Overview
Yeon Kyun Kim, better known by his nickname “God Gyun,” is a South Korean welterweight and middleweight representing Cube MMA.
Yeon Kyun Kim owns a 3–3 professional MMA record, with one submission victory and two wins by decision. He has yet to record a professional knockout or TKO, making him a fighter whose success has generally come through grappling, control and the ability to win rounds rather than overwhelming finishing power.
His career has primarily developed through GFC and Black Combat, with four of his six professional appearances taking place under the Black Combat banner.
Yeon Kyun Kim’s early career has also been defined by significant fluctuations in weight. His professional debut took place at a 172-pound catchweight, his second fight at 179 pounds, his first Black Combat appearance at openweight and his Black Combat 6 fight against Jun Seo Choi at middleweight.
More recently, however, Kim appears to have settled at welterweight, competing at 170 pounds in both his 2025 victory over Gilberto Macedo and his 2026 fight against Sander Silva.
That move could prove important for evaluating what level Kim can ultimately reach.
Early Life & Background
Very little verified information is publicly available regarding Yeon Kyun Kim’s childhood, date of birth, education or initial introduction to martial arts.
Tapology does not currently list his age or reach. He is listed at 5’10” (178 cm) and represents Cube MMA, a Korean team that has produced several fighters competing throughout the country’s regional MMA scene.
Yeon Kyun Kim’s professional career began relatively recently.
He made his professional debut on May 1, 2021, facing Do Hyung Kwon at GFC 05. The bout was contested at a 172-pound catchweight.
Kwon entered the matchup with considerably more professional experience, and Kim’s debut ended when he was caught in an armbar at 2:38 of the opening round.
Kim therefore began his professional career 0–1.
Rather than immediately returning at lightweight or welterweight, his subsequent fights took place across several weight categories as he developed his professional game.
By late 2022, Kim had joined Black Combat’s Champions League system, which would become the primary platform for the next stage of his career.
Fighting Style
Kim’s professional results point toward a grappling-oriented all-around style built more around control than finishing power.
He has never recorded a professional knockout.
His three victories consist of two decisions and one submission, while his lone submission victory came through a rear-naked choke.
The best demonstration of Kim’s grappling ability came against Hyun Woo Jeon in his Black Combat debut.
Kim needed only 1:03 of the opening round to take Jeon’s back and secure the rear-naked choke, producing the fastest victory of his professional career.
That performance showed that while Kim may not be a prolific finisher, he is capable of capitalizing quickly when an opponent gives him a dominant grappling position.
His decision victories provide another piece of the picture.
Yeon Kyun Kim defeated Sung Yoon Kim over two rounds in 2022 and later defeated Brazilian Gilberto Macedo over three rounds in 2025. The Macedo victory is particularly useful for evaluating his development because it demonstrated that Kim could maintain his game across a full 15-minute professional fight.
At the same time, Yeon Kyun Kim’s losses reveal areas where stronger opposition has been able to expose him.
He was submitted by Do Hyung Kwon in his professional debut, stopped by Jun Seo Choi with knees and punches in 2023 and outpointed by Sander Silva in 2026.
That means Yeon Kyun Kim has now experienced all three primary types of professional defeat: submission, knockout/TKO and decision.
His style is therefore better characterized by versatility and competitiveness than dominance in one particular phase.
Professional Career
Professional Debut — Do Hyung Kwon
Yeon Kyun Kim made his professional MMA debut at GFC 05 on May 1, 2021.
Facing the considerably more experienced Do Hyung Kwon in a 172-pound catchweight contest, Kim was caught in an armbar at 2:38 of Round 1.
It was an unsuccessful debut, but Kim would rebound in his next appearance.
First Professional Victory
Yeon Kyun Kim returned at GFC 07 on January 29, 2022, facing professional debutant Sung Yoon Kim.
This time, God Gyun completed the scheduled two rounds and earned a unanimous decision victory.
The result evened his professional record at 1–1 and demonstrated his ability to compete effectively over a longer fight.
Black Combat Debut — Hyun Woo Jeon
Kim entered Black Combat through its Champions League system on October 1, 2022.
His first assignment came against debuting Hyun Woo Jeon in the main event of the opening week of the 2022–23 Champions League season.
Yeon Kyun Kim produced his most decisive professional performance.
He submitted Jeon with a rear-naked choke just 1:03 into the opening round, giving him consecutive victories and improving his record to 2–1.
It remains the only submission victory of Kim’s professional career.
Black Combat 6 — Jun Seo Choi
Yeon Kyun Kim’s consecutive victories earned him a major opportunity at Black Combat 6: The Final Checkmate on April 15, 2023.
He faced Jun Seo Choi in a middleweight contest at 185 pounds.
Choi represented a significant increase in competition. He entered with a 5–2 record and a considerable physical advantage, standing 6’0″ with a listed 78-inch reach compared with Kim’s 5’10” frame.
Kim survived the opening round, but Choi eventually broke through in the second.
Knees and punches forced the stoppage at 3:47 of Round 2, handing Kim the first striking stoppage loss of his professional career.
