Los Boricuas was a stable that materialized in the World Wrestling Federation (WWF) in 1997. Savio Vega formed the stable after he was expelled from the Nation of Domination. The group made its television debut in June 1997. The son of Miguel Pérez, Miguel Perez, Jr. joined the faction. José Estrada, Jr. was the son of former WWF Junior Heavyweight Champion José Estrada. Jesús Castillo was a second-generation wrestler himself. They were mainly involved in angles with other stables including the Nation of Domination and the Disciples of Apocalypse. During WrestleMania XIV's tag team battle royal, Los Boricuas engaged two teams (Savio and Miguel, and José and Jesús), fighting on Raw is War. Vega left the group in July and would return to a singles career before being released later that summer after suffering an arm injury during the Brawl for All tournament. Castillo, still a team member, became a jobber on Shotgun. Perez, Castillo and Estrada would still fight as a tag team on Raw is War and Shotgun until October 1998, and competed on Super Astros until the show ended in September 1999 and all three of them left the company. Their final match as a group took place on the August 29 episode of Super Astros, where Savio Vega returned to WWF as their manager and managed them to a win against Papi Chulo, Pantera and Apolo Dantés. On September 5, 1999, Los Boricuas made their final appearance in a backstage segment, which was the last episode of Super Astros.
