The Wizard of Oz books featured a magic back-and-forth tranny:
While still an infant, Ozma, the baby daughter of the former King Pastoria of Oz, was given to the witch Mombi of the North by the Wizard of Oz. Mombi transformed Ozma into a boy and called him "Tip" (short for Tippetarius) in order to prevent the rightful ruler of Oz from ascending to the throne. Thus, Ozma spent her entire childhood with Mombi in the form of the boy Tip, and had no memory of ever having been a girl. During this time, Tip had managed to create Jack Pumpkinhead who was brought to life by Mombi's Powder of Life. In The Marvelous Land of Oz, Glinda the Good Sorceress discovered what had happened and forced Mombi to turn Tip back into Ozma; ever since then, the Princess has possessed the Throne of Oz (although many realms within Oz remained unaware of her authority).
