NarutoAs far as speculation goes, what you say is possible but highly unlikely.
It would be hard to explain how a low level ninja like Obito, who barely even managed to unlock one tomoe before his supposed death, is able to have enough visual prowess to control the Kyuubi, bypass Konoha's barrier undetected, have powerful teleporting abilities, and fight on par with Minato all after three years. We have yet to see any ninja achieve such a high level of power and skill in that amount of time.
Also, we know Tobi has wrinkles on his face, implying that he is a older aged man. If he is indeed Obito then he would still look young, seeing as his age is close to Kakashi's.
Also...remember when Kakashi goes to unleash his Mangekyo on Tobi and Tobi basically gives him the 'talk to the hand' treatment and knew not only what Kakashi was about to do, but also that it had no chance of working on him
I don't think you understood. I'm not saying he's Obito, but maybe a relative with the same type of T/S jutsu.
Kakashi used Kamui during his fight with Deidara and Sasori, can't remember if he used it also with Kakuzu.
Anyway, as it was said so many times, Akatsuki was not a street gang made by a bunch of idiots, but a very powerful and well-prepared organization led by Tobi. They had lots of intel from all the villages their members were previously part of. To gather all the Tailed Beasts and control the world is not a path you can take so lightly.
Tobi knew what kind of jutsu Kakashi had so there's no point in continuing with your useless mirror-climbing to Tobi = Obito's theory...
Plus, when Kakashi rescues Sakura and finally encounters Sasuke, White Zetsu was there from the beginning to watch over Sasuke. There Kakashi tells Sakura it's his duty to repair to the damage he did by failing over Team 7. Sasuke's there listening, Zetsu's there listening. Kakashi's always been regretful for what happened. Oh, and Kakashi absorbes the first Susanoo's arrow with Kamui.
Did anyone Noticed Caption Namikage Uchiha below the Picture of Tobi?????
I wonder what is the reason behind tht!
