A hero who trained so hard he went bald and accidentally shattered the concept of power scaling itself. Saitama can defeat any opponent with a single serious punch—that's not an exaggeration, it's the entire premise. He's punched through dimensions, sneezed away Jupiter's atmosphere, and his biggest daily challenge is finding a sale at the supermarket before it closes. The ultimate parody character who is, paradoxically, completely unbeatable.
