Dr. Wagner
Dr. Wagner Jr. returned to AAA in the fall, shortly after leaving CMLL, as he turned on former tag team partner Rey Mysterio Jr. On August 28, 2016, at "Triplemanía XXIV", Wagner fought against El Texano Jr. and Brian Cage for the AAA Mega Championship, but did not win the championship. During the main event of the show, he disrupted a "Luchas de Apuestas" match between Psycho Clown and Pagano, attacking Psycho Clown. After the match, which Psycho Cown won, Dr. Wagner Jr. challenged Psycho Clown to put his mask on the line in a "Lucha de Apuestas" at "Triplemanía XXV" in 2017, a challenge that Psycho Clown accepted. At "Héroes Inmortales X" Dr. Wagner Jr. defeated Psycho Clown in a match that also included Pagano after Psycho Clown's long time tag team partners, Monster Clown and Murder Clown, turned on him and helped Dr. Wagner Jr. win the match.
