Hijo del Signo

In late 2018, El Hijo del Signo and Yago became involved in a storyline feud against fellow rudos Camorra and Akuma. The two sides faced off in various matches through November and December and often involved either Akuma's or Yago's mask being torn. The feud led to a tag team Lucha de Apuestas, or "Bet match" where Akuma and Yago put their masks on the line and Camorra and El Hijo del Signo bet their hair on the outcome of the match. The match took place on January 1, 2019, as part of CMLL's annual Sin PIedad and saw El Hijo del Signo and Yago win the match. After the match Camorra was shaved bald while Akuma was forced to remove his mask and reveal his real name, Jose Luis Florenico Matinez.

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.
