It may sound stupid but I think tobi is somehow madara's splitting.
cOME'on guys if tobi was someone else then he could have gave his rinnengan to tobi.
Yeah , just like itachi used it and i would like to say that itachi also defeated edo nagato and sasuke 's abilities are same aas itachi with profit of EMs
U maybe a little bit rite but no1 knows what will happen because in the latest chapter, sasuke said he is no more a child and he was looking a little bit good .
