One-Punch Man season 3, part 2 release date speculation

One-Punch Man season 3, part 2 is releasing in 2027, with the first part airing from October 2025-December 2025.

One-Punch Man season 3 story: which manga chapters will it adapt?

One-Punch Man season 3 continues the Monster Association arc from Yusuke Marata's manga, which sees the Monster Association arrive at the Hero Association with a message about wanting monsters and heroes to co-exist – something which quickly turns around to be a ruse.

Instead, the Monster Association wants an all-out war between heroes and monsters, led by Orochi and Gyoro. Also in season 2, hero hunter Garou is confronted by various heroes wanting to prove their worth to the Hero Association – including Death Gatling. It leads to a fight between Saitama's protege Genos and Garou, with the latter being saved by the Monster Association's Phoenix Man.

Inevitably, Saitama – having been sidetracked by attempting to best King at video games – comes and saves the day. He kills the monster Elder Centipede and remarks that a despondent Genos needs "power" to improve as a hero.

So, that's where we're at. What's next for One-Punch Man season 3? If you're following along in the manga, we're starting from chapter 86. For part 2, we're up to chapter 117.
