Crust is a well-built man with dark hair, slicked backwards, a streak of paler hair running down from the centre of his hairline. The back of his right hand seems to be a layer of crust, probably due to his Quirk.
His hero costume consists of a mask over his eyes, and attire similar to the armour Spartans would wear, including a hooded cape and a shirt that appears to be stitched down the middle.
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 has faced with and do his best.
Crust's abilities and Quirk are currently unknown.
