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.
SummerSlam (2011)
The main event from the Raw brand for SummerSlam would pit John Cena against CM Punk for the WWE Championship. In the weeks leading to the Money in the Bank pay-per-view in July on "Raw", Punk announced the expiry of his WWE contract on the night of the July 17, 2011 event, en route lambasting WWE for failing to promote him as the "best wrestler in the world", and threatened some high authority figures like WWE Chairman, Vince McMahon, of defeating Cena and leaving WWE with the championship. At Money in the Bank, Punk pinned Cena to win the title, and even after McMahon tried to have Alberto Del Rio – who had won the Raw Money in the Bank briefcase earlier that night – cash in his contract against Punk. The latter nevertheless left the arena with the championship. The following night on "Raw", McMahon dismissed Punk's claim to the title, and announced an 8-man tournament to decide the new WWE Champion. Also, on the same night, Triple H relieved McMahon of his duties, and assumed control over WWE as the Chief Operating Officer. On the edition of July 25, 2011 of "Raw", Rey Mysterio defeated The Miz in the finals to become the WWE Champion but lost it later on the same night against Cena. After the match, Punk returned to WWE with the title belt he had won at Money in the Bank. As they were now two wrestlers with a claim to the WWE Championship, a one-on-one match between Punk and Cena was scheduled for SummerSlam to determine the undisputed WWE Champion. On August 8, 2011 episode of "Raw", Triple H made himself the special guest referee for the Undisputed WWE Championship match.
