The Dramillion is a Mystery Class dragon that appeared in Dragons: Race to the Edge.
Official Description[]
Although normally withdrawn and wary of humans, Dramillions mimic the fire blast of any dragon they encounter. With their striking coloration, peaked crown, and curved beaks, Dramillions have often been called the parrots of the dragon world for these uncanny creatures can also repeat any kind of dragon fire they see. The Dramillion duplicates blasts that look — and burn — like the real thing. It's no wonder, then, that Dragon Hunters once forced Dramillions to reproduce their many fire forms for training drills. Dramillions have the highest shot count of any other dragon species by far. But even these copycats will hit empty after enough blasts. Fortunately, Dramillions can also transfer flames to each other. If one runs out of heat, the rest of its pack share their reserves with the spent Dramillion so it can fire up again!
