Since its first appearance Dabi could attract attention. The character had a ruthless appearance, which was manifested from the very first attack on the summer training camp. Over time, Dabi has carved out more and more space in My Hero Academia, becoming a key member of Tomura Shigaraki's League of Villain.
With the war between heroes and villains, Dabi's origins as well as his true identity were explained. The readers of the My Hero Academia manga thus learned that Touya Todoroki was still alive and that the particular conditions of his Quirk did not guarantee great physical durability. Because Dabi has scars? Precisely because of these badly mixed elements.
Dabi was born with a fragile body like his mother's, but with an even stronger fiery quirk than his father's. Due to his obsession to become a hero and fulfill his parents' ambitions, Touya pushed himself to the limit to create blue flames. However, these flames are too strong and the body suffers: Even as an adult, after the manipulations of Dr. garaki, Dabi is badly affected by the flames.
As seen in some battles, the more times he uses the blue flames, the more his skin burns. Burns result from this use of the Quirk. Daby has scars from her flames and he will carry that around with him until he dies or until he has left My Hero Academia.
