One-Punch Man Season 3

Following the Monster Association’s abduction of a Hero Association executive’s son, the S-Class heroes assemble for a coordinated assault on the monsters’ underground headquarters. While Saitama remains largely removed from the operation’s planning, Genos, Tatsumaki, Child Emperor, and their fellow heroes prepare to confront an organization containing numerous Dragon-level threats.

Inside the stronghold, Garou continues his violent evolution while attempting to escape the monsters who captured him. The first part of the season adapts the opening stages of the Monster Association raid, dividing its attention among Garou, the S-Class strike force, and the lower-ranked heroes fighting above ground. It ends partway through the larger arc, with a second part announced for 2027.
