Mexico (2009–present) In Mexico, masked wrestlers closely guard their private lives, which means that if they have never been officially unmasked during their career their birth names are kept secret from the general public. Some wrestlers, especially second or third-generation wrestlers, often assume a different
ring identity before revealing their family relationship. Before his official debut, he was at times referred to as "Dr. Wagner III" ("Dr. Wagner the Third") by some
lucha libre publications, but that name was never officially used. He made his debut on a
Perros del Mal show on December 25, 2009, teaming with
C. Manson,
X-Fly and his uncle Groon XXX; the team defeated El Oriental,
Halloween,
Hysteria Extreme and
Máscara Año 2000 Jr. The rivalry saw the Wagners take on the Parks in a match on September 2, 2010, where Dr. Wagner Jr. and his son defeated L.A. Park and his son. A few days later, Hijo de Dr. Wagner and Hijo de L.A. Park were teamed up for ''Organizacion Independiente de Lucha Libre's
(OILL) Torneo De Parejas Juniors Bicentenario'' ("Bicentennial Juniors Tag Team Tournament"). The two rivals were able to defeat
Kung Fu Jr. and
Ultraman Jr. in the semi-finals and then defeat
El Hijo del Fishman and
El Hijo del Canek in the finals to win the tournament. After the match, Scorpio Jr. and Hijo de L.A. Park attacked Hijo de Dr. Wagner Jr., which resulted in the surprise of the night as his father, Dr. Wagner Jr., came to the ring to save him from the attack. Dr. Wagner Jr. came out in full wrestling gear, with the
AAA Mega Championship strapped around his waist to the surprise of everyone in attendance. After running off his son's attackers, he posed in the ring with his son, then circled the ring to allow the front row to get a closer look at him. Dr. Wagner Jr. did not make any announcements or comments during his appearance, just posed with his son and interacted with the fans before leaving the arena. In 2010, El Hijo de Dr. Wagner formed a regular tag team with
El Hijo del Medico Asesino called
La Ola Blanca, referencing the team of Dr. Wagner and
Ángel Blanco. The duo worked for a number of independent promotions in Mexico until El Hijo del Medico Asesino signed a development contract with
World Wrestling Entertainment in the early part of 2011. El Hijo de Dr. Wagner began making regular appearances for
International Wrestling Revolution Group (IWRG) in 2011, including the main event of IWRG's
Guerra del Golfo ("Gulf War") show in which he wrestled in a
Steel cage match where the loser would be forced to defend his mask later that night in a
Luchas de Apuestas match. The match also included
Black Terry,
El Ángel,
El Hijo del Diablo,
El Hijo del Pantera,
Masada and
Trauma I and loser
Multifacético. He teamed up with El Canek Jr. to compete in IWRG's 2011
Guerra de Empresas ("War of the Promotions"), representing the independent circuit. The team lost to AAA representatives
Los Psycho Circus (
Monster Clown and
Psycho Clown) in the first round of the tournament. Less than a month later, IWRG held another
Guerra de Empresas tournament; this time he teamed up with Trauma I, only to be eliminated in the first round when they, as well as opponents
El Hijo de Pirata Morgan and
Lizmark Jr., were both counted out. In late 2011, El Hijo de Dr. Wagner was one of several wrestlers who worked a "try out" for WWE, hoping to impress the officials enough to earn a contract. At the time, El Hijo de Dr. Wagner was not offered a contract. On March 15, 2012, El Hijo de Dr. Wagner was one of ten men wrestling in the main event of IWRG's
Rebelión de los Juniors where the winner would get a match for the
IWRG Junior de Juniors Championship later on. The match was contested under
torneo cibernetico elimination rules. It also included
Apolo Estrada Jr.,
Bestia 666,
Carta Brava Jr., El Canek Jr., El Hijo de L.A. Park, Halcón 78 Jr., Hijo de Pirata Morgan,
Máscara Sagrada Jr. and
Ultraman Jr. Hijo de Dr. Wagner was the seventh man eliminated from the match as he was pinned by rival Hijo de L.A. Park. A few months later he was one of 10 men who competed in a
Luchas de Apuestas steel cage match along with rival El Hijo de L.A. Park, El Ángel,
Oficial AK-47,
Carta Brava Jr., Carta Brava Jr. (II),
Oficial Factor,
El Hijo de Máscara Año 2000, El Hijo de Pirata Morgan,
Veneno and
Violencia Jr. Hijo de Dr. Wagner escaped the cage about halfway through, keeping his mask safe. The following month he competed in yet another steel cage match with the same concept, called
El Castillo del Terror ("The Tower of Terror"), and again with his main rival El Hijo de L.A. Park as one of the other nine participants. Once again, Hijo de Dr. Wagner mainly focused on Hijo de L.A. Park throughout the match and escaped the cage only moments before his rival was able to do the same, keeping his mask safe. For IWRG's celebration of
Arena Naucalpan 35th Anniversary, Hijo de Dr. Wagner teamed up with his father to face four other "wrestling families" inside a steel cage: the families included the Canek family (
Canek and Canek Jr.),
La Familia de Tijuana (Damian 666 and X-Fly),
Los Junior Dinamitas (Máscara Año 2000 Jr. and Hijo de Máscara Año 2000) and
Los Piratas (
Pirata Morgan and Hijo de Pirata Morgan. The match ended when
Los Piratas were the last wrestlers in the ring after the Wagners were able to escape.
