Bakugou is a man of 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’s a crude, arrogant, short-tempered, and aggressive person. Determined and thirsty for victory, Katsuki’s goal is to be the #1 pro hero. He also possesses surprising talent in other areas, such as cooking and music, even though he doesn't show a particular interest in them.
