More details:Vision returns in Part 2, but sacrifices himself at the end to defeat Thanos. It's a team effort, but he is the one who actually delivers the killing blow.The Avengers do not get back together again until literally the final battle in Gauntlet.Iron Man - Becomes the new leader of the Avengers. Set up to be a Nick Fury type of figure in future movies.Captain America - Sacrifices himself in Gauntlet to trick Thanos into removing the aforementioned gauntlet. Winter Soldier is set up to become the next Cap, but he doesn't actually do it in these films.Thor - Returns to Asgard to rebuild and rule. Probably not returning to the franchise after this.Hulk - His three-film arc begun in Ragnarok ends & he just kind of hangs around. He ends his romance with Black Widow. Doesn't feel like his character has been fully wrapped up, so I'd bet he's coming back.Hawkeye - Killed by Thanos in Gauntlet while protecting his family.Black Widow - Survives, but her story is basically finished. Hawkeye's death inspires her to commit fully to being a hero. Probably not coming back.Spider-Man, Black Panther, Doctor Strange, Captain Marvel, Scarlet Witch, and the Guardians (apart from Gamora) all survive and will be developed in future films.Gamora is killed by Thanos in War & her death is used to demonstrate that he means business. It's very abrupt and unexpected.There's a fake-out in the second movie when War Machine's suit malfunctions and they make you think he's dead, but Tony saves him. He's still a cripple at the end & he explicitly says he's retiring.Ant-Man and Falcon are minor characters and they make it through unscathed. Wasp has a slightly more prominent role and will probably be an Avenger in future films, but she only appears in Gauntlet.
