The two top stars of the Attitude Era, Stone Cold Steve Austin and The Rock, eventually left the company in 2003 and 2004 respectively, while newcomers such as Brock Lesnar, who would become the youngest WWE Champion and Randy Orton, who became the youngest World Heavyweight Champion, saw huge success. Triple H would also be featured prominently during this time, winning several of his fourteen world championships, as would The Undertaker, whose WrestleMania win streak started gaining fame. Eddie Guerrero, Rey Mysterio, Kurt Angle, Chris Benoit, Edge, Brock Lesnar, Randy Orton, John Cena, Batista, John "Bradshaw" Layfield, and Rob Van Dam were also given main event opportunities and all ended up becoming multiple-time world champions. From mid 2002 to 2003, WWE brought several prominent WCW stars to the company, including Eric Bischoff, Scott Steiner, Goldberg, Kevin Nash and Ric Flair. The Great American Bash, originally a WCW pay-per-view event, made its debut in WWE.
