Tobi's story is probably interesting. I have faith in where Kishi is going at the moment. I also think Tobi is someone that we have already met/already mentioned in the manga
^ It was right?!?! And seeing as how he's a Rubber man those specialized training dolls are more than likely a toll of his design. Epic old guy is epic.
*Gets on Soap Box*
I remember how when the war started people were complaining and frustrated at the way it started off, with Kankuro and his Ambush team etc, but looking back on it now, and re-reading practically 50+ chapters since it started (yes.. Its been THAT long ago), I must say Kishi did/is doing us epic justice with this NINJA WAR!!! Everything has been played off with such precision that it was hard for us to notice in a chapter by chapter basis, so I would recommend that people re-read from the beginning of the War (if you have time) to recap and soak in all the Modern Ninja Warfare goodness!!
*Steps down from his Soap Box*
Now I am not one to speculate, especially when it comes to secret Identities, but re-reading over the war from the beginning and trying to pick up on certain interactions its become obviously clear, as we have all realized, that the only person that might have Tobi's identity fully pinned down is Uchiha MADARA, with a hint of Kabuto (since he's a sly one who seems to be one step ahead of everyone). He obviously knows the person so intimately that he even knows that the Moon Eye Plan is the mystery person's final objective. How else would Madara know something like that unless he's deliberated it with the main perpetrator while he was alive? If Kishi makes Tobi someone we've already heard of then it HAS to be Madara's brother in my mind, chronologically it makes logical sense. If its someone new then anything is possible at that point. The whole Obito shit is overplayed and to me wholes no validity since Madara has acknowledged the plan's existence and mastermind. Although Kishi said Madara's bro "died" in battle after loosing his eyes (and I think I already made it clear how stupid I think it would be for an Uchiha to fight again shortly after losing his eyes) I am more willing to accept Izuna?* is still in some form of quasi-life/limbo state than anything else, which in tern could be the cause of his freakishly powerful multidimensional, teleportation, intangibility ability as well.
I will sure as hell re-read this arc, but only when I have more time (or when the manga ends :P).
And as for Izuna, you might be right. It would at least make some sense... but who knows what other asspu...(xD) surprises Kishi might have in store for us :D
Yeah, I intend on re-reading the War too, after I beat Zelda. It's an especially great time to do it now that the final battles are here and the War is closing in on its conclusion.
