Crust is a well-built man with black hair slicked backwards, with a streak of white hair running down from the center of his hairline. The back of his right hand seems to have a layer of crust, probably due to his Quirk.
His hero costume consists of a black mask over his eyes, and attire similar to the armor Spartans would wear, including a green hooded cape and a black shirt that appears to be stitched down the middle with a red pattern.
He is introduced during the announcing of the top hero rankings of the year's second semester. He cries over All Might's retirement and his absence during the Kamino Incident, and claims that he will rise up to any challenge he's faced with and do his best.
Overall Abilities: Crust's abilities are currently unknown, however, his being among the top ten in the Hero rankings suggests that he is a highly capable Hero. Given his epithet of Shield Hero, he presumably specializes in defense.
