Skaði

Skaði is a technique utilized by Izumi Soga. It is the only technique granted by her Mangekyō Sharingan and is described as the ability to burn and reduce everything to ashes. It allows her to form a gigantic, dragon like creature made of flames.

Overview
It allows her to form an enormous creature with looks that follow the usual characteristics of a Dragon: having a massive body, a pair of wings that allow him to fly, four limbs with claws, and a tail. However, unlike most of the known Dragons, this one's body is not covered with scales, but it seems to be entirely made of flames, giving him an overall impression of a burning skeleton. The flames are so intense that they would incinerate and reduce anything to ash without even physical contact. This dragon itself represents Izumi in a battle, the dragon can produce a massive roar which not only blows away everything in it's radius but the roar also contains it's fire element, which is capable of melting rocks and setting an entire forest on fire within a short span of time. The dragon can also fly at high speeds, which allows it to attack it's target(s) at any given moment, additionally the user can ride upon the flaming dragon if she wants. The flaming body does not have an effect on the user. Due to his body being entirely covered in flames, any person who so much as touches this dragon will be burned down to ashes. In addition, this flaming body has a tendency to absorb fire based ninjutsu, which allows it to grow even stronger than before.
