School uniform: He wears the UA Academy uniform with a white shirt, green tie, gray jacket and dark pants, although he usually unbuttons the collar and has a somewhat careless style.

Katsuki Bakugo - Quirk: Explosion
Bakugo's Quirk is called Explosion.
How does it work?
The palms of his hands produce a sweat with properties similar to nitroglycerin. When Bakugo detonates it at will, it generates explosions of varying intensity.
You can use those explosions to:
Attack your enemies.
To propel oneself through the air and move at high speed.
Changing direction in the middle of combat.
Create small, precise explosions or huge detonations.
Featured techniques
AP Shot: Compresses the explosion into a very fine, penetrating shot.
Howitzer Impact: Spins at high speed while building power and unleashes a gigantic explosion.
Stun Grenade: Produces an extremely bright flash accompanied by an explosion to disorient rivals.
Cluster: An evolution of his Quirk that allows him to generate multiple consecutive explosions from different parts of his body, greatly increasing his mobility and offensive power.
Weaknesses
If you use too many large explosions in a short period of time, your arms and hands can suffer, causing pain, fatigue, or even injury.
The cold makes it difficult for his body to produce enough sweat, reducing the effectiveness of his Quirk.
You need to carefully control the amount of sweat and the power of each burst so as not to waste energy.
Hero costume
His enormous grenades on his forearms store the sweat he produces. When he charges them enough, he can unleash explosions far more powerful than normal. Because, apparently, carrying giant explosives on his arms was the most sensible solution they came up with. And, being Bakugo, surprisingly, it works.
