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's one of the One Punch Man characters that wasn't mean-spirted to Saitama.
