Half Cold Half Hot(,Hanrei Han'nen?)半はん冷れい半はん燃ねん: Shoto's Quirk grants him the ability to generate ice from the right side of his body and flames from the left side.
After years of rejecting his father, Shoto has developed a preference for ice, even when fire would be a better option. This resentment also made it difficult for him to control flames. While he is capable of using both elements simultaneously, he is not used to it and still needs to practice dual-wielding. While training for his ultimate move, he stated that using both abilities at once slowed him down.
If he overuses one element without using the other, his body temperature will be affected; half ice will cause frostbite, and half fire, heatstroke. However, until he reaches his physical limit, neither has any visible effects on his body. Shoto can easily counteract this weakness by alternating between ice and fire.
As part of his training, Shoto would sit in a barrel of water and alternate between ice and fire to regulate the water's temperature. This helped him become accustomed to the cold and better control the flames.
The development of his Quirk and mastery of his left side have allowed Shoto to combine his fire and ice into a "cold fire," using his circulatory system to move warm and cold blood throughout his body. This grants him immunity to damage from heat-based Quirks, as well as enhanced offensive capabilities, especially against those with such Quirks. However, this form of using his Quirk requires a certain level of concentration to maintain; otherwise, it will falter and dissipate. [29]

As seen before the war, Shoto wants to know more about him, such as what his favorite food is. He then rejects Dabi's statement that they are opposites who will never mix, saying that he will force their paths together, demonstrating that despite everything he has done, Shoto refuses to abandon his brother and longs to save him as well. During this, Shoto fully embraces his growth, realizing how much his friends at UA have helped him break free from his painful upbringing, thanking Class 1-A for reminding him that he is not alone.

To hide it. Having been denied a normal childhood so his father could train him to achieve his selfish ambitions, Shoto still bears various psychological scars, which tend to resurface when others compare him to Endeavor. Thanks to this and Izuku's influence, Shoto now strives to become a Hero, but without following the same path as his father. Shoto even tells Endeavor directly that he only intends to use him to improve and to stop the "loving father" nonsense in front of his friends, words that visibly affected Endeavor, who thought his son was finally opening up to him. Shoto remains relatively cold toward Endeavor and has made it clear that forgiving his past treatment of him and his mother is difficult, but he has also shown concern for his father's safety. Since Endeavor attempted to repair his relationship with his family, Shoto has adopted a cautious, yet hopeful, approach to this development. [9] 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, yelling at his father that he was looking at him, and then collapsing in relief in front of his classmates and teacher after seeing that Endeavor had survived. He also obtained permission to visit his home so he could see him, but once again turned his back on Endeavor while making a curt comment about his new scar. Unlike his brother Natsuo, Shoto does not seem to be opposed to the possibility of forgiving his father; however, he has made it clear to Endeavor that he must earn it. While pondering the matter, Izuku believes that Shoto is preparing himself to forgive his father and is waiting for the right moment to do so. During the Paranormal Liberation War, Shoto was deeply shocked and devastated to learn that Dabi of the League of Villains was his older brother.

Shoto once harbored a deep hatred for his fire abilities, which he inherited from Endeavor, as they symbolized his father's cruelty toward him and his mother, as well as what he was born to be: a tool to surpass All Might, a destiny he detested. As such, Shoto resolved to rely solely on his freezing power and never use the other half of his Quirk in battle (except to melt his ice), going so far as to cover his torso and left arm in ice in his first Hero Costume to symbolize his rebellion against his father. Shoto was often annoyed by Endeavor's mere presence and could barely contain his anger when speaking to him, especially when the Pro Hero mentioned the purpose he had for his son even before he was born. Ironically, Shoto's animosity toward his father made him more like Endeavor, apathetic and indifferent toward 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 UA Sports Festival, where he was forced to use his flames during the cavalry battle against Izuku Midoriya. Noticing Izuku's closeness to All Might, seeing that the two were somehow connected, and even initially believing that Izuku was All Might's illegitimate son, he sought to defeat Izuku 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 hateful gaze as Endeavor because his hatred fueled him, and Izuku realized that Shoto was unable to see beyond his resentment, his pain and anger preventing him from reaching his full potential. However, Shoto's resentment towards Endeavor has not yet disappeared, even though he respects his father's abilities as a Hero, admitting that such resentment doesn't vanish so easily and that he was wrong to try

