The Warrior received a push as WWF's main event successor to Hulk Hogan, who had remained wrestling's biggest star throughout the 1980s. Following a few confrontations with Hogan, most notably at the 1990 Royal Rumble, the Warrior was written in as Hogan's opponent in the main event for WrestleMania VI at the SkyDome in Toronto. The match was billed as "The Ultimate Challenge", as both Hogan's WWF World Heavyweight Championship and Warrior's Intercontinental Heavyweight Championship were on the line. Warrior pinned Hogan after a Warrior Splash to become the only wrestler to hold both championships simultaneously. Warrior vacated the Intercontinental Championship (which Mr. Perfect then won in a tournament), as WWF rules prohibited a wrestler from holding both titles.
