Ōdama Rasengan

The Ōdama Rasengan, was the fully charged variation of 's standard special move in Super Smash Flash 2 until v0.8a, when it was replaced with Fūton: Rasenshuriken.

A ninjutsu with pre-eminent destructive power, caused by wildly spinning chakra inside one's palm and compressing it to a high density — the Rasengan. Using the same essentials, but also rapidly increasing the amount of chakra used, results in the Big Ball Rasengan. It was created by Naruto Uzumaki during his training with Jiraiya. Like the original, Naruto uses a Shadow Clone to help form it but unlike the original technique, the shadow clone helps him to carry it. Compressed to an even higher density than before, the chakra is released all at once as soon as the technique hits the target, releasing an extraordinary destructive power. Proportional to this power, the amount of chakra it consumes is also extraordinary. With him possessing the near-inexhaustible supply of the Nine-Tails' chakra, it could be said that this technique is for no one but Naruto.

This technique is a much more powerful version of Naruto's standard Rasengan and can trap opponents inside before blowing them away with incredible knockback. Kyūbi Naruto's version of this attack is called the Kyūbi Rasengan and is even more powerful than the Ōdama Rasengan.
