The miniature Juubi
Just in case you did not read it, I have already predicted that we would see a miniature Juubi (just did not think it would be so soon
Here is a thread about the miniature Juubi.
NB users, do you think:
1) that the Juubi will be small
In my theory, you need a fixed proportion of each Bijuu's chakra to create Juubi chakra. Tobi only has a bit of the Hachibi and Kyuubi chakra. That's why I think the Juubi will be a miniature.
2) that Naruto will get another Juubi
In my theory, Naruto will merge the bits of chakra he has received from all the Bijuu's (btw, isn't he missing one still? to create his own miniature Juubi.
