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 .
Maybe tsunade helps kages but it wont change anything bcz madara has defeated them without even using his whole power and if the alliance also comes then madaras full susanoo is gonna destroy them
