clone? doubtable...
Yondaime becaaaause.
1. Itachi referred to Naruto as "Yondaime's legacy" (or something like that)
2. Jiyraiya admitted that Naruto was alot llike Yondaime.
3. In the manga... kinda subtle like, but Kakashi (to me) seemed to imply it.
there were alot more, but I'm too lazy to find them... Heck, I didn't even double check some of these... XD
Yondaime and Tsunade? good grief... how old was Tsunade at that time? alot older than Yondaime if I'm not mistaken...
I'll admit, the Akatsuki leader would be one heck of a twist...
