On June 6, 2010, at Triplemanía XVIII, Aguayo returned to AAA to lead "Perros del Mal" in an invasion of the promotion. The group quickly aligned themselves with Konnan and Dorian Roldan's "La Legión Extranjera", "La Milicia" and "Los Maniacos" to form "La Sociedad". On August 14 at "Verano de Escandalo" El Hijo del Perro Aguayo wrestled his first major match for AAA since his return, when he, L.A. Park and Damián 666 defeated El Mesías, Cibernético and La Parka in a six-man tag team match, when Perro pinned Mesías. On October 1 at "Héroes Inmortales IV" El Mesías defeated Perro in a singles match. Afterwards, Aguayo injured his knee, sidelining him for the rest of the year. However, he made a surprise appearance on December 5, 2010 during the main event of "Guerra de Titanes", helping Damián 666, Halloween and X-Fly hand "Los Psycho Circus" their first-ever loss in a steel cage weapons match. On March 18, 2011, at Rey de Reyes, Aguayo Jr. joined Damián 666, Halloween and Super Crazy in a winning effort against "Potencia Mundial" (Dr. Wagner Jr. and Los Psycho Circus); Aguayo Jr. pinned Wagner with "La Lanza", following a chair shot.
