#7 Bayley
The longest-reigning SmackDown Women's Champion in WWE history, Bayley made her NXT TV debut in March 2013 and just like Sasha Banks, lost to Paige.
Bayley had to bide quite some time before she would eventually win the NXT Women's Championship against Sasha Banks at NXT TakeOver: Brooklyn in 2015. She would then defend her title against the likes of Carmella, Alexa Bliss, Nia Jax, and Eva Marie but would eventually drop it to Asuka.
The Hugger's first world title would come in the form of the RAW Women's Championship which she won after beating Charlotte on the February 13 episode of the Red brand with the help of her best friend Sasha Banks. She also won the WWE Women's Tag Team Championship with Banks at Elimination Chamber last year.
Currently, Bayley is the only woman Grand Slam Champion in the company, having won every women's title across WWE's three brands. She will defend her SmackDown Women's Championship next against Tamina at Money in the Bank next month.
