Big Ball Rasengan

The Big Ball Spiraling Sphere (Oodama Rasengan in romanized Japanese) is a technique created by Naruto while training in the time skip with Jiraiya, prior to the release of the Shippuuden episodes. Although this technique requires Naruto to use a Shadow Clone, the result is a larger ball of condensed chakra. Much detail about the Big Ball Spiraling Sphere is unknown, but Leaf Ninja labels it a "potential S-rank." Range is unknown, but this technique is used for attacking.
