Anselmo Rivas Castro (born November 3, 1982), best known by his ring name Dragón Rojo Jr. (Spanish for "Red Dragon Jr."), is a Mexican professional wrestler. He is signed to Consejo Mundial de Lucha Libre (CMLL), where he is the leader of the Los Dragones stable.

Dragón Rojo Jr. originally wrestled under the ring names Zaracatán Jr. and Diamante Negro. He formerly led the stable Los Revolucionarios del Terror, previously being a member of Poder Mexica and Los Guerreros de la Atlantida. He is a former two-time CMLL World Middleweight Champion (currently holding the record for most days as Middleweight Champion), NWA World Historic Middleweight Champion, CMLL World Tag Team Champion, CMLL World Trios Champion and Mexican National Trios Champion. He has won several tournaments in CMLL, including the Torneo Gran Alternativa in 2008, the La Copa Junior in 2010, and the Reyes del Aire VIP and CMLL Universal Championship in 2023. He has also wrestled in Japan for New Japan Pro-Wrestling (NJPW).

Personal life Anselmo Rivas Castro was born on November 3, 1982, in Gómez Palacio, Durango, Mexico. While it was later claimed that he is the grandson of a professional wrestler from the 1970s called Dragón Rojo, it is believed that this is a storyline relationship only used to explain the ring name, something not uncommon in lucha libre. Dragón Rojo Jr. has a college degree in physical education, which he has taught at the primary school of Ejido Luján in Gómez Palacio, Durango, inspired to become a teacher like his father. He is one of Consejo Mundial de Lucha Libre's ("World Wrestling Council; CMLL) "ambassadors" in their campaign against tuberculosis, raising awareness and money for the fight against the disease. He has a wife and daughter.

Professional wrestling career Early career (2001–2007) After training for two years under Raúl Díaz and Dandy Garcia, he made his debut on June 28, 2001, using the name "Zaracatán Jr.", a masked técnico ("good guy") ring persona. He was named the Lagunero area "Rookie of the year" for his work in the local promotion that put on shows in Torreón and Gómez Palacio in Durango. After his rookie year, he suffered an injury that forced him out of wrestling for two years, while recovering and rehabilitating. When he returned to the ring, he changed his ring personas and became a rudo ("bad guy") character called "Diamante Negro Jr."; the "Jr." was soon dropped. He stated that the five sided diamond on his mask stood for "passion, aggressiveness, strength, dedication, and professionalism", and that it was black because he was a rudo. In 2007, Diamante Negro won the mask of two wrestlers, Tackle and Guerrero, defeating each in a Lucha de Apuestas ("bet match").

Consejo Mundial de Lucha Libre (2007–present) Diamante Negro (2007–2008) In 2007, Diamante Negro was signed by CMLL after being invited to train with them by CMLL mainstay Último Guerrero. He worked mainly on the lower half of the card in trios matches with mixed success. The following year, he was named as a member of "Generación del 75", a group of young wrestlers who exemplified the "CMLL future" in CMLL's 75th anniversary year. The group also included Flash, Mictlán, Tiger Kid, Hijo del Faraón, Axxel, El Hijo del Fantasma, Bronco, Metalik, Puma King, Skándalo, Súper Nova and Vangelis. On May 9, he competed in the Reyes del Aire ("Kings of the Air") tournament, but was the fifth wrestler eliminated from the torneo cibernetico. The following month, Diamante Negro and Bronco were one of sixteen teams entered into a tournament for the revived CMLL Arena Coliseo Tag Team Championship, with the first three rounds commencing on June 22. They defeated Loco Max and Vangelis in the first round and Fabián el Gitano and Mictlán in the quarter-finals, before losing to eventual winners Flash and Stuka Jr. in the semi-finals.

Dragón Rojo Jr. and Poder Mexica (2008–2010) Diamante Negro was scheduled to team with Guerrero in the Torneo Gran Alternativa ("Great Alternative Tournament"). However, on July 17, 2008, it was officially announced that he had changed names and would, from then on, work as "Dragón Rojo Jr.", taking the name of his grandfather "Dragón Rojo"; the new gimmick and mask was noted as bearing a striking resemblance to an animated character of the same name on the show Los Campeones de la Lucha Libre ("The Champions of Wrestling"). The next day, he and Guerrero won the tournament, defeating Dos Caras Jr. and Metalik in the finals. At Sin Piedad ("No Mercy") on August 29, Dragón Rojo Jr. defeated rival Mictlán in a Lucha de Apuestas, forcing him to unmask and reveal his real name. On December 9, he outlasted Black Warrior, Felino, Flash, Heavy Metal, La Máscara, Loco Max, Máscara Dorada, Máscara Púrpura, Mictlán, Stuka Jr. and Virus to become the number one contender for Sangre Azteca's Mexican National Welterweight Championship. The following week, the title match ended in a double countout, meaning that Azteca retained the title.

