Prime Nagato = mastery of the Rinnegan and all the Ninjutsu, Jiraiya expected him to be able to use. Knowledge: Jiraiya vs Pain; Jiraiya and the Sennin know about the Rinnegan's reputation and Nagato knows about SM's fame (like Itachi knew). The 3 Paths of Pain were beaten because they underestimated Jiraiya's illusion. They believed if it hit Nagato's real body, Jiraiya could have won the battle. ITT Nagato's real body faces off against SM Jiraiya, apart from the Six Paths, he'll use elemental jutsu, clones, the mainstream Ninjutsu he mastered alongside the jutsu you believe Jiraiya taught him. Will Jiraiya be able to land the Genjutsu again and win this time?
