It has not been revealed in the Naruto manga or anime if Madara Uchiha dies.
Now that he is about to master kyubi's chakra He can if he does that successfully
The author never revealed if Madara Uchiha married anyone.
This is less likely because Sasuke Uchiha is the BEST and Naruto will NEVER beat him!
Yes
No never
Tobi and Obito are not the same person. Tobi is Madara Uchiha. It was confirmed by himself. He will be unmasked later in the series.
Well there are many strong ninjas in Naruto, The 4th Hokage was very strong, so were Uchiha Madara and the First Hokage. The strongest one EVER (present and past) is probably the Sage of Six Path. Who had sealed the Jubi and used its powers to bring peace.
sauske and neji and many others i think also orishimaru but he had help fightin here
no she died trying to protect naruto from madara
No because he was sealed into Naruto during the nine tailed fox attack on the Hidden leaf village, Update: jan 30th: 2013 the Fourth homage has just been Revived in chapter 618 hopefully he will help naruto Kill the Ten tailed Juubi and Madara uchiha
hey madara cant be because Tobi is to childish he plays a lot. Madara is mature so madara is not Tobi. obito now he is childish he may be Tobi. they should make a movie that naruto older self comes and he is the akatsuki leader then naruto fights him self and he turn to the 7 or 8 tail fox that will be cool. Dude!!! Tobi is madara he acts all childish so nobady knows him hes the strongest akatsuki character ever!! he fought the first hokage with the nine tailed fox but then the first hokage defeated him everyone thought he was dead but he,s not he is Tobi and anyway obito died by the boulder how can he come back alive
