Naruto- Rumours Dispelled

Every day I read a lot of Naruto material: fanfiction, comics and Q & A. In the Naruto kingdom of Fandom, there are so many fantasies, many believable enough to be true. This post is for the more popular ones, and if they are true or possible.

1. Tobi= Obito??????
Rumour: Tobi, a member of Akatsuki, is also Kakashi's old teammate, Obito.
Reason: When Rin was captured during a mission, Obito decided to rescue her, while Kakashi, went on to complete the mission. Kakashi later changed his mind and rushed back to help Obito. They faced an enemy that could become invisible. During this fight, Kakashi's left eye was blinded. Obito gained and used his Sharingan to defeat the enemy and the two teens carried on with their rescue. They came in time to save Rin, but the final enemy made the cave that they were in begin to collapse. During the escape from the cave, Kakashi was hit by a pebble on his damaged eye and fell. A huge boulder was about to crush Kakashi. Obito threw Kakashi out of the way of the rock, but was crushed. The team spent a few minutes trying to free him and talking to him, as his left side was free of the boulder. Obito offered Kakashi his Sharingan eye in place of the one Kakashi had lost. Rin, who knew medical jutsu, performed the operation. Just as it finished, the cave began to truly collapse and the remaining two teammates were forced to leave Obito. His body was never recovered.
Tobi was, for a while, a complete mystery. He wears a bright orange mask with only one eye hole, on his right side. Remember, Obito gave his left eye to Kakashi. Tobi wears strange full-body black armour. If Obito's body was badly scarred or disfigured, this would make sense. Obito and Tobi's hair look almost exactly the same and they both wear some orange. Tobi's playful manner and the fact that he is never serious also match Obito's personality.
My Verdict: Although I have wished this rumour was true over and over, it isn't. Later in the manga, Tobi is revealed to be Uchiha Madara. Although he is an Uchiha, he is immortal and not Obito.
