Meet Jessie Graff, the Supergirl stuntwoman and American Ninja Warrior competitor who made history (again) on the show, where advanced athletes compete in near-impossible obstacle courses.  In season five she was the first woman to qualify for the city finals. In this season, she&#x27;s the first woman to conquer the new 14.5 foot Warped Wall (aka SUPER HARD) in the Los Angeles qualifiers.  And she did it all while wearing a Wonder Woman costume.
