On December 5 at Guerra de Titanes L.A. Park defeated El Mesías to become the number one contender to the AAA Mega Championship, though, at the same event his La Sociedad stable mate El Zorro became the new champion by defeating Dr. Wagner Jr. In February 2011 the next title shot was awarded to Charly Manson to set up a grudge match between him and El Zorro, causing dissension between Park and Konnan. On February 28 Park entered the 2011 Rey de Reyes tournament in order to solidify his spot as the number one contender, defeating Dr. Wagner Jr., Halloween and Nicho el Millonario in his semifinal match. During the match Park was attacked by La Sociedad member Damián 666, who was seemingly trying to prevent him from advancing in the tournament, but instead the interference distracted Wagner Jr. and cost him the match. On March 18 at the Rey de Reyes pay-per-view, Park was eliminated from the finals of the tournament, after brawling with rival El Mesías to a double countout.

On May 18, Park accepted El Mesías' challenge for a Mask vs. Hair match at Triplemanía XIX. Park added to the stakes of the match by announcing that he would retire, should he lose his mask. On June 18 at Triplemanía XIX, Park defeated El Mesías, forcing him to have his head shaved. On July 31 at Verano de Escándalo, Park faced La Sociedad stablemate and new AAA Mega Champion Jeff Jarrett and Dr. Wagner Jr. in a three-way match for the title, with Konnan stating that Park's job was to ensure that the title stayed with Jarrett. After Wagner Jr. was eliminated from the match, Jarrett pinned Park to retain his title, when someone masked as El Zorro interfered and hit him with a guitar. This person was later revealed as La Sociedad member Chessman, whom Konnan had sent to
