Big things are happening on TV Tropes! New admins, new designs, fewer ads, mobile versions, beta testing opportunities, thematic discovery engine, fun trope tools and toys, and much more - Learn how to help here and discuss here.
Offscreen Villainy: His past crimes are discussed, but by the time of the story he seems past all of that.
Rape Is a Special Kind of Evil: Despite being a past rapist and murderer himself, he considers it a serious breach of the prisoners' philosophy to do so anymore. He saves Ripley from a rape attempt by the other convicts and bashes them with a crowbar to do some 're-educating'.
Nice Job Breaking It, Hero: in the Assembly Cut, the prisoners actually did manage to trap the alien. Unfortunately Golic, who worships the thing as a kind of dragon, kills the guard and lets it out again. Oops.
Psychopathic Manchild: He's easily excited, easily upset, and apologizes frantically to his murder victim like a misbehaving child.
Talkative Loon: Halfway. He doesn't say a lot, but when he does speak, he tends to babble.
Noodle Incident: When collecting chemical barrels with Ripley, he mentions witnessing the chemical's explosive properties firsthand. He doesn't go into much detail, but the blast was big enough to put a ship in dry dock for 17 weeks.
Robotic Reveal: Averted. While he tells the other people he's human, Aaron hits him in the head calling him a robot...causing him to bleed red. Strangely enough, he doesn't bleed ostensibly from the wound (with an ear hanging off, nothing less) nor looks dazed after receiving a smack that would have quite possibly killed a human of his physique, so many fans believe that he could be an android after all. In the Assembly Cut, he has a much more noticeable reaction.
