The following contains spoilers for Friday's AEW Rampage Grand Slam.
The Great Muta appeared during Wednesday’s AEW Rampage Grand Slam tapings.
Muta aided Sting and Darby Allin during their match against Buddy Matthews and Brody King, which will air this Friday. Matthews was about to attack a handcuffed Sting with a baseball bat when Muta arrived, spitting mist in the face of Matthews. This caused Matthews to bump into Julia Hart, who went through a table. Sting picked up the win for his team. After the match, Sting hugged Muta.
Sting and The Great Muta were both longtime rivals and tag team partners in WCW and New Japan Pro Wrestling in the late 80s and early 90. The Great Muta defeated Sting for the WCW Television title back in September of 1989.
Keiji Mutoh is currently on a retirement tour with Pro Wrestling NOAH. His last match under The Great Muta persona will take place on January 23 at Yokohama Arena. It was announced earlier this month that his final match will take place on February 21, 2023 at the Tokyo Dome.
