Katsuki bakugo

Katsuki was presented as a very impulsive, aggressive and arrogant person, as seen in his treatment of Izuku, whom he constantly violated physically and psychologically. He has a superiority complex, always wanting to be the best at everything and trying to prove it at all costs; However, even with these traits, he knows how to admit well when he has been defeated, as demonstrated during the Battle Test, when at the entrance of the academy, Izuku tried to explain to him that his Quirk One For All came from someone else, and Katsuki interpreted that he was making fun of him, so he tried to shut him up by saying that he simply beat him. In battle, he tends to be quite bloodthirsty and aggressive, even to the point of turning the word "shine" into a crutch. His brutal fighting style is shown in the Battle Test, in which he mercilessly attacks Izuku and carelessly destroys everything in the enclosed environment in which they found themselves. Despite this and regardless of his lack of compassion, he has been recognized as having enormous talent and sharpness in combat, since he not only attacks and destroys, he is also capable of using his Gift to move in the air.
Although he is not the most well-tempered hero, as the story progresses his behavior slowly begins to mature, becoming less rude and prideful. Katsuki feels that a hero should never stop fighting or giving up, regardless of the threat they face, and that winning is always the mark of a true hero. Furthermore, due to his arrogant and boastful behavior, several heroes, civilians, and even villains have commented on his behavior as more villainous than heroic. However, Katsuki is unwavering in his goal of becoming a hero. At first, when he is defeated, he goes into a kind of shock, and on top of this, he does not admit that he surpasses others when the fight ends without him landing the finishing blow, such as when he fought Ochaco Uraraka at the Sports Festival.

During cold weather, sweat-nitroglycerin takes a slightly longer time to ignite, as opposed to warm weather, where conditions are optimal for ignition.

As the Quirk has proven to be powerful and possibly fatal with the use of tools such as his Grenadier Bracers, repeated ignition (especially with large explosions) will eventually result in the user's palms becoming worn down due to direct skin contact, causing pain to the user's arms and shoulders.[2][3][4]

As mentioned by Katsuki Bakugo, his bracers serve to reduce the risk of overusing his Quirk, as well as amplify the effects of explosions.[3] However, firing one of the bracers creates a strong recoil that hits the user's shoulder, though Katsuki seems to be completely unfazed by this due to his superior physical ability. Additionally, creating explosions with both arms at the same time causes their overall strength to be dispersed between both limbs, resulting in individually weaker explosions. Height: 1.72 m (5' 7")
Parents: Mitsuki Bakugo (mother); Masaru Bakugo (father)
Aliases: Kacchan; Dynamight​Kacchan

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 others' lead. However, thanks to Katsuki's own determination, perfectionism, and intelligence, he is a capable leader should others choose to follow his lead. During the fourth round of Joint Training, Setsuna Tokage admitted that even if her team attacked him at once, they had no chance of victory. In the end, despite Class 1-B's exceptional teamwork and Tokage's strategic planning, they failed to capture a single member of Class 1-A, mainly due to Katsuki's superior efforts, adaptability, and skills.
Musical Talent: Katsuki is very skilled at playing the drums, having attended drum lessons in the past. Explosion (爆破 Bakuha ?): Katsuki's Quirk allows him to secrete nitroglycerin through the sweat on his hands and detonate it at will to create explosions.[7] The more Bakugo sweats, the stronger his explosions become.[8] As stated by Best Jeanist, Katsuki has a strong grasp on the applications of his Quirk.[9] He often 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 explosions long enough to destroy a giant ice wall created by Shoto.

The blasts are powerful enough to send opponents flying without much time for them to react.[11] He can use them quickly enough to evade incoming attacks, even in mid-air.[10][12] 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.[13] 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. Additionally, because his Quirk relies on his sweaty hands, it is harder for his Quirk to work in colder climates. Without the sweat from his palms, he cannot utilize his Quirk to its fullest potential.

Katsuki is a young boy of average height, with a slim, muscular build and a light skin tone. He has short, spiky, ash-blond hair with choppy bangs that hang over his eyebrows. His eyes are sharp and bright scarlet.
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 his ankles, despite the fact he wears a belt.
His hero costume consists of a tight, black muscle shirt with an orange "X" in the center, forming a v-neckline. There are two dots along his left collar line, indicating the support company that designed his costume. His costume also has a metallic collarbone 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 holds grenades, holds up his baggy pants with knee pads, underneath which he sports knee-high black combat boots with orange soles and grommets. His mask is jagged and black, and as it goes around his eyes, a large, orange-rimmed flare shape protrudes from each side.
His winter hero outfit, he wears a large jacket with a high collar, instead of the usual sleeveless undershirt, though it has the same orange "X" design, so he can still sweat a sufficient amount, which is how his Quirk works.
During his internship with Best Jeanist, he wore a pair of skinny blue jeans with his hero outfit, instead of his usual baggy pants. His hair was also styled and parted to the side during this tenure.
