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. 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.
