#1 Holly Holm vs. Ronda Rousey
At one point in time, Ronda Rousey was the most-talked-about celebrity in the world of sports and entertainment. That was back in 2015, when Rousey had seemingly run through most of her competition, and was scheduled to defend her UFC Women's Bantamweight Title against a former professional boxer-turned-MMA fighter Holly Holm.
Rousey was everywhere -- on news channels, at movie premieres, magazine covers, mainstream talk shows, et cetera. Eventually, UFC 193 beckoned, and the Octagon door closed with Rousey and Holm ready to exchange leather for the title.

Well, who could've possibly imagined at the time that UFC 193 will go down in MMA history as a night of the biggest upset in WMMA! Holm defended well against Rousey in the clinch, and even managed to secure a takedown on "The Rowdy One".
Moreover, after having boxed up Rousey in Round 1, Holm continued doing so in Round 2 -- before hitting Rousey with one of the most brutal head-kicks of all time. Holm followed up with a few ground strikes, and that was all she wrote!
Rousey was beaten by way of KO, and Holm was the new UFC Women's Bantamweight Champion. An iconic moment, which had come to fruition with great game-planning and a memorable KO.
