alien invader
Hostile outer-space visitor
An alien invader is a creature from another world that arrives with hostile intent—the stuff of science fiction films and novels: The alien invaders emerged from their spacecraft.
The term also describes non-native species that aggressively colonize new ecosystems, displacing indigenous plants and animals: Kudzu is an alien invader choking out native vegetation across the American South.
