Shoto Todoroki

Shouto Todoroki (轟焦凍) is a student at Yuuei training to become a Pro Hero. He got into Yuuei through a scholarship because of his powerful Quirk.

Appearance
Shouto has short, bicolored hair; the right side is white, the left side is red. He has a burn over his left eye. He possesses heterochromia which causes his eyes to be green on left side and black on right side.

In his initial hero costume, Shouto wears a simple white shirt, white pants, white boots, and gold-colored combat vest. He also has ice covering his left torso and arm.

In his new hero costume, Shouto wears a dark blue jacket, dark blue pants, silver-colored combat vest, and white boots. He also wore a silver-colored belt with metal capsules.

Personality
Shouto has a cold, aloof personality which stems from his harsh upbringing. Shouto appears to be quite seasoned as he battled a group of villains in a calm and composed manner, which indicates that he can be calm and collected. Though brutal in battle, he is well grounded on the ethics of heroism, only wishing to subdue his frozen opponents as opposed to killing them through prolonging their frozen states. After the first semester of Yuuei ends, Shouto still has a distant attitude but is not above socializing.

Shouto had a deep loathing for his fire power, as it symbolized his father's wickedness towards him and his mother as well as symbolized what he was born for; a tool to surpass All Might, a fate that Shouto detests. Shouto thought that by constantly using his fire power, he would become what his father wanted him to be (to surpass All Might, which Shouto doesn't want to do) and that he would become no different than his father (a heartless and selfish person), thus Shouto decided never to use his fire power in combat and only rely on his ice power, going so far as to cover his left torso and arm with ice whenever he appeared in his hero costume to symbolize his rebellion against his father and his fate. During his battle with Izuku in the Sports Festival, Izuku's words triggered his mother's words to him that he forgot; Shouto realized that he is not a slave to his bloodline and that his fire power is his own power belonging to him, not a power belonging to his father, therefore Shouto for the first time used his fire power in combat, deciding to become the Hero he wants to be (not what his father desires him to be). After his battle with Izuku, Shouto has shown to have mixed feelings about using his fire power, indicating that he has stopped loathing and rejecting his fire power to a certain degree. Shouto and his mother reconciled their relationship and after doing so, Shouto has come to terms with using his fire power, no longer loathing his fire side.

History
His father, Endeavor, was always overlooked by All Might and was always seen as the Number 2 hero of all time, regardless of his impressive crime solving records which are superior to any other hero. Because of this, wanting to surpass All Might out of obsession, Endeavor forced a Quirk Marriage onto Shouto's mother in order to conceive a Quirk-enhanced child capable of surpassing All Might and thus Shouto was born.

When he was five years old, Shouto started to receive training from his father. However, the training was harsh and detestable to the point that Shouto threw up. Shouto's mother tried to defend him, saying that he is too young, but Endeavor refused to listen. Endeavor also prevented Shouto from interacting with his older brothers. Shouto began to despise the training and hate his father for abusing his mother. During these dark times, Shouto's mother would always be there to support Shouto. She told Shouto that he is not a slave to his blood and he can become whatever he wants to be. However, Shouto's mother started to become insane from all the abuse received from Endeavor and after seeing Shouto's left side, threw boiling water over Shouto's face, causing a burn over his left eye.

After this incident, Shouto asked his father where his mother was, to which Endeavor replied that he sent her to the hospital much to Shouto's shock. Shouto blamed Endeavor, saying that everything was his fault. At some point, Shouto would forget about his mother's supportive words.

Battle Trial Arc
Shouto is teamed up with Mezou as part of the Heroes team against Mashirao and Tooru as the Villains team. He is informed by Mezou of the Villains' positions and instructs Mezou to go outside of the building. Shouto freezes the entire building and then suddenly appears on the floor where the core is. He says to Mashirao that he can take a step forward but warns him of the consequences of doing so as the floor is heated up by his doing. Shouto then casually goes to touch the core due to Mashirao not being able to move, allowing him and Mezou to win.

Ultimate Space & Jams Arc
When the Villains invaded the Ultimate Space and Jams, Shouto surmises that the villains have a Quirk user who has the ability to prevent sensors from going off. After taking the area they are in and his class's schedule into account, Shouto deduces that the villains have an objective, saying it isn't an ambush without a carefully planned scheme behind it. He tries to evacuate with his class, but his attempt to is intervened by Black Mist and is warped to the landslide area of the U.S.J where he is confronted by a group of villains. He asks the villains whether they have mercy for kids and begins to fight. Shouto quickly defeats all the villains in the area, sarcastically remarking on the villains' mission to scatter and kill them as well as comments on their inability to effectively wield their Quirks. Because the villains are unable to do anything due to being completely frozen by Shouto, he states that they will die if they stay frozen, and decides to take the opportunity and asks the villains why they want to kill All Might.

Shouto then appears during All Might's fight with Noumu, Black Mist, and Shigaraki Tomura, freezing half of Noumu's body which, along with Katsuki's attack on Black Mist, frees All Might from Noumu. He then says that he heard about each of the villains' roles in killing All Might, but says that the Symbol of Peace won't go down so easily. Shouto then watches All Might's fight with Noumu. He is then seen with his class after the battle with the Villain Alliance is over.

Sports Festival Arc
Shouto is seen in class listening to Shouta Aizawa's announcement about the Yuuei Sports Festival approaching. In the lunchroom, Shouto overhears Ochako Uraraka and Tenya IIda's conversation about All Might and Izuku Midoriya having similar Quirks, which grabs his interest. As Class 1-A prepares to enter the Sports Festival, Shouto approaches Izuku and tells him that objectively, he is stronger than Izuku. He then says that All Might has a deep interest in him and says that he doesn't care why. Shouto then states that he will defeat Izuku. Izuku admits that he is definitely strong and could beat more than half the people in their class, but states to him that everyone are giving it their all, hoping to be the best and that he will also give it his all, intriguing Shouto. When the Obstacle Race begins, Shouto freezes the ground and skids into first place as well as hindering everyone else due to freezing their feet. However, several of his classmates manage to avoid having themselves stuck in his ice, causing him to comment that he might have underestimated them. Minoru tries to attack Shouto, but he is attacked by a robot before he could.

When, Robo Infernos appear blocking Shouto's path. Shouto freezes the robots, saying to himself that the Yuuei staff could have thrown something tougher in his way as his "shitty old man" is watching. Shouto runs on ahead, warning the others behind him that he froze the robots in a dangerous position and thus will crash down, which causes a blockade and stops the others while Shouto forges ahead.

