Perro Aguayo Jr.

Los Perros del Mal and return to AAA (2008–2015) Aguayo Jr. left CMLL in October 2008, along with fellow Los Perros Del Mal members Damián 666 and Mr. Águila, to start his own promotion called Perros del Mal Producciones. The new promotion's debut show took place on December 7, 2008, in Mexico City. On that show, Aguayo Jr. tag-teamed with Cibernético and Dr. Wagner Jr. to face L.A. Park, Olímpico and Headhunter A, and was victorious.

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.

On April 8, 2011. Aguayo Jr. underwent emergency surgery to remove a golf ball-sized tumor from his stomach. During the surgery, a peptic ulcer burst, and he was placed in an intensive care unit at the hospital in Guadalajara, Jalisco. Aguayo Jr. was released from the hospital on April 19 and was scheduled to receive treatment for his condition for a full year. Aguayo's tumor was found to be benign; Aguayo made his return to AAA, in a non–wrestling role, on May 1 and returned to the ring on May 8 in a six-man tag team match pitting Los Perros del Mal against Los Psycho Circus; Aguayo pinned Psycho Clown after a low blow. The feud continued on May 29 at Perros del Mal Producciones third anniversary show, when Los Psycho Circus defeated Los Perros del Mal in a six-man tag team steel cage mask vs. hair match. As a result, Super Crazy, the last man left in the cage, was shaved bald. Aguayo Jr. was set to wrestle as part of Los Perros del Mal at Triplemanía XIX, facing Los Psycho Circus to determine the first-ever AAA World Trios Champions, but was forced to pull out of the event due to an adverse reaction to the medication given to him as part of his tumor treatment. Aguayo returned on July 24 at a Perros del Mal event, teaming with Damián 666 and Halloween against Blue Demon Jr., Cassandro and L.A. Park; the match ended in a no contest when Park turned on his partners. Aguayo Jr. next returned to AAA on August 19, replacing L.A. Park and teaming with Damián 666 and Halloween against El Mesías, Joe Líder and El Zorro in a six-man tag team match, which they lost via disqualification when Líder was attacked by his former tag team partner Nicho el Millonario. After the match, Aguayo officially named Nicho the newest member of Los Perros del Mal. Aguayo Jr. returned to pay-per-view on October 9, 2011 at Héroes Inmortales, unsuccessfully challenging Dr. Wagner Jr. for the AAA Latin American Championship in a bullterrier match. Afterward, Aguayo Jr. began a feud with Jack Evans. On December 16, 2011 at Guerra de Titanes, Aguayo and Evans continued their rivalry in a six-man tag team match, during which they busted each other open. The match was won when Aguayo Jr.'s teammate Héctor Garza pinned Fénix. The feud between Aguayo Jr. and Evans continued through to Rey de Reyes on March 18, 2012, when Aguayo Jr. pinned Evans to win the Rey de Reyes tournament and earn a chance to contend for the AAA Mega Championship. On August 5 at Triplemanía XX, Aguayo Jr. unsuccessfully challenged El Mesías for the AAA Mega Championship. Afterwards, Aguayo Jr. started a year-long rivalry with Cibernético, which culminated in a lucha de apuesta in the main event of Triplemanía XXI on June 16, 2013. Aguayo Jr. was victorious, forcing Cibernético to have his head shaved bald.

