Do you think it's even possbile for Naruto to ascertain the Rinnegan?
We know the SOTSP had the Rinnegan, does this mean that he had the sharingan/MS before he got the Rinnegan?
Or did he simply get the Rinnegan on it's own?
We also know that it's possible to transplant a Rinnegan to a non-Uchiha member (Nagato) so it's possible in theory for Naruto to transplant it to himself.
If not the Rinnegan, what do you think will be Narutos final skill before he becomes Hokage?
