Quirk: Half-Cold Half-Hot
Shoto’s Quirk splits his body vertically. His right side generates ice, and his left side generates fire. This dual nature makes him one of the most versatile and powerful heroes of his generation.
Ice Abilities (Right Side)
Heaven-Piercing Ice Wall: Shoto creates a massive glacier instantly. It can trap enemies, block attacks, or alter the battlefield landscape.
Mobility & Trapping: He freezes the ground to slide at high speeds or instantly freeze opponents' feet to immobilize them without permanent harm.
Fire Abilities (Left Side)Intense Pyrokinetics: Shoto shoots powerful streams of fire for long-range attacks.
Flashfire Fist: A technique learned from Endeavor. Shoto raises his internal temperature to maximize his speed and heat, unleashing explosive, concentrated fire strikes.
Ultimate & Combined Techniques
Flashfreeze Heatwave: Shoto cools the air around him with ice, then rapidly heats it with fire. This sudden temperature shift causes the air to expand violently, creating a massive, devastating explosion.
Coldflame Pale Blade: A refined technique where he shapes his fire into a localized, sword-like burst of energy for precise offensive strikes.
Phosphor: Shoto’s peak technique. By circulating his blood to mix fire and ice energies together, he achieves a state of balance. Instead of just using fire or ice separately, he generates a unique "cold fire." This allows him to unleash massive attacks without overheating or freezing his own body, and it can even neutralize external fires.
Tactical Traits
Temperature Regulation: Shoto must balance both elements. Relying only on ice causes frostbite and slows his movements, while overusing fire causes heatstroke. Using the opposite element regulates his core temperature.

After discussing the matter with his mother and siblings however, Shoto offers his hand to a grieving Endeavor, realizing that it's not his fight alone and that their family must unite together in order to stop Dabi. Shoto also joins Class 1-A in tracking down a rogue Izuku, convincing him to return to U.A. and not to shoulder everyone's burdens by himself. Like Izuku, Shoto is faced with scrutiny by the public for being Dabi's brother and Endeavor's son, but resolves to help fix things along with the rest of his friends.

Shoto remains relatively cold towards Endeavor and has made it clear that forgiveness for his past treatment of him and his mother is difficult, but has also demonstrated worry about his father's safety. Ever since Endeavor tried to repair his relationship with his family, Shoto has taken a cautious, yet hopeful approach to this development. Notably, he is shown to still care for his father despite their poor relationship, being shocked when he was horribly injured during his battle against Hood, shouting at his father that he was watching him, and later collapsing from relief in front of his classmates and teacher after seeing that Endeavor had survived. He also got permission to visit his home so he could see him, but once again gave Endeavor the cold shoulder while making a dry comment about his new scar. Unlike his brother Natsuo, Shoto does not seem against the possibility of forgiving his father; however, he has made it clear to Endeavor that he must earn it. While ruminating over the matter, Izuku believes that Shoto is preparing to forgive his father and is waiting for the right time to do so. During the Paranormal Liberation War, Shoto was deeply shocked and devastated to learn that Dabi from the League of Villains was his seemingly deceased eldest brother, Toya, and was driven to a tearful rage upon learning that Dabi was responsible for their encounters with Starservant and Ending, especially when the latter villain had nearly killed Natsuo. Following the war while recovering in Central Hospital, Shoto sees his old self reflected in Dabi, realizing that his brother's hatred for their father led to Toya becoming a villain, and resolving that he must be the one to stop him.

Despite his difficult past, Shoto doesn't allow his hatred of Endeavor to completely cloud his judgement and still acknowledges him for his skills and capabilities as one of Japan's top Heroes. He chose to intern at his father's agency during the Hero Agency Internships and later the Hero Work-Studies program, although he made it clear that this was purely for his own benefit and learning experience rather than any desire to spend time with him. Shoto is quite reflective of his own growth, realizing how much Izuku's words had changed his perspective and how better he became. Due to this, Shoto was not against his father deciding that he would try and make amends with his family and become a better person, knowing from experience that a single thing can change a person if they allow it to. However, Shoto's grudge towards Endeavor has not yet disappeared, even if he respects his father's ability as a Hero, self-admitting that such resentment can't vanish so easily and that he was wrong in trying to bury it. Having been denied a normal childhood so that his father could train him to realize his own selfish ambitions, Shoto still holds various psychological scars, which tend to reemerge when others compare him to Endeavor. Because of this and Izuku's influence, Shoto now strives to become a Hero, but without walking the same path his father did. Shoto even tells Endeavor straight to his face that he only intends to use him to improve himself and to cut all the "caring father" nonsense out in front of his friends, words that visibly affected Endeavor, who thought that his son was finally opening up to him.

