#3 Asuka

One of the other fiercest women on the roster is Asuka. She was built up as the most dominant woman in NXT history with an undefeated streak. That streak was maintained until she fell to Charlotte Flair at WrestleMania 34.
Throughout her entire run in both NXT and her early run on the main roster, the Empress of Tomorrow was booked as one of the most feared and dangerous women. She is still just that and is arguably the best female performer in all of WWE. Rousey and Asuka never had a one on one match. At the time, the Empress of Tomorrow was a part of SmackDown while Rousey was on RAW.

It makes a lot of sense to have these two face each other due to the air of legitimacy each woman possesses. They're also extremely gifted submission artists which often makes for captivating wrestling. Asuka has mainly been a featured part of the Women's Tag team division since last WrestleMania. Along with Kairi Sane, she's held the titles since Hell in a Cell in October of 2019.
The Empress of Tomorrow and Kairi Sane should both return to singles competition once they lose the titles. The booking of the belts has been inconsistent but does give some exposure to a more diverse collection of the roster. Depending on how things play out with a potential Superstar Shake Up following the Show of Shows, a showdown between Rousey and Asuka needs to happen.
