Shoto Todoroki/Synopsis

History
Enji Todoroki was always overlooked by All Might and viewed as only second best, regardless of his impressive crime solving record. Enji developed an obsession with surpassing All Might, to the point of forcing a Quirk Marriage upon Shoto's Mother in order to conceive a child with a Quirk strong enough to be capable of surpassing All Might.

When he was five years old, Shoto started to receive training from his father because of his Half-Cold Half-Hot Quirk. However, the training was too harsh and forced Shoto to cry and vomit. Shoto's mother would tried to defend him, but Enji refused to listen and would even hit her in front of Shoto.

His father also prevented Shoto from interacting with his older siblings and Shoto began to despise the training and hate his father for abusing him and his mother.

During these dark times, Shoto's mother would always be there to support him. Despite the abuse she suffered, she would still try to encourage Shoto to become a hero.There was a time when they watched a TV special on All Might, where he encouraged children to make their powers their own even if they inherited their parents' abilities. In line with All Might's advice, Shoto's mother told him that he is not a prisoner of his bloodline, and could use his powers to become what he desires.

However, Shoto's mother eventually broke down from all the domestic abuse, finding it painful to look at Shoto's left side because it reminded her of Enji. One day, as she talked with her own mother over the phone about her trauma and recognized that she no longer had the mental stability to raise her son. She was startled by Shoto's sudden appearance at the door, and after seeing Shoto's left side, she snapped and threw boiling water over the boy's face, giving him a burn over his left eye.

Some time after this incident, Shoto asked his father where his mother was, to which Enji replied that he sent her to the hospital for hurting him. Shoto blamed Enji, saying that everything that happened was his fault. At some point later in his life, Shoto would forget about his mother's supportive words.

Quirk Apprehension Test Arc
On the first day of school at U.A. High in Class 1-A, Shoto manages to score second on the Quirk Apprehension Test given to the class by their teacher, Shota Aizawa.

Battle Trial Arc
The next day of school, All Might teaches the class on Basic Hero Training. He announces that the class will take part in combat training and instructs them to suit up in their hero costumes.

Shoto is teamed up with Mezo Shoji as a team of Heroes against Mashirao Ojiro and Toru Hagakure as the team of Villains. He is informed by Mezo of the opposing team's positions and instructs Mezo to go outside of the building. Shoto 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 frozen by his doing. With both Toru and Mashirao frozen, Shoto touches the core, winning the battle for Team B.

Unforeseen Simulation Joint Arc
During their next homeroom class, Class 1-A is instructed to choose a Class President. Tenya Iida suggests they take it to a vote, and Shoto votes for himself like the majority of the class. In Hero Basic Training class, Class 1-A are assigned to Rescue Training on an off campus facility. During the bus ride there, many of the classmates discuss their Quirks while Shoto remains in the back of the bus with his eyes closed. Eijiro Kirishima comments that Shoto's Quirk is perfect for becoming a famous hero.

The class reaches the training facility, Unforeseen Simulation Joint, and are greeted by "Space Hero" Thirteen, who built the facility. It was built as a training area for aspiring heroes to practice using their Quirks to save people. However, rescue training is interrupted by the arrival of several villains. While many off his classmates are paralyzed with fear, Shoto surmises that the villains have a Quirk user among their ranks that can jam communications. He figures that the villains have a concrete objective in mind, understanding that no villain would plan this ambush without a scheme in mind.

Shoto tries to evacuate with his class, but they are separated and warped into different simulation zones of the U.SJ. Shoto ends up in the Landslide Zone and immediately freezes the villains waiting for him there. He taunts them, saying they should be ashamed for being easily bested by a child. More villains attack, but Shoto easily counters and incapacitates them as well. He warns the villains that if their bodies remain frozen, they will die. He offers to unfreeze them in exchange for information on their objectives.

One of the fearful thugs tells Shoto they are in the U.S.J. in order to kill All Might. Shoto makes his way to the central plaza to find All Might trapped by Kurogiri and Nomu. Shoto freezes half of Nomu's body to help All Might get free, and boasts that the Symbol of Peace will not die on this day. Shoto stays back the remainder of the battle, watching in awe of All Might's incredible power as he defeats Nomu.

Shoto believes All Might will handle the rest of the villains as well and decides to stay back, but Izuku Midoriya rushes to help All Might. Just as Kurogiri and Tomura Shigaraki attack, Tenya returns to the U.S.J. with Pro-Heroes as reinforcements. The villains are forced to retreat, and Shoto gathers outside the facility with his classmates. He overhears Toru talking with Mashirao about the battle in the Landslide Zone. She talks about how amazing Shoto was, but he thinks to himself about how he never even noticed she was there, and how he could have accidentally frozen her. Afterwards, Shoto and the others return to school.

Sports Festival Arc
Two days after the attack on the U.S.J., Shoto and his classmates return to school and are lectured about the importance of the upcoming U.A. Sports Festival during their homeroom class. At lunch, Shoto's interest is peaked when he overhears Ochaco Uraraka and Tenya talking about All Might taking a liking to Izuku.

As the school day ends, Class 1-A is unable to leave their class thanks to the mob of students blocking the exit. The students are from other classes, and are there to scope out their competition for the festival. Katsuki Bakugo makes them all angry with his arrogant comments, putting a target on the backs of the students in Class 1-A.

