No
No, Madara does not fight Sasuke.
Sasuke and Madara are both extremely powerful. However, it is most likely that Madara would win, as he is probably a bit more experienced and stronger than Sasuke. Although it would certainly be a close fight.
No they will not even fight they are going to team up on madara
Danzo's dead.... Madara would have though. I mean, Sasuke won over Danzo...And Madara is probably more powerful than Sasuke for now. So Chaa.
Madara has a younger brother who's name is Izuna. It is said by Itachi before the fight with sasuke.It is also said by Madara after the fight sasuke and Itachi had.
They're fight hasn't been recorded, but when Madara tells Sasuke about the Uchiha past, the flashback shows Madara with a sword through his chest
WARNING SPOILER ALERT!!!Tobi is not Madara because later in the manga, when the great shinobi war started, Kabuto revived the real Madara so nobody knows now who Tobi really is. And Sasuke meets the masked man in episode 141.
Actually Madara did give sasuke itachi's eyes. In the latest manga madara transplants itachi's eyes to sasuke's.
Naruto has beaten sasuke in a fight(without the help of The Nine Tails) but Madara and another akatsuki came and saved him.
Right after his fight with Itachi, Madara tells Sasuke the truth. I'm not sure what chapter this is from, but you can find it in episodes 140-141.
Naruto and Sasuke's battle is no longer about prowess, because they both have equally formidable jutsus. Sasuke might have an opportunity to fight naruto once again, but if Sasuke remains 'evil', he will lose. If he is hesitant and straddling between good and evil, then neither will win, but madara will become the ultimate target. Sasuke might not be who Naruto battle's if Madara decides to fuse with him in order to create the ultimate power, but it will be Madara. And it may very well be Sasuke battling Madara psychologically if he tries to fuse with his body and control him. there is no clear cut answer.
Seams unlikely, due to the fight between Tobi and Madara against Naruto & co.
