In the mid-1980's, Guerrero wrestled for World Championship Wrestling (WCW) as the masked Lazer-Tron. Guerrero teamed with Jimmy Valiant and feuded with the New Breed. Guerrero teamed with Manny Fernandez as "The Latin Connection" until Fernandez turned on him to join Rick Rude and Paul Jones. In the late 1980's, Guerrero wrestled in the American Wrestling Association, winning the AWA World Tag Team Championship with Dr. D.
In 1990, Guerrero appeared in the World Wrestling Federation at Survivor Series, performing under the name The Gobbledy Gooker and wearing a turkey costume. The Gobbledy Gooker "hatched" from an oversized egg, which had been on display at WWF events for months prior to Survivor Series, and was heavily hyped on television. However, crowd reaction to the gimmick was extremely negative, with fans loudly booing as the costumed Guerrero danced in the ring with announcer "Mean" Gene Okerlund. The character made a handful of appearances in taped promos following Survivor Series, but was soon dropped from television.
Guerrero appeared with Extreme Championship Wrestling (ECW) in 1995, unsuccessfully challenging 2 Cold Scorpio for the ECW Television Championship at Return of The Funker.
Guerrero appeared in World Championship Wrestling in 1997 to confront his brother Eddie about his on-screen behavior. He left the promotion after losing to his brother in a singles match on an episode of WCW Saturday Night.
The Gobbledy Gooker was revived for the WWF's WrestleMania X-Seven to participate in the "Gimmick Battle Royal", an otherwise normal battle royal that was populated entirely by older, mostly retired wrestlers with outlandish gimmicks as well as oddball one-offs like the Gooker. Though the costume was very different from the original, Héctor Guerrero again wore the costume, being the second person eliminated in the match.
