#2 Charlotte Flair

Charlotte Flair is another worthy opponent for Ronda Rousey at WrestleMania 35. She performs on SmackDown Live, but a brand switch is possible before WrestleMania. However, Charlotte could also win the women's Royal Rumble next year and challenge Ronda Rousey. She is set to compete in a triple threat match at TLC.
Charlotte's achievements are incredible in WWE, and she is already one of the best female superstars to compete in the squared circle. She made her main roster debut in 2015, but she has already won a total of 7 titles on the main roster.

As a matter of fact, she also won the NXT women's title on the yellow brand. Charlotte and Ronda faced each other at Survivor Series, and it was a spectacular match. Ronda won the match via disqualification, but Charlotte dominated the match.
Charlotte ended Asuka's undefeated streak at WrestleMania 34, and she could be the superstar to stop Ronda's winning streak. Therefore, Charlotte might get an opportunity to break another winning streak at WrestleMania 35.
