In CMLL Heavy Metal was an upper card tecnico. He was usually allied with his brothers Negro Casas and Felino. As with other CMLL upper tecnicos, he didn't really have any ongoing feuds of his own, but just opposed the various forces of evil on a weekly basis.
Heavy arrived in CMLL after spending years in AAA. Sources say Metal was angered about Konnan being allowed to return to the promotion, feeling he (and others) had worked hard to rebuild the promotion after Konnan had left the company and raided it for talent. When Antonio Pena made it clear Konnan would be a part of AAA, Metal left, jumping first to IWRG and then to CMLL.
Metal showed up in CMLL as a very muscular wrestler, which seemed to diminish his work in the ring. He cut his weight down and looked like a much improved wrestler.
