Wind Release: Ultra-Big Ball Rasenshuriken

Naruto can greatly expand the size of his Wind Release: Rasenshuriken in his Nine-Tailed Chakra Mode thanks to his additional chakra arms. It is roughly the same size as Jiraiya's Ultra Big Ball Rasengan and its power increases dramatically enough to break through a giant barrier.

Naruto later combined this technique with Sasuke's Blaze Release: Kagutsuchi to create a swirling mass of black flames.

Trivia

 * On the Studio Pierrot website for episode 305, the "Wind Release" part of the name is dropped.
