I was in a shock when I saw this. I had been pushing for the Rikudou Sennin, or even Madara's brother. Madara's "real body" was the last on my mind, but I don't think it's his "real body," per se. Maybe "original body."
I still don't doubt the identity of Tobi being Madara. He knows too much, has the power of the Senju (and is therefore able to use Izanagi), and has the proper ambition. The shape of the eye, notably, the pronounced wrinkle above and below, which is unique to Madara, is also present on both bodies. Albeit, Tobi has a more wrinkled face, which supports the idea he is very old.
As for Tobi having the power of the Senju...I've thought for a long time that Madara was using limbs made by Zetsu, who is derived from Wood Element (and therefore Senju). This fits when you consider he can break off his arm and throw it at someone, then get a new one. He also didn't seem to be in pain when Torune's bugs were in his arm.
When Madara was resurrected, the first thing he said was "So, it finally happened...it appears that little brat Nagato managed to grow." I recall, upon hearing of Nagato's sacrifice, that Tobi said "I can't believe Nagato used his Rinne Tensei like that. It was supposed to be for me...what a betrayal." Madara was clearly expecting to be resurrected by Nagato's technique, which is a true resurrection, rather than Edo Tensei, which he seemed disturbed about.
With all this considered, I can't see how Tobi is not Madara. The only logical explanation is that he could also use Muu's splitting technique, but I'm not going to claim that he did. Logic has no power over the god of a universe, who can create whatever means to an end he pleases.
It does seem likely, though. Even though the original resurrected Muu's soul was sealed, the split half is completely free from it, and its power is lower. This seems to be the case for Tobi, as well.
GO READ GAIDEN AGAIN. THE NINJA THAT SLASHES
KAKASHIS FACE WHEN HE IS ABOUT TO ATTACK
OBITO'S JUTSU IS LABELED ZUZUZUZUZUZUUZUZU
AND AFTER GAIDEN ENDS THE ONLY TWO PEOPLE
REMAINGIN AT THAT FIGHT ARE OBITO WHO IS
SUPOPSEDLY DEAD ALONG WITH THE GRASS NINJA WHOSE
JUTSU GOES ZUZUUZZUZ JUST LIKE THE ZETSU WE KNOW
NOW. IM SAYING IS THAT GRASS NINJA USED SOME FORM
OF JUTSU THAT MADE HIM ZETSU SPLIT HIMSELF INTO
TWO. SO AN ALL BLACK ZETSU ORIGNALLY EXISTED SPLIT
HIMSELF AND THE OTHER HALF OF BLACK ZETSU JOINED
THE CRUSHED SIDE OF OBITOS BODY. TOBI DOESNT
BECOME KNOWN AS MAADARA UNTIL YOU SEE KAKASHI USE
A MYANGEKYO FIGHTING MADARA. TOBI/MADARA IS OBITO
AND WHEN THIS SHIT HAPPENS AND COMES OUT I CANT
WAIT FOR YOU ALL TO REALIZE MY ZETSU THEORY IS
RIGHT BECAUSE THERE HAS NEVER BEEN A REPEATED
JUTSU LABEL IN THE ENTIRE MANGA AND YOU THINK
KISHIMOTO IS GONNA HAVE AN ARC ABOUT KAKASHIS
CHILDHOOD AND HOW HE GAINED A SHARINGAN AND GIVE A
GRASS NINJA A DISTINCT JUTSU NOISE LABEL AND THEN
USE IT AGAIN FOR A COCMPLETLEY SEPEREATE CHARACTER
NOOOO! HE IS A GOOD WRITER AND HE IS FORSHADOWING
IN GAIDEN WITH OBITO BEING PRESUMED DEAD AND THE
GRASS NINJA USING ZETSUS ZUZUZUZU JUTSU
the closest tobi is to madara is a clone thats it.
he is not madara because madara was summoned back
from the dead u summon the soul. that would mean
ur dead. the reason every one believed he was
madara was because of the abilities that he has.
the and ur not even talking about the eyes ur
talking about the skin around the eye thats stupid
Why is it stupid to point out a trait
unique to him? Stop being a fool.
Minato believed it was Madara because only
Madara and Hashirama have ever controlled the
kyuubi. With Hashirama long dead, who else could
accomplish that? I don't remember if Itachi
implied that controlling the kyuubi was the power
of mangekyou or eternal mangekyou, but it was one
or the other.
Only four Uchiha have
ever gotten mangekyou: Izuna (who was left without
eyes), Madara, Itachi, and Sasuke. Itachi and
Sasuke were too young when Tobi attacked with the
kyuubi, so that leaves Madara and his brother, who
was presumed dead and had no eyes whatsoever.
However, Tobi doesn't look like
Izuna. He looks like Madara. He claims to be
Madara. You know what they say: if it looks like
a duck and sounds like a duck...it's a duck.
Hell, he even wears the same gloves.
Madara's power is shrouded in mystery. As
possibly the second-longest-living ninja (after
the rikudou sennin) ever, who knows what he's
learned over the years?
Not being able to explain something and
something not being possible are not the same
thing. My belief that Tobi is Madara is a theory,
one that I've supported with many pieces of
evidence and many logical conclusions that
haven't been contested, and I've given
plausible explanations for any arguments that he
may not be Madara. I'm 99% sure that Tobi is
Madara, only because Kishi can invent any number
of reasons or characters (or anything) and make
him not to be. It's just as likely that Tobi
is Madara as Tobi being the third mizukage, who
was only pretending to be controlled and was
really controlling Tobi, and who used a
clone/puppet/immortality technique to keep her
real identity secret.
there's evidence to support that Tobi is
Madara more than any other candidate, so
that's what I'm sticking to.
