Ok, alot of people are saying that Tobi (Madara) can't be Danzou because of the age thing. Well then you can't actually believe that Tobi is Madara then either.
Because if your going by the age thing then Madara would be dead since he was around when the 1st hokage was. And if your gonna say "oh, no, he can live long because of hie EMS".....then why can't Danzou be Madara? Madara coulda made up the character of Danzou and played that part to now get the title of Hokage he wanted from the beginning.
Then Sasuke comes into play. People have said "Why would Tobi send Sasuke after Danzou and the elders if Tobi is Danzou?"
Because, he doesn't want to do any of the dirty work himself. Sasuke first takes out the other elders, then when he gets to Danzou (Madara/Tobi), probably is some secret location where no one else is around, Danzou reveals to Sasuke that he is Madara, pwns Sasuke, and brings his corpse back to Konoha. This will make Danzou more popular with the people since he took out an S-rank rouge ninja that just killed the other elders.
It's all coming together people, there is some sort of Danzou/Tobi connection. If it isn't Danzou=Tobi=Madara, then its Danzou=Tobi with someone's Sharingan, and neither of them is Madara. Because we've not SEEN anything to prove Tobi's statement that he is Madara. He's not shown his face (though we've seen what Madara looks like from flashbacks), and we've not seen Tobi use EMS or regular MS, just the normal 3rd stage Sharingan.
Btw....I agree, it really sucks that Danzou is the 6th. I thought for sure it'd be Naruto, mainly because in the very first Shippuden episode/manga Konohamaru says "I'm gonna be the seventh Hokage", Tsunade says "Seventh? What about the sixth?", Konohamaru replies "The sixth Hokage will be Naruto"
And again....WTH Sakura, damn it, stop f-n hitting Naruto, he just saved ur @ss, be grateful and don't punch him in the face. UGGHH I'm really starting to hate Sakura. I didn't like her before because she was always hitting Naruto...but com'on did she have to hit him now? Really?