For the next two weeks, Shoto and his classmates train in order to prepare for the Sports Festival. When the day comes, Shoto and his classmates prepare in their designated waiting area by changing into their P.E. clothes. Shoto approaches Izuku and tells him that despite All Might's interest in Izuku, Shoto believes he is obviously the stronger of the two. He goes on to express his intentions to defeat Izuku in the Sports Festival.

Eijiro tries to diffuse the tension, but Shoto refuses him and reminds everyone that the festival is not a team effort. Before Shoto leaves, Izuku admits that although Shoto is stronger, he will still try his best to come out on top in the festival. Shoto stoically accepts the challenge and leaves the room with the rest of his class to enter the arena.

After Nemuri Kayama explains the rules and directs the pledge, the preliminary games begin. The first round is an obstacle race four kilometers around the area. Shoto gets a head start when he freezes the cluttered corridor, but is surprised to find that many students were able to avoid his attack. Several giant villain bots then appear to block his path.

Shoto surmises that these are the same bots that students who took the entrance exam had to face. While impressed with the obstacle, Shoto wishes the U.A. faculty could have offered him something more difficult since his father is watching. Shoto proceeds to freeze the robot while it is off its balance and run past it as it falls and blocks the way of those behind him in the race.

Keeping his early lead, Shoto easily clears the next obstacle: The Fall. It is a large canyon that must be trekked by crossing tightropes. Shoto freezes a path through the Fall, but notices Katsuki gaining on him. Shoto reaches the final leg of the race: a Mine Field meant to burden those in the lead. He has to walk through the area carefully, allowing Katsuki to catch up to him. Angered, Katsuki states that Shoto issued his declaration of war to the wrong rival and the two start to fight for first place as they run.

Moments later, Shoto watches in bewilderment as Izuku flies towards him and Katsuki after riding the momentum from an explosion he created. Izuku manages to pass them, but Shoto manages to catch up to him quickly by creating an ice path.

Shoto realizes this will help others cross the Mine Field, but he has no choice if he wants to win the race. Before he or Katsuki are able to reclaim the lead, Izuku triggers another explosion that momentarily stops them both. Although close behind, Shoto crosses the finish line second after Izuku. Even though he is unhappy about not taking first place, Shoto qualifies for the second event: The Cavalry Battle.

After Midnight explains the rules to the Cavalry Battle, Shoto forms his team with Tenya, Momo Yaoyorozu and Denki Kaminari. He explains that this is the strongest formation he could think of. After Shoto explains his strategy to his team, Tenya asks if Shoto will use ice and fire to create diversions. As he responds, Shoto looks into the stands at his father. Shoto claims he never uses his left side in battle. Shortly after the Cavalry Battle begins, Team Todoroki confronts Team Midoriya.

Rival teams rush to the scene as well, forcing Shoto to make a move. He orders Denki to electrocute the other teams while using an insulation sheet created by Momo to protect himself. Afterwards, he freezes the opposing teams and takes a few of their headbands. Shota notes that Shoto is adapting his strategy because he was surprised by how many people evaded his attack in the Obstacle Race.

Even though Shoto's team corners Team Midoriya, Izuku has them keep their distance and remain on Shoto's left side. In this position, Shoto is unable to freeze them without hitting his own teammate. With time running low, Tenya uses his Recipro Burst special move, and in an isntant Shoto takes Team Midoriya's headband.

Tenya's special move leaves their team immobilized, giving Team Midoriya the chance to try and reclaim the headband. Izuku charges at Shoto with his Quirk, and Shoto instinctively uses the fire from his left arm to try and counter. Izuku uses his Quirk to break Shoto's defense and steal a headband, albeit not the ten million point one because Shoto switched the headbands around to trick Izuku, but he is too busy berating himself for using his left side to boast.

Time continues to run down and Team Bakugo joins the fray. Both Teams Bakugo and Midoriya make one final effort at the ten million points, but time runs out. Although, Shoto does not notice that Fumikage Tokoyami steals the headband off his head. Afterwards, Shoto is angry with himself for using his left side and decides to confront Izuku at the student entrance.

At first, Shoto uses silence to intimidate Izuku and when he finally speaks, says the power that came from Izuku during the Cavalry Battle was the same as All Might's. Then, much to Izuku's shock, Shoto asks if the he is is All Might's "secret love child". Izuku tries to explain that is not the case, but Shoto figures out that their is a secret connection between the two. Continuing, Shoto say that because he is the son of #2 Hero Endeavor, he has even more reason to defeat Izuku.

Shoto explains to Izuku that Endeavor is obsessed with defeating All Might, and although he was never able to do it, he is still trying to through Shoto. Shoto reveals that he was born out of a Quirk Marriage and explains some of his past. Endeavor used his money to buy out Shoto's mother's family to implement a Quirk marriage with the intent of creating a powerful child to surpass All Might. All of Shoto's memories of his mother are of her crying, as well as when she called his left side unbearable and poured boiling water on his face.

Shoto tells Izuku all of this to explain his reason for picking a fight with him: Shoto wishes to reject his father and his fire power, and plans to win the Sports Festival using only his right side. As Shoto walks away, Izuku explains his own reasons for wanting to win and then promises to do his best to defeat Shoto.

Later on, Midnight announces the Sports Festival finals will be a one-on-one fighting tournament. Shoto notices that he could face Izuku in the second bracket, and hopes that he wins. During the recreational games, Shoto uses the opportunity to mentally prepare himself.

