Mōryō

is a large, dark demon that appeared in the first movie of the Naruto Shippuden series viz: Naruto: Shippūden the Movie. Mōryō tried to destroy the world and create a one-thousand year kingdom. He was stopped and sealed away by Miroku, the high priest of the Land of Demons. However, it was later freed by Yomi.

From that point on, Mōryō inhabited Yomi's body and gave orders to his four followers while controlling his stone army (who were headed toward the sealing shrine to retrieve Mōryō's body). When he arrived, he went inside and met up with Shion. He then confused her and retrieved his demon body. Naruto then arrived and they began to fight. Mōryō then tried to absorb Shion, but she was saved by Naruto. He was then killed by Naruto and Shion's Super Chakra Rasengan.

Trivia

 * Mōryō absorbed Shion's mom, Miroku. However, he couldn't absorb Shion because of the bell that held her true powers.

At the end of the battle, when Naruto jumps into the demon pit, while he is falling the dragon stabs him through the middle of his stomach. Naruto is presumed dead.