Shoto originally had a cold and distant personality, stemming from his abusive childhood and complicated family life. Focused and unemotional, Shoto preferred to keep things to himself rather than spend time with others. However, after the events of the U.A. Sports Festival, Shoto became noticeably more sociable and friendly than ever, even developing a sense of humor and smiling occasionally, though he still retained some traces of his former aloof and nonchalant attitude. After the Provisional Hero License Course, he began to open up more to his classmates, and his usual seriousness has softened. However, Shoto is still not very used to socializing, and he seems a bit dim when trying to understand certain phrases and figures of speech (like when Camie Utsushimile asked for his phone number or when Mt. Lady tried to flirt with him) or when trying to read between the lines (like when he asked if Izuku Midoriya possibly also had two Quirks after using Blackwhip for the first time). Although he used to be quiet and reserved, Shoto initially possessed a moderate level of arrogance, which, combined with his solitary tendencies, sometimes caused him to take the initiative without considering the opinions of others, showing confidence that he could overcome any obstacle on his own. He used to be much more unfriendly as well, to the point that his cold attitude caused Inasa Yoarashi to hold a grudge against him without him even realizing it. Even in the present, Shoto seems to prefer acting alone, though he does so only for practical reasons, as it allows him to unleash his full power without worrying about friendly fire. Calm and composed, yet brutal in combat, Shoto has a strong foundation in the ethics of heroism, and only wishes to subdue his frozen opponents rather than kill them by prolonging the freezing.

During spring break, Shoto further improves his suit, which bears some visual similarities to his father's second suit. His wristbands now feature armor-like reinforcements and plates from his wrists to his knuckles, and can store heat and cold to condense his power (in the manga, they have straps and a slightly different color). His jacket, now more heat-resistant, features a large, bluish-gray T-shaped stripe, representing his family name, running from his waist to his armpits. His utility belt is entirely beige (in the manga, it has more red accents) and can now hold nine capsules, two of them in two larger containers strapped to his sides. [8] The suit also has a slightly darker shade of blue (in the manga, it's a much grayer color palette). This suit is known as the "Gamma Suit."

Shoto is a moderately tall and quite muscular young man, well-built for his age due to his intense childhood training. He has short hair that doesn't reach his neck, with bangs parted in the middle to avoid obstructing his vision. His hair is evenly divided between white on the right side and red on the left; this unusual coloring is due to his Quirk. As a result, although his eyes appear rather thin and reserved, he also possesses heterochromia iridum, which makes the iris of his left eye appear turquoise, while the iris of his right eye is dark gray. In addition, he has a large burn scar on the left side of his face, extending from his hairline to the middle of his cheek. He usually has a serious expression, but despite this, several of the girls in his class have stated that he is quite handsome, with Mina Ashido even going so far as to say that he is the most handsome boy in Class 1-A. [7 His updated hero costume consists of a dark blue, heat-resistant jacket with elbow-length sleeves, a high collar, and a built-in heating/cooling device, secured in the center by a gray strap. He wears baggy pants in the same color as the jacket, a tactical vest with a metal plate and red accents, which now functions as a heater and radiator, and white boots similar to those in his original costume, with studded soles and a thin, paler-dark gray center zipper. He also wears a beige belt with red accents around his waist, which can hold four small metal capsules containing medical supplies, two hanging from the front and two from the back. Later, in the Provisional Hero License Exam Arc, his costume gains two red, metal-coated wristbands, which help regulate his body temperature after his attacks, and his boots now have a set of straps across the top of the foot.

Shoto Todoroki(エアコンヒーロー ショート, Eakon Hīrō Shōto)轟とどろき焦しょう凍a, also known as the AC Hero: Shoto (エアコンヒーロー ショート, Eakon Hīrō Shōto), is the tritagonist of MyHeroAcademia. He was a student in Class 1-A at UA High School and one of the two to enter through official recommendations.[5] He is also the youngest son of Endeavor, the former number 2 and then number 1ProHero.

However, excessive use can result in Bakugo injuring his arms from the force of the long-range explosions.
Another drawback of Katsuki's Quirk is that he's unable to use his explosions in areas filled with flammable gas, as his explosions would ignite the gas and spread it even further. Furthermore, because his Quirk relies on his sweaty palms, it's more difficult for him to use it effectively in colder climates. Without the sweat on his palms, he can't utilize his Quirk to its full potential.

