The Shinobi Alliance has pushed Madara and Obito into a corner and they have the incomplete Juubi. Madara gets rapestomped with just Shukkaku and no Obito.
Madara is in possession of the one-tails? I must've missed that. When did it happen?
OT: Doesn't matter. He can take quite some fodders with him, but I don't see him take the Kyuubi, nor the Hachibi, so he gets beaten. Would be a hrad one to fights against a fully stabilized PS, though. I think a select team of specialists would be bettere then an entire army.
Are the five kages included? If so Madara loses with even less difficulty than I first thought.
Naruto alone is strong enough to hold his own against Madara without getting completely destroyed. The Shukaku is child's play for Killer Bee. Naruto's chakra gives big boosts to everyone in the Alliance which would allow them to compete with Madara even if he uses PS. Team work, kyubbi chakra and sheer numbers overwhelm it.
