In the aftermath of the Invasion angle, the WWF made several major changes to their product. Ric Flair returned to the company as a "co-owner" in storylines, feuding with Vince McMahon. Jerry "The King" Lawler returned to the RAW broadcast booth, after quitting earlier in the year. Several former Alliance stars were absorbed into the regular WWF roster, such as Booker T, The Hurricane, Lance Storm, and Rob Van Dam. Steve Austin's run as a heel was over, as he was accepted by the fans again as a babyface. And, for the first time ever, the WWF was left with two heavyweight champions. The Rock held the WCW Title while Austin held the WWF title. It was decided that a mini-tournament would be held at the Vengeance 2001 pay-per-view, consisting of Austin, the Rock, Chris Jericho, and Kurt Angle. The winner of that tournament would hold both titles. Jericho came out the victor that night, defeating both the Rock and Austin. This made Jericho the first WWF Undisputed Champion.
