necromorph that has barricaded itself in food storage and is poisoning the Ishimura's atmosphere as part of a biological terraformation. Takes the form of an enormous wall of flesh, with a central orifice surrounded by tentacles. Fights Isaac by flailing its tentacles and shooting exploding pods at him.

* CombatTentacles: Three. After destroying them it reveals its weak point allowing Isaac to finally kill it. Of course, then the tentacles come ''back''.
* DamageSpongeBoss: It's not uncommon to waste all your ammo trying to kill this thing. It's so bad that ammo pickups and explosive canisters spawn periodically and the boss can be damaged by his own projectiles.
* TacticalSuicideBoss: The explosive orbs it spits at you can be thrown back with Kinesis, not to mention the room is filled with explosives.

!!The Slug

A huge Necromorph that attacks from outside the Ishimura by flinging debris. Isaac fights and kills it with the ship's turret system.

* CombatTentacles: It uses them to pitch debris at you, which you must destroy if you don't want the hull to rupture.
* [[spoiler:NiceJobFixingItVillain: Considering Kendra's status as TheMole, and how the ''Valor'''s mission would LeaveNoWitnesses, its presence may have saved Isaac's life.]]
* SpannerInTheWorks: Its presence on top of the communications array prevents Kendra from being able to radio a warning to the ''Valor''.

!!Hive Mind

The Hive Mind is the last boss in the game and has been controlling the other Necromorphs through telepathy. It [[spoiler:kills Kendra after she betrays Isaac and attempts to make her escape]] before turning on Isaac himself. After a heated battle, Isaac manages to destroy it and barely escapes with his life.

* CombatTentacles: Its favorite type of melee attack is swinging its tentacles at Isaac. After dealing a significant amount of damage it will grab him with them and lift him up in the air where he'll have a short amount of time to destroy its remaining weak spots or be ripped in half.
* EldritchAbomination: Looks more like one than any other boss Necromorph in the game.
* FinalBoss: Of ''1''.
* HiveMind: Its name alone is all you need to know.
* MookMaker: Starts spiting out Pregnants if you take too long to defeat it.
[[/folder]]

[[folder: Boss Necromorphs in ''Dead Space: Extraction'']]
!!The Urchin

A large Necromorph of unknown origin that appears in chapter 6.

!!The Spider

A massive Necromorph that that is found crawling on the exterior of the USG Ishimura. Serves as the boss of chapter 9.
[[/folder]]

[[folder: Boss Necromorphs in ''Dead Space 2'']]
!!The Tormentor

A huge Necromorph that attacks Isaac in the Church of Unitology basement. Isaac has to shoot off one of its arms, then run as fast as he can to escape it.

* CutsceneBoss: Gameplay wise, it's not so much a battle as a timed aiming minigame. Shoot the right target before it can eat you.
* GiantSpaceFleaFromNowhere: After dodging the gunship, it turns out the Tormentor's lurking in the basement of the Church of Unitology for... some reason, tries to eat Isaac, and ends up being killed in a massive explosion.

!!Ubermorph

A Necromorph Isaac encounters near the end of ''Dead Space 2''. Like the Hunter, it is impossible to kill by normal means; unlike the Hunter, its origin is unknown. It is also the only Necromorph that looks like an alien, not a mutated human.

* LordBritishPostulate: You're supposed to just run away from the [[ImplacableMan Ubermorph]] and continue on to the final boss, yet players have found that it can be killed permanently by [[spoiler:pushing it into a fan in the last room it appears in]]. This is probably a glitch; it isn't indicated anywhere in the game that you can kill it like this, it doesn't appear after this anyway, and it disappears instantly upon touching the fan instead of playing a death animation. It can also be killed by [[spoiler: [[http://youtu.be/mchPnvqPBiw?t=2m10s abusing pathfinding glitches and collision detection to crush it with an airlock door]].]]
* PaletteSwap: It is literally the Hunter with a different [[IncrediblyLamePun skin]]. It even shares the death animation with the Hunter.

!![[spoiler: The Golden Marker]]

[[spoiler: Once the Convergence Event starts, the Golden Marker tries to get Isaac to kill himself so it can be made whole, via a BattleInTheCenterOfTheMind. In the battle, Isaac has to fight off swarms of The Pack while shooting and dodging the Nicole hallucination.]]

* AttackItsWeakPoint: After shooting [[spoiler:Nicole]] enough, the central "heart" is revealed, giving you about 5 seconds to damage the boss before [[spoiler:Nicole]] reforms.
* BattleInTheCenterOfTheMind
* EvilCounterpart: [[spoiler:To Marker 3A on Aegis VII. While that one was one of the Markers working to avoid Convergence and wanting to be put back on its pedestal, this one tries to force it forward.]]
* FinalBoss: Of ''2''.
* FlunkyBoss: Spawns waves of the Pack to deal with you.
* OneHitKO: Touching [[spoiler:Nicole]] instantly kills you. Fortunately, the boss is very slow, though [[spoiler:she]] can teleport closer to you if you get too far away.

