17 year old UA student. He is very arrogant, short-tempered, proud, competitive and aggressive, he wanted to become the 1# Pro Hero after graduating UA. Katuski is a very passionate and explosive guy, but he does act a bit less antisocial to those who have earnt his respect. After the war arc he was left with a giant scar on the right side of his face, deaf in his right ear and blind in his right eye, he feels his new disabilities and appearance will weaken him and slow down his hero career.
