he is the first shinobi to get it,he then gave it to nagato for some unknown purposes; maybe it was part of his scheming of world domination. the way he got it was pretty simple in theory: as it is said in the story the sharingan,the mangekyou sharingan and then the rinnegan are the strongest and the most noble of doujutsu. so after getting his eternal mangekyou sharingan he was able to unlock this rinnengan thus becoming as powerful as the rikudu sennin.
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.
He stole it from Nagato's body.
It still is Rinnegan, so yes.
After Konan died Madara (Tobi) found Nagato's body and he transplanted Nagato's rinnegan into his left eye.
no but later in the series after nagato (pain) dies he takes it
Yes. Experimenting with the cells of Hashirama Senju enabled Madara to evolve his Sharingan eyes into the Rinnegan. The original Rinnegan user, the Sage of the Six Paths, had two children, one was the first Senju, the other the first Uchiha, which explains why reuniting the bloodlines did this. He had his Rinnegan transferred to Nagato, but after Nagato's death, Obito retrieved the eyes from him.
Well.. it si unlkikely that he will get the rinnegan since madara stole it from nagato (pein) but he has a very special and mysterious locked power that itachi gifted to him
Madara. Not only does he have the eternal Mangekyou Sharingan, he has the Rinnegan too, as well as the implanted cells from Hashirama Senju.
Yes, when he takes Nagato's Rinnegan and puts it in one eye, his Sharingan in the other.
I believe it is Madara Uchiha because after he killed Konan, he took rinnegan from Nagato and transplanted it into himself. He almost is as strong as the Sage of 6 Paths.
Madara Uchiha obtained the Rinnegan by combining his Indra's chakra with Hashirama Senju's Asura's chakra through the power of the Gedo Statue. This process was part of his plan to gain immense power and achieve his goal of creating the Infinite Tsukuyomi.
Pein possesses the rinnegan and the founder of the ninja world also possessed the rinnegan. No one..at the moment right now in the manga..506..there is no living person with it..only two ppl known to have had it..nagato (pain) and rikudo sennin (sage of six paths) [and founder of ninja world]....both DEAD...the way the manga is leading btw...naruto might possibly have rinnegan eyes waiting to be unlocked.. After Madara kills Konan, he takes the Rinnegan from nagato and does something with it. It is unknown what he is going to do with it, but it can't be good. I am sure that Nagato is not the last we see of the rinnegan.