Shouto manages to get across the Fall easily while still keeping the lead. He then reaches the final leg of the race which is a land mine field. Shouto treads carefully, realizing that it is meant to be a disadvantage for the person in the lead. Suddenly, Katsuki Bakugou blasts himself towards Shouto with his Quirk and asks him whether he issued his war declaration to the wrong rival. Soon, both Shouto and Katsuki get into a brief scuffle. Shouto then watches Izuku flying towards him and Katsuki. Izuku manages to pass them, but Shouto manages to catch up to him, but before he does, Izuku uses his metal plate to blow dust in his eyes, causing him to stop momentarily, allowing Izuku to place first. Shouto then crosses the finish line placing second,  thus allowing him to continue on to the next event, the Human Cavalry Battle. Shouto then teams up with Tenya Iida, Momo Yaoyorozu and Denki Kaminari for the Human Cavalry Battle. Shouto explains to his team mates that the reason he chose them is because their Quirks would give them the best balanced battle formation. He then goes on to explain the battle formation: Denki will be on the left, sending out sparks so that other teams don't get too close to them; Momo will be on the right and will use her Quirk to make an insulator sheet along with whatever else she can create that can provide defense and mobility and Tenya will be in the front using his Quirk to be their physical defense. When asked whether he can feint attacks using his Fire and Ice Quirk, Shouto states that while in combat, he will never ever use his fire power, which seems to anger his father, who is watching from the bleachers. After the Human Cavalry Battle begins, Shouto and his teammates confront Izuku and his team.

Shouto orders Momo to prepare an insulator sheet and tells Denki to prepare to release his electricity. Shouto covers himself along with Momo and Tenya with the insulator sheet while Denki releases a huge amount of electricity, electrocuting and stunning the other teams attacking them. Afterwards, Shouto immobilizes the stunned teams by freezing their legs. Shouto takes one of the headbands of the teams while charging forward to fight Izuku's team. Fumikage's Dark Shadow tries to attack Shouto but Momo uses her Quirk to block the Dark Shadow. Shouto's team continues fighting, but Izuku's team proves to be quite resilient. Shouto ponders that Izuku has figured his weak spot and tries to think of a plan. With only a minute left, Tenya tells his team to hold on tight as he uses his move Recipro Burst to forcibly accelerate his movement to blazing speeds allowing him and his team to speed past their enemies in a blink of an eye which catches Izuku's team off guard and allows Shouto to grab Izuku's 10 million headband in the confusion.

Shouto then sees that Izuku is going to attack him with full force. Knowing that the danger is high, Shouto has no choice but to use his Fire power to confront Izuku's might, setting his left arm alight with fire and prepares to fight Izuku for the final minute of the Human Cavalry Battle. Shouto's left arm is knocked away by the wind pressure Izuku created. Shouto then realizes that he is using his fire power and is shocked by what he is doing after stating that he would never use it in combat. Shouto lets his guard down due to being shocked by his own actions, allowing Izuku to take a headband from Shouto, with Shouto remaining silent. However, Izuku did not take the ten million point headband but another one. Tenya tells Shouto to pull himself together which snaps Shouto back to reality. For the last ten seconds, Shouto's team prepares to attack Izuku's team with Shouto creating a stick of ice to combat Izuku, but the Human Cavalry Battle ends before he does so. Shouto's team places first, allowing him and his team to participate in the final event. Shouto is angry with himself for using his fire power, saying he cannot go on like this. After the lunch break begins, Shouto meets Izuku in private, wanting to tell him something. Shouto says that Izuku made him broke his pledge; that he would never use his fire power. After facing him in combat, Shouto assumes that Izuku is All Might's illegitimate son, but Izuku says that is not what his relation to All Might is. After hearing this, Shouto concludes that Izuku has some connection to All Might. He then says that Izuku should know about his father, Endeavor who has been the number two hero forever and if Izuku is connected to All Might, the number one hero, he has all the more reason to win against Izuku. Shouto then explains his reason why he must win against Izuku; his father wanted to advance his position above All Might but could never do it with his own power and devised a plan; a Quirk Marriage that would allow him to get a child with an enhanced Quirk and raise that child to rise above All Might. Shouto then says that he will never be his tool. Shouto then goes on to explain some of his past; that his mother despised his left side and dumped boiling water on him. Shouto explains that the reason he must beat Izuku (someone who is connected to All Might) is a personal triumph over his father, saying that he will become the number one hero without using his father's Quirk and that it would be his total disavowal of him. Shouto then walks away, saying that he will climb over him using his ice powers. Izuku then states that he cannot lose either and that he will take Shouto's war declaration and echo it; saying that he will beat him.

The final event is a tournament event and Shouto's opponent in the first round is Hanta Sero. Seeing that his second round opponent would most likely be Izuku, Shouto expresses surprise to face him so soon, but says that he will defeat him with his own hands. During the recreational events, Shouto is seen outside thinking to himself.

As Shouto walks to the ring for his fight, Shouto encounters his father, to which Shouto tells him to get out of the way. Endeavor states to his son that his behavior is disgraceful and comments that if he had used his fire power, he could have crushed the Obstacle Race and the Human Cavalry Battle events.

Endeavor goes on to say that his resistance is childish and tiresome, telling him to stop fooling around and see to his duty to surpass All Might. Endeavor says that he is different than his older brothers and that he is his greatest masterpiece. Endeavor's talking enrages Shouto. Shouto speaks up, wondering if his talk about surpassing All Might is all he ever has to say. Shouto declares to his father that he will only use his mother's ice power to win his victories and will never use his fire power in any battle. Endeavor comments that even if his tactic works for now in high school, he will eventually reach a point soon enough where he will have to rely on his fire power, which infuriates Shouto. Shouto walks into the ring to meet his opponent; Hanta. After the battle begins, Hanta wraps tape around Shouto, attempting to throw him out of the ring.

Shouto (who is still furious about his father's speech a bit earlier) fiercely retaliates by using Giant Ice Ridge, a humongous pillar of ice that freezes most of Hanta's body and in the process, freezes and shatters Hanta's tape, freeing Shouto. Hanta says that he is unable to move and as a result, because he is unable to do anything due to being trapped by Shouto's ice, is declared defeated and Shouto is declared the winner, thus moving on to the next round.

Shouto goes to the immobilized Hanta and apologizes for overdoing it, saying that he was just aggravated. Shouto then uses his fire to melt the ice off Hanta.

