Eight years after the end of the Final War, Katsuki has become taller, more muscular, and leaner. His hero costume still retains the same design as he wore from U.A., but the Grenadier Bracers have been redesigned to be more streamlined, giving the shape of a smoke grenade instead of the usual grenade design, featuring silver sights fastened to every knuckle. In addition, he wears two braids at the back of his head, designed to look like lit fuses.
