Becky Lynch had been a babyface since her debut and it was on the October 16 edition of NXT that she confronted Sasha Banks over her attack on Bayley, which led to Sasha responding and telling Becky to look at herself in the mirror and ask herself what she really wants. On the following week, Becky appeared to save Bayley from an in-ring post-match attack from Sasha, only to attack Bayley from behind, turning Becky into a villainess. Since her betrayal, the evil Becky has aligned with Sasha and assisted her in bullying Bayley and fighting against her and NXT Women's Champion Charlotte Flair. Becky defeated Bayley on more than one occasion in recent episodes of NXT, and she has blamed Bayley for her not winning the NXT Women's Championship at NXT Takeover: Rival. Becky was defeated by ally Sasha Banks in the Fatal Four Way match, which also included Bayley and Charlotte, and on the April 1 edition of NXT, Becky declared that she's going after the title, even though Sasha is the champion.
Becky is portrayed as an arrogant, trash-talking villainess on NXT. Her attack on Bayley clearly shows that she's capable of traitorous conduct. Becky was portrayed as an arrogant, trash-talking villainess on NXT. Her attack on Bayley clearly shows that she's capable of traitorous conduct.
In 2018 on SmackDown Live, Becky Lynch turned heel on Charlotte Flair on Summer slam.
