Ronda Rousey

"Rowdy" Ronda Rousey is not just an MMA fighter of supreme talent, she is also one of the most popular sportspeople on the planet. Such is the immeasurable popularity of the former UFC women's bantamweight champion that Rousey's appeal goes well beyond the octagon of which she has so regularly made her own. With a record of 12 victories and two defeats, the Californian remains one of the most influential figures the UFC has ever known.
