Which 2018 Marvel Cinematic Universe film sees the villain Thanos successfully collect all six Infinity Stones and, with a snap of his fingers, wipe out half of all life in the universe?

The 2018 Marvel Cinematic Universe film that culminates in the villain Thanos successfully gathering all six Infinity Stones and, with a single snap of his fingers, eradicating half of all life in the universe is *Avengers: Infinity War (Review)*. This pivotal movie marked a shocking turning point in the MCU, as the seemingly invincible heroes failed to stop the Mad Titan from achieving his catastrophic goal. The "snap," as it became known, instantly wiped out countless beings across the cosmos, including many beloved characters, leaving the surviving heroes and the universe in a state of profound loss and despair.

The six Infinity Stones—Space, Mind, Reality, Power, Time, and Soul—are ancient and immensely powerful artifacts, each embodying a fundamental aspect of existence. They were formed from six singularities that predated the Big Bang and were compressed into concentrated gems by cosmic entities. Individually, each stone grants its wielder incredible abilities related to its specific domain. However, when brought together and wielded through a conduit like the Infinity Gauntlet, their combined power allows for absolute control over all of reality.

Thanos's grim quest to collect these stones was driven by a twisted philosophy. He genuinely believed that the universe was suffering from overpopulation and a finite amount of resources, leading to inevitable collapse, a fate he claimed befell his own home planet, Titan. His solution was to randomly eliminate half of all living creatures, which he saw not as genocide, but as a merciful act to restore balance and ensure the survival and prosperity of the remaining life. *Avengers: Infinity War* was the culmination of a decade of interconnected storytelling within the MCU, building towards this epic confrontation and Thanos's ultimate, devastating victory.
