#3 Samoa Joe
He is the former two-time NXT champion and is known throughout the world as the Samoan Submission machine. For good reason, too, as he's been known to stretch his fair share of opponents.
Joe first earned a name for himself competing for Ring of Honor, having captivating matches against the likes of Bryan Danielson, CM Punk and Nigel McGuiness.
After departing ROH, he competed for TNA, and it was while he was there that he had matches against the likes of Kurt Angle, Sting and AJ Styles. It seemed as though Joe had achieved all that he needed to achieve. That was, everything other than competing for WWE.
In 2015, Joe arrived at the end of an NXT Takeover event, coming face-to-face with the then-champion Kevin Owens. The encounter was epic, even though all that took place was a stare down between the two and nothing more.
What fans may be unaware of is the fact that this wasn't the first time he had worked for WWE. Before Joe made a name for himself, a younger, more slender and blond Joe fought on Sunday Night Heat, one of their secondary TV programs.
At the time, neither Joe nor the WWE could have predicted that years later he would be booked to become the focus of one of their brands.
