Jet Burn

Jet Burn (ジェットバーン), full name Flashfire Fist: Jet Burn (赫灼熱拳 ジェットバーン) is an Ultimate Move performed by Endeavor and Dabi using the Hellflame and Blueflame Quirks, respectively.

Description
Endeavor concentrates his flames into a white-hot point on his fist and punches, sending a fiery beam into his target while knocking them back. He was able to use this attack to burn through Hood, but he quickly regenerated from the damage.

Dabi later used the move against his brother, Shoto Todoroki, during the Paranormal Liberation War. Unlike his father, Dabi only shoots his fire rather than punching towards his opponent. However, during the second War, Dabi uses it again against Shoto, this time in a punching form, similar to his father.

Endeavor states that this move is usually reserved for finishing battles as rampant use will raise his body heat too high.
