Jareth is the main antagonist of the 1986 Jim Henson film "Labyrinth". He is the human king of the goblins. Of course, his evil isn't intentional. He is just trying to grant wishes, even if they are not really intended. He takes away the heroine Sarah Williams' infant half-brother Toby, away from her as she wishes exaggeratingly. Later, he tries to keep her to himself because of this, and he has her try to solve the Labyrinth (while adding obstacles in the process). David Bowie played him.
