|| Shoto Todoroki ||

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, and wears bangs, parted twice to avoid obscuring his vision.

His hair is evenly split between white on his right side and crimson red on his left, this unusual coloring being due to his Quirk. As another result, he also possesses heterochromia iridum, which causes his left eye's iris to appear turquoise, while his right is a brownish dark gray.

His eyes, in shape, are quite thin and reserved. 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. Despite this, he still gets called the most handsome hero.

Shoto originally had a cold, aloof personality, which stemmed from his abusive upbringing and complicated family life. Focused and unemotional, Shoto preferred to keep to himself instead of hanging out with others. After the events of the U.A. Sports Festival, however, Shoto notably became more sociable and kind, even gaining a sense of humor and occasionally smiling, although still retaining some fragments of his previous distant attitude. 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.

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, evidenced by when 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 only 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 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. 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. Upon first meeting him, Inasa noticed that Shoto had the same hate-filled glare that Endeavor had due to his hatred driving him while simultaneously holding him back from his full potential.

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 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.[6] 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.

Half-Cold Half-Hot (半はん冷れい半はん燃ねん Hanrei Han'nen?): Shoto's Quirk gives him the ability to generate ice from the right side of his body, and flames from his left side.

Due to years of rejecting his father, Shoto has developed a habit of favoring ice, even when fire would be a better option. This grudge also caused him to have difficulty controlling his flames. While he is capable of using both elements simultaneously, he isn't used to doing this and still needs to practice dual wielding. While training for his ultimate move, he claimed that using both abilities at the same time slows him down.

If he overuses one element without utilizing the other, then his own body temperature will suffer; the ice half will cause frostbite and the fire half will cause heatstroke. Until his bodily limit is reached, however, neither has any visible effect on his body. Shoto can easily negate this weakness by alternating between ice and fire.
