A superhero with no super powers or abilities, he is just a regular guy who gets into a lot of trouble. He doesn't fight crime, crime fights him. He isn't exactly the sharpest tool in the shed, but he always manages to somehow save the world, at the expense of (accidentally) destroying the majority of whatever it is he is trying to save. Overall Fightman is just a nice guy, who has a nasty habit of blowing up things (unintentionally).
Fightman doesn't look for trouble- he trips on it.
