Background / History

Genos's village was massacred and his parents were killed by cyborgs sent by Metal Knight Bofoi. The event drives his pursuit of cyborg-related threats and his eventual confrontation with Bofoi. Dr. Kusuno rebuilt him as a powerful cyborg and became the closest thing Genos has to family besides Saitama. 68 152

After fighting Mosquito Girl in Z City, Genos seeks out Saitama and sincerely requests to become his disciple. Saitama tells him to join the Hero Association first; Genos accepts immediately and commits himself to meeting his teacher's expectations. 14 15

Personality
