by saying the real pain wasnt "there" meaning behind the scenes.
pain revives jiraiya
no, because jiraiya was killed by pain in the manga.
no
Yes, Pain kills him.
Yes pain killed him
He has the potential to be stronger but he doesn't have time to compare before Jiraiya dies
Jiraiya is dead. Pain killed him.
Nagato (The main Pain) coincidently fought the same guys that Jiraiya fought during his journey. Nagato used the corpses of the guys he killed and turned them into the Six Paths of Pain.
Pain killed Jiraiya because Jiraiya was considered an enemy to Akatsuki and an infiltrator to the Hidden Rain country. He knew some of the secret of Pain's God technique and was an enemy of his goals, sadly :(
Jiraiya fights Pain/Pein from episodes 126-133 BUT IF YOU WANT JUST THE FIGHT WITHOUT THE INTRO WATCH EPISODES (watch 129 if u want to watch konan fight too) 130-133
No, he is Madara Uchiha, who was born long before Jiraiya. Their former acting leader, Nagato/Pain, was a student of Jiraiya, although not a Konoha ninja, but a orphan from Amegakure.
He wrote a encrypted message of Pain's secret on fukasaku's back, which was shown to Naruto and Konoha. Edit: Jiraiya wrote "The real one's not among them" referring to the Six Paths of Pain.
