Blueflame (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. 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.

Decay (崩ほう壊かい Hōkai?): Tomura's original Quirk allows him to disintegrate whatever he touches with all five fingers. It will take effect whether the target is organic or not. The disintegration spreads quickly and will spread through the victim's whole body if they don't amputate the decaying body part. His Quirk can even spread beyond what he's touching, allowing him to disintegrate large groups of enemies instantly.

Because the Quirk has to touch a solid object in order to be activated.
