Fire Release: Fire Dragon Flame Bullet

The user kneads their chakra into flames, which are then manipulated into a genuine-looking dragon. Since the art of having the flames obey the user's will is outrageously difficult, its mastery is restricted to a limited number of skillful shinobi. The flames are divided to launch a left side, right side, and frontal assault in all three directions at once, turning the enemy into ash in a matter of seconds.

Trivia

 * When used by Hiruzen in the anime, he merely spews out a single stream of fire which seemingly had no definitive shape.
