He had already given it to nagato before he met obito
cuzz they dont have too.... its not a question if if they can... its a question of if they want to xd
Rinne tensei requires the sage's body, not DNA
Nagato had sage's body, he could use 7th path of gedo
madara nor Obito could use 7th path gedo, rinne tensei
Where does it say that at???
The Technique itself is like alchemy. kill self to revive another
I don't think that Madara had enough time/stamina to experiment with the Rinnegan at his age, so he implanted it in Nagato to find its secrets
?? where does it say kill self to revive another
Pain was unique, konan said he was the 7th path of gedo, thats where it says it.
madara nor obito has power of 7th path
