Bakugo Katsuki

Katsuki's appearance is typical of his character. He has spiky ash-blonde hair that sticks out in different directions, orange eyes that sometimes appear red, and a permanently furrowed brow. In middle school, he wore the standard school uniform, except for the tie. Underneath his jacket he wore a shirt that he never fully buttoned. His pants, despite having a belt, were always loose and baggy.

Katsuki's hero costume consists of a black jumpsuit with orange lines crossed over his chest. He wears black gloves above the elbow, on which he wears special gadgets in battle; black boots with orange inserts, a green belt, and iron kneepads. He also wears an unusual piece of iron jewelry with three holes on each side of his neck. Katsuki wears a black mask and attaches to his head a "spiky" piece of black and orange jewelry that mimics an explosion, similar to his hair. The winter version of the costume features a black turtleneck with a high collar, which also features orange holes.

Blast Wave: the sweat on Katsuki's palms is like nitroglycerin, and he can use it to create explosions.
Katsuki shows masterful control of his quirk
The more Katsuki sweats, the stronger his explosions become. So far, he has used his quirk through his hands, usually boosting his attacks with the explosions created. Katsuki's most powerful blast so far (without using the Grenadier Wristbands) was able to completely destroy Ochako's meteor shower, knocking her down and causing a shockwave that traveled through the stadium[4]. With his extensive combat skills and savvy, Katsuki made the quirk deadly and versatile.

Katsuki suffers no ill effects from his blasts, except for the powerful recoil, which he also resists, though prolonged use of the quirk takes a toll on the muscles and joints of his arms. It is currently unknown if he is susceptible to blasts from any source other than his own Quirk, but during a sports festival he ran straight through buried mines[5] without harm. Among other things, he is able to stay in the air for some time due to the repulsive force of his Quirk.

One disadvantage of Katsuki's quirk is that it is too dangerous to use the quirk in gas-filled rooms. Also, since his quirk relies on increased hand sweating, it is more difficult to use in colder climates because its power will be reduced.

Katsuki Bakugo is a rude, arrogant man who may seem like an anti-hero or even a villain to those who see him for the first time.

Determined and hungry only for victory, Katsuki always smiles intimidatingly during battle. He unwaveringly follows his dreams. Katsuki has had to learn not to underestimate his enemies in order to continue to come out victorious in battles. Despite his temper, he is very talented and intelligent, which is especially evident in moments of battles where he comes up with complex strategies and is extremely sharp with his quirk, using it in more than just direct and brutal attacks. He holds one of the top grades in his class, which also speaks to his high intelligence.
Katsuki doesn't give a damn about the laws on the use of quirks, as he has used them in public many times for intimidation, bragging, or protection
