About Demetrious Johnson

Thirteen-time Flyweight World Champion Demetrious “Mighty Mouse” Johnson is widely considered one of the greatest pound-for-pound mixed martial artists of all time. In 2018, after completely dominating the highly competitive North American scene with a record-setting run of 11 World Title defenses, Johnson decided to make ONE Championship his new home as part of a landmark deal.

Johnson’s meteoric rise to greatness was borne of sheer determination and hard work. He grew up in incredibly adverse circumstances, being raised by his hearing-impaired mother and an abusive stepfather. However, he never let his circumstances get the better of him. Johnson became a successful athlete in high school, competing in several sports on the way to a second-place finish at the Washington State Wrestling Championships.

This success on the mats led him to try his hand at mixed martial arts in 2007, and it resulted in one of the most incredible careers ever seen in the sport. Though he enjoyed great returns at bantamweight, a move to flyweight in 2012 saw Johnson really come into his own. He tore through several tough contenders on the way to capturing the UFC Flyweight World Championship, defending it an amazing 11 times to etch his name into history.

“Mighty Mouse” etched his name once more by defeating three of the top flyweights in Asia — including Yuya Wakamatsu, Tatsumitsu Wada, and Danny Kingad — to claim the ONE Flyweight World Grand Prix Championship in October 2019.

Along with the prestigious silver Grand Prix belt, Johnson was awarded a shot at longtime ONE Flyweight World Champion Adriano Moraes. The bout happened at ONE on TNT I in April 2021, but to the shock of fans around the globe, the American was finished for the first time in his 15-year professional MMA career, as the defending titleholder knocked him out with a knee.

That setback, however, set up the ultimate comeback. In March 2022, Johnson defeated Thai megastar Rodtang Jitmuangnon in a historic special rules super-fight, and five months later, he earned his redemption against Moraes. At ONE on Prime Video 1, he became the first person to finish the Brazilian – coincidentally, with a knee – to capture the ONE Flyweight World Title, become an unprecedented 13-time MMA World Champion, and cement his status as the GOAT.
