So who's the sage bro?

[Devauzamaki]

If nardo and sauce are the younger sons,who the rikudou bros?
I think naruto and sasuke about to evolve beyond their younger son and elder aspects.
They been basically seen as them since obito introduce them in the land of iron.

So their final power up should be
Hagaromo=Naruto
The Sage Brother=Sasuke
What you think?

 

[FatherOfMurder]

The Sage's brother is the hyūga clans ancestor. U_U

 

[-immortal-]

in fact Its madara

I think the Sage's brother had two sons who were the founders of the Hyugga and Uzumaki clan.
