Muu will come back via Rinnegan Power from Edo Madara and show the true power of Dust.
Then he will seal the Kyuubi in himself becoming the new Jinchuriki and
Steal one of Sasukes EMS Eyes, while learning how to make his body a loving indestructable Edo, then Steals Tobi's Rinnegan, while imPlanting all of Kabuto's DNA into himself and then finally implanting Hashirama DNA.
Afterwords will teach the world true peace theough being a living unbeatable Authority.
My prediction is that it will be naruto vs sasuke, and the reason will be that sasuke wants to destroy the kyuubi and the other tailed beasts, and naruto will try to defend them, i know tailed beasts respawn after some time but maybe by sealing or whatever, or could be that oro scroll has some info about that.
Naruto and Sasuke will always be close in ability, if they're not currently matched at the moment, Sasuke will soon catch up. We know little of his current powers, so saying he's inferior at the moment is pointless, as we don't know.
the way the story is progressing i highly doubt naruto and sasuke will fight. how could you determine who will come out on top. without disappointing the fans?
I think Sasuke will have a change of heart but Naruto will still request that they battle each other since he's felt inferior to him after all those years. Not necessarily trying to kill one another but giving it their all/no holding back...Test of strength I assume. :shrug:
what about itachi, sasuke wanted to talk to him about uchiha.......... and i wonder if itachi stop the edo tensei what will happen to him and i want itachi to change sasuke
