Fire Release

Fire Release (火遁, Katon, English TV: Fire Style) is one of the basic elemental nature transformations. It is performed by moulding superheated chakra inside the stomach before releasing it via the lungs and mouth. There are also variants to this in the form of some mediums such as the use of gun powder, ash, explosive tags and chakra flow into a weapon.

Commonly affiliated with the Tiger hand seal, Fire Release consists of mid to long-ranged offensive techniques that cause combustive and explosive damage.[5] The art of having the flames obey the user's will is considered outrageously difficult.
