Tony Stark's Funeral
- "This time travel thing we're gonna try and pull off tomorrow, it's got me scratching my head about the survivability of it all. Then again that's the hero gig. Part of the journey is the end. What am I even tripping for? Everything's gonna work out exactly the way it's supposed to. I love you 3000."
- ―Tony Stark
During the Battle of Earth, Tony Stark heroically sacrificed himself in order to defeat Thanos. At his funeral in 2023, Morgan watched a recording that her father had made in the event of his death, telling her that he loved her. Exiting the Stark Residence, Morgan witnessed the funeral for her father, crying into her mother's arm.
After the service, Morgan sat with Happy Hogan, where she asked for a cheeseburger, as she felt hungry. Happy comforted her, telling Morgan that her father had liked cheeseburgers as well, recalling when he returned to the United States in 2009 from Afghanistan after being kidnapped, and that he will get her as many cheeseburgers as she wanted.

Behind the Scenes
- Katherine Langford portrayed an older version of Morgan Stark in a deleted scene in Avengers: Endgame in which Tony Stark meets her in the Soulworld. The scene was shown in a test screening of the movie and both confused the audience and did not emotionally resonate with them and it was cut for these reasons.
