#2. Former WWE Women's Champion Gail Kim
Gail Kim is mostly associated with IMPACT Wrestling but started her wrestling career in WWE. Kim won the Women's Championship as part of her first televised match on RAW in 2003.
Kim was later sidelined with a broken collarbone before returning to action in the spring of 2004. The former champion was surprisingly released from her contract in the fall due to budget cuts.
Kim revealed that she was initially caught off-guard but noted WWE released her as they wanted to take the division in a new direction.
She later returned to WWE for a short stint from 2008 until 2011. Kim walked out of the company during a battle royal on RAW.
Kim has since become a record 7-time Knockout's Champion on IMPACT Wrestling and a part of the IMPACT Wrestling Hall of Fame. The star has made it clear that she has no desire to return to WWE but is working behind the scenes for IMPACT.
