Diamante Azul

Diamante Azul (2012–2021) On February 28, 2012, at a non-televised show in Arena Coliseo, Metro was repackaged under the ring name "Diamante Azul" ("Blue Diamond"), complete with a blue mask, trunks and a cape, which all closely resembled the mask and ring gear of lucha libre legend Blue Demon and his successor, Blue Demon Jr. He made his televised debut at Homenaje a Dos Leyendas on March 2, teaming with Marco Corleone and La Máscara to defeat Bucanero, Último Guerrero and Volador Jr. According to him, the design of his mask and ring gear was his own original idea. On May 1, Azul unsuccessfully challenged Dragón Rojo Jr. and Guerrero for the CMLL World Tag Team Championship with Blue Panther, but won the title with Atlantis on August 3. Later that month, he participated in the Universal Championship, defeating Pólvora in the first round before losing to Hiroshi Tanahashi in the quarter-finals.
