The highly anticipated third season of the beloved anime series One-Punch Man officially premiered on October 12, 2025, with a recap special of Season 2 airing a week prior on October 5. After years of anticipation, fans can now dive back into the action-packed world of Saitama and the Hero Association as the series adapts the thrilling Monster Association Arc from Yusuke Murata’s manga.
Release Details and Where to Watch
One-Punch Man Season 3 began its broadcast in Japan on TV Tokyo and other networks, with new episodes releasing weekly every Sunday. For international viewers, the season is available on various streaming platforms. In the United States, fans can stream new episodes on Hulu, while Canadian viewers can find it on Disney+. Crunchyroll is carrying the series in Europe, the Middle East, and parts of Asia, as well as Latin America and Oceania. Netflix has also confirmed streaming in Latin America, Australia, and New Zealand, with the original Japanese audio available.
The Monster Association Arc Unfolds
Season 3 picks up directly after the events of Season 2, thrusting viewers into the full-scale conflict of the Monster Association Arc. This arc, one of the most intense and pivotal storylines from the manga, sees the Hero Association facing its gravest threat yet as a formidable coalition of monstrous beings, led by Orochi and Gyoro Gyoro, declares an all-out war on humanity.
Key Storylines and Character Focus
While Saitama continues his comically relatable struggle against boredom and his search for a worthy opponent, the season will delve deeper into the complex transformation of Garou, the “Hero Hunter.” Garou’s evolution blurs the lines between man and monster, making him a central anti-hero whose journey challenges conventional notions of power and justice. The S-Class heroes will be pushed to their limits as they embark on a high-stakes mission to rescue a hostage and confront the Monster Association in their secret hideout.
The initial episodes of Season 3 set the stage for this epic conflict, balancing explosive action with the series’ signature humor. Episode 1, while serving partly as a recap, effectively reintroduces the escalating chaos and Saitama’s detached demeanor. Episode 2, titled “The Hunt Begins,” is expected to intensify the action as heroes prepare for battle and Garou’s role becomes increasingly prominent.
Production Details and Animation Discussion
J.C. Staff, the studio responsible for Season 2, returns to animate One-Punch Man Season 3. Shinpei Nagai takes over as director for this season, with Tomohiro Suzuki handling series composition and Sakura Murakami as art director. The main voice cast, including Makoto Furukawa as Saitama and Kaito Ishikawa as Genos, are reprising their roles. English dubbing is also expected to follow the Japanese release.
The transition of animation studios from Madhouse (Season 1) to J.C. Staff for Season 2 had previously drawn criticism from some fans regarding a perceived drop in animation quality. With Season 3’s premiere, discussions around the animation quality have resurfaced. However, animators like Vincent Chansard (known for One Piece) have defended J.C. Staff, stating that animation production issues are often more complex and involve the broader production committee and challenging industry conditions, rather than solely the animation studio’s fault.
Episode Count and Future Outlook
One-Punch Man Season 3 is officially confirmed to consist of 12 episodes, maintaining the same structure as its predecessors. New episodes will be released weekly, leading up to the season finale around late December 2025. The season promises to deliver a blend of jaw-dropping action, sharp humor, and deeper exploration of the story’s philosophical themes of power, purpose, and identity.
