#2 Rey Mysterio may never turn heel
Another WWE Superstar whose character may never undergo serious alterations is Rey Mysterio. The former United States Champion is definitely one of the most talented in-ring performers of all time.
Everything from his look to his in-ring style speaks of an underdog. Widely recognized for his athleticism between the ropes, Vince definitely likes testing his monstrous heels against Mysterio.
He is arguably one of the few rare talents in the industry, who will always be loved and adulated as a babyface, and that only speaks volumes about Mysterio as a professional wrestler.
#3 Bobby Lashley may never turn face
I think we can all agree that Bobby Lashley deserves to be pushed as a legitimate threat on the main roster.
After returning to WWE as a face, the creative team failed to do enough to keep the fans invested in his character, with the gimmick eventually falling flat.
Moreover, his alliance with Lio Rush was an average affair. However, with Paul Heyman now working as the Executive Director of Monday Night Raw, we can only expect the All-Mighty to reach his full potential and receive an opportunity to collide against Brock Lesnar.
If the criticism his babyface run received is anything to take into account, it's hard to see Vince McMahon ever turning the former ECW Champion into a good guy.
