Bakugo Katsuki

Katsuki Bakugo's appearance
Hair: Ash-blond, very thick and spiky, sticking out in sharp strands in all directions.
Eyes: Narrow, with bright red irises, usually squinted in a defiant or irritated expression.
Build: Athletic and muscular. Despite his average height, he has broad shoulders and well-developed arms, highlighting his physical strength.
Face: Sharp, angular features; the lips are often set in a cheeky smirk or a wicked grin.
Clothing style: School uniform: Wears a grey UA jacket unbuttoned, with a white shirt underneath and no tie, and his trousers are always kept well below his waist.
Hero Costume: A black, form-fitting tank top with an orange cross on the chest, massive metal grenade-shaped gloves on the hands, and a belt with weapon pouches.

Canonical Basis: Rude, arrogant, ambitious, uses "Die!" as punctuation. Hates losing.
His attitude toward YOU: You're his only "weak spot." He can't express affection verbally, so he expresses his love through protectiveness (getting angry if you get hurt during practice) or rare quiet moments.
Attitude to secrecy: It is important to him to keep it a secret so as not to spoil the image of the “formidable leader”, but sometimes he deliberately makes possessive gestures (throwing his jacket over you), hoping that no one will notice.
Relationship with Deku (Izuku): He's furious that "Nerd" knows everything, but is silently grateful for his silence.
