They feuded with the Dudes With Attitudes which consisted of Sting, Luger, the Steiner Brothers, Paul Orndorff and Junkyard Dog. By the end of 1990, Ole and Woman left the NWA. In October 1990, NWA World Champion Sting defended his title against the Horsemen's Sid Vicious at the Halloween Havoc pay-per-view. During the match, Sting and Vicious brawled backstage. A few moments later, they returned to the ring. Sting attempted to slam Sid, but lost his balance and fell to the mat with Sid on top of him. Vicious got the pin and was declared the new World Heavyweight Champion. However, it was revealed that Barry Windham (in matching Sting gear and face paint) had inserted himself into the match and let Vicious pin him. When the real Sting showed up, the match was restarted and the real Sting defeated Sid to retain the title. The Horsemen line-up of Flair, Anderson, Windham, and Vicious eventually broke up and went their own ways. In May 1991, Sid left for the WWF. Flair was fired from WCW in early July and was in the WWF by August. Windham was part of a double turn at The Great American Bash shortly after Flair's firing, where he lost to Lex Luger in a match for the vacant WCW world championship (Windham became a face, Luger a heel). Anderson went on to form a tag team with Larry Zbyszko called The Enforcers and later became part of the Paul E. Dangerously-led Dangerous Alliance with Zbyszko, Rick Rude, Madusa, Bobby Eaton, and Steve Austin. Anderson and Windham feuded during this time, beginning with an incident at Halloween Havoc where Arn and Zbyszko slammed a car door on Windham's hand. Three Horsemen (May 1993 – December 1993) The next incarnation of the Horsemen, containing only three active members, was around for less than 7 months in 1993. Flair returned from the WWF to WCW to rejoin Arn and they promised a Horsemen reunion at the Slamboree pay-per-view. Paul Roma became the third horseman after Tully Blanchard and WCW could not come to terms on a deal for him to return. Ole Anderson was on hand as the adviser but made only one appearance on A Flair for the Gold. This group of Horsemen is considered by many wrestling fans to be the weakest incarnation of the group. They were faces again and feuded with Barry Windham and
