He possesses the Rinnegan, one of the three great dojutsu (eye techniques) along with the Sharingan and the Byakugan.
People believed that is was a myth and the Rinnegan was just a mutation.
He uses a maximum of 6 bodies when battling, they are known as the Six Paths Of Pain- Deva Path (Yahiko's Body), Human Path, Animal Path, Naraka Path, Asura Path and the Preta Path.
Each has its own power, and each of them has the Rinnegan. The Bodies used for the six paths of pain were once strong ninja. The Deva Path can manipulate Gravity, the Human Path has Mind Reading techniques, The Animal Path can summon several different species of animals, the Naraka Path possesses good physical strength and has interrogation techniques, the Asura path is a human puppet which can fire projectiles from his body and the Preta Path has Chakra Absorption Techniques that can absorb jutsu.
Naruto kills pein in a way. Naruto helped kill Pein's other bodies and when he confronted the final body, Pein lost his life when he used his power to resurrect all the people in the leaf who had died because of him.
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.
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.
Nagato give pein the rinnegan
No Neji does not fight pein.
Pein is taller but not by much.
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.
No, he couldn't. Pein killed Jariya instead. Pein stabbed him with 5 chakra receivers.
