Characters in order of appearance

 * 1) Saitama
 * 2) Lord Boros

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.
