The series was licensed by Viz Media in North America, who produced an English-language dub.

On October 15, 2016, the series was moved to 3:00 AM and was re-aired from the first episode, until it finished its run on January 28, 2017, and was replaced in the lineup by Ghost in the Shell: Stand Alone Complex the following week. Reruns of season 1 returned to Toonami on August 11, 2018 at 2:30 AM and concluded on November 3, 2018. The series is rated TV-14-LV on Adult Swim.
In May of 2018, Viz Media announced that it has acquired the master license for One-Punch Man Season 2, including TV broadcast, digital streaming, electronic sell-through, home media, and merchandising rights for North America, Latin America and Oceania. The second season of One Punch Man premiered on Toonami on October 12, 2019 at 11:30 PM. On January 4, 2020, the series moved from the 11:30 PM time slot to the 12:00 AM time slot.

The story takes place in the fictional Japanese metropolis of City Z. The world is full of strange monsters that mysteriously appear and cause disasters. Saitama, the protagonist of the series, is the strongest hero, who easily defeats the monsters or other villains with a single punch. However, due to his immeasurable strength, Saitama has become bored with his power and is constantly trying to find stronger opponents who can present a challenge to him. As Saitama is active as a hero, he meets various other heroes and villains. He gets a disciple, the cyborg Genos, and consequently joins the Heroes Association in order to gain official recognition. Despite defeating many strong monsters that even the Heroes Association’s top members are unable to defeat, Saitama struggles to gain respect. Most people look down on him due to his plain physical appearance, and some accuse him of being a counterfeit hero. Only a small number of individuals in the series recognize his talent and humility towards others.
Saitama — The protagonist of the story, Saitama, is a powerful hero with superhuman strength, speed, and endurance, along with near complete invulnerability. Though his powers are limited to improvements on typical human traits (e.g., he cannot fly or project energy), his physical capabilities are so preposterously advanced that no enemy has ever inflicted serious damage to him. By contrast, his strength is so immense that most of his targets fall to a single punch, killing them, hence the title of the series.
Genos — Genos is a cyborg who decided to become Saitama's disciple after bearing witness to Saitama's easy victory over Mosquito Girl. While Saitama was adamantly against his decision, he accepted after Genos suggested paying part of his rent. Genos tells Saitama about the Hero Association when he hears Saitama's complaints about not being recognized despite his actions, and they both decide to take the official hero exam and become registered super heroes. Genos is often overzealous and defensive when Saitama is not recognized by the other heroes for his feats, despite Saitama himself not really caring. Genos is a very serious character, and is constantly annoying Saitama to teach him how to become stronger.
