Dr. Wagner
Dr. Wagner Jr. had made a surprise appearance at the 2009 Rey de Reyes show, making his debut after the main event where he challenged El Mesías for a shot at the AAA Mega Championship. Konnan tried to convince Dr. Wagner Jr. to join "La Legión", even suspending him for two weeks so he could "make up his mind". In actuality this was done to cover up the fact that Dr. Wagner Jr. still had booking responsibilities to take care off before he could work for AAA full-time. In the lead up to Triplemanía XVII Dr. Wagner Jr. and El Mesías teamed up to wrestle against "La Legión", showing unity and respect for each other. The Triplemanía XVII match would be their first match against each other.
