When the MCU began, Tony Stark was a self-centered playboy billionaire. By the time he died 15 years later, he was Iron Man — one of Earth's Mightiest Heroes.

The trio of Captain America (Chris Evans), Thor (Chris Hemsworth), and Iron Man took on Thanos (Josh Brolin). After a huge battle that enlisted the help of all of those snapped, it came down to Iron Man and Thanos. He swiped the gauntlet off of Thanos' hand and ended up snapping him and his army away. Iron Man saved the world, but it cost him his life and he died on the battlefield.

According to the MCU timeline (via GamesRadar), this occurred on October 17, 2023. Remember, the first snap occurred in 2018, and five years went by before those snapped returned.
