Tailed Beast Ball

The Tailed Beast Ball is the ultimate technique of a tailed beast. To form the attack, they gather both, and , 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 ball can be fired differently, either in sphere form, which gives it a wide area of damage, or as a concentrated beam of energy which gives it explosive penetrative power. A Tailed Beast Ball is incredibly dense, as when Naruto Uzumaki in his four-tailed form, sunk the ground beneath his weight after he swallowed it. When used in close proximity to other tailed beasts, the Tailed Beast Ball can be combined, vastly increasing its destructive power and size.

The power of the attack is relative to the power of the user. The technique fired from a four-tailed Naruto broke through three Rashōmon gates without losing its momentum. A fully charged Tailed Beast Ball from Gyūki can fill an entire valley with the explosion as well as plough through a multiple layered barrier, while Kurama's own can create an explosion that is far larger than the Hokage Monument and the mountains around it, and equal that of a combined ball of five tailed beasts.

The tailed beasts' jinchūriki can use this ability, though they need to be in their full tailed beast forms. Should the jinchūriki lose control of their tailed beasts, they can perform this technique despite not being fully transformed, as seen when Naruto used it in his four and six-tailed forms.

Minato Namikaze based the Rasengan off of the Tailed Beast Ball. Killer B observes that the process for forming a Rasengan is exactly 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.

Trivia

 * According to Gyūki, using this technique feels very much like throwing up.
 * Shukaku uses Wind Release: Drilling Air Bullet, a technique of compressed air mixed with chakra from its gut instead of drawing together raw chakra, similar to the Tailed Beast Ball. However, Killer B implied that all tailed beasts can do the Tailed Beast Ball, and Shukaku simply wasn't out long enough to perform the attack when it fought against Naruto and Gamabunta.
 * In Naruto Shippūden: Ultimate Ninja Storm 2, Gyūki performs a lightning-element version of this technique.
 * In Naruto Shippūden: Ultimate Ninja Storm Generations, the character Masked Man's ultimate technique consists of summoning a controlled Nine-Tails, who launches a Tailed Beast Ball against the opponent.
 * In Naruto Shippūden: Ultimate Ninja 5, Naruto Shippūden: Ultimate Ninja Heroes 3, and other games, Naruto performs a version of this technique in Four Tails Mode called.
 * In Naruto Shippūden: Kizuna Drive, a beast known as the Three-Heads is shown using a technique similar to a Tailed Beast Ball. However, it isn't shown forming a chakra ball and only the beam is seen.
