My personal favourite, the Frost dragon likes cold climates so it migrates every year from the Arctic to the Antarctic. It lives in sea facing faces it hallowed out from glaciers and perfectly blends into its enviroment with its white (sometimes tinged with blue or pink) pigment. It is 40 feet long and 12 to 15 feet high and with its large wings, can easily launch itself into the freezing Arctic (or depending on the season, Antarctic) air. Using its fearsome frosty breath, (that freezes thing immediately) tail, claws, and horns, it can hunt giant squids, polar bears, and walruses easily.
