One Punch Man Season 3 is reported to be coming out in October 2025. The anime was announced to bring the third season this year in the Jump Festa 2025 event. However, the long-awaited third season is in production right now, and it has been already announced that it will be the continuation of the story of the invincible hero Saitama.
This arc is one of the significant ones in the One Punch Man manga narrating the events of the encounter of the Hero Association with the group of dangerous monsters known as Monster Association. By assisting the Monster King Orochi, this group hopes to create some anarchy since heroes who protect humanity are the main targets.
One of the centers of attention in Season 3 will be Garou, a former hero turned villain. Garou who is a former hero who becomes increasingly frustrated with the Hero Association and its imperfections. He becomes an evil “Hero Hunter”, and is dubbed for assaulting and defeating heroes. Gradually, his personality develops, and he is not a completely evil character—Ed identified feelings of compassion and a wish to reform the system of heroes.
As it regards Garou, the play is based on the concepts of morality and heroism as well as the definition of the power of will. He fights heroes and monsters alike making him a key character in this arc.
The fight between the Hero Association and the Monster Association increases to the next level thus causing more injuries. Some of the S-Class heroes that will feature in these fights will include Tatsumaki and Bang. Numerous dramatic fights will be seen as the heroes are to fight progressively powerful opponents – monsters.
Saitama the main character, digitally as well as the physical aspect of the show will also continue to remain a passive spectator to the craziness, mainly because he is a boss of sorts, and no enemy is a match for him. But he can be still involved in the conflict as such, particularly because he has to experience the repercussions of the overwhelming force.
During this season, the protagonist Saitama will remain as unimpressed with anything he faces as before, whereas other characters like Genos, and the rest of the members of the Hero Association will be in some more dangerous situations.
