Long time Monterrey based wrestler. Brought into CMLL in August 2009 as an opening match tecnico. His brother, Trueno has long been in the same role, but they've yet to team up or acknowledge the relationship in CMLL. In late 2010, the relationship between Trueno and Delta was acknowledged, as Delta surpassed his brother's level in CMLL. Delta & Diamante rose fast in CMLL in 2010, winning the Arena Coliseo Tag Tournament but not the championships.
Delta won a poll at the end of 2010 to replace Mascara Dorada as Stuka & Metro's teammate. The team was Mexican National Trios Champions at the time Dorada left the group, and CMLL wavered back and forth on if the winner of the poll would automatically become the champion. Delta's team met the winners of the Mexican National Trios Contenders Tournament, 2010 in the first 'defense'. Delta's trio did not bring the belts to the ring, did not appear to be champions, and lost the match, so Delta is not credited with a championship reign.
