Because when Pein (Nagato) was little his parents were killed, which resulted in him awakening his Rinnegan and killing the two Konoha ninjas that killed his parents.
He was very alone in the world until he met a dog named Chibi (meaning 'Tiny' in Japanese) and not much longer after he met Yahiko and Konan, his dog Chibi died.
Another reason Pein might have been wounded was because once Jiraiya had completed training them, he left them.
Another wound for Pein was when Hanzo, the leader of Amegakure, claiming to want to discuss peace, Hanzō lured Nagato, Yahiko, and Konan to an ambush.
There he forced Nagato to choose between killing Yahiko or Konan.
Not wanting to force Nagato to make the choice, Yahiko impaled himself with a kunai that was placed in Nagato's hand.
With Yahiko's dying breath, he told Nagato to survive, because he believed in Jiraiya's words that Nagato would become the world's savior.
That is why Pein was so wounded.
Nagato is Pein, so if he was Pein, then Pein would already have the Rinnegan.
Well Jiriya-sama was killed by Pein. So far Naruto is training to get revenge on Pein for killing Jiriya-sama. So we have to wait to see. naruto is cause it turns out that pein and naruto are brothers and naruto kills him!!!!!!!!!!!!
The six paths of Pein was a technique used by Nagato after he became disabeld. He used six corpses, while he himself used the seventh technique to control the others. So there where six peins while Nagato was the real pein.
No. That is a common rumor originating from the fact that all that could be seen of Pein, originally, was his silhouette, which could easily have been the silhouette of Minato (4th Hokage) who is his father. However, once Pein's face was revealed, so was the fact that Naruto Uzumaki and Pein are not related.
If you mean Pein as in Yahiko (Deva Pein's body) then yes. In the manga chapters so far, there is solid evidence that she liked him, and he probably liked her, too, since there was an almost-kiss scene.
Konan is Pein's partner.
Maybe cause jiraiya did die against pein so even if pein is akatsuki leader naruto oughta' find a way
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.
