#4 Charlotte Flair and Andrade
Charlotte Flair is arguably one of the greatest female WWE Superstars in the history of the company. In a relatively short career on the main roster, she already is a multi-time Women's Champion, having won the RAW Women's Championship four times, the SmackDown Women's Championship five times, and the NXT Women's Championship twice.
Her relationship with fellow WWE Superstar Andrade is a well-known one as the two constantly keep their fans updated about their lives through their social media platforms.
While both perform together on the same brand of Monday Night RAW (Charlotte has recently moved to NXT after becoming the NXT Women's Champion but still appears on RAW), we are yet to see the two team-up or work together in a storyline.
Andrade, the current United States Champion is managed by Zelina Vega, and that pairing has proved to be amazing for both of them. El Idolo has all the potential to be one of WWE's top Superstars in the future.
Charlotte's on-screen gimmick of The Queen might not necessarily suit that of Andrade, a potential reason why the company hasn't paired them together yet. But there's a lot of time to go in both of their careers and one can't deny the possibility of an alliance.
Maybe we can see them as a team if WWE decides to bring back the Mixed-match challenge.
