dragon girl
A female character with a dragon-like appearance.
For actual dragons, use the dragon tag instead (though there may or may not be overlap if personification/humanization is at play).
A particularly famous kind of dragon girl (or boy) is the Fire Emblem "manakete" or "mamkute" (マムクート); the games typically include at least one such character, often playable, who can transform from a human form into a full dragon, with the prominence of draconic features varying between each example. For ease of sorting, a separate "manakete" tag should not be made and all such characters should be sorted into the appropriate dragon-person tag.
