Tobi is!!!.....

[twistedlink]

Madaras younger brother!!

No really.

Why would taking his brothers eyes kill him?

It would simply make him blind, Obito didnt die once Rin gave kakashi his sharingan, he stayed alive til he got crushed.

Eye transplants dont kill the donor.

So Madara dies against the 1st, and his brother comes along and steals his eyes back, with Madaras lenses too, EMS!

EDIT:
A hint to this is that guys Byakagun!

Its symbolic, he has a donour byakagun to see through danzos hidden eye.

Its saying Byakagun is the key to tobis eye.

So, hyuuga clan, the brothers SWITCHED, (upper and branch family).

I believe Madara and his brother may have switched, so everyone who thought was Madara was actually his younger brother, so the younger brother is technically Madara.

mwahahaha!

[+luffy+]

kisame already recognized tobi as madara

so their is no doubt that tobi is madara.....

[Hellsbadass]

but didn't they show izuna/ madara's brother in a coffin wit his covered?

[Kazamori]

Tobi is Madara's son ehhh... it could be anything

[UnknowNinjaName]

i just dont get it why itachi didnt say kisame about madara when kisame was good with madara before?

i believe tobi is madara but some things are just weird... tobi needs to take hes mask cuz kishi can suprise us and make tobi as actually uchiha shisui ...

[Hellsbadass]

it cannot be uchiha shisui bcz danzou took uchiha shisui's right eye O.o and tobi has only his right eye

[Crutch Kaguya]

Tobi is Madara, and he is not he could be shusui cause we only see one eye

[Excitè]

Only Time Will Tell It Would More Sense If It Was His Lil Brother

I think that some details (theory's) are missing, but to me this is a refreshing theory. I'm much more interested in this such as how did he get the eyes, did he get EMS, are both brothers in existence? This way it is consistent with the first killing Madara.

I think somewhere of data book it was said that Izuna died on battlefield not long ago after eye transplant to madara. He fought bravely but blind eyes betrayed him :P

[mackjack405]

no no no... tobi is sasuke's dad... cant u see the star wars like scene coming.... "SASUKE! I AM YOUR FATHER!"

[Typhon]

I've already said it, Tobi is both Madara and Danzo!
