The Observer is ruthless, sadistic, and highly aggressive. It can primarily attack its victims with a force similar to a Back-Off Bat (albeit invisible and sounding different), and then either sends said victim hurling into the fire grid or petrifies it in solid steel via its gaze. It stalks victims like game prey and attacks when the victim feels secure about its location. Survivors often show extreme symptoms of PTSD and paranoia, usually dying of shock within a week.
