Saitama was not a complicated man. When he found himself walking down the streets of an unfamiliar city in an unfamiliar world he decided to just roll with the punches. Becoming part of a Troupe of criminals was entertaining as anything else, and being a Hero just got boring after a while. If there's one thing he learned from comic books...bald people make great antagonists.

With a flash of lightning, Saitama's entire world is turned upside down. Forced into a realm that is completely off its hinges, it appears to be the responsibility of one bald hero to deal with a world with a freakishly optimistic kid, a child assassin, a rather sketchy magician, a vengeful teen, and some weird guy who looks old...but is a teen? UP FOR ADOPTION! DISCONTINUED!

Leorio, being the kind person that he is, will always want to heal others. Even if he can be a bit to brash sometimes. So, being a hero, while not something he saw himself as, is something he is willing to do to prevent these new friends from dying.

"I'm just here for fun," the bald man said, as though he was saying that the sky was blue or the grass was green. Hisoka was intrigued.
