Tailed Beast Rasengan

To get around the fact he couldn't use either the Tailed Beast Ball or Shadow Clone Technique while in Nine-Tails Chakra Mode, Killer Bee advised Naruto to use his chakra arms to attempt to create a Rasengan. The results were incomplete, though they looked like a combined version of the Rasengan and Tailed Beast Ball.

Naruto is having difficulty making the ratio of Black and White chakra 8:2, and the sheer weight of the chakra is burning his hands. He's relying on Killer Bee to tell him when he gets the proper ratio down since so far, its 9.5:0.5.
