Scorch Release

is an advanced chakra nature kekkei genkai. This nature creates chakra that is capable of heating up an enemy to the point where all the liquid inside their body evaporates, killing the victim and leaving them a desiccated corpse. It is unknown what elements this nature entails.

Without the Kekkei Genkai
During the Fourth Shinobi World War, while trying to attack the Ten-Tails' main body, Sasuke Uchiha and Naruto Uzumaki combined their fire and wind-natured techniques at the same chakra ratio; resulting in a technique which was called "Scorch Release" by Minato Namikaze, despite neither user having the Scorch Release kekkei genkai.

Trivia
