Nine-Tailed Fox Menacing Ball

The Nine-Tails excretes chakra from its body and gathers it into a sphere in front of its mouth. It then consumes the sphere. The sphere detonates once eaten and the chakra is fired from the mouth as a powerful beam. This beam is at least strong enough to destroy three Rashōmon gates without losing any of its momentum. Consumption has been shown to not be necessary to use the sphere as an attack, as it can be shot like a normal projectile. Its area of effect is much larger when used as such.

The Nine-Tails' menacing ball has only been seen in full use when Naruto attains a chakra shroud. When the Nine-Tails itself has used it has always been neutralized before its full impact can be seen. It is suggested to be capable of much stronger forms of the technique than Naruto is, creating a sphere several times large than itself.

In the anime, a transformed Naruto is seen firing a more concentrated beam of chakra as well as lobbing several spheres at once.
