Seung Chul Lee (“Flash”) is a South Korean professional mixed martial artist competing for ONE Championship and representing DK Gym.

Since making his professional debut, Seung Chul Lee has quickly established himself as one of Korea’s most promising lighter-weight fighters, combining aggressive striking with well-rounded grappling to compile an impressive winning streak. His success on the ONE Friday Fights platform earned him a contract with ONE Championship, making him one of the newest Korean athletes signed to Asia’s largest martial arts organization.

Seung Chul Lee began his martial arts journey in South Korea, developing his skills through the country’s growing regional MMA scene before joining DK Gym in Uijeongbu. Training in a gym known for producing professional competitors, he quickly developed into one of Korea’s top flyweight prospects.

His rapid progression through domestic competition led to opportunities in Japan and eventually ONE Friday Fights, where his performances on the international stage brought him widespread recognition.

Nicknamed “Flash,” Seung Chul Lee fights with speed, precision, and relentless pressure. His compact frame allows him to close distance quickly, while his technical boxing creates opportunities to overwhelm opponents with combinations.

Although known primarily for his striking, Lee has proven to be a complete mixed martial artist. His professional victories include knockouts, submissions, and decisions, demonstrating an ability to adapt his game plan depending on the opponent. Tapology credits him with seven knockout victories, three submission wins, and multiple decision victories, highlighting his versatility inside the cage.

Seung Chul Lee turned professional in 2022 and immediately established himself as one of Korea’s fastest-rising prospects. After building momentum on the regional circuit, he earned an opportunity to compete on ONE Friday Fights, where he impressed against increasingly experienced international opponents.

Victories over fighters such as Moises Ilogon, Van Nam Pham, Koha Minowa, Cueng Naibaho, and Fábio Henrique helped extend his winning streak and ultimately secured him a full ONE Championship contract. His unanimous decision victory over the previously highly regarded Fábio Henrique at ONE Fight Night 41 further solidified his reputation as one of the organization’s emerging strawweight contenders.

Outside of competition, Lee also serves as one of the lead coaches at DK Gym, sharing his experience with both amateur and professional athletes while continuing to compete at the highest level.
