Hunter was constantly bullied by his siblings and parents. As a result, he is psychologically stuck in an adolescent state of maturity. Though generally psychopathic, he has some remaining touches of empathy. He enjoys causing others pain and suffering, and displays a pervasive pattern of grandiosity. His parole officer notes that he is disturbed by reminders of how brutal he has become. 

He is one of the story's main psychopaths that Nick must fight at the end of Chapter 1. He is the leader of a biker gang known as the "Kings of Chaos" who causes anarchy in Los Perdidos during the time of the outbreak. He drives a RollerHawg decorated with human parts.

He sees the apocalypse as a welcome change, as it brought the anarchy he desires. He has a deep hatred for the authority and military as he sees them as interfering with him and his gang's "mission". He is the game's first unavoidable psychopath who must be defeated as part of the main story.
