#4 Charlotte Flair
Charlotte Flair is just a natural heel and somehow has not transitioned into a babyface role very well. She was so much better when she was on RAW, making history for the women's division with numerous outstanding matches against Sasha Banks. Ever since she made her way to SmackDown Live as a babyface, she's been a shadow of that character.
WWE has a chance to strike gold by booking a feud between a heel Charlotte Flair and a babyface Becky Lynch. Maybe these two women can recreate the chemistry that Flair and Banks once had. Moreover, a heel Charlotte Flair can also get a babyface Becky Lynch over.
We may be headed in this direction based on the events on SmackDown Live. Let's keep our fingers crossed and hope for the best.
