At WrestleMania XIV, Austin defeated Shawn Michaels to become the new WWF World Heavyweight Champion in a match that featured Mike Tyson serving as the special enforcer. Although Tyson had been aligned with Michaels and his stable D-Generation X, Tyson revealed to have been aligned with Austin all along as he personally counted the pinfall and declared Austin the winner. The Undertaker and Kane fought for the first time at this event where The Undertaker won. The following year at WrestleMania XV, Austin defeated The Rock to regain the WWF Championship. The event featured the first of three encounters at WrestleMania between Austin and The Rock in the rivalry of the two most prominent and popular stars of The Attitude Era.