Following Izuku's match with Hitoshi Shinso, Shoto comments that he figured Izuku would win. On his way to the ring for his match againstHanta Sero, he encounters his father. Enji calls Shoto's behavior disgraceful and says that if he had used his fire power, he could have easily crushed the past two events. He goes on to say that Shoto needs to end his childish rebellion and see to his duty to surpass All Might. He calls Shoto his greatest masterpiece, far superior to his siblings.

Shoto only replies that surpassing All Might is all his father ever has to say, and declares that he will only use his mother's Quirk to win. His father replies that Shoto will soon discover the limits to that power. Enji's words infuriate Shoto, and he carries this anger with him into the fight.

As the match begins, Hanta nearly throws Shoto out of bounds by wrapping him in tape and swinging him towards the margin line. Shoto fiercely retaliates by freezing Hanta in a humongous pillar of ice and frees himself by breaking through the now frozen tape. Hanta is immobilized and Shoto is declared the winner. The former comments on how Shoto went overboard, and Shoto apologizes and explains that he was angry, and uses his left side to melt Hanta out of the ice.

Six matches later, Shoto watches Katsuki's battle with Ochaco closely. Once the first round of matches ends, Shoto takes to the ring and meets his second round opponent: Izuku Midoriya. As soon as their fight begins, Shoto leads with an ice attack, but Izuku counters with a Delaware Smash. Shoto creates a block of ice behind him to keep from being blown out of bounds, as he expected Izuku to injure himself in order to destroy the ice.

Shoto persistently attacks until Izuku breaks all of the fingers on his left hand. Shoto withstands the smash and creates a tower of ice to run up and close the distance between them. Izuku uses another smash to break the ice steps apart, but Shoto avoids it and nearly freezes Izuku at close range. In order to break the ice that is slowly freezing him, Izuku sacrifices his entire left arm and lets off a full powered smash. Shoto withstands the aftershock of the smash using an ice blockade. While recovering, Shoto notes that this attack from Izuku was significantly more powerful than the previous ones, and that he realizes his opponent is trying to keep him at a distance. Izuku is startled by Shoto's combat awareness, and some viewing fans even comment that Shoto is already stronger then the average Pro-Hero.

Questioning Izuku's durability, Shoto asks if he is already too worn out from defending against the ice. Izuku does not respond and instead notices that Shoto is shaking because of the frost building up on the right side of his body. Shoto apologizes for the battles intensity and thanks Izuku for helping him irritate Endeavor by using only ice rather then fire. Understanding that Izuku has no healthy fingers left, Shoto sends an ice attack at him that he expects to finish the match. Shoto is shocked when Izuku declares that he is not finished yet and uses his already broken finger to counter the ice once again.

Shoto asks why Izuku is going so far, to which he replies that Shoto is trembling, pointing out that Shoto's body can only take so much cold because Quirk's are physical abilities. He also surmises that Shoto could offset his temperature by using his fire, but knows Shoto refuses to do so. He challenges Shoto to put more effort into the battle, stating that everyone else is giving it their all while Shoto is only using half his power. Izuku provokes Shoto by claiming that he has yet to injure him in this battle, demanding that Shoto use his full strength.

Agitated, Shoto asks Izuku if Endeavor bribed him asking for the fire power. He rushes Izuku, albeit much slower than before because of the frost building up on his body. Shoto closes in on Izuku, but as soon as he lifts his right foot to attack Izuku strikes him in the torso. Shoto is partially able to freeze Izuku's other arm, but is still sent flying away. Shoto recovers and tries to use another ice attack, but it is much slower then the previous ones and Izuku is able to avoid it. They both move into closer quarters and fight in spite of their afflictions.

As Izuku dashes at Shoto, the latter attempts to freeze him. Without any fingers left to use, Izuku pulls back his thumb using his cheek in order to release another smash to blast Shoto away. Shoto asks again why Izuku is putting himself through so much pain, to which his opponent replies that he is prepared to do whatever it takes to become a hero. Izuku headbutts Shoto and challenges him to use his full strength again, telling him to stop screwing around because even if he wants to reject his father, Shoto does not have the right to be the best if he is not prepared to do his best.

Izuku's words make Shoto recall the terrible memories of his past. As more frost covers his body, Shoto remembers he and his mother being abused by Endeavor. As well as a time where he pleaded to his mother about not wanting to become like his father, to which she replied by asking if Shoto still wants to become a hero. Izuku capitalizes and strikes Shoto with another punch, and declares that he will surpass him. While reeling from the attack, Shoto is reminded of his childhood.

Still haunted, Shoto states once again that he will reject his father, but this time Izuku adds that Shoto's Quirk is his own, and not his father's. This invokes one last memory, one that Shoto had long forgotten. He and his mother were sitting down watching a special on TV about All Might, who encouraged all children to use their Quirk's in their own way in spite of inheriting them from their parents. Shoto's mother added that Shoto must remember to stay true to himself, that he is not a prisoner of his lineage, and that it was okay to use his power to become whom he wants to be.

Impassioned, Shoto ignites his flames and astounds the entire arena with his display of blazing power. When the flames die down a bit and the ice melts from Shoto's body, he says that now Izuku is the one screwing around for helping his opponent. Shoto adds that just like Izuku, he desires to become a hero one day too. Having freed Shoto from his self-repression, Izuku smiles and comments that Shoto's power is amazing, to which he responds with an affecting smile of his own.

