#2 Former WWE Women's Champion Ronda Rousey
The WWE return of former RAW Women's Champion Ronda Rousey has been hotly rumored for quite some time now. The star has been spotted training with James Storm, and also in WWE's Performance Center.
Ronda Rousey hasn't wrestled a match in WWE in 2020 and was last seen in the ring at WrestleMania 35. There, she was pinned by Becky Lynch, who became the RAW and SmackDown Women's Champion in the main event.
Ronda Rousey's training, along with reports that Vince McMahon is eager for her to work WrestleMania 37, there is a strong possibility that The Baddest Woman on the Planet will be returning to WWE sooner rather than later.
Ronda Rousey coming back to WWE at the 2021 Royal Rumble would be a great moment for fans of the former UFC star. A surprise Royal Rumble appearance is a great way to bring WWE Superstars back into the mix, especially fan favorites such as Rousey.
As well as this, Ronda Rousey made her first appearance as a full-time WWE Superstar at the end of the 2018 Royal Rumble to confront Alexa Bliss and Charlotte Flair.
So, a 2021 Royal Rumble return would feel very much like a full-circle moment for the star.
