Tailed beast mode

By mixing narutos chacra and kuramas two
By melding Kurama's unrestrained chakra together with his own while in Nine-Tails Chakra Mode, Naruto is able to enter Tailed Beast Mode (尾獣モード, Bijū Mōdo), with his shroud undergoing a drastic change. The shroud itself parts down the middle and opens into a full-length haori, revealing a black undergarment with magatama near his neck, whilst his seal's numerous swirl-patterns, which were located all over his body, open out into complete, dark, circles. Naruto also gains slit pupils, not unlike those of his first tailed beast transformations, and his whisker-markings become much thicker.
While in this form, his speed and strength are enhanced greatly to such an extent that he was able to deflect five Tailed Beast Balls by simply moving past them, as well as quickly move to two different locations on a battlefield at once by creating a shadow clone. He is also capable of using the Rasengan and the Super Mini-Tailed Beast Ball with a single hand in this form. Seemingly, the only flaw to this transformation is that the length of time it can be maintained is dependent upon the link between Naruto and Kurama, with Kurama noting that they could only keep the form for five minutes during their first transformation due to the fact that they had not yet developed a perfect bond. The amount of time they can consecutively maintain the form increases as the two continue to work together, extending the duration to eight minutes by the time of the Ten-Tails' revival. After gaining aditional experience with this form, Naruto could mix his own chakra with Kurama's and distribute it to his comrades, which manifests in then as a tailess "Version 1" chakra cloak and greatly empowers their abilities.

Tailed beast ball:</sup>
 he Tailed Beast Ball is the ultimate technique of a tailed beast. To form the attack, they gather both positive black chakra , and negative white chakra, 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 can be detonated for a wave explosion or launched to form a dome-shaped blast which flattens and erases everything around it, 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 created one, ground around him sunk beneath his weight after he swallowed it. When used in close proximity to other tailed beasts performing the technique, the Tailed Beast Balls can be combined, vastly increasing the attack's destructive power and size.
