The Rise of Endeavor and Fall of Enji
At one point in his childhood, Enji Todoroki witnessed an accident wherein his father tried to rescue a little girl from a Villain, only to end up dying alongside her. This event inspired him to become a Pro Hero, and by the time he entered U.A. High School, he chose the name Endeavor. At the age of 20, he had already climbed to the #2 position on the Hero Billboard Chart JP. However, despite all of his efforts, he could not surpass All Might. Enji realized the gap was way too big and began to hold a sense of fear and begrudging respect towards the latter. Because of this, 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 had inherited his mother's resistance to cold temperatures rather than his durability to heat, which therefore gave his body improper resistance to his own flames and would cause his Quirk to easily burn him should he abuse it. Enji stopped Toya's training in concern for his wellbeing, but Toya himself refused to quit, becoming just as stubborn as his father to become the next top Hero. With nothing he said deterring him, Enji decided to have more children in hoping that Toya would finally give up on his ambition to become a Hero. This 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, who had inherited the dual Quirk of fire and ice he so desired. This caused him to push aside and ignore 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 that 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 and that the flame inside of him won't go out.

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, his Quirk evolved and became stronger with his flames turning blue. 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, believing that he couldn't abandon them after killing his son. He soon became obsessed on training Shoto and molding him into his perfect 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
Endeavor 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, Airjet, 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.

Naruhata Lockdown Arc
Endeavor soon returns to Naruhata after hearing about the rampaging monster wreaking havoc on the city and the heroes request for aid. After the beast splits itself up into several mini bombers that begin to detonate all throughout the city, Endeavor descends from a plane above, declaring to the Buster Union team that since their specialty is concentrated firepower on a single villain, they're out of their wheelhouse and it's time for him to take charge.

Burnin warns Endeavor that due to the panicking civilians still in the city they can't do anything yet, but Endeavor states they can't sit back while the destruction continues and he'll take full responsibility for whatever happens, preparing to roast all the villains while minimizing the damage. Then suddenly, a flash appears in the sky, which Endeavor annoyingly recognizes.

In the blink of an eye, All Might blasts his way down into Naruhata past Endeavor, shooting all the mini bombers into the air in an instant. With the mini bombers in the air safely, Endeavor laments how brazen he is and that he'll get no thanks from him, unleashing his Flashfire Fist: Prominence Burn attack, completely decimating the bombers.

Alongside his Sidekicks, Endeavor begrudgingly assists in the cleanup of the Naruhata Lockdown, and a year later, overhears about The Crawler's current escapades as the American Hero "The Skycrawler."
