Fairy Princess Willow

Fairy Princess Willow is the leading female protagonist of Scooby-Doo and the Goblin King.

Scooby-Doo and the Goblin King
Princess Willow is the daughter of the powerful Goblin King. She is rebellious and loves to explore, and when we first see her, Willow plays pranks on the wicked magician Krudsky, which leads to her capture. Krudsky steals her fairy powers and she remains his prisoner throughout virtually the whole film. Willow is finally released, but the Goblin King scolds and grounds her for sneaking out and for her selfishness but admits he's glad to have her back. In the end, Willow brings Jack-O-Lantern back to life after a battle and blesses Shaggy and Scooby-Doo with the magic of the fairies.

Trivia

 * Fairy Princess Willow is voiced by Hayden Panettiere.
 * Fairy Princess Willow has similarities to Ariel in The Little Mermaid because both of them refuse to let anyone control their lives, are free-spirited, and disobey their fathers, but Willow is completely opposite of who Ariel is. Ariel wants to leave her home and explore the human world because she feels restricted by palace life but shows her father that he cares by saving his kingdom. Willow, on the other hand, sneaks out of the castle to be free to do what she wants and uses excuses to get her way, never showing any sincerity or true love to her father. Simply put, Willow is what Ariel would have become if she exchanged the love of her family for getting her own way.
