Re: How I would have handled the reveal of Tobi's Identity and Plot
Seems like a good plan, although i personally would just stick with Tobi being Obito, but just in a different way. The Izuna/Kagai stuff would have worked, but would've had less significance at this point, especially with Kakashi on the front lines.
The main problem with the reveal is that it was far too obvious from the beginning. From the very start, when Deidara's arm showed up next to him after Kakashi's kamui, or when he fought Konoha 11 and showed off the ST ninjutsu, his identity was exposed. I would have gone for less identity exposure throughout the story, which results in a greater plot twist during the reveal with a greater impact.
I ended up feeling fairly disappointed when the chapter came out, and now Obito's attitudes and ideals are screaming for a TNJ from Naruto to make him change his ways. Remember when Shikaku said "he's nothing like Nagato"? I thought "yes, finally, a badass who isn't manipulated by anyone, who controls everything from the shadows and is completely unaffected by TNJ" Now with the "you let rin die" and pessimistic dialogue all the time you can tell he's gotten soft ever since he took off the mask. This is why I only have faith in Orochimaru as the true villain of the series now.
For those who will probably tell us to "deal with it", here's my response. Up until the reveal, the general thought process of most people was something like this. In chronological order:
1. "Yep, Tobi is Obito"
2. "Hmm, hold on. Kishi's cleverer than that, surely a massive twist is coming up. Tobi=Obito is far too obvious"
3. "Let's think of other possible theories that could work"
4. "Oh. It is Obito. Guess there's no plot twist after all. Cheers Kishi"
People who littered NB with "I told you so" threads a while back have simply achieved the same as those who originally though Tobi was Obito in the first place, they have gathered the simple evidence that Kishi left for all of us and made a thread about it. In fact, I can say with confidence that not a single Kagami/Izuna thread was made by someone without that person originally thinking that Tobi was Obito, only to then change their minds because they had faith in Kishi to come up with a more intelligent plot twist.
The thing I disagree with the most are the claims that "Kishi is a genius" for managing to keep the fans sidetracked and effectively double bluffing us into thinking that Tobi wasn't Obito. In my opinion this is not the case, I believe it is simply bad writing. Double bluffing doesn't really work in the story, because fans simply go back to their original ideas when they first saw Obito, and are then even more disappointed because nothing surprises them when it comes to the big reveal.
tl;dr version - Keep Tobi as Obito, but Kishi shouldn't have left so much simple evidence throughout the story that it makes the reveal boring. Lol. Rant over.
