What they lack in size and strength, Tatterdrakes make up for in aggression and ferocity. Any perceived threat is seen as a challenge and met with complete hostility; fights for territory are so commonplace that many older Tatterdrakes possess wings so ripped from fighting that they can no longer fly. Tatterdrakes are exclusively solitary except when they are seeking mates, for which they also clash.

Though it may appear at first that dragons and drakes have much in common, the two are completely separate species. Drakes are smaller and less intelligent than their cousin species, though both dragons and drakes sit comfortably near the top of the food chain. They are always found bearing antlers and leathery wings. Drakes share many of the same habitats that dragons do, and typically hunt in packs.

Yuk-Yuk is so aggressive and fights so much that the other dragons of the cave gave him his own little area of land inside. It's small, but Yuk-Yuk seems to be happy with it. Any dragon that walks in his area is often fought, so people stay away from him.
