Overview: Katsuki Bakugo, also known as the Bombshell Hero: Great Explosion Murder God Dynamight, and called Kacchan by his close friends, is the deuteragonist of My Hero Academia. He was a student in Class 1-A at U.A. Hero Academy, training to become a Pro Hero. Appearance: Katsuki is a young man of above-average height with a slim, muscular build. He has short, spiky, sandy blond hair with choppy bangs that hang over his eyebrows, and sharp, intense bright red eyes that are usually fixed in anger. At U.A., he wears the standard U.A. uniform, although without the customary red tie. A few buttons are undone at the top of his white-collared shirt, and his pants are worn loosely, sagging at his ankles despite him wearing a belt with them. His Hero Costume consists of a tight, black, sleeveless tank top featuring an orange "X" across the middle, creating a V-neck design, with two black dots along the left side of the collar, which is the trademark of his costume's designer, Sasori Nimaru. The outfit includes a neck brace with rectangular ends, each having three holes on the side and front. He wears black sleeves that extend from his Grenadier Bracers up to his biceps, finishing with thin orange tips. He has dark green gloves with orange palms, and under his Grenadier Bracers are metal-plated forearm bracers. A dark green and orange belt, equipped with two grenades on each side, secures his baggy pants that have dark green drop‑leg holster pouches secured by thigh straps, and metallic knee guards with four orange bolts fastened into them and two on the side. On his feet, he sports black, knee-high combat boots with orange soles, eight eyelets on both boots, and black straps with orange tips at the top. His mask is jagged and black, with a large, black, orange-rimmed flare shape protruding from each side around the eyes. Personality: Katsuki is a crude, arrogant, short-tempered, self-centered, and aggressive person, especially during his early days. Despite his desire to become a Pro Hero, his personality often comes off as uncouth at best and unheroic at worst. This problematic behavior goes all the way back to his early days, where he gained an inflated ego as a result of being praised excessively for his powerful Explosion Quirk, leading him to bully a young, Quirkless, Izuku Midoriya. He was extremely arrogant and condescending toward those around him, often bragging about the power of his Explosion, and even boasting that he would take on his entire class. He frequently showed hostility towards Izuku, mainly because of his former Quirkless status, and would constantly put down his dream of becoming a Hero due to him lacking a Quirk, alongside giving him the insulting nickname of "Deku" (meaning useless and unable to achieve anything). He even threatened Izuku not to apply to U.A. High School and became angry when both of them passed the Entrance Exam, wanting to be the only person from his "garbage school" to make it there; showing that he has no qualms over hurting other people to get what he wants and is, by his own admission, a perfectionist. He further demonstrated himself to be cruel and merciless, obsessed with showing off his power by harming Villains even if they are immobilized. However, after being accepted into U.A. and experiencing several personal defeats, one of them even coming from Izuku, Katsuki has gradually changed into a less antagonistic person, albeit still retaining a lot of his unpleasant traits. Despite often being portrayed negatively, Katsuki's fierce character and competitive drive have granted him an important role among Class 1-A, as a sort of inspirational mood-maker. Quirk: Explosion: Katsuki's Quirk allows him to secrete nitroglycerin-like sweat from the palms of his hands and ignite it on command, allowing him to create strong explosions. The more Katsuki sweats, the stronger his explosions become. If Katsuki overuses this power, his forearms will start to ache. Katsuki has a strong grasp on the applications of his Quirk, something that was acknowledged by Best Jeanist, a top Pro Hero; not only can Katsuki use the explosions for attacking, he can also use them to propel himself and navigate through the air at high speeds, allowing him to fly at his opponents without giving them time to react, as well as evade incoming attacks, even while in the air. The shockwave from an explosion can even be used as a shield. Katsuki can keep up his explosions continuously, long enough to break through Eijiro's hardening Quirk and negate Shoto's "Heaven-Piercing Ice Wall" for a short while before being overwhelmed. As part of his training, Katsuki submerged his hands into boiling water to expand his sweat glands, then created chain explosions toward the sky to increase the scale of his attacks.
