Obito and Madara have no chance.
The Juubi is strong... Very strong. Madara and Obito are both very strong also. But seriously, come on now.
Naruto BM mode, Kakashi, Gai, Bee, Konoha 9, Shinobi Alliance, AND the 4 previous Kages?!
I think I'm sold on Edo Madara > Edo Hashirama. But that's just because Edo Madara is basically a Gogeta of the 2 right now.
But for real though, all those people I listed, plus Naruto setting up the Kyuubi Chakra concession stand... Obito, Madara, and the Juubi stand no chance.
