In the main event of ONE: Big Bang II, former ONE Flyweight Muay Thai World Champion and current #3-ranked contender Jonathan “The General” Haggerty  of the United Kingdom dominated Japan’s Taiki “Silent Sniper” Naito  across three action-packed rounds.
Haggerty showcased his trademark ring IQ, calculating distance and deciphering Naito’s rhythm before putting on a striking clinic. “The General” had his complete arsenal on display, including a plethora of feints, thudding leg kicks, and sharp boxing combinations.
A bullet-like right hand down the middle in round one dropped Naito for the count, but the Japanese athlete was able to regain his footing. In the second frame, Haggerty again connected with a haymaker, this time a wild right hook that sent Naito down to the canvas once more. Naito tried his best to turn his luck around in the third stanza, but Haggerty cruised to the final bell. In the end, all three judges scored the bout in favor of Haggerty, who earned the convincing unanimous decision victory.
In a ONE Super Series kickboxing contest, #1-ranked contender Nieky “The Natural” Holzken  of the Netherlands got back in the winner’s column with a crushing body shot knockout of #5-ranked contender Elliot “The Dragon” Compton  of Australia. Holzken weathered an early storm from Compton and then landed the debilitating liver shot, which sent “The Dragon” to the canvas. Compton could not beat the count, and Holzken was awarded the KO victory.
South Korea’s “The Fighting God” Kim Jae Woong  turned in one of the finest performances of his career with an exciting TKO victory over #4-ranked mixed martial arts featherweight contender Tetsuya “MMA Fantasista” Yamada  of Japan. The bout began with Kim on the offensive, as he pressed Yamada against the Circle Wall with thunderous combinations. Yamada tried to take matters to the ground but found no success. In the second round, Kim maintained his aggressiveness, blasting Yamada with a frightening display of ground-and-pound. Yamada offered little resistance, and the referee called a halt to the contest.
In a showdown between hard-hitting heavyweight kickboxers, 23-year-old Rade Opacic  of Serbia authored a stunning knockout finish of Muay Thai and Kickboxing Champion Errol “The Bonecrusher” Zimmerman  of the Netherlands. In round one, Opacic and Zimmerman traded their best shots at the center of the Circle, testing each other’s chins on multiple occasions. In the second round, Opacic unleashed a picture-perfect spinning heel kick that landed right on the jaw, sending Zimmerman down and forcing the referee to call off the fight.
Former ONE Welterweight World Title challenger Tyler McGuire  of the United States overcame a spirited effort from Malaysian star Agilan “Alligator” Thani  to earn a unanimous decision victory in their mixed martial arts contest. It was a high-level wrestling battle through two rounds, as the two athletes showcased their ground skills, traded dominant positions, and attacked from various angles. McGuire, however, controlled more of the fight and put in a dominant third round to pull away on the judges’ scorecards.
Chinese mixed martial artist “The Ghost” Chen Rui  kicked off the action at ONE: BIG BANG II with an explosive first-round stoppage of Iran’s Ali “Moti” Motamed . Chen walked through a plethora of kicks from “Moti” to land his boxing combinations. A left hook dropped Motamed, and Chen followed up with punches to earn the finish.
