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, noting it to be much heavier than the usual Rasengan. Despite the fact he has a chakra shroud while practicing the technique, Naruto's hands are shown to be injured as he practices. He's relying on Killer Bee to tell him when he gets the proper ratio down since so far, its 9.5:0.5.

Naruto has also noted that this new Rasengan is so heavy, he can barely hold it up.
