You could present him as a very "seasoned" chracter; one who's been in enough fights to last one that's a little more off the charts of normal.

I have two new guys who shouldn't be a model at all; one's a hero who's going to be more of an excuse for Calamity or other forces to not smash the group on the spot, and the other's a villain made capable of matching anyone in the group as he is a primary antagonist besides Calamity.
