#4 Asya - Chyna
Joan 'Chyna' Laurer was a true pioneer in the WWF, as the first woman to win a predominantly men's championship, as well as the first woman to enter the men's Royal Rumble.
A huge draw in the company at the time, WCW were quick to capitalize on the Ninth Wonder of the World, with Asya, a bodybuilder turned wrestler, much like Chyna herself.
Unfortunately for the Georgia-based promotion, Asya lacked Chyna's charisma and athleticism, and WWE struggled to find meaningful feuds for her, a stark contrast to Chyna's battles as part of D-Generation X and later with Chris Jericho.
A pet project quickly forgotten about by WCW, Asya never amounted to much in wrestling, whilst Chyna will soon be taking her rightful spot (albeit posthumously) in the WWE Hall of Fame.
