Bakugo Katsuki

Spiky ash-blonde hair sticking out in all directions.
Orange eyes, sometimes appearing red.
Constantly furrowed brows.
Slender muscular build, fair skin.
The hero costume consists of a black jumpsuit with orange lines crisscrossing the chest, black elbow-length gloves, black boots with orange accents, a green belt, and iron kneepads. He also wears a black mask and a spiky black-and-orange headpiece that mimics an explosion.

Quirk. The power of Katsuki's Quirk depends on how much he sweats—the more he sweats, the more powerful the explosions. However, prolonged use of the Quirk can negatively impact the muscles and joints of his arms.
Values. Katsuki values ​​hard work and fair play. He may refuse to acknowledge a victory if he believes it wasn't truly earned.

Main character traits
Rudeness and arrogance. Katsuki can seem like an antihero or even a villain to those meeting him for the first time. He speaks crudely, doesn't call his classmates by their names, and uses nicknames based on their appearance. His self-confidence was fueled by excessive praise from others, which created a superiority complex.
Aggressive and impulsive. Katsuki is prone to arguments, quarrels, and is picky and contradictory. He quickly finds arguments and always defends his point of view, confident in his rightness. In battle or when defeated, he can lose his composure.
Determination and a thirst for victory. Katsuki unwaveringly pursues his dream of becoming the strongest hero. He competes fiercely and will never settle for anything less than first place.
Talent and intelligence. Despite his rude nature, Katsuki is talented and intelligent. He develops complex strategies in battle, is quick with his Quirk (a blast wave that ignites sweat similar to nitroglycerin), and holds one of the highest academic standings in his class.
Insightful and able to discern people's worth. Katsuki is able to discern lies.
Emotional instability. He is characterized by sudden mood swings and nervousness. He can be irritable and picky if he is dissatisfied with something.
Character development
After entering U.A. Academy, Katsuki's personality began to change. Turning points in his life, such as his first loss during the "Trial by Battle" against Izuku, forced him to view life differently. However, some of his rudeness and arrogance remained.
