In May, 2015 CMLL competed in a qualifying match for the 2015 version of En Busca de un Ídoloas one of 16 wrestlers in the qualifying torneo cibernetico, elimination match where the last eight wrestlers wpild qualify for the tournament. He competed againstAkuma, Blue Panther Jr., Cancerbero, Canelo Casas, Disturbio, Esfinge, Flyer, El Gallo, Guerrero Maya Jr., Joker, Pegasso, Raziel, Sagrado, Stigma and Boby Zavala. During the match Delta eliminated Cancerbero and was one of the eight wrestlers to survive the match. During the En Busca de un Ídolo the wrestlers would face off in a round-robin first round earning points based on the outcome. After the match each wrestler would receive critique and points from a four-man judging panel rating them on the match they just saw. Finally all wrestlers would be given additional points from a weekly online poll open to fans. During the first round Delta defeated Boby Zavala, Esfinge and Flyer but would end up losing to Canelo Casas, Disturbio and his tag team partner Guerrero Maya Jr. For the final match Delta was supposed to wrestle Blue Panther Jr. as part of the 2015 Sin Salida show, but Blue Panther Jr. did not show up so Delta defeated Hechicero instead. The tournament saw several of the judges be very critical of Delta's performances during the matches, although it was acknowledge that at least some of the early problems were due to a knee injury. Delta's lowest score was a 20 out of 40 and his highest was 27 points. Delta ended up with 132 points in total from the judges, the lowest of all eight wrestlers. In the end Delta was eliminated from the tournament before the final week's poll results as he was over 40 points out of fourth place making it impossible for him to move that far up the rankings. On August 9, 2015 Los Reyes de la Atlantida lost the Mexican National Trios Championship to Los Hijos del Infierno ("The Sons of the Inferno"; Ephesto, Mephisto and Lucifierno), ending their third reign as champions.
