One-Punch Man season 3: release date, new trailer, and everything we know so far

After years of waiting, One-Punch Man season 3 has been narrowed down to a single month.

Below, we'll run through that release date window, as well as what else is to come as the series adapts the Monster Association arc. There's even a new trailer to get stuck into.

From what we've seen so far, there's plenty to suggest the new anime could be among this year's leading lights. While we wait for further news, we've put together a cheat sheet for One-Punch Man season 3, including a look at the manga chapters it could adapt in the upcoming season, as well as the confirmed cast list.

One-Punch Man season 3 release date speculation

One-Punch Man season 3 is releasing in October 2025.

Given that most fall releases drop in the first week of October, we'd expect One-Punch Man to follow suit.

Either way, it's been a long time in coming. The first season debuted way back in 2015, while the second season aired in 2019. In other words, we’ve spent over half-a-decade waiting for the One-Punch Man season 3 release date to surface. Now, we're only months away from Saitama's return.

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

One-Punch Man season 3 will continue 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.

A season of One-Punch Man typically covers around 40-50 chapters of the source material. If that’s the case again, we could expect this season to end around chapter 123 – and the debut of a character known as Psykos (to say any more would be a significant spoiler…)

Until then, expect the perpetually bored Saitama to continue fighting monsters alongside his fellow heroes and Garou to spend more time with the Monster Association as an all-out war ensues. Society’s reaction to the monsters differs, with one splinter group – The Monster Worship Party – submitting themselves to the monsters.
