Jack is a very likable guy. He is very good at keeping everything nice and tidy. He is quite strong and can be quite protective over the people he has grown to like. During night time, when nobody is there, he hangs out with his "gang". They are ruthless criminals and none of them is afraid to hurt or even kill if thats what the situation requires. His skin and fur are resistant to fire, due to a genetic experiment that was conducted on him as he was a child.
