[1] Tinieblas began as a body builder and stunt man who was spotted by luchadores Black Shadow and Dory Dixon.

In 1968, "Lucha Libre" magazine editor Valente Pérez, came up with the idea of a character that would act as a rival for luchador Mil Mascaras.

In 1971, he starred as a member of a squadron of masked superheroes in the film '"Los Campeones Justicieros"' (The Champions of Justice).

However, his character remains popular with young lucha libre fans, primarily due to his appearance in comic books and films.

The 2D wrestling arcade game Saturday Night Slam Masters released by Japanese game company Capcom in 1993 featured a final boss character called "El Escorpión" (The Scorpion), whose appearance was inspired by Tinieblas.
