Enji Todoroki/Synopsis

History
Enji desired to be the top hero and dedicated most of his life to it. However, All Might was always the most popular hero and eventually Enji realized the gap was way too big and began to hold a sense of fear and begrudging respect towards the latter. Out of spite and envy for All Might's Hero ranking, Enji bought out Rei's family in order to get his hands on her Quirk. Forcing her into a Quirk Marriage, Enji attempted to conceive and raise a child with a combination of their Quirks that would be strong enough to usurp All Might. After having several other children, Enji eventually found his "masterpiece" in Shoto.

When Shoto was five years old, Enji began training him to become a Hero. However, the training was harsh and detestable. Enji's wife tried to defend Shoto, saying that he is too young but Enji refused to listen and ordered her to stay out of his way. Enji also prevented Shoto from interacting with his older brothers and sister. After his wife threw boiling water over Shoto, Enji had her admitted to a mental hospital.

Years later Endeavor attended a meeting with other Pro Heroes and the Police Force to speak about the unwilling civilians injected with Trigger. The officer explained that the people in question were more of victims than villains. Endeavor argued that any public use of a quirk is illegal and that they should treat them as villains and let the police investigate the backgrounds of future captures. He said this is the only way to protect the innocent while not risking themselves through hesitating every time they see a new enemy. All Might, who was not present, had his reply to the problem delivered by Naomasa Tsukauchi. He stated that he would assess the situation at the scene more carefully because as heroes they must not bring harm to innocent citizens. This was in direct opposition to Endeavor's answer, greatly angering him. After the meeting ended, Suicide Bomb attacked the police station. Endeavor, still fuming over what had just transpired, decided he was going to incinerate the villain. However, the villain's quirk would have had a volatile react to Endeavor's quick. The incident was then taken care of by Eraserhead and Midnight.

Entrance Exam Arc
Endeavor's photo is posted a billboard screen when Pro Heroes unite to fight a giant enemy. He is later seen in a television ad for U.A. High School. He is first mentioned in a list of notable U.A. alumni.

U.A. Sports Festival Arc
Endeavor comes up in a conversation between fans about how his son is participating in the U.A. Sports Festival. Shoto mentions Endeavor as his "old man" when he wishes to display his ice power on stronger foes than the giant robot villains. When the Cavalry Battle begins, Endeavor watches furiously from the bleachers as Shoto tells his team he never uses his left side in combat.

Endeavor continues watching the Sports Festival while Shoto and his team battle Team Midoriya for the ten million points that would win the Cavalry Battle. He notes that Izuku Midoriya is exploiting Shoto's weakness by keeping to his lest side, and says Shoto is foolish for allowing his opponent to do so. During the intermission following the Cavalry battle, All Might greets Endeavor in a stairwell.

All Might says that they have not spoken to each other in ten years and he wants to catch up. Endeavor angrily tells him to get lost and to stop acting like old friends. As Endeavor leaves, All Might says that Shoto was able to perform well using half his power and asks for advice on how to raise the next generation of heroes. Endeavor dismisses his request and states Shoto a hero that surpasses All Might and even though he is going through his rebellious phase. He walks away after disconcerting All Might by saying it is the reason he "created" Shoto.

Prior to the final round, Endeavor confronts Shoto before his match with Hanta Sero. He berates his son, telling Shoto that he could have easily taken first in the first and second rounds of the festival had he used his flames. Endeavor reminds Shoto that his purpose is to surpass All Might and that unlike his siblings, Shoto is his greatest masterpiece. This only angers Shoto, who replies that he will not give Endeavor the satisfaction and only use his mother's Quirk. As Shoto excuses himself, Endeavor tells him that even if that works for the festival Shoto will eventually find the limits of that power.

Endeavor encounters Izuku on his way to face Shoto in the second round of the finals. He tells Izuku he was impressed with his performance against "the brainwashing guy" and notes his Quirk is similar to All Might's. As Izuku tries to excuse himself, Endeavor tells him Shoto has a duty to usurp All Might and this next match will prove to be an excellent benchmark. He asks Izuku to hit Shoto hard, and to do his best not to disgrace either of them. He apologizes for interrupting Izuku and prepares to leave, but is halted when Izuku states he is not All Might. Izuku goes on to say that Shoto may be his son, but he is not Endeavor. Endeavor is slightly annoyed, and goes to the tournament arena to watch the match.

