Cooky is a very strong pink bunny with a right ear bending down, his left triangle eyebrow is thick while the right normal one is thin. But he can't be always a good bunny from the BT21 team, sometimes he wants to be a bad guy. So, he came up with the idea of wearing a demon suit and holding Poseidon's trident. in our fanart BTS BT21 Cooky Demon Sticker.