Ironically though, Shoto's animosity towards his father made him more like how Endeavor was, being apathetic and indifferent towards others while obsessively focusing on his own goal of rejecting his father. Shoto takes his rejection of his father to a new level during the U.A. Sports Festival, in which he was forced to use his flames during the cavalry battle against Izuku Midoriya. Upon noticing Izuku's closeness to All Might, seeing that the two were somehow connected and even believing at first that Izuku was All Might's illegitimate child, he sought to take Izuku down and win the festival using only his ice, believing that doing so would be the perfect way to reject and spite his father. Upon first meeting him, Inasa noticed that Shoto had the same hate-filled glare that Endeavor had due to his hatred driving him, and Izuku realized that Shoto was unable to look past his grudge, with his pain and anger holding him back from his full potential. During his match with Izuku in the U.A. Sports Festival, Izuku's speech made the memory of his mother's supportive words resurface, and for the first time since his childhood, Shoto used his firepower in combat. After the battle, Shoto had mixed feelings about using his left side, but after reconciling with his mother, Shoto eventually came to terms with the half he once hated and became willing to train it further, now realizing that it is his Quirk and not his father's. Despite being scarred by her as a young child, Shoto shows no hate or disliking towards his mother, visiting her often ever since the end of the Sports Festival. Shoto draws his heroic values from All Might, a trait he shares with Izuku and Katsuki Bakugo, having fond memories of watching the Symbol of Peace on television with Rei.

While usually quiet and reserved, Shoto initially possessed a moderate level of arrogance, which, combined with his solitary tendencies, sometimes made him take the initiative without considering the opinions of others, displaying confidence that he could take on any obstacles with his own strength. He used to be much more unfriendly as well, to the point where his cold attitude caused Inasa Yoarashi to resent him while he was none the wiser. Even in the present, Shoto seems to prefer acting alone, although he only does this for practical purposes since doing so allows him to unleash his full power without worrying about friendly fire. Calm and composed yet brutal in combat, Shoto is well-grounded on the ethics of heroism, only wishing to subdue his frozen opponents instead of killing them by prolonging the freezing. Shoto once had a deep loathing for his fire abilities, which he inherited from Endeavor, as it symbolized his father's wickedness towards him and his mother as well as what he was born to be: a tool to surpass All Might, a fate that he detested. As such, Shoto decided to rely solely on his freezing power and never use the other half of his Quirk in battles (save only for melting his ice), going so far as to cover his left torso and arm with ice in his first Hero Costume to symbolize his rebellion against his father. Shoto often felt bothered by Endeavor's mere presence, and could barely contain his anger while talking to him, especially whenever the Pro Hero brought up the purpose he had intended for his son since before birth.

Shoto originally had a cold, aloof personality, which stemmed from his abusive upbringing and complicated family life. Focused and unemotional, Shoto preferred to keep things to himself instead of hanging out with others. After the events of the U.A. Sports Festival, however, Shoto notably became more sociable and kinder than ever before, even gaining a sense of humor and occasionally smiling, although still retaining some fragments of his previous distant attitude and nonchalant demeanor. After the Provisional Hero License Course, he began opening up more to his classmates and has lightened up from his usually serious demeanor. Nonetheless, Shoto is not quite used to socializing yet, coming off as a bit dense when understanding certain phrases and figures of speech (such as when Camie Utsushimi asked him for his phone number or when Mt. Lady tried flirting with him) or when trying to read between the lines (such as when he inquired about Izuku Midoriya possibly also having two Quirks after he first used Blackwhip).

