Why did Tobi have to use Sharingan in his right eye and Rinnegan in his left eye?Did Tobi find a powerful jutsu when combine the sharingan and rinnegan?I think,Tobi transplant the rinnegan in his right eye because he want to reduce to zero blind spot as sharingan has a blind spot.But still,what is the point to use sharingan when the rinnegan is more powerful?
i think you got
a point there.. since the clan of uchiha were the
ones who were blame for the kyuubi attack. because
of their occular jutsu they can tame the bijuus
just by using a sharingan or genjutsu that only a
sharingan can do... maybe thats whats the use of
him not replacing his sharingan with a rinnegan.
just giving my thoughts.
There is a weakness in the rinnegan,which
is,Tobi use it on the corpse of jinchurikis,just
like Nagato did,6 Paths of Pain.Naruto has beaten
the 6 Pains,which is proven that the rinnegan is
not so powerful.The powerful user of rinnegan
right now is edo tensei Madara,since he is the one
activated the rinnegan and Kabuto power him up to
the next other level from his previous
body.That's why,I think he can't throw
away the sharingan.Sharingan has his own power
that rinnegan don't have.You know,it is
better to use both of it to shorten the period of
time to achieve the main goal.Sharingan is
powerful,Tobi combined it with powerful
rinnegan,so the answer is,Tobi is so powerful.The
only way Naruto to beat the sharingan+rinnegan
users is attack as fast as he can,so the enemies
can't keep up with him.
