Nagato controls the pains, he is also the founder of the akatsuki.
Pein is just a dead body same as the 5 other peins the one who's controlling them is Nagato
Nagato is Pein, so if he was Pein, then Pein would already have the Rinnegan.
Yes. Pein (or Nagato) dies after his encounter with Naruto. The reason I said Nagato was because Nagato is the one controlling all the Peins. After Naruto tells him his resolve and his look on pain and hate He was influenced and used a jutsu that brought everyon killed by the Peins back to life but it cost him his life. However, Jiraiya remained dead from his previous battle with Pein.
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.
Nagato give pein the rinnegan
No Neji does not fight pein.
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, because Pein killed Kakashi, proving one thing. Pein is stronger.
No, Tobi does not kill Pein. Pein sacrifices himself when he revives everyone he kills in Konoha.
