Thomas Murphy is a prisoner who resided in the correctional unit on Fiorina 161 and the caretaker of Spike.


He spent most of his early life on the run from the law. A conversation between Frank and him implies that he has been sentenced to prison for sexual deviance and probably abuse as well. He appears to have a shorter prison sentence than most and often volunteers to help in efforts (like finding survivors from the EEV) in attempts to shave a few months off of his sentence. He is first introduced searching the EEV for survivors with his dog, Spike, and later mourns over his corpse after the alien emerges from it (though he thinks a human did it). Later, he is seen cleaning the giant air ducts of the prison. He steps on the aliens shed skin and is clearly disgusted by his find. He hears noises coming from a hole in the wall, and goes to investigate, believing it to be his dog, Spike. He soon realizes it is not his pet pooch but a juvenile Alien. Before he can pull his head out of the hole, the alien spits acid into his face. He stammers backwards in agony and accidentally tumbles into a large spinning fan, killing him instantaneously.


  • The song Murphy sings while cleaning the vent shafts is "In the Year 2525" by Zager & Evans. In the comic adaptaion, Murphy sings "Paint it Black" by the Rolling Stones.
