Kaz is Batman. He wears dark clothes, is a master of combat, his family is dead, he is a master schemer and incredibly intelligent his archenemy wears colorful clothes like the joker he has allies and he is really cool.
The only thing different about him and Batman is that he is a criminal who kills people. Actually there are 2 differences, sometimes Batman loses, not often, but he does. If Kaz fought Jesus Kratos and Superman he would not even break a sweat.
