Grays, the

The Grays ,

aka the Earth ETs - The Grays had visited Earth so many times they became the quintessential Alien for Earthers. Humans of  Earth were disappointed when neither the Sarans, nor the Xunx looked like the Gray.

It turned out ,most of these sightings were Freons or Ferons.

The very tall Gray (pictured) were an off shot of the Freons and were exterminated alomg with their cousins by angry Earthers.

Note: No Biological data other than the incomplete disection data collected by Project Armadillo exists.
