Part in the story:

Obito was a 12-year old Genin in Team Yondaime with Kakashi, Rin and of course, Yondaime(of course at this point he wasn't Hokage yet). He's quite like Naruto, goofy and desperate to prove he is a worthy Ninja, mostly unrespected by peers and teachers alike. However, he is ready to put his life on the line for his teammates without hesitation. Obito carries the blood of the Uchiha and has the power of the Sharingan within him. Kakashi saved his life, but when they were fighting with a Rock ninja, Obito saved Kakashi's life and he was hit by a torrent of falling rocks. The whole left side of his body was crushed, and presumably Obito died. When Kakashi went to his fallen teammate's side, however, in confrimation of their friendship and as a gift for Kakashi gaining Jonin rank (Obito was the only member of the team not to have given Kakashi a gift), Obito gave Kakashi his left eye, and the Sharingan with it.

Some fans speculate that Obito is Tobi because Tobi's mask only has one eye hole (over the right eye) and because of Tobi's carefree and goofy humour. Also, Tobi and Obito share many of the same letters.
