Fallon "The Queen of Swords" Fox on the Jones - Holland Scale:
As a teenager, Fox believed she may have been a gay man, but learned the term "transgender" at the age of 17. Fox continued living as a heterosexual man and married her then-girlfriend at the age of 19, when the latter became pregnant with their daughter.
Fox joined the US Navy to support her new family and served as an operations specialist on the USS Enterprise.
Fox enrolled at the University of Toledo, but dropped out after ongoing psychological stress from her unresolved gender issues.
Fox worked as a truck driver in order to afford sex reassignment surgery.
Fox and her daughter moved to Chicago, Illinois, and in 2006, Fox traveled to Bangkok, Thailand, to undergo feminizing gender reassignment surgery, breast augmentation, and hair transplant surgeries at a hospital in Bangkok.
Fallon Fox came out as transgender on March 5, 2013, during an interview with Outsports writer Cyd Zeigler and Sports Illustrated, following her two initial professional fights in the women's division. Fox claimed in her video interview with Cyd Zeigler to be within the rules of organizations such as the International Olympic Committee (IOC) for postoperative transsexuals and wishes to continue fighting in MMA.
During Fox's fight against Tamikka Brents on September 13, 2014, Brents suffered a concussion, an orbital bone fracture, and seven staples to the head in the 1st round. After her loss, Brents took to social media to convey her thoughts on the experience of fighting Fox: "I've fought a lot of women and have never felt the strength that I felt in a fight as I did that night. I can't answer whether it's because she was born a man or not because I'm not a doctor. I can only say, I've never felt so overpowered ever in my life and I am an abnormally strong female in my own right", she stated. "Her grip was different, I could usually move around in the clinch against other females but couldn't move at all in Fox's clinch."
In 2014, Fox was inducted into the National Gay and Lesbian Sports Hall of Fame.
A tweet from Fox in 2020 said: "For the record, I knocked two out. One woman's skull was fractured, the other not. And just so you know, I enjoyed it. See, I love smacking up TEFS [sic] in the cage who talk transphobic nonsense. It’s bliss!"
Fox was raised Christian, but has since become an atheist.