Once Shoto finally ignites his flames during his battle with Izuku, Endeavor explodes with wicked excitement and satisfaction. He is ecstatic to see his son has decided to use his left side and approaches the edge of the stands, shouting, proudly that Shoto will fulfill his ambitions.

Afterwards, Endeavor meets Shoto in the corridor. He tells Shoto that he needs to gain more control of his fire, and that he is proud of him for using it at all. Endeavor goes on to say that after he graduates, he will allow Shoto to work alongside him.

However, Shoto says that he cannot change so easily and has not rescinded his disavowal of him. Shoto states that the only reason he used his fire power was because for a split second he completely forgot about Endeavor, and then walks away saying that perhaps he no longer needs his father. Endeavor watches begrudgingly as Shoto defeats Iida using only his ice, pondering why Shoto feels the need to keep holding back.

Vs. Hero Killer Arc
For the draft following the U.A. Sports Festival, Endeavor sends Shoto an internship opportunity at his agency. Shoto notices his father's name among his offers. Endeavor is pleasantly when Shoto actually chooses his agency to intern with during the week following the festival. He questions if Shoto has finally decided to follow him, but his son refutes that and states he will make his own path. Endeavor immediately directs Shoto to get ready to leave so he can show him what it means to be a hero.

They travel to Hosu, Tokyo in hopes of finding Hero Killer: Stain. When chaos erupts in the city, Endeavor instructs Shoto and his sidekicks to follow him into battle. Shoto stops after receiving a message on his phone, prompting Endeavor to yell at him. Even so, Shoto leaves and asks Endeavor to send heroes to a specific location after he has handled the situation.

Endeavor eventually happens upon Gran Torino fighting against a Nomu. He claims that he will handle the creature himself but is surprised when his initial attack does not instantly KO it. The Nomu uses its Quirk to shoot flames back at Endeavor, but he is unimpressed. Gran Torino warns Endeavor that Nomu may have multiple Quirks, and takes it upon himself to defeat it. Endeavor is impressed with the old man, and asks him to go to the location Shoto gave him earlier. Gran Torino says that they should restrain the Nomu and aid the other heroes, but Endeavor states that he alone will be sufficient.

As the situation with another Nomu fighting against the Pros worsens, Endeavor arrives to save them. He punches away Nomu and breaks its arm before it crushes a female pro. He notices the Nomu has super regenerative abilities and decides to burn away its head to defeat it in their next scuffle, stating that incinerated cells cannot regenerate. The third Nomu flies away with a hero in its talons, prompting Endeavor to tell the other pros to go to where Shoto is so he can chase it himself.

Endeavor manages to injure the winged Nomu using his Quirks various applications, including scaling a wall and creating a flaming spear to pierce its head. It drops the hero, but continues to flee. Endeavor chases the Nomu until he arrives to a scene where Stain has just killed it. Recognizing the Hero Killer, Endeavor challenges him, but Gran Torino pleads for him to wait as Stain still has Izuku hostage. Stain's mask falls off and he yells that Endeavor is another false hero. Stain goes on to state that only All Might will kill him, and releases a malefic aura that makes even Endeavor take a step back. After Stain suddenly stops, Endeavor notes that he has lost consciousness.

In the aftermath of the incident in Hosu City, Endeavor is given all the credit for Stain's defeat. So Shoto and the others would avoid punishment for using their Quirks illegally to fight the Hero Killer.

Hideout Raid Arc
Following the abduction of Katsuki Bakugo by the hands of the League of Villains, Endeavor is recruited by Naomasa Tsukauchi. Detective Tsukauchi assigns Endeavor to the Hideout Raid Team, a task force assigned to rescue Katsuki from the villain's hideout in Kamino Ward. Endeavor meets with the Police alongside Edgeshot, Best Jeanist, Tiger, Gang Orca, Kamui Woods, Mt. Lady, and All Might for a strategy meeting.

