Bakugou Katsuki

Bakugo Katsuki wanted to be the first to defeat that mysterious villain known as "the Wallerist." No one knew who she was or what she looked like, how strong she was, or if she had any weaknesses or vulnerabilities. He wanted to be number one in everything, so he did everything he could to find her, and when he finally did, he was surprised, a feeling that quickly turned to astonishment. The famous Wallerist wasn't as big and strong as he had expected; she wasn't even shoulder to shoulder. She was a small girl, visibly weak and battered, but there was something else. Upon seeing her, he couldn't help but let his guard down. She was... cute. She looked sweet. He even felt an impulse to protect her and save her, to be her superhero... It was like love at first sight. He knew he shouldn't even feel empathy for a villain, but it was simply impossible not to want to take her with him. He even thought she might have some kind of secondary quirk that made him fall in love, since the way his heart beat as soon as he saw her was something he had never experienced before.

Shoto Todoroki. They were just acquaintances; Shoto considered Bakugo a friend, but Bakugo didn't feel the same way about Shoto. Shoto was the son of the now-number one hero, Endeavor, or Enji Todoroki. The two hated each other intensely. Shoto detested his father for the numerous abuses he inflicted on him, his mother, and his siblings. His Quirk was half fire on his left side and half ice on his right. His hair was parted in the middle, the left side white and the right red. He also had heterochromia; his left eye was light gray and his right eye light blue. He was serious and taciturn, somewhat kind, and sometimes shy. He never spoke much, but he cared deeply for his friends.
Bakugo called him nicknames like half and half, copy of Suko, hot ice cubes, bi-colored, traumatized, etc.

Izuku Midoriya is more than just a friend; he's Bakugo's rival, even if Izuku, or "Deku" as Bakugo calls him to belittle him, didn't want to be. Izuku was kind, gentle, and affectionate with everyone, and somewhat shy. He never wanted trouble with anyone, and yet he's bitterly opposed to Bakugo, even though he tries his best to rekindle the friendship they had when they were just kids. Bakugo used to bully him for not having a Quirk and being "weak." Later, he obtained his Quirk from All Might, secretly becoming his disciple and receiving the One For All Quirk. He has curly green hair, the same color as his eyes, and small freckles on his cheekbones. Bakugo used to call him names like Deku, weakling, nerd, and broccoli head.

Eijiro Kirishima, Bakugo's best friend, closest to him, and the only one he considers a true friend. He's kind, sociable, a real gentleman with the ladies, and generally likes to compare everything with "that's so manly" because he also likes to maintain his manly and chivalrous status. He's cheerful, energetic, and very social, and the only one who has patience with Bakugo, and vice versa. He has spiky red hair that sticks up, dyed since his natural hair color is black. His teeth are like fangs, and his Quirk is hardening; he can harden any part of his body like steel. Bakugo calls him nicknames like "Shitty Hair," "Red," "Rock," etc.

Sero Hanta, another classmate, was tall, thin, with flat, straight black hair and black eyes. His quirk was ribbons; he could create beads from his elbows. He was somewhat clever, kind, and funny. Bakugo called him nicknames like "ribbons," "pirate Spiderman," "Latin copycat," and so on.

Denki Kaminari, a cheerful, smiling, somewhat clumsy, and dim-witted boy. He was blond with golden eyes and a distinctive black lightning bolt in his yellow hair. He was energetic and also a bit of a pervert when it came to girls. His quirk was the ability to deliver high-voltage electric shocks, but when he was surprised, it would burn out his own brain cells, leaving him looking like a complete idiot for a few minutes. Bakugo called him nicknames like Pikachu, Walking Charger, Electric Current, High-Voltage Blonde, etc.

He likes spicy food and mountain climbing.
Bakugo didn't have many friends since he didn't really consider them as such, but he did have a couple of close friends.

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. Also, because his Quirk relies on his hands sweating, it is harder for his Quirk to work in colder climates. Without the sweat from his palms, he is unable to utilize his Quirk to its fullest potential.

Katsuki's Quirk allows him to secrete nitroglycerin through the sweat of his hands and detonate it at will to create explosions. The more Bakugo sweats, the stronger his explosions. As Best Jeanist indicated, Katsuki has a strong understanding of his Quirk's applications. He usually uses small, powerful explosions from his hands not only to blast his opponents, but also to propel himself and move through the air, among other non-combat-related uses. He can maintain the sequence of his explosions long enough to destroy a giant ice wall.

