Enji Todoroki/Synopsis

History
Enji Todoroki desired to be the top hero and dedicated most of his life to it, and at age 20, he already climbed to the #2 position. However, All Might was always the most popular and the most powerful 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. Despite his efforts, he could not surpass All Might, so he decided to change his strategy and conceive a child powerful enough to fulfill his goal in his place, for that reason, Enji married Rei Himura after negotiating with her family to a Quirk Marriage in order to get his hands on her ice Quirk. Enji attempted to conceive and raise a child strong enough to usurp All Might.

Despite being an arranged marriage, Enji really did had feelings for Rei, and so the first few years went well. When he was twenty-two years old, their first son Toya was born with a fire Quirk that was even more powerful than Enji's Hellflame Quirk. Despite not inheriting his mother's ice Quirk to overcome the downside of overheating, he still planned on raising him to be a hero. He still sought a child who would inherit the Quirks of fire and ice, and Rei wanted more children, believing they could encourage each other, which ultimately led to Fuyumi's birth. Sadly, she only inherited Rei's ice Quirk, but he was still happy either way, because he felt that since Toya had more potential, he could place all his ambitions on him.

However, his plans were cut short when he discovered that Toya inherited the weak physical constitution of his mother, which made him vulnerable to heat and therefore the use of his Fire Quirk will cause degrees of burns on his skin if he abused it. No longer wanting to train him and being unable to make Toya himself quit, Enji decided to have more children hoping Toya would finally give up on his ambition to become a Hero, which ultimately led to the birth of his third child, Natsuo, and eventually Shoto. It is implied that around that time, Endeavor's obsession with conceiving the perfect child, who would inherit both his Hellflame Quirk and Rei's Ice Quirk, grew, and signs of his attitude and relationship towards his family began to worsen.

Enji eventually found his "masterpiece" in his fourth child, Shoto, pushing aside and ignoring the rest of his children who he deemed as failures. This rejection especially affected Toya, who was secretly continuing his training to regain his father's affection. Enji told him to stop because he is hurting himself, and advised him to look beyond the world of being a hero and do things like play with his siblings or make friends at school. Crying, Toya replied he can't, after all, he was the one who lit the fire in him to surpass All Might, teaching him to never give up.

When the rest of the family came to see what was happening, Toya tells his father to look at him as he charged with his flames activated at his mother carrying an infant Shoto. He was stopped before he could hurt anyone, but after Toya's outburst, Enji decided to ban the other Todoroki siblings from interacting with Shoto so he can focus on his training, and entrusted Rei to look after Toya. When Rei said that all Toya wants is for his father to acknowledge him, Enji replied that all he can show anyone is the world of heroes, to which Rei scathingly replied that he is just running away from his problems.

When Shoto was five years old, Enji began training him to become a Hero. However, the training was harsh and detestable. Rei tried to defend Shoto, saying that he was too young, but Enji refused to listen and ordered her to stay out of his way, hitting her for interfering. Enji also prevented Shoto from interacting with his older brothers and sister.

Meanwhile, Toya continued to train until one day, during the winter season, he got his Fire Quirk to grow stronger. Shortly afterwards, excited to show his father how he had developed, Toya asked him to come to Sekoto Peak the next time he had a day off. Enji, however, lifted up his shirt and saw his burned scars, angry that Toya had been training again, but his son was adamant that he was destined for greatness and determined to make his father proud of him. Frustrated, Enji ignored his eldest son's pleas and hit Rei for not stopping Toya, causing Shoto to yell at him to not bully her. Enji told his youngest son to stay out of it. Rei confessed to her husband that she couldn't stop Toya.

His worsening behavior began to affect Rei, to the point that she began to see her husband's face in her children, until one day she snapped and threw boiling water at Shoto's face. After this incident, Enji had her admitted to a mental hospital. After learning of this, Shoto angrily blamed him for what happened to his mother.

Shortly after Rei's hospitalization, Toya went back to Sekoto Peak, expecting his father to come to see his new powers, but he didn't appear. At the time, Enji thought it would only throw fuel onto Toya's ambitions, but in truth, he didn't know what to say to him. Either way, him not showing up caused Toya to lose control of his emotions, and therefore his flames, resulting in a massive wildfire. Enji could only watch from afar the massive fire in horror, knowing that Toya was there. When the fire was extinguished, Enji was amongst the mob watching the aftermath. Toya was believed to have been burned alive from the flames exceeding 2000 degrees Celsius, since only a part of his lower jawbone was ever found. Enji rushed to the scene in horror and searched for his son but was unable to find him, believing he had been killed in the blaze.

His death affected his family, especially his mother Rei, whose mental state had already been harshly affected by her husband's past abuse, and his brother Natsuo, who still considers his father responsible for Toya's demise. The family installed a Butsudan Buddhist altar in his former room after his passing and still send their prayers to him. Even Enji is seen praying at it, saying that he regrets the loss of his eldest son, going as far as to admit that he got him killed. Despite this tragedy, Enji did not let go of his ambitions, nor did he stop training Shoto in hopes of making him his successor.

Unbeknownst to Enji and his family, Toya never died, instead ending up on the path of villainy and renaming himself Dabi, due to his trauma from his father's abuse. Toya was also secretly planning to get revenge on his father, by destroying his hero career.

At some point in his career as a hero, he arrested a notorious criminal known as "Takami".

Vigilantes Beginnings Arc
Enji is involved in a series of villain attacks caused by a criminal organization known as the Villain Factory, whose goals are unknown. For several weeks, the Villain Factory was dedicated to distributing through Naruhata streets a drug known as Trigger, an illegal substance that boosts Quirks but turns its consumers in violent Instant Villains.

One day, one of the Factory's agents, Kuin Hachisuka, uses her Queen Bee Quirk to inject the drug into innocent civilians, turning them into a horde of Instant Villains, causing chaos at the streets. Suddenly, Endeavor and several other Heroes such as All Might, Air Jet, Ingenium, Midnight, Eraser Head, and several others appear and suppress all the Instant Villains in a short space of time.

Due to the villain outbreak, detective Eizo Tanuma organizes a meeting in the Police Station with some of the heroes who helped to stop the outbreak to discuss the situation and the best action to take. Eizo explains that the Instant Villains were innocent people who were turned against their will. Endeavor understands that what he means is that they are more victims than villains, so he proposes that both he and the rest of the heroes who helped stop the outbreak pay their hospital bills, and for the media to just make sure that they tread lightly when reporting this.

But Eizo not only wants that but also that the heroes do not rush when it comes to facing an Instant Villain, in case it is another innocent person. Endeavor considers his request ridiculous and argues 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 says that 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 is not present, has his reply to the problem delivered by Naomasa Tsukauchi. He stated that he will assess the situation at the scene more carefully because as heroes they must not bring harm to innocent citizens. This is in direct opposition to Endeavor's answer, greatly angering him. After the meeting ends, Suicide Bomb attacks the police station. Endeavor, still fuming over what had just transpired, decides that he's going to incinerate the villain.

However, Midnight notices that the villain's Quirk would have a volatile reaction to Endeavor's Quirk, so she warns Eraser Head, who moves the villain away with his Capturing Weapon before being hit by Endeavor, and throws him against Midnight, who defeats him with her Somnambulist Quirk and leaving him in police custody. Quite frustrated that the problem was solved by others, Endeavor leaves the police station to return to his duties.

Sky Egg Arc
On the occasion of Captain Celebrity's return to the United States, Makoto Tsukauchi decides to organize a farewell show at the Tokyo Sky Egg, inviting several of Japan's most famous heroes to participate, but Endeavor rejects the invitation considering the event absurd.

Final Performance Arc
About two years after the Sky Egg Bombing, Kazuho Haneyama, better known as the freelance idol Pop☆Step, had been kidnapped and turned into the host for the Queen Bee by the villain Number 6. Renaming herself Bee☆Pop, she used several Bomb Bees in her performance to terrorize and blow up parts of Naruhata.

On the day Bee☆Pop attacked again, Endeavor has been called to deal with her. On top of a building, Endeavor listens to Bee☆Pop's new song, "Inferno", and expresses his displeasure at the song to Detective Naomasa, who is next to him. Endeavor then angrily declares to take action and give Bee☆Pop a firsthand taste of a real inferno.

Naomasa reminds Endeavor that their goal is to capture Bee☆Pop, but Endeavor deems Bee☆Pop too dangerous, as she has a Quirk powerful enough to blow up the town with ease. Therefore, Endeavor decides that the best course of action is to annihilate her with a wide-scale assault, leaving Naomasa in shock.

