Devidian

Devidians in their true form

Devidians were a vaguely humanoid, shapeshifting species native to Devidia II. Their physical characteristics composed of being between 2 and 3 meters in height; they had no apparent eyes but they possessed an orifice on what most humanoids would call their forehead, that resembled a mouth. They lived out of phase with most other lifeforms with a phase variance of 0.004. They also possessed the ability to travel through time.

Devidians' only useful form of nourishment was Human neural energy. They acquired this energy by draining the subject of their neural energy, killing the subject. They preyed on humans from 19th century San Francisco using the cholera epidemic at the time as a cover for their murders.

In 2369, the USS Enterprise-D fired modified photon torpedoes on the Devidians' cavern habitat to prevent them from further incursions. (TNG: "Time's Arrow", "Time's Arrow, Part II")

A Devidian costume was auctioned off in the It's A Wrap! sale and auction. The costume is a blue foam rubber body suit, with extremely wrinkled skin and a large cranial area, with the front of the cranial area indented. Although the costume has five fingers, the feet have six toes.

Apocrypha

In Star Trek Online, set forty years after "Time's Arrow", the Devidians return in a five-part feature episode series, where they have been spotted in the re-established Klingon Neutral Zone. Player captains of both the Federation (working for Section 31) and the Empire (working for Klingon Intelligence) are sent to investigate.