His updated costume consists of a dark blue heat-resistant jacket with elbow-length sleeves, its collar high, with a cooling/heating device within it and joined in the center by a gray clamp strap. His baggy pants of the same color as his jacket, a metal-plated tactical vest with red accents, which now functions as both a heater and radiator and white boots similar to his initial costume, with the soles equipped with spikes and a thin zipper running down the center of each of them a darker pale gray. He also sports a beige utility belt with red accents around his waist, which can hold four little metal capsules containing medical supplies, with two hanging off the front and two on the back. In preparation for the Provisional Hero License Exam, he adds two red wrist guards with metal plating, which help regulate his body temperature after his attacks, and his boots now have a set of straps on the top of the foot.

Shoto is a moderately tall and rather muscular young man who is well-built for his age, stemming from his intense training as a child. He has short hair that doesn't pass his neck, with bangs that fall to his nose bridge, parted twice to avoid obscuring his vision. His hair is evenly split between white on his right side and crimson on his left, this unusual coloring being due to his Quirk. As another result, he also possesses heterochromia iridum, causing his quite thin and reserved eyes to have two differently colored irises; his left being turquoise, while his right is a dark gray. Additionally, he has a large burn scar on the left side of his face, which reaches from his hairline to halfway down his cheek. He usually has a serious expression, but despite this, several of the girls in his class have claimed that he is quite handsome, as Mina Ashido even goes as far as to say that he's the best-looking guy in Class 1-A. At U.A., he wears the standard male uniform: a light gray blazer with dark turquoise trimmings over a white dress shirt, dark blue-green dress pants, a red tie. He replaces the standard brown dress shoes with casual pale cyan and gray lace-up sneakers.

Shoto Todoroki (轟とどろき焦しょう凍と, Todoroki Shōto?), also known as the A.C. Hero: Shoto (エアコンヒーロー ショート, Eakon Hīrō Shōto?), is the tritagonist of My Hero Academia. He was a student in Class 1-A at U.A. High School, and one of two to get in through official recommendations. He is also the youngest son of Endeavor, the former No. 2 and later No. 1 Pro Hero, and Rei Todoroki. Shoto's elder siblings are Toya, Fuyumi, and Natsuo.

Izuku Midoriya, the protagonist of My Hero Academia, starts as a quirkless boy but becomes the ultimate hero by inheriting One For All (OFA) from All Might. This legendary quirk stockpiles raw power and allows him to access the unique abilities of its previous users.
Here is a summary of Izuku's complete skill set:
Core Power & Applications
Stockpile Power: Grants superhuman strength, speed, durability, and agility. Initially, his body breaks under the pressure, forcing him to adapt.
Full Cowling: A technique where Izuku channels a manageable percentage of OFA (e.g., 5%, 20%, 45%) throughout his entire body simultaneously, increasing his overall mobility and defense.
Shoot Style: A combat style focusing on powerful kicks rather than punches, protecting his heavily injured arms and maximizing his agility. Quirks of the Previous Vestiges
As OFA matures, Izuku unlocks six additional quirks embedded within the core power:

Gearshift (2nd User): Allows him to change the speed of any object or person he touches, bypassing the laws of inertia to accelerate attacks instantly.
Fa Jin (3rd User): Stores kinetic energy through repetitive movements and releases it in explosive bursts, mimicking 100% of All Might's power without the physical recoil.
Danger Sense (4th User): Acts like a sixth sense, alerting Izuku to nearby threats, negative emotions, and incoming attacks.
Lariat / Blackwhip (5th User): Generates tendrils of black energy from his body, used for capturing enemies, swinging across environments, and enhancing mobility.
Smokescreen (6th User): Emits thick clouds of purple smoke from his body to obscure the enemy's vision, create distractions, or setup stealth attacks.
Float (7th User): Grants the ability to levitate and fly through the air, giving him supreme aerial combat advantages.
By combining Fa Jin, Gearshift, and Full Cowling, Izuku can achieve an artificial "120% Output," making him fast and strong enough to overpower the world's greatest threats.

