ミル・マスカラス
In 1965, Santo walked out on producer Vergara over a contractual dispute, and Blue Demon suffered injuries and was thus unable to work. Vergara discovered Aaron Rodriguez, a young luchador, and offered him to star as Mil Máscaras. Máscaras was the first superhero/lucha libre personality created specifically for the movies, and he starred in 20 lucha films, including "Enigma de muerte" with John Carradine and "Mil Mascaras vs. the Aztec Mummy" with El Hijo del Santo, Blue Demon Jr., and Huracan Ramirez Jr..
