Guts Rasengan


 * Name:
 * Type: Unknown rank, Offensive, Short Range (0-5m)
 * User: Naruto Uzumaki
 * Debut (Movie): Naruto Shippūden 2: Bonds

Remembering Jiraiya's words about never abandoning his nindo, Naruto creates a fully charged Rasengan but increases its mass and raw force. It has shown enough power to blast away an entire wall of a fortress and even decimate it in a matter of minutes. This technique can be compared with the Great Ball Rasengan having many similarities, except being much smaller.

Speculations
It was believed after the release of the movie's trailer that this was actually the Wind Release: Rasengan, due to its leaking rotating chakra and green color.
