Druddigon is a large, blue, hunchbacked, reptilian creature with medium-sized wings shaped like thistle leaves. It has a set of glaring, ferocious pale yellow irises. Its arms are longer than its legs, giving it a low-slung, sloping gait. It has a thick, medium-length tail and sharp claws on both the hands and feet. Its head is coloured bright red, and has several blunt horns and spikes jutting out everywhere. It also has tall, conical spikes—similarly coloured red; three on each arm, one on each shoulder, two on each leg, and four on its tail. It has a blunt, brutal snout, bearing a maw with no discernible teeth; instead, small fang-like protrusions sprout from its jaws. It has a series of olive-colored, football-shaped scutes running across its belly.
