Willi Ninja, American dancer and choreographer (b. 1961)
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.

The film also documents the origins of "voguing," a dance style in which competing ball-walkers freeze and 'pose' in glamorous positions (as if being photographed for the cover of Vogue magazine).

In 1989, Ninja starred in the music video for Malcolm McLaren's song "Deep in Vogue," which sampled the then-unfinished movie and brought Ninja's style to the mainstream. One year after this, Madonna released her number one song "Vogue," bringing further attention to the dancing style.
