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.

Afterwards La Hermandad started feuding with La Sociedad, a superstable consisting of invaders from Los Perros del Mal and members of Los Maniacos, La Legión Extrangera and La Milicia, El Zorro and Hernandez in particular.
La Hermandad received their rematch for the AAA World Tag Team Championship from Los Maniacos (Silver King and Último Gladiador) on September 19, 2010, but Líder was forced to enter the match without Nicho, who was taken out by El Zorro, Hernandez and La Legión the previous week, and was unable to regain the championship.
At Héroes Inmortales IV Nicho and Líder gained a measure of revenge on Konnan by defeating him and Perros del Mal members Damián 666 and Halloween in a three–on–two handicap hardcore match.
On October 30, 2010, El Zorro defeated Nicho in a Lucha de Apuesta to take his hair.
On December 5 at Guerra de Titanes Nicho and Líder received a shot at the AAA World Tag Team Championship, but were unable to dethrone Los Maniacos in a three–way ladder match, which also included Hernandez and El Ilegal.
During the first half of 2011, La Hermandad 187 started feuding with La Maniarquía (Chessman, Silver King and Último Gladiador), during which the rudo trio injured Nicho, forcing him out of Triplemanía XIX on June 18.
At the event Nicho tried to interfere in the match between Líder, Electroshock and Heavy Metal and La Maniarquía, but was stopped by AAA president Joaquín Roldan, who suspended him from AAA for his interference and had him removed the arena.
Prior to the start of his three-month-long suspension, Nicho appeared at the June 30 tapings, voicing his displeasure over the suspension, claiming that he had been there for the company from the beginning even though they had given his name (Psicosis) to another performer "not even close to his level", before noting that he had a son and that if he was suspended without pay, he would have to find work from another promotion.
Nicho returned to AAA on July 16, threatening Roldan, which led to Joe Líder trying to calm his partner down.
This in turn led to Nicho declaring that if Líder was with Roldan, they were no longer friends.
Later in the event, Nicho interfered in Líder's match and turned on him, effectively ending La Hermandad 187.
On July 31 at Verano de Escándalo, Nicho attacked Líder during a Monster's Ball match and put him through a flaming table, costing him the match in the process.
On August 19, 2011, Nicho attacked Líder again before putting on a Perros del Mal T-shirt, which led to the group'
