Pseudo-Wyvern Drakes are a desert-dwelling species with an unusual bipedal body structure as adults. They start out as quadrupedal hatchlings and slowly start walking on their hind legs as they age. As their name suggests, these drakes are often mistaken for wyverns from afar as they ride the desert currents searching for food. A social drake, Pseudo-Wyverns travel in small packs, working, hunting, and raising young together.

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.

Since he was a hatchling, Kussetsu's inquisitive nature has been a bit of a double-edged sword. Whenever he and his family went out foraging, Kussetsu was always the first to volunteer to go poking around in suspicious burrows or rock crevices, even if there were venomous animals in the area. Kussetsu never had much of a sense of suspicion, as any nervousness he may feel about a situation tends to be overwhelmed by his much more powerful sense of curiosity. Fortunately, most of the time when he investigates an ambiguous location, he's usually found food or just nothing of interest. On the rare chance that he finds something dangerous, Kussetsu just immediately takes off running in the opposite direction.
