Big Ball Rasengan

The Great Ball Rasengan is a technique created by Naruto Uzumaki during the gap in time dividing Part I and II of the series. Like the regular Rasengan, Naruto uses the shadow clone to help form it. However, by adding increased amounts of chakra to it, he is able to increase the size of the regular Rasengan, in turn increasing its power vastly. It deals astounding damage to the area and the target, but it takes a lot more out of Naruto leaving him tired and breathless. 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.
