#1 Becky Lynch
Becky Lynch has progressed exponentially since changing her character. At WWE Evolution, Lynch successfully retained the SmackDown Women's championship against Charlotte. After her victory, Lynch began using the moniker, The Man, (watch the video below). Since then her performance has been excellent.
Whether battling comments on her Twitter feed or in the ring, Lynch seems unstoppable. Although an excellent performer throughout her career, it is her current character which shines through. Moreover, it cements the aura of WWE women's wrestling. Ultimately, Lynch has become a mainstay element within WWE.
Considering AEW lurking behind the scenes, WWE must change their direction. With Lynch's extreme popularity she draws revenue anywhere she performs. Will Lynch become synonymous with WWE, like past stars Hulk Hogan, John Cena, or CM Punk? She certainly has the credentials. Moreover, it would be an epic way to battle AEW.
