Dark Entity is an artist's impression of an insect-like alien and is based on reports from eye witnesses. The Dark Entity is usually accompanied by smaller gray entities, and always appears to be in charge or in control of the smaller entities. The Dark Entity stands six to seven feet in height, and has a build and posture closely resembling that of a praying mantis. Its exoskeleton is reasonably rigid, somewhat glossy, and is predominantly black with a subtle blue tint. The Dark Entity is relatively rare, though sightings of it have been reported world-wide. It is usually seen motionless in darkness or shadows on the other side of a threshold, though broad-daylight sightings of the entity have been reported, as well as outdoor encounters in rural settings.

Human Reality is an artist's impression of a scene recalled during an encounter near Casa Grande, AZ. In November of 1993, under an obscure overpass along I-10. At one point during the encounter, a yellowish skinned entity quivered as it made this expression, which was taken as irritation or protest. Accounts of expression are relatively rare among encounter experiences.
