#2. Bayley

Bayley had a career resurgence when moving to SmackDown in 2019. She debuted on RAW a month after the Draft and had close to instant success, defending the RAW Women's Championship successfully at WrestleMania 33. Despite her fall after that, she managed to rack up a decent set of accomplishments, but 2017 and 2018 are years she'll likely prefer to forget about.
Since moving to SmackDown in the 2019 Superstar Shake-Up, she was given another push and slowly built up to a Money in the Bank victory. She would cash in on the same night and become SmackDown Women's Champion, a title that she briefly lost before regaining.
She will be walking into her third WrestleMania as a titleholder, having won the Women's Tag Team title last year as well. Given the success that she's had on SmackDown along with a heel turn and alliance with Sasha Banks, it's clear that the blue brand is a better place for her to be. She's dominated since coming and we can see her being a central figure for a while to come.
