The Greys

The Grey is an Organic robot clone species created on both sides of the Galactic war as workers, soldiers, and every other aspect needed in a civilization. The Greys are most known for their human abductions; together with the Draco and Mantis, they are regarded as Demons in religion and folklore. The DNA used to create these beings came from the Zeta Reticuli, who were descendants of the original greys from the Orion arm
