While in Nine-Tails Chakra Mode, Naruto gathers and balances the necessary black and white chakra to form a condensed, miniaturised Tailed Beast Ball. Upon impact, the ball explodes resulting in a very sizable blast radius. As with the Rasengan, he can extend the ball forward with the use of a chakra arm. Naruto can use a shadow clone to help him form the ball,[1] while in Tailed Beast Mode he can form it on his own.[2]
