Since no edo madara,alive madara would probably loose.
SO6P obviously
tobi 7 bijuus and gedo
sm kabuto edo tensei
and that's it,those three could take down anyone
nagato can't solo the kages,jinton is perfect for CT,and he can do it in the beginning stages,gaara and onoki can dly and attack from all directions with rock and sand techs,sand has no chakra,so that will put nagato on hold,tsunade and the raikage will take him CQC,Gaara would use his sand arms to save them if they get in trouble of being soul ripped and they can take ST,giant rock golem beats summons and jinton or giant sand burial finishes cerberus,sand sensing finds chameleon easily,sand burial to kill or sand coffin to distract him,then tsunade's punch finishes it as both of those have no ninjutsu chakra. Nagato is nothing to play abt,this will be high diff because of the many powers rinnegan gives.
Hashirama can't at all,wood is countered easily by sand and dust,hashi cant heal from gaara onoki jinton,they can both fly out of wood attack range,sand sensing keeps track of any wood clones around,gaara and onoki finish it with super jinton. The guy is all hype.
Sm kabuto without edos wont,raikage's lightening is bad for him,A can keep up with him as well,he can take white rage as his body is very endurable,he can react to bone forest or just cut them up,webs arent doing anything to him,he sliced a horn of hachibi and the force knocked it to the ground,so he can handle manda2,with a flying gaara as a partner this will be high diff due to their skills set,sound gen can be done like shika,as gaara's sand control is similar.
Hiruzen?not likely as we havent seen anything from prime hiruzen and old definately cant
Itachi? LOL,gaara or onoki solos high diff,gaara and onoki together win low diff,itachi vs 5 kages at once,solid rape,edo itachi would still loose
sasuke?,dont make me laugh,gaara onoki solos low-mid diffU_U
am i missing out anyone?
