Katsuki Bakugo (known as Kacchan by his childhood friends,) is one of two main protagonists of My Hero Academia. He is a student in UA's hero department and a member of class 1A. He is currently training to become a pro hero.


Katsuki is a young man of average height, with a rather narrow but muscular build and lightly tanned skin. He has short ash blond hair which spikes upwards at all angles away from his head, but sits low over his forehead, coming down to his eyebrows, and his eyes are sharp and thin, bright red in color.

At school, he wears the standard U.A. uniform, save for the customary red tie, and underneath his blazer, he wears a white button-up shirt with the first couple of buttons casually undone. Despite wearing a belt along with the uniform's dark turquoise pants, they're not pulled up all the way, giving them a very baggy appearance, all typical of 'delinquent' style in Japan.

His hero costume is composed of a tight black sleeveless tank top, an orange “X” across the middle, the two upper prongs the v-neck collar of his shirt. There are two dots along the left line of his collar, indicating the support company that designed his costume.[2] His costume also has a metallic neck brace fashioned and used as a collar with rectangular ends, three holes in each of them. His sleeves reach from within his large grenade-like gauntlets to his biceps, and his belt, which also carries grenades, holds up his baggy pants with knee guards, below which he sports black, knee-high combat boots with orange soles and eyelets. His mask is jagged and black, and as it goes around his eyes, a large, orange-rimmed flare shape protrudes from each side.

In the winter months, he wears a large jacket with a high collar, rather than the usual tank top, although it does have the same orange “X” design, so he can still sweat a sufficient amount, which is how his Quirk works.

While interning under Best Jeanist, he wore a pair of blue jeans along with his hero costume rather than his usual baggy pants. His hair was also combed during this tenure, and parted to one side.


Katsuki is a crude, arrogant, and aggressive person, especially at the beginning of the series. Katsuki tends to come off as an anti-hero, if not downright villainous for those not familiar with him. This problematic behavior goes all the way back to his early childhood days when he was known to bully a young, Quirkless Izuku Midoriya. However, after being accepted into U.A. High School 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.

Determined and thirsty for victory, Katsuki smiles eerily when in the middle of a battle. He is incredibly focused on achieving his own authentic victories and has learned to never underestimate his opponents. Katsuki is not only very talented at fighting, but also very intelligent and extremely perceptive, capable of strategic planning and holding some of the highest grades in his class, to the point that some even consider him a natural genius.

While a rather volatile hero-in-training, which is seen as villainous by many outside of his class, Katsuki is smart enough to discern who his enemies and allies are. He is not known to be particularly warm and open with the people on his side, but will act less unfriendly and sometimes even kind to those that manage to earn his respect. Because of his attitude and vulgar language, Katsuki's U.A. classmates often react negatively to him, although they have come to appreciate his skills and warm up to his personality.[3] Katsuki matures slowly through his time at U.A., coming to befriend some of his classmates and willingly engaging in social interaction with his fellow classmates, though remaining aloof and solitary for the most part.

Katsuki tends to disregard the notion that Quirks shouldn't be used in public, and will activate his Quirk for a number of reasons, such as to intimidate someone, to punctuate a point, out of frustration, or even if he just feels like showing off. Katsuki values honesty highly and never lies, to the point his brash candor is seen by some as rude and unsympathetic. He is never afraid of speaking what's on his mind and will notice when people are not being truthful to him. This shows that, despite his anti-social habits, Katsuki actually has great judgement of character.

Due to the constant praise of his abilities and his powerful Quirk, Katsuki developed a superiority complex, and because of that, he desires to be the first and best at everything. As pointed out by many people, Katsuki loves to win above all else and cannot stand it when he doesn't, leading him to lose his already short temper or, less often, sulk. As such, he is fiercely competitive and will never settle for less than the number one spot. However, Katsuki also values hard work and fair play, and will refuse to acknowledge a winning result if he feels that his victory was not earned fairly. He detests being looked down by others, which normally angers him, and will hold contempt towards those that don't take him seriously, while recognizing the effort of those that manage to put up a challenge against him, like, for example, Ochako Uraraka, Eijiro Kirishima, and Denki Kaminari.

Katsuki is immensely prideful and prefers to act alone, as he hates the idea of having to rely on others to assist him unless he is recognized as the absolute leading figure within a team. At the beginning of the series, Katsuki's cooperativeness was nothing short of atrocious, often ignoring his partners' ideas and suggestions for his own very direct approaches. After a while, his team working skills gradually keep improve, but Katsuki still comes off as condescending to his teammates due to his usual tone, but he now acknowledges their importance, protecting them from harm while expecting them to do the same for him in return.

Katsuki's pride has cost him victories on numerous occasions, like the Battle Trial and the Provisional Hero License Exam. His pride is so intense that, when pitted together with Izuku against All Might, he outright refused his partner's help, even saying that he'd rather lose than ever work with Izuku to pass the exam by using Izuku's proposed plan. However, after realizing the true difficulty of the exam and being confronted by Izuku, Katsuki was able to put his pride aside temporarily in order to cooperate with Izuku effectively.

