Title: Wicked Witch of the West
Content:  The Wicked Witch of the West is a fictional character who appears in the classic children's novel The Wonderful Wizard of Oz (1900), created by American author L. Frank Baum. 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. The witch's most popular depiction was in the classic 1939 film based on Baum's novel, where she was portrayed by Margaret Hamilton. Hamilton's characterization introduced green skin and this has been continued in later literary and dramatic representations, including Gregory Maguire's revisionist Oz novel Wicked: The Life and Times of the Wicked Witch of the West (1995) and its musical stage adaptation Wicked (2003), the 2013 film Oz the Great and Powerful, and the television series Once Upon a Time and Emerald City.

Title: The Wicked Witch of Oz
Content:  The Wicked Witch of Oz is a novel by Rachel Cosgrove Payes. Written in the early 1950s but not published until four decades later, the book is a volume in the series of Oz books by L. Frank Baum and his successors. Cosgrove Payes had published her first Oz book, The Hidden Valley of Oz, in 1951 with Reilly & Lee, the publisher of the Oz series since the time of Baum. The Wicked Witch of Oz would have been the next book in the series, and was intended for publication in 1954 but Reilly & Lee cancelled the project, since the Oz books were no longer selling well. The book remained unpublished until the International Wizard of Oz Club brought out the first edition in 1993, with illustrations by Eric Shanower. The club declared it book 45 in the series. In the documentary, Oz: The American Fairyland, Payes states that she refused all requests to read her manuscript with "not 'til it's a book." The Wicked Witch of Oz is followed by The Emerald Wand of Oz, a 2005 book by Sherwood Smith which was commissioned by the Baum Family Trust.

The Wicked Witch was a middle aged, malevolent woman who conquered and tyrannized the Munchkin Country in Oz's eastern quadrant, forcing the native Munchkins to slave for her night and day. Her charmed Silver Shoes (famously changed to magic ruby slippers in the 1939 film musical) held many mysterious powers and were her most precious and prized possession. The Witch met her demise when Dorothy Gale's farmhouse landed on her after being swept into the sky by a cyclone. Her old and withered body turned to dust, leaving behind the magical shoes that were passed to Dorothy as their new owner.

The musical is told from the perspective of the witches of the Land of Oz; its plot begins before and continues after Dorothy's arrival in Oz from Kansas, and it includes several references to the 1939 film and Baum's novel. Wicked tells the story of two unlikely friends, Elphaba (the Wicked Witch of the West) who was born in Munchkinland as well as Glinda of the Upper Uplands, Gillikin County.

Kristin Chenoweth originated the role. Ariana Grande is slated to play the role in the upcoming film adaptation of the musical.

Title: The Wicked Years
Content:  The Wicked Years is a series of novels by Gregory Maguire that present a revisionist take on L. Frank Baum's The Wonderful Wizard of Oz, its 1939 film adaptation, and related books. This is a very different and cynical look at Oz as is seen in the books by L. Frank Baum or the film(s). Unlike the originals, these books are targeted limitedly for mature readers, meaning they are not intended for children.

Many of the protagonists in the Wizard of Oz are presented either as antagonists or neutral. The first book in the series, Wicked, was adapted into a successful musical of the same name.
