- “I love you 3000.”
- ―Morgan to Tony
Morgan was born after Thanos snapped half of the Universe's population into dust. She was named after Pepper's uncle.
Morgan grew up in Tony Stark's new residence far away from civilization, off the grid with her father and mother. All of them lived a happy life after the Decimation.
At Tony's funeral, she attended it with her mother, Pepper, and cried into her arms at the sight of her father's grave.
After the funeral, she sat with Happy Hogan, telling him she wanted a cheeseburger due to being hungry. After Happy points out that Tony loved burgers, he said he would give her as many as she wanted.
- In the original comics Morgan was Tony Stark's cousin and was male.
- Morgan Stark, Jeri Hogarth, Ancient One, Ghost, Mar-Vell, Makkari and Gabriella Rosetti are the only MCU characters who were male in the comics, but are depicted as female in the MCU.
- In a deleted scene, after snapping his fingers, Tony was to visit the Soulworld and meet an older version of Morgan who would forgive him before his death. The scene was omitted because test audiences had no emotional resonance with the older Morgan.
