Apolo Estrada Jr. is the ring name of Roberto Guadalupe Estrada Zúñiga (born January 10, 1987), a Mexican luchador or professional wrestler. He is the son of professional wrestler Apolo Estrada and has worked for Consejo Mundial de Lucha Libre (CMLL), International Wrestling Revolution Group (IWRG) as well as working for many professional wrestling promotions on the Mexican independent circuit. From 2009 to 2015 he was a member of a wrestling group known as Los Gringos VIP and currently forms a team known as Los Insportables with Eterno.
 Roberto Estrada began his professional wrestling career in 2000, working as the enmascarado character El Chupacabras. Estrada was around 13 years old when he wrestled his first match, something that is not unheard of in Lucha Libre
 By 2003 he began working regularly in Monterrey, now unmasked and billed as Apolo Estrada Jr. for Federacion Internacional de Lucha Libre. Over the next five years Estrada Jr. was a regular worker for the promotion, holding a number of different championships, often teaming with Estrella Dorada Jr. During his time in Monterrey he competed in a number of Luchas de Apuestas, or bet matches, the most prestigious match type in Mexico.
He won the hair of Crazzy Demon, Androide, Potro Jr. and Gato Volador as well as the mask of Black Gordman Jr. By the same token he also lost several match and as a result was shaved bald after losing to long time partner/rival Estrella Dorada Jr. as well as Corazo de Barrior and Hombre Sin Miedo.
 In 2009 Estrada Jr. began working for Consejo Mundial de Lucha Libre (CMLL) as a low ranked rudo (those that portray the "bad guys"). The highlight of his time in CMLL was a ten-man steel cage match where Apolo Estrada Jr. defeated Brazo de Platino in the end, forcing Brazo de Platino to be shaved bald as a result.
 Estrada left CMLL in late 2010 and began working for a variety of promotions on Mexico's independent circuit, including making regular appearances for International Wrestling Revolution Group IWRG.
 In late 2011 the group known as Los Gringos Locos (El Hijo del Diablo, Avisman and Gringo Loco) held the Distrito Federal Trios Championship when Gringo Loco left Mexico and stopped working for IWRG. The Mexico City wrestling commission allowed IWRG to substitute Gringo Loco with Apolo Estrada Jr. to carry on the Distrito Federal Trios Championship. The group would later be renamed Los Gringos VIP as they held the Trios title for over a year, until March 19, 2012. The trio regained the championship in September, 2013. With Gringos VIP partner El Hijo del Diablo Estrada Jr. won the IWRG Intercontinental Tag Team Championship on May 21, 2015 as they defeated Alan Extreme and Veneno to win the titles. Their run with the tag team championship lasted only 25 days until IWRG decided to move the titles over to Los Oficiales (Oficial 911 and Oficial AK-47) instead. Estrada Jr. also held the WWS World Welterweight Championship, a title promoted by IWRG, as he defeated Dr. Cerebro to win the vacant title on December 8, 2013. Dr. Cerebro would later win the title from Estrada Jr. On August 14, 2015 Los Terribles Cerebros (Black Terry, Dr. Cerebro and Cerebro Negro) won the Distrito Federal Trios titles from Los Gringos VIP, ending their reign after 643 days. Los Gringos VIP, in this instance Apolo Estrada Jr. and El Hijo del Diablo, defeated Los Panteras (Pantera and El Hijo del Pantera) to win the IWRG Intercontinental Tag Team Championship for the second time. Their title reign lasted 67 days until Los Panteras regained the championship. After the title loss Estrada Jr. and Hijo del Diablo attacked each other, blaming the other for the loss and ending the Los Gringos VIP faction.
 In the week following the break up of Los Gringos VIP Apolo Estrada Jr. began teaming regularly with Eterno, forming a tag team known as Los Insoportables ("The Unsupportable Ones"). As part of the team Apolo Estrada Jr. often supported Eterno as Eterno feuded with Black Terry. Los Insoportables are scheduled to put their hair on the line in the main event of the Arena Naucalpan 38th Anniversary Show, facing off against the Terribles Cerebroros team of Black Terry and Dr. Cerebro.
