Overview
Eun Bin Choi is a South Korean bantamweight and featherweight mixed martial artist representing Team Finish.
Known by the nickname “Prison,” Choi has built an early professional résumé defined almost entirely by finishes, combining legitimate knockout power with a submission background.
As of 2026, Choi holds a 3-1 professional record, with all three victories coming inside the distance: two by KO/TKO and one by submission. He has yet to win a professional fight by decision.
Choi’s career has developed somewhat differently from that of a prospect who competes several times each year. He made his professional debut in 2020, did not record his second professional appearance until 2024, and has consequently accumulated relatively few professional bouts despite having competitive MMA experience dating back to at least 2017.
His most recent performance may also have been his most impressive. Returning to Black Combat in April 2026, Choi stopped Brazilian veteran Paulo Cunha with strikes in the first round, rebounding from the first professional defeat of his career.
Early Life & Background
There is little reliable public information regarding Eun Bin Choi’s childhood, education, or initial introduction to martial arts, so those details should remain unspecified in the HanPunch database rather than inferred.
What can be documented is that his competitive MMA background extends considerably further back than his professional record suggests.
Choi appeared at ROAD FC Central League 37 in September 2017, competing in an amateur bout against Jung Bin Choi. He later appeared in Black Combat’s developmental system at Black Combat Begins 01 in November 2023, where he lost a split decision to Hyun Soo Jung.
Those appearances show that Eun Bin Choi spent meaningful time developing at the amateur level before becoming more active professionally.
He has represented Team Finish throughout his documented professional career.
Fighting Style
Finishing-Oriented Striker
Eun Bin Choi’s professional results point toward an increasingly dangerous striking game.
His 2024 victory over Sang Ho Kim ended with a right straight at 2:24 of the first round, giving Choi his first professional knockout.
He reinforced that reputation in his 2026 return against Paulo Cunha. Choi attacked Cunha with leg kicks and punches before securing the TKO at 3:09 of Round 1.
With two striking finishes in his last three victories, Choi has demonstrated that his power is becoming one of the defining elements of his game.
Submission Ability
Eun Bin Choi’s striking should not overshadow the grappling component of his skill set.
His professional debut against Soo Hyuk Mae at GFC 03 ended with Choi securing an armbar at 4:31 of the opening round.
That result is significant when evaluating Choi as a prospect. His three professional victories have included an armbar, a knockout and a TKO, giving him documented finishing ability in multiple phases of MMA.
Offensive Mentality
The clearest characteristic of Eun Bin Choi’s professional career is his willingness to pursue the finish.
He has never needed the judges in a professional victory. All three wins have ended in the first round, and his only professional defeat also ended inside the distance.
That creates a relatively straightforward identity: Choi is not currently a fighter whose résumé has been built around controlling rounds. He has been at his best when creating exchanges and turning openings into decisive offense.
Professional Career
Eun Bin Choi made his professional debut against Soo Hyuk Mae at GFC 03 on August 1, 2020. He secured an armbar late in the first round, beginning his career with a submission victory.
After a lengthy gap between professional appearances, Choi returned against Sang Ho Kim at Fight Life Dream: Hidden Warriors on March 9, 2024.
Eun Bin Choi needed only 2:24 to finish the fight, landing a right straight for the first knockout victory of his professional career and improving to 2-0.
That performance led to an opportunity with Black Combat.
Eun Bin Choi faced undefeated prospect Hyuk Min Ji in the co-main event of Black Combat Rise 04 on August 10, 2024. Unlike Choi’s previous professional bouts, the fight extended deep into the third round. Ji ultimately handed Choi his first professional defeat with a ground-and-pound stoppage at 3:56 of Round 3.
The defeat was significant because it provided Choi with his first extended professional fight against another rising Korean prospect.
Choi subsequently returned at BnD Black Cup: Mongolia vs. China on April 11, 2026, facing Brazilian veteran Paulo Cunha at bantamweight.
He responded emphatically.
Choi stopped Cunha with strikes at 3:09 of the first round, improving his professional record to 3-1 and returning to the win column after nearly 20 months away from competition.

Summary & Trajectory
Eun Bin Choi is an emerging South Korean bantamweight whose limited professional record understates the amount of time he has spent developing in MMA. With competitive experience dating back to at least 2017, Choi has progressed from the Korean amateur circuit into professional appearances with GFC, Fight Life Dream and Black Combat.
His professional results have been decisive. Eun Bin Choi owns three victories with three finishes, including an armbar submission and two striking stoppages. His first-round TKO of Paulo Cunha in April 2026 was particularly important, demonstrating his ability to rebound from his first professional loss and immediately reestablish himself as a fighter to watch in Black Combat’s lighter divisions.
With only four professional bouts, Eun Bin Choi remains relatively unproven against the deeper levels of Korea’s bantamweight division. However, his finishing ability and continued development make his next stage particularly interesting. More consistent activity and stronger opposition should provide a clearer indication of where his ceiling lies.
Eun Bin Choi is a prospect whose 3-1 record requires more context than the numbers alone provide.
His professional résumé is small, but Choi is not entirely new to competitive MMA. His documented amateur history reaches back to 2017, and the considerable gaps between his professional appearances mean his experience cannot be measured simply by counting professional fights.
What stands out is his ability to finish.
Choi has shown three distinctly useful offensive weapons across his three victories: submission grappling against Soo Hyuk Mae, straight-punching power against Sang Ho Kim, and a combination of damaging leg kicks and punches against Paulo Cunha.
The loss to Hyuk Min Ji also provides valuable information. Choi entered that fight 2-0 and was pushed deep into the third round before being stopped. For a developing fighter whose previous professional victories had both ended in the opening round, that type of extended fight can be an important developmental experience.
His response was encouraging. Rather than returning tentatively following his first loss, Choi stopped Cunha in the opening round in his next appearance.
For HanPunch, the primary question surrounding Choi is therefore not whether he can finish regional-level opponents—he has already demonstrated that. It is how those weapons translate as Black Combat increases the level of competition.
At 3-1, it is too early to label him among Korea's elite bantamweights. But a 100-percent finishing rate, experience in both striking and submission situations, and a successful 2026 return give Choi enough upside to make him a prospect worth monitoring closely.
HanPunch views Eun Bin Choi as a developing Black Combat bantamweight with legitimate finishing ability and considerably more to prove—the kind of fighter whose next two or three matchups should tell us far more about his long-term ceiling than his first four professional fights have.
