Horus began wrestling in 2007 in some Tijuana promotions. On May 27, 2011, since the retirement of El Hijo de Rey Misterio, he was presented by both Rey Misterio Sr. and Konnan as the second El Hijo de Rey Misterio, making his debut in Tijuana. His first match as Misterio was a tournament to crown the WWA World Welterweight Champion on May 27, 2011, which Horus won. In 2014, Misterio changed his name to Rey Horus, because the original El Hijo de Rey Misterio returned to wrestling. On March 27, 2015, Horus made his biggest appearance in the United States when he participated in the WrestleMania Weekend King of Indies tournament. Horus defeated Lil Cholo in the first round, but on March 28 he was defeated by Willie Mack in the quarter-final match. On April 6, 2015, Evolve announced Horus as AR Fox's substitute at Evolve 41. On September 1, 2017, Horus entered Pro Wrestling Guerrilla's 2017 Battle of Los Angeles, losing to Rey Fenix in his first round match.
In the debut episode of Lucha Underground on October 29, 2014, the opening scene featured an unnamed character being rescued from multiple attackers by the green masked Dragon Azteca. This led to Dragon Azteca mentoring the white-hooded unnamed character in lucha libre. During part one of season one's Ultima Lucha, El Dragon Azteca fought his hooded protégé to a draw at the entrance of the Temple where Lucha Underground's matches occurred. Due to the prophecy predicting El Dragon Azteca's death if he entered the Temple, the hooded man offered to go in Azteca's place to rescue Black Lotus from Dario Cueto. Azteca refused to listen, vowing that his spirit would live on after his death. Following the storyline death of Dragon Azteca, his mask was taken up by his student. In late 2015 Horus took part in Lucha Underground first appearing in the Season 1 finale as a nameless outside spectator but at Ultima Lucha 1 took up the mask of his master and became known as Dragon Azteca Jr. In Season 2 Dragon Azteca Jr. started participating in matches and won The Lucha Underground Trios Championship along with Prince Puma & Rey Mysterio. In Season 4, he would defeat Dezmond X and King Cuerno to win the Gift of the Gods Championship, but he lost it against Marty The Moth Martinez. The serie was discontinued after season finale, Ultima Lucha Cuatro.
