#4 Xavier Woods

Okay, so Xavier Woods didn't technically leave TNA for WWE, but his inclusion on this list is down to the fact that he is a rare example of a released TNA star going on to become a megastar in the WWE.
Xavier Woods wrestled under the name 'Consequences Creed' during his time in TNA, but was released from the company in 2010.
After a very brief spell in NJPW, Woods signed a developmental deal with the WWE, and the rest, as they say, is history.
Woods made his main roster debut in 2013 as part of a team with R-Truth. Just over a year later, Woods would change his gimmick and become a member of The New Day alongside Big E and Kofi Kingston. Despite some growing pains, the group would go on to become one of the most successful tag-teams of the modern era and are the current SmackDown tag-team champions.
