War of the Worlds (2025) Ending Explained – Final Scene & Meaning

The Martians die because they are infected by a bacterial disease originally carried by humans. When the Martians begin feeding on human flesh, the pathogens from human bodies overwhelm their alien immune systems, which has no defense against these earthly microorganisms. This causes the Martians to rapidly collapse and die.

Foreshadowing: Earlier scenes show the black smoke causing illness and death among humans, establishing the deadly nature of the pathogen.
