At the 5 kages summit,Tobi did told a story of Rikudou Sennin and about the 2 brothers.The older brother was given the ocular power but,short life force.The young brother was given a powerful chakra and long life force.Tobi claims that the Uchiha clan was the one from the older brother and Senju clan was the one from the young brother.I think,Tobi might be wrong about the Senju clan is from the young brother.In the story,the clan that have powerful chakra and long life force is Uzumaki Clan.Uzumaki Kushina has proved it when the kyuubi was taken from her.Kushina should be died after the kyuubi was taken from her.But,because of the clan long life force,she still alive after the kyuubi leave her body.Even Naruto has a powerful chakra.The frog that teaches Jiraiya claims that,in order to be a sennin,someone needs strong chakra and a guts not to give up.Jiraiya didn't perfectly in the sennin mode because his chakra wasn't strong enough.Naruto prove it that his chakra was strong enough to gain the sennin mode.
So,I think,Tobi might be wrong about the Senju clan was from the young brother at the 1st time.Tobi only drives by the evidence that the only clan who can keep up with uchiha is senju clan,but it didn't prove that the senju was from the young brother.Senju is just a distant relatif of Uzumaki clan.The story about the young brother has a powerful chakra and long life force most likely same as Uzumaki clan story.Maybe,Tobi attacking konoha 16 years ago because he wanted to prove his theory about the young brother story,which is he want to know whether Uzumaki Kushina will died after he taken the kyuubi from her.As a result,Kushina didn't died.So,his theory about the Uzumaki was from the young brother story is absolutely right.Tobi told the story that the Senju clan was from the young brother story is just a lie to cover up Madara's mistakes.The real story behind Madara and Hashirama battle is I think Madara want to gain Uzumaki Mito DNA.But,he got Hashirama DNA instead.Edo Tensei Madara have said that,he activated the rinnegan a short second before he died.So,whose the person that going to make an experiments on Hashirama DNA,since we know that Madara is death?I'm absolutely sure that person is Tobi.Whoever Tobi is,Madara already planned everything with him,except,Madara didn't told Tobi an info about the Uzumaki clan.I bet,the left side of Tobi body that have rinnegan is an Uzumaki DNA.
But still,that's just my thoughts.There must be wrong info that I put in it.I'm sorry if anything that I said make you guys angry.We can share our own opinion.But,I know,my thought sounds ridiculous..haha..
the sage isnt uzamaki he
tought people how to be a ninja sealing jutsu are
not a kekaigenkai. u guys are missing the most
important part the senju clan got the sages
body!!!!! and life force and the other one then
later on the senju split up u have the main branch
who still had the body and the uzamaki clan with
Dudes and dudettes. everything anyone says on
these posts are speculations. if your name is not
Masashi Kishimoto then you have no idea. and can
only speculate. so dont tell people that they are
wrong when you dont know the truth yourself.
I will add that im not saying dont speculate. but
dont dismiss speculations when you have absolutly
no idea yourself. everyone has their own right to
make speculations. dont try dismissing. rather you
make your own speculations without saying somebody
else is wrong.
I think the sage created the two brothers since he
entrusted his powers to them. It was never said
they were related to him by blood or they were his
sons. Only that they entrusted his powers to them.
In other words created them.
Furthermore, nagato being an uzumaki had a
powerful chakra because Tsunade or someone
guarding her once said he had an exceptional
chakra. Plus, he was able to destroy the leaf
village and almost cause naruto to transform into
the nine-tails. I don't think it is
coincidence uzumakis are child of prophecy. We
don't know if their clan branched off from
younger son, because nagato and kushina had a
powerful chakra like the elder son. Also uzimakis
are known to have a powerful life force. Therefore
they exhibit characteristics of both sons
suggesting they are more related to the sage.
having the sages body is the main point they make
about the senju. having good body
strength,endurance,healing, all sorts of stuff. it
states in the manga the senju got the sages body,
his life force, and his physical strength. chapter
462 page 12 the uchia got the eyes spiritual
energy and strong chakara.
there is a big dif between alot and powerful
chakara no where in the manga does it say u need
powerful chakara to be a sage just alot of chakara
and great concentration thats is why jiraiya a
none uchia could
now one the uzamakis it never states in the manga
that the (clan) had strong chakara it stated they
had strong life forces and where great at seals,
now it did state that kuchina had strong chakara
but she was special even within her own clan thats
why she was chosen to be the jinchuiki not every
one in the clan had strong chakara. now my post
from early stated from the manga the senju got the
body,physical strength, and life force of the
sage. it also states in the manga that the senju
and uchia where the brother and as the bloodline
stated to thin out those to still fought. it ever
says how many years but enough to think the sage
as a myth so probably hundreds and hundreds of
years. the uzamaki are distant blood relatives of
the senju and since they have the strong life
force thats good proof of that. what probably
happened was 2 kids where born one had the body
and the strength the other the life force they
went separate ways and one stated the uzamaki
clan. so they are part of the sage just not a main
