Tobi TRUE identity is a man named (forgive me if my spelling is wrong) Shisui Uchiha or Shisui the Telelaportor. Here is my evidence: 1. Shisui is first mentioned episode 129 of the original series. during one of Sasukes flash backs, 3 members of the Village police as well as being members of the Uchicha clan, acuse Itachi of having something to do with the disappearance of Shisui the Telelaportor. They found a note saying he had thrown himself into the river but no body was found. They mention that itachi was close with Shisui and that Shisui was his MENTOR. Now in the episode or chapter where Tobi removes his mask and claims that he is Mardara to Sasuke. He Tell Sasuke that he was Itachi's MENTOR. During this same conversation we are able to judge Tobi's age. HE IS TO OLD TO BE OBITO! as well as the fact that we all know Obito is DEAD. Kakashi Buried him himself. He was crushed to death. Kinda hard to survive that. But he is the prefect age to be Shisui. This will also prove that Shisui would be the right age for his confrontation with the fourth Hokage. Another factor people who believe orbito is tobi leave out is that Obito was trained by The 4th and if he had been alive at the time would still have only been around thirteen a young gennin. So ive given you plenty of proof that Shezwe The telelporter is Tobi. but if you have any questions or think it is anyone else please let me hear your ideas.
