Overview
Jun Seok Kim (김준석) is a South Korean mixed martial artist known by the nickname “Terminator.”
A longtime competitor within the ROAD FC system, Jun Seok Kim has competed professionally since 2018 and has built the majority of his career against domestic opposition under the ROAD FC banner.
Born on April 2, 1999, Kim stands 5’5″ and has competed from flyweight through featherweight, although bantamweight has become his primary division. Tapology lists his professional record at 3-5 with one no contest, while FightMatrix lists him at 4-5 because of differences in how modified-rules bouts are classified.
Unlike many fighters whose victories are defined by finishing ability, Kim has built his success around rounds, pace and decision-making. All three victories recognized by Tapology and Sherdog have come by decision.
That makes Jun Seok Kim a different type of fighter from many of the prospects in the Korean regional scene. His effectiveness is generally measured less by one decisive weapon and more by his ability to remain competitive across extended fights.
Early Life & Background
There is little verified public information regarding Kim’s childhood or his introduction to martial arts, so those details should remain unspecified rather than inferred.
His documented competitive career, however, began well before his professional ROAD FC run.
Kim competed in the ROAD FC Central League amateur system as early as 2017. His documented amateur appearances include a second-round TKO of Dima Son in November 2017 and a victory over Jung Hyun Park at Road FC Central League 40 in March 2018.
Those appearances are important because they demonstrate that Kim developed through ROAD FC’s amateur infrastructure before becoming a regular professional competitor for the organization.
Kim made his professional debut several months later at KAISER 00: Genesis in July 2018, defeating Jong Min Jung by unanimous decision.
After a lengthy period away from recorded professional competition, Kim returned in 2022 and began the more active phase of his MMA career.
Fighting Style
Pace and Decision Fighting
Jun Seok Kim’s professional record gives a clear indication of how he wins fights.
All three of his officially recognized professional victories have come by decision. He has zero recorded professional knockout or submission victories, making him primarily a round-winning fighter rather than a traditional finisher.
His success therefore depends heavily on maintaining activity, controlling exchanges and accumulating enough effective offense to separate himself on the scorecards.
Experienced in Extended Fights
One of Jun Seok Kim’s strengths is familiarity with fights that reach the judges.
Seven of his eight official professional wins and losses have required a decision or reached deep enough into the fight to test his pacing and composure. His résumé includes two- and three-round bouts across ROAD FC and international competition.
That experience can be valuable against opponents accustomed to securing early finishes.
Versatility Across Weight Classes
Jun Seok Kim has competed across a surprisingly broad range of weights.
His professional résumé includes appearances at flyweight, bantamweight, featherweight and catchweights between divisions.
At 5’5″, Kim’s physical dimensions appear most naturally suited to the lighter divisions, and bantamweight has become the primary home for the later portion of his career.
Areas for Development
The same statistics that define Jun Seok Kim’s strengths also reveal his primary challenge.
Without consistent finishing ability, Jun Seok Kim often operates with a smaller margin for error. A fighter who regularly goes to the judges must consistently win rounds, meaning one poor round or positional mistake can determine the outcome.
That issue has become increasingly relevant during his recent losing streak, with two of his last three defeats coming by unanimous decision.
Professional Career
Jun Seok Kim made his professional debut against Jong Min Jung at KAISER 00: Genesis on July 21, 2018. He completed two rounds and earned a unanimous decision, beginning his career at 1-0.
Nearly four years passed before his next recorded professional appearance.
Jun Seok Kim returned at ROAD FC 60 in May 2022, dropping to flyweight to face Jin Woo Park. The return did not go as planned, as Park stopped Kim with punches at 1:54 of the opening round.
Jun Seok Kim remained within the ROAD FC system and subsequently competed in a modified-rules bout against Jung Won Wi at ARC 008. Kim won by unanimous decision, but Tapology does not include the result in his official professional record because the contest featured a 30-second ground limit.
He returned to standard professional competition against Min Hyuk Cha at ROAD FC 63 in February 2023.
