Someone tried to ask the stupid question of "Are those real?", and the Punching-Bag looked like he was wanting to touch them. So Satoshi kicked that thing and fired a blast of energy with his foot, since he has only one arm and he's using it to cover his boi-boobs. How'd he lose his arm? *shrugs* But he seems to be doing well with one arm. Kinda like Future Gohan, one of the Top 5 most badass DBZ characters.
