KOYA is a cute blue koala bear and one of the eight main characters of the BTS BT21. KOYA is known as a smart, multi-talented, brilliant, and sleeping cutie of the BT21 group. This sleepy blue koala bear has removable ears and a big purple nose. BTS V once said that Koya has a purple nose because purple resembles love and that KOYA is a sleepyhead. When shocked in his sleep, KOYA wakes up and his ears fall off. Before joining the group KOYA lived peacefully in the forest with his friends LEAF, BAEBY, and TOLL, but BT21 TATA invited him to join.
