Michelle McCool

The Undertaker's wife was quite the star within WWE before her departure. She was a two-time Divas Champion and two-time Women's Champion during her career. Not only that, she formed a tough team known as LayCool thanks to her aligning with fellow superstar Layla. Fans wouldn't mind seeing both Michelle and Layla come back to the ring for another tag team match, probably. At 38, one would think McCool can still give it a go in the ring.
