Nameless

Villains, families, species, or groups whose real given names remain unknown if they had one to begin with (e.g. The Thing), were simply forgotten (e.g. Witch-King of Angmar), are unpronounceable by conventional language (e.g. Glgrdsklechhh) or are known only by aliases or conjectural names (e.g. Fiamma of the Right, Right Hand Man). Such villains can be Enigmatic.
