One-Punch Man is an anime series that packs a serious punch with almost no filler. It follows the exploits of Saitama, a powerful hero who can defeat almost any adversary with a single punch.

The first season of the anime version of One-Punch Man follows closely to the manga series. But what makes One-Punch Man unique is that the manga itself is actually based on a web comic. The manga improves upon the art work and style of the web comic, while also making the tone of the story more serious in nature – which the anime series draws most of its material from.
