Shortly after Carly Colón signed with WWE, a tournament was organized to determine the new champion. Colón was considered an early favorite and reached the final, but lost. Colón then entered a feud with El Diamante over the WWC Puerto Rico Heavyweight Championship. In late 2004, Colón was involved in a battle royal for the first contender's position. One week later on November 6, 2004, Colón defeated El Bronco and won the Universal Heavyweight Championship for the first time in his career. He then entered a feud with El Diamante, eventually dropping the title to him. On July 31, 2005, he formed a tag team with his father as part of the Funking Conservatory‘s television show, !Bang!, competing against Dory Funk, Jr. and Johnny Magnum. The team was victorious, winning the promotion’s Television Tag Team Championship. On March 5, 2006, he participated in WCW Saturday Night tribute show World Wrestling Legends: 6:05 - The Reunion, he was defeated by Vampiro. On July 13, 2007 at World Wrestling Council’s anniversary event, ‘’Aniversario 2007’', Colón wrestled Christian Cage in a match that resulted in a double-countout.
