Shoto Todoroki/Synopsis

History
Shoto's father, Endeavor, was always overlooked by All Might and seen as the Number 2 hero of all time, regardless of his impressive crime solving records. Due to that, Endeavor 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. However, the training was harsh and cruel to the point of making Shoto throw up. Shoto's mother tried to defend him, but Endeavor refused to listen and would even hit her. His father also prevented Shoto from interacting with his older siblings. Shoto began to despise the training and hate his father for abusing his mother. During these dark times, Shoto's mother would always be there to support him. Despite the abuse she suffered, she'd tell Shoto that he is not a slave to his blood and can become whatever he wants to be.

However, Shoto's mother started to lose her sanity due to all the abuse received from her husband, finding it painful to look at Shoto because his left side reminded her of Endeavor. 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. Seeing Shoto's left side, she snapped, and threw boiling water over the boy's face, causing a burn over his left eye.

Some time after this incident, Shoto asked his father where his mother was, and Endeavor replied that he sent her to the hospital for hurting him, much to Shoto's shock. Shoto blamed Endeavor, 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
Shoto Todoroki first appears on the first day of school at U.A. in Class 1-A. He 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 as a team of Heroes against Mashirao and Toru 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 wins 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 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 close. Eijiro Kirishima comments that Shoto's Quirk perfect for becoming a famous hero.

The Class reaches the training facility, greeted by the Rescue Hero: Thirteen. She explains that she built the facility, named the Unforeseen Simulation Joint. 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. Shoto 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 villains: Kurogiri and Nomu. Shoto freezes half Nomu's body to help All Might get free, and boasts that the Symbol of Peace won't 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 rushes to help All Might. Just as Kurogiri and Tomura attack him, Tenya Iida 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 Hagakure talking with Mashirao Ojiro 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 accidently 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 Iida talking about All Might taking a liking to Izuku Midoriya.

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 their to scope out their competion for the festival. Katsuki 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 until the day arrives. 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 isn't 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 stoicly accepts the challenge and leaves the room with the rest of his class to enter the arena.

After Chief Referee of the games: Midnight 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 out to a head start when he freezes the cluttered corridor, but is surprised to find that many students were able to avoid his attack. Shoto gets out to an early lead, but several giant villain bots appear to block his path.

Shoto is 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 "dear old man" is watching. Shoto proceeds to freeze the robot while it's off it's balance and run past it as it falls and blocks the way of those behind him in the race.

Out to an early lead, Shoto easily clears the next obstacle: The Fall. It is a large canyon that must be trecked by crossing tightropes. Shoto freezes a path through the Fall, but notices Katsuki Bakugo gaining on him. Shoto reaches the final leg of the race: a Mine Field meant to burden those in the lead. Shoto 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 quickly catch up to him 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's 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 Iida, 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 Endeavour. Shoto claims he never uses his left side in battle. Shortly after the Cavalry Battle begins, Team Todoroki confronts Izuku's team.

Rival teams rush to the scene as well, forcing Shoto to make a move. He orders Denki to electricute the other teams while using an insolation sheet prepared by Momo to protect himself. Afterwards, he freezes the opposing teams and takes a few of their headbands. Aizawa 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. However, Izuku uses his Quirk to break Shoto's defense and steal headband, albeit not the ten million point one. 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 Katsuki's team and Team Midoriya make one final effort at the ten million points, but time runs out. Although, Shoto doesn't 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 Shoto finally speaks, he says the power that came from Izuku during the Cavalry Battle was the same as All Might. Then, much to Izuku's shock, Shoto asks if the he's is All Might's "secret love child". Izuku tries to explain that isn't 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 number two 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 left 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. 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 against Hanta Sero, he ecounters his father. Endeavour calls  Shoto's behavior is disgraceful and 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. Endeavours 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.

Shortly after Eijiro and Tetsutetsu's arm wrestling game, Shoto walks into the ring to meet his second round opponent, Izuku. Once the match begins, Shoto 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 Shoto back. Shoto is hit again by the wind pressure of Izuku's attack, but uses the ice behind him to prevent himself from being blown out of the ring. Shoto sends another wave of ice against Izuku and starts charging towards him. Izuku destroys the ice again but Shoto continues to close on Izuku. Shoto 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, Shoto takes the chance to attack him.

However, Izuku strikes back by sending a huge blast of wind pressure against Shoto, which strongly knocks him back, but Shoto once again creates ice behind him to prevent himself from being blown out of the ring. Shoto 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'. Shoto 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 another blast of wind pressure, destroying the incoming ice and knocking back a surprised Shoto. Izuku states that he realized Shoto has a limit to how cold he can get from generating ice, but he could use his left side to solve that problem. Izuku criticizes Shoto for declaring that he would win using only half of his power, but has yet to land a single hit on him. Izuku then demands that Shoto fights him seriously. Shoto, now angry, asks what Izuku he is planning.

