Tailed Beast Rasengan

To get around the fact he couldn't use either the Tailed Beast Ball or Shadow Clone Technique while using the Nine-Tails' chakra, Killer Bee advised Naruto Uzumaki 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.

According to Killer Bee, to complete the ability one needs to combined Light and Dark chakra to a ration of 8:2.

This technique is not to be confused with the Demon Fox Rasengan.
