In Mexico, Melchor is perhaps best known for his tenure with CMLL, where he is a former five time Mexican National Heavyweight Champion.
A popular competitor throughout the 1970s and 80s as both a técnico and rudo, his real name was not a matter of public record (as is often the case with masked wrestlers in Mexico) until the 29th of July 1977, when he lost his mask in a match against Mil Mascaras at Arena Mexico.
He also had a stint with All Japan Pro Wrestling, where he took his rivalry with Mil Máscaras, competing against him at AJPW Summer Action Series II 1978.
[7] On July 29, 1977, he lost his mask in a bout against Mil Mascaras at Arena Mexico, after which he revealed his real name and soon was to be known as "Danny" Ortiz within the promotion.
As a técnico (fan favourite) he competed unmasked under the ring name "Halcon Ortiz".
