蒼そう炎えん, Sōen?): Dabi's Quirk grants him the ability to generate and control highly destructive blue flames from his body. Originally orange and red, his Quirk turned blue after going through a growth sprout. He has very well-developed control of his flames and can project them far from himself and in large amounts. Furthermore, his flames possess greater firepower than his father, Endeavor's, Hellflame Quirk, and they become even stronger when Dabi feels strong emotions.
