Slaughter's career took off after he turned face and defended America's honor against the hated Iron Sheik. Slaughter and the Iron Sheik engaged in many matches throughout the year, culminating in a boot camp match that took place before a sold-out Madison Square Garden that summer. However, with the emergence of Hulk Hogan as the WWF World Heavyweight Champion and lead face within the company, Slaughter left for the AWA. On Vince McMahon's McMahon DVD, Slaughter said he was fired by McMahon in Toronto after no-showing an event in protest of McMahon's refusal to give him six weeks of paid vacation. Other interviews with Slaughter and McMahon have revealed that Slaughter left the company more over a dispute that emerged due to the WWF not allowing Slaughter's role in the G.I. Joe toy line. At the time of his departure Slaughter was easily the second biggest "face" in the company, surpassing Jimmy Snuka, and even André the Giant, with his popularity rivaling that of Hulk Hogan's.

He defended the title against wrestlers like Zbyszko, Kamala, Boris Zukhov, and Nick Bockwinkel (before the belt was retired) and feuded with Sheik Adnan Al-Kaissey and his stable of wrestlers, The Road Warriors, and Colonel DeBeers. He even challenged Stan Hansen for the AWA title. He was also involved in the short-lived Pro Wrestling USA Promotion. This was a brief attempt at pulling together the remaining wrestling talent to go up against the rising WWF. Slaughter in this company won a large 25-man battle royal by eliminating Kamala, winning the right to challenge Ric Flair for the NWA World Heavyweight Championship. In 1988, Slaughter returned to wrestling in the AWA, resuming some of his past feuds with the likes of Sheik Adnan Al-Kaissey, the Iron Sheik, and Col. DeBeers. He also became a top contender to the AWA World title during Larry Zbyszko's reign in 1989 and was a team captain for the AWA's ill-fated Team Challenge Series during the first half
