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 Style consists of mid to long-ranged offensive techniques that cause combustive and explosive damage. The art of having the flames obey the user's will is considered outrageously difficult. The chakra nature is common among shinobi of Konohagakure in the Land of Fire, notably within the Sarutobi Clan and Uchiha Clan, the latter having been noted to hold a natural affinity for it.
Amaterasu, a power only acquired through wielding the Mangekyo Sharingan, is stated to be the highest level Fire Style ninjutsu. This technique is composed of black flames, produced by a specialised form of Fire Style that Sasuke Uchiha refers to as Inferno Style, utilized by him and his brother, Itachi Uchiha. As shown by Sasuke, it is possible to add shape transformation to the black flames using Inferno Style: Flame Control, fashioning them into various weapons and defenses. Aside from using Amaterasu, Sasuke can create these flames with his Susanoo as well as in his own palm. Cee stated that Sasuke manipulates the flames with his right Mangekyo Sharingan whereas he casts Amaterasu with his left.