Enraged, Shoto charges towards Izuku, but the frostbite prevents him from evading properly. Izuku punches him in the stomach, knocking him down. Shoto gets back up and launches a wave of ice at Izuku, which he destroys with a blast of wind pressure and once again knocks Shoto back. Izuku says that while he may never understand Shoto's circumstances and resolution, he thinks that becoming Number One without using his full strength in order to disown someone is a joke.

Telling Izuku to shut up, Shoto starts remembering his painful past and how his father was abusive towards him and his mother. Meanwhile, he also begins to experience the full effect of his frostbite, causing frost to appear over his right side. Unable to move properly, he is hit by Izuku again. Shoto remembers the incident of his mother throwing boiling water over his face. As Shoto gets up, Izuku tells him that his power belongs only to him.

After Izuku says these words, Shoto 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 and Izuku's words, Shoto activates his fire power, setting the left side of his body ablaze. He tells Izuku that he wants to become a hero as well, and smiles.

Shoto powers up for one final attack and sends a great wave of ice towards Izuku. After thanking Izuku, he ignites the cold air generated by his wave of ice with his fire to create a huge wind blast. That, 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, Shoto is seen standing in the ring without any injuries, while Izuku is out of bounds. Shoto is declared the winner and advances to the third round.

After leaving the ring, Shoto encounters his father in the corridor. Endeavor tells Shoto that he is proud of him for accepting to use his fire power and that he has become the perfect upgrade of him. However, Shoto tells Endeavor that he cannot change so easily and hasn't rescinded his disavowal of him. Shoto then says the only reason he used his fire power was because for a split second he completely forgot about him. As he walks away, Shoto says that he still needs to think.

Shoto faces his opponent, Tenya, in his third round match. Once the match begins, Shoto attacks first with a wave of ice but Tenya dodges the ice by jumping over it.

Tenya uses Recipro Burst and tries to attack Shoto with a speed-enhanced kick, but Shoto dodges. Tenya quickly counters and attacks Shoto with another kick, slamming Shoto down onto the ground. Shoto retaliates by grabbing Tenya's leg, but Tenya kicks him away. Tenya then grabs Shoto and proceeds to try and throw him out of bounds.

However, along the way, Tenya realizes that there is ice in his mufflers, slowing him down. Shoto reveals that he put ice in his mufflers when he grabbed his leg and freezes Tenya's entire body. Unable to move, Tenya is declared defeated and Shoto advances to the final round of the tournament. While walking away, Shoto admits to Tenya that he could not fully evade his Recipro Burst and that he expected no less from it.

Shoto waits in the waiting room for his final match to begin while thinking about Izuku's words to him during their match. The door slams open, revealing Katsuki, who barged into the wrong room. Shoto doesn't pay attention to Katsuki, much to his annoyance. Katsuki complains about Shoto's attitude towards a fellow finalist and uses a small explosion on the table to get his attention.

Shoto asks Katsuki if Izuku has been the type of person who drags out peoples' problems and helps them since childhood. Katsuki angrily kicks the table over, telling Shoto that he doesn't care about Izuku nor Shoto's feelings. Before leaving, Katsuki tells Shoto to give everything he's got during their match.

Shoto goes to the arena and faces his opponent, Katsuki, in the final match. Shoto attacks Katsuki with a slightly smaller version of Giant Ice Wall. However, Katsuki thaws himself out with an explosion. He then somersaults himself into the air and grabs Shoto's hair and shirt, throwing him onto the ground. However, Shoto creates an ice wall behind himself to prevent himself from being thrown out of the ring.

Shoto is attacked by Katsuki again, but dodges his explosion and grabs Katsuki's arm. Shoto throws Katsuki into the ice wall, who becomes angry at Shoto for not using his full power. As Katsuki prepares his next attack, Shoto mentally apologizes to him and admits to himself that since fighting Izuku he is struggling on what to do.

From the stands, Izuku yells at Shoto to not give up, which makes him activate his fire power. However, as soon as he does, Shoto remembers his mother and becomes disheartened. He is then hit by Katsuki's Howitzer Impact. After the smoke clears, Shoto is out of bounds and knocked out. A furious Katsuki walks to Shoto and grabs him by his shirt, but is knocked out by Midnight's Quirk before he can do anything. Having gone out of bounds, Shoto loses.

Later, at the closing ceremony of the Sports Festival, All Might gives Shoto his second place medal and asks him about his reasons for not using his left side. Shoto explains that he still has things he needs to deal with. All Might gives him a congratulatory hug and says that he won't pry any further, and that he knows now that Shoto can come to terms with anything that is troubling him.

