One-Punch Man #1

This volume kicks off the hit manga series by ONE and Yusuke Murata, introducing Saitama, a hero who can defeat any opponent with a single punch—and is bored by his own overwhelming power. It collects the early chapters of the story, including his first encounters with cyborg Genos and the start of their unlikely partnership. The book sets the tone for the series' blend of action, comedy, and satire of superhero tropes.