Once the Flaming Sidekickers send up signal flames after evacuating the citizens in the area, Endeavor prepares to use his Hellflame Quirk without worry. Naomasa calls out Endeavor to wait, but the hero has already started his assault with his Super Move Hellfire Storm, sending an intense flaming tornado towards Bee☆Pop.

Despite launching a seemingly crude attack, Endeavor is actually controlling the tornado to minimize damage to the city. Little by little, the bees begin to explode due to the intense heat of the flames, and Bee☆Pop seems to be unable to react in time to her incoming, flaming demise.

Suddenly, Burnin yells out for Endeavor, who irritatingly cancels his attack. Angry, he yells out to Naomasa, thinking that everyone had been ordered to get out, and asks him why there is a "twig of a hero" in his way. Naomasa realizes that this "twig of a hero" chasing after Bee☆Pop is none other than the Naruhata Vigilante, Koichi Haimawari, The Crawler.

Enraged, Endeavor claims that the vigilante is nothing more than a Hero wannabe without a license, and declares The Crawler to be nothing more than another Villain.

Endeavor begins to suffer from fatigue due to overusing his Quirk. A group of Heroes come to his aid and extinguish his body with firehoses. Naomasa arrives and sees the Hero slowing down in momentum, and warns others to pull back as Bee☆Pop is headed their way with her explosions. Endeavor refuses to simply back down and instead commands the detective to deploy the Police Force, to which Naomasa replies that they will be ready. Endeavor angrily declares that he will burn everything down, including Bee☆Pop and The Crawler.

By the time Endeavor recovers from his fatigue, Koichi had managed to break Pop☆Step out of the Queen Bee's control. However, Pop☆Step had been shot with a bullet by Number 6, which would order the Bomb Bees and the Queen Bee to explode. Koichi begins to run away from Number 6 (who is pretending to be a hero named O'Clock II), with the latter pursuing him as the bees behind him explode. Up ahead, Koichi and Number 6 notice Endeavor, who is ready to resume his confrontation.

Endeavor notices that The Crawler is carrying an injured Pop☆Step, so as long as he is carrying her, The Crawler can only hop around. Endeavor states that Koichi won't get away, and that he is just an All Might hoodie-wearing punk. Koichi, realizing that he has no other choice, decides that he cannot stop nor waste time to save Pop☆Step.

Number 6, who had yet to be noticed by Endeavor, tries to use this situation in his favor by killing Koichi when he leaves the main street into an alley. To the villain's surprise, Koichi neither stops nor swerves, and instead dives right into Endeavor.

Seeing The Crawler darting straight towards him, Endeavor starts shooting fireballs at him, to which Koichi dodges as best he can. Number 6, seeing that things aren't going the way he wants, considers announcing his presence to Endeavor, as he wouldn't get any credit for taking down Koichi otherwise.

At one point while dodging, a fireball causes Koichi's hood to fly up. Enraged by seeing the antennas, which resemble All Might, Endeavor uses his Super Move, Hell Minefield. The ground begins to explode from the attack, forcing Koichi and Number 6 to jump and dodge the ground level attack. Number 6, while in mid-air, thinks he has managed to get to safety, but then Endeavor lets off a huge explosion, which takes out all of the bees.

Number 6 realizes too late that Endeavor's move is a two-folded attack and begins to get burnt in mid-air. Meanwhile, Koichi manages to float above the flames thanks to his Quirk Slide and Glide, and the energy at his feet begin to transform, allowing the vigilante to blast off and fly into the sky, leaving everyone dumbfounded.

With no intention of letting them escape, Endeavor hurries towards the place where he saw The Crawler land. Once there he finds Midnight holding an unconscious Bee☆Pop in her arms. With her are her sidekicks and as well as a trio of young men. Midnight explains to Endeavor that the villain Bee☆Pop has been captured and that she urgently needs medical care. Endeavor then asks her about The Crawler and Midnight replies that he managed to run away.

Endeavor ponders for a few seconds and allows them to take Pop to the hospital. He is sure that there is something bigger in the whole thing, and that Kazuho may have answers, so he needs her alive to be able to interrogate her. When he is left alone in the alley, he tries to find some clue about the vigilantes but he finds that there is no one there and leaves the place, but not before crushing a water pipe to cool his fire down, frustrated that The Crawler has managed to escape. In the aftermath of the incident, Endeavor is credited for taking down Pop☆Step, although his actions were met with mixed reactions by the public.

Entrance Exam Arc
Endeavor's photo is posted on 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 that 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 left 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 will be a hero that will surpass All Might 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 that 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 Tenya 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 surprised 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 City 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.

My Hero Academia: Two Heroes
While he does not appear in person, it is revealed that he was one of the Pro Heroes invited to I-Expo, but he instead sent Shoto to represent him.

Hideout Raid Arc
Following the abduction of Katsuki Bakugo by the hands of the League of Villains, Endeavor is recruited by Naomasa. He 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. Naomasa 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 can attack All Might. All Might has entered his weakened 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. He 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 against All For One while Kamui Woods saves Best Jeanist and the other injured members of the Hideout Raid Team. The other 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, 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 Remedial Course for the students who failed the 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 to 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.

Endeaver later congratulates Shoto after finishing for the day, and tries to pat his son on the head, though Shoto gives him the cold shoulder. Undeterred by this rejection, Endeavor simply tells his son that he would try to be a better hero and man that Shoto could be proud of. Seeing Endeavor's change of heart, Inasa wills himself to approach the hero and tells Endeavor that he will be cheering him on; Endeavor thanks Inasa for his support.

Pro Hero Arc
It is time for the broadcast of the Hero Billboard Chart JP; 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 he would like to team up with the Number 1 Hero. These sightings have to do with Nomus, which catches Endeavor's attention.

While walking the streets of Fukuoka, a villain is struck down by Hawks' red feathers. As he strikes down the villain, Hawks tells Endeavor about a restaurant they can eat at so that they can discuss business. A dog is almost run over by a truck but Hawks' red feathers carry 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 boy bets his friend to ask for Endeavor's autograph. Seeing this, Endeavor welcomes this and allows the boy to approach him. However, the boy 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 aren'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 strike panic into 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, Hood, who is flying towards them. The waitress comes in as Hawks protects her and Endeavor tells the Number Two Hero to evacuate the building. The High-End Nomu 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.

Hood prepares to attack but Endeavor takes the initiative first by attacking with Flashfire Fist - Jet Burn, a blast of fire that sends Hood 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 it means to be the Number One Hero.

Endeavor continues to face off against Hood while Hawks is surprised that Endeavor can fly to which Endeavor responds that he considers it "not falling" and warns him to not underestimate the Nomu they are facing. When Hood starts regenerating, Endeavor sees that he 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 that the Nomu to be special among the black Nomus since it can speak. Resolving to capture Nomu alive for interrogation, Endeavor uses Flashfire Fist - Hell Spider, launching five streams of fire from his finger tips.

Although two fire streams hit Hood, it doesn't stop its advance and it 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 Hood's arm, causing it to release Endeavor from its grip. Suddenly, Hood's arm regenerates immediately and grabs hold of Endeavor once again and proceeds to smash him across the building. The High-End Nomu sends Endeavor out of the building. Endeavor gets a hold of himself and takes note of the creature prowess.

Due to Hood smashing Endeavor across the building, the top half of the building begins collapsing. Hawks uses his Quirk, Fierce 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 Hood which successfully strikes its arm. Endeavor uses an advanced version of Flashfire Fist - Hell Spider and strikes Hood with multiple fire streams which cuts up its body. Hawks wonders if this move is Endeavor's strongest to which Endeavor comments about it not even being close. The cut up Hood begins regenerating and comments on the fight being interesting.

To prevent any other heroes from interrupting his fight with Endeavor, Hood spawns several minor Nomus to deal with them, while regenerating his body completely. The High-End Nomu wonders if Endeavor stopped shooting flames since he isn't able to anymore due to a limitation. Begrudgingly, Endeavor accepts Hood'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 he 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.

Hood reveals another Quirk and is excited to use it on Endeavor. While evading Hood'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 Hood's body completely.

Suddenly, Endeavor sees Hood's head and neck and realizes that it tore it off to avoid completely being incinerated. While regenerating, Hood 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.

