Intergender singles bouts were first fought on a national level in the 1990s. This began with Luna Vachon, who faced men in ECW and WWF. Later, Chyna became the first female to hold a belt that was not exclusive to women when she won the Intercontinental Championship. While it is a rare feat in WWE, in TNA, ODB participates in singles intergender matches. Also, ODB's kayfabe husband and tag team partner Eric Young held the Knockouts Tag Team Championship for a record 478 days before it was stripped by Brooke Hogan because Young was a male.
