the resulting entity was driven insane. The film ended with Falcon, War Machine, Vision and Scarlet Witch joining the team after Iron Man, Hawkeye, Thor and Hulk left to explore personal issues (Quicksilver also joined briefly as was killed in the battle with Ultron). The team also was featured in the film Captain America: Civil War, which saw Captain America and Iron Man acting as leaders to two opposing Avenger teams acting against and for the 'Sokovia Accords'. The Accords would bring heroes under government control, with Captain America leading the team of Winter Soldier, Falcon, Scarlet Witch, Hawkeye and Ant-Man against the idea of being under external authority, while Iron Man and his team of War Machine, Black Widow, Vision, Black Panther and Spider-Man fight to make the heroes accountable. A third Avengers film titled Avengers: Infinity War was released on April 27, 2018, where the heroes from Civil War– now including Thor and Hulk but absent Hawkeye and Ant-Man– join forces with the Guardians of the Galaxy and Doctor Strange to stop the mad titan Thanos as he attempts to claim the Infinity Stones. Despite their efforts, Thanos manages to gather the six stones, killing Gamora and the Vision in the process, with the Snap killing Spider-Man, Doctor Strange, Star-Lord, Mantis, Drax, Groot, Black Panther, Falcon, the Winter Soldier, and the Scarlet Witch, among others. A fourth film titled Avengers: Endgame was released on April 26, 2019, which opens with the revelation that Thanos had destroyed the Infinity Stones in the present. Five years later, the return of Scott Lang (who had been trapped in the Quantum Realm after the Snap) gave the Avengers the opportunity to undo Thanos' victory via a complex scheme involving time travel; as Thanos had destroyed the Infinity Stones in the present, the team go back and gather past versions of the Stones and bring them into the present to create a new Gauntlet. After Black Widow sacrificed herself to claim the Soul Stone, a past version of Thanos travelled into the future with the goal of using the gauntlet to completely remake the universe. The final battle against Thanos featured an Avengers roster including Iron Man, Captain America, Thor, Hulk, Hawkeye, Scarlet Witch, War Machine, Falcon, Spider-Man, Captain Marvel, Ant-Man, Wasp, Doctor Strange, Rescue, Black Panther, Okoye, Bucky, Nebula, and Rocket Raccoon, as well as the Guardians of the Galaxy.
