Indeed, interesting... possible answers:
1) There was no other way to link Madara with an spare Uchiha to follow his plan.
2) He didn't need to. He brainwashed Obito, he didn't need more than that but...
3) ...we don't know anything about this, maybe Madara is still doing this.
? What the guy I was responding to was saying was that Madara has been controlling Obito the entire time even after his death, not figuratively, but litterally controlling Obito. The same way Obito was controlling Yagura and making him do things. So my questions were as follows:
1) If he was controlling Obito the entire time, then what is the point of the flashback where Obito agree's and has reason to willingly join Madara. If Obito did so willingly then their is no reason for Madara to implement this "Control".
2) We arent talking about brainwash, what the guy I was responding to said was litterally controlling Obito, as in, Obito isnt here right now, leave a message and he will get back to you when I am done controlling his body. So what I was asking was that How did Madara maintain this controll even after his death, which is when Genjutsu wears off.
3) We know Madara isnt based on the fact that they seem to argue with each other and disagree, not to mention Obito made himself the Jinc instead of reviving madara with Rinne Tensei, but perhaps this is all an elaborate ruse?
you should at least read his summary to get the jist of it all.
and seeing that the summary revolves around some seal that has never been spoken of, I can't make sense of the rest.
[fear] instead of "theory", I can only speculate as to why..
What seal are you talking about?
I used fear to differentiate my theories from other theories, the only thing I post are theories so putting theory there seemed redundant, fear seemed more suitable.
