Rinnegan is one of the most powerful dojutsu that only a few shinobi possess in the Naruto anime. It originated from Hagoromo Otsutsuki, also known as Sage of Six Paths. Rinnegan can only be awakened by a few shinobi because it requires a tremendous amount of chakra and exceptional talent. Uchiha Sasuke, Uchiha Madara, Uchiha Obito, Nagato Uzumaki are the strongest shinobi in the Naruto anime who possess the Rinnegan. However, each user of the Rinnegan has distinct abilities.
If other Rinnegan users can awaken it when their powers have matured, like Sasuke who obtained it during the Fourth Great Ninja War when he met Hagoromo, Sasuke could only awaken the Rinnegan in one of his eyes. On the other hand, Nagato was blessed with Rinnegan in both his eyes since he was a child. With the six paths’ power that Nagato possesses, it can be said that he retains control over life and death. The user can bring back the dead by exchanging their life with theirs. For instance, Nagato revived the Konoha citizens who died due to Pain’s attack by exchanging their lives with his. He saved most of the Konoha citizens in just a few seconds.
Nagato is a member of the Uzumaki Clan, known for their vast chakra reserves. However, Nagato is not a descendant of any shinobi. His parents were ordinary humans who were killed during the war between Amegakure and Konohagakure. Although Nagato’s parents were ordinary humans, he obtained the Rinnegan’s power as a child and successfully awakened it during the war. As a member of the Uzumaki Clan who possesses enormous chakra reserves, Nagato can elevate the Rinnegan’s power to higher levels. He can use the six paths’ technique simultaneously by distributing it to the six other bodies that are already dead.
The six paths’ technique is the fundamental power of Rinnegan, and Nagato can even use it on someone else’s body by controlling it from a distance. The six dead bodies receive chakra from Nagato via a black device. Each body that receives Nagato’s chakra can use one Rinnegan path, which Nagato can do himself. Nagato himself, along with Conan, who helps Nagato, and the six bodies who receive chakra from Nagato, refer to themselves as Pain. Nagato and Conan are the founders of the Akatsuki organization.
Nagato, who had Rinnegan since he was a child, accidentally awakened it when his emotions were triggered and killed others in just a few seconds. However, even though Nagato could not control his power, the power of the Rinnegan that he accidentally awakened was more than enough to fight all his enemies. That’s why Nagato was never defeated except by Naruto. If Sasuke Uchiha is the most powerful Rinnegan user, Nagato Uzumaki is the shinobi who can use the Rinnegan’s ability to the fullest. Because Nagato obtained Rinnegan since he was a child, he slowly trained continuously until he fully mastered it. It can be said that Rinnegan is Nagato’s basic power, while Sasuke’s basic power is Sharingan.
