Nine-Tailed Fox Menacing Ball

The Nine-Tails gathers a mass of raw chakra and molds it into a sphere. The sphere is then consumed and the explosion is as a concentrated ball of chakra. Naruto, when the Nine-Tails has control over his body was also able to fire the Menacing Ball. From fourth tail, the chakra was consumed normally and fired, and the sixth-tailed form simply fired the attack right away. The blast is strong enough to destroy three Rashōmon gates without losing any of its momentum and devestate the already destroyed village of Konoha during Pain's Invasion.
