The Rinnegan (輪廻眼, Literally meaning: Saṃsāra Eye) is reputed as the most exalted eyes amongst the Three Great Dōjutsu (三大瞳術, San Daidōjutsu, Literally meaning: Three Great Eye Techniques), the others being the Byakugan and the Sharingan. Rinnegan wielders are said to be sent down from the heavens to become either a "God of Creation" who will calm the world's disorder or a "Destroyer" who will reduce everything to nothingness. Rinnegan are characterised by light purple or red sclerae and irides with a ripple-pattern that spreads over the eyeball and in some cases tomoe.
The Rinnegan was first manifested by Hagoromo Ōtsutsuki, inherited as a kekkei mōra[Notes 1] from his mother's Rinne Sharingan. With his Rinnegan he saved the world from the Ten-Tails and created ninshū, the precursor of modern ninjutsu. For his contributions to the world, Hagoromo became revered as the "Sage of the Six Paths" and rose to mythological status through the centuries, with his Rinnegan coming to be deemed by many a legend or a mutation.
The Rinnegan can be awakened by combining the chakra of Hagoromo's sons, Indra and Asura, in order to create Hagoromo's chakra. Black Zetsu spent centuries attempting to do so, trying to manipulate the reincarnations of Indra and Asura to awaken the Rinnegan. It was not until the time of Madara Uchiha - Indra's reincarnation - that Black Zetsu was successful, when Madara infused himself with the DNA of Hashirama Senju - Asura's reincarnation. However, Madara's Sharingan did not become Rinnegan until decades later, at the end of his natural lifespan; this also seemingly restored the eyesight lost from his use of Izanagi. When Kabuto Yakushi reincarnated Madara, he operated under a similar hypothesis that Sharingan can be evolved into Rinnegan through combination with Hashirama's DNA. To that end he successfully recreated the Rinnegan in Madara's reincarnated body, though these fake eyes didn't have full access to the original's abilities.
Sasuke Uchiha's left Sharingan became a Rinnegan when Hagoromo's spirit gave half of his chakra to Sasuke. His Rinnegan has six tomoe split between its first two ripples. The tomoe will disappear if Sasuke overuses his Rinnegan, preventing him from using its full power until it has fully recharged, something that takes a very long time. Sasuke is still able to use the powers of his Mangekyō Sharingan with his Rinnegan, but apparently cannot use them or even form the Mangekyō in his other eye when it's recharging.
In Boruto: Naruto the Movie, Momoshiki Ōtsutsuki has Rinnegan in the palms of his hands. When he is first seen his Rinnegan are red, but they become the more common purple after he absorbs Kinshiki's chakra. This also grants him a third Rinnegan on his forehead.
As with any dōjutsu, the Rinnegan can be transplanted into others. Madara implanted both of his into Nagato without the boy's knowledge, and Nagato was able to make effective use of the Rinnegan throughout his life due to his Senju lineage. After Nagato's death, the Rinnegan were taken by Tobi, who implanted the left eye into himself and hid the other because he could not handle the power of both eyes at once. Even so, he was able to use one Rinnegan to devastating effects in the Fourth Shinobi World War. Madara later reclaimed both of his Rinnegan after he was revived and ultimately died with them.
The Rinnegan grants the wielder a wide range of abilities without any known chakra requirements to keep the eyes active. Certain abilities are only available to the original owner of the Rinnegan, but the possession of even a single transplanted Rinnegan can grant overwhelming power. Rinnegan are able to see chakra, as well as its flow and tenketsu within the body, but cannot see through obstructions such as smoke bombs. With the Rinnegan, the wielder can master any jutsu as well as all five nature transformations with ease. A Rinnegan user is able to create black receivers, into which they can transmit their chakra across long distances. Possession of the Rinnegan allows Hagoromo's stone tablet to be fully deciphered and renders one immune to the Infinite Tsukuyomi.
Possessing the Rinnegan grants the user a family of abilities collectively known as the Six Paths Techniques: the gravitational powers of the Deva Path; the ability to mechanise one's body with the Asura Path; control over others' souls with the Human Path; the menagerie of summons available to the Animal Path; the limitless absorptive potential of the Preta Path; and access to the King of Hell through the Naraka Path. These abilities can be distributed to the Six Paths of Pain — six bodies embedded with black receivers, which the user can control remotely. A seventh ability, the Outer Path, is said to allow the user to preside over life and death, granting the ability to revive the dead, as well as summon and control the Demonic Statue of the Outer Path, and manifest chakra chains to bind others. The dōjutsu also grants the user a shared field of vision with the Six Paths of Pain, the King of Hell, and the Animal Path's summons, all of which possess copies of the Rinnegan.
Certain Rinnegan abilities have only been demonstrated by single users: Madara can create corporeal shadows in the invisible world of Limbo, which is only visible to the Rinnegan; Sasuke's Rinnegan allows him to shift spaces within a certain range of himself, and create a portal to other dimensions; Momoshiki is able to absorb any ninjutsu with his right Rinnegan and subsequently release it from his left, and use a space–time ninjutsu to travel to and from his own dimension.
- Rinne (輪廻, Literally meaning: Wheel Cycle) is the Japanese term for Samsara, the cycle of reincarnation or rebirth in several Indian religions. This is reflected in the names of all Six Paths of Pain, which share their names with the six Samsaric realms of reincarnation.
- The kanji "Rin" (輪, Literally meaning: Wheel) is also used in Sharingan and Rinne Sharingan, potentially linking the three terms etymologically.
- The anime depicts the Rinnegan as being multicoloured in its first few appearances. This is corrected after the Rinnegan starts being depicted in colour in the manga. However, whereas the Rinnegan in the manga is a uniform shade of purple, the anime tends to make the centre-most ring a slightly darker shade of purple.
- In Naruto: Shippūden episode 203, the Sage of the Six Paths' Rinnegan are shown as red.
- Sasuke's Rinnegan has been shown many times with less or more than six tomoe:
- Prior to Sasuke's Rinnegan appearing in colour illustrations by Masashi Kishimoto, the Naruto: Colour Edition depicted it as being red. This is corrected in subsequent chapters.
