Naruto while in Nine-Tails Chakra Mode creates a Big Ball Rasengan in one of his hands, which is then surrounded by three regular-sized Rasengan, in a similar manner to moons around a planet. When coming into contact with a target, the disordered rotations of the individual Rasengan, created by the central and smaller ones spinning in different directions, interact with each other to form a massive and turbulent wave-like vortex. The strength of this technique is so great that it took even a shinobi reincarnated by the Impure World Reincarnation technique a significant amount of time to regenerate, which they normally do instantly.^[1]
