Gran Guerrero

Taurus (2012–2013)

Shortly after his DragonMania VII appearance Taurus was announced as part of Consejo Mundial de Lucha Libre's (CMLL) Generacion 2012, a group of young wrestlers who made their debut in 2012, involving Guerrero Negro Jr., Espanto Jr., Akuma, Herodes Jr., Oro Jr. and Génesis.^[9] Taurus made his CMLL in-ring debut on June 18, 2012, teaming with Bobby Zavala and Hooligan as the team lost to Leono, Metálico, and Sensei. Taurus was the last of the Generacion 2012 wrestlers to make his CMLL Super Viernes (CMLL's main show) debut, as he teamed with Zayco to lose to Leono and Metálico on the September 28 show.^[10][11] On October 14, Taurus worked a Toryumon benefit show for injured wrestler Electrico, where he, El Hijo del Medico Asesino and El Hijo del Signo defeated Magnus, Mr. Rolling, and Platino.^[12]

In early 2013, Taurus teamed up with Zumba to compete in Toryumon's 16th 2Torneo Juvenil Copa Dragon ("Young Dragon Tournament"), defeating fellow Generacion 2012'ers Akuma and Guerrero Negro Jr. in the quarterfinals, but losing to Los Hermanos Celestick in the semi-finals.^[13] Less than two months later, CMLL held their second annual Torneo Sangre Nueva ("The New Blood Tournament"), a tournament that focuses primarily on younger wrestlers or wrestlers who work in the promotion's lower ranks, generally the first or second match of the show, as a way to highlight or promote a wrestler up to a higher level of competition. Taurus was part of qualifying "Block B" of the tournament that competed on March 5 for the other finalist spot, with a field that also included Genesis, Oro Jr., Robin, Sensei, Super Halcón Jr., Disturbio, Guerrero Negro Jr., Inquisidor, and Zayco. Taurus won the torneo cibernetico elimination match, personally eliminating Sensei and Guerrero Negro Jr. to earn a spot in the finals the following week against Soberano Jr.,^[14] who defeated Taurus two falls to one to win the 2013 Sangre Nueva tournament.^[15] Shortly after, Taurus was announced as one of the Novatos, or rookies, in the 2013 Torneo Gran Alternativa, or "Great Alternative tournament", which pairs a rookie with an experienced wrestler.^[16] Taurus and veteran Averno competed in Block A on April 12, defeating Stigma and La Mascara in the first round before losing to Hombre Bala Jr. and Atlantis in the second round.^[17][18]

Gran Guerrero (2013–present)

During the celebration of Atlantis' 30th anniversary as a wrestler, Último Guerrero appeared after a match to berate him, as a part of the long-running storyline between the two. The appearance turned out to be a distraction, as a second Último Guerrero attacked Atlantis from behind. The two identically dressed Guerreros proceeded to beat up Atlantis and tear his mask apart. Following the match, Último Guerrero introduced his brother "Gran Guerrero" and made him a part of Los Guerreros del Infierno.^[19][20] On June 15, 2013, Gran Guerrero outlasted Aeroboy, Comando Negro, El Hijo del Signo, Epidemia, Fusion, Kato Kung Lee, Laberinto, Lucifer, Magnus, Relampago, Robin and Violento Jack to win the DragonMania VIII "Dragon Scramble" match. Gran Guerrero teamed up with Último Guerrero and Niebla Roja to defeat the then reigning CMLL World Trios Champions Los Estetas del Aire (Máscara Dorada, Místico and Valiente) in the semi-final match of the 2014 Homenaje a Dos Leyendas show.^[21]

In March 2017, CMLL began a storyline where Niebla Roja started having problems with his fellow Los Guerreros Laguneros teammates, initially by accidentally causing them to lose matches due to a miscommunication between Roja, Euforia, and Gran Guerrero.^[22] On May 19, Roja's tecnico turn was completed as he kicked Los Guerreros leader Último Guerrero in the face during a match. Afterward, both Guerreros beat up Roja, tore his mask off and demanded for him to come up with a new mask instead of wearing the Último Guerrero inspired one. During the attack, Roja was aided by his brother Ángel de Oro.^[23][24] The long-running storyline rivalry between Gran Guerrero and Niebla Roja led to the main event of CMLL's 84th Anniversary Show on September 16. Both wrestlers put their masks on the line in a Lucha de Apuestas match, which Guerrero won. As a result of Roja's loss, he was forced to unmask afterward.^[25]

On July 1, 2018, Los Guerreros Lagunero ended Sky Team's 1,223-day reign with the CMLL World Trios Championship as they defeated them in the main event of CMLL's Domingos Arena México show.^[26] Subsequently, they were positioned as "Defenders of CMLL" as they began a storyline feud with "The Cl4n" (Ciber the Main Man, The Chris, and Sharlie Rockstar), three wrestlers who had made a name for themselves in CMLL's main rival Lucha Libre AAA Worldwide. On September 14, The Cl4n won the trios championship,^[27] followed by Los Guerreros Lagunero regaining the championship two weeks later on September 28.^[28] On March 26, 2021, they lost the championship to Nueva Generación Dinamita (El Cuatrero, Forastero and Sansón).^[29]

On November 7, 2022, Guerrero defeated Hechicero to win the CMLL World Heavyweight Championship for the first time in his career.^[30] The following month, he was paired with Raider in the Torneo Gran Alternativa, losing to Místico and Panterita del Ring Jr. in the finals.^[31] On March 24, 2023, Los Guerreros Lagunero, which had since gained Stuka Jr. as a new member, unsuccessfully challenged Los Infernales (Euforia, Hechicero and Mephisto) for the CMLL World Trios Championship.^[32] After seven successful defenses of the CMLL World Heavyweight Championship, Guerrero lost the title on November 28, 2025, to Claudio Castagnoli.^[33]
