[naru998]

as the tittle says
how will that help madara-ojisan???????

 

[Tobi98]

The 2 Sharingan together are stronger than just 1, the Rinnegan should be the same

 

[-immortal-]

he will be able to use the full power of the rinnegan. just like the rinnegan both eyes have ability's which i want to see.
this may the the six path eye that he can use ST etc..s

 

[Ysmir]

He is able to utilize the full power of rinnegan.

You always need both eyes.

 

[Narutoga]

In order to achieve maximum power, madara has to obtain both eyes

 

[TrollKing]

Obviously double the power + bonus of combination of 2 eyes

 

[Zeeshan KTK]

the 2 sharingan together are stronger than just 1, the rinnegan should be the same

this is the true answer .

 

[the last uchiha]

it allows madara to use techniques he cant use without the other eye. from what i've seen madara right eye only controls limbo

so to use other justu like nagatos move set he needs both eyes
