Savio Vega

Juan Rivera (born August 10, 1964) is a retired Puerto Rican professional wrestler. He is signed to WWE as a producer via its sister promotion Lucha Libre AAA Worldwide.

He is known for his work in the World Wrestling Council, where he won the WWC Universal Heavyweight Championship three times and the WWC Puerto Rico Heavyweight Championship three times. During the 1990s, he worked for the World Wrestling Federation (WWF), initially under the masked, villainous and venom-spewing Kwang gimmick. He later portrayed Savio Vega, the eventual leader of a Puerto Ricanstable, Los Boricuas.

After leaving the WWF in 1999, Rivera returned to Puerto Rico and joined Víctor Quiñones' promotion, the International Wrestling Association, where he was a long-time general manager and won five titles, including the IWA Undisputed World Heavyweight Championship. In 2011, he was featured in the first interpromotional angle between IWA and WWC.
