Almost every MHA fan knows the fan theory of Dabi is Todoroki TÅya, itās so well known that itās got to be the most famous fan theory in MHA. Due to the the popularity of this theory, I wonāt go into the detail of how and why Dabi is Todoroki TÅya, but how he got his scars.
Today, as I was watching older episodes, I realized something I hadnāt noticed before, the location of Dabiās scars. As we the viewer knows, Dabi has five visible scars. One on each eye, and arms, and a large one on his jaw/neck. On closer inspection, you realize that the scars (no doubt burn scars) are located on places where Endeavor has his flames. For asthetics, Endeavor keeps his flames on his face and his arms. My theory is that young Todoroki TÅya wanted to impress his father, or maybe he wanted to be like him, so he tried to copy Endeavor. We know from the manga that TÅyaās firepower is greater than Endeavorās, but he inherited his motherās weak constitution, which is why Endeavor deemed him a failure. What could have happened is that, TÅya attempted to use his flames to look like his father, but since his flames are hotter, and heās weak, he burned himself. Itās also, possible that itās after this incident that Endeavor realized TÅya is a failure, and Dabi ran away because of this.
Again this is only a fan theory, and Iām possibly wrong, but the location of Dabiās burns canāt be a mere coincidence.
