Lesnar returned on the January 28, 2013, episode of "Raw", confronting Mr. McMahon who was about to fire Heyman, and despite Heyman's pleas, Lesnar attacked McMahon with an "F-5", breaking McMahon's pelvis in storyline. The following week during The Miz's "Miz TV" talk show, "Raw" Managing Supervisor Vickie Guerrero revealed herself as the one who signed Lesnar to a new contract to impress McMahon. On the February 25 episode of "Raw", Lesnar once again attempted to attack McMahon, only to get into a brawl with the returning Triple H, which resulted in Lesnar legitimately having his head split open and requiring eighteen stitches. The following week on "Raw", Triple H issued a challenge to Lesnar, requesting a rematch with him at WrestleMania 29, which Lesnar accepted but only after Triple H signed a contract and Lesnar named the stipulation. After Triple H signed the contract and assaulted Heyman, the stipulation was revealed as No Holds Barred with Triple H's career on the line. At WrestleMania on April 7, Lesnar lost to Triple H after a "Pedigree" onto the steel steps. On the April 15 episode of "Raw", Lesnar attacked 3MB (Heath Slater, Drew McIntyre, and Jinder Mahal) before Heyman challenged Triple H to face Lesnar in a steel cage match at Extreme Rules, which Triple H accepted the following week. At Extreme Rules on May 19, after interference from Heyman, Lesnar defeated Triple H to end their feud. Lesnar returned on the June 17 episode of "Raw", attacking Heyman's fellow client CM Punk with an "F-5". Despite the accusations from Punk, Heyman claimed that he was not behind Lesnar's attack on him. However, Heyman turned on Punk in July, and claimed that Punk could not beat Lesnar, which led to Lesnar making his return and attacking Punk on the July 15 episode of "Raw". The following week on "Raw", Punk challenged Lesnar to a match at SummerSlam on August 18, where Lesnar defeated Punk in a no disqualification match.
