Bakugo

Height: approximately 172 cm.

Build: athletic, fit, with well-developed muscles - it is clear that he trains a lot.

Skin: light.

Hair: light, ash-blond, very sticking out in all directions, as if constantly tousled.

Eyes: bright red, with a sharp, "prickly" look.

Facial features: sharp, with pronounced facial expressions - often frowning or baring his teeth.

School Attire: Standard UA uniform (gray jacket with green piping, white shirt, dark green pants), but worn casually - tie loosened or missing.

Hero costume: a black sleeveless top with an orange X-shaped belt on the chest, protective gloves in the form of grenades (they serve as amplifiers for his "explosions"), black pants with orange inserts, protective elbow pads and boots. On the head is a mask with large pointed black and orange "ears" that look like explosions.

If you want, I can describe his facial expression and behavior, because Bakugou's appearance and character come together as a set.

Katsuki Bakugo's character is very bright and memorable - in a good and "explosive" sense:

Hot-tempered and aggressive. He quickly lights up, often shouts and uses harsh words. His anger is not always genuine - often it is just a habitual communication style.

Extremely confident, Bakugo believes he is the best and is willing to prove it.

Ambitious. His goal is to become the #1 hero, surpassing everyone, including Deku (Midoriya).

Hardworking and persistent. Despite his hot temper, he trains a lot and hones his skills.

Straightforward. He says what he thinks without softening, which sometimes offends those around him.

Sensitive to defeats. Bakugou takes his mistakes and weaknesses hard, although he tries to hide it.

Loyal. Although he rarely shows concern openly, he protects his friends and respects those who are strong and honest.

You could say he has an "explosive" temperament, both literally and figuratively, which suits his quirk perfectly.
