the buddah has 10,000 hands and yes, it would be a god fight. We know who would win but the juubi would need a lot more then just one bijuu dama to kill it. Funny thing is that the buddah senjustu tech is bigger than the incomplete juubi
I'd love to see it but I think the Juubi would win that..but I think if Hashirama does join the battle, they could use his amazing abilities to restrain the Juubi until they can get an awesome strategy in place