After the closing ceremony is finished, Shoto along with his class are given two off days. The next day, Shoto decides to go see his mother in the hospital. His older sister, Fuyumi, is surprised that Shoto is going to see their mother after such a long time and asks Shoto why, but he does not respond.

At the hospital, Shoto arrives at the door to his mother's room. Shoto 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. He takes a deep breath and enters his mother's room. Shoto's mother apologizes to Shoto and forgives him, smiling at her son through tears.

Field Training Arc
In class, after the two-day break, Shoto listens as Shouta reveals the Pro Hero nominations. Having received 4,123 Pro Hero nominations, Shoto has the highest amount of nominations out of Class 1-A. Afterwards, Class 1-A has to decide on Hero names. Shoto, however, picks his own first name as his hero name.

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

Later, Shoto is in Hosu with his father, having chosen his office as his training workplace. He receives a text message on his cellphone from Izuku, and heads to the location sent in the message. As he arrives at the alley where Izuku is, Shoto launches a column of fire and ice at Stain, forcing the villain to dodge. Shoto reveals himself, telling Izuku that he should have texted him more information and that he was almost too late.

Shoto attacks Stain with ice but he dodges, followed by a stream of fire that Stain also dodges. Shoto's attacks of ice and fire manage to bring Izuku and the injured Pro Hero to him. He then states that he won't let the villain kill them. Stain throws his dagger at Shoto's face and manages to land a cut on his face, and then appears before Shoto and attacks him with his dagger, but Shoto blocks the attack with a pillar of ice.

Looking up, he is distracted by Stain's katana, which is about to fall on him. Stain grabs Shoto and prepares to lick the blood off his face, but Shoto uses fire to knock him back. He attacks Stain with ice again, but the Hero Killer dodges and attempts to slash Shoto with his katana and dagger, but Shoto is able to defend himself with a small wall of ice.

Tenya begs Shoto to stop fighting as this is supposed to be his fight, causing Shoto to criticize Tenya, saying that the Ingenium he knows would not make a face like his. Shoto attacks the villain with great pillars of ice, attempting to block Stain's view. However, Stain cuts through Shoto's ice pillars with ease and throws two small daggers into Shoto's left arm. He then jumps into the air and prepares to stab Shoto with his katana.

Suddenly, Izuku appears before him, the effect of the Hero Killer's Quirk having wore off, 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 from Shoto and Izuku. Shoto tells Izuku that avoiding close quarters combat and holding out is their best course of action against Stain, to which Izuu agrees, telling Shoto that he will draw Stain's attention while he acts as support. Shoto states that they will protect Tenya and the Pro Hero.

Izuku tries to attack the Hero Killer, but Stain slashes at Izuku with his katana and then licks the blood on it, activating his Quirk, which paralyzes Izuku. Stain then sets his sight on Shoto, cutting through his wall of ice, removing Shoto's defense and preparing to attack him. As Tenya protests, Shoto encourages to be the man he set out to be.

Shoto attacks Stain with a stream of ice and fire, but Stain dodges. As Stain is about to cut through Shoto with his katana, Tenya uses Recipro Burst and breaks the weapon in half with a kick. Stain tells Tenya that he is a fake Hero, and Shoto says that he should to pay no heed to Stain. Shoto attacks Stain with a stream of fire and keeps him at bay, concluding that he is not as powerful as one might think and that fighting against groups is his biggest disadvantage. Stain attacks Shoto with daggers, but Tenya intercepts his efforts. Shoto then cools down Tenya's leg enough for him to regain mobility. Shoto encourages Izuku and Tenya to press on with their attacks and the duo hits Stain with a punch and kick, respectively.

Stain makes one last attempt at killing Tenya, but he retaliates with a kick and Shoto shoots a stream of fire at Stain's face. Stain finally loses consciousness and is defeated. Tenya and Izuku land safely onto the ground thanks to Shoto's ice ramp. Shoto decides to tie up Stain with Izuku suggesting that they remove Stain's weapons.

Izuku, Shoto, Tenya and Native leave the alley with the unconscious restrained Stain in tow. Tenya offers to pull Stain, but Shoto refuses due to his arm being in bad shape. After Tenya apologizes for his actions, Shoto tells him to pull himself together because he is the Class President. Moments later, Shoto watches as the winged Noumu grabs Izuku and Stain wakes up and defeats it.

Stain's mask falls off and reveals his true face, shocking Shoto. Stain walks forward and declares that the only one who is allowed to kill him is All Might, unleashing a malefic aura in the process. Shoto falls down onto the ground out of fear. After Stain loses consciousness, Shoto is shocked and speechless that he is still standing despite being unconscious.

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 a villain 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.
