Ultra-Big Ball Rasengan

This technique adds natural energy to the Big Ball Rasengan. The natural energy rapidly increases it to gigantic proportions, larger than the user's own body, and is created in an instant. When it impacts, there is a large shock wave unleashed that can send unsuspecting shinobi flying.

The destructive power of this technique is such that were it to explode, it would easily carve away an entire mountain.

Trivia

 * Two clones of Naruto used this technique outside of Sage Mode, while the clone which created them was gathering natural energy.