Still conscious in spite of his injuries, Endeavor uses his flames to lift himself and he attempts to attack Hood. However, the High-End Nomu evades the strike and sends the pro hero flying into a building but Endeavor refuses to give in. Using his quirk once more, Endeavor projects himself after the Nomu who wonders if he has regeneration but Endeavor was aware that his body was immobile and he is only raising his flames to propel himself and needs a strategy to kill the Nomu since it was impossible to merely capture it. Hawks then uses his feathers to enhance Endeavor's speed, allowing Endeavor to be launched at the villain.

Thrust by Hawks' feathers, Endeavor uses the speed to attack Hood sending them both through the air. He takes note of the Nomu's behavior which is similar to that of a wild beast before noticing his regenerative powers were still active and screams for Hawks to give him more speed to help. After Hawks does so and says that his feathers are practically ash, Endeavor states it is more than enough and uses it to send him and the Nomu far from the city.

With nothing to stand in his way, Endeavor uses an enhanced version of Prominence Burn, dubbed "PLUS ULTRA Prominence Burn," noting he always hated his old school's motto, to destroy Hood for good. Endeavor emerges from the destruction and strikes a pose, similar to All Might's to show he is victorious. Hawks comes and the two share banter about the pose before moving to get help for Endeavor's wounds. However, they don'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.

Two days later, Enji is visited by Recovery Girl and Enji is able to avoid dying from his injuries through surgery as well as Recovery Girl's healing, which also saves his eye. However, he is left with a large scar on the left side of his face. Enji and Hawks leave the hospital, and Hawks apologizes to Enji for his injuries.

Enji says that his injuries are his own responsibility, and asks Hawks if their encounter with Hood was truly a coincidence. Hawks, flustered by Enji's question, attributes the attack to their high profile presence in the area. Enji leaves as Hawks tells him to get some rest.

Arriving at his home, Enji sees Fuyumi, Natsuo, and Shoto eating a meal. Fuyumi happily greets her father as he walks in, and congratulates him on his win against Hood. Shoto sarcastically compliments his father's new scar as he and Natsuo continue to be unenthusiastic around him as Fuyumi becomes frantic and Enji voices he can hear her.

Natsuo, unable to handle the tense situation, gets up to leave the room. Enji stops him and tells his son that if he has something to say, he can just say it. Stirred on by this, Natsuo unleashes his feelings onto him. Enji remains silent as Natsuo tells him that even though his mother and sister have seemingly forgiven him, he sees that he is still the same person who neglected his children and left them to listen to their mother screaming and brother crying. Natsuo then mentions their other sibling, Toya, and that just because Enji defeated a powerful villain, does not mean he has made up for what he has done. After Natsuo's rant ends, Enji calmly responds that he is going to face his past and atone for it.

These words are met with disgust and surprise by Natsuo who leaves as Fuyumi panics, recounting the events that led up this moment and frantically talking to Shoto that she was really happy at the progress she thought was being made and they might be family. A recap of witness testimonies from the battle plays on the television, with focus given to a particular boy who screamed encouragement from the crowd that watched the battle, which led to the crowd cheering Enji to win. Enji remembers the boy, and realizes that the cheering and motivation he received meant a lot to him.

Shoto catches his attention and tells him that Endeavor the hero is amazing, but while he agrees with everything Natsuo said, he still wants to see what kind of parent Enji will become. Shoto also tells him that he understands that a small amount of encouragement can completely alter someone. Hearing this, Enji recalls his brief talk with All Might after his retirement and strengthens his resolve to work towards the future of his family. He apologizes to Fuyumi and admits he used the wrong words with Natsuo just before.

Joint Training Arc
After taking down a wheeler villain and saving a group of children, Endeavor tries to contact Shoto while Onima informs him that they are received another requests for team-up. Endeavor orders him to compile to list of the request, being more interested checking his messaging app but receives no reply from his son. Only having his messages marked as read by Shoto.

Internally, Endeavor gives his thanks to Fuyumi for helping him to register Shoto's account, as he wants to tell him something about the technique he tried to teach him years ago, although his son has ignored all his messages so far despite his efforts to change from his past self.

Thinking back on how he treated Shoto when he was younger, regrets that he had ignored his son's own will. Frustrated for not getting any replies, Endeavor yells Shoto's name while engulfed in flames. Onima suggests that Shoto is probably in class at the time, while Kido expresses concern about his mental state.

Later, while handling a thug, he receives a call from Shoto, Shoto asking to learn about “Flashfire Fist”, much to his delight.

My Hero Academia: Heroes: Rising
One winter night, authorities were alerted of a cargo being transported by the League of Villains, prompting Heroes to try and catch the villains.

At the end of a turn is a roadblock, where a group of Heroes and Endeavor wait for the League's armored truck to arrive. Dabi sees Endeavor and blasts off blue flames at him, and the latter uses his Flashfire Fist - Jet Burn, with both attacks colliding and canceling each other out. Shortly after, Dabi lets out a massive blast of his flames, to which Endeavor counters with his Prominence Burn. The move overpowers Dabi and engulfs the truck, causing the villains to melting, revealing them to be double created from Twice's Quirk. The truck reels of a cliff.

Endeavor descends to study the cargo that the League was supposed to deliver, finding that Hawks is already there. Endeavor blames him for not helping out, to which Hawks replies that he had just arrived. Endeavor asks about the League members, and Hawks answers that they were only copies made from Twice's Quirk. When examining the contents of the truck, they find that the life support tank is empty. Hawks suspected that the tank was carrying a new kind of Nomu, but later believes that it is something else.

In the aftermath of Nine's Invasion on Nabu Island, Endeavor goes to the island to aid Class 1-A, and embraces Shoto as he is revealed to be alright. Shoto, however, isn't pleased.

Endeavor Agency Arc
After the Hero Course's Christmas party, Shoto offers Izuku and Katsuki positions at the Endeavor Hero Agency for the internship. They accept with approval from All Might and prepare for their internship.

The students meet with Endeavor on an overpass in the city. Endeavor looks seemingly happy to see them, but it was a facade and he quickly shows his annoyance at having Izuku and Katsuki as trainees, as he only begrudgingly accepted their offer cause he just wanted to work with Shoto. Katsuki says he always thought of Endeavor as being “cringey”, but he can let that slide if it means learning how the Number 1 Hero operates, causing Endeavor to shout at Shoto for not choosing his friends better.

While they walk down the street, Izuku thanks him for letting them do their work study with him; making Endeavor thinks back the words that Izuku said to him at the Sports Festival, about “Shoto’s not him”, which he repeats outloud. Suddenly, Endeavor runs off telling them that he only cares about interning Shoto, as he jumps off the overpass, telling them to stand back and watch as he flies off. He looks back to see the three students are right behind him. Izuku asks him for his instructions. Endeavor repeats his order to stay behind him.

The three students soon chase Endeavor through the city, but Endeavor, using Flashfire, is too fast for them to follow. In a business district, a villain called Starservant was causing havoc with his Glass Manipulation Quirk and had just launched a super move, Enlightened Fallen King sending a giant ball of glass flying down the street.

Endeavor flies in and destroys the glass ball with Flashfire Fist, then confronts Starservant, who runs away. As Endeavor gave chase, Starservant led him through an alley where he had three minions ready to ambush. The ambush fails as Izuku, Katsuki, and Hawks arrive and take down the minions, allowing Endeavor to catch Starservant.

As the police arrive to take Starservant away, he starts saying that Endeavor is the root of the darkness that will consume the world, which seems to have some impact on him. He then asks Hawks why he was here. Hawks responds by promoting the Paranormal Liberation Front's book, saying it is a good read. Endeavor is taken aback, possibly under the impression that Hawks had defected to Destro's ideology.

Once at his agency, Endeavor leaves the three students with the "Flaming Sidekickers," while he locks himself in his office to read the book Hawks gave him. Endeavor noticed that there is something unusual about Hawks' expression while he is offering him Destro's autobiography. Hawks gives him the book asking him to make sure he reads it well, especially the lines that he underlined.

In doing so, Endeavor understands the encrypted message in which Hawks warns him about a threat that will attack within four months. Remembering then a conversation he had with the Public Safety Commission President, who asked him to help students to gain experience fighting Villains, Endeavor finally understands what he has to do. He leaves his office and tells three students that he will train them personally.

Later, at the agency's gym, Endeavor wants Izuku and Katsuki to talk about themselves and ask them what they want to achieve. Izuku is the first to talk, saying he wants to be able to control his power and use it with maximum performance. Also, recently his Quirk has "manifested" in a different way, and wants to use this new power as a weapon.

