Enji Todoroki

Enji Todoroki (轟炎司), also known as Flame Hero Endeavor (フレイムヒーロー エンデヴァー), has the highest tally of resolved cases in history and is the father of Shoto Todoroki.

Appearance
Endeavor is a tall man with a muscular physique. He has short, spiky, red hair and a face covered in flames, masking his full face. When he turns off his flames on his face voluntarily, his stubble shows.

His Hero Costume is comprised of a black bodysuit covered in flames with white bracers styled in a ribcage pattern and flaming shin-length boots. Wrapped around his waist is a black belt with a white pouch kept at his right side while covering the top half of his face was a domino mask made of flames, with a flame mustache and a long beard.

Personality
Enji has been shown that he is a very prideful and resentful person, as seen that he hates being No. 2 Hero for so long and wants to be No 1. Since he isn't able to do it himself, he is even willing to do what ever it takes to surpass him, so he devises a plan to "create" someone who can surpass him. Enji appears to be a horrible father on account of the fact that he seems to care little for his youngest son; furthermore, Enji uses Shoto as only a "tool" to further his own desires. He even called Shoto's siblings, his own children "things" who inhabit different worlds. Enji's heartless and selfish attitude is further emphasized when he constantly abused his wife and trained Shoto to the point where his youngest son threw up, showing that he only cares about himself and his goals. According to Present Mic, Enji is usually not a sociable person.

Enji has a very violent temper, as after learning of All Might's true form he shouted in rage at the number 1 hero. This was shown again that after All Might was forced into retirement and Enji would be given the No. 1 spot by default he destroyed his training hall in a fit of rage which nearly destroyed his own home.

Endeavor's behavior does not go unnoticed by the public. While he is a hero and possesses an amount of supporters, there are those in the public who recognize his violent temper and comparing him to All Might brings anxiety to the public.

History
Enji desired to be the No. 1 hero and dedicated most of his life to that. However, All Might was always ahead of him and eventually realized the gap was way too big and began to hold a sense of fear and begrudging respect towards the latter.

Out of spite and envy for All Might's Hero ranking, Enji forced a marriage with Shoto's mother in an attempt to conceive and raise a child with a powerful Quirk in order to surpass All Might as a Hero.

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

Entrance Exam Arc
Endeavor can be seen on a billboard screen when the heroes unite to fight an unknown enemy. He is later seen in a TV ad for U.A..

Sports Festival Arc
Endeavor is mentioned when the Robo Infernos are sent to hinder the participants of the obstacle race, and Shoto wishes they had sent stronger enemies, as his "shitty old man" was watching. He is then mentioned again when Present Mic explains that Shoto is his son.

He watches furiously from the bleachers as Shoto declares that he will never use his Fire powers in combat.

Endeavor continues watching Shoto and his team battling Izuku's team, commenting that Izuku has figured out Shoto's weak spot, calling his son an idiot for allowing him to do so. After the lunch break begins, All Might greets Endeavor, saying its been a while and asks him to have tea with him.

After All Might says that they have not spoken to each other in ten years and that he wanted to give him a shout out, Endeavor replies that he can take his tea offer to some other place and tells him to go away. As Endeavor leaves, All Might stops him, saying that his son Shouto was able to show a great performance even without using half of his power. All Might then asks Enji for advice on how-to raise the next generation. Enji dismisses his request and then comments on Toshinori's attitude, finding it to be annoying. Enji states to Toshinori that he will make Shouto a hero that surpasses All Might and even though he is going through his rebellious phase, Enji states that he will definitely make it happen, then angrily walks away.

As Izuku tries to leave, Endeavor tells Izuku that his son has a duty to surpass All Might and that his match with him will prove to be an excellent benchmark for Shoto. Endeavor tells Izuku to do his best to not give him a disgraceful match. Enji prepares to leave, but stops when Izuku says that he is not All Might, to which Endeavor replies that it is obvious. Izuku then says to Endeavor that Shoto is not him. Endeavor then goes to the tournament arena to watch Shoto's second round match.

During the match between Izuku and Shoto, after Shoto finally activates his fire power side, Endeavor grins widely and wickedly with satisfaction, happy to see that his son has finally decided to rely on his fire power. Filled with joy, Endeavor walks down from the bleachers to watch the match at a closer range, telling Shoto to surpass him and realize his ambition. After Shoto wins the match, Endeavor meets with Shoto in the corridor, telling his son that he is proud of him for accepting to use his fire power and that he has become the perfect upgrade of him. Endeavor goes on to say that after he graduates, he will let Shoto become his sidekick. 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.

Field Training Arc
Endeavor's work place is listed on Shoto's personalized list of work places.

Endeavor attacks a Nomu, scorching the creature in fire, and saves the two civilians in the process. Endeavor mentions that he came to Hosu in hopes of finding Stain, but is disappointed that time was on Stain's side, referring to the attack by the Nomus. Endeavor tells Gran Torino to leave this battle to him, saying that he will deal with the creature because he is a Hero. Shoto mentions that it was Endeavor who deduced that Stain would appeared again at Hosu.

Endeavor battles a Nomu which uses an absorb-and-release Quirk to attack Endeavor with flames. Endeavor easily fends off the creature's attack, mocking its Quirk for being useless, but Gran Torino warns Endeavor to be wary of the creature as it has multiple Quirks. The Nomu attacks Endeavor with a tongue Quirk. Endeavor prepares to fight back, but Gran Torino propels and smashes into the Nomu, defeating it before Enji could fight back. Endeavor decides that his sidekicks will restrain the defeated Nomu and that Gran Torino should go to the address given to him by Shoto, and then heads towards the area where pro heroes are fighting another Nomu, noting that he alone will be sufficient.

