Crust was a well-built man with black hair combed backward, with a streak of grayish-white hair running down from the center of his hairline. The back of his right hand had a layer of crust, probably due to his Quirk.
His hero costume consisted 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.
Crust was a very emotional man, crying out of sorrow for All Might's retirement and crying in regret for not being involved in the Kamino Incident. He was also very noble, sacrificing himself to save Shota Aizawa from Shigaraki's Decay at the cost of his own life, flashing an encouraging thumbs up and grin as he disintegrated, showing he didn't regret his decision.
Overall Abilities: Crust was a highly capable hero who earned his spot in the top 10 heroes in all of Japan. Deserving of his No. 6 ranking, Crust was a talented fighter who specialized in using his Quirk on a team with others. He had enough strength and fighting capability to fight against several Nomu, including Four High-Ends. Thanks to Crust's proficiency in team battles, he was able to act as the center of the Hospital Raid Team's efforts against the High-Ends.