Prior to the infiltration, Endeavor complains about cleaning up U.A.'s mess because he's a busy man. Best Jeanist tells him to settle down his ego and to remember that they're both U.A. alumni. That night, Endeavor sets up a perimeter around the villain's hideout with the police.

All Might, Edgeshot, Gran Torino, and Kamui Woods storm the hideout and restrain the villains. Endeavor complains that Edgeshot got to rush in while he remains posted outside. Naomasa explains that the Police needs Endeavor in case any criminal escapes the hideout.

Suddenly, a black liquid portal sends multiple Nomu to the hideout. Endeavor and the Police Force are unable to help the heroes inside as the villains and Katsuki get warped away.

Endeavor angrily asks Naomasa why the situation has spun out of control. Noamasa believes that Best Jeanist and his squad were compromised at the Nomu factory. All Might defeats the Nomu inside the building and comes outside to confront Endeavor. He asks Endeavor if he has the situation under control. Irritated, Endeavor claims he's not having any trouble and tells All Might to leave and go after the villains.

After apprehending all the Nomu, Naomasa asks Endeavor, Edgeshot, and Kamui Woods to support All Might. Endeavor reaches the destroyed remains of the Nomu Factory and attacks All For One with a stream of flames before the villain kills All Might. All Might has entered his weekend state and Endeavor is upset by the sight of All Might's body. Endeavor recalls always trying to catch All Might, but always being unable to. Endeavor yells at All Might, demanding that the Symbol Of Peace fight and show everyone why he's the better hero.

All For One interrupts and tells Endeavor to leave if he's just going to encourage All Might. Edgeshot attacks All For One and tells him the heroes are there to assist. Endeavor and Edgeshot work together to against All For One while Kamui Woods saves Best Jeanist and the other injured members of the Hideout Raid Team. The others heroes encourage All Might despite his appearance and All For One grows tired of the sentimental talk. The villain uses a giant air cannon to blow Endeavor and Edgeshot away so that he can fight All Might one on one.

All Might ultimately defeats All For One and is forced to retire in the aftermath. Enraged, Endeavor returns home and destroys his own training hall. Without All Might around, Endeavor must become the new No.1 hero. Endeavor refuses to accept the rank of number one in this manner, enraging him and leading him to set his training hall on fire.

Remedial Course Arc
During the Second Provisional Hero License Training Exam, Endeavor furiously enters, thanking All Might for looking after Shoto. He then demands to have a proper chat with All Might. Endeavor along with All Might and Present Mic enter the room where the training was being held, and Endeavor shouts Shoto's name to encourage him and gains the attention of everyone there. Everyone in the room were merely curious as to why he was there, but they grew ecstatic upon noticing All Might with him.

Endeavor asks the former Number One Hero what the Symbol Of Peace is, telling him about how he became the Number Two Hero at the young age of 20 but immediately knew he would never beat All Might, which is why he entrusted everything with Shoto. In response, All Might states that he always believed that the country needed a symbol to be their beacon of light, and in doing so he ignored the people around him, such as his former sidekick. All Might tells Endeavor that he knows his struggle of filling in his spot as the Number One Hero and tells him he does not need to follow in his footsteps to become the same symbol but find his own way of doing things instead.

Pro Hero Arc
It is time for the broadcast of the JP Hero Billboard Chart; this announcement is being held at Kamino for its importance and is special for the fact that All Might will not be on the chart for the first time as well as the top ten Heroes themselves appearing on stage for the presentation of their rankings. The new Number One Hero is revealed to be the same Hero who temporarily received the ranking; it is none other than the Flame Hero Endeavor who is wearing a new Hero costume.

While speaking, the new Number Two Hero, Hawks, asks Endeavor what it is like to be the Number One Hero, but receives a glare from the Flame Hero. Remembering what All Might advised him, Endeavor says one thing; to just watch him. This surprises the Heroes in the stadium as Hawks claps.

