Six WCW superstars collided at Clash of the Champions XXIII in the summer of 1993 as Sting, British Bulldog and Dustin Rhodes battled WCW Champion Big Van Vader, Rick Rude and Sid Vicious in a hard-hitting six-man tag team showdown. The rivalry centred around Vader's WCW World Heavyweight Championship reign and his ongoing feud with Sting and British Bulldog. Sid Vicious had recently returned to WCW and joined forces with Vader, forming the feared "Masters of the Powerbomb" alliance.
