Nicho el Millionario
Psicosis debuted in 1991 and was trained by Rey Mysterio, Sr. Not long after his debut, he would begin his legendary feud with Rey Mysterio Jr..
His first North America exposure was in the form of the AAA/IWC When Worlds Collide Pay-Per-View on November 6, 1994. He competed in a six-man tag team match with Fuerza Guerrera and Madonna's Boyfriend against Rey Mysterio, Jr., Heavy Metal and Latin Lover, and won the contest after Fuerza Guerrera forced Heavy Metal to submit.
Psicosis would soon carry his feud with Rey Mysterio, Jr. over to the Philadelphia-based promotion, Extreme Championship Wrestling. Regardless of the critics telling ECW booker Paul Heyman that "Lucha Libre would not go over in the United States", Psicosis and Rey Mysterio, Jr. ended up putting on the best match on the card a total of three times in the Fall of 1995. The first match was won by Rey Mysterio, Jr., with Psicosis then defeating Mysterio in a 2-out-of-3 Falls Match not long after, and then Mysterio ended the feud (temporarily) by defeating Psicosis in a Mexican Death Match, despite the fact that Psicosis dominated the match the entire time and scored several pinfalls over Mysterio.
Psicosis debuted for World Championship Wrestling at Clash of the Champions on January 26, 1996 and lost to Konnan. Initially, Psicosis was managed by Sonny Onoo, but soon went without a manager and became a frequent tag-team partner of La Parka and Juventud Guerrera, as well as feuding with the likes of Dean Malenko, Rey Mysterio, Jr. and Billy Kidman. Psicosis was a big part of the Latino World Order, as he joined the stable (led by Eddie Guerrero) in October 1998. On April 19, 1999 Psicosis defeated Blitzkrieg, Juventud Guerrera and Rey Mysterio in a 4-way to win the WCW Cruiserweight Championship for the first time, only to lose it to Rey Mysterio not long after. Psicosis lost his mask on September 27, 1999, after losing to Billy Kidman "Hair vs Mask" match. Psicosis would go on to win the WCW Cruiserweight Championship for the second time in October 1999, after defeating Lenny Lane, who had gotten WCW in trouble with GLAAD. Psicosis soon dropped the WCW Cruiserweight Championship to Disco Inferno.
In the beginning of 2000, Psicosis ended up as Juventud Guerrera's bodyguard, as Guerrera would start imitating former WWE Champion the Rock, while Psicosis would stand around with his arms folded and not say a word or do anything. Psicosis was eventually released and headed back to Extreme Championship Wrestling.
Psicosis returned to Extreme Championship Wrestling on July 16 at ECW's Heat Wave 2000 Pay-Per-View and competed in an impromptu 4-Way Dace against Yoshihiro Tajiri, Little Guido and Mikey Whipwreck. Psicosis was eliminated by Tajiri, and would end up competiting against Tajiri in a feud that many still talk about to this day. Psicosis didn't last very long in ECW, and soon resurfaced in the short-lived World Wrestling All-Stars (WWA) promotion based out of Australia.
Psicosis was featured on the Pay-Per-View debut of TNA, but did not last long. Psicosis headed to Xtreme Pro Wrestling (XPW), where he was a part of the La Familia stable, along with Konnan, Juventud Guerrera, Damien 666 and Halloween. Psicosis engaged in a short-lived feud with Super Crazy once XPW relocated to Philadelphia, Pennsylvania, with Psicosis winning both matches at the New Alhambra (formerly ECW) Arena. Psicosis would go on to compete in matches against Chris Chetti, Sonny Siaki, Jerry Lynn and Juventud Guerrera until he left XPW and drifted around the independent circuit for almost three years.
On April 1, 2005 Psicosis signed a contract with World Wrestling Entertainment and debuted on June 12, 2005 at the ECW One Night Stand Pay-Per-View. He entered the ring wearing his trademark mask, but removed it before his match against long-time rival Rey Mysterio Jr.. Mysterio defeated Psicosis with his (Mysterio) signature move, "The West Coast Pop". A few weeks later, Psicosis debuted on the SmackDown! brand as a member of the Mexicools, along with Juventud Guerrera and Super Crazy. Their trademark accessories were riding to the ring on their "Juan Deere" lawnmowers and wearing work clothes. Juventud Guerrera would soon be released from WWE, leaving Psicosis and Super Crazy to go after the World Tag Team championships. They would be unsuccessful every time.
On June 9, 2006 Psicosis abandoned Super Crazy, and they were in the process of developing a feud, until Super Crazy was suspended for elevated enzymes in his liver. As a result, Psicosis was removed from WWE television, as creative had nothing else planned for him. Both men's last televised match on SmackDown! was on July 21, 2006. Crazy was later drafted to WWE's RAW brand in September 2006, while Psicosis remained off SmackDown programming. He was inevitably released from his contract in late 2006.
He is currently performing as Nicho El Millionaro in Consejo Mundial de Lucha Libre (CMLL). At the end of 2006, he accidentally shattered his nose in a match against Hijo del Misterio, and also got his head shaved. He was rushed to a nearby hospital to get his nose set following the match.
The newspaper story claims that Psicosis asked to borrow Ramirez's black Mitsubishi, promising to return it later that night. Ramirez refused, leading to Psicosis pulling a gun on him and taking the car anyway. Ramirez called the police who set up roadblocks around Rosarito. Psicosis hit several cars while in the chase including one that had a pregnant woman inside. After catching him, police found out that the gun he used earlier in the night was actually just a water gun. 
There's a different Psicosis II who began using the same name and look after this Psicosis left to Promo Azteca and WCW, as a result of AAA booker Antonio Peña claiming ownership to the Psicosis name and gimmick. Because of this, Psicosis took on the moniker Nicho el Millonario and returned briefly to AAA to feud with Psicosis II over the name.
