I remember reading a story about a man pretending to be a woman and fighting women in mixed martial arts competitions. What was the name of that man?

The man was named Fallon Fox. She was a transgender female mixed martial arts (MMA) fighter who competed between 2006 and 2016. Fox competed as a man before transitioning to be a woman in 2013. She gained notability for becoming one of the first openly transgender athletes to compete in professional MMA. Fox's story was featured in ESPN's 30 for 30 documentary series, as well as a 2019 documetnary named Ghosts in the Machine.
