The eyes that the Rikudou Sennin himself and later Nagato and Pein possessed. Said to control the seven paths. One of the three dojutsus of Naruto
The Rinnegan are the eyes of reincarnation and is said to be the most illustrious of the 3 dojutsus. Originally these eyes were held by the sage of the six paths, a man who founded the ninja world by inventing ninjutsu, but are now held by the Akatsuki figurehead leader Pein. The Rinnegan is said to be a tool of God that can either bring salvation or annihilation.
The Rinnegan is characterized by six "rings" that surround the pupil. These "rings" each represent one of the six paths of Buddhist reincarnation: Deva, Asura, Human, Animal, Hungry Ghost, and Hell: all of which it derives much of it's powers from.
The first ability of this amazing dojutsu is the ability to use all 5 elemental chakra types and can learn ninjutsus at a much faster rate, and like the Sharingan and Byakugan it can see chakra. But it's most notable abilities are: gravity manipulation (Deva), body modification (Asura), telepathy (Human), summoning (Animal), chakra absorption (Hungry Ghost), and resurrection (Hell).
