2. Bayley
Bayley is also set to return to WWE soon and has been one of the most prominent stars in the company over the past several years. With the two having an established history, it would be easy to restart this feud.
Since both are considered main event-level performers, there's no question that the matches and the build have the potential to be great. One potential pitfall lies in the booking of the finishes, since both will have to be positioned to look strong regardless of the outcome.
1. Bianca Belair
This would probably be the most intriguing match for the returning star. Asuka has not met Bianca Belair one-on-one as part of the main roster, and it is clear that the company still considers Belair a top-level talent.
As Belair is still working to rebuild herself after losing the SmackDown Women's title to Becky Lynch, a feud of this caliber would put her back into the main event scene. However, similar to a match between Asuka and Bayley, the outcome would need to be booked in a way where both performers come away looking strong.
