The iconic Japanese rock band JAM Project will return to fuel One-Punch Man Season 3 with a dynamic opening theme, as announced by the official One-Punch Man X account. This marks the band’s third contribution to the beloved superhero anime, following their unforgettable tracks for the first two seasons. Their return promises to amplify the energy of Saitama’s latest adventures, set to premiere in October 2025 under the direction of J.C.Staff.
JAM Project first captured the essence of One-Punch Man with The Hero!! ~Ikareru Ken ni Honō o Tsukero~ for Season 1, a high-octane anthem that perfectly matched Saitama’s invincible yet comical persona. They followed with Uncrowned Greatest Hero for Season 2, blending intensity with emotional resonance to reflect the series’ growing complexity. While the title of the new opening theme remains undisclosed, JAM Project’s signature style is expected to complement the escalating stakes of the Monster Association arc, delivering a song that captures the series’ unique mix of humor, action, and introspection.
Since its origins as ONE’s webcomic in 2009, One-Punch Man has evolved into a global sensation, with Yusuke Murata’s detailed manga and the anime adaptation drawing widespread acclaim. The story of Saitama, a hero who defeats any opponent with a single punch, continues to resonate for its sharp satire of superhero tropes and its exploration of purpose amid unmatched strength. JAM Project’s return underscores the series’ commitment to delivering a bold, memorable experience in its third season.
What to Expect in One-Punch Man Season 3
One-Punch Man Season 3 will dive deeper into the Monster Association arc, a pivotal storyline from the manga that pits the Hero Association against a formidable coalition of monsters wreaking havoc in City Z. Viewers can anticipate Saitama and his disciple Genos confronting new threats, including the rise of Garou, the self-proclaimed “Hero Hunter” whose crusade against heroes intensifies. The season will likely center on the fallout from the seer Shibabawa’s prophecy of a catastrophic threat, with key events like the kidnapping of a Hero Association executive’s son and a massive assault on the monsters’ stronghold.
The narrative will balance explosive battles with deeper themes of heroism and identity. Saitama’s ongoing struggle with boredom and his search for a worthy opponent will remain at the core, while characters like Garou and the mysterious top-ranked hero Blast introduce new layers of intrigue. J.C.Staff’s animation is expected to elevate the manga’s intense visuals, bringing the chaotic battles and Saitama’s deadpan humor to life.
With JAM Project’s opening theme setting the tone, One-Punch Man Season 3, premiering in October 2025, promises to deliver a captivating blend of action, comedy, and existential wit that fans have come to love.