With the battle reaching its climax, Shoto asks why Izuku is grinning in such a hopeless situation, and pleads for Izuku not to blame him for what happens next. They both build up in preparation for one final clash. Ken Ishiyama and Midnight decide to step in, fearing one of them might die. Shoto sends a large wave of ice at Izuku, and the latter evades by jumping above it. As he flies towards Shoto, he prepares a full power smash in his healthy arm, and Shoto counterattacks with a powerful fire blast. Just before he uses the fire attack, Shoto thanks Izuku.

Even though Cementoss builds a wall between them, Shoto's fire attack and Izuku's wind pressure create an explosion that destroys the entire fighting ring. The smoke clears, and Izuku is revealed to be unconscious outside the ring. Everyone is taken back by the battle's outcome, and Shoto stands victorious with half his shirt burned off.

Shoto exits the arena and encounters his father in the corridor. He praises Shoto for using his left side but tells him he needs to control it. Enji offers Shoto the chance to become his sidekick after graduation, but Shoto ignores it and reveals he has not rescinded his disavowal of his father. He reveals the only reason he used his left side is because he forgot about Endeavor during that moment completely. As he walks away, Shoto says he remains unsure about his fire power and suggests he may not need Endeavor at all.

Once the second round finishes, Shoto returns to the arena with a new uniform to face off against Tenya. He starts the match by trapping Tenya between two rows of ice. He goes in for the win using another ice attack, but Tenya evades using a standing long jump and activates his Recipro Burst technique in mid-air. Shoto is able to evade Tenya's initial roundhouse kick, but falls victim to the subsequent attack thanks to Tenya's blinding speed. Tenya tries to swiftly carry Shoto out of bounds, but is stopped asudden. He realizes that his engine's have been frozen, and questions when Shoto did so.

Shoto reveals that it was after getting hit with Tenya's second kick and suggests that Tenya had forgotten his ability to freeze with precision because he's only been showing off ranged attacks during the festival. After freezing Tenya's body completely, Shoto admits that his opponent's Recipro Burst was too fast to dodge. Midnight declares him the winner and he advances to the final round. After Katsuki advances to the finals as well, Shoto meets his menacing glare.

They meet in the waiting area when Katsuki accidentally barges into the wrong room. Before Katsuki interrupted him, Shoto was mulling over the conflicting memories of his mother's breakdown and Izuku's encouragement. Katsuki tries to intimidate Shoto by slightly blasting the table and warning him to do his best. Mostly unphased, Shoto replies that Izuku told him the same thing, and comments that he was foolish for focusing more on helping him then winning their fight. He asks Katsuki if Izuku was helpful during their childhood, but this only infuriates the former. Katsuki kicks over the table and yells for Shoto to ignore Izuku and his family issues so that he can use his fire during their bout. He angrily exits the room and states he wants to everyone to know he beat Shoto at full strength.

Their battle begins with Shoto using a more controlled version of the giant ice attack he defeated Hanta with. Katsuki endures the ice blast by tunneling through it using his explosions. Katsuki rushes Shoto and Shoto moves to counter attack, but Katsuki evades using a mid air explosion and grabs onto Shoto's left side and throws him. Shoto creates and surfs an ice wave to avoid going out of bounds. Katsuki attacks again and Shoto is able to stop him by evading his blast and grabbing onto his forearm. Rather than using the flames in his left arm (the same arm he used to grab Katsuki), he simply tosses him away.

Shoto mulls over his opponents words, internally apologizing to Katsuki because he is still too unsure about what his left side means to him to use it. Then suddenly, Shoto is once again encouraged by a shouting Izuku, who tells him not to give up and to do his best. Impassioned once again, Shoto ignites his flames and prepares to counter Katsuki's next move. Katsuki readies his special move: Howitzer Impact, but Shoto is haunted by memories of his parents and decides to extinguish the flames and leave himself completely open to Katsuki's powerful explosion. Shoto is knocked out of bounds, and Katsuki is declared the winner.

At the Sports Festival's award ceremony, Shoto is presented with the silver medal by All Might and he inquires to why Shoto refused to use his fire. Shoto replies that although Izuku opened his eyes, he still doubts himself and believes his path to becoming a hero is still clouded. He also mentions that he understands why All Might has such an interest in Izuku. After returning to class, Shoto and the rest of Class 1-A are excused from the next two days of class.

The next day Shoto decides to visit his mother in the psychiatric ward, much to his sister's disapproval. Throughout his life Shoto believed the sight of him would only cause his mother more pain, so he never visited her. Nevertheless, Shoto needs closure from his mother so that he can continue on his path to becoming a hero without anything holding him back. He musters up the courage to approach her, and resolves to talk over everything and free her from the ward's custody.

Field Training Arc
Once class resumes at U.A., Shoto joins his class in learning about Hero Informatics. Mister Aizawa reveals the Pro-Hero draft results, with Shoto leading the entire class with 4,123 offers from pros. Midnight joins the class to help the students choose their hero names. Shooto opts to choose his own first name for his code name.

After choosing code names concludes, Aizawa informs his students that they will choose a hero agency to intern at for a week from from a list of their nominations. Shoto notices that his father's work place is among his choices. When the first day of the internships arrive, Shoto meets with his class at the train station to get his new costume and travel to the office of his choice. Before he departs, Shoto notices that Tenya appears to be unsettled by news of his brothers assault at the hands of Hero Killer Stain.

