Reincarnation

is a process through which the chakra of a deceased individual is reborn in a new living vessel. The living vessel is also referred to as a reincarnation.

Overview


For centuries after their deaths, the chakras of the sons of the Sage of the Six Paths, Indra and Asura Ōtsutsuki, would continue to be reincarnated into their descendants. During the Warring States Period, their chakras would be reborn into Madara Uchiha and Hashirama Senju, who would continue the brothers' struggle until their own deaths. Prior to Madara's death, Black Zetsu would manipulate him into becoming the first reincarnation to successfully merge Indra's and Asura's chakras, and this would lead to the awakening of the Rinnegan.

After Madara's death, the chakra of Indra and Asura would be reborn into Sasuke Uchiha of the Uchiha clan, and Naruto Uzumaki — a descendant of Asura through the Uzumaki clan, respectively. As the first reincarnations to have been born into an era of relative peace, the two would maintain a rather civil rivalry until Sasuke would fall victim to his clan's Curse of Hatred.

The reincarnation cycle will not start again until both of the current reincarnations have passed away; the brothers would not reincarnate until Madara's death, which would occur decades after Hashirama's.

The chakras of Indra and Asura change chakra signatures with each reincarnation. Although Hashirama and Naruto are both Asura's reincarnations, Madara, a sensor type, was able to differentiate their chakras. However, the chakra pathways do not appear to change, or at the very least, contain similarities. Whilst using the Byakugan, Kaguya Ōtsutsuki was able to note that Naruto and Sasuke were the reincarnations of her grandsons.

 * Reincarnation Ninjutsu are techniques that usually require or accomplish the transfer of life force between people.
 * Without use of special jutsu, Obito Uchiha has shown the ability to transmigrate and enter living vessels to bestow them the power of his eyes. This is first seen in Road to Ninja: Naruto the Movie, when a phantom-like "Masked Man" possesses Menma and gives him the Sharingan eyes. On the side of the Allied Shinobi Forces, after his death, Obito's spirit returns from the Pure Land and possesses Kakashi Hatake to awaken the Mangekyō Sharingan in both of his eyes.

Trivia

 * In the official subs for episode 421 of the Naruto: Shippūden, Hagoromo stated that the first generation of his sons' reincarnates was that of Madara and Hashirama. However, in the manga, it was stated there were numerous other reincarnates before them.
