Early Career:
Eddie Guerrero is a professional wrestler performing for World Wrestling Entertainment on the Smackdown! brand. He comes from a legendary wrestling family. His late father, Gory Guerrero, is considered one of the greatest wrestlers in Mexican history. His three brothers Chavo Guerrero, Hector Guerrero and Mando Guerrero all followed in their father's footsteps and became professional wrestlers. Guerrero's nephew, Chavo Guerrero, Jr. also became a wrestler. Guerrero's uncle Enrique Llanes and cousin Javier Llanes are popular wrestlers in Mexico.

Eddie wrestled mainly for Asistencia Asesoria y Administracion (AAA) in Mexico, teaming with Art Barr forming the tag team Los Gringos Locos. They became the most hated team in lucha libre history. They were noticed in late 1994 by the owner of Extreme Championship Wrestling, Paul Heyman, and were to wrestle for him in 1995. Sadly, Art Barr died before he could join ECW with Eddie.

Successes:
While in ECW, Eddie won the ECW World Television Title right away. He also had a series of excellent matches with Dean Malenko before they both jumped to World Championship Wrestling later that year.

In WCW, he found considerable singles success, winning the United States Heavyweight title in late 1996 and two World Cruiserweight titles in 1997. He was involved in a serious car accident in 1997 that almost cost him his life, but returned to the ring a few months afterwards. He turned heel in 1998, a role which he is best at, judging from his days in AAA in Mexico. Around this time, he became unhappy with WCW management and jumped to the then-WWF in 2000, with Chris Benoit, Dean Malenko, and Perry Saturn.

In WWE, he has been fairly successful, spending time as both a heel and a babyface. But by this time, he developed an addiction to pain medication stemming from his 1997 car accident and was briefly released to enter rehabilitation. He would return several months later back in his old form.

Starting in the summer of 2003, he began driving a customized lowrider to ringside as part of his ring entrance. He has become identified sufficiently with lowriders that he appeared on the cover of the February 2004 issue of Lowrider magazine; he is the first man ever to appear on the cover of that publication. (Normally, the cover includes a lowrider and a bikini-clad woman; the Guerrero cover has the same features but adds him.)

Guerrero won his first WWE Championship at WWE's No Way Out pay per view on February 15, 2004, defeating Brock Lesnar. He also has enjoyed success as both a singles and tag team superstar being, at one time in 2003, both the WWE United States and WWE Tag Team Champion simutaneously.

Throughout his career, Guerrero encountered various substance abuse problems outside of wrestling, including alcoholism and an addiction to pain killers. His problems outside of the ring were sometimes integrated into his professional wrestling storylines. Despite all these issues, Guerrero managed to be extremely popular, winning numerous titles during his career, including the WWE Championship. Guerrero became a born again Christian in 2002.