In August 2013, Aguayo teamed with Cibernético against his former stable, La Secta. On October 18 at Héroes Inmortales VII, La Secta eliminated Aguayo Jr., Cibernético, and El Mesías from the Copa Antonio Peña, which led to the three retaliating by costing Secta members Dark Escoria and Dark Espiritu their match for the AAA World Tag Team Championship. Aguayo Jr.'s tecnico turn was completed on November 22, when Los Perros del Mal members Daga and Psicosis turned on him, labeling him a traitor for teaming with Cibernético. However, on December 8 at Guerra de Titanes, Aguayo Jr. turned on Cibernético, rejoined Daga and Psicosis and brought Los Perros del Mal back under the umbrella of the reformed La Sociedad. On August 17, 2014, at Triplemanía XXII, Aguayo Jr. started a new feud with the debuting El Patrón by attacking him and his father Dos Caras at the start of the show. Later that night in the main event, Aguayo Jr. defeated Cibernético, Dr. Wagner Jr. and Myzteziz, in a four-way elimination match to win Copa Triplemanía XXII. After the match, Aguayo Jr. was immediately attacked by El Patrón. Subsequently, Aguayo Jr. and El Texano Jr. defeated El Patrón and El Mesías at Héroes Inmortales VIII. In subsequent months, Aguayo Jr. focused on Myzteziz, and resuming the storyline that started in CMLL when Myzteziz was known as Místico, by issuing a challenge for a mask vs. hair match at Triplemanía XXIII. The story led to the main event of the 2015 Rey de Reyes, in which Aguayo Jr. teamed up with Pentagón Jr., only to lose to Myzteziz and the returning Rey Mysterio Jr.

Death On March 20, 2015, Aguayo wrestled a tag team match, teaming with Manik against Rey Mysterio Jr. and Xtreme Tiger at a show for The Crash promotion in Tijuana, Baja California, Mexico. During the match, Mysterio used a headscissors takedown which according to him was supposed to propel Aguayo into the 619 position on the ropes, but for some reason he bumped and went out to the floor. Aguayo returned to the ring, upon which Mysterio dropkicked him in the shoulder to again set up for the 619 as he landed on the middle rope (the proper position for the 619). Aguayo appeared to attempt to stand up with his left leg. Manik then fell onto the middle rope beside Aguayo; when he appeared to be limp and unconscious, Manik shook him slightly to revive him. Mysterio bounced off the middle rope to perform the 619, but did not hit either opponent as Aguayo was already slumped over the middle rope and Manik ducked. While the match continued, Konnan, who was at ringside, then attempted to revive the seemingly unconscious Aguayo by shaking him. The match continued, with Mysterio next checking on the unmoving Aguayo, bringing it to the referee's attention. Mysterio then pinned Manik to end the match while Konnan again attempted to revive Aguayo.

With the match over, various personnel went to Aguayo, believing he was just unconscious and in need of medical help. Officials later brought him out of the ring. When paramedics arrived, Aguayo was brought to the local Del Prado hospital, where he was pronounced dead around 1:00 am on March 21. He was 35 years old.

According to the initial statement by the hospital, Aguayo died from a cervical spine trauma, reportedly as a result of the dropkick by Mysterio Jr. that propelled him forward to the ring ropes, causing severe whiplash trauma that snapped his neck. The cause of death was later determined as cardiac arrest, due to a cervical stroke caused by three fractured vertebrae. Autopsy results showed that Aguayo Jr. broke his C-1, C-2, and C-3 vertebrae. The coroner stated that the fractures took place at two different moments of impact and that Aguayo died almost instantly. An alternative angle uploaded by an audience member appears to show Aguayo moving his left leg after the initial impact. On March 21, the attorney general for Baja California conducted an investigation into Aguayo's death but no criminal charges were filed.

Aguayo Jr. was buried in Guadalajara on March 23 with Konnan and Rey Mysterio Jr. serving as pallbearers. Out of respect for Aguayo Jr, Rey attended the funeral without his mask. Mysterio's wife stated he went to the funeral as a human being, not a wrestler. Mysterio was devastated and faced Perro's family to give them his condolences. Perro's family told Rey Mysterio to "Not feel guilt, this was in God's hands, they understood completely." After his death, the Comisión de Deporte del Senado del México (The Commission of Sport of the Mexican Senate) presented the initiative "Ley para la Seguridad del Deporte en el País" (Law for the Safety of Sport in the Country").

Many promotions, including AAA, CMLL, The Crash, Lucha Underground and World Wrestling League (WWL), paid tribute to Aguayo Jr. following his death. On August 9, 2015, at Triplemanía XXIII, Aguayo Jr. was inducted into the AAA Hall of Fame.
