Park Gun-wook
Rapper, dancer, vocalist, former survival-show giant baby, and now the first current member to put writing, composition, and arrangement together on a ZEROBASEONE group track.
Early life and training
Gun-wook trained under Jellyfish Entertainment and appeared on the 2021 survival program Wild Idol before joining Boys Planet. That earlier show emphasized physical competition and performance toughness, creating the “powerhouse” image that followed him.
He attended school in Osan and was known for strong academics and leadership alongside performance training. The contrast became part of his appeal: physically imposing onstage, articulate and analytical when explaining music, and still one of the younger members in the final lineup.
Boys Planet: how he reached the lineup
Gun-wook entered Boys Planet with confidence that some viewers initially read as intimidating. Survival editing loves a simple label, and “big confident trainee” is easier to package than a teenager calculating how to survive another public competition.
His stages gradually showed more range—rap, dance, vocals, team leadership, and emotional openness. He finished fifth and joined ZEROBASEONE, turning a polarizing first impression into one of the show’s clearest growth arcs.
Career with ZEROBASEONE
Park Gun-wook debuted with ZEROBASEONE on July 10, 2023 through Youth in the Shade and “In Bloom.” The original nine-member run moved quickly: multiple million-selling releases, Korean and Japanese promotions, award shows, tours, brand work, and a fandom that always knew the project clock was running.
ZEROBASEONE used Gun-wook as a performance anchor and rapper, but he also proved capable of stable vocals and softer delivery. The creative breakthrough arrived with Ascend-: he received lyrics, composition, and arrangement credits on “Customize,” created with the five current members’ voices and strengths in mind.
When the original term ended in 2026, Gun-wook remained in the continuing five-member ZEROBASEONE with Sung Han-bin, Kim Ji-woong, Seok Matthew, and Kim Tae-rae. Their first mini album in that formation, Ascend-, deliberately moved toward contemporary R&B, groovy hip-hop, and a more mature performance style.
Skills, voice, and stage identity
Gun-wook combines size, speed, and musical intelligence. His dancing can look explosive without losing the beat, and his rap lands best when producers let him use weight and rhythm instead of squeezing him into novelty bars. He is also a stronger vocalist than the “rapper” label suggests.
What to watch
- Dynamic control: he can move from full-force choreography to a small groove without looking switched off.
- Rap placement: his best parts connect sections instead of stopping the song for a rap break.
- Creative credits: “Customize” is the starting point for tracking what his own musical taste adds to the group.
Era map
- “In Bloom”: the bright debut image and the pressure of arriving with a built-in ending.
- “CRUSH” and “Feel the POP”: heavier performance work followed by playful summer-pop precision.
- “GOOD SO BAD” and “BLUE”: stronger vocal identity and more confident camera work.
- “LOVEPOCALYPSE”: the emotional closing stretch of the original nine-member chapter.
- “TOP 5”: the first clean introduction to the five-member era. He grounds the rap passages and makes the mature groove feel lived-in rather than borrowed for one comeback.
Fandom file
Fans often pair Gun-wook’s imposing stage presence with “giant baby” language because he was one of the youngest original members. That joke is fine until it hides the serious part: he studies performance, speaks thoughtfully about arrangement, and used the first five-member album to claim authorship. He currently has no confirmed personal Instagram; use the group’s verified channels.
The important line between useful fandom detail and nonsense is evidence. Nicknames, habits, and inside jokes belong here when they are traceable to broadcasts, interviews, or the member himself—not because a random graphic with seven fonts repeated them.
Current chapter
Gun-wook said the first five-member album would feel more meaningful if it included a member-made song. “Customize” is the evidence. The next question is whether that credit becomes a recurring part of ZEROBASEONE’s sound or remains a special album story. Either way, it gives the new era something more valuable than a visual reset: a member helping write the direction.
