i appreciate all the comments on my theory but i couldnt help but notice that most of the ones who wouldnt even consider it are uchiha fans.. i understand how yall feel about the clan lookn at madara and what each of their sharingan's can do, the possibilities of their power are outstanding, but dont forget the IS just an anime, an in the naruto universe no matter how strong the clan is, until the name of the show changes to the Uchiha Clan Adventures, making them stronger then the lead charater in the show will never happened..
sorry if that sounds like fan-boyism too yall cus once again my fav is the toad sage (big J) and kissime. but as everybody who took a guess on who tobi was can tell yall, as long as kishi's telling this story it'll never turn out how you think ... just a thought
