Why is everyone trying to make Izuna or some other random douche we never saw before into Tobi. What's wrong with Obito being Tobi seriously, all you Naruto "fans" are crying and throwing tantrums saying you quit Naruto and spoiling the surprise for people who haven't read the manga yet. You talk about plot holes but there are none. It makes sense to me, I figured it out last year and it should be no surprise if you add everything together. Give me one reason why Obito can't be Tobi. Did they ever find his body? No. Are they missing the same eye? Yes. Does he have the same set of eyes as Kakashi? Yes. Why can't he be Madara? Because Madara is ****ing fighting the kages right now. How come Tobi appear so wrinkly and old when fighting Minato? Because his face was crushed under a rock 100x his size ffs. How he got out? Well think about the move he currently has that lets him warp to another dimension, his sharingan could have evolved in the last second because of the great amount of danger he was in. The sharingan always transforms when someone goes through a dangerous moment in their life. There are no plot holes, Kishi planned this out almost from a long time ago, he didn't suddenly wake up one day with the idea "lets make Tobi into Obito!"
