Macaque (short for Six-Eared Macaque) is a demon and a former friend of the Monkey King.

Over five hundred years after the Demon Bull King's imprisonment, Macaque met Monkey King's successor, MK, who wanted Macaque to train him so he could get better. Macaque accepted and slowly corrupted MK as he trained him until he stole his powers, getting the same abilities as Monkey King's. Eventually, he engaged in a battle with Monkey King and was later defeated by MK.
