Wrestlemania 7... but the outcome is affected by the opponent. Should never have been Slaughter but Rick Rude - and Hogan should have lost.
Except that Hogan outweighed Rude by a 100 pounds lol. I personally liked the angle with Slaughter. It was one of the greatest heel turns of all time and brought out raw emotion from fans. Too bad it didn't happen closer to Slaughter's prime. By 1990, his best days were done.
Rude left the company because he was paid substantially less than Warrior for SummerSlam '90 despite carrying the match. He was scheduled to feud with Boss Man next so a match with Hogan was never in the cards. Hogan and Rude did have some house show matches in the mid-'80's I believe around 1987.