Pro Wrestling Noah (2019–2025) On July 29, 2019, as part of a working relationship between
Pro Wrestling Noah and
Major League Wrestling, it was announced that El Hijo de Dr. Wagner Jr., would take part of Noah's premier tournament
N-1 Victory. The following month, Wagner finished the tournament with a record of one win and four losses, failing to advance to the finals of the tournament. During the tournament, Wagner joined the
Sugiura-gun stable, as its first gaijin member. In April 2020, as part of Sugiura-gun, Wagner and Sugiura-gun newest member
Rene Dupree formed the Sugiura-gun International. Afterwards, Wagner and Dupree took part in the
2020 Global Tag League, finishing the tournament with a record of two wins and one loss, advancing to the finals of the tournament. On April 18, Wagner and Dupree defeated AXIZ (
Go Shiozaki and
Katsuhiko Nakajima) in the finals to win the tournament. The following day, Wagner and Dupree defeated
Masaaki Mochizuki and
Naomichi Marufuji to win the
GHC Tag Team Championship. On August 10, Wagner and Dupree returned the titles to Noah, due to being unable to attend Noah's events in relation to travel restrictions because of the COVID-19 pandemic, vacating the titles in the process. Following the mitigation of the COVID-19 travel restrictions, on March 23, 2022, it was announced that Wagner and Dupree, billed as "Les Mexicanas" would be returning to Sugiura-gun on April 30 at
Majestic. On May 4, Wagner and Dupree defeated Sugiura-gun stablemates
Hideki Suzuki and
Takashi Sugiura to regain the GHC Tag Team Championship. They lost the titles to Masa Kitamiya and Michael Elgin on May 21. On November 10 at
Global Honored Crown 2022, Wagner defeated
Masakatsu Funaki to win the
GHC National Championship, becoming the first non-Japanese wrestler to hold the title. In August 2023, Wagner took part in the 2023 N-1 Victory, finishing the tournament with a record of four wins and three losses, failing to advance to the finals of the tournament. On October 28 at
Demolition Stage In Fukuoka, Wagner Jr. lost the GHC National Championship to
Jack Morris, in his seventh title defense, ending his reign at 352 days, the longest reign in the title's history. On January 13, 2024, Wagner challenged
Kenoh to a title match for the
GHC Heavyweight Championship. Wagner wanted to challenge him in 2019, with Kenoh accepting. Afterwards, Kenoh offered a handshake, which he accepted and then pulled Kenoh close so the two were butting heads. On February 4 at
Cross Over in Sendai 2024, Wagner defeated Kenoh to win the GHC Heavyweight Championship, for the first time. With this victory, Wagner became the second gaijin wrestler (the other being
Eddie Edwards) and the first Mexican to hold the title. He lost the title to Kaito Kiyomiya on May 4 at
Wrestle Magic. In August, Wagner took part in the
2024 N-1 Victory. Despite winning his opening match, on August 11, it was announced that Wagner would be absent the remainder of the tournament due to injury, leading him to forfeit the remainder of his matches. He made his return from injury on September 1. On October 25, 2025 at
NXT Halloween Havoc, Wagner unsuccessfully challenged for
Ethan Page's
NXT North American Championship in a Day of The Dead Deathmatch. During the match, his mask was half-ripped. On December 20, 2025 at
Guerra de Titanes, Wagner successfully retained the AAA Latin American Championship against Ethan Page. ==Championships and accomplishments==
