In 1995, La Parka would make an appearance for Extreme Championship Wrestling (ECW), teaming with Psicosis, losing a tag team match against Konnan and Rey Misterio Jr..
In mid-1996, La Parka began appearing on WCW's weekly television shows and pay-per-views. La Parka often wrestled against Juventud Guerrera or Super Caló and often teamed with Psicosis. Due to La Parka's more comedic style he stood out from the rest of the Luchadores, who were generally high fliers. He was nicknamed "the chairman of WCW" due to the fact that he often carried a chair to the ring, played air guitar on it during his entrances and generally used it both in matches and in post match celebrations. At one point he and Psychosis were managed by Sonny Onoo, although the team failed to achieve much success as a unit. He later dropped Onoo as a manager and begin to feud with Psychosis and Disco Inferno. While La Parka often wrestled on WCW's Monday Nitro show, his pay-per-view appearances were rare. On July 13, he teamed with Psychosis and Villano IV on the undercard of WCW's Bash at the Beach pay-per-view, losing to Héctor Garza, Juventud Guerrera and Lizmark Jr.. He also wrestled at SuperBrawl VIII, losing to Disco Inferno.
One night in a match against Randy Savage, La Parka suddenly executed Diamond Dallas Page's finisher, the Diamond Cutter on Savage and gained the pinfall. After the match "La Parka" unmasked to show that it was Savage's rival Diamond Dallas Page under the mask, using the ruse to get back at Savage. A couple of weeks later, Savage wrestled against the real La Parka defeating him to gain a small measure of revenge. In October 1998, La Parka became part of Eddie Guerrero's Latino World Order (LWO), a group that also included Psychosis, Juventud Guerrera, Villano IV, Villano V, El Dandy, Silver King, Héctor Garza, Damián, and a reluctant Rey Mysterio Jr.. The group feuded mainly with Konnan and Perry Saturn. In January 1999, Guerrero was injured and the LWO group was subsequently abandoned.
In late 1999, he teamed with Kaz Hayashi, a Japanese wrestler who used a "Comedic voiceover" gimmick and referred to La Parka as "Skull Captain". La Parka left WCW in 2000.
