25. Ronda Rousey
The woman who started it all, Rousey is absolutely deserving of recognition despite the way in which she ended her career. Rousey hasn’t fought since 2016, and lost each of her last two fights in brutal fashion. However, in just five years as a professional mixed-martial artist, Rousey did more for the sport than any other woman in history. Fans tuned in to watch Rousey devour opponents, and she most often delivered. She won her first twelve pro matches by either submission or knockout — eight within the first minute of the fight and only one went beyond the first round. She’s an icon within the sport, and will be remembered for a long time to come.
