1980s, Hogan was the villain and Roussimoff was the hero, wrestling him at Shea Stadium's third Showdown at Shea event and in Pennsylvania, where after Roussimoff pinned Hogan to win the match, Hogan bodyslammed him much like their legendary WrestleMania III match in 1987. The feud continued in Japan in 1982 and 1983 with their roles reversed and with Antonio Inoki also involved. One of Roussimoff's feuds pitted him against the "Mongolian Giant" Killer Khan. According to the storyline, Khan snapped Roussimoff's ankle during a match on 2 May 1981 in Rochester, New York by leaping off the top rope and crashing down upon it with his knee-drop.

McMahon signed Roussimoff to these terms in 1984, although he still allowed him to work in Japan for New Japan Pro-Wrestling (NJPW). Roussimoff feuded with Big John Studd over which of the two men was the "true giant" of wrestling. Throughout the early to mid-1980s, Roussimoff and Studd fought all over the world, battling to try to determine who the real giant of wrestling was. In 1984, Studd took the feud to a new level when he and partner Ken Patera knocked out Roussimoff during a televised tag-team match and proceeded to cut off his hair. After gaining
