#4 Gail Kim

Gail Kim doesn't get nearly the amount of credit she deserves. The GFW Hall of Famer did some tremendous work with the WWE, before moving on to the company formerly known as TNA. There she championed the company's Knockouts division long before the women's revolution began in WWE.
When Gail wrestled in WWE she probably never envisioned plying her trade elsewhere. Vince McMahon's company is the top table in wrestling after all. Well, she did of course, so it's extremely fortuitous that she was allowed to use her own name.
Top name doesn't want to enter the WWE Hall of Fame. More details HERE.
When Gail Kim arrived in TNA she already had a lot of name recognition in the business. She hadn't wrestled under a name created and owned by WWE, therefore, she didn't have to change a thing when she moved on. Smart business on Gail's part, and one of the many reasons why she went on to enjoy so much success after WWE.
