#4. Bray Wyatt
Bray Wyatt hasn't wrestled on WWE TV since August when he lost his Raw Tag Team Championships to The B Team and Matt Hardy was then forced to walk away from the ring because of an on-going injury.
Wyatt was given time off following a car accident so that he could heal from his injuries, but he has been cleared to return for the past few months, even though the company has nothing creative for him right now. The Royal Rumble is the perfect place for any superstar to pick up a rivalry and could be Wyatt's only chance of picking up a rivalry ahead of WrestleMania.
Since Luke Harper, Erick Rowan and Bray Wyatt are all now cleared to return, it would be a shame if WWE didn't reunite The Wyatt Family if only for one night.
