How much of the Sharingan do we understand right now - specifically of the Mangekyou Sharingan?
Well, let's take two Uchiha brothers we know: Sasuke and Itachi - * Sasuke and Itachi's Mangekyou Sharingan both are capable of the Tsukoyomi, Amaterasu, and Susano.
Upon this very observation we are reminded of another set of Uchiha brothers we now know: Madara and Izuna Uchiha - * Madara and Izuna's Mangekyou Sharingan are both capable of the Tsukoyomi, Amaterasu, and Susano.
Now it appears that the Mangekyou Sharingan in each eye is given a unique abilies and Susano if the Mangekyou Sharingan is unlocked in both eyes - as noted by Sasuke during his fight with the five kages. This would also suggest that the heritage of the Uchihas in specificity is supposed to play a role in their Mangekyou Sharingan abilities.
This would also imply that Madara and Izuna are the direct Ancestors of Sasuke and Itachi - the crazy physicial similarities between Sasuke and Izuna would also suggest this. It is a conclusion I have come to as well.
Now there is two other Uchihas I want to take a loot at: Shisui and Obito Uchiha.
Obito: * Has only 1 mangekyou sharingan unlocked and thus only 1 ability; we know this must be his space-time jutsu.
Shisui: * Unlocked both mangekyou Sharingan and this must have had 3 abilities; we know one of these is a very powerful genjutsu by experience and another is Susano by default.
I am making this thread mainly to make this theory: Shisui and Obito are brothers.
Now remember even killer Bee had heard of Shisui Uchiha and knew him as "Shisui the Teleporter". Now why in the living hell would you call him a teleporter, you might ask. It's a highly likely scenario that Shisui was called this because his second Mangekyou Sharingan ability WAS space-time ninjutsu. I believe that if Kakashi and Obito's eyes are re-united, they will unleash the Koto-Amatsukami yet again. Do note that Itachi noted that the Koto-Amatsukami can only be used once every decade UNLESS YOU HAVE HASHIRAMA'S CELLS - Obito totally has them!
Could be, I always wondered why Madara, Sasuke and
Itachi's techinques were the same but not the
rest, you probably nailed it in the head with
this. Maybe that is why Obito is able to solify
his body and all cause maybe Shisue really
teleported as well, and I wonder how Danzo managed
to steal his eye, all this Uchiha shit is wack
Senjus got it on lock.
well i think that it all made sense until u got to
obito and shisui being brothers bcus if u read
shisuis bio it tells u that when he was know as
shisui the teleporter it was refering to the
"flicker" ability in which itachi tried
to master after seeing shisui in action and itachi
uses several times. the flicker ability is similar
to flash step in bleach, in order to go further u
wld have to use more chakra. But anyway shisui wld
use this move in rapid succession and he wld kill
his enemies and to them it looked like he was
^ I don't remember that being explained, my
bad. It sounds kind of whack that they'd say
that about a stupid body flicker user when just
about EVERY high level ninja can use that - and
many transcend it.
That does not
necessarily deny that they're brothers.
Further evidence can be seen in the level of
physical similarities between the two Uchihas. We
further know that Obito and Kakashi can't use
any more Mangekyou abilities than Kamui because
neither has the either eye for both the second
technique as well as the complementary susano, as
well as the fact that Shisui's only
demonstrated one Mangekyou Sharingan ability even
though he has 1 more unique ability with Susano
and his shown tech (koto-amatsukami)is stupid
levels of powerful. Don't you think
Shisui's second ability could have been the
kind of jutsu that legends are made of?
Oh and btw readers do note that the Obito Shisui
thing is seperated into its own segmented labeled
"theory". On the ancestry of Madara and
Sasuke, I'm pretty heavily convinced that
it's about as obvious that Madara is
Sasuke's ancestor that it was that Minato was
Ofcourse Sasuke is related to Madara he was from
the main branch of the family Fugaku was the clan
leader then the next head should have been Itachis
as the older brother thats the reason i Think they
have similar eye abilities ^^ and ofcourse Shisui
and Obito I think there something more to that
story of why Obito became evil i dont believe that
Madaras bullshit why cuz Madara was with
Orochimaru thats all im gonna say cuz i dont like
