Wicked Witch of the West
The Wicked Witch of the West is a fictional character created by American author L. Frank Baum as the antagonist in his classic children's novel "The Wonderful Wizard of Oz" (1900). In Baum's subsequent "Oz" novels, it is the Nome King who is the principal villain; the Wicked Witch of the West is rarely even referred to again after her death in the first book.
