El Hijo de Dr. Wagner's real name is not a matter of public record, as is often the case with masked wrestlers in Mexico where their private lives are kept a secret from the wrestling fans.

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.

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.

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.

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.

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.

[10] 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.

[11] He teamed up with El Canek Jr. to compete in IWRG's 2011 Guerra de Empresas ("War of the Promotions"), representing the independent circuit.

[13] 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.

On April 18, Wagner and Dupree defeated AXIZ (Go Shiozaki and Katsuhiko Nakajima) in the finals to win the tournament.

[22] The following day, Wagner and Dupree defeated Masaaki Mochizuki and Naomichi Marufuji to win the GHC Tag Team Championship.

[24] 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.

[25] On May 4, Wagner and Dupree defeated Sugiura-gun stablemates Hideki Suzuki and Takashi Sugiura to regain the GHC Tag Team Championship.

[27] 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.
