El Hijo de Dr. Wagner Jr. is the son of Juan Manuel González Barrón and Rossy Moreno, both professional wrestlers with his father working as the masked wrestler Dr. Wagner Jr. He is the grandson of wrestlers Dr. Wagner and Alfonso Morales, patriarchs of the Wagner and Moreno wrestling families. He is the nephew of Silver King ( Son of Dr. Wagner). On his mother's side, he is the nephew of wrestlers Noé Astro Moreno León (better known as El Oriental), Alda Moreno, Esther Moreno, Cynthia Moreno, Mini Cibernético, Groond XXX and Extasis. He was trained for his professional wrestling career by his mother, his Aunt Ester and uncle El Oriental, as they had more of an active role in his training that Juan Manuel González since the divorce of González and Moreno.
In lucha libre, 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. It has not been verified that El Hijo de Dr. Wagner worked under a different identity before December 9, 2009, when he made his debut under that name, but it is possible that the debut date given is only for the "El Hijo de Dr. Wagner" character. 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. In March, 2010, he teamed up with his father for a show in Monterrey, Nuevo Leon, where they lost to Lucha Libre AAA World Wide (AAA) representatives El Mesias and Black Warrior. Three days later, he teamed up with lucha libre legends Blue Demon Jr. and El Hijo del Santo; the trio lost to Los Perros del Mal (Damian 666, Halloween and Mr. Águila) when Hijo de Dr. Wagner was pinned. His father had had a long running rivalry with L.A. Park, a rivalry that would extend to the next generation as El Hijo de Dr. Wagner began working against El Hijo de L.A. Park throughout Mexico. 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 ("Bicentenial 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. A few months later, OILL held a ''Ruleta de la Muete tag team tournament, where the losing team would advance in the tournament and then at the end the last team would face off under Luchas de Apuestas ("Bet match") rules where the loser would be forced to unmask. The tournament included the teams of Hijo de Dr. Wagner and Máscara Jr., Histeria and El Hijo de Fishman, El Canek Jr. and Black Abyss. Hijo de Dr. Wagner's team lost to Canek Jr. and Black Abyss and thus were forced to wrestle against each other with their masks on the line. In the end, Hijo de Dr. Wagner pinned his opponent, forcing Máscara Jr. to unmask.
On July 12, 2010, Hijo de Dr. Wagner worked the Promociones Gutiérrez 1st Anniversary Show, a show co-produced by the local promotion and Consejo Mundial de Lucha Libre (CMLL), one of Mexico's biggest promotions. Hijo de Dr. Wagner teamed up with Hijo de L.A. Park and Scorpio Jr. to take on CMLL regulars La Máscara, Mascara Dorada and Valiente. The teams split the first two falls between them and, in the final fall, Scorpio Jr. drew a disqualification for landing a low blow on La Máscara and subsequently unmasking him in front of the referee. 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 half way 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.Organizacion Independiente de Lucha Libre
