If an uchiha you need some uzamaki power or its the other around.
Madara got his by first getting the eternal mangekyo sharingan, then when he was about middle aged, he got his hands on some Senju DNA which he implanted in himself. Then, when he had become an old man, his eyes transformed into Rinnegan.
Nagato give pein the rinnegan
You really think Konan has the Rinnegan!? Just for a simple saying , no , Konan does not have the Rinnegan as only Pain(Nagato)has the Rinnegan ever in the Ninja World.
He doesn't even have the Rinnegan
Nagato is the first user of the Rinnegan in naruto
Nagato was the owner of the rinnegan. He used corpses to mure the rinnegan with dead bodies to fight for him. The body of Yahiko was one of them.
no, naruto has not got a rinnegan or any other eye technique
It still is Rinnegan, so yes.
Yes. The real Madara Uchiha discovered the link between the Sharingan and the Rinnegan, before his death. The Rinnegan is an advanced form of the Sharingan, and he was able to awaken that ability.
Nagato is Pein, so if he was Pein, then Pein would already have the Rinnegan.
He was born with it. The Sharingan is a family trait passed down to some members of the Uchiha Clan.
After Konan died Madara (Tobi) found Nagato's body and he transplanted Nagato's rinnegan into his left eye.
The Rinnegan is an ocular jutsu that can link users' vision and thoughts. The Six Paths of Pain use it. So does Nagato.
