Alright! I have a theory about Chapter 629. I know most people think the Juubi got angry because Naruto resembled Rikudou... but I think different. I think that was Rikudou getting angry from seeing Naruto. And I also think the final form of the Juubi will be Rikudou. I mean that's the only way I see him being introduced right now. Because Obito and Madara wouldn't want to bring him back with Edo Tensei due to his emense power, and he'd just take control of the whole operation. Plus they don't even know how to do it. The only person that can is Orochimari and he's with the good guys now. I mean how else would Kishimoto introduce Rikudou at this point? But this is just a theory, comment and tell me what y'all think.
