Avengers: Endgame
In 2018, twenty-three days after Thanos killed half of all life in the universe, Carol Danvers rescues Tony Stark and Nebula from deep space and they reunite with the remaining Avengers—Bruce Banner, Steve Rogers, Thor, Natasha Romanoff, and James Rhodes—and Rocket on Earth. Locating Thanos on an uninhabited planet, they plan to use the Infinity Stones to reverse his actions, but discover Thanos has already destroyed them to prevent further use. Enraged, Thor decapitates Thanos.
