pursue the WWE Championship despite his friendship with Angle. Mr. McMahon became involved in the angle, at first berating Lesnar, who had involved himself in McMahon's rivalry with Zach Gowen, for losing to Angle. This all turned out to be a swerve that came into focus on the August 7 episode of SmackDown!. That night, Lesnar and McMahon were to face each other in a steel cage match with Angle as the special guest referee as per McMahon's orders on the previous week's program. During the match, Lesnar had passed out due to a staged backstage incident and McMahon was set to pin him, but Angle refused to allow McMahon to win that way. As the two men began to argue, Lesnar attacked Angle with an F-5 and kept attacking Angle while McMahon watched and celebrated with him afterward, turning heel once again in the process. At SummerSlam on August 24, Lesnar lost to Angle after submitting to the ankle lock. On the September 18 episode of SmackDown!, Lesnar defeated Angle in an Iron Man match to win his third WWE Championship by a final score of five to four, thus ending their long-standing feud. Lesnar successfully defended his newly won title against the debuting Paul London on the October 9 episode of SmackDown!. He returned to feud with The Undertaker, as Lesnar had previously cost Undertaker the title in a match against then-champion Kurt Angle on the September 4 episode of SmackDown!, which granted him a shot at Lesnar's title. At No Mercy on October 19, Lesnar defeated Undertaker in a Biker Chain match after interference from The Full Blooded Italians and Vince McMahon. After Paul Heyman returned to WWE as SmackDown! General Manager, Lesnar aligned himself with Heyman. With Survivor Series coming up, he challenged Angle to a traditional Survivor Series elimination tag team match. Lesnar chose Big Show as his first teammate, with Heyman adding a returning Nathan Jones and a debuting Matt Morgan to bring the team number to four. Angle chose Chris Benoit and The APA (Bradshaw and Faarooq) to join his team. Faarooq was injured during a match with Lesnar and Angle's team was forced to find a replacement for him. Lesnar's team picked A-Train to fill the fifth and final spot for them after he attacked John Cena, who refused to accept an invitation to join Lesnar's team. Cena instead joined Angle's team
