This is a toughy,
Animal paths summonings are all beaten by manda 2
I don't believe white shock will work on the paths , since they are dead bodies..
Muki tensei, would be able to kill like 3 paths instantly.. .you can't see when it's coming , spikes just appear out the earth and stab you, thus it got itachi..
Kimmiamaro's sawabi no ma, might be able to kill 1 or 2...
Chibaku tensei is a decider in this fight.. , I dont know if he can use muki tensei to control it and make it suck nagato in instead... Sounds farfetched, but it is supposed to be able to control any non living thing...
urm If kabuto gets tayuya's genjutsu off, I see all the paths as being screwed heavily..
All of them would be affected, There won't be any one not affected, that can get the other out..
I don't know how nagato is countering that,
A theory of mine is that he can cut the chakra to the path bodies, then add more, might be able to get him out
Or maybe disrupt their chakra flow
I don't know.. If he could have done that through control, he would have gotten his paths out of jiraya's genjutsu.. That makes me question if he can...
Shinra tensei is another op jutsu of deva path... I don't think out of kabuto's arsenal he has a counter for it.. His only hope is getting kabuto with the flute genjutsu or something before he uses this.. Though when it was used, many konoha ninjas survived with Some healing from tsunade...
Kabuto does have snake skin regen and uzumaki regeneration capabilities.. so i have no doubt he would be able to survive it.. but then again he would be getting a direct hit..and even then shinra tensei's real damage only lies if you slam into something from the force, or something slams into you... Considering kabuto can control nonliving things, i don't see how he'll get seriously hurt from this
I'll say Kabuto , 6 times out of 10
