#2 Face Turn - Alexa Bliss

Because she's so damn good at it, Alexa Bliss has been a heel for almost all of her time in both NXT and on the main roster. She originally debuted as a happy-go-lucky pixie fairy type who blew "pixie dust" when she was in the ring.
But since she honed her promo skills, she's been a heel for most of her run and one of the best heels in the ladies' division. WWE has loosely teased a face turn with her being nice to Nikki Cross, but everyone believes her kindness is only to serve her own interests. If Cross ends up turning on her, there you go, you have a face Alexa Bliss.
She's smaller so it would be easier for her to come across as a face. When the smaller stars are picked on by the larger ones, it's an easy heel-face dynamic. Bliss is talented enough to pull off either side of the coin, so if they feel she might have some untapped potential as a gallant babyface, Bliss is certainly a face turn that could be explored.
