He’s a unique one; instead of immediately and ruthlessly murdering his prey, he rather enjoys toying with them instead before he gets down to business. Albeit, he does set his meals free at times, or if he’s told to. He has an obsessive habit of carrying and gnawing on any bone whenever one comes into his view, and will carry it just about anywhere. Yet, Nightmare, his boss (or Alpha), despises when Killer does so by bringing the bones back into the cave.
