DMT Azul is the best known ring name of a Mexican Luchador Enmascarado, or masked professional wrestler. He is currently signed to Lucha Libre AAA Worldwide. Azul is best known for his time in Mexican professional wrestling promotion Consejo Mundial de Lucha Libre (CMLL). He originally wrestled under the ring name El Romano but in 2009 he was given a new name and mask, Metro, a ring name that had been used by at least three other CMLL wrestlers before 2009. The "Metro" ring character was sponsored by the Mexico City Metro newspaper, incorporating the newspapers logo and color scheme (red and gold) in the mask and wrestling trunks. In early 2012 he was given a new image and ring name, dropping the sponsored ring name to become Diamante Azul instead. Diamante Azul is Spanish for "Blue Diamond".
