Shoto Todoroki²

Half Cold Half Hot (半はん冷れい半はん燃ねん Hanrei Hannen): Shoto's Quirk grants him the ability to freeze with the right half of his body and burn with the left. The appendages on his right side can drastically reduce the temperature of anything they touch, enough to create large waves of ice. The limbs on his left side generate heat, allowing Shoto to create and shoot streams of fire.

The drawback of his Quirk stems from his need to maintain his own body temperature, as excessive use of his ice power causes Shoto to suffer from frostbite. The frost covering his body physically slows him down and weakens the strength and speed of his ice attacks. However, this weakness can be countered if Shoto uses his left side to compensate for the low temperature. The side effect of prolonged use of his fire side has not yet been revealed, as he has never overused it.

As Stain pointed out, one of Shoto's biggest weaknesses is his heavy reliance on the devastating power of his Quirk. Another drawback is that Shoto can't fully control the fire and ice he generates. While he's capable of using both abilities simultaneously, he's stated that he's not used to doing so and still needs practice mastering his Quirk. Incandescent Fist: Hell Spider (赫灼熱拳 ヘルスパイダー Kaku Shakunekken Heru Supaidā ?) Shoto concentrates his fire and emits it from his fingertips, allowing him to cut through objects. He first uses this attack to destroy lasers at a Humarise base.

During the match between Momo Yaoyorozu and Itsuka's Kendo class teams, Shoto realizes that there is a flaw in Itsuka's strategy of caution in separating Momo from her teammates. He points out that if she truly wanted to be cautious with Momo, Itsuka would have overwhelmed her entire team from the start of the match. After witnessing Izuku's recent awakening of a second Quirk, Shoto deduces that this Quirk may be like him, but Shoto fails to recognize the true depth of Izuku's newfound power.

Shoto possesses tremendous power overall, but due to past decisions and circumstances, such as his intentional neglect of half of his Quirk, he has yet to reach his full potential. And while Shoto may have complete mastery over ice, his control over fire remains relatively inept, especially compared to Endeavor's.

Improved agility

Shoto is fast, agile, and has lightning-fast reflexes. He was able to maintain first place for most of the Obstacle Course during the sports festival thanks to his athletic prowess. He was also able to create walls of ice in a split second to prevent being knocked out of the ring during his battles with Izuku and Katsuki. He was also able to partially dodge a knife thrown at his face and several other attacks from Stain, a remarkably agile opponent.

Sharp intellect

Shoto has proven to be very intelligent. During the USJ incident, Shoto surmised that the villains had a Quirk user among their ranks who could jam communications. He realized that the attacking villains had some kind of agenda and interrogated some of them to get answers. Shoto's theory was correct, as the villain's goal was to kill All Might. Shoto deduced that Izuku had a connection to All Might after experiencing Izuku's power and witnessing All Might fighting Nomu. While he was right in deducing that Izuku had a connection to the hero, he incorrectly believed that Izuku might be the secret son of All Might from an affair. He was able to find out the location of Izuku, Tenya Iida, and Stain from an emergency call and arrive in time, though he complained that it took a while. Despite his training, Shoto is also very academically gifted, as he ranked fifth in the midterm exams.

Having been trained by his father from a young age, Shoto entered U.A. High School through recommendations and has established himself as one of the strongest students in Class 1-A. He placed second in both the Quirk Apprehension Test and the U.A. Sports Festival. Shoto also has great control over his versatile and powerful Quirk, which grants him incredible dual abilities.

Using the right side of his body, Shoto can drastically lower temperatures and freeze anything he touches. He can quickly freeze entire buildings and instantly create massive waves of ice. Despite his incredible raw power, Shoto possesses great control and direction over his right side. He can restrain the ice to avoid fatally freezing someone or use precision attacks to freeze only specific parts of a target's body. When fighting alongside others, he can blanket enemy territory in ice while simultaneously preventing it from hindering his allies.

Shoto is able to mold ice into various shapes for support, such as protective barriers, ladders for elevation, or a moving wave of ice for navigation. He also has numerous mobility options, such as stacking ice fragments behind his back to propel himself forward or freezing the ground to skate on. From the left side of his body, Shoto can drastically increase temperatures and unleash blazing flames. When he ignites these flames, the resulting fire engulfs his arm and the left side of his head. He can also fire consuming streams of fire or protective short bursts. After upgrading his suit to help him control his temperature, the flames only ignite in Shoto's hand, demonstrating greater control over his left side.

Shoto is a tall young man, measuring 1.76 and well built for his age, being 15 years old. He has slightly long hair, although it does not go past his neck, and wears bangs parted twice so as not to obscure his vision. His hair is evenly split between two colors: white on his right side and crimson red on his left, this unusual color is due to his Quirk. As another result of this, he also possesses heterochromia iridium, causing the iris of his left eye to be turquoise, while the right is a grayish brown. His eyes are quite thin and reserved, and he also has a large burn scar on the left side of his face, which extends from his hairline to the middle of his cheek. Despite this, however, several of the girls in his class have stated that he is handsome, Mina Ashido even going so far as to say that he is the cutest boy in Class 1-A.

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 he has shown concern for his father's safety. Now that Endeavor is trying to improve his relationship with his family, Shoto has adopted a cautious but hopeful approach to this development. Later, Shoto decides to do his internship with his father again, but also invites Izuku and Katsuki to train with him; ultimately, the three of them do their internships with Endeavor. This allows Shoto to greatly improve his teamwork, as well as to develop more precise control over his ice and fire quirk.

During his confrontation with Izuku Midoriya at the UA Sports Festival, Izuku's speech brought back memories of his mother's words of support, and for the first time since childhood, Shoto used his fire power in combat. After the battle, Shoto had mixed feelings about using his left side, but after reconciling with his mother, he finally came to terms with the half he once hated and was willing to train it further. Despite being scarred by her when he was a young child, Shoto shows no resentment towards his mother, visiting her often since the end of the Sports Festival. Shoto seems to derive 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.

Despite his difficult past, Shoto doesn't let his hatred for Endeavor completely cloud his judgment and still recognizes him for his skills and abilities as one of Japan's top heroes. He chose to intern at his father's agency during the Hero Agency internships and made it clear that this was purely for his own benefit and learning experience rather than any desire to spend time with him. Shoto reflects quite a bit on his own growth, realizing how much his perspective changed thanks to Izuku's words and how much better he became because of it. Because of this, Shoto wasn't against his father deciding to try and make amends with his family and become a better person, knowing from experience that one single thing can change a person if they allow it.

Although generally 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 face any obstacle with his own strength.

He used to be much more hostile, too, to the point of annoying people with his arrogant nature. Shoto preferred to act alone, though for practical purposes, as doing so allowed him to unleash his full power without having to worry about fire. Calm and composed, yet brutal in combat, Shoto is firmly grounded in the ethics of heroism; he only wishes to subdue his opponents by freezing them rather than killing them by prolonging the freezing process.

Shoto deeply detested his fire abilities that he inherited from Endeavor, as they symbolized his father's evil towards him and his mother, as well as what he was born to be: a tool to surpass All Might, a destiny he loathed.

As such, Shoto chose to rely solely on his ice power and never use the other half of his Quirk in battle, even going so far as to cover his left torso and 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 whenever the Pro Hero mentioned the purpose he had for his son from before birth. Ironically, however, Shoto's hostility toward his father made him more like him, becoming apathetic and indifferent toward others while obsessively focusing on his own goal of rejecting his father. Upon first meeting him, Inasa noticed that Shoto had the same hateful look in his eyes as Endeavor.
