Ozma, the fair young dark-haired empress of Oz, stays perpetually young and is a powerful (but kindly) sorceress. She was stolen from the cradle and enchanted by old Mombi, a witch, in to the form of Tip, a mischievous young boy (everyone says the Oz books are so wholesome, but look at all this gender swappin' and unchristian magick! ;)), in order to prevent her from taking her rightful place in the emerald city, but in the end was transformed back to her true self by Glinda the Good, and took over from the humbug Wizard of Oz, who stepped down to become her advisor and learn some real magic. That's not the only time she was transformed - she was once kidnapped and turned in to a golden peach pit before being rescued by her friends. Seems everyone has an identity crisis sooner or later in Oz.
