If youbthink thats all there is to saitama, you dont get the character period. Saitamas a joke but hes seen as a joke ss a tragedy of his overwhelming power, he only does right reguardless because he depressed he cant enjoy being a hero, that whole hero for fun **** hasnt been a staple to him since chapter 30. Superman is suppoed to be the fun and bombastic power fantasy but writers just screw that up because they either dont get him or feel jealpus hes set up way better as a enjoyable charscter to fantasize about than batman.
