A few hiccups and time travel hijinks aside, the Avengers are successful in their mission to gather the Infinity Stones from the past. Tony then creates a gauntlet using the same nano-tech armor as his Iron Man suits and it's decided that Hulk, the strongest and (given the state of Thor) most sensible of the Avengers, will attempt the snap. He puts on the the gauntlet and, at first, it appears too powerful even for him to control, but eventually, Hulk manages to bring together his fingers and snaps, wishing for all those who disappeared five years ago to reappear in the present. It works, and the first sign of their success is Hawkeye receiving a phone call from his wife just moments after Hulk's snap.

6. Characters Stay Dead

Though Hulk's snap is successful in Avengers: Endgame, he isn't able to bring everyone back. (For his part, Hulk receives only some mild scarring on his arm and the right side of his body.) The Infinity Stones are powerful but they are are also specific, and Hulk is only able to bring back those who turned to dust thanks to Thanos' original snap. He even tells Clint that he really tried using all that power to bring back Natasha, but it just doesn't work. Along with Black Widow, the other characters who died in Infinity War before the snap - Loki, Heimdall, Gamora, and Vision - all stay dead.