Shoto reaches Endeavor's agency and gets greeted by his father. He claims Shoto has finally chosen to follow him, but Shoto refutes that, saying that he is following his own path. Endeavor immediately decides to take Shoto out into the field, and they leave for Hosu city to track down the Hero Killer.

While in Hosu City, Shoto and his father notice an explosion in the distance. Endeavor rushes towards the event, but Shoto receives a message on his cellphone from Izuku with a location on it. He tells his father to go handle the event while he heads to the location, and requests for his father to send him reinforcements.

Shoto arrives at location just in time to save Tenya from the Hero Killer: Stain. He forces Stain back using a blast of fire and then scolds Izuku for not supplying anymore details in his message since he was almost too late. Shoto tells Izuku that he figured out his message was likely a cry for help and that Pro Heroes are on the way. He uses a waves of ice to keep Stain at bay while securing his allies at the same time. Stain evades another stream of fire and Shoto declares the he won't allow the hero killer to kill anyone there.

Izuku warns Shot that Stain's Quirk can paralyze him if he gets some of his blood. Shoto plans to fight at a distance, but Stain catches him off guard and nearly takes his head off with a throwing knife. Shoto narrowly moves his head out of the way and the blade cuts his face open. Stain attacks Shoto from above, but he blocks it using a block of ice. Then Shoto notices that Stain threw his Katana at the same time as a distraction. Shoto's opponent grabs the collar of his costume and almost brings him close enough to lick the blood from his cheek, but Shoto uses his flames in time to repel him.

Stain praises Shoto for his strength and is forced back by combination attacks of both fire and ice. Tenya pleads for Shoto to stop because "Ingenium" must be the one who defeats the hero killer. Shoto replies that his statement is strange because he never saw the scowl of vengeance on Ingenium's face that he see's on Tenya and he knows there's a lot going on behind the scenes in his family as well. He creates a giant wall of ice, but Stain slashes through it and tells Shoto that it's foolish to block his own view when his opponent is father then him. Then Stain stabs Shoto's left with two throwing knives and moves above him.

Just as he's about to stab Shoto from above, Izuku unexpectedly grabs him and tackles him away. Shoto guesses that Stain's Quirk may have a time limit, but Native explains that Izuku was the last to suffer from it, so that cannot be the case. Izuku comes to the conclusion that Stain's power's effectiveness varies depending on blood type, to which the hero killer confirms.

Shoto states that he would have liked to carry the injured away but Stain won't give him the opening to do so. He and Izuku decide to hold the villain off until reinforcements arrive. With Shoto already bleeding, Izuku volunteers himself to fight in close quarters while Shoto supports him from a distance. Although reluctant to the risk, Shoto agrees to protect Tenya and Native together with Izuku. He recalls worrying about Tenya ever since Ingenium was attacked because he recognizes someone who's acting on pent up resentment. Shoto also knows too well how that negativity can cloud someone's judgment.

He remembers visiting his mother and how it cleared up his own perception. He told her everything that happened and so she apologized for burning him and forgave Shoto for not visiting her for a long time. She also encourages him to move forward in his life without anything holding him back, as that would be her salvation. That's why he decided to intern with Endeavor's agency, not because he has forgiven his father, but because he wishes to learn from the experience of the number two hero. Shoto realizes now that everything could have been simpler for him, but never noticed until Izuku opened his eyes with just a few words.

With the battles intensity increasing, Stain heightens his strength and overpowers Izuku. He cuts open his leg and licks the blood to paralyze him. Shoto tries to support him, but Tenya again pleads for them to stop. Shoto rejects his plea and tells Tenya to stand up if he wants them to stop. Stain dashes towards Shoto, evading the ice the latter sends at him. Stain slashes through a wall of ice and goes to attack Shoto, who responds by releasing his fire and encourages Tenya to never forget who he wants to become.

As Shoto tries to force Stain back, the villain inches closer to him everytime he evades a stream of flames. Shoto uses his ice as well, but Stain is too fast and closes the distance between them. The Hero Killer comments that Shoto is careless because he's too focused on his Quirk and nearly takes him out using the katana. Tenya breaks free from the paralysis in time to save Shoto using his Recipro Burst to break the katana and kick Stain flying back.

Tenya apologizes for getting his friends involved, but Stain refutes this and states that Tenya will never reform into a true hero. Shoto tells Tenya not to listen to the villain's words, but Tenya agrees that he isn't a true hero. Nevertheless, Tenya believes he can't give up or else the name of ingenium will die. Stain attacks again, but Shoto forces him back using his fire. Native urges Shoto to flee, but he refuses and says that Stain won't give him an opening. Although Shoto realizes that Stain's Quirk isn't especially effective in a battle against multiple opponents, he notes that Stain has only gotten more tenacious in his attempts to kill his targets.

While Shoto keeps Stain at bay using ranged fire attacks, Tenya asks him if he can regulate temperature. Shoto responds by admitting he's not used to doing so with his left side yet, but Tenya asks him to freeze his legs without blocking the exhausts. Annoyed with Shoto's interference, Stain maneuvers behind him and throws a knife at his head. Tenya moves in front of the blade and it stabs him in the arm and gets pinned down by a second knife. This gives Shoto enough time to do as Tenya asks and cools down the radiators on his leg. This allows Tenya to unveil his new special move: Recipro Extend. Then Tenya and Izuku rush Stain by using their Quirk's to scale the alleyway and strike the Hero Killer simultaneously.