Endeavor recalls the conversation he had with him, before his battle against Shoto in the tournament of the U.A. Sports Festival. Endeavor empathizes with him since, like him and his sons, he has a Quirk that's able to hurt himself and tells Izuku that he is like them. Izuku is confused by his words. Then Endeavor asks Katsuki what he wants to achieve, and he replies that he already has a powerful Quirk and a great mastery with it, and he just wants to find out what it is that he lacks in order to surpass the No. 1 Hero.

Endeavor concludes the presentations and wants to start the training already, but Shoto tells him that he didn't ask him. Endeavor is sure that his goal is to master the Flashfire Fist but Shoto is straight up with his father about what he thinks, saying that he comes to his agency is to use him and learn from him, but his true inspiration is All Might and tells him to stop trying to act like a father figure with him in front of his friends. Endeavor grieves at Shoto’s words. He thought Shoto was finally starting to forgive him, but he is wrong. After accepting this, he decides to start the training.

Endeavor goes out with his three interns. He tells them the three fundamentals of Hero Work: Rescue, Evacuation, and Battle. With his training, they will not only improve their skills and Quirks but also detect and stop the slightest threats before anyone else, keeping the damage to a minimum. Endeavor ends the lesson by telling Izuku, Shoto, and Katsuki that, during the winter break, their task is to beat a villain faster than him, even if only once.

Endeavor goes immediately into action upon receiving a warning call, being followed by his trainees. He captures without breaking a sweat a hit-and-runner who was driving a motorcycle through the alleys. Endeavor tells his trainees that they are slow. Katsuki tries to justify himself with the excuse that his power takes longer to activate in the winter. While the Sidekickers deal with the villain, Endeavor blasts off again, with the students following suit.

Endeavor instructs them that, although sometimes they can receive help from others, as he received it from Hawks in his fight against the Nomu, a Hero have to learn to do everything on his own. Then he says to Katsuki that working as a hero, excuses like his previous one don’t matter when he shows to late, because he fails to save people. He accentuates this point after saving some people from being run over by a truck. While Izuku helps out the civilians, Endeavor gives Shoto and Katsuki the same assignment, to learn how to store up and condense their powers, to be able to release it at maximum impact until they can do it without thinking.

During a break, Endeavor asks Izuku if he can control his maximum output without thinking, which he says yes with Full Cowling, however he still needs to think for Air Force. Endeavor advices him to to forget about his “secondary” ability for now and focusing only on using Air Force. When Izuku asks about parallel processing, Endeavor talks about how everyone uses parallel processing subconsciously, using the example of a driver who through practice was able to do everything without thinking. He tells him that first he needs to learn how to do two things at once without thinking, and once he succeeds, to throw in another thing.

Endeavor concludes telling them that in the U.A. it’s where they acquired knowledge, but it will be during his Work-Studies with him where those lessons will really take root in them, stating that they can practice and fail as much as they want, as it won’t have any effect on his work.

Throughout the week, the students try to capture a villain before Endeavor, but even so the Pro Hero always manages to get there first. Despite this, the three of them have high spirits and are sure that they will eventually surpass him. After returning from a patrol, Endeavor returns to his office, and gets a call from his daughter Fuyumi who, knowing that Shoto and two of his classmates are working with him, she's invites them all for a big dinner.

Endeavor proceeds to reflect on everything that’s happened regarding his family. He recalls his recurring dream in which he sees his wife and children happily sitting around the dinner table, but he is not with them. He has another internal monologue that he only approaches his family as a hero, not as a father. He thinks about pushing Shoto away from his siblings, pushing his wife to her breaking point, resulting in the accident and Shoto’s complete disdain for him. And yet his daughter Fuyumi, wishing he could make amends for his mistakes. Endeavor thanks his daughter for all the support she has given him.

He thinks back to a moment sometime previously when he first heard from Fuyumi about Shoto visiting Rei in the hospital. She tells him how they’ve started slowly talking and that on days when he’s busy, he’s gonna start writing letters to her. Fuyumi then says how she hopes that one day her whole family could be together again. He then remembers Natsuo’s hard hitting critiques, Shoto’s own current opinions, and All Might’s advice on knowing what reason he has to be strong. He then receives an emergency aid from the Flaming Sidekickers, and heads out.

The three spend the day patrolling the city and solving any cases they come across, with Endeavor still accomplishing the tasks first at every moment, all the while continuing to giving them advice on how to improve. As the sun sets, Endeavor thinks back on Fuyumi words, and brings Shoto, Izuku, and Katsuki over to his house for dinner per his daughter's suggestion, to Katsuki’s annoyance.

Fuyumi welcomes everyone, and informs that Natsu is there too. Dinner starts off well, with everyone enjoying the food, but then family tensions begin to show. Fuyumi reveals that Natsuo also did some cooking as well, though Natsuo states that since he over-seasoned the food, Endeavor made him stop. Endeavor apologizes for not knowing prior and wants to try some of his cooking, but Natsuo gets up and leaves, still unable to sit near his father.

After dinner, Endeavor is in charge of washing the dinnerware while Izuku and Katsuki help with the plates. Meanwhile, Shoto and Fuyumi discuss the complicated relationship with their father, with Shoto admitting that he cannot forgive him for what he did to him and his mother. Izuku and Katsuki break into their conversation, and as they collect the remaining dishes, Izuku tells Shoto that he thinks she is preparing to forgive him. He tells her that it's okay not to be able to forgive him if he wants to, but since he knows that Shoto is a kind person, he is waiting for the right moment. Both Natsuo and Endeavor overhear this discussion.

Enji walks into another room, to put a plate of food on the Butsudan Buddist altar in their home and puts his hands together in prayer. He once again monologues what he can do for them at this stage and having the same dream. He looks at a picture of his eldest son, Toya, and wishes he was here.

Endeavor comes in the dining room and tells the three boys that he'll be taking them to school. After the three thank Fuyumi for the meal, Endeavor thanks Fuyumi for her hard work, to which she accepts with a smile. As the four return to the Hero Office, Endeavor tells the three of them that he wants them to try and get stronger on weekdays and weekends if their schedule allows.

When Katsuki complains about how small the car is to which the chauffeur complains right back to Endeavor about why he picked up what he considers high school dropouts, to which Endeavor says it's because he was put up top. Endeavor soon notices a man having captured Natsuo in the road's lane lines using his Whiteline Quirk and yelling for him to come out. The driver has to swerve and maneuver to avoid running over the villain. Jumping out the car, Endeavor demands that his son be released. The man reveals himself as a villain called Ending who Endeavor recalls that he beat seven years ago and challenges him to a rematch or else his son dies.

Ending yells to Endeavor brings up under the most extreme circumstances, a hero will never kill someone. Ending, however, cites how Endeavor killed Hood and compares himself to said Nomu after the life he's led, so Endeavor doesn't have to worry about killing another "puppet". After Ending is caught off-guard by Shoto and the others, he takes the moment to attack but halts after seeing Natsuo held in the middle, not wanting to endanger him, and allowing the three students to press forward. Once the civilians are safe and Ending is defeated by Shoto, Endeavor embraces Natsuo (who was saved by Katsuki, that is also hugged much to his annoyance), grateful that his son's life is safe, he remarks internally how in one week, the three of them were able to successfully put what he had been teaching them into practice, as their growth was able to save a life.

Holding his son and Katsuki, Endeavor asks Natsuo if he's hurt, while Natsuo only mentions how hot Endeavor's grasp is. Natsuo soon breaks free of Endeavor's grasp, as Endeavor reveals that he stopped to think in that moment fearing that if he were to save him, then Natsuo would never speak to him again. Natsuo hears his father confessed that he never meant to neglect him and Fuymi all those years, but acknowledged that he failed to take responsibility by running away from them. He also acknowledges that he feels it's his own fault for Toya's fate. After Natsuo tells him he doesn't care, for he heard everything from Toya growing up and declares he will never forgive Endeavor because he doesn't see himself as kind as Shoto or Fuyumi. Endeavor states he still came out for Fuyumi and Rei's sakes and that he was trying to respect the feelings of his sister who is trying so hard to fix the family that Endeavor broke, signifying that Endeavor sees Natsuo as kind enough. Endeavor then states that it's okay if Natsuo doesn’t forgive him because he's not looking for it, he just wants to atone for his mistakes.

