Misterio began his professional wrestling career in 1976 and continued to compete until 2009. He did return for a few more bouts, the latest of which took place in 2023.

In 1990, Misterio competed in a tournament at WCW Starrcade. He and Konnan defeated Norman Smiley and Chris Adams in the quarterfinals before losing to Scott and Rick Steiner in the semifinals.

According to Thomas Lawson of SE Scoops, Misterio founded a gym in 1987 with professional wrestlers Negro Casas and Super Astro. He also trained superstars like as Konnan, Psicosis, and Mysterio.

According to Ben Flanagan of al.com, Misterio was inducted into the Tijuana Sports Hall of Fame in 2006.

Dave Meltzer: "So sorry to hear about the death of the original Rey Misterio (Sr.), Miguel Lopez, at 66, the uncle of the WWE star. In his heyday he was almost like Tijuana's version of Jerry Lawler in Memphis. As a trainer, his track record matches the best, his nephew, the original…"

Prayers, condolences, and thoughts are with the family during this difficult time. The Mysterio family is also still mourning the death of Roberto Gutierrez, Rey Mysterio Jr.'s father and Dominik's grandpa, who died on November 17 at the age of 76.
