Desmond Spellman is a powerful warlock and the main antagonist of the 1998 direct-to-video film Casper Meets Wendy.
He was portrayed by George Hamilton.
He is an evil warlock with mastery over both sorcery and alchemy who has enjoyed a luxurious and wealthy lifestyle for a very long and undetermined number of years and settling down in his mansion, while remained the most feared and greatest conjuror in the world, and he commands the Oracle of the Mirror, an ancient mystical spirit in a antique mirror that is now in Spellman's possession.
One morning, the Oracle of the Mirror informs him that now his only goal is to destroy Wendy, the Good Little Witch, since he discovers that she will be the most powerful witch on Earth and he will have no choice but to forfeit his rank if he does not act immediately, so he decides to kill her at any cost. The Oracle tells him that the only secure way to exterminate a witch is sending her to a strange and dreaded portal-like netherworld called the Mystic Abyss, and according to the Oracle, everything that enters it disappears forever and never return once they crossed over the threshold of the gateway.
On the run from her nemesis, Wendy discovers and befriends Casper, the Friendly Ghost. Later on, she tells him that she is being chased by Desmond because of her powers and begs him not to tell anyone about this. However, back to his house, he accidentally tells his uncles that the witches can't use their power because of Desmond, so the Ghostly Trio attack the witches, but Wendy saves them.
However, after fleeing again, they are trapped by Desmond and his henchmen. Desmond casts his magic to summon the doorway to the Mystic Abyss as he soon attempts to get rid of Wendy by throwing her in, but Casper dives in to save her. Her aunts try to fight Desmond but they were not powerful enough. As he tries to send them along with Casper and Wendy, before the abyss closes itself, a three eyed creature pops up and scares him, causing him fall into the abyss instead. The creature turns out to be the Ghostly Trio, whom combined together to defeat Desmond. Then, the Ghostly Trio and Wendy's aunts save Casper and Wendy from their doom and since Desmond fell into the Mystic Abyss, he was gone forever, presumably either being destroyed by being zapped by the portal, shrunk until he disappears, or was sent to hell which the Mystic Abyss really is.
- Desmond is the only main villain in the Casper films that does not have any vendetta or motivation against Casper and the Ghostly Trio, with his goal being to destroy Wendy and her aunts, in order to still remain the greatest witch of all, whereas in one film has a villain that wants to throw Casper and the Trio out of there home to collect the treasure, as well as stealing Casper's capsule to be human herself once she turns into a ghost, and in another film has a villain who wants to banished Casper and the Trio for skipping training.
- While Desmond may not have any vendetta against the ghosts, their interference with his plan to destroy the witches does make them an enemy to him.
