Personality:While the Goblin King appears to be a cruel and terrifying monster as many monsters are shown to be quite scared of him, even if they hear his name said out loud, he is actually quite the opposite. The Goblin King is kind and caring and truly loves his daughter, as he was willing to give up his magic scepter in order to get her back safely. However, he is shown to be firm and strict as he held his daughter responsible for all the trouble that had occurred on Halloween and grounded her for a year.
He also doesn't tolerate those who he sees to be an enemy as he send Shaggy Rogers and Scooby-Doo to the tower dungeon when they attempted to steal the scepter or when he decided to punish Krudsky for all the troubles he caused. However, he later changes his opinion of Scooby and Shaggy when he witnessed their bravery in stopping Krydsky, and thus allowed them to keep their memories of everything that had happened. The Goblin King is shown to be cautious and careful when regarding his magic as he tried to warn Krudsky that he wouldn't be able to handle the power of the specter. The Goblin King is also shown to be care for his friends as he brought Jack O'Lantern back to life by relighting his flame.
Powers and abilities: Flight: He has wings. Magic scepter: He has virtually unlimited magical power, almost all through his scepter.
History: Krudsky got the scepter from him in a deal for the return of Fairy Princess Willow. When the Goblin King regained his power he turned them back to normal, and erased the gang's memories of the night, except from Shaggy Rogers and Scooby-Doo.
