At Triplemania XVII, El Zorro turned on the Legion during the main event of the show. El Zorro came out wearing his old mask, handed Joaquin Roldan his kendo stick to help him keep Konnan from interfering in the main event. Keeping Konnan from interfering helped Roldan's Team AAA to win the match and take control of AAA away from the Legion. In October El Zorro once again turned rudo and re-joined La Legion Extranjera. In the summer of 2010 La Legión Extranjera merged with Los Perros del Mal, La Milicia and Los Maniacos to form La Sociedad. Afterwards, El Zorro, teaming with his Legión stablemate Hernandez, began feuding with La Hermandad 187 (Nicho el Millonario and Joe Líder). On September 14 El Zorro and Hernandez defeated La Hermandad 187 via disqualification and afterwards beat them down, injuring Nicho and ruining his and Líder's upcoming rematch for the AAA World Tag Team Championship. The feud came to an end on October 30, 2010, when El Zorro defeated Nicho in a Lucha de Apuesta weapons match to take his hair. After spending years working as a midcard talent, El Zorro was placed in a main event storyline in November 2010, when he teamed up with technico and AAA Mega Champion Dr. Wagner, Jr. in the 2010 Lucha Libre Premier parejas increibles tournament. After reaching the semifinals of the tournament, El Zorro turned on Wagner, Jr. and challenged him to a match for the World Heavyweight Championship at Guerra de Titanes. On November 28 El Zorro, Dr. Wagner, Jr., El Mesías and Electroshock faced each other in the Lucha Libre Premier semifinal four-way match. After eliminating Electroshock and Wagner, Jr., El Zorro and El Mesías faced each other in the final match, with El Mesías coming out victorious. In the days leading up to Guerra de Titanes, El Zorro made another prophecy, saying that he was going to leave the event with the AAA Mega Championship. On December 5 at Guerra de Titanes El Zorro defeated Dr. Wagner, Jr. with help from his La Sociedad stable mates to win the AAA Mega Championship for the first time. In January 2011, Martínez confirmed that he had signed a two-year non-exclusive contract with American promotion Total Nonstop Action Wrestling (TNA), with whom AAA had a working relationship with, and was just waiting for a start date with the promotion. He, however, never made his debut for TNA. El Zorro made his first title defense on March 18, 2011, at Rey de Reyes, defeating Los Bizarros member Charly Manson, who had recently been tormenting him by hinting at a return of the iron mask. Meanwhile, El Zorro's La Sociedad stablemate L.A. Park had earned himself a shot at the AAA Mega Championship, but Konnan, wanting to avoid dissension within his group, denied him his shot and instead named Manson the number one contender at Rey de Reyes. Following the event, El Zorro, having caught wind of Park's intention of going for his title, seemingly started interfering in Park's matches under his old mask, costing him back–to–back multi–man tag team matches at the April 27 and 30 TV tapings. On May 18, the rest of La Sociedad turned on El Zorro, after which Konnan announced that his new business partner, TNA founder Jeff Jarrett, would be challenging for his title at Triplemanía XIX. It was later revealed that the man who had attacked Park under El Zorro's mask was actually Charly Manson, who had been sent by Cibernético to cause dissension within the ranks of La Sociedad.
