Katsuki Bakugo

Although he isn't the most well-mannered hero, as the story progresses, his behavior slowly begins to mature, becoming less rude and proud. As the year progresses, he begins to trust and cooperate with his classmates, whom he previously rejected because he wanted to do everything on his own, didn't help, and didn't expect to be helped. This egomania led him to make several mistakes in class, leading him to defeat, or very close to it, if not for the fact that he had to reluctantly cooperate with his classmates. His inspiration for becoming a hero was the same as Izuku's, the symbol of peace, All Might. However, their beliefs are different: Katsuki believes that a hero should never stop fighting or give up, regardless of the threat they face, and that always winning is the mark of a true hero.

Katsuki is a young man of average height, with a slim but muscular build and a fair complexion. He has short, spiky, ash-blonde hair with choppy bangs that hang over his eyebrows. His eyes are sharp and bright red.

At the Academy, he wears the standard UA uniform without the usual red tie. Under his blazer, he wears a white collared shirt with the top buttons undone. His pants are loose, causing them to sag at the ankles, even though he's wearing a belt.

His hero suit consists of a tight, black, muscular shirt with an orange "X" in the center, forming a V-neck. There are two dots along the left line of his collar, indicating the support company that designed his costume. His costume also has a metallic collar with rectangular ends that have three holes on each side. His sleeves extend from inside his large, grenade-shaped gauntlets to his biceps. His belt, which also carries grenades, holds up his wide trousers with knee pads, under which he wears black, knee-high combat boots with orange soles and eyelets. His mask is jagged and black, and as it passes around his eyes, a large flare shape with an orange edge protrudes from each side.

His winter hero suit uses a large jacket with a high collar, instead of the usual sleeveless shirt, although it has the same orange "X" design, so he can still sweat a sufficient amount; that's how his Quirk works.

During his internship with Best Jeanist, he wore a pair of blue jeans with his hero costume, instead of his usual baggy pants. His hair was also styled and parted to the side during this tenure.

Katsuki's Quirk allows him to secrete nitroglycerin through his sweaty hands and detonate it at will to create explosions.[6] The more Bakugo sweats, the stronger his explosions become.[7] As stated by Best Jeanist, Katsuki has a strong grasp on the applications of his Quirk.[8] He typically uses small, powerful blasts from his hands to not only blast his opponents, but to propel himself and move through the air as well, among other non-combat uses. He is able to maintain the sequence of his blasts long enough to destroy a giant wall of ice created by Shoto.[9]

The blasts are powerful enough to send opponents flying without much time for them to react.[10] He can use them quickly enough to evade incoming attacks, even in mid-air.[9][11] His most powerful blast yet (without the need for the grenade bracers) was used to completely destroy Ochaco Uraraka's meteor shower, and send her flying away from him with the following shockwave that shook the entire Sports Festival stadium.[12] Though he later uses it multiple times in a row when facing All Might in the final exam's physical test.

Katsuki suffers some impact from his blasts due to their magnitude, but the overall effect is minimal given his physical conditioning. He is able to trigger constant blasts around him without feeling any negative repercussions, even after multiple powerful blasts. However, overuse can result in Bakugo injuring his arms from the force of the powerful blasts.

Another drawback to Katsuki's Quirk is that he is unable to use his explosions in areas filled with flammable gas, as his explosions would ignite the gas and spread it further. This is also because his Quirk relies on his sweaty hands.

General Abilities: Katsuki has proven to be one of the strongest students in Class 1-A, both in his physical and theoretical abilities. Many professional heroes have highlighted his immense skill, including Shota Aizawa himself, All Might, and even the No. 3 Hero, Best Jeanist. The League of Villains has also recognized his strength, sending them to capture him in an attempt to convince him to join them.

Enhanced Strength: Katsuki possesses superior physical strength to the rest of his classmates since he has years of practice and has had fights on par with Izuku when he has used his Quirk or has also known how to pressure and reduce Shoto Todoroki during his battle at the festival. Keen Intellect: Despite having an aggressive and childish nature, Katsuki has proven on many occasions to be intelligent, strategic, and cunning, such as when he managed to discover Kurogiri's weak point and Fumikage's weakness. He also managed to analyze the villains who attacked USJ and determined which of them was the most deadly in the long run. Several professional heroes (including All Might) have acknowledged his strong sense and potential for combat. Shota Aizawa has emphasized that Katsuki's innate talent shines through when he is in battle. Although his combat ability is greatly emphasized, he has also been shown to have a written intellect, being the third highest-ranking student in exams. Leadership Skills: Katsuki has always been criticized for his lack of cooperation, usually as a result of his overwhelming ego preventing him from following the lead of others. However, thanks to Katsuki's determination, perfectionism, and intelligence, he is a capable leader should others choose to follow him.
