LOL. Nothing is WRONG with him. He just seems like an idiot, although it's all an act. He is truly Madara Uchiha. The founder of the Uchiha Clan, and the real leader of Akatsuki. Doom: I agree, nothing's wrong with him, he's awesome. period.
I am positive it is Tobi
Tobi because nobody could defeat him. But i think if naruto fight Tobi Tobi will get kill
Madara is not Tobi.
Tobi :D
No it is not. If you are referring to the episode where Tobi was with Didara in the dango shop when he said "Ichibi, Nibi, Tobi!" then no it was just Tobi being stupid.
No, Tobi does not kill Tsunade.
Tobi was trained by Madara
naruto 99
It is Uchiha, not uchia. Apparently, no Madara is not Tobi, Tobi just took Madara's name.
for real Tobi is the the 1st hokages brother the reason why the 1st hokage died was him and his brother both had the mangekyou sharingan and his brothers sharingan[uchia madra]was not as strong as his so what he did was rip the 1st hokages eyes out and replaced it with his sharinganand that's why he died of his brother uchia madra. AND UCHIHA MADRA IS TOBI. wrong Tobi died and madra was using him as a guise to order around pain and go unknown to konaha.
Tobi is actually Uchiha Madara.
Tobi wields the Makengo Sharingan.
