kabuto, naruto, minato, danzo, sasuke. or in the event we arent allowed to max out, jsust kabuto.
Even with all those edo's its not enough, most of the edo's are nobodies to madara nagato and tobi,
its a waste of chakra to try and soul remove all of them. they will come at the group all at once. plus you have several kekkei genkai, treasured tools, swords that cut anything, kages, and akatsuki. the only nobodies were rezzed to mindfuk the opponents like sai's brother and haku.
even they wont stand a chance, and the rest simply dont have what it takes except the 1st and if itachi gets off a lucky toksuka blade, although i do think he could be tobi 1 on 1.
no one can take tobi 1 vs 1. and why wouldnt they stand a chance? immortality isnt easy to come by and tobis got no sealing jutsu except his flame barrier. madara has no sealing jutsu. nagato has soul removal but how many can he really soul rip before being overwhelmed? if nagatos an edo he will be careless and take hits thinking he can tank it when in reality he's been touched by rikudos rope and gets sealed.
Izanagi? he couldnt even beat sasuke with that dont make me laugh
he effectively did, til karin saved sasukes ass and when sasuke got a random plot powerup to break the curse seal
He can not hold back all he wants nagato,madara and tobi would all rape him
can they? while having 4 other god tiers to worry about?
And i doubt madara would lose to KA as he mastered sharingan far beyond any other Uchiha
KA is designed so the opponent cannot notice. itachi intended to trap sasuke in it whos second among all uc