Shortly after Eijirou and Tetsutetsu's arm wrestling game, Shouto walks into the ring to meet his second round opponent which is Izuku. After Izuku arrives, the match begins and Shouto prepares to charge. Shouto strikes first, sending a wave of ice towards Izuku. Izuku counters by sending a great amount of wind pressure, destroying the incoming ice and knocking Shouto back a bit. Shouto is hit again by Izuku's wind pressure but Shouto is pushed into the ice behind him that he set up as a precaution to prevent himself from being blown out of the ring which successfully works. Shouto sends another wave of ice against Izuku and starts running towards Izuku. Izuku destroys the ice again but Shouto continues to close on Izuku. Shouto runs onto his ice, jumps off it, goes into the air and lands down onto the ground, knocking Izuku back and at the same time sends ice towards Izuku which freezes his foot. Seeing that Izuku is trapped, Shouto decides to attack Izuku. However, Izuku strikes back by sending a huge blast of wind pressure against Shouto which knocks Shouto back with force but Shouto once again creates ice behind him to prevent himself from being blown out of the ring. Shouto then says that Izuku has reached his limit and just as he thought the pros who are watching can now see that he is more than just the 'son of No. 2'. Shouto then says that Izuku shouldn't fight with the way his hands are and decides to end the fight, sending a wave of ice towards Izuku. However, Izuku sends a blast of wind pressure, destroying the incoming ice and knocking back a surprised Shouto. Izuku states that Shouto has a limit to how much generated cold he can take, but he can use his left side to solve that problem. Izuku criticizes Shouto for declaring that he would win using only half of his power but hasn't even landed a single scratch on him with that half power. Izuku then demands that Shouto goes to him and fights him face to face. Shouto, now angry, wonders what Izuku is planning.

Shouto then thinks that his father paid Izuku to go all out against him. Enraged, Shouto charges towards Izuku. However, as he gets close to Izuku, Shouto starts to experience the frostbite from using his ice power too much and his movements become sloppy, which stops him from evading properly. This causes Shouto to get hit in the stomach by Izuku's One For All enhanced punch, knocking Shouto down onto the floor and becomes injured. However, Shouto gets back up and launches a wave of ice at Izuku but it is weaker than before. Izuku destroys the ice attack with a blast of wind pressure and knocks Shouto back. Shouto asks Izuku why he is going so far, to which Izuku replies that he wants to live up to his mentor's expectations and wants to become an awesome hero who can answer people with a smile. Shouto is hit by Izuku again who states that while he may never understand Shouto's circumstances and resolution, he thinks that becoming Number One without using his full strength and doing it to disown someone is a joke which causes Shouto to tell Izuku to shut it. Shouto starts remembering his miserable past about how his father was abusive towards him and his mother. Meanwhile, Shouto begins to experience the full effect of his frostbite, causing icy marks to appear over his right side. Shouto, unable to move properly, is hit by Izuku again. Shouto remembers the incident of where his mother threw boiling water over his face. As Shouto gets up, Izuku tells Shouto that his fire power belongs to him and only him. After Izuku says these words, Shouto finally remembers what his mother said to him in the past; that he isn't a slave to his bloodline and can become whatever he wants to be. Touched by his mother's words and moved by Izuku's words, Shouto decides to activate his fire power, setting the left side of his body ablaze, telling Izuku that he wants to become a hero as well and smiles.

Shouto asks what Izuku is smiling about, noting that with grievous wounds like those he is crazy. Shouto powers up for one final attack and sends a great wave of ice towards Izuku. Even though Cementoss intervenes by creating cement pillars to block off his path, Shouto presses on and after thanking Izuku to himself, he ignites the cold (generated by his wave of ice) with his fire power to create a huge wind blast which, along with Izuku's wind pressure attack, creates a huge shock wave which blasts both of them back.

After the dust and smoke clears up, Shouto is seen standing in the ring without any injuries and sees that Izuku is out of bounds. Shouto is declared the winner and advances to the third round.

Shouto leaves the ring and encounters his father in the corridor. Endeavor tells Shouto that he is proud of him for accepting to use his fire power and that he has become the perfect upgrade of him. He goes on to say that after he graduates, he will let Shouto become his sidekick. However, Shouto tells Endeavor that he cannot change so easily and hasn't rescinded his disavowal of him. Shouto then says the only reason he used his fire power was because for a split second he completely forgot about him (Endeavor). As he walks away, Shouto says that he needs to contemplate about his fire power. Shouto gets a new gym shirt to replace the damaged one and, afterwards, walks into the stadium.

Shouto faces his opponent, Tenya, in his third round match. After the match begins, Shouto attacks first with a wave of ice but Tenya dodges the ice by jumping towards Shouto. Tenya uses Recipro Burst and tries to attack Shouto with a speed-enhanced kick, but Shouto dodges his kick. Tenya quickly counters and attacks Shouto with another speed-enhanced kick, slamming Shouto down onto the ground and becomes injured. However, Shouto retaliates by grabbing Tenya leg, but Tenya kicks Shouto away. Tenya grabs Shouto and proceeds to try and throw Shouto out of bounds before Recipro Burst ends. However, along the way, Tenya realizes that there is ice in his mufflers and he slows down. Shouto tells Tenya that he put ice in his mufflers when he grabbed his leg and freezes Tenya's entire body. Due to being unable to move, Tenya is declared defeated and Shouto advances to the final round of the tournament event. While walking away, Shouto admits to Tenya that he could not fully evade his Recipro Burst and says that he expected no less from it.

Shouto waits in the waiting room for his final match to begin. Shouto thinks about Izuku's words; that his powers are his and only his. Shouto admits that he didn't think that way before he fought Izuku. The door slams open, revealing Katsuki, who barged into the wrong room. Shouto doesn't take attention to Katsuki, much to Katsuki's annoyance. Katsuki complains about Shouto's attitude towards a fellow finalist. Shouto continues to ignore him until Katsuki uses a small Explosion on the table to get his attention. Shouto says to Katsuki that Izuku is the type of person who is compelled to drag out peoples' problems and help them. Shouto asks Katsuki, as Izuku's childhood friend, if Izuku has always been the type of person compelled to help people's problems. However, Katsuki angrily kicks the table over, telling Shouto that he doesn't care about Izuku and doesn't care about Shouto's problems or feelings. Before he leaves, Katsuki tells Shouto to give everything he's got.

Shouto goes to the ring and faces his opponent, Katsuki, in the final match. Shouto attacks Katsuki with Giant Ice Ridge, hoping to end the fight quickly. However, Katsuki thaws himself out with a defensive Explosion. After breaking out of Shouto's ice, Katsuki uses some Explosions to somersault himself into the air. While in the air, Katsuki grabs Shouto's hair and shirt and throws Shouto onto the ground, but Shouto creates an ice wall behind himself to prevent himself from being thrown out of the ring. Shouto is attacked again by Katsuki but he dodges Katsuki's Explosion and grabs Katsuki's arm. Shouto throws Katsuki into his ice wall and in the process throws himself out of harm's way. Katsuki becomes angry at Shouto for not using his full power, telling Shouto to not stand in front of him if he is not fighting to win. As Katsuki prepares his next attack, Shouto is in deep thought of whether to use his fire power or not; having trouble on deciding if it is the right choice to use it or not. Shouto admits to himself that since fighting Izuku he is struggling on what to do and how he should proceed. Shouto is confused and conflicted from his deep thinking. After Izuku yells at Shouto to keep fighting, Shouto decides to get his head in the game and activates his fire power. After activating his fire power, Shouto remembers his mother's reaction to his fire power and becomes disheartened. Shouto is hit by Katsuki's Howitzer Impact. After the smoke clears, Shouto is out of bounds, seemingly knocked out. A furious Katsuki walks to Shouto and grabs him by his shirt, dissatisfied with Shouto's performance, but Katsuki is knocked out by Midnight's perfume before he can do anything to Shouto. Because he went out of bounds, Shouto loses.

