Oscar Gutierrez (born December 11, 1974) better known by his ring name Rey Mysterio, is an American professional wrestler currently signed to World Wrestling Entertainment (WWE) wrestling on its SmackDown brand. He trained in and started his career in the lucha libre style of Mexico and has achieved success in the heavyweight, cruiserweight and tag team divisions throughout his career. Before wrestling with WWE, he had notable tenures in World Championship Wrestling (WCW) from 1996 to 2001 as well as with Extreme Championship Wrestling (ECW) from 1995 to 1996.
Mysterio is known for having a high flying style, which helped kick-start the cruiserweight wrestling revolution in the United States in the late 1990s during his time in WCW. His total Cruiserweight Championship reigns, 8 (5 in WCW and 3 in WWE), are a record. In WWE, he is a former World Heavyweight Champion, a three-time Cruiserweight Champion, a four-time WWE Tag Team Champion and his Intercontinental Championship win made him the 21st Triple Crown Champion.
He is also the winner of 2006 Royal Rumble. In WCW, he was a five-time Cruiserweight Champion, a three-time World Tag Team Champion and a former Cruiserweight Tag Team Champion with Billy Kidman as part of the Filthy Animals. Born in Chula Vista, California, Oscar Ramon Gutierrez trained for pro wrestling with his uncle, who wrestled under the name Rey Misterio.
He debuted as a wrestler on April 30, 1989 at the age of 14 in a small church in Tijuana, Baja California, Mexico. Technically, he was too young to receive a license, but enforcement was generally low. He began a feud with Psicosis using the ring name Colibrí (Spanish for hummingbird).
The feud lasted several years, continuing even after Mysterio's career moved to the United States of America.
Guru, there is a new Rey Jr. (legitimate son of Rey Mysterio Sr.) You should find a pic of him and change it since the one pictured has dropped "Jr." from his name.
