Nagato is Pein, so if he was Pein, then Pein would already have the Rinnegan.
Konan is Pein's partner.
Pein is not a word in the English language. However, Pein is the leader of Amekagure in the anime of Naruto.
Pein's fullname is never revealed. Pein is really Nagato, and just an alias that was created.
No Neji does not fight pein.
Nagato give pein the rinnegan
Pein is taller but not by much.
I heard that Konan and Pein make a great couple, but in Naruto Shippuden, Pein dies without Konan saying she liked Pein, there is no proof.
No, Tobi does not kill Pein. Pein sacrifices himself when he revives everyone he kills in Konoha.
No, because Pein killed Kakashi, proving one thing. Pein is stronger.
No Sasuke does not kill Pein
Nope. She will not beause Pein is dead.
