In late 2015, Ronda Rousey was the UFC.
She'd become the face of the franchise, the most recognizable female athlete in the U.S. and had made her way to acting crossovers in motion pictures and at WrestleMania.
She was 12-0 as an MMA pro and 6-0 in the Octagon, winning each match inside the distance and only once venturing beyond the first round.
Her last four bouts, in fact, had lasted a grand total of 130 seconds. Combined.
So Holly Holm, in spite of a distinguished, championship-level boxing career, was not considered a significant threat to upend bantamweight dominance in her third UFC fight.
But soon after the main event at UFC 193 began, perception changed.
Holm eluded Rousey's early attempts to get to the mat and consistently held her own when it came to striking, eventually tiring the champion as the initial round wound down.
The gas tank was all but empty as Round 2 began and the challenger took advantage, ultimately landing a high kick to the right side of Rousey's head that left her defenseless.
The fight was waved off at 59 seconds of the round and the Rousey era was over.
She fought only once more, losing in 48 seconds to Amanda Nunes, before eschewing the sport for a full-time run with WWE.
Holm, meanwhile, dropped the belt to Miesha Tate in her first defense four months later and is just 4-5 in nine bouts since, including a split-decision loss to Ketlen Vieira in May.