Kim earned a unanimous decision over two rounds, improving his official professional record to 2-1.
His next appearance came against Min Hyung Han at ROAD FC 66. The fight was closely contested, with Kim ultimately losing by split decision after two rounds.
Kim then traveled to Japan for TOP BRIGHTS 01 in January 2024, where he faced undefeated Koshen Akanov. The bout was eventually recorded as a no contest after Akanov missed weight.
Jun Seok Kim returned to ROAD FC three months later and produced one of the better results of his career.
Facing experienced veteran Jae Nam Yoo at ROAD FC 68, Kim completed three rounds and earned a unanimous decision, improving his record to 3-2.
Since that victory, however, Kim has encountered the most difficult stretch of his professional career.
He lost a unanimous decision to Yoon Soo Han at ROAD FC 70 in October 2024 before traveling to India and dropping another unanimous decision to Punyajit Likharu in the main event of Aturto 2.3 that December.
Jun Seok Kim returned against Young Chan Choi at ROAD FC 74 in September 2025. Choi secured a ninja choke 37 seconds into the second round, handing Kim his third consecutive defeat.
A scheduled March 2026 bout against Ji Kyung Kim at ROAD FC 76 was subsequently cancelled, leaving Kim’s record at 3-5 with one no contest.

Summary & Trajectory
Jun Seok Kim is an experienced South Korean bantamweight who has spent much of his career developing within the ROAD FC system. Beginning with the promotion’s amateur Central League before becoming a regular professional competitor, “Terminator” has accumulated experience against a wide range of Korean and international opposition.
Kim’s career has been defined more by consistency and round-winning ability than finishing power. All three of his officially recognized professional victories have come by decision, including ROAD FC wins over Min Hyuk Cha and Jae Nam Yoo.
Recent results have been more difficult. Losses to Yoon Soo Han, Punyajit Likharu and Young Chan Choi have left Jun Seok Kim on a three-fight skid, while a planned return against Ji Kyung Kim in March 2026 was cancelled.
At 27 years old, however, Kim remains young enough to rebuild. His experience within ROAD FC and comfort in extended fights provide a foundation, but developing more threatening offense will likely be important if he is to move beyond his current position in Korea’s competitive bantamweight scene.
Jun Seok Kim is a fighter whose record accurately reflects both his strengths and his limitations.
The positive is experience.
Despite being only 27, Kim has documented competition dating back to 2017 and has spent years within the ROAD FC developmental system. He has competed at multiple weights, fought internationally and experienced almost every type of result a developing fighter can encounter.
His victory over Jae Nam Yoo is particularly useful when evaluating his potential. Yoo entered that matchup with considerably more professional experience, yet Kim successfully navigated three rounds to earn a unanimous decision. It demonstrated that Kim can compete effectively with seasoned regional opposition when he is able to establish his preferred pace.
The concern is equally clear: Kim has not demonstrated a reliable finishing threat at the professional level.
All three of his victories have gone to the scorecards. That does not inherently make him ineffective, but it means Kim frequently needs to outperform an opponent for the majority of a fight rather than having a weapon capable of immediately changing its direction.
His recent results illustrate the difficulty of that approach. Three consecutive defeats have dropped Kim from 3-2 to 3-5, including back-to-back unanimous decisions followed by the submission loss to Young Chan Choi.
For HanPunch, the next stage of Kim's career is therefore less about whether he has enough experience and more about whether he can turn that experience into a more dangerous offensive identity.
Improved finishing ability does not necessarily mean becoming a knockout artist. A stronger submission threat, more damaging striking, or an ability to convert positional advantages into sustained offense could all reduce his dependence on close rounds and judges' decisions.
HanPunch views Jun Seok Kim as an experienced ROAD FC bantamweight currently at an important point in his career. He has already proven that he can compete at the Korean regional level, but his next step requires more than simply remaining competitive. If “Terminator” can add a legitimate finishing dimension to the durability and decision-fighting experience he already possesses, there is still time for him to reshape the direction of his career.
