This huge heart-headed character from BT21 is Tata, an alien with transforming powers with limbs that can bend and stretch into weird lengths and shapes. As you could already know, he's a character that Kim Tae-Hyung has been drawing for some time. Somebody thinks he is heartless due to his facial expression all the time. But here he shows that he has a heart in this fanart BTS BT21 Tata Holds a Heart Sticker.
