Konnan started his wrestling career in Mexico. In 1996, he came to America and wrestled for ECW for a few matches but moved to WCW where he gained his most fame, wrestling such superstars as Ric Flair.
He joined the nWo while in WCW, but didn't have much success there. When the nWo split into two, he went with the Wolfpac, but that group quickly fizzled out. He joined up with a group of wrestlers and called themselves the Filthy Animals. They did well as a group, but that ended when WCW was bought by WWE.
He wrestled for a time in Mexico and the US independently. He soon joined NWA TNA Wrestling and teamed up with B G James and Ron Killings to form 3 Live Kru, who won the NWA Tag Team Championships.
Konnan is known for coming to the ring wearing camouflage outfits and saying his catchphrases on the microphone, such as "Odelay" and "Let me speak on this!" He is one of the most successful wrestlers from Mexico in the United States.
