#4 Dean Ambrose
Last year the Lunatic Fringe got injured and was sidelined for almost nine months.
A few years ago he was the WWE Champion, and his title reign was also looking quite good. He won the Intercontinental Championship on many occasions and also managed to become Raw Tag Team Champions along with Seth Rollins.
He returned on Monday Night Raw before this year's Summerslam where Rollins revealed that he would be standing at ringside during his match.
Many fans expected that now his career will become better as the rumours were indicating a heel turn from his side.
From the past few weeks, the company is also teasing his heel turn, but so far, things are looking same as before. Now everyone is expecting that in a few weeks from now, he will officially turn against his Shield brothers.
A heel turn could change many things for him because it is something we have not seen in a very long time.
