I've never seen the TV show, but in the games that I've played, Bomberman sounded a lot like a little girl. I think bombermon should have a slightly deep voice.... like a boy whose voice is in the middle of changing... just without the sqeaking. Know what I mean? I know he's supposed to be sort of chibi but I think the voice that I'm thinking of would fit him.... because it still sounds like a little kid but not REALLY little. He's Bomberman.