Following the conclusion of the Paranormal Liberation War, Izuku's behavior suffered a drastic change from the trauma brought on by the war, seeing countless people having their lives ruined from Japan being thrown into chaos, along with All For One relentlessly targeting him for his Quirk. While his desire to save everyone remained, Izuku became much more cold, distant, and focused, leaving U.A. in order to protect all his classmates while leaving them letters explaining the truth about One For All and him being the Villains' main target. He was also traumatized and deeply enraged at witnessing the near death of Lady Nagant, seeing how All For One coerced and nearly killed her all as a means to provoke him. When All For One vowed to break Izuku both physically and mentally, he became increasingly paranoid about how much harm he would bring to those around him. The overwhelming stress and burden resulted in him rushing into fights and leaving behind All Might and the other Heroes looking after him so that no one else will get hurt. His disregard for his own well-being becomes the worst it ever has been as well, neglecting to look after his basic needs like sleeping and eating. Katsuki has noted this behavior to be very similar to how All Might was when he was the Symbol of Peace. This increasingly driven, serious side of him has even caused civilians to note that he doesn't look like a hero. After his friends from U.A. get through to him and take him back in, these traits seem to have diminished, with him now being determined in stopping All For One alongside his friends, teachers, and allies.

Izuku also possesses an empathetic side and has developed a desire to want to understand the Villains he has faced, and potentially save them from themselves. While initially believing Tomura to be a madman who just wants to meaninglessly hurt others, after learning about his tragic history and sensing the pain in his heart through their connection between One For All and All For One, this re-invigorates his belief that a great Hero is someone who saves others, not kills, and because of this, desires to learn how they became Villains and see if there is any way to prevent a fight, though he does concede he very well may have to kill Tomura. Despite this desire, Izuku will still give his all in a violent fight (recognizing that Villains must be stopped no matter what in order to save innocent lives), especially if a Villain cannot be reasoned with and no other options are available. When facing Overhaul, Nine, and Dark Might, Villains too powerful to ordinarily subdue, he unleashed the full power of One For All and dealt them potentially lethal wounds, and showed no hesitation in finishing off "All For One" once saving Tomura was rendered impossible. However, when possible Izuku will hold back and attempt to save his foes, even when such a notion seems unlikely and is deemed pretentious by others. Izuku puts aside his personal feelings even for Villains he personally despises, such as Overhaul, and still offers them a chance.

Izuku is an avid collector of All Might merchandise, has knowledge of his numerous feats of heroism (no matter how minor), and emulates many of his traits. Having inherited his Quirk, one of Izuku's current priorities is to be able to live up to his idol's legacy, as he is always looking for ways to improve his usage of One For All, being aware of the immense pressure that comes with succeeding the Symbol Of Peace. The unwavering trust and approval Izuku receives from All Might has been vital to his development as a hero, especially when the aforementioned feelings of self-doubt and unworthiness plague his mind. Izuku appears to have a more brash and abrasive side to him, which typically shows up when he finds himself in combat. This side of him makes him act more like Katsuki, being rather loud and unwavering, and also with a strong drive towards victory. He claims that this is because he sees Katsuki as the embodiment of what someone who strives for victory should be. He has also admitted that he doesn't like this side of him very much and tends to keep it in check. He does, however, find himself giving in to this almost feral rage when in dire situations and faced against opponents who had brutally hurt people he cares for, like in his battles against Overhaul and Tomura.

Izuku will routinely break himself for the sake of others, even if it's not completely necessary, such as demanding Shoto to unlock his full potential by using his fire side. This can make Izuku somewhat short-sighted, as he continued to break his arms, despite warnings he could permanently paralyze them and cut his hero career short. Eventually, Izuku relented, adapting his battle style to put less strain on his body. Though when he's in a particularly tight situation, he'll pull back on old habits. Izuku is known to help or lecture people with personal and emotional problems, regardless of if it's his business or not, claiming that a hero should meddle in other people's lives. This audacious spirit, while initially viewed as perplexing or even insane by others, is also recognized by many, and has earned him the loyalty, gratitude and respect of characters that were previously antagonistic towards him such as Tenya Ida, Shoto, Hitoshi Shinso, Kota Izumi, Sir Nighteye and even the likes of the Hero Killer: Stain and Lady Nagant. He has a strong fascination with heroes and is shown well-versed in their history, sometimes even surprising the heroes themselves with his vast knowledge of their abilities and past exploits. He is prone to geeking out and rambling on about the heroes he meets, often bringing up their history and accomplishments, while also being eager to share this knowledge with others. Of all heroes, the Symbol of Peace, All Might, has impacted and modeled Izuku's life the most. Many of Izuku's decisions and actions result from his desire to become a Pro Hero similar to All Might, and thus he has a great devotion to him.

