Six Paths: Shinra Tenkyō

Naruto manifests his three-headed Tailed Beast Mode, and forms the Six Paths: Ultra-Big Ball Rasenshuriken; Sasuke, using the chakra of the Tailed Beasts to enhance his Complete Body — Susanoo, forms the Indra's Arrow. They fire off their techniques simultaneously at the target, resulting in a cataclysmic explosion.

Trivia

 * The explosion of this technique is identical to the clash of the same two techniques from Naruto and Sasuke's final battle in chapter #697.
