Demonic Statue of the Outer Path

The is a personal summon of Nagato.

Appearance
The Demonic Statue is a giant, stone creature. When summoned it bursts from the ground, with only its upper torso and arms visible. Its back has a number of rocky protrusions. When it is first summoned by Nagato, the Statue is wearing a blindfold. During subsequent Akatsuki appearances, nine slots for its (normally closed) eyes are present in the blindfold. In these appearances its arms are also bound in shackles and it has a bit in its mouth.

Role
Nagato first summoned the Demonic Statue during his battle with Hanzō and his forces. As soon as it appears it pierced him with a number of Chakra Disruption Blades, causing Nagato to become emaciated. Nagato used it to annihilate Hanzō's men.

Years later, the statue became the means behind Akatsuki's tailed beast extraction. Nagato summons the statue and the other Akatsuki members then convene and, over a period of three days, extract the tailed beast from its jinchūriki and seal it into the statue. As the sealing nears completion, one of the eyes corresponding to the beast that is being sealed opens. When the sealing is completed, the bit falls from the Statue's mouth.

Thus far the statue has had the first seven tailed beasts sealed into it. The Nine-Tailed Demon Fox must be sealed into it last, or else the Statue will be destroyed. After Nagato's death, Madara Uchiha indicates that Nagato was just a pawn that the Demonic Statue had been synchronized with. He states he would like Sasuke Uchiha to be Nagato's replacement, but decided to wait until Sasuke was easier to manipulate. Ultimately, a hybrid entity grown from Hashirama Senju's cells and Zetsu was used to synchronize with the statue. This hyrbid grew a flower for which the statue to sit, from where it was able to transfer it's chakra via it's rods and allow the hybrid to grow numerous clones of Zetsu. These clones are to serve as the army for Madara's battle against the shinobi world.

Abilities
The Statue is able to emit dragon-like forms of energy from its mouth. When these dragons come into contact with ordinary humans, the humans' souls are ripped from their bodies, killing them. When these dragons surround a jinchūriki or a tailed beast, the tailed beast's chakra is gathered to the Statue's mouth and stored inside for future use. Nagato wanted to use these beasts to create a weapon that could destroy a country. Madara wants to reassemble them into the Ten-Tailed Beast.