After Natsuo becomes teary-eyed, Natsuo tells him that Fuyumi had been so happy lately, but every time he looks at him, he thinks of everything in the past. He questions why he has to be the only one to try and proactively change and what exactly will Endeavor do to atone. Before Endeavor can respond, Ending speaks up, wailing that his 'arrogant, ferocious flame' is sizzling out. The police eventually arrive where they state Ending used a drug to enhance his Quirk, while noting that they have been decreasing in numbers on the black market. The chauffeur tells Endeavor to watch himself for this was the second person who tried attacking him the past few days while commenting that the evil in society never fades, with Endeavor saying the light doesn't fade either. Endeavor watches the interns talk with Natsuo and comments internally how good Hawks' eyes really are.

After returning home with Natsuo, Endeavor watches Fuyumi worry over her brother. Endeavor then speaks up to commend Fuyumi about the home she is trying to build for her mother to return to and voices how all he could do was rely on her. He then declares that he will have a new house built in a more convenient location for her and Natsuo where she can welcome their mother back to. When Fuyumi questions what he'll do, Endeavor reveals he intends to stay at the abode and live alone, as he realizes that the only thing he can do to help his family for now is to take himself out of the equation.

My Hero Academia: World Heroes' Mission
During the Work-Studies, the World Heroes Association contacts the Endeavor agency for a overseas mission, but first they must check if Izuku, Shoto and Katsuki are qualified to participate in it. For this reason, Enji takes his trainees to a facility to test them: Each one of them must land an attack on him within a time limit of three minutes, those who do not succeed will stay at his home.

Once the test begins, the three students attack Enji, but the veteran hero easily overwhelms them with his Hellfire Quirk. Even WH associates ask Enji to go easy on them, as they never expected to the students to be a match for him, but Enji replies to not to underestimate his trainees.

Izuku, Shoto, and Katsuki try again and this time, after better rethinking their strategy, they manage to hit Endeavor before the timer runs out. Endeavor tells them they pass, and WH associates lead them to a room where they can design special stealth suits for the mission.

It turns out that a few days ago, an anti-Quirk cult known as Humarise had caused the deaths of thousands of people by setting off a Trigger Bomb in a city. In response to this terrorist attack, the WHA had organized an international operation to raid all the branches that Humarise has in the world.

Endeavor leads the Otheon Task Force, whose mission is to storm Humarise's headquarters in the country to stop their leader Flect Turn and seize the Trigger Bombs. Enji divides the force into two teams, he will lead the one in charge of looking for the Trigger Bomb while the other team will hunt down Flect Turn.

When everything is ready they start the storm. The Humarise members in the building try to protect it, but are easily defeated and captured by the heroes. Yet despite an exhaustive search for him, none of Endeavor's force finds Flect Turn or the bombs. The results were the same in the rest of the raid so the WHA director orders all the task forces to remain on alert in the countries that were assigned to them. Otheon's team leaves to a hotel in the capital that they use as a temporary base.

Being the lowest ranking members within the team, Izuku, Katsuki, and Shoto are sent on errands for the heroes. When they return to the hotel, they see that a jewelry store is being robbed by two villains and they intervene to arrest the criminals.

Shoto and Katsuki return to the hotel and explain what happened to Endeavor, who berates them both for acting on their own to stop a petty heist when they are on a mission, and orders them to let local heroes deal with minor crimes. Then he asks about Izuku, and Shoto replies that he went after a third person suspected of helping the jewelry villains, but they haven't been able to contact him, further enraging Endeavor.

Right on cue, Izuku phones them to tell them that he and the thief had been attacked by a villain and the Otheon police for unknown reasons. As endeavor, Shoto ans Katsuki listen to Izuku's story, an agitated Clair Voyance interrupts them to show them that on the television news they are reporting that Izuku has been accused of the murder of twelve people. resulting in putting him on the Otheon most wanted list. Endeavor, like the rest of the Otheon team, is shocked by these accusations, and Shoto tells Izuku to stay hidden while they try to figure out what's going on.

Endeavor immediately goes to the Otheon Police Headquarters to demand explanations from the commissioner general, requiring him to show him the evidence that has made him accuse Izuku of being a mass-murderer. The commissioner refuses, arguing that Izuku's case is still pending. The commissioner refuses, arguing that Izuku's case is still pending, so he can talk about the investigation, especially with a foreign hero like him.

Endeavor leaves frustrated by the refusal. What the hero does not know is that the commissioner general is a follower of Humarise. It turns out that when he was separated from his teammates during the jewelry store heist, Izuku and the third thief, whose name is Rody, mistakenly took a briefcase whose contents may disrupt the cult's plans to bring down the hero society, which is why Humarise uses all his resources to get it back.

Meanwhile at the hotel, Shoto manages to deduce more or less what is happening thanks to a series of clues, and after receiving an encrypted message from Izuku indicating where he is going, he takes Katsuki with him to go to the place, asking Claire to report to his father of everything he has discovered.

Days later, Humarise hijacks all telecommunication and announces globally that they have placed the Trigger Bombs in twenty-five cities around the world, and that they will explode in less than two hours, and to attract the greatest number of heroes to the prepared trap, they indicate in which cities are found, Otheon being one of them. Endeavor's entire team immediately heads off to search for the bombs and help the terrified civilians, with Endeavor himself wondering about his son's whereabouts.

During the search, he receives a message from the WHA headquarters informing him that his trainees have found a way to prevent the detonations and that they are heading to the secret base of Humarise to defuse the bombs. Burnin suggests that they should go support them, but Endeavor tells her they don't have time and have to stay behind to deal with the bomb, putting his trust in his trainees.

Clair calls him informing that she has already found the bomb, hidden in a semi stopped in front of the Otheon Tower. Endeavor and Burnin immediately fly there, telling the rest of the heroes to gather at the building if they can. Endeavor then hears Clair scream on the comm, and before he realizes what's going on, he and Burnin are attacked by members of Humarise, stationed there to protect the weapon from the Heroes.

A pitched battle soon breaks out between the heroes and Humarise. After much effort, Endeavor manages to reach the Trigger Bomb, but since there is little time left for it to explode and release its lethal contents, he grabs the weapon and uses his Hellflame Quirk to propel himself skyward, trying to get as high as possible.

Fortunately, Izuku, Rody, Shoto, and Rody were successful in defusing all of the trigger bombs, defeating Flect Turn and the higher-ranking members of Humarise in the process. With the terrorist plot foiled, all the surviving Humarise members have arrested and the Trigger Bombs are safely removed. After waiting days for his trainees and Rody to recover from their injuries in the hospital, Endeavor and all the members of his agency return to Japan.

Paranormal Liberation War Arc
Endeavor and multiple Heroes from across Japan are rallied by the Hero Public Safety Commission, who reveal that they have info on where the recently formed Paranormal Liberation Front is currently residing thanks to Hawks. Endeavor is assigned a team of his own to raid the Jaku General Hospital. It turns out that this location is where the Nomu are currently manufactured as a result of All For One's defeat back during the Kamino Incident. As the Heroes ready themselves for the upcoming storm, Endeavor hopes that he can contact Hawks once again.

Three months later, upon reaching their destined locations, the Heroes all launch their move to take down the Paranormal Liberation Front once and for all. Endeavor leads his team to evacuate any civilians inside Jaku Hospital. While proceeding to do that, Endeavor and a few Pro Heroes discover Doctor Kyudai Garaki wandering about in a hallway. Endeavor recognizes the man as All For One's right-hand man and primary source behind manufacturing Nomu, vowing to put an end to his madness.

Kyudai attempts to flee from the Pro Heroes, only for Shota to stop him with his Capturing Weapon. Endeavor watches on as Shota and Hizashi call out the old bastard for ruining many innocent lives and now its time he'd pay for his crimes. Endeavor also notices Kyudai's appearance deteriorating due to Shota's "Erasure" Quirk. However, Mirko contacts the Hospital Raid team and reveals that multiple Nomu are starting to emerge underground. The Heroes brace themselves as the aforementioned Nomu arrive, much to the dismay of Endeavor himself. Endeavor realizes that as he watches "Kyudai" melt away, the man they just confronted was a Double from Twice's Quirk.

Thankfully, the Heroes don't have to worry about damaging the hospital once Mandalay informs the team that all bystanders have been evacuated. With that being said, Endeavor and his team take on the powerful Nomu without any hesitance. Endeavor also tells the others to try and find the real doctor's location while he's occupied with the Nomu. Soon as Mirko manages to fend off some of the incomplete High Ends released by Kyudai, Endeavor reaches the laboratory and intercepts the Woman High-End just in time for the other Heroes to show up.

