Fire Release: Roar of the Fire Dragon

The user channels massive amounts of Fire chakra throughout the body entirely. Once this is done the user will bring the chakra up through the throat, and breathe a long line of super heated fire that moves at a rapid rate and becomes a large fireball that burns his opponent. This large fire blast has enough power to destroy everything in it's path.

Trivia
This jutsu is a Naruto adaptation of the fairy tail fire dragon slayer magic.
