ワンパンマン
The seemingly unimpressive Saitama has a rather unique hobby: being a hero. In order to pursue his childhood dream, Saitama relentlessly trained for three years, losing all of his hair in the process. Now, Saitama is so powerful, he can defeat any enemy with just one punch. However, having no one capable of matching his strength has led Saitama to an unexpected problem—he is no longer able to enjoy the thrill of battling and has become quite bored. One day, Saitama catches the attention of 19-y...
Episodes 1 and 2 were previewed at a screening in Saitama city cultural center (small hall) on September 6, 2015. Regular broadcasting began on October 5, 2015. One Punch Man is based on Yusuke Murata's manga remake of ONE's original web comic. The anime adapts the first seven volumes of the manga.
A bored god‑level hero joins a clumsy hero bureau to finally feel a fight’s rush.
Saitama, a bald, unassuming man with a dead‑simple philosophy, spent three years grinding a brutal training regimen that stripped him of his hair and left him invincible. A single blow now shatters any foe, from alien invaders to god‑like monsters, rendering every fight a perfunctory affair. The real tragedy isn’t his power, but the crushing ennui that follows when no opponent can spark a thrill. His quiet life takes a turn when Genos, a teenage cyborg seeking vengeance and a master, witnesses Saitama’s effortless victory and begs to become his disciple. Together they apply to the Hero Association, a bureaucratic league that grades heroes by fame, rank, and paperwork rather than sheer might. Inside the Association, Saitama finally encounters a hierarchy that can actually challenge him—politics, public perception, and rival heroes who wield fame as a weapon. He teams up with an eclectic cast of sidekicks, from a self‑absorbed martial artist to a timid yet earnest rookie, each adding a layer of comedy and camaraderie to his otherwise solitary existence. As the duo tackles increasingly absurd threats, the series balances over‑the‑top action with razor‑sharp satire, poking fun at superhero tropes while delivering genuinely exhilarating battles. Ultimately, One‑Punch Man asks whether true satisfaction comes from being the strongest or from finding purpose amid the chaos of a world that finally notices you.
Saitama’s One‑Punch KO Scenes
Watch the absurdly swift defeats—like the Meteoric Meteor battle in episode 1—where the choreography flips the usual shōnen buildup on its head.
Genos’s Tragic Cyborg Backstory
Genos’s flashbacks reveal a haunting loss that fuels his relentless quest for power, adding emotional weight to the series’ comedy.
Hero Association’s Bureaucratic Satire

Subtle Commentary on Fame and Boredom
Saitama’s existential ennui—highlighted when he’s ignored after saving the city—offers a surprisingly mature take on hero worship.
