Genos (One Punch Man)

Genos, or the Demon Cyborg, is the deuteragonist of the webcomic-turned manga/anime series One Punch Man. He's an S-Class hero of the Hero Association and is the disciple of Saitama, as he seeks to become stronger to kill a rogue cyborg that killed his parents four years ago. He acts as a foil to Saitama in the series.

Why He Rocks

 * 1) His character design is overall the best design out of all the One Punch Man characters thanks to his cyborg body.
 * 2) He along with Tatsumaki, Fang, Mumen Rider, etc are the One Punch Man characters that wasn't mean-spirted to Saitama.
 * 3) His backstory in the second episode of the One Punch Man show was emotional as it shows that he was originally a human but then got turned into a cyborg after his city was destoryed and he almost died until Saitama punched the Mosquito Girl.

Bad Qualities

 * 1) He once infamously annoyed Saitama in the second episode by calling him "sensi" and "master" a lot and infamously bald shamed him in the same episode.