Izuku is a quite diligent and strong-willed student, being extremely (and sometimes scarily) enthusiastic about topics related to heroes. His dream drives him to write down notes about everything he learns about heroes' Quirks and fighting capabilities. Thanks to this practice, Izuku has developed a great analytical mind and can form complex battle plans in a few seconds, factoring in the best ways he can utilize the Quirks of allies and enemies alike for his own advantage. Izuku externalizes his observations through endless mumbling, a habit that annoys or creeps out his peers. Izuku often writes down his observations in a variety of notebooks he titles as Hero Analysis for the Future; he checks on them regularly during school activities, during his free time, or at night. Izuku is caring and emotional, never hesitating to help or rescue someone in danger, even if he knows that he might not be strong or otherwise qualified enough to do it. Often, he does this on instinct, taking a more careless approach than the usual overthinking he goes through and putting himself in peril in order to protect someone. All Might claims that this trait gives Izuku the most important natural and innate instinct to be a hero; the pure and genuine desire to help people. However, Izuku putting others' lives above his own can go to the extreme, to the point where he has little to no sense of self-preservation. Katsuki speculates that the bullying Izuku received for being Quirkless made him internalize that his life has less worth.

Izuku is a very timid, reserved, and polite boy, frequently overreacting to abnormal situations with exaggerated expressions. Due to yeаrs of being looked down on by Katsuki for lacking a Quirk, he is initially portrayed as insecure, tearful, vulnerable, and non-expressive. These traits are especially present around Katsuki, who also constantly harangued him for his aspirations to become a hero. However, after being accepted into U.A., making new friends, and facing Katsuki during the Battle Trial Arc, Izuku gradually matures into a more confident and braver person who's always eager to prove his worth as a hero, eventually developing strong leadership skills, which combined with his passion and strategic abilities, have turned him into a central figure within Class 1-A alongside Katsuki.

His second costume, known as "Costume Beta", was upgraded by the costume designers, as a few changes were made. As such, it now looks sturdier and more combat-ready in appearance, with the color now a darker teal with black outlines instead of white. It includes light beige shoulder pads, black knee pads that have been extended, now reaching up to his thighs and lower into his shoes, and the back pouch on his belt is removed. His new gloves are also tinted light beige and are decorated with two blue stripes, and his respirator is now metal, with a more diamond-shaped design in the center, and has eight holes in the front, looking much less like a smile. Izuku's mask is still present, with the long ear-like protrusions being shorter, although he doesn't wear it much. During Class 1-A's week of Ultimate Move Training, Izuku had his costume upgraded again to suit his new fighting style, Shoot Style, by adding black iron soles to his red boots to increase the power of his kicks. He also had arm braces were, along with wrist straps and extending the blue stripes around his biceps, and both his iron soles and knee pads have yellow bolts fastened into them (originally added before the upgrade in the manga). He called upgraded costume "Costume Gamma".

Izuku is a somewhat short young man, with his round face being framed by a short mop of fluffy dark-green hair with bangs that fall just over his eyes. His hair curls up at odd angles around his head, casting noticeably dark shadows onto itself. His eyes are large and somewhat circular, with his irises being the same shade of green as his hair, which at times are very watery, and are usually stretched quite wide, giving him an innocent, energized appearance. He has a set of four symmetrical freckles in diamond formations, one on each cheek. He has often been described as "plain-looking" or "not standing out" by others. Though he was initially very skinny, Izuku has gained toned muscles after his ten months of extensive training with All Might, and as the series progresses, these are shown to become more developed and defined as he gradually grows stronger. At U.A., he wears the standard male uniform: a light gray blazer with dark turquoise trimmings over a white dress shirt and dark blue-green dress pants, along with a red tie which he doesn't do up properly, leaving it much shorter than how it should be. Instead of the plain brown shoes worn by the majority of the student body, he still sports his signature red shoes.