Stain reels back from the student's teamwork and tries to slash Tenya, but he evades and kicks the villain higher into the air. Realizing that this is his chance, Shoto blasts Stain and finally connects with a stream of fire. He secures his allies by using ice to lighten their falls and tells them to get ready to continue fighting. However, Shoto looks up and sees they have actually defeated their opponent.

Shoto restrains the defeated Hero Killer using rope and follows Tenya, and Native carrying Izuku out to the street. He comments that they barely won three on one with Stain making several mistakes and that it's likely Stain became flustered and forgot Izuku's recovery time, making him unable to compensate for their last joint assault. They are met by several Pro-Heroes who offer to call an ambulance and the police. Tenya cries and takes a moment to ask for his friends forgiveness and Shoto says that Tenya is the class president and needs to pull himself together.

Then suddenly the last Nomu swoops down from the sky and snares Izuku. Before it gets to far away, Stain recovers and uses his Quirk to stop it. Then he saves Izuku by grabbing him and stabbing Nomu's brain. In spite of being heavily injured, Stain states that the "fake" pro heroes and the pathetic criminals in society must be purged to create a more just society. Shoto and everyone are taken back by his actions. Endeavor and Stain challenges all the heroes to try and stop him. The bandages over his face fall off and Stain releases a malicious aura that paralyzes everyone with fear, including Shoto. The Hero Killer prepares to attack, but his perforated lungs cause him to lose consciousness.

The next day, after being taken to the Hosu General Hospital, Shoto, Izuku and Tenya discuss their previous battle with the Hero Killer. The Chief of Hosu Police, Tsuragamae Kenji, arrives, and tells the three that the Hero Killer is undergoing treatment. Tsurugamae states that the trio acted on their own without the supervision of their superiors and as such violated the rules, thus they, along with their superiors, will be punished.

Shoto becomes enraged over the fact that Tsuragamae expected them to follow the rules and let people die as a result, saying that the job of a Hero is saving people. Izuku, Gran Torino and Tenya stop Shoto. However, Tsuragamae states that there were limited witnesses and as a result there will not be any punishment for the trio, but they won't be receiving any praise from the public, as the events that occurred the previous day will be covered up. The three thank the Chief of Police for not punishing them. Tsuragamae thanks them for their heroic actions.

The following day, Izuku and Tenya discuss their hand injuries and promise each other to become stronger. Shoto apologizes, confusing Izuku. Shoto says that he seems to be cursed—whenever he is involved, people's hands go bad. Izuku and Tenya are surprised that Shoto can crack a joke, but he claims to be completely serious, calling himself a "hand crusher", causing the young Heroes to laugh.

The workplace training comes to an end and Shoto returns to U.A.. During Foundational Hero Studies, Shoto watches the first group race through the construction site. Seeing Izuku's speedy movements, he notices that they remind him of someone.

End of Term Test Arc
As Denki despairs over the upcoming end of term test, Shoto remarks that if he had just attended classes normally then he would not have such low grades. In the lunchroom, Izuku, Tenya, Shoto, Ochaco, Tsuyu and Toru 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 Shoto as well before storming off. On the day of the exercise test, the Principal reveals that Class 1-A will be fighting against U.A.'s teachers in their exercise test. Shoto is paired with Momo and they must face Shouta Aizawa in their exercise test.

Shoto, Momo and Aizawa arrive in a replica city where their test exercise will take place. After the rules are explained, the test begins. Shoto asks Momo to create random objects in order detect when Aizawa has seen them, deducing the test will depend on who finds who first. Shoto says he will fight Aizawa while Momo makes an escape, and instructs Momo not to get separated from him until then.

Shoto is confused over what are the objects Momo is creating, and she explains to him they are Russian dolls. Momo says she's impressed with Shoto for being able to think of a strategy and have the judgement to make quick decisions. Shoto tells Momo that it's nothing special, but Momo sadly says that even though she is a recommended freshmen like him, she has yet to show any noteworthy results.

Suddenly, Shoto realizes that Aizawa is nearby, causing Momo to apologize for being distracted. The teacher appears from above, hanging from telephone wires. He comes down and Shoto attempts to attack him, but misses. Shoto tells Momo to run away. Aizawa then wraps his bandages around Shoto and hangs him from the telephone wires, tying them to a telephone pole. Shoto points out that he can break free from his bonds by using fire or ice, but Aizawa throws caltrops underneath him to stop Shoto from doing so. Before leaving, Aizawa commends Shoto for thinking of Momo, but points out that he should have instead listened to what she had to say.

As Aizawa pursues Momo, Shoto is still hanging from the telephone wires, thinking about what the teacher had said. Suddenly, Momo appears and apologizes to Shoto, being unable to decide what to do: rescue him or escape. Shoto apologizes to Momo for not taking her ideas into consideration and asks if she has something in mind. Momo says she does, but doesn't think it would work if Shoto's plan fell flat.

Shoto encourages Momo to put her plan into action, telling her that he voted for her during the Class President election because he feels she is fit for the role. Aizawa then appears above Momo, preparing to attack. Feeling more confident because of Shoto's words, Momo tells Shoto to close his eyes and throws the Russian dolls she created into the air. They open up to reveal flash grenades in them, preventing Aizawa from advancing and using his Quirk. Momo frees Shoto from the telephone wires, then confidently declares to him that she does have a plan to prevail over their opponent.

