Early years (2006–2008) Puma is part of the Casas wrestling family, the son of
Jorge Luis Casas (El Felino) and nephew of
Negro Casas and
Erick Casas. Originally he claimed not to be the son of Jorge Luis, but claimed to be the son of another Casas sibling that is not involved with wrestling. He made his wrestling debut in 2006 at the age of just 16, wrestling under the
ring name Puma King. In an interview with
Súper Luchas published in early June 2010 El Felino finally revealed that he was indeed the father of both Tiger Kid and Puma King, but had kept it a secret to allow his children to succeed or fail on their own merits and not because of their family relationship to El Felino.
Consejo Mundial de Lucha Libre (2008–2018) Puma King worked for
International Wrestling Revolution Group (IWRG) not long after his debut, and although Tiger Kid also worked for IWRG the promotion only rarely used them as a team. In 2008 Puma King joined Tiger Kid in
Consejo Mundial de Lucha Libre (CMLL), the same promotion their uncles worked for. Both Puma King and Tiger Kid participated in the
Trofeo Generacion Del 75 torneo cibernetico match, a tournament for wrestlers signifying the "future of CMLL during their 75th year", but lost as
El Hijo del Fantasma won the trophy. Puma King teamed up with
Villano V to participate in the 2008
Gran Alternativa tournament. The
Gran Alternativa tournament is an annual CMLL tournament that teams a veteran and a rookie (
Novato) up for a
tag team tournament. Villano V was originally scheduled to team with El Brujo, but due to an injury Puma King was chosen to replace him. Puma King and Villano V lost to
Axxel and
Blue Panther in the opening round of the tournament. In CMLL Puma King and Tiger Kid frequently wrestle as a tag team, usually low on the card but they have made several appearances on
CMLL Super Viernes, CMLL's biggest show of the week. In February, 2010 both Puma King and Tiger Kid became involved in El Felino's ongoing feud against
La Sombra. It all began on February 2, 2010, where Puma King dressed up like his uncle El Felino to distract La Sombra during a match. A later doubleganger act backfired though and saw El Felino lose to La Sombra, which saw the end of the Tiger Kid/Puma King aid in the storyline. On April 23, 2010, Puma King participated in the 2010
Gran Alternativa, this time teaming with
Último Guerrero. The team defeated
Pegasso and
Toscano in the first round and
Durango Kid and
El Texano, Jr. in the second round. In the finals of Block B Puma King and Último Guerrero were defeated by
Delta and
Volador Jr. Puma King was one of 12 men who put their mask on the line as part of a 12-man
steel cage match in the main event of the 2010
Infierno en el Ring. Early in the match his own brother, Tiger Kid, had betrayed his brother in order to escape the cage. Later on Puma King feigned an alliance with rival
Ángel de Oro so they could both escape, only to turn on him and escape while Ángel de Oro remained in the cage. In the end Ángel de Oro defeated Fabián el Gitano in the
Lucha de Apueta (bet match) portion of the match to unmask him. Puma King competed in CMLL's first ever
En Busca de un Ídolo ("In search of an Idol") tournament, but did not qualify for the semi-final part of the tournament. On September 14, 2012, at CMLL's
79th Anniversary Show, Puma King defeated
Rey Cometa in a
Lucha de Apuestas, forcing his rival to unmask himself. On December 25, 2015, as part of CMLL's annual
Infierno en el Ring show Puma was one of twelve men risking their mask in the main event
steel cage match. He was the second man to leave the cage, keeping his mask safe in the process. On July 17, 2018, Puma announced his departure from CMLL.
Lucha Libre AAA Worldwide (2018–present) On July 22, 2018, Puma made his debut for
Lucha Libre AAA Worldwide, working the main event of their
AAA vs. Elite show. He was billed as King Puma and teamed up with
L.A. Park and
Electroshock as representatives of Liga Elite. The trio defeated Team AAA (
Psycho Clown,
El Hijo del Fantasma and
Rey Wagner). Puma King,
El Hijo de L.A. Park, and Black Taurus represented Elite in a three-way match for the
AAA World Trios Championship at
Triplemanía XXVI. Team Elite and Team AAA (Mamba,
Máximo, and
Pimpinela Escarlata) lost to defending champions
El Nuevo Poder del Norte (
Carta Brava Jr., Mocho Cota Jr., and
Tito Santana). In the fall of 2018 Puma King was one of 18 wrestlers competing in the
Lucha Capital tournament, losing to
Drago and
Pentagón Jr. to be eliminated from the competition. In addition he has also worked matches for
Impact Wrestling,
All Pro Wrestling,
Game Changer Wrestling and
Major League Wrestling in addition to making regular appearances for
Pro Wrestling Guerrilla (PWG) based in Southern California. This set up an
X Division match between these
four the following week, which Williams won by pinning Lee. Both editions of IMPACT were taped September 13–14 at
Mexico City's Frontón México Entertainment Center. Due to AAA's alliance with American promotion Impact Wrestling, King made a special appearance on the January 12, 2019 edition of Impact Wrestling, which was taped January 11–12, 2019 at Mexico City's Frontón México Entertainment Center, was defeated by
Sami Callihan. The next day, King teamed up with
Aero Star,
El Hijo del Vikingo and
Psycho Clown in an Elimination Match where they defeated
Eddie Edwards,
Eli Drake,
Fallah Bahh and Sami Callihan winning the Impact World Cup. ==Championships and accomplishments==
