Harlin the Malevolent

From King's Quest Omnipedia

Harlin the Malevolent was an evil wizard of Serenia. He lived in a castle in a land somewhere north of the continent of Serenia in the northern Sea.

A barbarbian known simply as the Wanderer defeated him, and saved Princess Priscilla from his grasp. He had not been destroyed however, and hoped he could reverse his defeat. He believed if he used his magic to turn back time he could prevent himself from being defeated a second time. His plan failed as a new wanderer used a spell to turn into a cat, and ate him while he was in a bird form for the second time.
