The displacer beast always struck me as an odd monster. I suppose I should have realized it had a sci-fi origin:
The displacer beast was inspired by the coeurl, a feline-like creature from the 1939 science fiction story "Black Destroyer" by A. E. van Vogt[1], later incorporated into the novel The Voyage of the Space Beagle (1950).
More on the coeurl: Coeurl is a fictional alien race of predators created by the late science fiction novelist A. E. van Vogt (1912-2000) and featured in his first published short story "Black Destroyer" (1939), later incorporated in the novel The Voyage of the Space Beagle (1950). Its resemblance is comparable to a large cat, except that its forelegs are twice as long as its hind legs, and it possesses tentacles (most likely two) attached to its shoulders. These tentacles terminate in suction cups. Its skin coloration is not mentioned, but it may be inferred from the title of the story that it is black. It sustains itself by feeding upon a substance it calls the Id of other beings, which is not related to the Freudian concept but is actually organic phosphorus, most probably as the phosphate groups bound in ATP.
Now where do blink dogs come from?
