Princess Ozma

Princess Ozma (EmeraldCity_Oz) is the ruler of the Land of Oz, as well as a part-time Magical Girl (no relation to Kyubey, though).

Backstory
Before she was the Princess of Oz, Ozma grew up as a young boy named Tip in the North of Oz, in the Gillikin Country. He originally worked as a slave to Mombi, the former Wicked Witch of the North. After a series of adventures, however, Tip realized he was actually Ozma, the lost princess, hidden away by the Wizard many years ago when he was an infant. Tip then assumed his identity as Princess Ozma, and ended the wars and political squabbles that plagued her land, creating a time of relative peace where the people of Oz no longer needed to worry about dying, being able to live as long as they wished.

Magical Girl Abilities
In contrast to her girlfriend, Ozma's Magical Girl powers were not given to her by Kyubey, but rather by the Fairy Queen; as a result, she does not have a Soul Gem.

As a Magical Girl, Ozma has a silver, knee-length dress with a translucent cape, and a silver coronet around her head. Her forehead has a special symbol given to her from the Fairy Queen.

Her main weapon is a silver bow and arrow; if she charges her blast, she can create a powerful laser-like attack.

Trivia

 * In the original books, Ozma's age tended to fluctuate from writer to writer, with her being portrayed as no older than sixteen. Per the third book's mention of her and Dorothy being around the same age, Ebooks Ozma and Dorothy are both physically fifteen.
 * Likewise, Ozma's backstory, while keeping to the general outline presented in the original books, is slightly different in a few details.
 * Due to her experience with cats (Eureka, Bungle, Goro), she prefers dogs.
