After years of waiting, Saitama is finally returning to our screens. One-Punch Man Season 3 is officially on the way, bringing with it the long-anticipated Monster Association arc. Here’s everything you need to know — from release date and trailer details to streaming platforms and what to expect from the story.
One-Punch Man Season 3 drops on October 5, 2025, but reports suggest the premiere may start with a recap episode, with new episodes beginning on October 12.
It’s been a long wait. The anime first premiered in 2015, followed by Season 2 in 2019. Now, after more than six years, fans are only weeks away from returning to the world of heroes and monsters.
Series creator ONE expressed his excitement:
“I am truly looking forward to the broadcast of One-Punch Man Season 3. We wouldn’t have been able to come this far without our fans. Season 3 will go deeper into the new adventures of the S-Class heroes.” – ONE (via ScreenRant)
A new 15-second teaser has dropped, giving fans their first real look at what’s to come. While short, it teases glimpses of high-stakes battles and sets the tone for the Monster Association arc.
The trailer also revealed the anime’s new themes:
The promo has fans hyped, but some are cautious about the animation quality — especially after the criticism of Season 2. Still, the anticipation for Saitama’s return is stronger than ever.
Like the first two seasons, One-Punch Man Season 3 will stream on Crunchyroll, though currently confirmed only for the UK, Ireland, and Europe.
For fans in the U.S., the series is expected to stream on Hulu, but official confirmation is still pending.
Meanwhile, Viz Media has secured streaming rights for North America, Latin America, and Oceania, with further details to be announced soon.

Season 3 will adapt the highly anticipated Monster Association arc from the manga. This storyline picks up where Season 2 left off, diving deeper into the war between the Hero Association’s strongest fighters and the Monster Association.
Fans can expect:
Framed around the theme of “Strongest vs. Scariest,” this arc promises some of the most intense battles in the series so far, while still keeping the satirical humor that One-Punch Man is famous for.
After a six-year hiatus, One-Punch Man Season 3 is finally within reach. With its October 5 premiere date, a new trailer, and the Monster Association arc on the horizon, fans have plenty to be excited about.
While concerns about animation quality linger, the return of Saitama and the Hero Association guarantees big moments, shocking battles, and the deadpan humor that made the anime a global hit.
Whether you’re tuning in via Crunchyroll, Hulu, or Viz Media, one thing’s certain — Saitama is back, and the wait has been worth it.
