He was crushed beneath an avalanche of rocks (an earth style jutsu) after he saved Kakashi by throwing him out of the way.
He is not Obito hes just madara uchia alot of people think he is obito because it kinda fits in with the story but no orbito is dead and to anybody who reads this and you think he is still obito you are an idiot.
Obito dies in the series Naruto
The first Tobi is kakashi's best friend obito the second Tobi is the founder of the hidden leaf village Madara Uchia
Hatake Kakashi's best friend is Uchiha Obito. Obito dies from falling boulders way before the start of Naruto. This is also the why Kakashi gets the Sharingan.
no obito is obito
Yes, Obito is evil. It was revealed in the Manga that Tobi was Obito.
no it is rumered that Tobi is madara uchiha in obito's body but no pein is not obito
Kakashi has the sharingan eye because his teammate, Obito Uchiha, was dying, and his dying wish was that Kakashi took his sharingan eye, because Kakashi had lost his eye trying to save Rin, (his other teammate) and so, Rin put Obito's eye (don't puke) in Kakashi's empty socket. And that is why Kakashi Hatake has a Sharingan eye, even though, he is not in the Uchiha clan.
he is the guy who gave kakashi his sharingan eye then died, that's why you wont see him in the series __ Obito was Kakashi Hatake's best friend (they became best friends...just 5 minutes before Obito dies...how sad). You can read all about him and his big part in kakashi's past in the kakashi gaden, which is chapters 239-244. U can read them here: http://www.onemanga.com/Naruto/239/02/
It is Uchiha, not uchia. Apparently, no Madara is not Tobi, Tobi just took Madara's name.
