Please dont start this Madara is Tobi or Danzou crap.
1) Madara showed his face to Sauske, y would Madara set up a fight between Sauske and Danzou?? I say this cuz some r saying that Madara is Danzou, further explaining that Sauske will try to kill Danzou who is really Madara according to some of you. THINK ABOUT IT!!!
2) Some of you say that Madara is old cuz when he took of his mask to show Sauske you could see some wrinkles around his eyes, meaning that he might be old and might be Danzou (go back to #1 point). So he's old according to some, how does that explain Madara being Obito, Obito is the same age of Kakashi (26 or 27 yrs old).
3) One thing that im kind of sure is that Tobi is Madara LOL I mean thats he's cover up name to blend into Akutski without anyone knowing.
4) True Madara or should I say Tobi whichever has the Sharingan on the same eye as Danzou, but it doesnt prove anything. Especially with Danzou talking about looking for Kabuto because Oro and Kabuto were helping or doing something to fix his eye and arm. Bringing me to my next point. WHY would Danzou have such a hard time finding Kabuto if accoring to some of you he is Madara. If he really is Madara he would have found Kabuto a long time ago.
5) If Danzou is Madara like some of you say he might be, then Nagato AKA Pain should had recognized him since Madara was his real boss and was using him. Im sure Madara showed his face to Pain, therefore Pain would had recognized him and tried killing him since Danzou (Madara) was working with Hanzou to become Hokage. If Danzou was really Madara he wouldnt have almost any problems since Madara is real powerful.
There's many other points I can make but it would just be a waste of time, whenever people read, pay attention and absorb what u read.
