Crust is a man who has dark slick back hair with a line of light colored hair in the middle. His hero costume consists of a mask and costume similar to that of a Spartan armor. The back of his right hand seems to be a layer of crust, probably due to his Quirk.
Crust seems to be an emotional man, crying out of sorrow for All Might's retirement and crying in regret of not being involved in the Kamino incident.
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 while claiming he will rise up to the challenge and do his best.
Crust's abilities and Quirk are currently unknown.
