Rinnegan

The Rinnegan (輪廻眼; Literally meaning "Samsara Eye") is the most powerful, revered and supreme of all the three main eye techniques (瞳術, dōjutsu). The Rinnegan is characterized by a number of concentric circles around the pupil of the user. It has recently been revealed that in addition to allowing an individual to quickly master various jutsu, the user may also use all six forms of nature manipulation. Like with Sharingan and Byakugan does the Rinnegan also allows the user to sense chakra, including an otherwise hidden barrier, an has the Sharingans abillity to predict an opponents movement. It was first possessed by the Sage of the Six Paths (六道仙人, Rikudō Sennin), said to be the founder of the ninja world and the creator of the first ninjutsu. Currently, the eyes are possessed by Pain.

Pain uses the Rinnegan in his fight with Jiraiya, summoning a total of six bodies that all possessed the Rinnegan. An ability gained by using the Rinnegan is that all the bodies can see each individual body's field of vision. Because of this advantage, one must be blinded in order for a blind spot to be opened. Pain also managed to summon numerous animals each possessing the Rinnegan and presumably sharing their sight.

Notes
Rinne (輪廻) is the Japanese term for Samsara, the cycle of reincarnation or rebirth in several Indian religions.
