Mōryō

was a large, dark demon that appeared in Naruto: Shippūden the Movie.

Background
Mōryō tried to destroy the world and create a one thousand year kingdom. However, he was stopped and sealed away before he could so by Miroku, the high priestess of the Land of Demons.

Plot overview
However, it was later freed by Yomi. From that point on, Mōryō inhabited Yomi's body, and gave orders to his four followers whilst controlling his stone army, who were headed toward the sealing shrine to retrieve Mōryō's body. When he arrived, he went inside and met with Shion. He then confused her in order to distract her whilst he 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 mother, Miroku. However, he couldn't absorb Shion because of the bell that held her true powers.
