#4 Ronda Rousey (WWE Free Agent)
Former WWE RAW Women's Champion Ronda Rousey hasn't been seen on WWE programming since WrestleMania 35, where she was pinned by Becky Lynch in the main event.
There has been lots of talk that Vince McMahon is eager for Ronda Rousey to return to WWE for a WrestleMania match with Becky Lynch. A great way to set this up would be to have the former UFC star return at the Royal Rumble in January.
Ronda Rousey is currently listed at 7/1 on the UK's SkyBet, and her name is often one that has cropped up during discussions of the event. If The Baddest Woman on the Planet does indeed return to take part in the 2021 Royal Rumble, it will be the first time she has competed in the event.
If Ronda Rousey ends up winning the match, it would be interesting to see who she would choose to challenge at WrestleMania in the springtime. Ronda Rousey has already proven that she is able to carry a huge WrestleMania feud, so it may not be long until fans see her next one.
