Superalloy Darkshine

Superalloy Darkshine is a formerly S-Class Rank 11 professional hero of the Hero Association who lost his confidence after the battle against the Monster Association, quitting to work as a training instructor and sparring partner for the rival Neo Heroes.

Despite his imposing, hyper-muscular appearance, Superalloy Darkshine is level-headed and genuinely dislikes conflict, often stepping into the role of mediator during S-Class meetings full of egotistical personalities. He's rather vain about his own physique, but that vanity doesn't stop him from respecting fellow heroes like Tatsumaki, King and Genos, or from treating those around him with real kindness. Facing danger, he tends to show an unfazed, blank expression that echoes Saitama's own indifference toward threats most people would find terrifying.
