This character screams grim reaper. In a futuristic, post apocolyptic world you would most definitely find him wondering the streets and chopping heads off. He would either be super quick about it, or he would torture his victim slowly. When he isn't given orders he kills whoever crosses his path, but when the higher ups do give him orders he follows them without fail and very diligently.
