Marcus Pinzerowski (Pinky)

Marcus Pinzerowski, also known as Pinky, is a technician at the Mars Olduvai Research Facility in the motion picture Doom. He dedicated much of his life to study of the Ark teleporter, and lost his legs during an early experiment with the device when they were teleported to a different, unknown destination than the rest of his body. After this accident, he had a bionic wheelchair grafted to his torso. He is assigned to coordinate the RRTS squad's communications.

Story
Pinky witnesses the death of Dean Portman remotely through Portman's gun cam, but smiles and does not alert the rest of the squad when he sees the attack happen, revealing that he has vengeful and sadistic tendencies.

Pinky becomes involved with the action against his will when monsters emerge from the Ark, invading the facility. He is later found to have transformed into a pinky demon by John Grimm (Reaper) near the end of the film's first-person shooter sequence. Reaper takes on the mutated Pinky using a chainsaw and finally manages to saw the bionic wheelchair off from the rest of his body, killing him.
