#1 Chyna
Chyna was a founding member of D-Generation X and held the Women's Championship once. She is also remembered as the only woman to have won the Intercontinental Championship. Furthermore, she boasted singles victories over several male wrestlers including multiple-time world champions Triple H, Kurt Angle, Chris Jericho, and Jeff Jarrett.
Chyna was the first woman to ever participate in the Royal Rumble in 1999. She also participated in the 2000 Royal Rumble making her a two-time participant, a feat that has never been accomplished by any other woman wrestler.

Her final match in WWE was at Judgement Day in 2001 where she successfully defended her Women's Championship against Lita. She left the WWF on November 30, 2001.
Chyna died on April 20 of an overdose of alcohol, combined with other drugs. Despite living a reckless life after WWE departure, her legacy cannot be duplicated. She was a once in a lifetime competitor who was a big contributor to the wrestling business. A posthumous induction into the WWE Hall of Fame is inevitable and well deserved.
