We know he died and only had 1 eye.
Kabuto found his body and did a bunch of stuff. So he was revived edo tensei younger.
now when he was brought back to life. both his rinnengan dissapeared. wouldn't it be logical for him just to have 1 eye?
or is it Kabuto's fault?
From what we know when Minato split Kurama he shrunk. Does Naruto's kurama mode show the real size of him or the smaller one? because he always seems bigger when we see him talking to naruto in his mind.

another link providing proof...
Sakura was talking about Tsunade almost done with his arm from hashi's cells. We see him talking to naruto which still has part of his arm missing too. time skip later, naruto got his implanted. did the same thing happen to sasuke when he came back to the village? obviously he came back at some...
I just thought of this. Can anyone take on the full kyuubi without any dojutsu?
We know the 3rd Raikage was a good match for the 8 tails. but thats about it.
Since Obito's ms power is to travel between dimensions, and with both he was even able to travel through Kaguya's dimensions. Possible he used it to travel between the dimension of the dead and into the "dimension" of Kakashi's mind and activate it for him through there.
just a thought...
