Kalabar

Kalabar is a warlock and former boyfriend of Gwen. He is the Mayor of Halloweentown. He is extreamly hateful of humans going so far as to try and get the creatures of Halloweentown to join him in destroying humans to take over the Mortal World, but ends up getting vanquished by Aggie, Gwen, Marnie, Sophie, and Dylan at the end of Halloweentown. He dislikes that Gwen married a human. He mostly appears in the form of a black creature.

He has one son, named Kal.
