Katsuki is a young man of above-average height, with a slim, muscular build, and a fair skin tone. He has short, spiky, sandy blond hair with choppy bangs that hang over his eyebrows. His eyes are sharp and bright red in color, he has a very strong personality, he's rude and impolite unlike his culture, with a very big ego making him think that he's the strongest and that he will surpass All Might, calling everyone else that isn't important to him "Extras" or a stupid name based on their looks.