The defeat dropped God Gyun to 2–2.
Two-Year Absence
The Choi loss was followed by an extended period away from recorded professional MMA competition.
Yeon Kyun Kim would not return until June 2025—more than two years after Black Combat 6.
When he returned, there was one notable difference.
Kim was now competing at welterweight.
Return Against Gilberto Macedo
Yeon Kyun Kim returned at Black Combat Champions League 24–25: 12th Week on June 7, 2025, facing Brazilian Gilberto Macedo.
Macedo held a noticeable size advantage, standing approximately 6’1″ compared with Kim at 5’10”.
Kim was also the underdog among Tapology users, with only 23 percent selecting him to defeat Macedo.
God Gyun proved them wrong.
Kim completed all three rounds and earned a unanimous decision victory, improving his professional record to 3–2.
The result was significant for several reasons.
It ended more than two years of inactivity, returned Kim to the win column after his loss to Jun Seo Choi and demonstrated that he could successfully compete at the 170-pound welterweight limit.
It also marked his first professional victory over an international opponent.
Sander Silva — BnD Black Cup
Yeon Kyun Kim’s most recent appearance came on April 11, 2026, when he faced undefeated Brazilian Sander Silva at BnD Black Cup: Mongolia vs. China.
Again, Kim faced a considerably taller opponent.
Silva stood 6’2″, giving him approximately four inches of height over the 5’10” Korean.
Silva entered 2–0 professionally and was heavily favored by Tapology’s community predictions, receiving 93 percent of the picks.
Unlike Yeon Kyun Kim’s previous fight against Macedo, there would be no upset.
Kim nevertheless survived the full 15 minutes before losing by unanimous decision.
The result dropped his professional record to 3–3, while Silva improved to 3–0.

Summary & Trajectory
Yeon Kyun Kim is still a relatively difficult fighter to define.
Six professional fights are enough to establish some patterns, but not necessarily enough to determine his ceiling.
His career began with a submission defeat against an experienced opponent, followed by consecutive victories that showed two different aspects of his game. He could win rounds, as he demonstrated against Sung Yoon Kim, but he could also capitalize on grappling opportunities, as shown by his rapid rear-naked choke against Hyun Woo Jeon.
The Jun Seo Choi fight represented his first significant test against an established Black Combat opponent.
It also exposed some limitations.
Choi’s combination of size, reach and striking ultimately overwhelmed Kim in the second round. Considering that the matchup took place at middleweight, however, it also raised the question of whether Kim was competing above his most natural division.
His return at welterweight offered a more encouraging answer.
After more than two years away, Kim defeated Gilberto Macedo over three rounds despite entering as the underdog. He then faced another Brazilian opponent in undefeated Sander Silva and, although he lost the decision, remained in the fight for the complete 15 minutes.
That leaves Yeon Kyun Kim at an interesting point in his career.
He is 3–3, but two of those defeats came against Jun Seo Choi and Sander Silva—opponents who entered their fights with considerably stronger records than Kim’s previous competition.
His record therefore needs some context.
Yeon Kyun Kim isn't a fighter whose record immediately demands attention.
At 3–3 with no knockout victories, God Gyun has yet to demonstrate the type of dominant offensive weapon that typically separates prospects from the larger regional field.
But there are reasons not to dismiss him based solely on the numbers.
The first is the progression of his opposition.
Kim's first victory came against a debuting opponent. His next Black Combat victory was also against a debuting fighter. Since then, the level has increased considerably.
Jun Seo Choi entered their fight 5–2.
Gilberto Macedo presented Kim with an international opponent and significant physical size.
Sander Silva entered undefeated and stood 6'2" against the 5'10" Kim.
Kim went 1–2 across those three fights, but the Macedo victory demonstrated that he is capable of beating opponents who appear to have physical or stylistic advantages.
The second encouraging development is his move to welterweight.
Kim fought Jun Seo Choi at 185 pounds despite standing only 5'10". He subsequently returned at 170 pounds and immediately earned a unanimous decision victory.
That doesn't automatically mean welterweight solves every problem, but it provides a more logical physical framework for his game.
There are still clear limitations.
Kim has yet to record a knockout, and his only professional submission came against a debuting opponent. Against stronger competition, he has not consistently demonstrated an offensive weapon capable of changing the direction of a fight.
That is the next step.
If Kim can combine his existing grappling and ability to compete through three rounds with more effective finishing offense—or simply become better at converting positional control into damage—his ceiling changes considerably.
For now, HanPunch should view Yeon Kyun Kim as a developing Korean regional welterweight rather than an established prospect.
His 3–3 record accurately reflects some of the uncertainty surrounding him, but it doesn't tell the entire story. God Gyun has gradually moved from inexperienced domestic opposition into legitimate Black Combat and international matchups, and he has shown enough durability and versatility to remain competitive as that level has increased.
At this point, the most important part of Kim's career may be what comes next.
Now apparently settled at welterweight and with six professional fights behind him, his next few performances should reveal whether God Gyun is developing into a meaningful player in Black Combat's 170-pound division—or settling into the role of a dependable regional veteran.