Dragón Rojo Jr., Azteca and Black Warrior then formed the trio Poder Mexica ("Mexican Power"), defeating El Sagrado, La Sombra and Volador Jr. on February 3, 2009, to win the Mexican National Trios Championship. The following month, Misterioso Jr. replaced Black Warrior in several matches in Mexico City and later became an official member of Poder Mexica. At Homenaje a Dos Leyendas ("Homage to Two Legends") on March 20, Poder Mexica lost to CMLL World Trios Champions El Hijo del Fantasma, Héctor Garza and La Máscara. For holding a championship, Dragón Rojo Jr. participated in the inaugural Universal Championship tournament on June 5, losing to Averno in the first round. At the CMLL 76th Anniversary Show on September 18, Poder Mexica lost to Dorada, El Hijo del Fantasma and El Sagrado. On October 30, he unsuccessfully challenged Valiente for the Mexican National Welterweight Championship. On December 19, it was announced by the Comisión de Box y Lucha Libre Mexico D.F. that Poder Mexica had been stripped of their championship since Black Warrior left CMLL, breaking up the team. At the same time, they announced an eight team tournament to crown a new trios champion. Poder Mexica defeated Fabián el Gitano, Máximo and Rouge and then Delta, Leono and Valiente to qualify for the finals, where they lost to Dorada, Metro and Stuka Jr. on January 6, 2010. For that year's Torneo Nacional de Parejas Increíbles ("National Incredible Pairs Tournament"), which forces rivals to team up, Dragón Rojo Jr. was paired with La Sombra; they lost to Atlantis and Dorada in the first round on January 22.

Los Guerreros de la Atlantida (2010–2012) On November 2, Dragón Rojo Jr. (replacing an injured Atlantis) and Guerrero defeated Garza and Mr. Águila for the CMLL World Tag Team Championship.

On November 18, Dragón Rojo Jr. defeated Jushin Thunder Liger to win the CMLL World Middleweight Championship, making him a double champion. Throughout 2012, Dragón Rojo Jr. successfully defended his title against Ángel de Oro on January 3, La Sombra on April 30 and May 20, and Titán on July 20. On August 3, he and Guerrero lost the CMLL World Tag Team Championship to Atlantis and Diamante Azul, ending their reign at 640 days. He was again defeated by La Máscara in the first round of the Universal Championship tournament on August 24. On September 28, Rojo Jr. defeated Prince Devitt to win the NWA World Historic Middleweight Championship, making him a double middleweight champion.

Los Revolucionarios del Terror (2012–2021) Following his championship victory, Dragón Rojo Jr. quit Los Guerreros del Infierno, forming a team with Rey Escorpión and Pólvora unveiled as Los Revolucionarios del Terror ("The Revolutionaries of Terror"). He was forced to team up with partner-turned-rival Niebla Roja for the Torneo Nacional de Parejas Increibles on March 8, 2013, defeating El Terrible and Rush in the first round and Blue Panther and Escorpión in the quarter-finals, before losing in the semi-finals to Atlantis and Último Guerrero. At the CMLL 80th Anniversary Show on September 13, Los Revolucionarios del Terror failed to win the CMLL World Trios Championship from Dorada, Místico and Valiente. On June 20, he competed in the Leyenda de Azul ("The Blue Legend") tournament, but was eliminated mid-way through.

On July 9, Dragón Rojo Jr. announced that due to his recent problems with his stablemates, he was leaving Los Revolucionarios del Terror and turning técnico. He successfully defended the CMLL World Middleweight Championship against Escorpión on August 8. During the Universal Championship tournament on August 22, he defeated Virus in the first round, but lost to Guerrero in the quarter-finals. He ended 2014 by successfully defending his title against Pólvora on December 22. In early 2015, Dragón Rojo Jr. feuded with Roja over the title, successfully defending it against him on February 3. They were defeated by El Terrible and Máximo in the first round of the Torneo Nacional de Parejas Increíbles on February 27.

Dragón Rojo Jr. returned to the rudo side on May 8, as he, Escorpión and Pólvora revived Los Revolucionarios del Terror.