Endeavor and the Heroes nearby buy time for Mirko to stop Kyudai from awakening Tomura but the Rabbit Hero becomes fatally wounded by Woman's powers. Endeavor is forced to defend himself against Woman's sudden boost but is able to withstand this tremendous power and rescues Mirko from further harm. Endeavor then cauterizes Mirko's wounds with his fire, nothing that it hasn't been five minutes since Mirko reported her status before fighting the High-Ends. A few minutes later, the other Pro Heroes manage to arrive at the scene, allowing Endeavor and his team to finish off the remaining High-Ends.

Afterwards, the Heroes are forced to flee the hospital once it starts rapidly decaying due to Tomura awakening and unleashing his true power. Endeavor carries Mirko and an unnamed Hero while trying to escape the crumbling building. Eventually, Endeavor and some of his allies survive the Decay but lose few of their close comrades. After this, Tomura orders Gigantomachia to meet him, bringing with him the League of Villains.

Endeavor decides to confront Tomura himself to prevent All For One's successor from spreading his madness across the world. First, he unleashes Hell's Curtain, trapping Tomura in a scorching inferno to which Endeavor says there is no escape from. Internally, Endeavor says that he can not let Tomura take any step further so for now, he will try to incapacitate him.

Tomura escapes the flames and tries to touch Endeavor to disintegrate him but Endeavor dodges it and counterattacks, surprised that he managed to withstand the burning burning punishment he inflicted to him effects using Super Regeneration. Then Endeavor grabs Tomura tries to incinerate him, and while doing this, he uses the communication device to inform that the others are currently engaged Tomura, and requests that the heroes who can fly to form a perimeter.

Tomura blasts Endeavor away and salvage a couple of Quirk-Erasing Drugs for future purposes. Endeavor returns to continue attacking, and despite the violent combat, Tomura seems distracted, as something inside urges him to seize "One For All", mentioning it out loud while fighting. Endeavor is confused by his words, which are captured by the communication system, reaching Izuku's ears.

Urged by this desire to get the One For All, Tomura stops fighting and walks away in the direction of Izuku after having detected him with his search Quirk. Endeavor reports that Tomura is heading to the evacuation zone and gives the proper orders. Izuku, followed by Katuski, moves away from the area so as not to put innocents in danger, and communicates to Endeavor that Tomura is after him. Endeavor asks Izuku what he is talking about, but he replies he will explain later.

While in the air, Tomura has an idea to get Endeavor out of his way and disrupt communications, which involves him combining Air Cannon with Radio Waves to release a blast that jams all the communicators. Tomura finally catches up with Izuku, and tries to steal One For All from him, but he and Katsuki are saved by Gran Torino. Eraser Head appears and uses his Erasure Quirk to cancel Tomura's powers, allowing Ryukyu to knock the villain into the air. While still in the air, Tomura brings the communicator up to his face and orders a large group of Near High-End Nomus recipient to kill anyone in sight to prevent more heroes from appearing to help.

Endeavor charges for his sidekick Kido, who uses his Traject Quirk to change Endeavor's trajectory straight up at Tomura. After reaching him, Endeavor unleashes a blast of fire but Tomura dodges to the right, though his left arm does get burned, which he says it really hurts. Endeavor realizes he didn't use a Quirk to dodge him, but his natural strength. He also notes how similar he is being able to move in the air despite having no Quirk compared to All Might.

Ryukyu flies towards Tomura but the villain slams Endeavor into her, sending them both plummeting into the ground. As a sort of mockery, Tomura stands triumphantly over them while raising his right arm in the air similarly to when Endeavor raised his left arm after defeating Hood. Endeavor tries to strike him again but Tomura dodges and moves away from him to take out Eraser Head, but he is tackled but Izuku before he can do it.

Endeavor, Izuku, Katsuki and Gran Torino constantly attack Tomura while Eraser Head continues to use his Erasure to prevent him from using his Quirks. The damage that they inflicts on him is very high because he cannot use his super regeneration. Endeacor tells Tomura that no matter how much power he obtains, the Heroes will never yield to destruction without conviction. Tomura responds by saying to Endeavor that Heroes hurt their families to help others; the exact words of his father, which surprises Endeavor. He says that if that is conviction, then he has it too.

Tomura lectures them about the flaws of the hero society, but Endeavor responds by shooting a blast of fire in Tomura's direction, sarcastically thanking him for his monologue because it gave him some time to cool down. To his shock though, Tomura jumps through the fire blast and into the air, causing Endeavor to question how he can still move.

Tomura runs in the direction of Eraser Head to neutralize him because he is the one who is causing him the most problems by making it impossible for him to use his Quirks. He is tackled by Gran Torino, but Tomura defeats him with ease, severely injuring him. Tomura continues in the direction of Eraser Head, this time being tackled by an angry Izuku and Ryukyu, who manage to contain him, allowing Katsuki and Endeavor to charge forward.

Tomura, however, digs through Ryukyu's hands carrying a couple of Quirk-Destroying bullets, and aims for Eraser Head's position. Ryukyu sees the bullets and warns the others. Katsuki is able to destroy one of them but the other bullet successfully hit Eraser head in his crippled left leg, forcing him to cuts it off before the drug could spread throughout his body. However, this causes him to blink briefly, momentarily canceling his Erasure, allowing Tomura to unleashes a shockwave to break free of Ryukyu's grip and flies straight for Eraser Head, getting rid of Ryukyu and dodging Endeavor's blow, and manages to dig his fingers into Eraser head's face.

Izuku yanks him back with Blackwhip at the same time Tomura is struck by a pillar of ice from Shoto, who just arrived, but they can't prevent Tomura from severely injuring Eraser head's face, forcing him to close his eyes due to the wounds. As a result, Tomura is successfully able to heal himself with his Super Regeneration, and he looks to the Heroes saying that as much as they delayed it, the only fate that awaits them is total destruction.

Endeavor asks his son where he was and he explains he went to help Ryukyu and the others. He also surrounds Endeavor in ice to help him cool off. Manual and Rock Lock are trying to treat Eraser Head's wounds. Tomura then announces it is time for everyone to die just as his body begins to deteriorate, as he did notices he was awakened a month before his body could adapt to contain the incredible power of All For One. Nevertheless, Tomura's regeneration finally kicks in, and he attempts to use his Decay Quirk again to finish everyone off, but Deku jumped into the air carrying everyone with Blackwhip, declaring that he will finish him with everything that he has.

Before attacking Tomura, Izuku releases the Heroes telling them to take care of the wounded. Then, knowing that even Tomura's body has a limit, Izuku begins to strike him in mid-air over and over with the One For All 100%, regardless of the injuries he suffers as a result. Endeavor tells his son to give everyone first aid, while also upset that he isn't up in the air himself fighting against Tomura.

On the ground, everyone is surprised by Izuku's display of power but Katsuki states that he won't be able to continue like this for long, so he grabs Shoto and Endeavor as he tells him to hold off on the fire until he gets him up in the air and for Shoto to cool him off as long as possible. Endeavor accepts Katsuki's plan. The three flies into the air as Endeavor tells Katsuki to aim for when Blackwhip is completely extended and when he gets up there, the two need to get back to the ground or they may get caught up in the fire.

As the three reach the fight, Endeavor grabs Tomura as he yells for Deku to get down as he incinerates Tomura with the full power of Prominence Burn. Despite being burning him alive, something snaps inside Tomura’s mind, and Endeavor gets stabbed by Tomura's Rivet Stab emitting from his back and he wonders why he won't die. 'Tomura' says something unintelligible before firing the wires at Izuku, calling him his 'little brother'. Katsuki, without even thinking, pushes Deku out of the way and received the full force of the attack.

Shoto manages to grab his father and Katsuki, while Deku, after his mind snapped with rage for what just happened, goes berserk on "Tomura", although the only thing he gets is that his nemesis puts his hand on his face and starts stealing the Quirk. But something prevents him for doing it, and both Deku and Tomura fall away from one another in the sky.

Shoto catches Izuku while still holding onto Katsuki and his father and drops them on the ground with relief that the three of them are still alive. Just as he is about to administer first aid, he, Deku, and Endeavor see Tomura holding his ground with the wires from his fingers and back. Then, he gets blasted by Nejire Chan's Wave Motion as Ingenium runs to Shoto reporting that Gigantomachia is making its way to their current location.

