Demonic Statue of the Outer Path

The Demonic Statue is a giant, earthen-coloured humanoid entity with a mummified appearance, a body shaped similar to a robe, and a number of spike-like protrusions on its back. It towers over even the tailed beasts, with Gyūki only reaching its chin, and Akimichi clan members at their maximum size; it is nearly half the size of a tall mountain. The statue has nine eyes the size of an adult man, which usually remain closed. When opened, the eyes are featureless and white, but one gains a light blue iris each time a tailed beast is sealed inside the statue. After being summoned by Madara, the statue initially wore a blindfold that completely covered its eyes, but the blindfold gained holes for each of its eyes sometime after Nagato's encounter with Hanzō. The statue's wrists and ankles are usually bound by shackles and it bites down on a scroll, which is held in place by two ropes extending from beneath its blindfold on either side of its head. When summoned into battle, the statue breaks free of its restraints, causing the scroll in its mouth to hang from the left rope like an earring. During its transformation into the Ten-Tails, the statue's mouth widens and the protrusions on its back extend and warp in shape.

At the conclusion of their battle with the Ten-Tails, the brothers Hagoromo and Hamura Ōtsutsuki used Six Paths — Chibaku Tensei to transform the beast into the core of the newly-formed moon, while also extracting the beast's chakra and sealing it in Hagoromo. Hamura then took leadership of the Ōtsutsuki clan and migrated to the moon in order to guard the Ten-Tails' husk. A millenium later, Madara Uchiha awakened the Rinnegan, which allowed him to break the seal and summon the husk out of the moon. Madara used the husk, which he named the Demonic Statue of the Outer Path, as a catalyst to cultivate Hashirama Senju's cells, producing a non-sentient clone of Hashirama housed within a gigantic flowering tree. He was then able to live beyond his natural lifespan by attaching himself to the tree, which served as a means of life support by continuously supplying him with the Demonic Statue's chakra. Madara believed that the combination of the Demonic Statue and Hashirama's cells caused artificial humans to grow on the tree's branches, but in actuality, Black Zetsu was secretly removing them from inside the statue, where they had been stored for centuries. At some point, Madara transplanted his Rinnegan into Nagato without the boy's knowledge, making him the only other person capable of summoning the statue. When Obito Uchiha later agreed to continue Madara's Eye of the Moon Plan following his death, the elderly Uchiha explained that he must revive the Ten-Tails by sealing the nine tailed beasts inside the statue. Madara then disconnected himself from the statue's chakra, and with his dying breath, told the young Uchiha that he was to act using his name until the time of his resurrection. In the anime, during the Third Shinobi World War, Nagato unconsciously summoned the Demonic Statue in a fit of rage when his friends were injured in an enemy ambush, though he quickly regained his senses and fell unconscious, at which point the statue disappeared. An enraged and grief-fuelled Nagato later summoned the Demonic Statue after being forced to kill Yahiko by Hanzō. The statue pierced Nagato's back with black receivers and drained his life force, leaving him permanently emaciated while also granting him a means of killing Hanzō's men, with only Hanzō himself escaping the altercation alive. As Pain, Nagato would summon the Demonic Statue whenever a jinchūriki or tailed beast was captured by Akatsuki so that the organisation's members could seal the beast inside it.
