La Máscara is a midcard tecnico in CMLL. As of July 2006, he's the current Mexican National Welterweight Champion, with all of this defenses so far having come away from Mexico City. (He's since lost the belt to Sangre Azteca.) La Máscara is the sone of Brazo de Oro, and the promotion acknowledges the relationship.
La Máscara has been pushed strongly since changing to that gimmick (from Brazo de Oro Jr.), with some thought that it might be due to his family connections. His work has appeared to catch up with his push this year, and he's a solid high flier.
