Obito has Rinnegan so him being able to control the Juubi should not be hard. I had this discussion with a couple of my boys. We basically all came to the conclusion that since he already has control of them, gaining BM should not be a problem. He basically locked the 7 tailed beasts inside of the Gedo under his control anyway! My question that I'm asking is; in 638 or 639, do you think there will be an Obito in BM?
