Chimuelo is a dragon that first appeared in How to Train Your Dragon: The Hidden World. The dragon is a mystical, legendary creature that appears in the folklore of many cultures around the world. Beliefs about dragons vary significantly from region to region, but dragons in Western culture since the Middle Ages have often been depicted as having wings, horns, and the ability to breathe fire. Dragons in Eastern cultures are often depicted as wingless, four-legged creatures with serpentine shapes and above-average intelligence.
