Tailed Beast Ball

The is the ultimate attack of a tailed beast. To form the attack, the user gathers both positive "black" chakra, and negative "white" chakra, shapes it into a sphere, and then compresses it inside their mouth. The chakra needs to be balanced or it will backfire. The black and white chakra needs to be kept at an 8:2 ratio respectively. The power of the attack is also relative to the power of the user. The tailed beasts' jinchūriki can use this ability, though they need to be in their full tailed beast forms.

Minato Namikaze based the Rasengan off of the Tailed Beast Ball. Killer Bee observes that the process for forming a Rasengan is the same as forming a Tailed Beast Ball. However, the addition of chakra rotation is necessary to control the Ball without being in tailed beast form.
