Passage: Chyna first rose to prominence in the World Wrestling Federation (WWF, now WWE) in 1997, where she was billed as the "Ninth Wonder of the World" (André the Giant was already billed as the eighth). A founding member of the stable D-Generation X as the promotion's first female enforcer, she held the WWF Intercontinental Championship (the only female performer to do so) twice and the WWF Women's Championship once. She was also the first woman to participate in the Royal Rumble match and King of the Ring tournament, as well as to become number one contender to the WWF Championship. With singles victories over several prominent male wrestlers – including multiple-time world champions Triple H, Kurt Angle, Chris Jericho, and Jeff Jarrett – Chyna left what WWE called "a lasting legacy as the most dominant female competitor of all time". After leaving the WWF in 2001, Chyna wrestled sporadically, with New Japan Pro Wrestling (NJPW) in 2002 and Total Nonstop Action Wrestling (TNA) in 2011. The latter was her final appearance in a wrestling ring.

Question: What was Chyna's persona in the WWF?
