ok maybe im wrong but how the hell is anybody going to fight any of the deceasd ninja? If I remember correctly you need to seperate the soul from the body inorder to have the jutsu deactivated (this is why the third needed to use the reaper death seal) because nothing he was trying was working. Im assuming that not many ninja have high level seals to do this.
On top of that Zetsu can assume the form of ANY body he has come into contct with... meaning kisme(if I spelled that correctly) or even the ninja's he is currently fighting or any ninja he had come in contact with.
Then you must concider both Mandura and Kabuto (both a badass on his own) and then Kabuto's secret summon AND Mandura's tailed beast/he can revive any fallen warrorsO.O
My question is how is the alliance going to win?
The only possible people to even remotly stnd up to all this is the captians, hokages, and B/Naruto and even they cant defeat everything at once.
more then likely the battle will end up like this
