| This article is about Jiraiya's version. For Naruto Uzumaki's version of the technique, see Sage Art: 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.
Trivia
- If the Ultra-Big Ball Rasengan exploded, it would easily hollow out an entire mountain.[1]
- Two clones of Naruto used this technique outside of Sage Mode, while the clone which created them was gathering natural energy.[2][3]
