#2 Alexa Bliss
In less than four years on the main roster, Alexa Bliss has accomplished almost everything. She is a multi-time RAW Women's Champion, a former Smackdown Women's Champion as well as a two-time, and current Women's Tag Team Champion. Bliss has also won and successfully cashed in a Money in the Bank contract. To say that WWE sees value in her would be an understatement.
In-ring credentials aside, Alexa Bliss is incredibly charismatic with a strong grip on the microphone. Even when she wasn't cleared to compete back in late 2018 - early 2019, WWE kept utilizing her in a non-wrestling capacity. She was given her own talk-show (A Moment of Bliss) and was declared the host of Wrestlemania 35.
While it's unknown how much longer Bliss plans to wrestle, she can always transform into a manager once she wraps things up. A female mouthpiece is quite rare in modern Professional Wrestling and maybe Alexa Bliss can change that.
For now, however, "Little Miss Bliss" has a lot of stories to tell inside the squared circle.
