Naruto's ultimate attack. Created as an alternative to Rasenshuriken, this Rasengan is two Rasengan combined. Naruto first creates Wind Release: Cyclone Rasengan in one hand and Water Release: Tsunami Rasengan in the other. He then combines to two creating a Rasengan with two elemental chakras in it. It is the size of the Great Ball Rasengan with wind blades and water jets swirling around the Rasengan on the outside. Unlike the Great Ball Rasengan, this can be wielded with one hand. When it hits the target, it traps the target in a vortex of condensed wind and water chakra. Extremely useful on enemies who have Fire or Ligtning element chakra. No one has survived from the Tempest Rasengan.
