One Punch Man trivia for anyone who has done the 100 push-ups, 100 sit-ups, 100 squats and 10 km run - or at least thought about it. The quiz covers Saitama and Genos, the S-Class heroes from Blast and Tatsumaki to King and Puri-Puri Prisoner, and the villains they face: Vaccine Man, Mosquito Girl, the Deep Sea King, Boros, Garou and the Monster Association. It also goes behind the series: One's original 2009 webcomic and the pun in its Japanese title, how a hospitalised Yusuke Murata came to redraw it, the Madhouse first season and the criticised J.C.Staff second, JAM Project's openings, the voice actors, the games, the Overwatch crossover and the long-gestating live-action film. Difficulty runs from easy questions any anime viewer can answer to expert questions for readers of the manga. Every answer has been checked against a reference page and each question shows its source once you have answered.