Endeavor fights the winged Nomu and causes it to flee. He chases after it and arrives at the area where Stain has just saved Izuku and killed the Nomu. Endeavor runs towards Stain and prepares to attack him despite Gran Torino asking him to wait. Endeavor stops his attack when Stain's bandaged mask falls off. Stain, despite his heavy injuries, declares that the only hero who is allowed to kill him is All Might, exuding a bloody and malefic aura towards his opponents; Endeavor takes a step back. After Stain suddenly stops, Endeavor notes that he has lost consciousness.

Hideout Raid Arc
After Katsuki is captured by the League of Villains' Vanguard Action Squad, Endeavor is enlisted to help in the rescue operation to save Katsuki. At the Police Station, Endeavor, Best Jeanist, Edgeshot, and Toshinori are present along with a large number of other Pro Heroes and are ready to begin the strategy meeting.

Before the infiltration begins, Endeavor complains that he must help solve U.A.'s problems and notes that he has other things to do. However, Best Jeanist remarks that they would have helped since they are alumni of U.A.. The infiltration begins and Endeavor along with the Police Force and the Pro Heroes stand in front of the League of Villains' hideout, preparing to storm the place.

After All Might, Kamui Woods and Gran Torino infiltrate and apprehend the League of Villains, Endeavor and Naomasa form a parameter around the hideout. Suddenly, dozens of Noumus begin appearing around the hideout; Endeavor along with Naomasa and the Police Force begin fighting the Nomus. Endeavor and the Police Force manage to defeat multiple Nomus. All Might appears from the hideout and tells Endeavor to take care of things as he goes off to find Tomura and the League of Villains.

Endeavor along with Edgeshot and Kamui Woods head towards All Might's location after defeating apprehending the Noumus. Endeavor reaches the location and launches his flames strike at All For One, but All For One uses his blast wave attack to swat away the flames with ease. Endeavor is flabbergasted with All Might’s appearance. All For One is surprised that the dozens of Nomus he sent were dispatched with haste even though they were mediocre and should have not taken Endeavor’s No. 2 rank so lightly. Endeavor is infuriated at All Might’s abysmal appearance and begins remembering that he devoted most of his life to surpass him, but eventually realized that the gap between them was far too great and began to fear yet begrudgingly respect All Might’s muscular form. Annoyed with Endeavor and the other Pro Heroes’ interference, All For One prepares his blast wave attack again. However, Edgeshot uses his Quirk and great speed to attack, but All For One dodges the attack. Edgeshot and Endeavor attack All For One. Growing tired with the sentimental talk, All For One blasts Endeavor and Edge Shot back so that he can deal with All Might.

After All For One's defeat, Endeavor and All Might watch as All For One is placed in the iron maiden. With All For One imprisoned. Endeavor returns home and goes to the training hall. Enraged that he will have to become the Number One Hero now that All Might is out of commission, Endeavor destroys the training hall in a fit of rage, unable to accept the position of Number One Hero as he feels that he didn't earn it nor is he worthy enough.

Keen Intellect: Endeavor has extraordinary intelligence and uses it to solve cases (which is why he has the highest tally of resolved cases in history) and has very keen deduction skills, as shown when he deduced that Izuku had a very powerful Quirk and managed to deduce that in terms of strength it equals to All Might's power upon seeing Izuku use it only once. He could also determine that using his blue flame to carbonized a Noumu's head would make it so that it couldn't regenerate, showing a certain degree of knowledge in chemistry.

Endeavor was able to take on and defeat several mediocre Noumus without sustaining any damage.

Shoto Todoroki
Enji is the father of Shoto. However, their relationship is on unpleasant terms, as due to Enji's abuse and lack of care for both his own son and wife, coupled with Shoto given a burn scar due to his mother's insanity because of Enji's abuse caused Shoto to harbor nothing but bitter hatred towards him. During the Sports Festival, Shoto complained that U.A. sent a Robo Inferno as the first obstacle rather than something harder, as his "shitty old man" was watching, and when he refused to use his Fire powers in battle, saying he'd never use them in combat, as Enji watched from the bleachers. Enji only sees Shoto as a "tool" whose purpose is to surpass All Might, something Shoto deeply hates as a result. However, Shoto does at least acknowledge his father's insight and skills as a hero and chose him for his work place experience.

Shoto's Mother
Shoto's mother is Enji's wife; however, the relationship between them is far from a happy one. Enji only married her to conceive a child capable of surpassing Toshinori, showing that there was no love between them from the very beginning. When Enji began training Shoto to become a Hero, his wife tried to stop him, but Enji refused to listen and told her to stay out of his way. Enji would constantly abuse her and this led her to going insane. Enji then admitted her to hospital, but not for her own sake but rather so that she would not interfere with Shoto, showing not a shred of any form of care or compassion.

Toshinori Yagi
Ten years before the start of the series, Toshinori once had a talk with Enji and since then, they have not spoken to each other. It appears that Enji has an intense rivalry with Toshinori (one sided on Enji's side as Toshinori tries to be friendly with him). This rivalry with Toshinori is so great that Enji decided to have a child that would be able to surpass All Might. Enji despises Toshinori's "easy breezy little attitude", finding it to be annoying. Despite his antagonism to All Might, Enji does have a begrudging sense of respect for his skills and strength. However, upon learning of his true form, Enji was furious that his true form was so meek and small. His hatred of All Might only intensified after the latter retired as a Pro Hero and Enji would be given the No. 1 spot he always wanted but furiously refuses it due to the fact he didn't earn it nor does he feel he deserves it.
