It also introduced the dragonwrought kobold, one born with more draconic features than usual (functional wings, for instance).

The Precursor Hero Girard Draketooth, was a quarter dragon (his grandmother was human and his grandfather was a black dragon) and doesn't fit the trope himself, being completely human looking. However, an illustrated family tree indicates that one of his parents and his aunt and uncle did look the part, having varying mixtures of human and draconic features.