Aizawa launches his capturing weapon against Shoto and Momo, but they avoid the attack and Shoto counters by trying to use fire; however, Aizawa erases Shoto's Quirk. Momo and Shoto run to escape from Shouta's line of sight. Momo instructs Shoto to use his Quirk when Aizawa blinks. As soon as he has the opportunity, Shoto creates a humongous ice pillar that completely eclipses Aizawa's view. Unable to see anything, the teacher stands by.

Momo creates a replica of Aizawa's weapon and explains her plan to Shoto. The two then move away from the ice wall, while covered by black cloaks. Aizawa attacks the concealed duo with his capturing weapon, but only captures a mannequin Momo was holding. Momo fires the replica weapon from a catapult, and then tells Shoto to shoot heat along the ground. Shoto's fire causes Momo's weapon, made of allow with shape memory, to wrap itself around Aizawa, binding him. Afterwards, Momo and Shoto handcuff Shouta, which allows them to pass the practical test.

Shoto thanks Momo for making the plan prevail. Happy with the result, Momo is about to cry tears of joy. Shoto asks what is wrong and advises Momo that there is a pressure point on top of her foot to ease any pain, but Momo tells Shoto that nothing is wrong, rubbing her eyes.

In class, Shoto learns that he has passed both the written and practical end of term tests, and will go to the forest lodge along with the rest of his classmates. He refuses the invite to go shopping with the rest of the class, saying that he visits someone on his days off.

School Trip Arc
The day after the shopping trip at U.A., Aizawa informs Shoto and the rest of Class 1-A that the destination for their lodge trip has been changed. On the day of the event, Class 1-A boards a bus that will take them to the forest lodge destination. An hour later, the bus stops for a restroom break.

Suddenly, two females wearing cat-like costumes and a small boy appear; the females introduce themselves as the professional Hero Team, The Pussycats. The black haired female, Mandalay, explains to Class 1-A that they will be staying at the base of a mountain and that they have three hours to reach the location. The blonde female, Pixiebob, uses her Quirk to create a landslide that causes Class 1-A to fall into the forest below. Suddenly, they are confronted by an earth beast. Shoto, along with Katsuki, Tenya and Izuku use their Quirks to destroy it.

Class 1-A arrive at the facility only 8 hours later, battered and tired. Pixiebob commends Shoto, Izuku, Tenya, and Katsuki for taking quick action against one of her Earth Beasts. After Katsuki comments that Kouta thinks he is an adult, Shoto says that Kouta reminds him of someone who also thinks he's an adult.

After fetch their luggage and put it in their rooms, Class 1-A has dinner and then head to the hot springs. The next day at 5:30 AM, Aizawa 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.

Shoto trains along with the rest of his class. Later that day, Pixiebob and Ragdoll provide Class 1-A the materials to make their own food from now on. As they cook, Mina asks Shoto 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. Shoto says it's fine and lights a fire for Mina anyway.

On the third day, Shoto continues his training along with his class and Class 1-B. That evening, while cooking dinner, Shoto asks Izuku what he wanted to talk to All Might about. Izuku replies that he wanted to talk to him about Kouta, because he is unable to help the boy, who dislikes the superhero society, with words. Shoto tells him that words alone will not help Kouta since he would find reasoning from strangers to be pretentious, and that he believes that action speaks louder than words.

Later that night, Shoto is paired with Katsuki for the test of courage. A few minutes after entering the forest, Yui scares Shoto and Katsuki, making the two freeze with fear. Soon after, the League of Villain's Vanguard Action Squad attacks the camp. Shoto, carrying an injured Kousei Tsuburaba, runs through the forest with Katsuki. While going back to the facility, Shoto and Katsuki encounter Moonfish admiring a severed arm on the ground. The villain turns his attention to Katsuki and Shoto.

Shoto engages in combat with the villain, Moonfish, using his ice to block the villain’s teeth enlarging Quirk. Moonfish breaks through Shoto’s ice and nearly hits Katsuki with one of his teeth, only to be intercepted again Shoto’s ice. Shoto 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 Shoto’s ice defenses with Quirk while also using his teeth to maneuver himself around. Shoto analyses that retreat is not possible since they will get caught in the gas and concludes that he and Katsuki are in a bind.

Shoto is unable to fight properly while carrying Kousei. He tries his best to keep Moonfish at bay by blocking his path with ice. Katsuki becomes furious that he is unable to fight back, wanting to fire a huge explosion to stop the villain, but Shoto advises him against it. Suddenly, Mezo and Izuku arrive running at Katsuki and Shoto's location. Mezo asks one of them to make light. Before he can explain further, Moonfish senses Mezo and Izuku’s presence and sends one of his teeth to attack them. However, the rampaging Dark Shadow appears and uses its enormous claw to crush Moonfish, destroying his teeth. Shoto and Katsuki watch in shock.

Katsuki and Shoto manage to get close to Fumikage and use their Quirks, which calms down Dark Shadow; making it reduce in size and retract back into Fumikage. As Fumikage and Mezo reconcile, Shoto expresses his surprise over Fumikage's Dark Shadow being to defeat Moonfish in a single hit. The group decides that they should escort Katsuki back to the facility, and take a shortcut through the forest to do so. The Bakugo Escort Squad (consisting of Mezo, Shoto, Izuku and Fumikage) begins escorting a begrudging Katsuki back to the facility.

The group comes across Ochaco and Tsuyu. The girls wonder why Katsuki isn’t with them. Mezo, Shoto and Izuku then realize 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 villain, known as Mr. Compress, says that Katsuki will shine brighter on the villains’ side.

