A formerly evil robot
Hunter was constructed by Professor van Ness, who used him to abduct people for ransoming and for scientific experimentation. On one assignment, he took a heavy blow to the head which appened to damage his morality processors, turning him good. He returned to Professor van Ness for repairs, then turned him in to the police. He knew that the vanguard had been put under false suspicion (after stalking them for a week and gathering information to put the pieces together), and offered to join them. Omus was highly suspicious, but he was allowed in nonetheless.
