Pérez followed this with a feud against Dennis Rivera, with the first two matches being ruled no contests before both exchanged victories. Los Boricuas then entered a rivalry with Joe Bravo and his stable. Pérez defeated both Bravo and his henchman Joan Manuel "El Bacano" Almonte, but failed to capute the IWA Undisputed World Heavyweight Championship from Bravo. In their next encounter, Los Boricuas came on the winning side of a match involving all four of them. This storyline continued during the IWA's 10th Anniversary celebrations, in which they teamed with several former IWA wrestlers to defeat the whole "La Revolución" stable, repeating this result in two subsequent events. Concurrently, the "Faraón Zaruxx" mantle was passed on to another wrestler. On August 29, 2009, Pérez defeated Bravo to win his first Undisputed World Heavyweight Championship. He was successful in his first defense over Almonte. Los Boricuas reunited one last time to defeat La Revolución. Pérez picked two more defenses, before dropping the title to Bravo. One week later, he defeated Rondón in a singles match. On November 1, 2009, Pérez and Vega participated in a Dominican Wrestling Entertainment card, being booked to win the DWE World Tag Team Championship. Los Boricuas held the championships until the promotion's final event of the year. Shortly afterwards, Pérez announced his retirement as an active wrestler, instead remaining involved in administrative issues. Late career (2009–present) Following Hardcore Weekend 2011, a group of unnamed wrestlers began pestering him in random public places as well as assaulting the IWA Champions during events. When confronting them, they identified as "The Academy", led by Chris Angel and Phillip Davian, citing that they only wanted a chance to "bring forth a change needed by the IWA". Pérez unexpectedly reacted by offering them contracts, citing that he actually wanted a change himself, even granting them championship bouts at Christmas in PR 2011. In this event, Rivera became Angel's opponent for the vacant Intercontinental Championship, losing the contest. Rivera demanded a rematch, but Pérez considered it too risky, grudgingly accepting sanctioning it. When Angel retained in a rematch, Pérez intercepted Rivera upon exiting the ring, telling him not to return to the IWA until he became reacquainted with his "roots". Pérez reappeared at Summer Attitude, confronting Rivera after WWC wrestlers counterattacked IWA due an invasion led by him, ruining Víctor Quiñones' Hall of Fame induction, claiming that he didn't meant those
