No he is not cause Madara was dead and I am saying so because Madara was resurrected by Kabato via Impure World Resurrection jutsu (the same jutsu Orochimaru used during his fight between Third and himself and resurrected the dead 1st and 2 nd hokage). This jutsu can work only on dead peoples, it can't resurrect a body without its soul.

He may not be Madara, but he's definitely someone from the Uchiha clan. Otherwise, one wouldn't be able to use such powerful jutsu with those eyes. A while back, I thought that maybe Tobi was Izuna Uchiha, Madara's little brother. But he is known to have died way before Madara did. But seriously, the way Tobi explained how Izuna voluntarily gave his eyes to Madara etc would only make sense if he's one of them. Who else would know such detail of what went on between the brothers who "died" generations ago?

i think of he's Obito. I advise there have a great number of tricks like how basically the attention that Obito might have left exhibits and he's goofy like Obito. The bankruptcy the place all and sundry says Tobi says that he's Madara he rather suggested "My skill, Uchiha Madara's skill, the sharingan's skill." those won't be the precise words yet you get the element. I additionally think of Uchiha Madara could've taken over Obito's physique basically till now he replaced into approximately to die. I advise c'mon that guy is like a hundred years old so as that can not be his physique.

I'm almost 100% sure that he is not. Along with what everyone else said, I believe Tobi used the name Madara because it was a name people recognized and feared. In other words, it is a name that had power IN it, which helped some. This is in one of the chapters, I believe it is what Tsunade said.

SPOILER:

He is most likely not as the real Madara was resurrected via Edo Tensei. I say he is "most likely not" because you never know what to expect with this writer, for all we know there could be TWO Madaras (Madara and Tobi).

tobi is not madara hes just some guy becouse the real madara is dead hes fighting the five kakge

Tobi is a nobody, he wants to be known as a nobody that is what he said when Naruto kuun asked for his name. So, to me he is just Tobi.
