His hero costume is comprised of a flame domino mask, with a flame mustache and a long beard. Most of his body is covered in flames.

Personality
Endeavor 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. but since he isn't able to do it himself, he is even willing to do what ever it takes to surpass him, as he devises a plan to "create" someone who can surpass him. Endeavor appears to care little for his son, as he sees him as only a "tool" to further his own desires.

Past
Endeavor had a forced marriage with Shouto's mother in attempt to conceive and raise a child with a powerful Quirk in order to surpass All Might as a hero. Ten years before the start of the series, Endeavor once had a chat with All Might.

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 Yuuei Academy.

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

He watches furiously from the bleachers as Shouto declares that he will never use his Fire powers in combat. Endeavor continues watching Shouto and his team battling Izuku's team, commenting that Izuku has figured out Shouto'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 Endeavor for advise on how-to raise the next generation. Endeavor dismisses his request and then comments on All Might's attitude, finding it to be annoying. Endeavor states to All Might that he will make Shouto a hero that surpasses All Might and even though he is going through his rebellious phase, Endeavor states that he will definitely make it happen, then angrily walks away.

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

Shouto Todoroki
Endeavor is the father of Shouto. However, their relationship seems to be on unpleasant terms, as seen when Shouto complained that Yuuei 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 Endeavor watched from the bleachers. Endeavor only sees Shouto as a "tool" whose purpose is to surpass All Might.

All Might
Ten years before the start of the series, All Might once had a talk with Endeavor and since then, they have not spoken to each other. It appears that Endeavor has a intense rivalry with All Might (one sided on Endeavor's side as All Might tries to be friendly with him). This rivalry with All Might is so great that he decided to have a child that would be able to surpass All Might. Endeavor despises All Might's "easy breezy little attitude", finding it to be annoying.
