After predicting a clean sweep before the five-on-five showdown, the Chan Sung Jung, Korean Zombie, watched ZFN leave with a 4–1 victory but his biggest takeaway had less to do with the final score than the interest the rivalry created around the fighters.
Chan Sung Jung arrived at the TFC Dream Center expecting five wins.
By the end of the night, ZFN had four.
It was still a convincing result for the promotion led by the former UFC title challenger. ZFN defeated TFC 4–1 in their five-on-five promotional showdown on August 30 in Gimpo, South Korea, winning the first four matchups before TFC salvaged the final bout.
But watching Jung’s own account of the event, the final score does not feel like the most important part of the night.
Before the fights, there was confidence. During them, there was tension. And afterward, there was a recognition that perhaps the rivalry itself had accomplished something useful for Korean MMA.
It made people care.
From 5–0 Talk to Fight Night
There was no attempt from Jung to hide his allegiance.
At the beginning of his video, the Korean Zombie explained that he had come to support ZFN and hoped his fighters would win every matchup.
Later, while running through the five ZFN representatives, his confidence became even clearer.
“Who is going to lose?” Jung asked while looking at the lineup.
Then came the nervous reality of being responsible for fighters rather than being the one competing himself.
“Please, please do well.”
The matchup itself carried more meaning than an ordinary collection of fights.
TFC represents an established part of Korea’s MMA infrastructure. Since 2014, the promotion has sent numerous athletes toward the UFC, while ZFN represents a much newer project under one of the most recognizable fighters South Korea has produced. Jung retired from competition in 2023 and has since turned much of his attention toward developing fighters and building ZFN.
There was history between the people involved, too. Jung previously trained under TFC and Korean Top Team head Ha Dong Jin during an earlier stage of his fighting career before eventually establishing Korean Zombie MMA and later ZFN.
So when the two organizations put five fighters against five fighters, the individual bouts suddenly carried another layer.
They were fighting for their promotion.
Jung Experiences the Other Side of the Cage
The most interesting parts of Jung’s video come once the fights begin.
For years, Korean fans watched him absorb the pressure of competing on some of MMA’s biggest stages.
At TFC Dream Center, he was experiencing a different kind of pressure.
Jung can be heard constantly reacting from cageside, calling for pressure, positional adjustments and hand fighting while celebrating successful sequences. At other moments, he simply sounds like someone desperately hoping the fighter he helped prepare can find a way to win.
ZFN kept doing exactly that.
The promotion took the first four fights of the five-on-five series before TFC’s Lee Seung Jun prevented the sweep in the heavyweight main event, leaving the final score at 4–1.
The predicted 5–0 never came.
What followed may have said more about Jung’s role as a promoter and coach than another victory would have.
“Don’t Be Disappointed”
After one of his fighters lost, Jung’s attention quickly shifted away from the scoreboard.
“Don’t be disappointed,” he told the fighter afterward. “You worked hard. Fighting like that isn’t easy.”
When the fighter apologized, Jung rejected the apology.
He told him he had genuinely fought well and encouraged him to believe that he could continue improving.
It was a small exchange, but one that showed the difference between promoting a rivalry and living with its consequences.
Beforehand, 5–0 makes a good prediction.
Afterward, there are still five athletes on the other side of that score.
And Jung’s final comments reflected that distinction.
The Rivalry Did Its Job
When Jung addressed the event at the end of the video, he acknowledged the provocative comments that had been made before the competition.
“Before the fights, we said a lot of provocative things, like that we would win 5–0,” Jung said.
But once the competition was finished, his message changed.
He praised the athletes from both organizations for competing in good faith and said he wanted to recognize how hard everyone had worked.
More importantly, Jung pointed toward the attention generated by putting two promotions against one another.
“I think people showed a lot of interest because it was an inter-promotional competition,” Jung said. “Isn’t it good for fighters to compete while receiving this kind of attention?”
That may ultimately be the most important observation to come out of ZFN vs. TFC.
Korean MMA does not lack fighters.
What developing fighters often need is a reason for audiences to become emotionally invested before they are already established names.
ZFN vs. TFC created one.
Instead of asking fans to watch five unrelated matchups, the format gave every fight a common thread. One fighter’s victory affected the score of the entire team. The next fighter entered carrying the result that came before him.
TFC had something to defend.
ZFN had something to prove.
And fans had a side to choose.
Something Worth Doing Again
The result also matters for ZFN.
Jung’s promotion is still young compared with TFC, having launched under his leadership in 2024. Walking into the home of an established Korean organization and winning four of five matchups gives ZFN’s developing roster a meaningful result of its own.
But Jung didn’t finish his video celebrating 4–1.
Instead, he talked about what came next.
He said he believed the competition had been a valuable experience for all of the fighters and expressed interest in creating another event like it in the future.
That wasn’t an announcement of ZFN vs. TFC II.
It was an acknowledgment that the idea worked.
The pre-fight predictions created tension. The promotional identities gave the fights stakes. And when it was finished, both organizations had put additional attention on fighters still trying to establish themselves.
Jung came to Gimpo looking for five wins.
He left with four.
But ZFN vs. TFC may have demonstrated something more valuable than a perfect score.
Korean MMA fans will pay attention when they are given a reason to choose a side.
