Debuted in CMLL in 2015, briefly wrestling as in the mini luchador. Quietly moved to the main division, still mostly the same preliminary match. Defeated Espiritu Negro for his mask on New Year's Day in the first (only) meaningful match in his career. Announced he was changing his name to Diamond on January 15th, complete with a Santo-knockoff outfit. Debuted under the new name on January 19th.
