After Colón defeated Flair, he would go on several undefeated streaks; this lasted until Funk "injured" him in a match. This event led to the championship being vacated for the first time. He subsequently competed in a tournament to determine the new champion where he won it for a fifth time. After this he was involved in an angle where Hercules Ayala turned on him and won the championship. This led to the organization of several matches, before he won it on a rematch. Sadistic Steve Strong was the next champion, upon his entrance to the company he was billed as a "satanic heel".

González won the match and became the champion in an unexpected result. González wasn't well received as a face and subsequently lost the championship to Dutch Mantel on June 22, 1994. This led to an angle between Mantel and Colón, who won the championship a sixteenth time. He was subsequently involved in a feud with Mabel, in which both wrestlers had a reign, which Colón eventually ended with Abdullah the Butcher winning the championship and engaging in a feud with Bronco, who won
