William Roscoe Leake (April 12, 1961 – September 2, 2006), better known as Willi Ninja, was an American dancer and choreographer best known for his appearance in the documentary film Paris Is Burning. Ninja, a gay man known as the godfather of voguing, was a fixture of ball culture at Harlem's drag balls who took inspiration from sources as far-flung as Fred Astaire and the world of haute couture to develop a unique style of dance and movement. He caught the attention of Paris Is Burning director Jennie Livingston, who featured Ninja prominently in the film. The film, both a critical and box office success, served as a springboard for Ninja. He parlayed his appearance into performances with a number of dance troupes and choreography gigs.
