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.
- It was noted that if the Ultra-Big Ball Rasengan were to explode, it would easily carve away an entire mountain.
- Two clones of Naruto used this technique outside of Sage Mode, while the clone which created them was gathering natural energy.
