The Great Dragon's Roar is one of the most powerful fire-based jutsu in the world. It was said to be developed by Madara Uchiha, and then passed down by the Uchiha bloodline. Aichi Uchiha managed to find the scroll containing the formula and then taught it to herself and Gen Nakaido. This jutsu has been known to destory entire forests and even evaporate lakes.

This jutsu requires excellent timing and chakra control to perform. First, after forming the hand signs, the user inhales deeply and builds up chakra in his or her diaphragm. Once the lungs and diaphragm are chakra-filled, the user releases the chakra in a loud yell that turns into a roaring-like sound and a emourmous blast of fire-infused chakra is released. The blast can be up to 95 meters in diameter and the internal temperature in the blast can reach over 6000 °C.

This jutsu is just as risky as it powerful, however. The amount needed for this technique is immense, and even Kage-leveled shinobi use this technique with caution. Another risk is the jutsu itself. One wrong move during release could result on the fire blast backfiring and burning the user. This usually results in death. In addition, the blast's damage radius is high, and damages everying in a high angle. Aichi was able to amend this by blowing her breath in a stream, resulting in a focused stream blast that is more powerful and easier to manipulate. It is also more compatible with Wind Release Techniques.

It is also said that more powerful versions of the Great Dragon's Roar are available. However, the only ninja who knows about these jutsu is Madara. No formulas for these jutsu have been written down.

Usage
Only five shinobi are known to have use this technique. Those ninja are Aichi Uchiha, Gen Nakaido, the 13th Zaokage, Elder Tsuchikun Nakaido, and Elder Rensuke Nakaido. Madara Uchiha, who is said to have invented the jutsu, may have used it once during his battle against Hashirama Senju. It is also that anyone who achieves the Mangekyo Sharingan automatically learns this technique, which could jump the number to nine.
