Rush

William Arturo Muñoz González (born September 29, 1988) is a Mexican luchador (Spanish for professional wrestler), known under the ring name Rush.

He is currently signed to AEW.

He is best known for his time performing for the Mexican professional wrestling promotion Consejo Mundial de Lucha Libre (CMLL) as well as the U.S. based Ring of Honor (ROH).

Muñoz's father, Arturo Muñoz, is also a professional wrestler, most recently known under the ring name La Bestia del Ring.

William's younger brothers are also professional wrestlers, using the ring names Dralístico and Dragon Lee.

While most luchadors portray clear heroes or villains in the ring, Rush portrays a character that straddles that divide; his in-ring actions are often chaotic or brawling, with tendencies to cheat, but he is still popular with fans.

Muñoz made his in-ring debut in 2007, working under the name Latino until he started working for CMLL in 2009, where he was given the name "Rush".

He is a former CMLL World Light Heavyweight Champion, multiple time CMLL World Tag Team Champion, CMLL World Trios Champion and two-time Mexican National Trios Champion.

He made his in-ring debut on July 29, 2007.

Muñoz made his debut for International Wrestling Revolution Group (IWRG) in October 2008, performing under the ring name Latino.

He would wrestle midcard matches for IWRG for eight months, before making his final appearance on June 7, 2009.

During the summer of 2009, Muñoz was signed by one of Mexico's top promotions, Consejo Mundial de Lucha Libre (CMLL), and given the new ring name Rouge, which was soon afterwards tweaked to its current form, Rush.

He would make his debut for the promotion on August 9, teaming with Mictlán and Stuka Jr.. to defeat Hooligan, Loco Max and Pólvora in a six-man tag team match.

Rush would spend his first year in the promotion wrestling tag team and six-man tag team matches, often teaming with Máximo, Mictlán, Metro and Toscano.

Despite being booked as a técnico ("Face", or those that portray the good guys), Rush would often show rudo ("heel" or those that portray the bad guys) tendencies during his matches.

During the summer of 2010, Rush entered a feud with Loco Max, which culminated on August 15 in a Hair vs. Hair Lucha de Apuestas match, where Rush was victorious, thus forcing his adversary to have his hair shaved off.

On November 25, Rush won CMLL's Bodybuilding Contest in the advanced category.

With his win, Rush gained the new nickname "Mr. CMLL".

On January 2, 2011, Rush, Ángel de Oro and Diamante defeated Metal Blanco, Palacio Negro and El Sagrado in the finals of a two-week-long tournament to become the number one contenders to the Mexican National Trios Championship.

On January 9, the trio defeated Delta, Metro and Stuka Jr.. to become the new champions.

On February 15, Rush teamed with Máscara Dorada and La Sombra against the team of Averno, Dragón Rojo Jr. and Ephesto and managed to win the match for his team by pinning the CMLL World Light Heavyweight Champion Ephesto, afterwards challenging him to a match for the title.

The title match took place on February 22 and saw Rush defeat Ephesto to become the new CMLL World Light Heavyweight Champion.

In response to the backlash over his sudden push, Rush acknowledged his many detractors by posting a list of the various moves he could do in the ring, while also promoting his youth, strength and physique.

After successfully defending the CMLL World Light Heavyweight Championship against Rey Bucanero and Psicosis, Rush was granted a shot at the CMLL World Heavyweight Championship, held by Último Guerrero.

The title match took place on June 12 and saw Guerrero retain his title two falls to one.

Afterwards, Rush began feuding with Japanese wrestler Yoshihashi, which led to the two agreeing to face each other in a Hair vs. Hair Lucha de Apuestas.

On August 1, Rush defeated Yoshihashi two falls to one to win his second Hair vs. Hair match.

On August 23, 2012, Rush made his third successful defense of the CMLL World Light Heavyweight Championship by defeating Mr. Águila.

On September 20, Rush, Ángel de Oro and Diamante lost the Mexican National Trios Championship to Los Invasores (Olímpico, Psicosis and Volador Jr.).

On November 13, Rush successfully defended the CMLL World Light Heavyweight Championship against El Terrible.

The following month, Rush teamed up with Máximo and the returning Marco Corleone to form La Tercia Sensación, later renamed El Bufete del Amor.

On December 25, Rush and El Terrible survived a torneo cibernetico match used to determine the two competitors in a match for the vacant CMLL World Heavyweight Championship.

On January 1, 2012, El Terrible defeated Rush two falls to one to win the CMLL World Heavyweight Championship.

On January 21 and 22, Rush took part in the CMLL and New Japan Pro-Wrestling (NJPW) co-produced Fantastica Mania 2012 events in Tokyo, teaming with Máscara Dorada losing to the team of Hirooki Goto and Kushida on the first night and losing to Goto in a singles match on the second night.

On February 19, El Bufete del Amor defeated Los Hijos del Averno (Averno, Ephesto and Mephisto) to win the CMLL World Trios Championship.

Also in February, Rush teamed with El Terrible in the National Parejas Increibles tournament, where teams were made up of rivals.

Rush, along with La Sombra and La Máscara, created the group Los Ingobernables ("the unruly") and he was the only original member to remain part of the group in CMLL before departing the promotion in 2019.

The success of Los Ingobernables led to the formation of the Los Ingobernables de Japón (LIJ) group in New Japan Pro-Wrestling (NJPW), of which Rush was a part-time member when he was touring Japan or when LIJ toured Mexico.

Through CMLL's business partnerships, Rush additionally appeared for both NJPW and the U.S. based ROH, and his CMLL contract allowed him to work dates for other companies as well, most notably Major League Wrestling in the U.S., and The Crash Lucha Libre and International Wrestling Revolution Group in Mexico.

William Arturo Muñoz was initially trained for his professional wrestling career by his father Arturo Muñoz Sánchez and his uncles, who worked under the ring names Pit Bull I and Pit Bull II.
