The Invasion (professional wrestling)
Test won the Immunity Battle Royal, which granted him immunity from being fired for an entire year, beginning a storyline in which he would bully other wrestlers simply because he could.  Every Alliance member who held championships were also immune from being fired, such as Christian, the Dudley Boyz, and Rob Van Dam.  William Regal got his job back by being the first to join Vince McMahon's infamous Kiss My Ass Club.  The remaining Alliance members (with the exception of RVD) would associate themselves with Vince, who immediately turned heel, against Austin, who immediately turned face.  Kurt Angle remained a heel, despite being the one responsible for the end of the Alliance.  It was during this storyline that Stone Cold Steve Austin coined the "What?" catchphrase, which fans continue to chant to this day.  Ric Flair would make a return and become the kayfabe co-owner of the WWE with Vince.
