#4. Former WWE Women's Champion Sable
Sable is widely considered one of WWE's first-ever divas and paved the way for the women in the company. Sable was part of two short stints with WWE that came to an end in 2004.
It was noted at the time that Sable left the company to spend time with her family. She is married to fellow WWE Superstar Brock Lesnar and welcomed two sons.

Sable was seen at ringside in UFC while supporting Brock. He has returned to WWE multiple times and has been a part of some of the biggest storylines but Sable opted to stay out of the promotion.
Sable hasn't wrestled for more than 15 years, and at 54 years old, it's clear that the former star has no interest in returning to the WWE.
