SummerSlam (2002)
The main event was for the WWE Undisputed Championship between The Rock and Brock Lesnar. Lesnar dominated early with some power moves. The Rock went for the Sharpshooter. Lesnar's manager Paul Heyman got involved in the match, as he was attacked by The Rock, who executed a Rock Bottom through a broadcast table on Heyman. The Rock and Brock Lesnar gave each other a "Rock Bottom". The match came to an end when Lesnar stopped a People's Elbow and a "Rock Bottom" and then executed the "F-5" on The Rock for the win and the title. Lesnar remained the youngest world champion in WWE history until Randy Orton won the World Heavyweight Championship in 2004, although Lesnar remains the youngest WWE Champion in history.

When he returned, The Rock won the WWE Undisputed Championship at Vengeance on July 21, defeating Kurt Angle and The Undertaker in a triple threat match. The Rock successfully defended the title at Global Warning in Australia against Triple H and Brock Lesnar by pinning Triple H, who saved The Rock when Lesnar attacked him after the match. At SummerSlam on August 25, after interference from Lesnar's manager Paul Heyman and the use of a steel chair, The Rock lost the WWE Championship to Lesnar along with the record for the youngest WWE Champion, which he had set in 1998. In 2018, writing for "ESPN.com", Sean Coyle noted in a retrospective review of the event, that following his victory over Hogan at WrestleMania X8, "The Rock started to see a dip in fan support" and "that dip turned into a plunge in fan support by the time SummerSlam rolled around", because the fans knew his career was headed to Hollywood, as he was met with a negative crowd response during his match against Lesnar. After the event ended, The Rock was visibly angry at the crowd reaction. When he tried to do a post-show speech for the crowd, the fans attending the Nassau Coliseum would still boo him. He eventually cut a promo, declaring that he will still be "The People's Champion", whether the audience likes it or not, and that "sing-along with The Rock is over", before taking a sabbatical from wrestling in order to focus on his film career.
