6. Mark Henry
Remember when Mark Henry was that boring guy who nobody wanted to see? Even 2 years ago his return would be greeted with groans and complaints that WWE wasted a spot by filling it with the supposed World's Strongest Man. In 2013 however, a Mark Henry return is something else - he's a star, he's an attraction, he's Mark Henry version 10.0. Henry was a dominant World Champion who only lost his belt because of injury and had originally been scheduled to hang onto the strap right up to Wrestlemania. It's about time he made his comeback, and slightly tweaking his character to give him face qualities would be enough to put him on a collision course with Big Show at Wrestlemania. Failing that he could return as a heel and dominate, perhaps setting up a feud with Ryback that will help get Ryback away from his ill-fated feud with WWE Champion CM Punk. This all depends on whether Henry ever returns from his injury though. And as Mark has said himself, that remains to be seen.
5. Jack Swagger
Apparently Jack Swagger has been promised a new persona when he returns to the main roster in 2013. He needs it. His comedic, Kurt Angle style role when he was champion was all good and well but with the obvious upsides he has there's no reason why he couldn't be a huge babyface going forward. Jack Swagger has been off WWE TV for long enough now to completely reinvent himself. He could be the modern era American Hero, waging war on the likes of Antonio Cesaro before entering into a lengthy feud with his old running buddy Dolph Ziggler - what a match that would be! Recent house show results indicate however that Swagger is still the same guy, losing quickly to people like Santino. Hopefully they're saving this new look Swagger for TV. Fingers crossed.
