Krudsky

"Three magic words: No. Dogs. Allowed."

"By the fearful powers of Halloween night, give to me this fairy's light!"

"This will teach you to meddle in the affairs of magicians!"

The Amazing Krudsky, or Krudsky for short, is the main antagonist of Scooby-Doo and the Goblin King. He is a selfish and evil magician who will do anything to get a quick buck and supreme power, no matter how vile a deed it is.

Scooby-Doo and the Goblin King
When Scooby-Doo and the group arrive in a Halloween carnival, Krudsky lets them come and see his show but won't allow Scooby to come. Shaggy and Scooby deliberately expose him as a fraud on his magic show, and with that, Krudsky plots a rather nasty revenge. Searching for a victory, he discovers in his spellbook the Goblin Scepter, which belongs to the mighty Goblin King. The mischievous Fairy Princess Willow flutters in and Krudsky abducts her and steals her magic powers, which turns him into a magician himself. The eccentric Mr. Gibbles tries to stop him, but the slimy sorcerer turns him into a rabbit and makes a deal with the Goblin King that he'll exchange Willow for the Goblin Scepter. Krudsky finally arrives and takes the scepter, which turns him into a ghastly goblin. He betrays the Goblin King and turns him into a goose. As the new king, Krudsky unleashes his power on the Mystery, Inc. gang, turning Fred, Daphne, and Velma into a vampire, a witch, and a werewolf. Luckily, Scooby-Doo and Shaggy arrive, steal the Goblin Scepter, and neutralizes Krudsky's powers with it, freeing the inhabitants. Before Krudsky can get even with the brave twosome, the Goblin King turns against him and imprisons him in a glowing ball. He cries out "''I WANT MY MOMMY!" ''as the Goblin King takes him into the Spirit World.

Trivia

 * Krudsky is voiced by Wayne Knight.
 * His personality is reminiscent of Stromboli because of his desire for money and power and Turbo/King Candy because he appears to be silly but hides a cruel heart and turns into a monster.
 * Krudsky's defeat is like Tortoise John in Rango because the evil creature he hired turns on him in the end.
