Mōryō

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

From that point on, Mouryō inhabited Yomi's body and give orders to his four followers while he controlled his stone army heading towards the sealing shrine to retrieve his own body. When he arrived he went inside and met up with Shion. By twisting her he retrieved his demon body and began a fight with Naruto and almost absorbed Shion who was saved from inside him by Naruto. He was killed by Naruto-Shion Super Chakra Rasengan.

Trivia

 * Mouryō did absorb Shion's mom, Miroku, somewhere in the story, but he couldn't absorb Shion because of the bell that held her true powers.
