Most people remember the flashy stages, the yellow "reboot" buttons, and the high-stakes drama of the 2017 survival show. But honestly, if you look at the cast of The Unit today, the story isn't just about who won. It is about a group of industry veterans who were told they were "washed up" at 22 and decided to fight back anyway.
The K-pop industry is brutal. It moves fast. If your debut doesn't hit the top of the charts within twelve months, labels often check out mentally. They stop booking the variety shows. They stop paying for the high-end music videos. This show was supposed to be the "Idol Rebooting Project," a lifeline for people like Jun from U-KISS or Euijin from Sonamoo. It was a fascinating, often heartbreaking look at what happens when the dream starts to fade.
Who Actually Made the Final Cut?
The final lineups were named UNB (for the guys) and UNI.T (for the girls). It’s kind of wild looking back at the sheer amount of talent concentrated in those final nine-member groups.
For the men, Jun (Lee Jun-young) took the top spot. He was already a member of U-KISS, but The Unit catapulted him into a different tier of fame. He wasn’t just a rapper anymore; he proved he could carry a show. Then you had Euijin from Bigflo, who brought a level of professional dance skill that genuinely intimidated the younger contestants. The rest of UNB included Feeldog (Bigstar), Hangyul (IM), Ho-jung (Hotshot), Ji Hansol (Newkidd), Chan (A.C.E), Marco (H.B.Y), and Kijung (IM66).
The women's side, UNI.T, was equally stacked with "should-have-been" stars. Euijin from Sonamoo grabbed the first-place trophy, followed by Yebin (DIA), NC.A (a solo artist), Yoonjo (formerly of Hello Venus), Hyunjoo (formerly of APRIL), Yang Jiwon (formerly of Spica), Woohee (Dal Shabet), ZN (Laboum), and Lee Suji (formerly of The Ark).
If you’re a long-time K-pop fan, those names carry weight. Spica and Dal Shabet were groups with massive vocal power that just never quite hit the "Twice" or "Blackpink" level of commercial dominance. Seeing them on stage together was like a fever dream for second and third-generation stans.

Well, it's complicated.
UNB and UNI.T didn't become the next BTS or Twice. They just didn't. Contractual limitations and the temporary nature of the project meant they had a shelf life from the very beginning. UNI.T debuted with "No More," a reggae-inspired track that was actually quite sophisticated, but the promotion period felt rushed. By the time they released "I Mean," they were already saying goodbye.
But if we measure success by individual longevity, the cast of The Unit actually fared better than many give them credit for.
Lee Jun-young is the gold standard here. He transitioned into a full-blown A-list actor. If you’ve seen D.P., Mask Girl, or Love and Leashes on Netflix, you’ve seen Jun. He’s no longer "that guy from the reboot show." He’s a respected actor who just happens to be able to dance circles around most people.
Then look at Lee Hangyul. He didn't just stop at UNB. He went on to Produce X 101, made the final lineup of X1, and eventually debuted in BAE173. The man is a survival show veteran. He’s the personification of "not giving up," even when the industry throws every possible hurdle in his way.
Why Some Members Faded and Others Soared

Some members returned to their original groups only to find the momentum had stalled. Laboum, for instance, had a late-career viral hit with "Journey to Atlantis," but that happened years after ZN (now known as Jin-ye) appeared on The Unit.
Others, like Yang Jiwon, faced the harsh reality of the "idol age limit." Jiwon was already a legend in the trainee world—she was part of the original Five Girls lineup with G.Na, Uee, Hyoseong, and Yubin. By the time she got to The Unit, she was working part-time jobs delivering juice. Her story was the emotional heart of the show. While UNI.T didn't last forever, she proved she still had the "it factor," later moving into musical theater where her powerhouse vocals could actually be appreciated.
The Problem with the "Reboot" Narrative
There is a common misconception that The Unit was a failure because the groups disbanded.
That misses the point.
The show was a massive marketing campaign for talent that had been buried by poor management or bad luck. For someone like A.C.E's Chan, the show provided a platform that helped his home group, A.C.E, build a dedicated international following. They became one of the most successful "underdog" stories in the industry, touring the US and Europe extensively. Without the exposure from the cast of The Unit, that path would have been significantly steeper.
The show also highlighted the "Hotshot curse." Hotshot is a group that featured Taehyun and Sungwoon (who went to Produce 101 and Wanna One) and Hojung and Timoteo (who went to The Unit). They were arguably one of the most talented groups in history, yet they could never quite get all the members in the same room at the same time due to different project group schedules. It’s a cautionary tale for small agencies.

Behind the Scenes: What Fans Didn't See
Life in the dorms during filming was notoriously exhausting. Participants have mentioned in later interviews and vlogs that the pressure to "prove" they weren't failures was immense.
Unlike Produce 101, where trainees are often teenagers with nothing to lose, The Unit contestants were adults. They had bills. They had younger trainees looking up to them. They had parents who had been waiting for a "win" for five or six years.
Rain, who served as the lead mentor, was often criticized for being harsh. But his "tough love" came from a place of knowing exactly how fickle the public is. He knew that for 90% of those on the stage, this was the absolute last chance a major network would ever give them.
The Impact on the 2026 K-Pop Landscape
Looking at the industry today, we see the fingerprints of The Unit everywhere. The trend of "second-chance" shows has exploded. Shows like Peak Time or Build Up owe their entire format to the groundwork laid by the 2017 cast.
We now accept that an idol's career doesn't have to end at 25.
We see Yoonjo getting married and still being celebrated by fans. We see Euijin (the male winner) transitioning into a successful solo career and choreography. We see the "Unit" family still hanging out—members from different groups who would have never met otherwise are now best friends.
Actionable Takeaways for Fans and Collectors
If you're looking to dive back into this era or support the members now, here is how you actually do it without getting lost in the "disbanded" gloom:
- Follow the Acting Pivots: If you liked the charisma of the cast, follow their drama careers. Beyond Jun-young, members like Suji and Woohee have built solid filmographies. Their acting often mirrors the discipline they learned as idols.
- Check the "Post-Unit" Discographies: Don't just stop at the show's songs like "Question" or "You & I." Look for the solo work of NC.A or the later releases of A.C.E. This is where the real artistry came out once the pressure of the competition was off.
- The Second-Gen Connection: Use The Unit as a map to discover older groups. If you liked Yang Jiwon, go listen to Spica’s "Tonight." If you liked Jun, go back to U-KISS’s "0330." It provides a much richer context for why these artists were so desperate to stay in the game.
- Support Current Ventures: Many members have moved into fashion, YouTube, or dance academies. Feeldog, for example, is an incredible artist (painting) and dancer. Following their personal brands is the best way to support them in 2026.
The legacy of the cast of The Unit isn't found in trophy cases or chart records. It is found in the fact that almost every single person in that final lineup is still working in the creative arts today. In an industry that tries to discard people as soon as they hit a certain age, that is the ultimate "reboot." They didn't just win a show; they won the right to keep going.