Katsuki has a more vulnerable side, having been led to tears due to damaged pride a few times. Katsuki has also shown moments of fear and guilt, the latter due to viewing himself and his own weakness as the cause of All Might losing his remaining power and retiring as a hero. Katsuki is capable of being grateful, and has gone out of his way to repay those who've helped him. Still, due to years of misunderstandings and tension, Katsuki has difficulty doing the same thing towards Izuku.

While his inspiration for becoming a hero was the same as Izuku's, the Symbol of Peace, All Might, their beliefs differ: Katsuki feels 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 conceited behavior, various heroes, civilians, and even villains have commented on it. However, Katsuki is unwavering in his aspirations of heroism, having outright refused Tomura Shigaraki's offer for him to join the League of Villains, even after being offered power and the ability to 'win'.


Overall Abilities: Katsuki has proven to be one of the strongest students in Class 1-A, earning 3rd place in the Quirk Apprehension Test, while placing first place in both the U.A. Entrance Exam, having the most villain points, and U.A. Sports Festival, although his last opponent, Shoto Todoroki, basically threw the match at the last moment. Katsuki's fighting style is all-out offense, using his Quirk's propulsive abilities to close the distance between him and his opponents, followed by a bombardment of close-range attacks that often start with a powerful right hook. Katsuki is able to use his Explosion to propel himself through mid-air, blind opponents, and release long-range blasts, among other applications. Explosion is a versatile Quirk, especially for battle situations, as the recoil caused by the blasts can be exploited by Katsuki for mobility purposes.

During the U.S.J. Incident, Katsuki was able to singlehandedly overpower and immobilize Kurogiri, a highly capable villain. At the Sports Festival, he was able to defeat Fumikage Tokoyami and Shoto Todoroki, who are also considered two of the strongest students in Class 1-A (although they had disadvantages respectively in their fights against Katsuki, despite these limitations, they still proved to be strong). Even though Shoto was defeated by Katsuki in the Sports Festival, Katsuki acknowledges that Shoto should have won their battle if had used his full power.[4] Many notable Pro Heroes such as Shota Aizawa and All Might have praised Katsuki's prowess; even the League of Villains have taken notice of Katsuki's strength and went as far as kidnapping him even if it meant losing members of the Vanguard Action Squad as his potential membership would have far exceeded the risk. Katsuki is recognized as one of the stronger students of Class 1-A, as noted by Pixie-Bob.[5] Izuku Midoriya Stated that the entire Bakugou Escort Squad (consisting of himself, Shoto Todoroki, Katsuki, Fumikage Tokoyami, and Mezo Shoji) working together, have the potential to take on someone of All Might's caliber.

He was able to defeat Izuku during their second fight when the latter was using 8% of One For All despite being fairly injured from the fight, and Izuku fighting on par with Katsuki for some time. During the Joint Training Arc, Katsuki claimed he has gotten stronger since his subsequent battle with Izuku. Katsuki, with the help of his teammates, was capable of defeating Setsuna Tokage, a recommended student who is not only the strongest student in Class 1-B, but was thought to have the potential of defeating Katsuki. It is unknown if him defeating her is proof of his claim of getting stronger.

  • Enhanced Strength: Katsuki possesses above average physical strength, as he was able to pressure and overpower Shoto Todoroki, a powerful combatant during their battle, although the latter was holding back. He was also capable of fighting on par with Izuku even when the latter is using his Quirk at 5-8%. Most notably, Katsuki is able to use his Grenade Bracers without any recoil due to his physical strength, whereas Izuku nearly dislocated his arm just from using one.

Keen Intellect: Despite looking like he'd just be a punk with no brains, Katsuki has proven to be extremely intelligent and strategic. While he occasionally doesn’t have preemptive strategies like most people, he does analyze his opponents weaknesses in the midst of battle. However, despite his analytical skills, Katsuki sometimes overlooks minor and crucial details. After he and Eijiro Kirishima intentionally lunged themselves at Kurogiri, Katsuki was able to figure out that part of Kurogiri's physical body has to be present when using his Warp Gate, so Katsuki targeted that said portion and successfully immobilized the villain. Even when fighting the weaker villains at the U.S.J., Katsuki quickly assessed which of the attacking villains were the most dangerous threat in the long term.

