A type of extra terrestrial being (alien). Usually the most common amongst alleged abductees. Also the type most commonly connoted with the Rosswell, New Mexico crash site.

Some believe Greys are of the same species of alien as Reptilian. This is debatable.
The Rosswell, NM crash site yielded several aliens. They were all Greys.
