Greys are a hypothetical alien species often associated with alien abduction stories, ufology and New Age beliefs - although such beings would normally not be considered villainous the Greys do deserve some notice for the fact that many encounters with these supposed creatures are said to be hostile, though some are more peaceful in nature.
Greys are generally believed to be untrustworthy and dangerous with stories involving attempts to crossbreed with humanity or working in alliance with Reptoids, another supposed alien species that is almost universally described as malevolent in regards to humanity - ever since reports of alien abduction became known to the public the idea of the Greys became an instant hit and they continue to fascinate people, though the debate still rages on whether or not they exist and if they are good, evil or beyond classification (the latter seems the most probable if they did exist).
Greys are also one of the theorised causes of the phenomena known as cattle mutilation and some also believe the Greys created (or helped to create) the Chupacabra - there are also more outlandish theories about Greys and humans interbreeding to create a new hybrid species, some believe Greys are unable to produce by themselves and are a dying species - perhaps explaining why they are so interesting in abducting humans.
More importantly in regards to villains the Grey have inspired a host of often hostile antagonists for movies, television series, comics and books as well as videogames and other media - though they often have different names and are depicted slightly different in each story.
According to some Greys are extremely untrustworthy and lie to their allies in hopes of outsmarting them, this coupled with their often emotionless mannerisms make them strange and sinister in the eyes of many.
Yet the idea of Greys being totally without emotion is conflicted by the fact that many reports state that Greys utilise strange psychic powers to try and calm victims of abduction (though they do not stop the intrusive surgery) - the fact the Greys try to calm their victims suggests that the cryptids (if they exist) have a softer side to their personalities.
There is also debate as to whether or not the smaller versions of the Grey are the same species as the taller ones, in general it seems the smaller Grey are servants to the taller ones and (in general) the taller Greys seem to be the most emotionless and sinister.
Some radical Christians believe that Greys are not aliens at all but actually part of a Demonic Conspiracy.
