Kalabar, also spelled Calabar, is a warlock and former boyfriend of Gwen. He is the main antagonist of the first film. Prior to the film, Kalabar is the Mayor of Halloweentown. He is a racist (he hates humans) and dislikes the fact that Gwen left him for a human, William, yet the Cromwell magic remains as powerful as ever. At first, he was in the form of a creature who's afraid of sunlight, but reveals his true identity when he tries to convince the citizens of Halloweentown to join him in order to retake what's rightfully theirs, i.e. the mortal world by bringing them back as rulers of the human race. He dies at the end of Halloweentown when the Cromwell family members join together to vanquish him.
His son Kal is the primary villain in Part II. He appears in Halloweentown II during several flashbacks to the previous film. In the first film his name is actually spelled as "Calabar", not "Kalabar". His name is also spelled "Calabar" in the Halloweentown II: Kalabar's Revenge closing credits.
Kalabar was portrayed by Robin Thomas, in the first film: Halloweentown which was released in 1998.
- Despite his feelings for Gwen, he had a son with something else.
- The reason Kalabar hates humans may be do to Gwen choosing to marry one instead of him.
- He obviously pronounces Sophie's name wrong by calling her "Soapy".
