Alejandro Cruz Ortiz (May 3, 1921 – March 8, 2007) was a Mexican Luchador (professional wrestler), known worldwide as Black Shadow (Spanish: Sombras).

He was nicknamed El Hombre de Goma, translated as The Rubber Man, due to his elasticity and flexibility in the ring.

After making his debut Cruz realized that he needed to perform regularly in order to improve, thus he decided to move to Monterrey which at the time was one of the main cities for wrestling in Mexico.

In the mid-1950s Los Hermanos Shadow began a decade long rivalry with the top Rudo (villain) team of El Santo and Gory Guerrero, known as "La Pareja Atómica".

[1] The match was one of the main reasons wrestling promoter Salvador Lutteroth started to build Arena Mexico as so many people had been unable to get tickets for the show.

His innovative, high-flying style that incorporated moves off the top rope was something not many wrestlers used at the time and ensured that he worked in the main event throughout the 1950s and 1960s.
