Dabi

Toya Todoroki is a major antagonist in the My Hero Academia manga and anime series. He is the eldest son of Pro Hero Endeavor, driven insane due to his neglectful actions, faking his death and becoming a villain as revenge. He became affiliated with the League of Villains, a former member of the organization's since disbanded Vanguard Action Squad, and later one of the nine lieutenants of the Paranormal Liberation Front. Alongside his teammates, he serves as one the main antagonists in the Forest Training Camp Arc, Pro Hero Arc, and Paranormal Liberation War Arc. Having been trained by his father, Endeavor, at a young age, and undergoing rigorous self-training, Dabi has proven to be a powerful villain, being one of the strongest members of the League of Villains' Vanguard Action Squad, as well as its de facto leader. After joining the League, Dabi has killed over thirty people, garnering a reputation as a dangerous criminal and a mass murderer.

Dabi has an effective handle on his powerful, yet hazardous Quirk, which not only grants him control over his self-generated blue flames that are stronger than normal flames, due to hating his father, but also proficient wide-range capabilities. Dabi primarily fights from a distance, shooting fireballs, generating flamethrower attacks, and releasing bursts of fire when at close range. His basic offense is using the brute force of his Quirk to overwhelm his enemies. Defensively, Dabi can burn away attacks and even generate massive walls of fire to surround his targets. With this skill and power, he can incinerate an entire group of opponents in mere seconds. Overall, Dabi has the capacity and ingenuity to contend with a multitude of adversaries who outnumber him. The immense capabilities of Dabi's Quirk allowed him to repel the Bakugo Escort squad during the Vanguard Action Squad Invasion, fight off multiple Meta Liberation Army members and emerge unscathed, as well as extensively fight on par with Geten, one of the MLA's strongest members. He even completely overpowered Hawks, the No. 2 Hero, primarily due to pyrokinetics being major weakness to Hawks' Fierce Wings. These feats are proven to be even more impressive as Dabi never relied on his Flashfire techniques in any of these encounters. Dabi's Quirk finesse also enables him to fly and hover in the air much like his father and youngest brother. In the Paranormal Liberation War, Dabi began utilizing his father's Flashfire Fist techniques in combat and was not only able to instantly burn through Best Jeanist's Carbon Fibers, but effortlessly dominated Shoto (also using Flashfire Fist) in a battle of flames. The disparity in their abilities was so great, Dabi could hold back and defeat Shoto with a single Jet Burn, without killing him. Dabi's Quirk grants him the ability to generate highly destructive blue flames from his body. He has very well-developed control of his flames and can project them a fair distance from himself and in large amounts. Furthermore, his flames possess greater firepower than that of his father, Endeavor's, Hellflame Quirk, and they become even stronger when Dabi feels strong emotions. However, Dabi's body has a low tolerance for his own flames, due to inheriting his mother's resistance to freezing temperatures, rather than his father's resistance to high heat, and he will get burned if he uses them for prolonged periods of time.