Shouto later appears at the closing ceremony of Yuuei's Sports Festival waiting on the podium to receive his award for second place. All Might gives Shouto his medal and congratulates him. All Might says to Shouto that he had his reasons for suppressing his fire power in the final match. Shouto replies to All Might that ever since his fight with Izuku he has been confused at what to do about his problems. Shouto says that he now realizes that he has not handled his problems properly due to trying to solve them by himself and that he must come to terms with things in order to solve his problems. All Might gives Shouto a congratulatory hug, telling Shouto he won't pry any further and that he knows now that Shouto can come to terms with anything that is troubling him.

After the closing ceremony of Yuuei's Sports Festival is finished, Shouto along with his class are given two off days. The next day, Shouto decides to go and see his mother who is in the hospital. Shouto's older sister, Fuyumi, is surprised that Shouto is going to see their mother after such a long time and asks Shouto why he is going, but Shouto does not reply to her. At the hospital, Shouto arrives at the door to his mother's room. Shouto believes that the only way to solve his problems and move forward (coming to terms with using his fire side and overcoming his trauma from childhood) is to meet his mother and talk to her. Shouto takes a deep exhale and enters his mother's room. Shouto's mother apologizes to Shouto and forgives him, smiling at her son through tears.

Field Training Arc
Two days after the Sports Festival, Shouto is in class. During the Hero Informatics period, Shouta reveals the Pro Hero nominations. Shouto received 4,123 Pro Hero nominations and is the highest amount of nominations out of Class 1-A. Momo comments to Shouto that his amount of nominations was to be expected, to which Shouto replies that most of his nominations were due to his father. Afterwards, Class 1-A has to decide on Hero names. Shouto, however, simply writes down and shows his own name to his classmates instead of coming up with a Hero name.

After Class 1-A is finished formulating their Hero names, Shouto is given his personalized work place list in order to choose a work place that he wants to train at. On his list, Shouto sees his father's work place as one of his work place choices and chooses his father's work place to gain workplace training. On the day of the work place training, Shouto is at the train station with his class so that he can travel to the work place of his choice by train.

Shouto is in Hosu with his father. He receives a text message on his cellphone from Izuku that asks for help. Shouto goes to Izuku's location. He arrives and sees that Stain is about to kill Tenya. Shouto launches a column of fire and a column of ice at Stain, forcing Stain to dodge Shouto's attack of fire and ice. Shouto reveals himself, telling Izuku that he texted him more information than usual and, as a result, he is late. Shouto tells Izuku that he figured out his text message and came running to save him.

Shouto begins his battle with Stain; Shouto attacks Stain with ice but Stain dodges. Shouto launches a stream of fire at Stain only to be dodged. Shouto's attacks of ice and fire manage to bring Izuku and the injured Pro Hero to him; Shouto states to Stain that he won't let him kill them. Izuku warns Shouto not to let Stain draw his blood. Stain throws his dagger at Shouto's face and manages to land a cut on Shouto's face; Stain appears before Shouto and attacks him with his dagger, but Shouto blocks Stain's attack with a pillar of ice. Shouto looks up in the air and sees Stain's katana, becoming distracted. Stain grabs the distracted Shouto and prepares to lick the blood off his face. However, Shouto activates his fire power and knocks Stain back, preventing the Hero Killer from ingesting Shouto's blood. Shouto attacks Stain with ice again, but the Hero Killer dodges and slashes at Shouto with his katana and dagger, although Shouto is able to defend himself with a small wall of ice.

Tenya begs Shouto to stop fighting as this is his fight, causing Shouto to criticize Tenya for seeking revenge, saying the Ingenium he knows would not make a face like his. Shouto creates and attacks Stain with great pillars of ice, attempting to block Stain's view. Stain cuts through Shouto's ice pillars with ease. Stain throws two small daggers into Shouto's left arm, causing it to bleed. Stain jumps into the air and prepares to stab Shouto with his katana. Suddenly, Izuku appears before him and grabs Stain, attempting to throw him onto the ground. The Hero Killer retaliates by knocking Izuku away with his elbow, causing Izuku to fall onto the ground. Stain then distances himself away from Shouto and Izuku. Shouto tells Izuku that avoiding close quarters combat and holding out is their best course of action against Stain with Izuku agreeing with him, telling Shouto that he will draw Stain's attention while he acts as support. Shouto states that they will protect Tenya and the Pro Hero. Izuku and Shouto team up to battle Stain. Izuku tries to attack the Hero Killer, but Stain slashes at Izuku with his katana, causing Izuku's leg to bleed; Stain licks his katana and activates his Quirk, which paralyzes Izuku. Now that Izuku is immobilized, Stain sets his sight on Shouto; he cuts through Shouto's wall of ice, removing Shouto's defense and prepares to attack Shouto. Shouto encourages Tenya to be the man he set out to be.

Shouto attacks Stain with a stream of ice and concealed within it is fire, but Stain dodges. Stain is about to cut through Shouto with his katana, telling Shouto that he relies too heavily on his Quirk. Suddenly, Tenya uses Recipro Burst and breaks Stain's katana in half with an enhanced kick, thus saving Shouto. After Stain tells Tenya that he is a fake Hero, Shouto informs Tenya to pay no heed to Stain. Shouto attacks Stain with a stream of fire and keeps him at bay. Shouto analyzes Stain, concluding that he is not as powerful as one might seem and that fighting against groups is his biggest disadvantage. Tenya tells Shouto to cool down his leg due to the effects of Recipro Burst. Stain attacks Shouto with daggers, but Tenya intercepts his efforts. Shouto cools down Tenya's leg enough for him to regain mobility. Shouto encourages Izuku and Tenya to press on with their attacks and the duo hit Stain with and enhanced punch and kick respectively.

Stain makes one last ditch attempt to kill Tenya, but Tenya retaliates with a kick and Shouto shoots a stream of fire at Stain's face, burning Stain's face. Tenya and Shouto's additional attacks finally cause Stain to lose consciousness, defeating him. Tenya and Izuku land safely onto the ground thanks to Shouto's ice ramp. Shouto decides to tie up Stain with Izuku suggesting that they remove Stain's weapons.

Izuku, Shouto, Tenya and the Pro Hero leave the alley with the unconscious restrained Stain in tow. Tenya offers to pull Stain, but Shouto tells Tenya that his arm is in bad shape. After Gran Torino and Endeavor's sidekicks arrive, Tenya apologizes for his un-heroic actions with Izuku saying that he is also sorry for overlooking his pain; Shouto tells Tenya to pull himself together because he is the Class President with Tenya complying. Out of the blue, the winged Noumu-like creature grabs Izuku; suddenly, Stain wakes up and defeats the winged Noumu-like creature while saving Izuku in the process.

