CMLL introduced Generacion 2011 in early 2011 which a group of young wrestlers who all made their debut around the same time, they were not considered an actual group, more of a graduating class of the CMLL wrestling schools.

Hijo del Signo made his CMLL in ring debut on December 28, 2010, teaming with Puma King and Tiger Kid, losing to the team of Enrique Vera Jr., Metal Blanco and Palacio Negro.

In early 2013 Hijo del Signo became involved in a storyline feud against the veteran tecnico ("good guy" character) Metálico, a storyline that saw Hijo del Signo cheat more than once to defeat Metálico in various six-man tag team matches. The two found themselves on opposites sides of a match at the Arena Coliseo 70th Anniversary Show on April 7, 2013 with Metálico teaming up with Hombre Bala Jr. and Super Halcón Jr. while El Hijo del Signo teamed up with Nosferatu and Taurus. The storyline between Hijo del Signo and Metálico took center stage during the match as most of the action centered around the two. In the second fall Hijo del Signo pulled Metálico's mask off, hoping to use the distraction to gain a pinfall, but instead he was disqualified when the referee saw the blatant rulebreaking by El Hijo del Signo. The storyline between the two was also featured a number of other shows throughout March and April, including a one-on-one match on CMLL's Super Viernes show, their main weekly show and an indicator that CMLL is escalating the storyline between the two. At the Arena Mexico 57th Anniversary Show Hijo del Signo teamed up with Los Guerreros Tuareg (Arkangel de la Muerte and Skándalo) to defeat Metálico, Sensei and Soberano Jr. with El Hijo del Signo scoring the deciding pinfall on Metálico.Signature moves
