One of the Three Great Eyes in Naruto, the Rinnegan is the strongest eye of them all. It was first said to be wielded by Hagoromo Otsutsuki, the Sage of Six Paths. Using the Rinnegan, the user can learn any jutsu they want and they gain access to special powers, known as the Six Paths Powers. A Rinnegan user is said to have control over life and death itself, which makes only the strongest of characters worthy of this eye. Although the Rinnegan is just one dojutsu, there are several variations that can be noticed in different characters who have wielded if so far. Here are the ten strongest Rinnegan users in Naruto.
10 Black Zetsu
One of the main antagonists of Naruto and the will incarnate of Kaguya Otsutsuki, Black Zetsu managed to get his hands on the Rinnegan towards the end of the series. Through controlling the body of Obito, Black Zetsu cast the Rinne Tensei no Jutsu to bring Madara back to life. As expected, his skill with the Rinnegan is very limited, and he doesn't do much other than controlling Obito's body. As such, it's not surprising to see Black Zetsu at the bottom of this list, making him the weakest user of this godly eye in the entire series.
9 Jigen's Ten-Tails
In Boruto, Kara's leader Jigen seems to be incredibly powerful and among his many powers, the ten-tails seems to be one as well. Although it is unknown how this ten-tails differs from the original one, Sasuke is sure that it possesses the Rinnegan, at the very least. While smaller in comparison to Kaguya's ten-tails, this one is likely just as powerful, and its Rinnegan, having tomoe, must be just as strong. The ten-tails is capable of swallowing oceans and destroying planets, and if this one is on the same level as the one on Earth, it is more than likely unstoppable.
8 Nagato Uzumaki
Also known as the Third Six Paths, Nagato Uzumaki was one of the most fearsome characters in the entire series, mainly due to this Rinnegan. Unbeknownst to Nagato, his Rinnegan was bestowed to him by Madara Uchiha. Thanks to his Uzumaki body, Nagato was capable of entirely using the power of this eye, going as far as mastering each and every aspect of it.
When at full power, Nagato was capable of taking on two Perfect Jinchūriki in Naruto and Killer Bee. Nagato remains to be the only person to use this eye to its absolute potential, as seen in his battle against Jiraiya, and Naruto.
7 Obito Uchiha
Madara's successor to the Infinite Tsukuyomi Plan, Obito Uchiha was one of the main antagonists of Naruto. After Nagato's death, Obito took it upon himself to take the Rinnegan and make sure that the Tsuki no Me plan comes to fruition. Although not as adept at using the Rinnegan as Nagato, he did manage to create his own Six Paths, which gave even Naruto some trouble. As the Jinchūriki of the Ten-Tails, Obito grew so strong that his powers could only be matched by a few individuals, such as Naruto Uzumaki and Sasuke Uchiha.
6 Madara Uchiha
Madara Uchiha was one of the handful of people in Naruto who actually awakened the Rinnegan on their own. By fusing Ashura's powers with those of Indra, Madara got access to the Rinnegan, which he could use to the best of its abilities. As the perfect jinchuriki of the Ten-Tails, Madara was edging closer to the level of Hagoromo at a drastic rate, indicating how strong he really was. Using his Rinnegan, Madara could also use a special ability known as Limbo, which allowed him to summon clones of himself from a completely different realm, making him nigh unstoppable.
5 Sasuke Uchiha
Widely famed as the only shinobi capable of rivaling Naruto Uzumaki, Sasuke Uchiha achieved godly status by receiving the Six Paths Yin powers from Hagoromo Otsutsuki. Thanks to these powers, he awoke the Rinnegan in his left eye, although his version of this eye consists of six tomoe. As expected of someone like Sasuke, by adulthood, Sasuke has mastered all the powers of his Rinnegan.
From using the Six Powers to his special teleportation technique called Amenotejikara, Sasuke can do it all. If that wasn't enough, his skill with the eye is such that he can open portals to different dimensions to go anywhere he wishes. Truly, Sasuke is one of its most formidable users.
4 Kaguya Otsutsuki
The progenitor of chakra on Earth itself, Kaguya Otsutsuki also possessed a power similar to the Rinnegan. Her eye, officially known as the Rinne-Sharingan, possesses the ability of both the Sharingan and the Rinnegan, making it better than both these eyes in the making. Using its powers, Kaguya could open portals to six different dimensions, and even instantaneously teleport herself and those around her to anywhere she wanted. Being an Otsutsuki, she could absorb all chakra, and hence all ninjutsu were rendered useless against her. The biggest capability of her Rinne-Sharingan was the ability to cast Infinite Tsukuyomi.
3 Momoshiki Otsutsuki
One of the members of the main family of the Otsutsuki clan, Momoshiki is arguably their strongest that we've seen. Being capable of fighting both Adult Naruto and Sasuke head-on, Momoshiki appeared to be an awfully strong foe. At his disposal, Momoshiki had 3 different Rinnegan. Using the one on his left hand, Momoshiki could absorb all chakra, and using the right, he could make the Jutsu multiple times stronger and expel it. Yet another Rinnegan was on his forehead. However, what it did remains largely unknown. Nonetheless, Momoshiki was an outstanding Rinnegan user, and one of the strongest in the Boruto series.
2 Urashiki Otsutsuki
One of Momoshiki's underlings, Urashiki seems to be an incredibly powerful God, being capable of fighting against two of the Five Kage with ease. Unsurprisingly, much of his power is derived from his Rinnegan, which he possesses in both of his eyes. Unlike Sasuke, Urashiki wields the tomoe-Rinnegan in both eyes. As expected of an Otsutsuki, Ninjutsu is practically useless against him. Urashiki's Rinnegan lets him teleport to places instantly, and when combined with his ability to steal the chakra of people and use it, he is undoubtedly one of the strongest in the series. Urashiki has stolen Mitsuki's sage chakra, as well as a big portion of Sasuke's chakra which, if used, would make him nearly invincible.
1 Hagoromo Otsutsuki
Also known as the Sage of Six Paths, Hagoromo Otsutsuki is arguably the strongest character in the entire Naruto series. Wielding the Rinnegan since he was a kid, Hagoromo's skill with this eye is unmatched. A fraction of his powers was shown to us when he created the moon using a Chibaku Tensei. Even after distributing his own power between Naruto and Sasuke, Hagoromo had enough chakra to summon the dead Kage from the pure lands and break the Edo Tensei. Without a doubt, he's the strongest Rinnegan user in the entire show.
