Fire Release

The area of elemental Nature Transformation  are offensive type techniques that allow the user to to manipulate their fire chakra-nature to create fire by super heating their chakra and releasing it from their mouths. Fire Ninjutsu is common among Konohagakure ninja, with the Uchiha Clan being particularly proficient with its use. Fire Release ninjutsu is commonly affiliated with the Tiger hand seal, "Tora".

A Fire Ninjutsu is strong against a Wind Ninjutsu, but will naturally be overcome by a Water Ninjutsu with the same level/rank. A sufficiently powerful fire-based attack can still overpower a water jutsu, causing it to evaporate.

As demonstrated by the fight between Hiruzen Sarutobi and Orochimaru in the Invasion of Konoha arc, Earth Release has a good affinity with Fire Release and so can be used together in collaboration jutsu. When used together, the Earth ninjutsu (Earth Release: Earth Dragon Bullet) needs to be implemented with the right timing in order to be combined with the Fire ninjutsu (Fire Release: Fire Dragon Missile), the Earth chakra adding more accelerant to the fire ninjutsu, giving it more combustive physical force.

Furthermore, in the case of Elementally-recomposed Nature Transformations, rarely found outside of a kekkei genkai, Earth-natured chakra can be blended with Fire-natured chakra; the molecular structure of the earth (that the earth chakra provides and controls) is superheated and induced to melt into molten liquid rock by the fire chakra, creating Lava Release Ninjutsu.
