Miscellaneous Spin-Off Characters
Dead Space (comic)
- Despair Event Horizon: Its very clear by the time he records his warning log that the hellish events surrounding the colony and its infection have destroyed his will to live. By the end of it he just simply walks away, unarmed and vulnerable, into the derelict, monster-infested halls of the lost colony after giving a final warning not to bother looking for him. Its not hard to imagine his intent, nor his likely fate.
- Noble Bigot with a Badge: 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.
- Only Sane Man: Not quite, but he figured the Marker was bad news as soon as it was dug up.
- Quarantine with Extreme Prejudice: In his final recording, he tells the watcher to order the lost colony nuked off the face of the planet to stop the infection. He eventually gets his wish in a roundabout way thanks to Clarke.
- What Happened to the Mouse?: 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.
Dead Space (mobile)
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 My God, What Have I Done? 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.
- Action Girl: Being female in no way stops her from fighting her way through a spaceborne Zombie Apocalypse. Of course, it's not initially revealed that she's female.
- The Atoner: After causing the Necromorph outbreak on the Sprawl, Vandal works to keep it contained.
- Chainsaw Good: In contrast to Isaac, who was limited to punching Necromorphs, Vandal starts out with a one-handed plasma saw (a chainsaw with an energy blade) for melee attacks.
- Left Hanging: After killing the Boss Necromorph, Vandal suffers serious wounds, and messages Tiedemann, saying they aren't going to make it. Soon afterwards, all that's left is their helmet, and a trail of blood. Whether Vandal escaped, or was turned into a Necromorph is unknown.
- One-Steve Limit: There's nothing to suggest that Karrie Norton is related to Robert Norton.
- Only Known by Their Nickname: Vandal is the codename given to Vandal by Tyler Redikov, Vandal's handler.
- Samus Is a Girl: The shocking twist behind Vandal's true identity in the ending proves that this trope is not dead yet.
- Sanity Slippage: Vandal struggles with this throughout the game.
Dead Space: Martyr
An amorphous necromorph in Dead Space: Martyr.
- The Assimilator: Absorbs everything organic in its path. Its even seen devouring still-living humans and Necromorphs alike.
- Blob Monster: Basically the mobile phase of the Meat Moss found throughout the Ishimura. Think a slime-mold made out if rotting skin cells instead of fungal spores.
- Implacable Man: Only fire has any effect on the creature, and even then the exposure doesnt kill it, only make it back off enough to give Altman and the other survivors some breathing room.
- All Your Powers Combined: It's got a Lurker's whipping tentacles, an Exploder's Action Bomb attack, a Spitter's organic grenades (although it launches skulls instead of tumors), and a Brute's size.
- Captain Ersatz: of one of the monsters from The Thing (1982).
- Multiple Head Case: Possesses several heads instead of one, and they can detach from the main mass and attack prey on their own, like a Divider.
