I've been doing some research on the Rinnegan, and this info may be useful for future creations.
"The Rinnegan is characterized by a ripple-like pattern around the pupil, with a grayish-purple iris and sclera. In addition to enabling the user to quickly master various jutsu, the user may also use all six forms of chakra nature transformation which, as noted by Ibiki Morino, literally allows its user to use any technique they wish. It also allows the user to use all of the six paths techniques, a series of ninjutsu unique to the Rinnegan user. Like the Sharingan and the Byakugan, the Rinnegan also allows the user to see chakra, including otherwise hidden barriers. According to Nagato's partner Konan, the possessor of the Rinnegan can also control the seventh path of Pain, who is "beyond life and death", that can use the Outer Path: Samsara of Heavenly Life Technique, which allows the Rinnegan user to revive all people who have recently died." From http://naruto.wikia.com/wiki/Rinnegan
It seems that some of the more powerful techniques such as the Six Paths jutsu is not limited to only Nagato, but merely to the Rinnegan.
No rinnegan users can have a Six Paths of Pein jutsu. Its a copy and paste of nagato and c/ping is not allowed on this fanon. The jutsu is only allowed if the 6 paths do not have the same abilities as Peins paths--不滅王 くらやみ - "Immortal King of Darkness" (吐露 - "Speak Your Mind"|業績 - "My Achievements") 16:46, May 12, 2010 (UTC)
