Carl Nickerson (The Mighty Leviticus) is a Canadian sideshow entertainer and entrepreneur. Born in Montréal, Québec, Nickerson spent much of his life based in Winnipeg, Manitoba. As "The Illustrated Strongman, The Mighty Leviticus", Nickerson performs feats of strength and pain resistance as a throwback-style circus strongman. He performed in the sideshow tent at the 1930s-era revival Carnivàle Lune Bleue in 2008, 2009, and 2010. Afterward, Nickerson and two of his Carnivàle Lune Bleue colleagues (BonBon Bombay and István Betyár) founded the Blue Mushroom Sirkus Psyshow, a Montréal-based circus/variety troupe. In 2017, Nickerson founded Production Qu'est-ce que Phoque, a film production company focused on creating documentaries about the circus life.
