Quick Answer
Thanos is an alien warlord from the doomed planet Titan who seeks to use the Infinity Stones to eradicate half of all life in order to curb overpopulation and prevent the universe’s eventual collapse.
Explanation
Thanos, portrayed by Josh Brolin in the Marvel Cinematic Universe, originates from the planet Titan, which is described as doomed. He views the universe’s continued growth as unsustainable and believes that eliminating half of all life will stabilize overpopulation. To achieve this goal, Thanos pursues the six Infinity Stones, which grant immense power. With the aid of his adopted children, he battles the Avengers, the Guardians of the Galaxy, and their allies in the Infinity War. After successfully assembling the Stones, he snaps his fingers, causing the Decimation—a mass disintegration that wipes out half of all life in the universe.
