I guess it 2 MADARA in the battle

[Uchicha Macho]

I think madara have split himslef like muu and one halve of him die against the first hokage and the other halve survive.
Other option is izuna carrying out madara legacy and pretending him

 

[shmanton]

no cos if the one who got split died his soul would still be this world and impure world ress wouldn't work
+ its only a jutsu. when naruto does shadow clone his shadow clones get his memories but doesn't mean he splits his soul.

i think what muu can do is a very special clone tech and a strong one at that.
but they do need to reform in order to get full power back.
as he said he can't so he has to wait ages.

even though i don't agree with it your 2nd theory is more believable

if madara still alive then how come kabuto can summon him via IWR ?

 

[Uchicha Macho]

the real madara split himself like muu during the battle against first hokage in order to survive the war

Maybe he's Obito, I mean think about it he seems quite young for someone whos 100 or so right?

it's already been explained by 5th hokage that tobi could be immortal thanks to having hashirama's cells so this could easily explain his age

Ah, thanks I forgot about that lol, my bad.

 

[NaruGoku]

it is possible that he split his soul. for example, he could have had half his soul sealed away--a half which currently resides in Tobi--while the other half went to the "pure world." I'd totally buy that. it could have been part of his plan to live and later become whole via his young body... I'm growing more attached to the idea that they are both Madara. Also, how does Madara know about Nagato? And when Kisame had his brain infiltrated, he saw Madara controlling the Mizukage/3-tails jinchuuriki. I think that was definitely Madara cuz he had the hair and the weapon, also Itachi's flashback to when he met Madara it was definitely Madara... Yeah, they are both Madara somehow

 

[lanakau888]

Tobi is either another madara who was formed from the shodai's cells which is how he knew about nagato.

Or Tobi is izuna uchiha since his supposed death was in Tobi's own retelling, and he probably killed Madara after he gave nagato his eyes.

 

[Totsuka No Tsurugi]

the real madara split himself like muu during the battle against first hokage in order to survive the war

the only that can do that tech is muu

 

[ayingLee]

if it was madara why on earth is he surprise when kabuto shows the 6th coffin and got trick to tell the secret of the setsus, knowing nagato is the only hint that the one wearing the mask is uchiha madara back in the time that he gave nagato the rinnegan, but why on earth that the only information about uchiha izuna was told by the one wearing the mask and the manuscript on the uchiha clan's hideout ah damn cant wait for chapter 560 (clap3x for kabuto for being the brainy one)

 

[Uchicha Macho]

If it obito ,that mean he should be young as kakashi.from what i seen the mask guy donot look like young when he battle against konan.tobi is not the mask guy.
it might be izuna or sasuke dad.sasuke dad because he was the only person i know will be close enough to itachi to help him wipe out the uchiha .Since sasuke is son,sasuke dad will not kill him
that just an alternative predicition

 

[bartel]

Madara is Madara...Tobi is someone else, find out next time!
