Looking back in some old chaps i came across the sage toad prediction regarding naruto.
We all remember when he saids he would fight a young man with powerful eyes?
The majority of us instantly assumed it,was sasuke or tobi
But now i think its safe to assume its edo madara since hes young in his edo state and he basically has the strongest current eyes (ems,and rinnegan)
The next page he saids and you know what he is?
I think he said what instead of who because edo madara is basically a walking corpse and not really human.
So yeah this may be non relevant now but i think we can all agree the sage toad was referring to edo madara and not sasuke or obito or anyone else.
