The power to use the abilities of a Grey Alien. Variation of Alien Physiology.


User with this ability either is or can transform into a grey, extraterrestrial being typically depicted as gray-skinned (sometimes muted blue or green, occasionally a beige) diminutive humanoid beings that possess reduced forms of, or completely lack, external human organs such as noses, ears or sex organs. Their bodies are usually depicted as being elongated, having a small chest, and lacking in muscular definition and visible skeletal structure. Their legs are shorter and jointed differently from what one would expect in a human. Their limbs are often depicted as proportionally different from a human's; their humerus and thighs are the same lengths as their forearms and shins, respectively.

The Greys aren't usually overtly hostile; abduction is their primary modus operandi (which naturally may be taken as still fairly sinister of course). They don't generally speak (or explain their motivations) much if at all. They may be telepathic.





  • Greys are generally physically weak.
