Hopkinsville Goblin

The Hopkinsville Goblins are a reported real-world alien species and cryptid from the controversial Kelly-Hopkinsville Encounter of 1955, which has gone down in history as one of the most violent and prolonged conflicts between Humans and supposedly extraterrestrial beings.

Biology
The Hopkinsville Goblins were reported to be small humanoids with goblin-like appearances, hence the nickname given to them.

Abilities
The Hopkinsville Goblins were said to exhibit many superhuman abilities and seemed to "swarm" the area, frightening the residents - traits such as resilience, levitation and rapid speed seemed to be implied, along with the usual UFO-related phenomena suggestive of advanced space-travel.
