Big Ball Rasengan

The Great Ball Rasengan is a technique created by Naruto Uzumaki during the gap in time dividing Part I and II. Like the regular Rasengan, Naruto uses the shadow clone to help form it into a condensed, self-sustaining ball of pure chakra. By adding increased amounts of chakra to it, he is able to increase the size of the regular Rasengan, in turn increasing its power. It deals astounding damage to the area and the target, but it takes a lot out of Naruto. Jiraiya himself even further upgraded the Great Ball Rasengan into the Super Great Ball Rasengan. Naruto, after mastering senjutsu, is able to use Sage Art: Great Ball Rasengan.
