Rey Mysterio, currently serving as AAA General Manager, sparked major speculation during Saturday’s AAA on Fox episode by teasing the upcoming appearance of a “former WWE world champion.” Some fans online initially guessed Alberto Del Rio, but the mystery was solved at the next taping, when attendees on social media shared that former WWE World Heavyweight Champion Damian Priest had delivered an in-ring promo after the live broadcast ended.
WWE Hall of Famer Mysterio was named AAA General Manager on May 23, 2026, in a surprise announcement by President Marisela Peña. Subsequqntly he called the role a dream come true, crediting AAA for giving him his first major television exposure in 1992. Since taking the position, Mysterio has driven major crossovers, including the first NXT Women’s Championship match in Mexico, while blending nostalgia, authority storylines, and star power to help elevate the promotion to a new audience.