After Endeavor arrives, Izuku tries to break away from Stain. Stain's bandaged mask falls off and reveals his true face, shocking Shouto. Stain walks forward and declares that the only one who is allowed to kill him is All Might, unleashing a bloody malefic aura in the process. Shouto falls down onto the ground out of fear. After Stain loses consciousness for the last time; Shouto is shocked and speechless that Stain is still standing despite being unconscious. Shouto along with Izuku and Tenya are taken to the Hosu General Hospital to have their wounds treated.

The next day at Hosu General Hospital, the recuperating Izuku states to Shouto and Tenya that it is a miracle that they are still alive as Stain could probably have killed him if he wanted to which Shouto agrees. Shouto praises Tenya for standing up against the Hero Killer but Tenya admits that he doesn't deserve praise. The Chief of Hosu Police, Tsurugamae Kenji arrives and tells Izuku, Shouto and Tenya that the Hero Killer is undergoing treatment. Tsurugamae states that Izuku, Shouto and Tenya acted on their own without the supervision of their superiors and as such violated the rules, thus they along with their superiors (Gran Torino, Endeavor and Manuel due to their negligence) will be given punishment. Shouto becomes furious that Tsurugamae expected them to follow the rules and let people die as a result, saying that Heroes saving people is their job. Tsurugamae comments on Shouto's behavior, saying that his education from Yuuei and his father are hatching well Izuku, Gran Torino and Tenya stop Shouto. However, Tsurugamae states that there were limited witnesses and as a result there will not be any punishment for Izuku, Shouto and Tenya but they won't be receiving any praise either from the public as the events that occurred yesterday will be covered up. Shouto, Izuku and Tenya thank the Chief of Hosu Police for not punishing them. Tsurugamae states that Izuku along with Shouto and Tenya have a promising future and thanks them for their heroic actions.

The next day where the newspapers and other medias publish Stain's defeat, Izuku and Tenya discuss their hand injuries and decide to become stronger. Shouto apologizes to which Izuku asks why; Shouto states that whenever he is involved, people's hands go bad. Izuku and Tenya are surprised that even Shouto can crack a joke but Shouto replies that he is serious, causing the three young Heroes to laugh.

The workplace training comes to an end and Shouto returns to Yuuei. During Foundational Hero Studies, Shouto watches the first group race through the construction site. Shouto sees Izuku's speedy movements and wonders who's movements they resemble.

End of Term Test Arc
One week before the end of term test, Shouto remarks that if he had just attended classes normally then Denki would not have such low grades, to which Denki asks Shouto to mind his words. In the lunchroom, Izuku, Tenya, Shouto, Ochako, Tsuyu and Tooru eat at a table, discussing about how they will perform in the end of term test. Back in class, Katsuki declares that he will defeat not only Izuku but Shouto as well before storming off. On the day of the exercise test, Mr Principal reveals that Class 1-A will be fighting against Yuuei's teachers in their exercise test. Shouto is paired with Momo and they must face Shouta Aizawa in their exercise test.

Shouto, Momo and Shouta arrive in an uninhabited city where their test exercise will take place. In the city, Shouta explains the test; Shouto and Momo must, in 30 minutes, either handcuff him or one of them must escape the battlefield in order to win and pass the test. The test begins. Shouto asks Momo to create random objects in order to distract Shouta because the test depends on who finds who first. Shouto informs Momo of their plan; he will fight Shouta while Momo makes an escape. Shouto tells Momo not to get separated until then.

Momo is creating Russian dolls and informs Shouto what she is creating. Momo is impressed with Shouto for being able to not only think of a strategy against Shouta but also have the judgement to make quick decisions on the best course of action. Shouto tells Momo that its normal; Momo admits that even though she is a recommended freshmen she is the only one that hasn't shown any noteworthy results.

Suddenly, Shouto realizes that Shouta is nearby, causing Momo to apologize for talking too much. Out of the blue, Shouta appears from above, hanging from telephone wires. Shouta comes down and Shouto leaps into action, trying to attack Shouta but misses. Shouto orders Momo to run away to which she does. Shouta wraps his bandages around Shouto and then hangs him from telephone wires, tying Shouto's bonds to a telephone pole. Shouta admits that he had always planned on capturing Shouto. However, Shouto points out his teacher's flaw, that he can break free from his bonds by using fire or ice. Shouta tells Shouto that he can break free but warns him to watch out when he drops; Shouta throws caltrops (spikes) underneath Shouto to act as a deterrent for Shouto. Shouto compliments his teacher for a nasty counter. Shouta tells Shouto that his strategy's responsibility is lopsided, commending him for giving Momo consideration but points out that he should have discussed his strategy with her a little more.

Momo is running away from the battlefield. While running, Momo is conflicted and confused on what course of action to take and is unable to decide if escaping is the best option or going back to help Shouto. Shouta appears in the air and launches a bandage at Momo which wraps around her arm. Momo tries to break free; she realizes that her Quirk hasn't been erased. Momo creates a bracelet from her bandaged arm, allowing her to break free; Momo continues to run. Shouta notes that Momo keeps comparing herself to Shouto because he has what she lacks; confidence.

Shouto is still hanging from the telephone wires, thinking about what Shouta said. Suddenly, Momo appears and apologizes to Shouto. Momo is unable to decide what to do; rescue Shouto or escape. Shouto apologizes to Momo for not taking her ideas into consideration and sees that Momo has something in mind. Momo says she does but it wouldn't work if Shouto's plan fell flat. Shouto encourages Momo to put her plan into action, telling her that he voted for her during the Class President election. Shouto's encouragement fills Momo with confidence; Shouta appears above Momo, preparing to attack her. Momo tells Shouto to close his eyes and she throws up into the air the Russian dolls she created. The Russian dolls open up to reveal flash grenades in them; the flash grenades create a brilliant light that causes Shouta to avert his eyes, preventing him from advancing and using his Quirk at the same time. While Shouta is distracted by the light, Momo releases and frees Shouto from the telephone wires; Shouto lands safely onto the ground. The confident Momo declares to Shouto that she does have a plan to prevail over their opponent; Shouta smirks.

Momo declares to Shouto that she thought of her plan from the start. Shouta jumps onto a rooftop for safety. Not wanting them to get the upperhand from his lapses of inactivity, Shouta launches cloth against Shouto and Momo. Momo and Shouto avoid Shouta's attack and Shouto counters by trying to use fire; however, Shouta erases Shouto's Quirk. Momo tells Shouto that they must hide for now and escape from Shouta's line of sight. Momo and Shouto begin retreating with Shouta not too far behind. Momo explains to Shouto that for her plan to succeed they need time, asking Shouto to keep confirming if he can use his ice side because she wants Shouto to unleash his huge ice glacier attack like at the Sports Festival against Shouto. Shouta is about to catch up, however, Shouto sees that Shouta is about to blink; Shouto uses Giant Ice Ridge, creating a humongous ice pillar that completely eclipses Shouta. Unable to see anything due to Shouto's Giant Ice Ridge, Shouta stands by.

