Villano IV

In 1983 Tomas Mendoza was finally given the mask and the name of his brothers and became Villano IV.[2] He immediately began teaming with his brothers, especially Villano I and Villano V, and engaged in a heated and very popular feud with the trios team of Los Brazos (Brazo de Plata, Brazo de Oro. and El Brazo). On October 21, 1988, Villano I, IV, and V defeated Los Brazos in a Lucha de Apuesta, Mask Vs Mask match and thus unmasked Los Brazos.[5] Over the years Villano IV and his brothers have worked for Universal Wrestling Association (UWA), AAA and Consejo Mundial de Lucha Libre (CMLL) and with shorter runs with International Wrestling Revolution Group (IWRG) and World Wrestling Association holding tag team and Trios titles in all federations.[6]

Villano IV and V began working for World Championship Wrestling (WCW) as part of the influx of luchadors in 1996. Villano IV made his debut at the 1996 World War 3 event as part of the Three Ring, 60 man battle royal.[7] Subsequently, Los Villanos worked mainly the weekend shows such as WCW World Wide and WCW Saturday Night.[8] The brothers played the role of a heel and would occasionally cheat by switching places while the referee was distracted (all Villanos wore identical attire, aside from their Roman numeral distinctions). Los Villanos made a couple of appearances on WCW's main shows and PPVs such as Villano IV teaming with Konnan and La Parka to defeat Juventud Guerrera, Ciclope, and Super Calo at SuperBrawl VII.[9] They also worked an eight-man tag match at Clash of the Champions XXXV, alongside Psychosis and Silver King against Juventud Guerrera, Super Calo, Héctor Garza and Lizmark Jr.[10] Villano IV also wrestled in WCW, unmasked, under the ring name "Ray Mendoza Jr."[3] (in honor of his father), many years before his brother Villano V began using the Mexico.

Following their stint in WCW Los Villanos returned full-time to Mexico where they began working for Consejo Mundial de Lucha Libre (CMLL). Villano IV and V assisted their brother in the build-up of a storyline between Villano III and Atlantis, a storyline that reached back to 1999, while Villano IV and V were still working for WCW. The two brothers were in the corner of Villano III as he put his mask on the line against Atlantis in a Lucha de Apuesta at the 2000 Jucio Final final show. On the night Atlantis defeated and unmasked Villano III, the first Villano to be unmasked in the ring.[11] Over the following years Los Villanos worked both for CMLL and made appearances on the Mexican Independent circuit. In 2008 Villano IV acted as the cornerman for his older brother Villano V as he began a feud with CMLL luchador Blue Panther. Villano IV was the cornerman for V's biggest Apuesta win as he defeated and unmasked Blue Panther as part of the CMLL 75th Anniversary Show.[12] He was also heavily involved in V's storyline with Último Guerrero in the early 2009, and watched as Villano V was unmasked by Guerrero after an Apuesta match at the 2009 Homenaje a Dos Leyendas.[13] This left Villano IV as the only masked Villano alive. While Villano V works regularly for CMLL both Villano III and Villano IV take more independent bookings. On March 12, 2013, AAA announced that Villano IV would be returning to the promotion five days later at Rey de Reyes. This would mark his first appearance for AAA since 1996.[14] On March 16, 2013, he teamed up with older brother Ray Mendoza Jr. to compete in a Ruleta de la Muerte, losers advance tag team tournament to commemorate the retirement of Ray Mendoza Jr. The duo lost to Mil Máscaras and El Mesias in the first round and lost to El Texano Jr. and Super Nova in the second round, qualifying them for the finals where the losing team would be forced to either unmask (Villano IV) or have their hair shaved off (Mendoza Jr.). The team faced, and defeated, the team of Hijo de Pirata Morgan and Cassandro which meant Hijo de Pirata Morgan had to unmask and reveal his birthname, Antheus Ortiz Chávez, while Cassandro had all his hair shaved off as is traditional with Luchas de Apuestas losses.[15] The following day, Villano IV returned to AAA to take part in the 2013 Rey de Reyes tournament. He was the last man eliminated by L.A. Park in his six-way semifinal match, which also included Chessman, Drago, Jack Evans, and Psicosis.[16]
