Kabuto cant beat nagato, he has to many summons, Almightly push, planetary devestation(which kabuto has know ansewer for),Universal pull then human path an take his soul when he touches him, Missles, Some weird cannon thing he was gonna shoot killer be with, Can absorb anything kabuto throws at him or can absorb his chakra from close range attacks too an ahole lot of other stuff that kabuto has no ansewer to. An nagato can fly, i know everyone says he cant, but he has all the paths powers so if the deva path can fly so can he.
Minato will beat sasuke because he's smarter an faster. Amatasrsu wont be fast enough an neither will the arrows. Knowing sasuke he'll try taijustu like he did with danzo an get a seal put on him an then its a wrap for him.
Kimmamro, he's cool an all...but he doesnt stand a chance against sage mode an that will be a quick fight.
10,000 zetsu clones seems kinda random cause the clones had nothing to do with kabuto an tobi already had that prepared. But those things are weak an wont really be a problem for anyone.
Madara will probably go after nagato since he's the strongest. But pretty much anything he trys to do will be counter because nagato is stronger with the rinnegun because he's had it longer an madara got it almost right before he died. His attacks with the sharingun an his base attacks will be nothing to nagato.
