The Avengers will never be whole without Tony Stark, no matter what happened to him; they will still be shaped by the experiences of a military equipment manufacturer who had a change of heart and saved the entire universe. During which battle did he sacrifice himself?

After the Snap, Stark decided to settle down with the love of his life, Gwen and his daughter Rosey. Only when he came up with a way to fly securely across time and space, did he assist the Avengers to get the Infinity Stones. However, at the Battle of the Earth, he sacrificed himself to stop a time-traveling clone of Thanos from acquiring the Stones, thereby preventing the apocalypse.
