Avengers

The Avengers were a team of enhanced individuals formed to ensure international security. They were headquartered at the Avengers Compound in New York City until it was destroyed in October 2023.

S.H.I.E.L.D. director Nick Fury had conceived a plan to defend Earth through the Avengers Initiative following the end of the Kree–Skrull War campaign on Earth. The Avengers was founded after the during the Chitauri invasion. In the aftermath of the Hydra uprising within S.H.I.E.L.D. in 2014, the Avengers entered into a conflict with the organization. The Avengers later moved into Stark Tower. Tony Stark, a member of the Avengers, created Ultron to defend Earth, forcing the Avengers into obsolescence. Ultron began a campaign to eliminate humans from the Earth. The Avengers fought against Ultron and inducted additional members after the Battle of Sokovia. The Avengers became a vigilante organization following its conflict with Ultron.

In 2016, Steve Rogers led an assignment to eliminate Brock Rumlow. During the mission, Wanda Maximoff misdirected a suicide bomb into an office building, killing 26 people. Following the incident, the United Nations ratified the Sokovia Accords, forcing the Avengers to become a public organization. The accords divided the Avengers into warring factions led by Stark and Rogers. The factions fought against each other in the Battle at Leipzig-Halle Airport. Stark later discovered that Bucky Barnes, an associate of Rogers who was falsely accused of perpetrating the United Nations Vienna office bombing during the ratification of the Sokovia Accords, was responsible for assassination of his parents, leading to a final battle between Stark and Rogers that ended the Avengers.

During the Infinity War, the factioned members of the Avengers fought against Thanos, though they were defeated. Thanos initiated the Snap, eliminating half of all life in the universe. Five years later, Scott Lang, a member of the Avengers, returned to Earth after being trapped within the Quantum Realm. Lang devised a plan, known as the time heist, to time travel to the past and revert the effects of the Snap. The time heist reunited the Avengers, who obtained all six Infinity Stones. Bruce Banner, a member of the Avengers, initiated the Blip. Concurrently, the Thanos of that time period time traveled and destroyed the Avengers Compound. In the resulting Battle of Earth, Thanos was defeated, though at the expense of Stark's life. The Avengers disbanded after the battle.
