One-Punch Man

One-Punch Man (Japanese: ワンパンマン, Hepburn: Wanpanman) is an ongoing Japanese webcomic created by an author using the pseudonym One, which began publication in early 2009. The series quickly went viral, surpassing 7.9 million hits in June 2012. The Japanese shortened name Wanpanman is a play on the long-running children's character Anpanman (the form pan (パン^?) is not a standard abbreviation for punch (パンチ, panchi)).

A digital manga remake of the series, illustrated by Yusuke Murata, began publication on Shueisha's Young Jump Web Comics website in 2012. Viz Media has licensed the remake for English serialization in its Weekly Shonen Jump digital magazine. A television anime adaptation by Madhouse aired in Japan between October and December 2015.
