5 most surprising heel turns that WWE can pull off before WrestleMania 37

#4. Rey Mysterio - Has never been a heel in WWE

Over the course of the last year in WWE, the most important thing Rey Mysterio has done was to introduce his son Dominik Mysterio to the world. Dominik Mysterio made his long-anticipated debut at SummerSlam 2020 against Seth Rollins and delivered beyond expectations.

It's understandable as to why WWE has never turned Rey Mysterio heel. Not only was he a top merchandise-seller in his prime years, but he was a key to the Latin American market.

To add to that, Rey Mysterio was always one of WWE's most beloved babyfaces. But all of that can change. A year ago, it was unimaginable that someone like Rey Mysterio could turn heel. But with Dominik Mysterio present, an interesting direction could happen.

While Dominik Mysterio could turn heel, he doesn't seem ready for a big character switch. Rey Mysterio making a heel turn would rank as one of the most shocking WWE moments of the last few years, and it would do wonders to elevate his son.
