3. Marty Scrull
From humble beginnings as Party Marty to The Villian, Marty Scrull is without question one of the hottest prospects on the independent circuit at the moment and thanks to his association with NJPW's Bullet Club, his cache continues to rise.
Marty is a complete package having honed his craft in wrestling rings across all the globe. Not only is he no slouch in the ring but his promos and character are almost tailor-made to be successful in WWE; he could easily be dropped onto one of the main rosters today and make an immediate impact.
Marty also has the ability to have a great match with seemingly any opponent and can wrestle serious technical matches whilst injecting his British wit and comedy when needed without losing face.
You'd have to be blind to not see the dollar signs when it comes to Marty Scrull and you have got to believe that his fellow countryman, William Regal (who has been influential in talent scouting for WWE over the last several years), has had Marty's name on his top prospects list for the last several years.
At only 29, Marty can pick and choose when he makes his journey to Stamford and seems very happy with his current roles in NJPW and ROH. However, I would bet the house that eventually we will see The Villian grace the rings of the WWE.
Woo, Woo.
