Overview
Hyun Gyu Lim is one of the most accomplished South Korean mixed martial artists of his generation and among the select group of Korean fighters to build a successful career inside the UFC.
Known by the nickname “The Ace,” Hyun Gyu Lim combined explosive striking with exceptional size for the welterweight division, earning a reputation as one of Korea’s most dangerous knockout artists during his competitive prime. Across a professional career spanning more than a decade, he competed in organizations including Spirit MC, HEAT, DEEP, Pacific Xtreme Combat (PXC), the UFC, and Double G FC before transitioning into coaching as the founder of Gym ACE MMA.
Before reaching the UFC, Hyun Gyu Lim established himself as one of Asia’s top welterweights by compiling an impressive undefeated streak and capturing the Pacific Xtreme Combat Welterweight Championship. His combination of athleticism, power, and finishing ability attracted the attention of the UFC, where he signed in 2012 and became one of the organization’s tallest welterweights.
During his UFC tenure, Hyun Gyu Lim earned victories over Marcelo Guimarães, Pascal Krauss, and Takenori Sato while sharing the Octagon with elite competitors including Tarec Saffiedine, Neil Magny, Mike Perry, and Daichi Abe. His memorable battles with Saffiedine and Krauss each earned Fight of the Night bonuses, cementing his reputation as one of Korea’s most entertaining fighters.
Early Life & Background
Born in Seoul, South Korea, Hyun Gyu Lim first developed an interest in combat sports through boxing before later training in Taekwondo during his teenage years. After completing his mandatory military service, he committed himself to mixed martial arts and was recruited by the coaching staff at Team Macho. Just a few months later, he made his professional debut in Spirit MC in 2006, beginning a journey that would eventually lead him to the world’s largest MMA promotion.
Hyun Gyu Lim steadily developed through Japan and Korea’s regional circuits, competing in organizations such as HEAT, DEEP, M-1 Global, and Pacific Xtreme Combat. His willingness to compete internationally helped accelerate his development while exposing him to a wide variety of fighting styles.
By 2012, Lim had emerged as one of Asia’s premier welterweight prospects after capturing the PXC Welterweight Championship, earning the UFC contract that many believed he had long deserved.
Fighting Style

Standing 6-foot-3 with a 77-inch reach, Hyun Gyu Lim possessed rare physical advantages for the welterweight division. He built his career around aggressive striking, long-range kickboxing, and devastating knees from the clinch, often overwhelming opponents with his size and offensive pressure.
A background in boxing and Taekwondo gave Lim an unconventional striking arsenal. He was particularly effective at using straight punches and knees against opponents attempting to close distance, while his willingness to engage created numerous memorable exchanges throughout his UFC career.
Although best known for his striking, Lim also developed competent defensive grappling and solid takedown defense, allowing him to keep many contests standing where his physical advantages could be fully utilized. Ten of his fourteen professional victories came by knockout or technical knockout, highlighting his reputation as one of Korea’s most dangerous finishers.
Professional Career

Hyun Gyu Lim made his professional debut in 2006 and quickly established himself as one of South Korea’s most promising welterweight prospects. After competing throughout Korea and Japan, he captured the Pacific Xtreme Combat Welterweight Championship in 2012, earning a UFC contract later that year.
Although his original UFC debut was postponed due to medical issues, Lim officially entered the Octagon in 2013 with an impressive second-round knockout victory over Marcelo Guimarães. He followed that performance with another spectacular first-round knockout over Pascal Krauss at UFC 164, earning his first Fight of the Night bonus.
In early 2014, Hyun Gyu Lim accepted a short-notice main event against former Strikeforce champion Tarec Saffiedine. Despite losing a hard-fought unanimous decision, the bout earned another Fight of the Night award and showcased Lim’s toughness against one of the division’s elite technicians. Later that year, he rebounded with a dominant first-round TKO victory over Takenori Sato in Japan.
The later stages of his UFC career featured bouts against Neil Magny, Mike Perry, and Daichi Abe before he concluded his Octagon run in 2017. Lim returned home for Double G FC, defeating former M-1 Global champion Igor Svirid by unanimous decision in the co-main event of the promotion’s inaugural event, closing his professional career on a victory.
