Lesnar debuted on WWF television on the March 18, 2002, episode of "Raw" as a heel, attacking Al Snow, Maven and Spike Dudley during their Hardcore Championship match, while also being accompanied by Paul Heyman, who was seen giving instructions to Lesnar. When the brand extension was introduced in the WWF, Lesnar was drafted to the Raw brand. Later, Heyman was confirmed to be Lesnar's agent and gave Lesnar the nickname "The Next Big Thing". Lesnar's first feud was with The Hardy Boyz and Lesnar defeated Jeff Hardy by knockout after Hardy was unable to respond to referee Theodore Long at Backlash on April 21, his first official televised match. The next night on "Raw", Lesnar faced off against Jeff's brother, Matt Hardy, and defeated him in the same fashion. Lesnar and Shawn Stasiak lost to The Hardy Boyz at Insurrextion on May 4 after Stasiak was pinned, but he attacked all the participants after the match. At Judgment Day on May 19, Lesnar and Heyman defeated The Hardy Boyz.