As Ingenium, Shoto, and Nejire Chan fight Tomura, Gigantomachia finally arrives carrying the remaining members of the Paranormal Liberation Front on his back, as everyone watches in horror. Shoto and Nejire unleash their Super Moves on Tomura to take him down as soon as possible, but Endeavor warns them of Gigantomachia's attack. Gigantomachia swats them aside with his hand and brings the now unconscious Tomura close to his back to be protected by the League members.

Endeavor runs over to Shoto and asks if he is alright. At the same time, he internally apologizes to Hawks for Gigantomachia being allowed to move at all. He knows he has to stop Gigantomachia and he needs to find his weakness, but his lungs have burnt away and are making it hard to keep moving, but he feels he must continue.

Dabi emerges from the back of Gigantomachia and greets Endeavor and Shoto as Endeavor calls him by his name. Dabi, however, asks he not be called that as he pours a liquid content on his head, washing off the black coloration dye on his white hair. Dabi then reveals that his true identity is Toya Todoroki, his eldest son whom he believed dead. His proclamation horrifies Shoto and Endeavor to their very core.

Dabi also confesses that in those moments, his pre-recorded history is being broadcasted all around the airwaves and the Internet, revealing Endeavor's darkest secrets and his abusive past on his family. Dabi reveals that his initial plan was to wait until Shoto became all big and famous before killing him, but after their father became the No. 1 hero, he thought another way to make Endeavor suffer as much as possible, as he has always wanted to destroy his life and career as a hero by crushing his dreams in revenge for what he did, without caring about putting his own family in danger, as he was also the one who sent Starservant and Ending against him.

All of this makes Endeavor think back to when Toya was still young, training him to be his successor and reach his eternal goal, until the tragic incident that caused his apparent death. Back to the present, a dumbfounded Endeavor demands that Dabi take back that 'despicable lie', but Dabi retorts that it is the 'despicable truth'.

Dabi mockingly thanks Endeavor for going strong up until now as he jumped off Gigantomachia's back aiming for him. Endeavor, still in shock, admits to himself that at the time, he kept searching for Dabi, never once thinking he was dead. Shoto, however, tries to get him to protect Deku and the others and worry about the rest later while he and Nejire Chan fight him off. Dabi descends covered in fire as he attempts to use Endeavor's Prominence Burn move.

Before he can unleash his attack, Dabi finds himself tied up with wires from the sky. He turns to face his assailant and it turns out to be Best Jeanist, who has jumped out of the plane apologizing for the delay and is ready to resume duty. Using the many wires he brought with him, he successfully binds all of the League of Villains with his Quirk, including Gigantomachia.

Dabi manages to free himself by burning the wires, clashing with his youngest brother Shoto, who reveals to him that one of the villains he sent Endeavor's way nearly killed Natsuo. Dabi, however, merely says it was a shame he didn't die because then Endeavor would have suffered more. An incredulous Shoto asks Dabi if he is insane and Dabi confirms he doesn't feel anything anymore. He starts to push Shoto back, excited at the thought of finally being able to kill him.

Three Near High-End Nomus called by Tomura approach to attack Best Jeanist and thus free Gigantomachia from his bonds, Lemillion appears and punch them away them. He, Katsuki, Ingenium and Nejire Chan protect the hero from the creatures. Meanwhile, Dabi overcomes his youngest brother and prepares to kill him with his blue flames. He looks at Endeavor, who still has a look of horror on his face, and says that he is excited at the thought of Endeavor about to see his 'puppet masterpiece' get incinerated by his 'failed experiment'. Suddenly, Izuku shoots a Blackwhip from his mouth, separating them. Izuku shouts at Dabi that his father is atoning for his past sins to become a better person, and that Dabi isn't Endeavor.

Izuku's words help Endeavor break out of his trance, just as Gigantomachia breaks free from Best Jeanist's fibers. Endeavor uses every last bit of strength he has to fly up and knock the giant back, knocking himself out as a result. Gigantomachia starts losing strength, and Mirio explains that the sedative force that the U.A. students forced fed into the behemoth minutes ago is finally working.

After this last attack, Endeavor is unconscious for the remaining battle. During the course of this, All For One's consciousness takes control of Tomura's body, and using the remaining Near High-End Nomus he manages to escape along with Spinner, Skeptic, and Dabi. The battle ends with almost all the members of the Paranormal Liberation Front arrested, but some managed to escape, in addition to which dozens of heroes and hundreds of civilians were killed. People all across the country start talking about Dabi’s video, with some wondering if it spells the end of Endeavor’s Hero career and what will happen next.

After spending two days in the hospital, Enji wakes up from his coma and is informed by the doctor that his son and the others are mostly fine. After leaving him alone, he remembers the battle he had with his eldest son and his inability to fight to protect Shoto. He admits that he's reaping everything he's sowed, and that the hero Endeavor died back there. Enji realizes that while his son might be a mass murderer, he can't fight him, and breaks down in tears starting to form in his eyes. He notices Shoto entering the room and calls his name out, though his son initially closes the door when he sees his father crying. When he reopens the door, Enji sees his two other children standing with Shoto. Enji asks if they're all ok, though Natsuo replies by asking why he's crying. Enji profusely apologizes once again, realizing that the regrets and guilt he feels right now are too late to matter. As his heart is about to shatter, he's shocked by the sudden arrival of his wife, Rei, who asserts that the rest of the family has been riddled with those same guilt and regrets for much longer than he has, and that she has come to discuss about their eldest son, Toya.

As they reminisce about Toya's childhood and growing mental instability up until the tragic night of his disappearance, Rei points out that despite Toya imploring his dad to come and see him practice his new flames, Enji didn't show up, to which he responds that he was afraid it would encourage him to train harder before admitting that he actually just didn't know what to say to him, and neither did Rei. He expresses his regrets about not having given it all up on that day, but the guilt of having indirectly killed Toya made him decide to focus entirely on Shoto's training at the expense of everything else, namely his wife's sanity and his family bonds. After that, Rei, Fuyumi, and Natsuo acknowledge that while Endeavor was the main cause, they each had their own share of responsibilities for Dabi's birth and their family rupture. Then, Rei declares that Enji has to fight Dabi, and that his family will help him get back on his feet, leaving Enji baffled at his wife's unexpected strength of mind. Following that, Shoto expresses his will to fight and stop Toya together with his father once he was done grieving, moving him to tears.

Eventually, Hawks and Best Jeanist enter Endeavor's hospital room to join their discussion. Hawks first conveys his stupor to Endeavor when he learnt of the full consequence of his old obsession with becoming the No. 1 hero, causing him some discomfort. Then he asks him about Shoto's burn scar, but Rei is the one who admits being responsible for it. Hawks then gives a status report on Japan's state for the past two days, mentioning how the remaining Paranormal Liberation Front leaders and members as well as the Near High-End Nomus are on the run, the jailbreaks, the confusion in hero management, the early retirement of several dispirited heroes, citizens arming themselves up in self-defense and the ensuing chaos, and the decision to request help from heroes around the world. Consequently, he proposes that Endeavor, Best Jeanist, and himself team up to remedy the situation, and Enji tearfully accepts. After that, Hawks asks Enji about the nature of what Tomura was after, called "One For All". When he hears that, Enji suddenly remembers Deku informing him that Tomura was probably after him.

Enji then learned the truth about One For All from All Might around the same time as Hawks and Best Jeanist. Three days later, they left the hospital and made a public announcement together. He apologetically confirmed Dabi's claims and accusations towards him, and confessed everything about his family's past, shocking and disgusting the general public. At one point, a woman from the audience spoke up to express her anger about her mother getting injured during Gigantomachia's rampage, the heroes seemingly glossing over the damage done over the past week, and their apparent lack of guilt. So Enji made her understand that at the moment, showing their own pain and suffering to the public wouldn't change anything, as putting society at ease and taking down every single villain is the only way Endeavor can atone. He then implored the audience and the entire population to direct all their criticisms and doubts not at the heroes who will be putting their lives on the line, but at him alone, and to watch only him. Eventually, the journalists asked him about the nature of "One For All", to which he replied that he didn't know anything in order to protect Deku and All Might.

Tartarus Escapees Arc
In order to track down Tomura, All For One, and the remnants of the League of Villains, Endeavor, Hawks, and Best Jeanist come up with the plan to team up with Deku and All Might, using the former to act as bait to lure out the villains. While Deku looks for more Tartarus escapees, Endeavor finds himself under fire by some low-tier villains, with one of them using a very powerful nail gun support item, which he deduces came from Detnerat. He defeats the villain with his Super Move: Ignited Arrow, as they complain that it is his fault they are even out here in the first place. Endeavor, however, says that that is why he is here, and hands him over to the police.

