Grey aliens, popularized in mass media, are often considered the archetypal idea of an alien. Reported alien abductions often describe aliens with features similar to that as the Greys, and this popularity has lead to countless homages, parodies, and nods to the idea of grey-skinned alien visitors.



There are many variations of the Greys, although there are slight variations depending on which universe the alien is in they typically share the same basic traits.

  • Enlarged black eyes.
  • Shrunken almost non-existent nose.
  • Swollen enlarged cranium.
  • Grey Skin (typically the trait most changed).
  • Lack of lips.
  • Nudity (not always true)


Greys are most often associated with the idea of alien abduction (a trope that is often repeated in fiction), as well as cattle and livestock mutilations. It is unknown when exactly the idea of the Greys rose to prominence, but it is often associated with the Betty And Barney Hill Abduction.


What is not typically known is that 12 days prior to the alleged abduction an episode of The Outer Limits aired entitled "The Bellero Shield" with an alien remarkably like the one Betty and Barney Hill described while under hypnosis. Assuming that the Hills watched this episode, it could mean that this alien was the initial inspiration for the Greys.


In reality, according to The Alien Races Book by Dante Santori and Petro, the Greys are actually called the Solipsi Rai, a two billion year old race from the constellation Cygnus and is led by one leader named Ymartyyn. The race is often confused with other races such as the Maitre and the Zeta Reticulai (the abductors of Betty and Barney Hill) due to similar appearance. They are a peaceful and harmless race that have no colonies and focus more on the development of other planets and races. They do however have one powerful weapon to protect themselves from invaders and is capable of destroying entire ships. One of their ships is responsible for the Roswell incident on July 7, 1947. They have also stated that the human race still has 645 options for the future of their planet, with the correct options depending on their ability to develop space travel.

Reported SightingsEdit


As mentioned the prominence of the concept has lead to the widespread usage of the aliens.
