Uchiha Obito aka Tobi, the masked man is the main antagonist of the Naruto series. He is a founder of Akatsuki
, a good boy and one of the users of the Rinnegan. He is one of the strongest characters in the series.
He first appeared in chapter 280, where he was referred to be White Zetsu as "a good boy" After a long run of playing the idiot in Akatsuki, Tobi got serious after Itachi's death, and revealed his true intentions. He started a war to capture the Jinchuriki, and is currently in battle with Naruto Uzumaki, Kakashi Hatake, Killer Bee, and Might Gai.
Obito's life can be pretty much summed up by Walter White
"Technically, chemistry is the study of matter. But I prefer to see it as the study of change. Just think about this. Electrons. They change their energy levels. Molecules. Molecules change their bonds. Elements. They combine and change into compounds. Well, that's all of life, right? It's the constant, it's the cycle. It's solution, dissolution. Just over and over and over. It is growth, then decay, then transformation. It is fascinating, really."
For some reason, obito seems to personally know and have a personal vendetta against Kakashi Hatake. The details behind this relationship is that Obito's kouhai (Rin) noticed Kakashi a little bit more than him. This relationship turned for the worse when Kakashi stabbed through Rin. Although Obito stated that he knew it was Rin's sacrifice, he was angered because Kakashi was able to touch her instead of him.

obito had been shown to possess a second Sharingan during his battle with Konan. He used it in order to cast Izanagi and escape from Konan's trap. Exactly what special abilities this left sharingan had, if any, are unkown because the eye was blinded before Tobi could display any other abilities it might have had.

In chapter 599, "Tobi" was revealed to be Uchiha Obito, It was revealed two chapter before this that Tobi had Obito's eye, followed soon thereafter by the mask smash and reveal in 598/599. The sharingan side of his face is wrinkled from premature aging caused by surviving a rock fall, and the rinnegan side of his face is unscatched. He looks like an aged Obito in his late 20's to late 30's.
