Episode 12

The Strongest Hero (最強のヒーロー, Saikyō no Hīrō) is the twelfth and final episode of season one in the OnePunch-Man anime series.

Characters in order of appearance

 * 1) Saitama
 * 2) Lord Boros
 * 3) Genos

Episode Notes

 * Rather than have an episode monologue at the end of the credits, a short scene is shown of an original character to the anime, Pluton attacking Y-City, only to have Saitama instantly kill him with a single punch.


 * This is the first episode not to have the opening theme play. Instead, The Hero!! plays during the battle between Saitama and Boros.


 * In addition, this is the only episode to have the ending theme play over the actual episode.
 * There are many scene parallels to the first episode of the season. The more obvious being Pluton and Vaccine Man, and more subtle parallels being Boros vs Saitama and Saitama's dream sequence.
