It is a bipedal breed, metallic grey in colour, with an immense wingspan, long talons and rough scales. It is the largest breed of dragon which reaches up to six tons, and its eyes are deep red. Sometimes the eyes seem to be the same colour as its body because of a protective scale.
Rotund and slower in flight than other dragons, the Ironbelly is nevertheless extremely dangerous, capable of crushing dwellings on which it lands.
