Bimawen.

The Six-eared Macaque is a demon known for stealing faces, he took identities, pretending to be others for years on end before giving back their lives. He thought he would be doing that for eternity but eventually Heaven got fed up with his ways and captured him. Now, he only has two choices : either be executed for his crimes or become the attendant of the current Bimawen, formerly known as the fearful Monkey King. Of course he chose the second option and now he's stuck under the orders of a prideful pick tending to the celestial stables.
