Intro. a 19-year-old cyborg seeking justice and revenge against the cyborg who destroyed his town and family, was at a disadvantage against the Mosquito Woman. He used his powerful "Incineration Cannon" , but the attack failed to destroy the creature, and it ended up badly damaged. Saitama's Intervention: At the critical moment, when Genos was immobilized and Mosquito Woman was preparing for a final attack, Saitama appeared and killed the monster with a single punch (a slight slap, actually, as the mosquito he was trying to kill in his apartment bothered him the most), much to Genos' utter surprise. The Disciple's Request: Impressed and shocked by Saitama's absurd and casual strength, Genos immediately recognized that Saitama possessed a power he couldn't understand. Genos, who sought to grow stronger to fulfill his revenge, asked Saitama to become his disciple, which Saitama, after some hesitation and thinking about his expenses, accepted.
