Knockout is a term used by Total Nonstop Action Wrestling (TNA) to refer to its female talent. The term is applied universally to wrestlers, backstage interviewers, and managers/valets.
The term Knockouts is relatively new and was not used when Total Nonstop Action Wrestling debuted in 2002. The name originated from a DVD release in 2006 by the company, Knockouts: The Ladies of TNA Wrestling, Vol.1, which focused on its then-current female stars. The name "Knockouts" as a catchall name for the women stuck after that. Female performers have been a part of TNA since the first national show, which featured Alexis Laree, Elektra, , Francine, Miss Joni, Sasha, Shannon, Taylor Vaughn and Teresa Tyler, as well as other female talent, including backstage interviewer Goldy Locks and valets Aleesha and Fluff Dupp. Bobcat also debuted as a valet in a match that was taped during the first PPV, but aired during the second PPV.
A Lingerie Battle Royal to crown the first 'Miss TNA' was taped during the very first NWA:TNA weekly PPV on June 19, 2002, and was aired during the second PPV on June 26, 2002.Taylor Vaughn won the first Miss TNA crown. She defended the title against Francine, who soon afterward abandoned her pursuit of the title and engaged in a brief feud with Jasmin St. Claire. Vaughn lost the title when she was defeated by male character Bruce a few weeks later. Although male, he claimed that he should be entitled to wrestle for the Miss TNA crown because he was gay. Bruce held the crown for three months and during his time as Miss TNA he attacked many female wrestlers and fans, enraging the male stars of TNA including Jorge Estrada. The two then had a singles match with the stipulation that if Estrada won, Priscilla would become the new Miss TNA. Although Estrada won the match, the crown didn't change hands because he won by disqualification. In the next weeks, Bruce's tag team partner, Lenny, tried to get Bruce injured (since the runner-up would then take over the crown should the champion be injured). This led to the breakup of The Rainbow Express, and Bruce's homosexuality was questioned by backstage interviewer Goldy Locks, who claimed she had seen him in the shower with April Pennington. The storyline soon came to a close due to poor crowd reception, with Pennington and Goldylocks walking off together holding hands, as Lenny and Bruce fought over Pennington. The storyline ended with Bruce declaring himself straight and handing his crown over to Pennington. The Miss TNA crown wasn't mentioned on-screen afterward. Throughout 2002, TNA also featured Belladonna in a valet role and former WWE Tough Enough contestant Paulina as a bodyguard.