He meets back up with Best Jeanist and Hawks where he confirms the convicts weren't sent by All For One. The three are then confronted by a mob of protestors, calling the three of them 'hero scum' and demanding they get out of their faces. Several of them blame them for the current state society is in for letting Tomura get away and releasing the prisoners. They also reveal they know Tomura is looking for someone else, meaning the heroes are still keeping secrets from them, as well as asking Endeavor if he has seen the grieving relatives of the people Dabi killed on TV.

Endeavor talks with Jeanist and Hawks about the current situation with Deku and All Might, and how he doesn't want Deku to receive more pressure than he already has, admitting how they are using him as bait to lure out the villains even though he asked for it, but are having trouble since they have gone underground.

The Heroes proceed to discuss what the villains' have planned next, assuming the Tartarus escapees had received some orders from All For One, and therefore it is only logical that they are using the greater confusion and chaos to lay low while pursuing One For All. The three deduce that because All Might damaged All For One to the point he needs life-support to live, Endeavor confirms what Izuku said is true: All For One's top priority is controlling Tomura's body, turning Tomura into his successor would make for a new body for him, which is why he is prioritizing this task.

Shortly afterwards, Deku has an encounter with Lady Nagant, who he managed to defeat in battle, though she was soon exploded due to a trap planted within her by All For One. Hawks arrives in time to rescue her, while Endeavor follows behind, having been delayed because of the rain. He apprehends Kai Chisaki who accompanied her, and the heroes prepare to take Lady Nagant and Deku to the hospital to recover.

Before she passed out, Lady Nagant managed to reveal the location of All For One's supposed hideouts in Haibori Woods, so the heroes prepare to head there. Accompanied by The Lurkers, Endeavor arrives with the heroes to infiltrate the base, but finds it empty, only finding a hologram message from All For One sarcastically telling Deku that he took a thorny path of heroism because the more he fights the more his soul will wear down, and reveals that while in prison, he never stopped thinking about him, no longer having any interest in All Might. He gleefully tells him that it is "his turn” as the mansion explodes.

However, the heroes managed to survive, and they reconvene in a warehouse discussing their current fighting strength. Edgeshot brings up the idea of all of them banding together the other heroes and share One For All’s secret so they can create a larger network of investigations. Mt. Lady adds that following this incident with Lady Nagant, the brunt of investigating the League is falling all on Deku, and with the police dealing with their own problems and there being zero witnesses regarding the League, they should gather as many allies as they can while they still can. Endeavor, however, reminds Mt. Lady that Death Arms retired two days ago because despite keeping up the fight, he had gotten nothing but criticism and doubt, and even though there are people who believed in him. Endeavor also adds that the retired heroes are leaking information regarding One For All, and the public are getting close to uncovering the truth about Deku. Endeavor says that if the public finds out about One For All’s nature, Deku will be caught in a cycle of negativity.

Mt. Lady says that she wonders why All For One hasn’t revealed One For All himself to the public, which Endeavor responds that if he did that, they would do everything they can to keep Deku hidden, so that is the reason why he hasn’t done that. However, he admits they don’t have any clues unless they and Deku move, and all of them come to face the reality that there aren’t enough police forces and heroes to handle it all. Endeavor’s phone rings, and he sees a text from Shoto asking him to pick up. He remembers Shoto telling him to let them work together to stop Dabi and he silently apologizes, saying that he needs to wait a while longer.

The heroes then learn from All Might that Deku has abandoned him to go and fight the villains all on his own, leaving them to feel most distraught. However, unbeknownst to him, Shoto and the rest of Class 1-A were getting very impatient with his lack of response, so push forward with a plan to make use of Endeavor's U.A. alumni status to lure him over to the school so they can confront him personally.

Principal Nezu contacts Endeavor, who meets him in his office, but is surprised to see all of Class 1-A present too. Nezu informs Endeavor that he heard what they had to say and decided there was room for discussion since he is constantly getting updates himself. Shoto asks Endeavor why he has been ignoring him and if he forgot the promise they made to stop Toya together. Endeavor responds that it was Shoto's willingness that saved him, but Shoto retorts he doesn’t feel the same way without actually doing anything and asks what makes Izuku an exception.

Shoto demands to know if Endeavor is letting Izuku and All Might work together. When he says nothing, Katsuki’s suspicions are confirmed, but while he says it may have been the right call, he knows nothing about Izuku. Katsuki states that Izuku has always been crazy for never taking himself into account and insisting he is fine, citing it as the same way All Might became the Symbol of Peace. He tells Endeavor that he can't let the two of them be together, with Endeavor thinking back to when they learned that Izuku had brushed off All Might and how they don't know how else to support him from the sidelines.

Convinced of their resolve, Endeavor decides to hand the students his GPS satellite phone that can pinpoint Izuku’s location. Many of them want to help him even though their relationship has been so far school-based and declares that as Class 1-A, they will follow Izuku wherever he goes, and no matter how much responsibility that comes with One For All, they consider him their friend, and they won’t let him walk such a troublesome path all by himself.

Endeavor reveals that the outside world is in chaos right now but Nezu reassures them that they are ready. He says that he agreed to let him team up with the top three since he didn’t want to return to U.A. and that the villains were targeting him. But he reveals that he can return to school, since the minute they sent out the acceptance notifications, they all became students they will protect. Endeavor asks about the civilians' safety and Nezu tells Endeavor that the designated evacuation areas weren’t only chosen based on area, and that the school has reinforced their security "U.A. Barrier" since the Culture Festival. He assures the students that Izuku will be fine if he comes back, so they can go help him.

A few days after Class 1-A confronted Endeavor, he contacts Deku and informs him that the dates for when overseas heroes will arrive will be announced soon, which means they will have more manpower to help with the investigation. He tries to convince Deku to rest, as he knows how much he has been pushing himself, however, he replies that he can still move and he doesn't want to give the villains time to prepare. By then, Deku was already physically and mentally exhausted to the point where he is too weak after being confronted by one of All For One's villains; Dictator until Class 1-A arrived and defeated him.

Despite how exhausted Deku is, he still continues onward to fight against his former classmates while Endeavor arrives near the battle and meets up with Red Riot, Can’t Stop Twinkling, and Invisible Girl, who deliver a restrained Dictator to him. Endeavor tells them that Dictator might not be alone and to confirm the safety of the Hero-hating civilians that spread nearby, so they should help Hawks with that. Hawks, however, suggests using Best Jeanist to get it all over with.

As Endeavor sees Deku stuck in Shoto's ice, Red Riot reflects that while there isn't much he can do right now with how much he's moving around, there's still so much he wants to say to him, a sentiment shared by Can’t Stop Twinkling and Invisible Girl, who run to check on the civilians. Endeavor tells Hawks that as of now, he shouldn't interfere.

Once Deku collapses from the shock and exhaustion, he returns to the heavily fortified U.A. High where Class 1-A is confronted by angry protesting civilians. Outside of U.A., Endeavor, Hawks, and Shoto listen to Ochaco's speech before Ectoplasm lets them in, saying that everything is fine for now. Endeavor was convinced that all they ended up doing was pushing the burden onto Izuku and didn't make any progress, but Hawks says they did take a step forward. Just like how One For All is a power that links together people's hearts, so too is everyone connected here at U.A.: All Might through Izuku, Izuku to his classmates, Ochaco connecting Izuku to everyone, and with everyone thinking about each other, this can lead to the bright future where everyone will have time to laugh. As Class 1-A helps with the civilians and Izuku is escorted inside, Shoto turns to his father and tells him they’re doing it together, thinking back to Toya's face, which he agrees.

Star and Stripe Arc
Thanks to information given to All Might by Stain, which he received from Tartarus, the heroes learn that Tomura will be completed far sooner than they initially believed. Due to this, All Might puts in a request for immediate aid from the foreign heroes, which is responded by America's No. 1 Hero, Star and Stripe. Endeavor, Hawks, and Best Jeanist head out to rendezvous with her, with Endeavor speeding alongside the two outside the car, when they suddenly hear a warning call from Naomasa that Tomura has shown himself and confronted Star and Stripe.

The three rush their way toward their location, spotting the two's devastating battle from afar, however reach the location too late, with Star and Stripe being killed and Tomura escaping, unable to track him down again.