Momo uses this opportunity to create Shouta's Capturing Weapon, except that it is not made of the same material like the Capturing Weapon. After creating a catapult, Momo explains her plan to Shouto to which he has no complaints. Shouta is still on stand by, thinking what to do next. Suddenly, Momo and Shouto run while cloaked. Shouta attacks the concealed Momo and Shouto with his capturing weapon. However, it is revealed that what Shouta captured was a mannequin Momo was holding. Shouta jumps away while Momo fires her catapult, launching her Capturing Weapon at Shouta which surrounds him. Momo then orders Shouto to shoot heat along the ground which he does. Momo asks Shouta if he knows what nitinol alloy is; it is an alloy that returns to its original shape when exposed to heat. Momo explains that the Capturing Weapon that she launched in the air which now surrounds him is made of nitinol alloy. Shouto's fire attack causes Momo's Capturing Weapon to wrap itself around Shouta, binding him. Afterwards, Momo and Shouto handcuff Shouta, which allows them to pass the practical test.

Shouto notices the ease of Momo's plan, to which Momo says that it wasn't easy because she slipped up when firing the catapult, which would have allowed Shouta to prevent her from going through with her plan. Momo asks Shouta if he was deliberately making it seem that he was caught by their trap; Shouta explains that he didn't and because he couldn't see Shouto he could not decide if he was going to use fire or ice and decided to retreat. Shouto concludes that Momo's plan came down to time after all; Shouto thanks Momo for making the plan prevail. Momo is happy that her plan prevailed and is about to cry tears of joys; Shouto wonders what is wrong and advises Momo that there is a pressure point on top of her foot to ease any pain, to which Momo tells Shouto that nothing is wrong and rubs her eyes.

In class, Shouto learns that he has passed the written test and will go to the forest lodge along with the rest of his classmates. After Class 1-A decide to go shopping to buy necessities for the forest lodge trip (which will be a boot camp), Shouto decides to go and see his mother in the hospital instead of going shopping because his free days from school are the only times he can visit her.

School Trip Arc
The next day after the shopping trip at Yuuei, Shouta informs Class 1-A that the destination for their lodge trip has been changed and the new destination will only be announced on the day of the event. The first semester has come to a close and summer break has begun. On the day of the event, Class 1-A boards a bus that will take them to the forest lodge destination. An hour later, Class 1-A’s bus stops for a restroom break. However, Class 1-A notes that Class 1-B isn’t at the rest stop. Suddenly, two females wearing cat-like costumes and a small boy appear; the females excitedly introduce themselves as the professional Hero Team, The Pussycats. The black haired female explains to Class 1-A that they will be staying at the base of a mountain which is a part of their domain; they have three hours to reach the base of the mountain using their Quirks as they please and those who don’t arrive there by 12:30 pm won’t be served lunch. Soon, Class 1-A realize that they have already arrived at their destination and their training camp has already begun with the Pussycats being their supervisors. Some of Class 1-A try to leave, but Pixiebob uses her Quirk to create a landslide of dirt that causes Class 1-A to fall into a forest called Forest of Magic Beasts, which they must traverse to reach their destination. Suddenly, Class 1-A are confronted by a beast; Kouji tries using his Quirk to control the beast but it does not work due to the beast being made out of dirt. Shouto along with Katsuki, Tenya and Izuku mobilize and use their Quirks to destroy the dirt beast.

After Izuku, Tenya, Shouto and Katsuki destroy the dirt beast, Class 1-A begins traversing the Forest of Magic Beasts. However, the journey through the forest to the Cabin takes around about 8 hours. Class 1-A arrive at the facility, battered and tired. It is now 5:20 pm in the evening. Pixiebob admits that she thought they would take longer to get to the facility; she praises Class 1-A for figuring out her Earth Beasts quickly and easily. Pixiebob then commends Izuku, Tenya, Shouto and Katsuki for taking quick action against one of her Earth Beasts and concludes that they have experienced action against villains. After Kouta punches Izuku in his crotch and harshly replies to Tenya, Katsuki comments that Kouta thinks he is an adult; Shouto replies that Kouta reminds him of someone who also acts like an adult (referring to Katsuki himself). Katsuki tells Shouto that he doesn't keep his emotions bottled up like someone he knows (referring to Shouto) while Shouto replies that he was joking.

Class 1-A fetch their luggage and put it in their rooms, Class 1-A head to the dining hall and have dinner; they enjoy the delicious food that the Pussycats provide them. After finishing dinner, Class 1-A go to the hot springs. The next day at 5:30 AM, Class 1-A are outside the training camp cabin. Shouta greets his students and tells them that they will undergo reinforcement training to strengthen and upgrade their Quirks which will also allow Class 1-A to obtain their temporary licenses.

Shouto trains along with the rest of his class. Later that day at 4:00 PM, Pixiebob and Ragdoll provide Class 1-A food materials and tell them that they must make their own food from now on. Tenya sees this as survival skill training and motivates his class to start making curry. Class 1-A begin making their own curry; Mina asks Shouto to make some fire, causing Momo to remind everyone to not rely on someone else otherwise they won’t learn how to make food on their own. Shouto decides to help Mina anyway and lights a fire for her. After finishing their cooking, Class 1-A decide to eat their curry.

On the third day, Shouto continues his training along with his class and Class 1-B. That evening, Class 1-A and 1-B are cooking themselves dinner. Shouto asks Izuku what he wanted to talk to All Might about; Izuku replies that he wanted to talk to him about Kouta. However, Izuku sees that Kouta is not around and surmises that he went back to his secret base. Izuku tells Shouto that Kouta doesn’t like the idea of a superhero society with Quirks and is unable to help him out with words. Izuku asks Shouto for advice. Shouto tells Izuku that words alone will not help Kouta since he would find reasoning from strangers to be pretentious. Shouto advises Izuku to tell him about what Heroes are doing and the help Heroes will bring to humanity. Shouto tells Izuku that he believes that action speaks louder than words. Izuku becomes encouraged from hearing Shouto’s advice and knows Shouto is correct. Class 1-A and 1-B finish dinner.

Later that night, Shouto is paired with Katsuki for the test of courage. A few minutes after entering the forest, Yui tries scaring Shouto and Katsuki, although to no avail. Suddenly, the League of Villain's Vanguard Action Squad attacks. Shouto (while carrying an injured Kousei Tsuburaba) and Katsuki run through the forest. Seeing that the situation is chaotic, Shouto decides that they should head back to the facility to regroup. While running to the facility, Shouto and Katsuki encounter a villain; Katsuki asks Shouto who is supposed to be ahead of them, to which Shouto answers Fumikage and Mezou. The villain is admiring something on the ground; a severed arm. However, the villain realizes he has work to do and cannot afford to be distracted by the severed arm; the villain turns his attention to Katsuki and Shouto.

