Curt Hennig
Lawler won the AWA World Heavyweight Championship from Curt Hennig on May 9, 1988. During his reign, Lawler feuded with World Class Championship Wrestling's Champion Kerry Von Erich. He defeated Von Erich on December 15, 1988, at Superclash III to unify the two titles. Soon after, Lawler's issues with Verne Gagne led to his departure from the AWA.
