One-Punch Man (Japanese: ワンパンマン, Hepburn: Wanpanman) is a Japanese superhero franchise created by the artist ONE. It tells the story of Saitama, a superhero who can defeat any opponent with a single punch but seeks to find a worthy opponent after growing bored by a lack of challenge due to his overwhelming strength.
Life gets pretty boring when you can beat the snot out of any villain with just one punch.
