Demasturbot

The Demasturbot is an extrapederastrial species, known by hunting of other dangerous porn addicted species, including mammalians, humans and avian cyborgs.

The adult phenotype is generally around 3 feet, and roughly 18 to 30 kg with a short muscular tail. They got a thin wormlike body which is proportionally much smaller relative to its biomechanical suit. Without their sophisticated lasersight system and powerful robotic hands, the Demasturbots are blind and physically weak pidaroids of xenomorph evolutionary background.

They are referenced in lots of historical texts as The Dolboebs and are known for being responsible for many of the alien abduction cases stretching from the 17th century all the way in to the 1960's. On Earth-like planets, whose native habitants have not yet developed non-vaginal ultrasex, their spaceships will still appear in order to abduct virgin creatures of the local fauna, possibly for demasturbating them and creating biosuits (their offspring are presumably implanted inside living virgins).

Demasturbots breathe 80% less oxygen, and 40000 times more green propane gas than humans, they are absolutely incapable of adapting themselves to Earth's atmosphere if deprived of a breathing apparatus.
