Jack is one of the masked, armed killers who gathered in the desert with Derek. Jack generally moves by himself, one unit, and one alone. He likes his victims demure, yet feisty, and willing to struggle as he exacts his wishes upon them. He mostly hunts down women, with a special attention to smaller women. Jack wears leather clothes, and a bone like dog mask. His hair is cut on the sides, and long on the top. His hair is grey, as are his eyes. He has a patch of stubble on his chin.
