Storm Dragon
From Flexible Survival
The infection commonly known as the Storm Dragon doesn't look especially dragonlike to many people, but some claim that it is in fact a nanite-born mimicry of a type of true (supernatural) dragon, one born of elemental storm energy. Of course, it might just be yet another bizarre creation of the nanites patching random bestial and human traits together. No one really knows.
