One-Punch Man Wiki

Genos and Memory Loss (ジェノスと記憶喪失, Jenosu to Kiokusōshitsu) is the ninth OVA of the One-Punch Man anime series.


As Genos and Saitama watch TV, Saitama accidentally knocks him out when trying to reach his potato chips and Genos wakes up with memory loss. Genos reads some manga left on the floor in Saitama's apartment, and picks up various character personalities. For example, one personality is childish, talking in a high-pitched voice. Another is a delinquent personality when Genos insults Saitama after discovering Saitama is his master. Later, Fubuki arrives at the apartment and learns that Genos has his memory loss from Saitama. The cyborg hero tries to flirt with her and asks her if she wants to go out with him, Fubuki rejects and takes her leave however. Afterward, upon detecting energy levels via his radar, Genos leaves the apartment and rushes towards something he just detected while expressing surprise as his body is moving by itself. He then faces the Blizzard Group, who wants to recruit him into becoming their comrade. Genos, having his memory loss, however, tries to convince them that they are mistaking him for someone else shortly before running away from them.

Genos later encounters a monster known as the Lord of Mountains. He leads the monster away from civilians as he fights the monster. As his memories have been wiped and he has forgotten how to fight, Genos is beaten down, until the Lord of Mountains shocks Genos with electricity. This gives Genos a memory reboot and he regains his memory. Genos proceeds to fight the monster like normal, easily killing the Lord of Mountains with a single incineration blast. The cyborg hero then returns to Saitama and apologizes for the trouble he has caused.