Izuku Midoriya (緑みどり谷や出いず久く, Midoriya Izuku?), also known as the One For All Hero: Deku (ワン・フォー・オール ヒーロー デク, Wan Fō Ōru Hīrō: Deku?), is the main protagonist of My Hero Academia. Born Quirkless, Izuku manages to catch the attention of the legendary Hero All Might, becoming his close pupil, as well as a student in Class 1-A at U.A. High School. All Might passed on his transferable Quirk to Izuku, making him the ninth and final wielder of One For All.

Explosion (爆ばく破は, Bakuha?): 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 also has an honorable side to him. Though he insisted that Izuku was unhelpful in trying to save him from the Sludge Villain, he did stop bullying the boy for ten months afterward, only resuming after they both got into U.A. out of anger for "ruining (his) perfect backstory". While he didn't believe the story about Izuku's Quirk belonging to someone else at first, as well as falsely assuming that Izuku had been hiding it from him the entire time, when he learned of All For One and his Quirk, he started to believe Izuku's words and pieced it together after seeing All Might's true form, confronting the former about his assumption. After All Might confirmed his deduction, Katsuki vowed to keep One For All a secret, being one of the initial few people to know about the true power of the Quirk. It is later revealed that Katsuki decided to help Izuku train One For All to atone for his past bullying, realizing what drove him to constantly torment Izuku was his own insecurities. During Katsuki's discussion with All Might about his connections to Izuku, Katsuki admitted that he bullied Izuku as an outlet as how he couldn't understand why Izuku always puts others before himself. In truth, Katsuki really cares for Izuku despite how he acts, and wishes for him to continue improving his strength and Quirks, unlike before where he ridiculed Izuku's efforts and told him how he wouldn't amount to anything. His caring and protective side is further proven when he heard that Tomura was targeting One For All, immediately realizing that the Villain leader would be going after Izuku and made attempts to keep Tomura away from him.

Katsuki is immensely prideful and prefers to act alone, as he hates the idea of being protected or having to rely on other people to assist him (which he takes as him being weak, causing him in turn to lash out) unless, in the latter's case, he is recognized as the unquestionable leading figure within a team. At the start of his time at U.A., Katsuki's cooperativeness was nothing short of atrocious, often ignoring his partners' ideas and suggestions for his own very direct approaches. His teamwork skills gradually improve, even if Katsuki keeps coming off as condescending through his usual tone. However, it's clear he now acknowledges their importance, protecting them from harm while expecting them to do the same for him in return. As a leader, Katsuki is mercilessly perfectionistic and will only be satisfied with complete, indisputable victories. By the time of the Remedial Course, Katsuki had started to mature a little to the point that he was able to advise a kid who acted similarly to him, stating that if the child continued to look down on others, he would not realize his own mistakes. Despite this growth, Katsuki has certain personality traits that he doesn't immediately get over, like joining the Class 1-A band during the U.A. School Festival under the pretense of "beating the other classes through music", or calling his classmates in the Joint Training Battle "Underlings". While far less smug than he used to be, his high opinion of himself has remained intact and he can still be partial to boasting whenever he does well or exceeds someone, especially 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, various Heroes, civilians, and even Villains have commented on his arrogance and conceit. However, Katsuki is unwavering in his aspirations of heroism, having outright refused Tomura Shigaraki's proposal for him to join the League of Villains because he views the villains as people who lose, rather than those who win like Heroes. Katsuki often has difficulty accepting his mistakes and learning from his shortcomings, fiercely denying them whenever they are pointed out by others, regardless of who does it. However, this doesn't mean Katsuki doesn't listen to advice, having come to realize his faults and how to somewhat improve on them thanks to the words and actions of other people like All Might and Best Jeanist, though he will never outright admit this due to his pride. He prefers to self-reflect in silence and solitude, becoming a bit more brooding during those periods. Katsuki's unchecked pride and aggression have cost him victories on numerous occasions, like the Battle Trial or the Provisional Hero License Exam, and it tends to worsen whenever Izuku is involved. Both boys share a sensitive history with each other, with Katsuki, in particular, being unable to completely overcome his issues with Izuku, although this has not stopped them from working together many times when the situation demands it.

