Aside from its record-breaking attendance record, the event is arguably best remembered for "The Ultimate Challenge" - the main event match which saw Hulk Hogan (WWF Champion) vs The Ultimate Warrior (WWF Intercontinental Champion), in which both championship titles were on the line. On February 3, 1990, a week after Hogan and Warrior crossed paths in the 1990 Royal Rumble Match, Hogan put forth "The Ultimate Challenge" to the Warrior, and had to know whether Hulkamania or the power of the Warrior was the strongest force in the World Wrestling Federation. On February 10, the match was officially announced as the main event of WrestleMania VI by WWF President Jack Tunney. On February 24, Tunney announced that both the WWF Championship and Intercontinental Championship would be on the line for the first-time ever during the match.
At WrestleMania VI, Brutus "The Barber" Beefcake was the first person to pin Mr. Perfect in a televised match, thus ending Perfect's lengthy undefeated streak on TV. Hennig had actually been beaten on house shows before WrestleMania, as the announcers said nothing about his "perfect record" during the match.