[[folder:Boss Necromorphs in ''Dead Space 3'']]
!! The Regenerators

A Necromorph type first encountered about the USM ''Terra Nova''. Like the Hunter and Ubermorph before it, it regenerates lost limbs at a rapid pace, making killing it permanently a difficult proposition. Unlike the Hunter and Ubermorph, there's more than one Regenerator.

* BonusBoss: Although the first set of Regenerators (aboard the ''Terra Nova'') are unavoidable, a later set is encountered in an optional mission towards the end of the game.
* KillItWithFire: [[spoiler:Subverted. These guys are ''fireproof''.]]
* PaletteSwap: Looks a bit more like the Hunter than the Ubermorph, except its skin is very pale and has Marker runes carved all over it.

!!The Snow Beast

A large Necromorph that is encountered on Tau Volantis.

* CombatTentacles: Has a trio of them on its back, plus another set in its face.
* CowardlyBoss: [[spoiler: In the first two encounters, it retreats after enough damage has been done]].
* GiantEnemyCrab
* [[spoiler:[[HalfTheManHeUsedToBe Half the Crab It Used to Be]]]]
* HealingFactor: Can regrow its back tentacles repeatedly.
* SuperPersistentPredator: [[spoiler:It attacks Isaac shortly after he crashes on the planet and continues to stalk him throughout most of the game. Even after he fights it off several times, it keeps hunting him.]]

!!The Nexus

Several giant Necromorphs Isaac and Ellie find frozen on Tau Volantis. Isaac has to explore the inside of one to locate the origin of the Markers, which thaws it out.

* {{Expy}}: Similar to the HiveMind from the first game; even the game's achievement text calls it the Hivemind, probably because it ''is'' one, albeit one made from aliens, not humans.
* MookMaker: Similarly to the Hivemind, except it spawns Enhanced Feeders.
* WombLevel: Twice. During the second time, you are promptly [[SwallowedWhole swallowed whole]] and forced to kill it from the inside.

!![[spoiler:The Moon]]

[[spoiler:A [[GeniusLoci Brother Moon]] that has gone into hibernation due to the machine that turned Tau Volantis into an ice planet, this unfinished [[UltimateLifeForm Convergence Necromorph]] is masquerading as Tau Volantis' broken moon, using the Marker signal to call other humans to it to wake it up and "[[ArcWords make it whole]]." Due to this, it serves as a BiggerBad, manipulating [=EarthGov=], Unitology, and many more for its cause.]]

* [[spoiler:BiggerBad: Of the entire series up to 3, being the source of the Marker signals in human space.]]
* [[spoiler:[[PlanetEater Biosphere Eater]][=/=]PlanetLooters: It's presumed that after finishing its own birth, it would have roamed the galaxy, homing in on humanity's Marker signals and ''eating everyone''.]]
* [[spoiler:TheChessmaster: Manipulated pretty much everyone in the series at one point or another until 3. Those who it didn't tended to end up dead, except for a select few.]]
* [[spoiler:ChekhovsGunman: Seen prominently throughout the game, shown on various posters and promotional material, literally hiding in painfully obvious sight from the protagonists throughout the entirety of the game.]]
* [[spoiler:DidYouJustPunchOutCthulhu: Isaac and Carver, two characters who barely measure up to the size of its ''teeth'', manage to not only go toe-to-toe with it, but end up doing what the [[BenevolentPrecursors aliens]] failed to accomplish and actually ''kill'' the Brethren Moon with [[MacGuffin the Machine]].]]
* EyeScream: [[spoiler:Its weak points are its eyes, and it can only be weakened by hurling Markers at them.]]
* FinalBoss: Of ''3''.
* [[spoiler:GeniusLoci[=/=]EldritchAbomination: A representative of an ''entire race'' of them.]]
** [[spoiler:ItCanThink: Presumably. It's certainly smart enough to manipulate people through its own version of Marker visions.]]
* [[spoiler:HiddenInPlainSight]]
* [[spoiler:[[HoistByHisOwnPetard Hoist By Its Own Petard]]: Isaac repeatedly impales it with the very Markers it used to control the Necromorphs.]]
* [[spoiler:MyDeathIsJustTheBeginning: Before its death, it sends out one final signal to reawaken the remaining Brethren Moons. At the end of the DLC, Isaac and Carver arrive at Earth just in time to see that the Moons are already there and are well on their way to devouring the planet.]]
* [[spoiler:SerialEscalation: The single largest boss and Necromorph encountered by far in the entire franchise.]]
* [[spoiler:StarfishAliens: Sapient planetoid aliens, but still. Also the justification for the AbsentAliens trope--the Brother Moons ''ate'' them.]]
* [[spoiler:ThatsNoMoon: Appears to be a broken moon of Tau Volantis.]]
* [[spoiler:UltimateLifeForm: A post-Convergence Necromorph the size of a moon.]]
* WalkingSpoiler
