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 foe after growing bored by a lack of challenge in his fight against evil. ONE wrote the original webcomic version in early 2009, and it quickly grew in popularity, surpassing 7.9 million hits in June 2012. The series has since received a manga adaptation illustrated by Yusuke Murata, as well as an anime adaptation.
