Shortly before Barton was born, his father retired from the Avengers to live with his family, as with another child, Clint needed to help out a soon-to-be outnumbered Laura. They also decided to have Barton's middle name be Pietro after Pietro Maximoff, who sacrificed his life for Clint during the Battle of Sokovia.

- ―Laura Barton to Nathaniel Barton
In 2018, Barton's family was having a picnic on their homestead, during which he played catch with his brother, Cooper. Cooper and Laura praised Barton's developing throwing skills. Laura asked Barton if he wanted mayonnaise or mustard on his hot dog, but Barton asked for ketchup instead. Suddenly, he became one of the trillions killed by Thanos' Snap, alongside his mother, brother, and sister.
Five years later in 2023, Barton was resurrected, along with the rest of his family, by Hulk. Shortly afterwards, Barton, Cooper, Lila, and Laura were all reunited with Clint, who had not seen them for five years, which were only hours for them.
