After a long wait, One-Punch Man Season 3 finally arrived — adapting the manga's biggest arc yet. But its reception was anything but smooth. Here is everything to know.

Quick answer Season 3's first cours aired from October to December 2025 (J.C. Staff), adapting the Monster Association arc and Garou's rise. It drew heavy criticism for its animation, and a second cours is set for 2027.

The release

One-Punch Man Season 3's first part aired from October 12 to December 29, 2025, with a recap special the week before. A second cours was announced immediately afterward and is scheduled for 2027, splitting the season into two parts.

The story: the Monster Association arc

Season 3 adapts the long-awaited Monster Association arc, in which the Hero Association mobilises its strongest S-class heroes against an organised army of monsters. At its center is Garou — the self-styled "Hero Hunter" whose journey is one of the manga's most compelling threads, voiced once again by Hikaru Midorikawa.

The backlash

Expectations were sky-high, and the production struggled to meet them. Under J.C. Staff, with a new directorial team, Season 3 drew overwhelmingly negative reviews — Anime News Network even named it among the worst anime of 2025 — with fans pointing to limited animation and static shots in a series famous for its spectacular fights. It became a cautionary tale about how much a beloved action anime lives or dies on its animation.

Key takeaways

  • Season 3 adapts the Monster Association arc and Garou's rise.
  • The first cours aired late 2025; Part 2 is set for 2027.
  • Its animation drew heavy criticism, a low point for the franchise.