After handing Kousei to Ochaco, Shoto attempts to freeze Compress, but he avoids Shoto's attacks and begins to flee. Before Shoto attempts to give chase, Izuku comes up with a strategy to save Fumikage and Katsuki. They execute the plan: Tsuyu wraps her tongue around Izuku, Mezo and Shoto while Ochaco uses her Quirk to make them weightless. Tsuyu throws the weightless trio towards Compress. They land on the villain and smash him onto the ground. Izuku, Shoto and Mezo then see that they are right in front of Dabi, Himiko and Twice.

Dabi launches his flames towards the boys. Compress gets away, Shoto manages to dodge Dabi’s flames, but Izuku and Mezo don't. In an instant, Twice appears behind Shoto and attacks him, but Shoto blocks the attack with his ice. Shoto continues to hold back Twice until Mezo reveals that he took the marbles from Compress.

As Izuku and Shoto rush to backup Mezo, Kurogiri arrives and blocks their path. After Himiko, Twice and the Noumu escape, Compress reveals that the marbles Mezo took are not the captured targets, but decoys. The marbles Mezo took transform into ice. Compress removes his mask and sticks out his tongue, revealing the real marbles. From behind a bush, Yuga fires his Navel Laser at Compress’s face, making him spit out the marbles. Izuku, Mezo and Shoto rush to grab them. Mezo grabs the marble containing Fumikage. Shoto is almost in reach of the marble containing Katsuki, but Dabi snatches it away before Shoto can grab it. Compress deactivates his Quirk, freeing Fumikage and Katsuki. Shoto watches as Katsuki is teleported away with the villains.

Hideout Raid Arc
Two days after the incident, Shoto and the rest of his classmates visit Izuku in the hospital. Shoto and Eijiro state their plan to rescue Katsuki after overhearing Momo talking about a device that can locate a transmitter she placed on one of the villains. However, most of Class 1-A are against the idea. Shoto leaves after the doctor needs to checkup on Izuku.

Later that night, Shoto along Eijiro wait for Izuku and Momo. They arrive, but before Momo can speak, Tenya appears, angry that they are about to repeat the same mistake he made at Hosu. Shoto tells Tenya that they will not engage the villains in combat, and Eijiro explains that they're planning a covert mission. Momo states that she came along to accompany them all in order to prevent them from engaging in combat. Tenya decides to go with them.

Shoto along with Izuku, Momo, Tenya and Eijiro board a train to travel to a place called Kamino Ward, located in Yokohama City in the Kanagawa Prefecture. At the location, the group puts on disguises to prevent the League of Villains from recognizing them. They exit the clothing shop and witness a video clip of U.A.'s public apology.

Shoto along with Eijiro, Izuku, Momo and Tenya continue towards the place that Momo's tracking device is detecting. After waiting for a while near the place, Momo, Tenya, Shoto, Eijiro and Izuku prepare to infiltrate the supposed League of Villains’ hideout.

Shoto along with the group go to the back of the hideout and see a window. Shoto and Tenya have Izuku and Eijiro stand on their shoulders to see what is inside using the night-vision goggles Eijiro brought along. Suddenly, Mount Lady destroys the front of the warehouse which shocks Shoto.

Seeing that the Pro Heroes are at the warehouse, Shoto and the group assume that All Might is with Katsuki as they are speaking. Shoto and the group decide to head home. Suddenly, the entire warehouse is completely destroyed by a mysterious man along with the surrounding area being significantly damaged. The man's aura above them utterly terrifies Izuku, Eijiro and Shoto.

As the battle between All Might, Sensei, Katsuki and the League of Villains continue, Izuku knows that they are in a crisis and there aren’t any openings to rescue Katsuki due to Sensei’s presence and Katsuki being outnumbered by the Vanguard Action Squad. Suddenly, Izuku comes up with an idea and explains the plan to Shoto and the rest of the group.

Izuku puts his plan into action; Izuku and Tenya hold onto Eijiro with Izuku using One For All Full Cowl and Tenya using his Recipro Burst to burst through the wall while Eijiro uses his Hardening to protect himself, Izuku and Tenya. After Izuku, Tenya and Eijiro burst through the wall, Shoto creates an ice ramp; Izuku Tenya and Eijiro jump off Shoto’s ice ramp and head into the sky. Sensei sees the trio and attempts to attack them, but All Might intervenes by punching Sensei. Katsuki sees the trio while Eijiro yells at Katsuki to take his hand. Tomura tries to take Katsuki, but Katsuki uses his Explosion to launch himself towards Izuku, Tenya and Eijiro. Katsuki grabs Eijiro’s hand and smiles.

Seeing that Izuku, Eijiro and Tenya have succeeded in rescuing Katsuki, Shoto and Momo begin escaping from the battlefield.

Shoto and Momo successfully escape. Shoto phones Izuku and finds out that him and his group are at the train station.

Shoto and Momo meet up with Izuku's group. They take Katsuki to a Police Station for his safety. Afterwards, Shoto parts ways and goes home. Shoto arrives at the Todoroki Abode where his sister greets him and states that their father is in the training hall. Shoto walks by the training room and assumes that his father will take the position of Number One Hero now that All Might can no longer fight. Shoto sees the training hall, only to find that the room is nearly in shambles due to Endeavor’s rage; Endeavor refuses to accept the position of Number One Hero.
