During the two-year break with jiraiya, Naruto mastered the "second form" of the rasengan. the giant rasengan. It is twice as big, and even for naruto, required two shadow clones(doppelgangers). It is used in the FAKE ITACHI V.S KAKASHI AND NARUTO, and the KAKUZU V.S NARUTO battle along with the rasen-shuriken.
