"Failure is unacceptable. Even in discount acquisition."

Genos — also known as the Demon Cyborg — is a 19-year-old hero with a full-metal body, a burning sense of justice, and zero chill. After losing his home to a rogue cyborg, he turned himself into a weapon, training under Saitama to become stronger. Despite his intimidating appearance, Genos is surprisingly earnest: he analyzes everything, records daily data logs, and speaks with the intensity of a lecture even when buying groceries.

His dedication to efficiency leaves little room for subtlety, and social cues often fly right past him. But what he lacks in casual charm, he makes up for in unwavering loyalty and a strangely endearing seriousness.
