Hard Head is an extremely tall, well-built man with extremely large arms. Fitting to his name, he wears a helmet that completely encases his head barring a slit for his eyes. He also wears a black tank top, greenish-brown trousers and brown shoes.
Not much is known about his personality. Given he is one of the many villains willing to challenge the staff at U.A. High School, he can be assumed to be quite confident in his abilities.
Hard Head was one of several villains who ambushed Denki Kaminari, Kyoka Jiro, and Momo Yaoyorozu in the Mountain Zone of the Unforeseen Simulation Joint. Hard Head attacked Denki while he was complaining about his Quirk not being effective, but Kyoka kicked Denki into Hard Head. Denki reflexively activated Electrification, incapacitating Hard Head. Hard Head was later arrested when the U.A. teachers arrived.