Back stage, an angry Endeavor confronts Hawks and is not too pleased with his behavior. Hawks convinces Endeavor that he was simply trying to make an impact so that Endeavor could look better. Hawks reveals that he was never an All Might fan and never wanted to be like him but his retirement was a big shock to him. Hawks believes that society does not need an icon Hero like All Might but a leader with a mental fortitude to support them all, believing that Endeavor has such a quality and is impressed by him. Although he is not able to tell if Hawks is being truthful, sarcastic or mocking him, Endeavor wonders why Hawks does not become this leader, to which Hawks admits that he would rather be lower in the rankings so that he would have more freedom. Unimpressed with Hawks' immaturity, Endeavor bluntly states his displeasure for Hawks and ends their conversation, telling him to apologize to everyone else.

As Endeavor walks away, Hawks tells Endeavor the reason he wanted to talk to him; in his area the number of concerning sightings has been making him worry and would like to team up with the Number 1 Hero. These sighting have to do with Nomus, which catches Endeavor's attention.

While walking the streets, a villain is struck down by Hawks' black feathers. As he struck down Teruo, Hawks' is telling Endeavor about a restaurant to eat at so that they can discuss business. A dog is about to get run over by a truck but Hawks' black feathers carries the dog to safety, all the while Hawks is busy occupied with his talk with Endeavor. Soon, the public takes note of Hawks' rare appearance and some of them take photos with him while Endeavor nonchalantly stands by. The people take notice of Endeavor but are reluctant to make contact with him; one kid bets his friend to ask for Endeavor's autograph. Seeing this, Endeavor welcomes this and allows the kid to approach him. However, the kid is taken aback by Endeavor's new attitude and believes that him being a gruff and angry Hero suited him better and shies away as his friend apologizes for him, while the event leaves Endeavor confused.

At the Umai Building, Hawks tells Endeavor that after U.A's Sports Festival he sent an offer to his son Shoto. However, Hawks is happy that Fumikage was the one who ended up coming since Shoto failed the Provisional Hero License Exam and having that would have ruined his image, much to Endeavor's anger who finds it strange that Hawks has knowledge of that despite not being a U.A graduate. Having had enough of the useless talk, Endeavor wants to know about the rumors Hawks has been hearing.

Hawks knows that the League of Villains puppets, the modified humans called Nomus, were stored in a facility in Kamino Ward but after they were captured along with All For One they have rarely appeared. However, Hawks isn't able to confirm that the rumors are true, which infuriates Endeavor who tries to leave. Hawks informs Endeavor that the rumors isn't just in his area but the entire country as he has heard it from wives gossiping or school children chatting on the way home. Hawks secretly launched an investigation with the Police Force but they came up dry and after investigating himself by flying throughout the country, all he heard of was rumors. Although never managing to find proof, Hawks, after hearing that everyone knows about Nomus, believes that someone is going around spreading these rumors to propagate the public and knows this to be true because the villain they encountered on the way was influenced by a reprinting of Destro's autobiography.

Hawks desires for Endeavor to become a leader that can lay these rumors to rest and tell the populace to take it easy. Hawks wants to live in an ideal world where all Heroes can take leisure in their work without ever stressing out, wanting Heroes to have more free time. Suddenly, Hawks and Endeavor notice that something is flying to them; it is the intelligent Nomu, High-End, who is flying towards them. The waitress comes in as Hawks protects her and Endeavor tells the Number Two Hero to evacuate the building. High End smashes in and asks which of them is the strongest. Endeavor notes that the rumors were true and is glad that this was well timed.

High-End prepares to attack but Endeavor takes the initiative first by attacking with Brilliant Scorching Fist: Jet Burn, a blast of fire that sends High End out of the building and damages it. Endeavor takes flight by propelling himself in the air with his fire. Endeavor plans to show the Nomu what is means to be the Number One Hero.

Endeavor continues to face off against High-End while Hawks is surprised that Endeavor can fly to which Endeavor considers it "not falling" and warns him to not underestimate the Nomu they are facing. When High-End starts regenerating, Endeavor sees that High-End possesses a regeneration Quirk similar to other black Nomus while the white Nomus don't have any special Quirks and assumes that the black Nomus are high quality Nomus with many powerful Quirks. Endeavor deduces High-End to be special among the black Nomus since it can speak. Resolving to capture Nomu alive for interrogation, Endeavor uses Brilliant Scorching Fist: Hell Spider, launching five streams of fire from his finger tips. Although two fire streams hit High-End, it doesn't stop its advance and lunges into Endeavor, plunging Endeavor into the building with great force and sends him to the other side of it. Endeavor releases a great flare of fire that burns High End's arm, causing it to release Endeavor from its grip. Suddenly, High-End's arm regenerates immediately and grabs hold of Endeavor once again and proceeds to smash him across the building. High-End sends Endeavor out of the building. Endeavor gets a hold of himself and takes note of High-End prowess.

