The story of Saitama, a hero that does it just for fun & can defeat his enemies with a single punch.
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.
In a world of superhuman beings, Saitama is a unique hero, he can defeat enemies with a single punch. But being just one hero in a world filled with them, his life is empty and hollow: he gets no respect from anyone, he displays a laidback attitude to everything and for the most part, he finds his overall hero life pointless… and worst of all, he lost his hair due to intense training. These are the adventures of an ordinary yet extraordinary hero.
