Mōryō

Mouryō is a large, dark demon that appeared in the first movie of the Naruto Shippuden series viz: Naruto: Shippūden the Movie. Mouryō 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, Mouryō 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 Mouryō'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. Mouryō then tried to absorb Shion, but she was saved by Naruto. He was then killed by the Naruto-Shion Super Chakra Rasengan.

Trivia

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