Shouto engages in combat with the restrained villain (known as Moon Fish), using his ice to block the villain’s teeth enlarging Quirk. Moon Fish proves to be highly skilled, being able to break through Shouto’s ice and nearly hit Katsuki with one of his teeth, only to be intercepted by Shouto’s ice. Shouto warns Katsuki to not use his Explosion Quirk due to the fear of igniting the poisonous gas and causing more chaos, much to Katsuki’s annoyance. Moon Fish continues breaking through Shouto’s ice defenses with his teeth enlarging Quirk while also using his teeth to maneuver himself around. Shouto analyses that retreat is not possible since they will get caught in the gas and concludes that he and Katsuki are in a bind.

Shouto and Katsuki continue their battle with Moonfish; Shouto is unable to fight properly due to carrying Kousei. The Shouto tries his best to keep Moonfish at bay by blocking his path with ice. Katsuki becomes furious that he is unable to fight back, thinking that firing a huge explosion should stop Moonfish, but Shouto warns Katsuki that the huge explosion will limit their visibility and give the villain more attacking opportunities. When Mezou and Izuku arrive to Katsuki and Shouto's location, Mezou asks one of them to make light. Before he can explain further, Moonfish senses Mezou and Izuku’s presence and sends one of his teeth to attack them. Suddenly, the rampaging Dark Shadow appears and uses its enormous claw to crush Moonfish, destroying Moonfish’s teeth. Shouto and Katsuki are surprised at what transpired.

After the rampaging Dark Shadow effortlessly defeats Moonfish, Katsuki and Shouto manage to get close to Fumikage and use their Quirks, which calms down Dark Shadow; Dark Shadow reduces in size and retracts back into Fumikage, allowing Fumikage to return to normal. As Fumikage and Mezou reconcile, Shouto is amazed that Fumikage's Dark Shadow was wable to defeat Moonfish with ease. Izuku tells Fumikage that their top priority is to protect Katsuki, who is the target of the villains’. Izuku decides that they should escort Katsuki back to the facility and take a shortcut through the forest to do so; Izuku thinks that with the power of Mezou’s scouting capabilities, Shouto’s powerful Quirk and the unrivaled power of Fumikage’s Dark Shadow, escorting Katsuki will be a cinch. However, Katsuki is angry that he needs protecting and refuses their help. The Bakugou Escort Squad (consisting of Mezou, Shouto, Izuku and Fumikage) begin escorting a begrudging Katsuki back to the facility.

The Bakugou Escort Team travel to the facility and come across Ochako and Tsuyu. After seeing that Ochako and Tsuyu are alright, Izuku asks them to join the escort. However, Ochako and Tsuyu wonder why Katsuki isn’t with them. Mezou, Shouto and Izuku turn around only to find that Fumikage and Katsuki are missing.

Suddenly, a masked villain appears on a tree branch and reveals that he used his “magic” to take Katsuki by turning him into a marble. The masked magician-like villain, known as Compress, states that the Heroes don’t deserve someone of Katsuki’s caliber and notes that Katsuki will shine even brighter on the villains’ side. Izuku demands that he give Katsuki back.

After handing Kousei to Ochako, Shouto attempts to stop Compress by trying to freeze him with his ice attacks, but Compress's speed allows him to avoid Shouto's attacks. Compress also reveals that he captured Fumikage as well due to being impressed with his victory against the powerful Moonfish and states that he will be very useful, much to Izuku's anger. Compress begins escaping. Shouto refuses to allow them to succeed in their mission and prepares to chase after him. Before he attempts to give chase, Izuku hatches a plan to save Fumikage and Katsuki; Izuku asks Ochako to make him, Shouto and Mezou float, then tells Tsuyu to useher tongue to throw their weightless bodies as hard as she can towards the magician, which will allow the three of them to fly towards the villain with Mezou using his arms to guide their trajectory; once they are in reach of the villain Ochako will deactivate her Quirk. However, Ochako and Shouto see that Izuku’s injuries are severe and think he should stay put. Izuku insists that he goes along which convinces Ochako and Shouto. They execute the plan; Tsuyu wraps her tongue around Izuku, Mezou and Shouto while Ochako uses her Quirk to make them weightless. Tsuyu throws the weightless Izuku, Mezou and Shouto towards the Compress. The three fly at Compress at high speed and reach him. Ochako deactivates her Quirk, causing them to land on Compress and smash him onto the ground. Izuku, Mezou, Shouto and Compress landed right at the Vanguard Action Squad's rendezvous point. After apprehending Compress, Izuku, Shouto and Mezou see that they are right in front of Dabi, Himiko and Twice.

Dabi asks Mr Compress to dodge and launches his flames. Mr Compress gets away; Shouto is able to dodge Dabi’s flames, but Izuku and Mezou are not able to, causing their right and left arms respectfully to be hit by the flames. In an instant, Twice appears behind Shouto and attacks him, only for Shouto to block Twice’s attack with his ice which sends Twice reeling. Shouto continues to hold back Twice until Mezou reveals that he took the marbles from Mr Compress.

As Izuku and Shouto rush to backup Mezou, Kurogiri arrives and blocks their path. After Himiko, Twice and the Noumu escape, Mr Compress reveals that the marbles Mezou took are not the captured targets and are decoys instead; the marbles Mezou took transform into ice, which shocks Mezou. Mr Compress removes his mask and sticks out his tongue which has the actual marbles. After the magican puts on his mack and slowly enters Kurogiri's Warp Gate, Yuuga fires his Navel Laser fires his Navel Laser at Mr Compress’s face, which breaks Compress’s mask and causing Mr Compress to spit out the marbles containing Fumikage and Katsuki. Izuku, Mezou and Shouto rush to grab the marbles, although Izuku starts succumbing to his injuries which causes him to fall to the ground. Mezou and Shouto continue rushing towards the marbles; Mezou grabs the marble containing Fumikage, thus saving him. Shouto is almost in reach of the marble containing Katsuki and nearly grabs it, but Dabi snatches it away before Shouto can grab it.

Mr Compress deactivates his Quirk which frees Fumikage and Katsuki. Shouto watches as Katsuki is teleported away with Dabi and Mr Compress.

Quirk and Abilities
Half-Cold Half-Hot (半冷半燃 Hanrei Hannen): Shouto's Quirk gives the right side of his body the power of ice and his left side the power of fire. His Quirk allows him to use his fire and ice to raise and lower temperature. This Quirk gives him the ability to create ice and fire from nowhere. Shouto has shown great usage with his ice power, as he was able to create massive ice glaciers.The drawback to his Quirk arises from his need to maintain his own body temperature. Excessive use of his ice power causes Shouto to suffer from frostbite and his ice attacks as a result become weaker. However, Shouto can easily solve this drawback with his fire power, using his fire to heal himself from the frostbite.

