#2 AJ Styles vs Charlotte Flair
AJ Styles and Charlotte Flair have had similar experiences in WWE, with both taking a little while to completely settle on the main roster. But once they did, success and championships followed throughout. The similarities do not end there. Both of them are of similar stature and they possess the athletic ability, as well as the aptitude for technical and brutal mastery in the ring.
The flurry of moves these two could bust out against each other would be amazing to watch. Moonsaults, DDTs, chops, kicks and more, AJ Styles and Charlotte Flair could feasibly put on a classic. There even is an in-built story, with Styles being Ric Flair's protege in TNA. It also helps that he and Charlotte are really good friends, as evidenced by social media. This is one match that would be a no-brainer if WWE does sanction inter-gender wrestling in the future.
