Alongside the date, the production team unveiled a teaser visual and confirmed the new staff leading the adaptation.
Story Synopsis
Based on ONE’s original webcomic and Yusuke Murata’s popular manga remake, One-Punch Man follows Saitama, a hero who can defeat any opponent with a single punch. While his overwhelming strength leaves him bored and often overlooked by society, his presence continues to reshape the Hero Association and challenge monsters threatening humanity.
Season 3 is set to adapt the Monster Association Arc, one of the manga’s most intense storylines. Fans can expect escalating clashes between S-Class heroes and the monstrous villains, culminating in Saitama stepping into conflicts that test even his unmatched strength.

- One-Punch Man began as a self-published webcomic by creator ONE in 2009 before Murata’s illustrated version in Young Jump Web Comics propelled it to global fame.
- The anime’s first season (2015), produced by Madhouse, is widely considered one of the best animated shonen debuts of the decade.
- Season 2 (2019), handled by J.C. Staff, received mixed reviews for pacing and visuals, making Season 3 a highly anticipated chance at redemption.
- The Monster Association Arc in the manga spans over 80 chapters, meaning Season 3 could become the most action-packed installment yet.
