In at least one universe's Oz, the Crooked Man created the magical Powder of Life. (PROSE: The Crew of the Copper-Colored Cupids in Oz)
Behind the scenes
“The Crooked Man” originates in the popular English rhyme There Was a Crooked Man, and many realisations of the character have been used in broader narrative media since, including Barnaby in the 1903 operetta Babes in Toyland and “the Crooked Magician”, Doctor Pipt, who was first mentioned in L. Frank Baum's Oz books in 1904's The Marvelous Land of Oz as an unnamed background figure responsible for the Powder of Life, later appearing in person and being named as Pipt in The Patchwork Girl of Oz. All three of these variants of the basic figure are now in the public domain.
