Koya — RM's Sleepy Blue Koala
Koya was designed by RM (Kim Namjoon) to reflect his own complex personality: extraordinarily intelligent, deeply thoughtful, but constantly exhausted. The blue koala's signature half-closed eyes have become one of the most recognisable expressions in the entire BT21 cast. Koya's colour palette — soft blues and greys — gives merchandise a calm, sophisticated aesthetic. The Koya BT21 collection includes plush in standard and mini formats, a 30cm pillow cushion, and keychain.
Koya is ideal for: fans of RM, people who prefer a more understated aesthetic, students who relate to the "genius who needs a nap" energy, and anyone who wants strong visual contrast with brighter characters like Cooky or Chimmy.
Tata — V's Shape-Shifting Alien
Tata was designed by V (Kim Taehyung) and is unlike any other character in BT21: a being from a distant planet who can reshape their heart-shaped head into any form. Tata reflects V's free-spirited, imaginative nature — unpredictable, deeply emotional. The purple and blue palette gives Tata merchandise a regal, distinctive look. Browse the Tata BT21 collection for plush in multiple sizes and keychain.
Tata is ideal for: V fans, people drawn to more unusual or fantastical designs, collectors who want something visually different from the animal characters, and anyone who loves a character with infinite possible forms. The Van BT21 collection also has a similarly unique concept if you love one-of-a-kind characters.
Koya vs Tata — Which to Choose?
Choose Koya if you or the recipient is an RM fan, prefer calm blue/grey aesthetics, identify with the “quietly brilliant but tired” energy, or want a character that works in a minimalist space. Choose Tata if you or the recipient is a V fan, prefer artistic or fantastical aesthetics, want a truly unique character in a BT21 collection, or are drawn to purple tones and otherworldly concepts. Both are available as plush, cushion and keychain — officially licensed, EU shipping.
