In 2017, BTS walked into LINE FRIENDS' headquarters with sketchbooks and came out with one of the most beloved character universes in the world. What began as a creative experiment became BT21 — eight characters, eight stories, one global phenomenon. Here's the full story of how it happened.
The Beginning — How BT21 Was Born
The collaboration started with a simple but bold idea: let BTS members design their own characters from scratch, without creative constraints. LINE FRIENDS — the brand behind global icons like Brown and Cony — invited the seven members to their studios and gave them free rein.
Over several creative sessions, each member drew their character, wrote the backstory, and defined the personality. This wasn't a licensing deal where a group's face is put on pre-existing merchandise. BTS genuinely built the BT21 universe, with LINE FRIENDS providing the design and production expertise to bring each character to life.
The line launched in September 2017. The response was immediate and overwhelming: LINE FRIENDS stores worldwide sold out within hours. ARMY had found a new way to connect with their favourite members — not just through music, but through characters that carried something real about each person who created them.
The Characters and Their Stories
Each BT21 character is a creative self-portrait of the BTS member who made it.
Cooky (Jungkook) — a pink bunny who looks soft but has fierce determination, always training to get stronger. Tata (V) — a heart-faced alien from planet BT who can shapeshift, as unpredictable and creative as V himself. Chimmy (Jimin) — an endlessly enthusiastic yellow puppy who never takes off their hoodie. Koya (RM) — a sleepy koala-like genius, deep in thought even when it looks like they're napping.
RJ (Jin) — a fluffy alpaca who loves cooking and caring for others, Jin's nurturing warmth made physical. Shooky (Suga) — a rebellious cookie who refuses to be eaten, sharp on the outside, soft within. Mang (J-Hope) — a masked horse who lives for dancing, expressive and mysterious. And Van — the guardian robot created by all seven members together, protecting the BT21 universe just as BTS and ARMY protect each other.

BT21 Today — The Global Impact
Nearly a decade on, BT21 is one of the most recognised character brands in the world. The characters have appeared in LINE FRIENDS pop-up stores on every continent, in brand collaborations spanning food, fashion, and lifestyle, and in the everyday lives of fans from Seoul to Paris to São Paulo.
What makes BT21 culturally durable is the emotional architecture behind it. For ARMY, a Cooky plush is not just a toy — it's Jungkook's creative vision in tangible form. That connection is impossible to replicate with generic merchandise, and it's what has kept BT21 relevant through years of shifting pop culture trends.
BT21 Merch Culture — Why Fans Collect
Within the ARMY community, collecting BT21 is an act of fandom and self-expression. Most fans start with their bias's character and expand from there — building a shelf that tells the story of who they love and why. Limited editions, seasonal drops, and collaborations like the upcoming McDonald's 2026 collection give serious collectors new reasons to engage regularly.
Authenticity matters. Official BT21 products carry the LINE FRIENDS label, precise stitching, and proper packaging. At bt21shop.com, every product is officially licensed and shipped across Europe — no customs surprises, no quality compromises.