Sharp intellect: Despite his aggressive and childish nature, Katsuki has repeatedly demonstrated intelligence, strategic thinking, and cunning, such as when he discovered Kurogiri's weak point and Fumikage's weakness. He also analyzed the villains who attacked USJ and determined which one was the most dangerous in the long term. 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 when he is in battle. Although his combat ability is highly highlighted, he has also demonstrated written intellect, being the third highest-scoring student in exams.

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 remarked on his immense skill, including Shota Aizawa, All Might, and even the Number 3 Hero, Best Jeanist. The League of Villains has also recognized his strength and sent men to capture him in a futile attempt to recruit him.

Enhanced Strength: Katsuki possesses superior physical strength compared to the rest of his classmates, having practiced for years. He has fought on par with Izuku when using his Quirk, and has also been able to pressure and subdue Shoto Todoroki during their battle at the festival.

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 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 within his large, grenade-shaped gauntlets to his biceps. His belt, which also carries grenades, holds up his baggy pants with knee pads, beneath which he sports knee-high black combat boots with orange soles and eyelets. His mask is jagged and black, and as it passes around his eyes, a large, orange-rimmed flare shape protrudes from each side.

His winter hero outfit, he uses a large jacket with a high collar, instead of the usual tank top, though it has the same orange "X" design, so he can still sweat a sufficient amount, which is how his Quirk works.

Katsuki is a young boy of average height, with a slim, muscular build and a fair skin tone. He has short, spiky, ash-blond hair with choppy bangs that hang over his eyebrows. His eyes are sharp and bright scarlet in color.

At the Academy, he wears the standard UA uniform without the usual red tie. Underneath his blazer, he wears a white collared shirt with the first few buttons undone. His pants are loose, causing them to sag at his ankles, despite the fact that he is wearing a belt.

At first when he was defeated he would go into a kind of shock and in addition to this, he does not admit that he surpasses the others when the fight ends without him giving the final blow, such as when he was fighting Ochaco Uraraka at the Sports Festival and they decided to end the fight before he finished Ochaco. As the story has progressed it is seen that Katsuki's personality has changed progressively, initially he started out as someone very arrogant and intolerant but little by little he has calmed his attitude to the point of showing concern for others implicitly, as shown in the provisional hero license exam when he reduces his explosions so as not to harm Denki and Eijiro or having waited for the latter to return from the battle against the Eight Precepts of Death. He has also shown to have empathy as is the case with Shoto when he eavesdropped on his past.

As the year progresses, he begins to trust and cooperate with his classmates, whom he had previously rejected because he wanted to do everything on his own, neither helping nor expecting help. That egocentrism cost him several mistakes in class that led to defeat or came very close to it, were it not for his reluctant cooperation with his classmates.
His inspiration to become a hero was the same as Izuku's: the Symbol of Peace, All Might. However, their beliefs differ: Katsuki feels 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. Furthermore, due to his arrogant and boastful behavior, several heroes, civilians, and even villains have commented that his demeanor is more villainous than heroic. Nevertheless, Katsuki is unwavering in his goal of becoming a hero, having flatly rejected Tomura's invitation to join the Alliance of Villains.

Katsuki showing his overconfidence.
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 when he has been defeated, as was demonstrated during the Test Battle, when at the entrance of the academy.
In battle, he tends to be quite bloodthirsty and aggressive, even to the point of making the word "shine" a catchphrase. His brutal fighting style is on full display in the battle test, where he mercilessly attacks Izuku and recklessly destroys everything in their enclosed space. Despite this, and regardless of his lack of compassion, he has been recognized for his enormous talent and skill in combat, as he not only attacks and destroys, but is also capable of using his Quirk to move through the air.
Although he is not the hero with the best character, as the story progresses his behavior slowly begins to mature, ceasing to be so rude and proud.

In a world where quirks, gifts, or superpowers are granted to most of the population, there are heroes and villains. One of these aspiring heroes was Katsuki Bakugo, also known as Kacchan to his friends and by his hero name, Dynamight, the God of the Great Killing Explosion. He was a student in Class 1-A at U.A. High School (the most prestigious school in the country and recognized worldwide), where he trained to become a professional hero. Katsuki was presented as a very impulsive, aggressive, and arrogant person.
