Let Fallon Fox fight
Fallon Fox is 5-foot-7, 144 pounds and totally, utterly ripped. She is a mixed martial artist who goes by "The Queen of Swords" while in the ring. She kicks asses, often quite literally, for a living. In her most recent MMA match, she KO'd Erika "Pitbull" Newsome in 0.39 seconds flat with a knee to the face. After a quick succession of wins, she has her sights set on entering the women's Ultimate Fighting Championship.
She also happens to be transgender.
