Katsuki Bakugo

Katsuki is a rude, arrogant, short-tempered, and aggressive person, especially early on in the series. Katsuki often appears unkind, a behavior he has carried since childhood, when he bullied Izuku Midoriya, a small, talentless youth who lacked the Force. He displayed excessive arrogance and disdain for others, boasting about the power of his Opening and even boasting that he was ready to fight his entire class. He showed open hostility towards Izuku, primarily due to his former powerless state, and often belittled his dream of becoming a hero despite his lack of the Force, giving him the insulting nickname "Deku" (meaning useless and incapable).

Katsuki is a young man of average height, with a slender, muscular build and fair skin. He has short, spiky sandy-blond hair with jagged bangs that cover his eyebrows. His eyes are bright red and sharp. At school, he wears the standard U.A. uniform, but without the usual red tie. Under his jacket, he wears a white shirt with the top few buttons up. His trousers are worn casually, slipping down at his ankles, though he wears a belt with them. After the war with the Paranormal Liberation Army, Katsuki's school uniform is more polished and now includes a red tie, which he previously didn't wear.

His character's costume consists of a tight, sleeveless black vest with an orange "X" in the middle, creating a V-shaped neckline. On the left collar line are two dots, indicating the company that designed his suit. The suit also features a metal neck guard with rectangular ends and three openings on each side. His sleeves extend from his large, grenade-like bracers to his biceps. His belt, which also holds grenades, holds up his loose trousers with knee pads, under which he wears black, knee-length combat boots with orange soles and eyelets. His mask is patchy and black, with a large orange cutout around his eye.
