Six Paths: Ultra-Big Ball Rasenshuriken

While in his Six Paths Sage Mode, and fully transformed into Kurama, Naruto creates two shadow clones of the entire chakra construct. The shadow clones merge into the original, creating a three-faced, six-armed construct. In its right arms, it creates a Wind Release: Ultra-Big Ball Rasenshuriken, and its left arms, it creates a Tailed Beast Ball Rasenshuriken, both infused with natural energy. It is strong enough to counter Sasuke's strongest offensive technique.

Trivia

 * While unnamed in the manga, this technique was named in Naruto Shippūden: Ultimate Ninja Storm 4.
