ONE double champion Christian Lee is one of the fiercest and toughest titleholders the sport has ever seen.
Boasting an impressive 17-4 professional record, Lee has only been soundly defeated once, courtesy of former ONE featherweight and lightweight world champ Martin 'The Situ-Asian' Nguyen.
In 2016, Nguyen handed Lee his first defeat via a slick guillotine in the first round. Two years later, the two met each other again inside the circle, where Nguyen barely scraped a split decision win over 'The Warrior'.

To this day, 'The Situ-Asian' is the only fighter to have ever defeated the dominant ONE lightweight and welterwelt champion twice. Lee is still yet to avenge his defeats to Nguyen.
In their rematch, Christian Lee and Martin Nguyen put on an intense showdown that kept the audience on the edge of their seats. Each attack was returned with a counter while the two warriors expertly denied each other any chance to tip the scales.
In the end, it was Nguyen who got the judges' decision in a razor-close and hotly contested bout.

Christian Lee had one of the best years of his career in 2022
If not for ONE light heavyweight and interim heavyweight world champion Anatoly Malykhin winning the accolade, Christian Lee could have been ONE's Mixed Martial Arts Athlete of the Year.
'The Warrior' reclaimed the ONE lightweight belt by avenging his loss in 2021 and then became a two-division world champ just a few weeks later. Both wins came in absolutely devastating fashion.
In August last year, Lee avenged his loss to Ok Rae Yoon by utterly dominating their rematch and recapturing his belt. The two-round affair that took place at ONE 160 was one of the most frightening and one-sided beatdowns ever seen in the promotion.
Just three months after reclaiming the lightweight throne, Christian Lee moved up 15 pounds to challenge Kiamrian Abbasov for the ONE welterweight world title.
After weathering an early scare that saw him nearly get finished by the now-former world champ, Lee bounced back and pressed the action until he slowly sapped Abbasov's energy. By the fourth round, Abbasov pretty much had nothing left in the gas tank and Lee took the world title via TKO.
