Becky Lynch

Becky Lynch was the female draft pick of SmackDown in 2016 and the Irish Lasskicker went on to become the first ever Women's Champion of the brand a few weeks after the first episode of the show. Lynch defeated Natalya in a singles match to kick off her career on the blue brand.
Though Becky had lost her direction in 2017, she bounced back like a champion in 2018 and is currently the hottest thing in the entire company.

Alexa Bliss

Alexa Bliss was seen as a push-over from NXT who was promoted to Smackdown just to make up the numbers. She debuted on the blue brand by interrupting Becky Lynch during her post match promo, along with Naomi, Carmella and Eva Marie.
Bliss has won the Women's Championships of both RAW and SD Live multiple times and the Five Feet of Fury is currently away from the ring recovering from her injuries.