Along with that, he detests being pitied or looked down on by others, 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, Ochaco Uraraka and Eijiro Kirishima. However, this does not apply to Izuku due to his long-held belief that he should be inferior to him, with the other boy's success, which he perceived as Izuku mocking him, instead making him angry and feel inferior. His ultimate goal is to be the Number One Hero and hates any indication that he isn't strong enough, or anyone that can rival him, such as Shoto. Because of his Quirk and talents, Katsuki is very confident and brave to the point where he is willing to go against anyone who challenges him. He never backs down from a fight and will go all out when facing such a powerful opponent. During the First Term Final Exam, Katsuki wasn't afraid to go up against All Might, even though he knew he had little to no chance of taking the Symbol of Peace down head-on. From taking on several villains at the Unforeseen Simulation Joint, Katsuki is shown to know when he is dealing with someone that is out of his league, as he let All Might face off against Nomu.

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, punctuate a point, out of frustration, or if he merely feels like showing off. Namely, he repeatedly used it to bully and intimidate Izuku growing up, and revelled in the fear the Quirkless boy showed him. Overall, Katsuki doesn't seem to care very much about what others think of him, barely containing himself from violent behavior (although he avoids other typical delinquent practices like underage smoking). Katsuki values honesty highly and never lies, to the point his brash candor is seen by some as rude and insensitive. He is never afraid of speaking his mind and will notice when people are not being truthful to him. This shows that, despite his anti-social habits, Katsuki is an excellent judge of character, making it hard to deceive him. Due to the constant praise of his abilities and powerful Quirk, Katsuki has 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. He is fiercely competitive and will never settle for less than the number one spot, having a compulsive need to always strive for victory and also prove people who doubt him wrong. However, Katsuki also values hard work and fair play, to the point of refusing to acknowledge a winning result if he feels that his victory was not earned by actual merit, as seen during the U.A. Sports Festival.

While a rather volatile Hero-in-Training who is prone to snap more than think, Katsuki is smart enough to discern his allies from his enemies. While not particularly nice or open with people who are on his side, or anyone else for that matter, he 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. Katsuki matures slowly through his time at U.A., coming to befriend some of his classmates and willingly engaging in social interaction with them, though remaining solitary for the most part. As he does with Izuku, Katsuki has a habit of bestowing insulting nicknames upon others, such as calling Tenya Ida "Four Eyes" because of his glasses, Denki Kaminari "Dunce-Face" because of how his Electrification Quirk dulls his thinking, Shoto Todoroki "Half and Half" or "Icy-Hot" because of his dual Quirk and appearance, and so on. He also refers to people he doesn't know as "Extras", treating them as little more than fodder or stepping stones to his victory until he faces them head-on. Despite this, he can address others properly when it matters, such as when he's serious or in the heat of battle.

Katsuki has a more vulnerable side, having been led to tears due to damaged pride a few times. After the Battle Trial, Katsuki, when he saw Izuku's ability to outsmart him during their match and the fact that he couldn't beat him head-on, alongside later witnessing Shoto's power, admitted that Momo Yaoyorozu was right about how reckless he was during his fight with Izuku. 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. Still, due to years of misunderstandings, tension, and pride, Katsuki has difficulty doing the same thing towards Izuku. 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 highly athletic and talented at fighting, but also very intelligent and extremely perceptive, capable of strategic planning and improvisation. Moreover, Katsuki's grades are among the highest of his class, and he already knew how to read perfectly by the age of four, evidence that he treats studying seriously. Katsuki also possesses surprising talent in other areas, such as cooking and music, though he doesn't show a particular interest in them. Overall, he is considered a natural-born genius with the potential to be one of the best Pro Heroes around.

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 middle 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.

Katsuki is a crude, arrogant, short-tempered, self-centered, and aggressive person, especially during his middle school 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 childhood 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).

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.

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. After the Paranormal Liberation War, Katsuki's school uniform is worn in a much neater fashion, which includes the red tie he previously forwent.
