Juubi>Hashirama and Madara, thus Juubito>Hashirama and Madara as Juubito is Juubi +Obito.
There's been no proof he can go BM.
BM requires you to have a perfect link with the bijuu so I can't see that happening.
In the other Bijuu's case.
Its most likely that Jins of the Juubi can access its full power without needing to bond with it.
-Obito and Madara were able to access the full power the Juubi (Its full power at the time) by connecting themselves to its body.
-Immediately after becoming its Jin, he can utilize chakra arms. (If he's even in control right now) Naruto and B had to play chakra tug of war with their Bijuu in order to be able to do such things.
lol i would have proved you wrong but this is alive madara so igeuss not
anyways juubito wins
Edo Madara gets shit stomped by Juubito.