Due to High-End smashing Endeavor across the building, the top half of the building begins collapsing. Hawks uses his Quirk, Mighty Wings which allows him to control and manipulate strong and flexible feathers, to get all the injured civilians out of the building first. As Hawks' feathers begin delivering the injured down to safety, Hawks himself joins the fight and launches three feathers at High End which successfully strikes its arm. Endeavor uses an advanced version of Brilliant Scorching Fist: Hell Spider and strikes High End with multiple fire streams which cuts up its body. Hawks wonders if Endeavor's move is his strongest to which Endeavor comments about it not even being close. The cut up High-End begins regenerating and comments on the fight being interesting.

High-End wonders if Endeavor stopped shooting flames since he isn't able to anymore due to a limitation. Begrudgingly, Endeavor accepts High-End's intuition about his Quirk; the more flames he produces, the more heat continually builds up in his body which raises his body temperature and causes his physical abilities to deteriorate and already knows he is inferior in power and speed to begin with. Endeavor recalls that he started a family for his Quirk's major drawback.

High End reveals another Quirk and is excited to use it on Endeavor. While evading High-End's stretching arms, Endeavor has no choice but to end the battle quickly since he cannot maintain an elongated battle due to his Quirk's drawback. Endeavor ignites viciously and releases a powerful fire blast called Prominence Burn which incinerates High-Ends body completely.

Suddenly, Endeavor sees High-End's head and neck and realizes that it tore it off to avoid completely being incinerated. While regenerating, High-End attacks the recuperating Endeavor by impaling his torso and striking him in the face, potentially destroying his left eye. The rest of the Todoroki Family watch the broadcast of the event. At U.A, a broadcast of the battle is showing; Shota Aizawa leaves Eri in No 13's care while he heads towards Endeavor's location. All Might feels powerless to help Endeavor.

Still conscious in spite of his injuries, Endeavor used his flames to lift himself and he attempted to attack High End. However, High End evaded the strike and sent the pro hero flying into a building but Endeavor refused to give in. Using his quirk once more, Endeavor projected himself after the Nomu who wondered if he had regeneration but Endeavor was aware that his body was immobile and he was only raising his flames to propel himself and needed a strategy to kill the Nomu since it was impossible to merely capture it. Hawks then used his feathers to enhance Endeavor's speed, allowing Endeavor to be launched at the villain.

Thrust by Hawks' feathers, Endeavor used the speed to attack High End sending them both through the air. He took note of the Nomu's behavior into a wild beast before noticing his regenerative powers were still active and had screamed for Hawks to give him more speed to help. After Hawks stated that his feathers are practically ash, Endeavor stated it was more than enough and used it to send him and the Nomu far from the city. With nothing to stand his way, Endeavor used a finishing move while noting he always hated the name to destroy High End for good. Endeavor emerged from the destruction and did a pose, similar to All Might's to show he was victorious. Hawks came and the two shared banter about the pose before moving to get help for Endeavor's wounds. However, they didn't get very far as Dabi appears on the scene and greets Endeavor who is confused by the latter's familiarity with him.

Endeavor recognizes Dabi through his blurred vision, shouting that Dabi was the one to kill Snatch, even though Dabi does not remember who that is. After formally introducing himself, Dabi puts up a flame wall around the two heroes. Trying to muster up some strength, Endeavor is told by Hawks to rest and that he will take care of Dabi for the both of them. However, Mirko suddenly arrives on the scene and stops Dabi, who decides to call upon an ally to fall back. As he escapes, Dabi taunts Endeavor, referring to him by his full name, Enji Todoroki and wishes to speak with him again before vanishing from the area. With the threat gone, Endeavor blacks out as an announcer shouts the Hero duo's victory.

Recovering at a hospital, a bandaged Endeavor is visited by Hawks.
