On the March 3, 2007 televised episode of AAA, Psicosis came as Nicho and started a fight with Cibernético. He had worn a La Parka mask, pretending to be him, in order to get La Parka expelled from AAA. Psicosis then joined Halloween's new version of La Familia de Tijuana, along with Extreme Tiger, in AAA under the ring name Nicho el Millonario. He returned after an absence from the company and joined Joe Líder's new "rudo" stable, while helping attack La Familia de Tijuana and the Mexican Powers. On September 14, 2008 at "Verano de Escandalo", Nicho and Joe Líder, known collectively as "La Hermandad Extrema" (the Extreme Brotherhood), won the AAA World Tag Team Championship by defeating Crazy Boy and Último Gladiador and The Hart Foundation 2.0 (Jack Evans and Teddy Hart) and champions Halloween and Extreme Tiger in a four-way ladder match. "La Hermandad 187" are the longest reigning tag team champions, with a reign of 551 days. On March 19, 2010, they lost the championship to "La Legión Extranjera" representatives Taiji Ishimori and Takeshi Morishima. On June 6, 2010, at Triplemanía XVIII, "La Hermandad 187" participated in a four-way elimination match for the AAA World Tag Team Championship. Lídereliminated the then reigning AAA World Tag Team Champions (Atsushi Aoki and Go Shiozaki) when he pinned Shiozaki. Later, Líder was pinned by James Storm of Beer Money, Inc. after interference from Konnan, denying them the chance to regain the tag team championship. Later in the night "La Hermandad" helped Cibernético beat up almost all the members of "La Legión".
