but i have to say that this theory is the worst i've ever heard. the 4TH HOKAGE, sealed the 9-tailed fox into a newborn baby, thats what happened. so that right there says he didnt seal it inside himself.
and saying that the kyuubi's healing powers turned the 4th into a baby.....thats not even possible. healing powers HEAL you, not somehow turn back time and turn you into a baby. AND so far all healing powers shown, have made your life SHORTER, not longer.
one last thing, just because other people make stupid theories, does not mean u have to add to the stupidity
Obito's got the sharingan, probably is Tobi, dought he's madara, cause' madara has long hair, maybe he got a hair cut, lol
