Goblin King

The Goblin King is the ruler of the goblins and the father of Fairy Princess Willow. His magic scepter was the object of Krudsky's attempt at theft.

Power and abilities
He has virtually unlimited magical power, almost all through his scepter.

History
Krudsky got the scepter from him in a deal for Fairy Princess Willow and captured Fred, Daphne and Velma. He turned Velma into a werewolf, Fred into a vampire and Daphne into a witch. When the Goblin King regained his power he turned them back and erased the gang's memories of the night, except from Shaggy and Scooby.
