Mr. Grave wrote: And that is the textbook definition of a headcanon. Manga clearly dictates that Obito was only out of control in the initial moments after obtaining the Juubi and in his final moment as Jinchuuriki when Naruto KO'd the shit out of him with talk no jutsu. All that happened in between was Obito in full control of the Juubi, getting jerked around and only occasionally gaining the upper hand. If he was in full control, then why could Naruto even affect him? Sure in his second phase he had greater control, but it was not full control, since he could not Kamui himself in any way. Yet madara, in full control and with a stolen eye, could.

Evidence points to the fact that he wasn't in full control.
