Tailed Beast Ball (Sigma)

The Tailed Beast Ball is the ultimate attack of a tailed beast. To form the attack, they gather both positive black chakra (+の黒チャクラ, purasu no kuro chakura), and negative white chakra (−の白チャクラ, mainasu no shiro chakura), shape it into a sphere, and then compress it inside their mouth. The black and white chakra needs to be balanced at an 8:2 ratio respectively or it will backfire. 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.

Should the jinchūriki lose control to their tailed beasts, they can perform this technique despite not being fully transformed, as seen when Naruto in his four and six-tailed forms. Even without a full transformation, the technique is capable of destroying three Rashōmon gates without losing any of its momentum. A fully charged Tailed Beast Ball can create an explosion that is larger than the Hokage Monument and the mountains around it, as seen during the Nine-Tails' attack on Konoha.
