One Punch Man

The One Punch Man watch order runs just 24 TV episodes across two seasons, wrapped around seven short OVAs for the complete Saitama experience. Begin with the Road to Hero OVA, then watch Episodes 1-2 before The Shadow That Snuck Up Too Close OVA. The pattern continues through Season 1: The Pupil Who is an Extremely Poor Talker slots in after Episode 4, The Ninja Who is Too Complicated after Episode 7, and Episodes 8-12 close the first cour. Three more OVAs — The Sisters Who have Too Many Things Happening, Bang Who is Too Overbearing, and The Murder Case That is Too Impossible — bridge the gap before Season 2's Episodes 13-24. If you only want the main story, the OVAs are skippable side pieces, but this is the correct order to watch everything with each extra in place.
