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 Monterrey he befriended another young wrestler trying to break into the business , Blue Demon . The two struck up a friendship and soon after began teaming together on a regular basis . After working under his real name for a while , Cruz decided that he needed a different image . Cruz came up with the ring persona " Black Shadow " and a black mask with white trim around the eye , mouth and nose openings . The new image was a hit and masked duo of Blue Demon and Black Shadow became known as " Los Hermanos Shadow " ( Spanish for " the shadow brothers " ) despite not being related .
