As Victoria, she started out as a psychotic villainess who wanted revenge on Trish Stratus, who (in her mind) betrayed her back when they were fitness models together by leaving her to join WWE. Her first heel role led to her first Women's Championship victory over Trish. Victoria's second run as a villainess began in 2005 after she attacked all of the participants of a bikini contest, which was won by Christy Hemme. After the attack, the evil Victoria explained her actions by expressing jealousy of Christy's popularity, which led to a short feud that ended with Victoria defeating Christy at Vengeance. Months later, Victoria aligned with fellow villains Torrie Wilson and Candice Michelle as they tormented Ashley Massaro, as well as Trish Stratus and Mickie James. Victoria's second heel role lasted until she left WWE in January 2009.
Varon joined TNA as Tara in May 2009 as a face, but she would turn into a heel Knockout in 2010 when she attacked her tag team partner, Angelina Love, after they lost to Madison Rayne and Velvet Sky in a tag team bout for the Knockouts singles and tag team championships. Tara would later align with Madison Rayne as the two continuously battled against Mickie James for several months. That heel stint came to an end when Tara was freed from Rayne's control due to James defeating her in May 2011. Despite her babyface run at the time, Tara portrayed a villainous opponent for Gut Check contest Taeler Hendrix. After defeating her, Tara went back to her babyface role and hugged Taeler in a show of respect.
Tara would become a villainess again four days after she was unsuccessful in defeating her protégé, Brooke Tessmacher, for the Knockouts Championship at No Surrender; doing so by attacking Brooke in the ring. After the heel turn, the evil Tara nearly attacked Christy Hemme when she refused to say that she (Tara) was her favorite Knockout. Tara won the Knockouts Championship from Brooke at Bound For Glory, and she revealed her "Hollywood Boyfriend" as Jesse Godderz that same night. Tara's last stint as a villainess ended when she left TNA in mid-2013.