Moves

 * Giant Ice Wall (大氷壁 Daihyōheki) Shouto creates a humongous ice glacier. This move was first used against Hanta Sero in Chapter 34 but was unnamed until Chapter 64.

Notable Combat Skills: Shouto has been stated to be the strongest student in Class 1-A. Katsuki was shown to be envious of Shouto's strength after seeing him in action in the Battle Trial. He was able to defeat all the villains in the landslide area at USJ all by himself without much trouble and was able to provide valuable assistance to All Might during his battle with Noumu. Shouto was also able to hold his own against Stain, a powerful and infamous villain, with Stain himself commenting that Shouto is powerful.

Equipment
Shouto's second hero costume was design so he can use both of his ice and fire side in combat in a more efficiently way. By canceling the negative aspects of his quirk as much as possible or better used either side of his quirk.
 * Shouto's Jacket- It contains special fiber which is capable of withstanding heat. There is a special device near the neck that senses Shouto's temperature; this automatically cools down or heats up accordingly. It is used for supporting the vest.
 * Shouto's Combat Vest- It is capable of sensing Shouto's temperature which automatically cools down or heats up accordingly. It could only heat up before.
 * Shouto's Belt- The metal capsules that hangs on the belt contains water, pain medication, and disinfectants. This makes up the first aid kit.
 * Shouto's Boots- They contain spikes that are placed under the soles. This prevents slipping in frozen places.

Endeavor
Flame Hero Endeavor is Shouto's father. Shouto's relationship with his father is on negative terms as Endeavor only sees Shouto as a tool for surpassing All Might; Shouto despises his father for seeing him as nothing more than a tool and hates him for his abuse against him and his mother.

At a very young age, Endeavor began training Shouto but the training was harsh and detestable. This was where Shouto began to dislike his father, telling his mother that he never wanted to become a Hero like him. Shouto's resentment of his father only further increased when he started to abuse his mother as well as prevent him from interacting with his brothers. After Endeavor sent his mother to the hospital, Shouto snapped and outright said to his father that he hates him, blaming him for everything that has happened.

Although Shouto hates his father for his lousy personality and what he did throughout his childhood, Shouto does not entirely despise his father as he acknowledges his father's intelligence, judgement, and insight.

Shouto's Mother
Unlike his father, Shouto's mother was kind, caring and loving towards Shouto and in return Shouto loved her deeply.

Shouto hated his father for always abusing his mother. When Endeavor began to train Shouto which was harsh and detestable when he was five, Shouto's mother intervened, trying to stop Endeavor's mad training methods but only to fail. Shouto's mother supported Shouto in these dark times, saying to him that its okay to become a hero, telling him that he is not a slave to his bloodline and that he can become whatever he wants to be.

However, Shouto's mother soon became insane from all the abuse by Endeavor and started to hate him as well as Shouto's left side. She finally snapped and threw boiling water over Shouto's face, causing a burn over his left eye. However, Shouto bore no ill will against his mother for this incident and showed no hatred for her. Instead, Shouto asked where his mother was and became shocked that she was admitted to the hospital, starting to cry and blamed his father for what happened to her.

Even after everything that happened in the past, Shouto still loves his mother. Shouto met with his mother after the Sports Festival and she reconciled with her son. Thus, Shouto's relationship with his mother has returned to what it was in the past; a loving relationship between mother and son. Thanks to reconciling with his mother, Shouto has come to terms with using his Fire power.

Izuku Midoriya
Shouto saw Izuku as his arch rival due to him having connections with All Might (a person whom his father has a rivalry with). Shouto's interactions with Izuku were of a serious nature but not to the point of antagonistic; after Stain's defeat, though, Shouto becomes friendlier with Izuku. After Izuku made him use his fire power during the Human Cavalry Battle, Shouto started to take Izuku seriously, going so far as telling Izuku his backstory and declaring to him that he would surpass him using only his ice powers and in the process disown his father. Izuku has a lot of respect for Shouto, admitting that he is far stronger than him. Although Izuku wants to defeat Shouto, Izuku started to show sympathy for Shouto after seeing his sadness and resolved to help him. During the final clash in their battle, Shouto thanked Izuku. After his fight with Izuku, Shouto has begun to acknowledge Izuku's prowess, noting that he is a person compelled to help people no matter what.

In the Field Training Arc, when Izuku sends out a message for emergency back-up, Shouto is the first and only to arrive, telling his father that his friend needed his help, making it apparent that he views Izuku as a friend now.

Katsuki Bakugou
Shouto and Katsuki have interacted a few times such as in the Obstacle Race during the Sports Festival where they had a brief scuffle for first place and before they faced each other in the final match of the Sports Festival's tournament event. Shouto appears to not be fond of Katsuki's aggressive personality and doesn't seem to see Katsuki as a rival. On the other hand, Katsuki was shown to be envious of Shouto's strength after seeing him in the Battle Trial. However, Katsuki dislikes Shouto's cold attitude. Unlike Izuku, Katsuki doesn't care about Shouto's problems or feelings. It seems that by the end of the first semester, Shouto and Katsuki appear to be neutral with each other, enough for them to have limited social interactions with each other without hostility as shown when they joked to each other about Kouta reminding them of people they knew.

Tenya Iida
Shouto appears to be on good terms with Tenya, respecting Tenya for his incredible speed after their battle in the Sports Festival; Tenya appears to also respect Shouto for having the behavior of a true Hero. They are first seen interacting each other when Shouto chose Tenya to join Shouto's team in the Cavalry Battle. After the Sports Festival, Shouto becomes increasingly worried about Tenya's mental health when he heard about Tensei Iida's injuries from Stain. Shouto understood Tenya's hatred for Stain fully well as he too knows the feeling of hating someone and thus could relate to him, deciding to help Tenya overcome his bitterness such as encouraging Tenya to become the man he wants to be.

Momo Yaoyorozu
Although their interactions have been minimal, Momo and Shouto are friendly towards each other. Shouto has many similarities to Momo; they both are students who got into Yuuei through scholarships, hail from famous Hero families and have powerful Quirks. Momo always compared herself to Shouto and concluded that he is a step ahead of her; as a result, she doesn't have confidence in herself. However, this also caused her to admire Shouto for having brimming self-confidence. Shouto has respect for Momo as he voted for her during the Class President election, being one of the only two people to vote for her; Shouto even told Momo he believed that she excelled at the role of being a leader.

Shouto chose her for the Human Cavalry Battle in the Sports Festival. During the practical end of term test, Momo is paired with Shouto. After being captured by Shouta, Shouto encouraged Momo to believe in herself. This inspired Momo and gave her the confidence needed to outwit Shouta which allowed her to free Shouto.

Stain
Shouto was disgusted with Stain's ideals of killing "fake" Pro Heroes in order to achieve justice, going so far as to tell Tenya to pay no heed to him. Stain appears to respect Shouto's strength.
