Rou Shan was a colossal shapeshifting yokai/yaoguai who was considered the bringer of Yamamura and the lead general of the Yokai army. After being supposedly slain into seven pieces by former Horse Emperor Malong. The seven listed his head, his arms and torso, his intestines, his spine, his legs, his eye, and a tooth. The tooth containing a deadly poison that eventually killed Malong. The seven of his pieces continued to wreak havoc on the land during Yamamura but were eventually hunted down and subdued by Arku Khan and his Monkhu Horde. Some pieces, such as his intestines, still roam free

in the Surochi sands.
