alien invasion
Spacecraft assault scenario
Alien invasion is a scenario in which extraterrestrial beings arrive on Earth with hostile intent—to conquer, colonize, or exterminate humanity.
The concept dominates science fiction: alien invasion movies, alien invasion novels.
It serves as allegory for fears of the foreign or unknown.
Sometimes used loosely for any overwhelming incursion: an alien invasion of jellyfish in the harbor.
