 Lesnar 's next opponent was Big Show . Heyman was convinced more than anyone that Lesnar could not win , trying to talk him out of defending the title . Lesnar refused and faced Big Show in Madison Square Garden at the Survivor Series pay @-@ per @-@ view . Towards the end of the match , Lesnar delivered an F @-@ 5 to Big Show , but when he went for the pin , Heyman pulled the referee out of the ring . This allowed Big Show to capitalize and proceeded to chokeslam Lesnar on a steel chair . Show went on to pin Lesnar and win the title . This loss was Lesnar 's first pinfall loss in WWE and led Lesnar to turn for the first time in his career into a fan favorite . Following Survivor Series , Heyman made it clear that Lesnar would not get a rematch , and had snuck a special clause saying so into his contract . In order to gain his revenge on Big Show and Heyman , Lesnar interfered in his first title defense , which came against Kurt Angle the next month at Armageddon . Lesnar hit the F @-@ 5 on the champion , which enabled Angle to pin him and win the title . On the following episode of SmackDown ! , however , Angle introduced Heyman as his manager and , despite promising Lesnar a title shot earlier in the evening , declared that Lesnar still would not get it . Lesnar was beaten down by Big Show and Angle after the main event , but would get his revenge after the show went off the air . He eventually knocked the Big Show out with a steel chair , leaving Angle alone with Lesnar . Lesnar then chased the champion out of the ring and resumed his assault that culminated when Lesnar used the F @-@ 5 to propel Angle 's right knee into the steel ringpost . As paramedics tended to a screaming Angle , Lesnar finished off the assault with a <unk> on the ringside barricade , breaking the champion 's leg in storyline .
