Wicked is the prequel to The Wizard of Oz, telling the backstory of the Wicked Witch of the West, Elphaba, and her complicated relationship with Glinda, the Good Witch. While The Wizard of Oz portrays Elphaba as the villain, Wicked reimagines her character, providing deeper motivations and challenging perceptions of good versus evil. Both works are connected through the shared world of Oz, but Wicked offers a new perspective on events that unfold in The Wizard of Oz.