During the Cavalry Battle of the U.A. Sports Festival, he formed a strategy using the quirks of his teammates in order to get the headbands of Neito Monoma and was successful in doing so. In the climax of his battle with Ochako Uraraka, he surmised that she had a plan prepared to use against him, but he incorrectly assumed that Izuku was the one that gave her the strategy to begin with; this assumption was corrected when Izuku clarified he wasn't involved with Ocacho's strategy. In the battles against Eijiro and Fumikage, Katsuki barraged them both with explosions in order to discern their respective Quirk weakness: Eijiro's Hardening weakens in drawn out battles, and Fumikage's Dark Shadow is susceptible to light. At the beginning of his battle with Shoto, Katsuki effortlessly used his explosions to tunnel through the former’s "Giant Ice Wall", and noted that Shoto's aim was off, realizing the wall of ice wasn’t as potent as it was when Shoto battled against Hanta Sero. When paired with Izuku in the final exams, Katsuki begrudgingly put his insubordination aside and came up with a compromise that involved him and Izuku using his Grenade Bracers to unleash maximum firepower at point-blank range to briefly stun All Might, and afterwards, the pair rushes to the escape gate. Katsuki's plan worked for a while, but he oversaw All Might's incredible speed, resulting in the Symbol of Peace destroying his gauntlets, making the duo lose their maximum firepower.

Pro Heroes (such as All Might) have mentioned several times his great potential and battle-sense. Shota Aizawa stated that in battle Katsuki shines his brightest. Another testament of intellectual prowess, is that Katsuki scored 3rd place in the midterms, proving how academically efficient he is. Since the League of Villains took Katsuki to their hideout and took time to explain their plan in order to recruit him, Katsuki correctly deduced that the villains needed him alive, so they weren't going to risk killing him. Katsuki was also able to piece together the truth of Izuku's Quirk after being kidnapped by the League of Villains, and seeing All For One steal Quirks which coincided with Izuku's words of getting a Quirk which he correctly deduced came from All Might, with whom he noticed Izuku had a connection to. This is another facet of Katsuki being considered a natural born genius.

  • Leadership Skills: During round four of the Joint Training, Setsuna Tokage admitted that even if her team had attacked him all at once, they stood 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 Katsuki's team, mostly thanks to Katsuki's efforts, adaptability, and skills.

Musical Talent: As shown during the U.A. School Festival Arc, Katsuki is highly skilled at playing a drum kit, having gone through classes in the past.


Explosion: Katsuki's Quirk allows him to secrete nitroglycerin-like sweat from his palms and detonate it at will to create explosions. The more Katsuki sweats, the stronger his explosions become. As stated by Best Jeanist, Katsuki has a strong grasp on the applications of his Quirk.

Katsuki usually uses small, powerful explosions from his hands to not only blast his opponents but to propel himself and navigate through the air as well. He can keep up his explosions long enough to break through Eijiro's hardening Quirk,[11] and negate Shoto's Giant Ice Wall for short while before being overwhelmed. The blasts are powerful enough to send Katsuki flying at his opponents without much time for them to react, and he can use them swiftly enough to evade incoming attacks, even in the air.

As part of his training, Katsuki submerged his hands into boiling water to expand his sweat glands, then create chain explosions to increase the scale of his attacks.

  • Blast Rush Turbo ( Bakusoku Tābo?): Katsuki throws his hands back and uses explosions to propel himself. He uses this both on the ground to increase his speed and through the air to achieve a pseudo form of flight. He first used this technique on the ground during the Quirk Apprehension Test.The first time he used it to fly was during the Obstacle Race.
  • Stun Grenade (: Katsuki starts by creating a sphere of light between his hands that explodes into a large scale flash. Similar to the effect of an actual stun grenade, the flash of light blinds anyone close by. He first used this technique to defeat Fumikage Tokoyami.
    • Zero Distance Stun Grenade (ゼロ: A variation where Katsuki fires off his Stun Grenade at point blank range of the opponent to immediately stun and immobilize them with little lasting damage. [16] This variation was first used against Setsuna in the fourth round of the Joint Training Battle.

Howitzer Impact (: Katsuki takes to the air and uses explosions to propel himself in a circular motion to create a tornado. This tornado builds up oxygen to fuel the incoming explosion. After colliding with the ground, Katsuki releases the powerful aforementioned explosion. Present Mic compared the effectiveness of the technique to that of an actual missile. Katsuki first used Howitzer Impact in the final match of the U.A. Sports Festival Finals.

  • AP Shot (: Katsuki stretches out one of his hands and uses his other hand to form a circle on the palm of his outstretched hand. Katsuki then fires an explosion through the circle, which creates a concentrated blast beam. By focusing the path of his explosions into a single point instead of around 2 his whole palm, Katsuki creates a concentrated blast with reduced area of impact, but with enough power to successfully pierce solid concrete.
        • AP Shot: Auto-Cannon (: A rapid-fire version of his AP Shot Technique. The explosion power is reduced in order to avoid dealing severe damage to human targets.This variation was first used against Seiji Shishikura in the first stage of the Provisional Hero License Exam.
      • Explode-A-Pult ( Ekusu Kataparuto?): While in mid-air, Katsuki grabs an opponent with one of his arms, then propels himself in a spinning motion by firing explosions with his free arm. Once he gains enough momentum, Katsuki forcefully throws his opponent with the aid of another explosion. He first used this technique against Togaru Kamakiri in the fourth round of the Joint Training Battle.
