#4 Alundra Blayze
Madusa, who worked in WWE under the ring name Alundra Blayze, was a three time WWE Women's Champion, and was the first ever female wrestler to have won the WCW Cruiserweight Championship.
Blayze is considered to be one of the pioneers of the women's division in WWE, and when she was brought in by Vince McMahon, she remained the focal point around which the rest of the division was built. In December 1995, when Blayze was in the midst of her third and final run as the WWE Women's Champion, Vince McMahon decided to let her go owing to financial troubles the company was in at the time.
Blayze never formally dropped the title, and instead showed up on WCW Monday Nitro with the championship. In one of the most controversial angles at the time, Madusa threw the WWE Women's Championship in a trash can on live television, and the title was left vacant for the next three years.
This also resulted in WWE blacklisting Blayze for nearly two decades – until she was inducted into the WWE Hall of Fame in 2015!