Explosion (Bakuha): Katsuki's Quirk allows him to secrete nitroglycerin through the sweat of his hands and detonate it at will to create explosions.[7] The more Bakugo sweats, the stronger his explosions become.[8] As noted by Best Jeanist, Katsuki has a strong understanding of his Quirk's applications.[9] He usually uses small, powerful explosions from his hands not only to blow up his opponents, but also to propel himself and move through the air, among other non-combat uses. He can maintain the sequence of his explosions long enough to destroy a giant ice wall created by Shoto.[10]
The explosions are powerful enough to send opponents flying with little 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 explosion to date (without the need for grenade gauntlets) was used to completely destroy Ochaco Uraraka's meteor shower, sending her flying away with the subsequent shockwave that shook the entire Sports Festival stadium.[13] He later uses it several times in succession when facing All Might in the physical test of the final exam. Katsuki suffers some impact from his explosions due to their magnitude, but the overall effect is minimal given his physical conditioning. He is able to trigger constant explosions around himself without feeling any negative repercussions, even after many powerful blasts. However, excessive use can result in Bakugo injuring his arms from the force of the powerful explosions.
Another drawback of 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 even further.

However, his 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.

At first, when he was defeated, he went into a kind of shock, and in addition to this, he does not admit that he surpasses others when the fight ends without him delivering the final blow, like when he fought against Ochaco Uraraka in the Sports Festival and they decided to end the confrontation before he finished Ochaco.
As the story has progressed, Katsuki's personality has gradually changed. Initially, he was very arrogant and intolerant, but little by little, he has softened his attitude to the point of implicitly showing concern for others, as demonstrated in the provisional hero license exam when he reduced his explosions to avoid harming Denki and Eijiro, or when he waited for Eijiro to return from the battle against the Eight Precepts of Death. He has also shown empathy, as seen in Shoto's case when he secretly listened to his past.

Katsuki presented himself as a very impulsive, aggressive, and arrogant person, as seen in the way he treated Izuku, whom he constantly violated physically and psychologically, even telling him to kill himself, showing his bastardly attitude.
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 demonstrated during the Trial Battle, when at the entrance of the academy, Izuku tried to explain to him that his Quirk One For All came from another person, and Katsuki interpreted that he was mocking him, so he tried to shut him up by saying that he simply beat him.[4]
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 the enclosed environment they were in. Despite this, and regardless of his lack of compassion, he has been recognized for his enormous talent and fighting prowess, as he not only attacks and destroys, but is also able to use his Quirk to move through the air. This has been noted by Momo Yaoyorozu, Shoto Todoroki,[5] and even All Might.[6] Although he isn't the hero with the best character, as the story progresses, his behavior slowly begins to mature, becoming less rude and arrogant. As the year goes on, he begins to trust and cooperate with his classmates, whom he previously rejected because he wanted to do everything on his own, neither helping nor expecting help. That egomania cost him several mistakes in class that led him to defeat or to be very close to it, were it not for the fact that he had to reluctantly cooperate with his classmates.
His inspiration to become a hero was the same as Izuku's, the symbol of peace All Might.

Katsuki is a young man of average height, with a lean, muscular build and fair skin. He has short, spiky, ash-blond hair with choppy bangs that hang over his eyebrows. His eyes are sharp and a 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 the ankles, even though he wears a belt.
His hero costume consists of a tight, black, muscle-hugging T-shirt with an orange "X" in the center, forming a V-neck. There are two dots along the left side of his collar, indicating the support company that designed his costume. His costume also features a metallic collar with rectangular ends, each with three holes. His sleeves extend from inside 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 wears knee-high black combat boots with orange soles and eyelets. His mask is jagged and black, and as it wraps around his eyes, a large, orange-rimmed flare protrudes from each side. His winter hero costume features a large jacket with a high collar instead of his usual tank top, though it has the same orange "X" design, allowing him to still sweat sufficiently—that's how his Quirk works.
During his internship with Best Jeanist, he wore a pair of tight blue jeans with his hero costume, instead of his usual baggy pants. His hair was also styled and parted to the side during this time.

Katsuki Bakugo(爆ばく豪ごう勝かつ己きBakugō Katsuki?)[2], also known as Kacchan(かっちゃんKatchan?) by his friends and by his hero name God of the Big Killing Explosion Dynamight(大だい•爆ばく•殺さつ•神しんダイナマイトDaibakusatsu-Shin Dainamaito?),
