The story of Harry Potter's Dudley Dursley goes beyond his last scene in Harry Potter and the Deathly Hallows. Dudley's parents, Vernon and Petunia Dursley, encouraged their son's mean-spirited attitude towards his cousin instead of trying to shape him into a better person. Dudley could have been like a brother to Harry, but instead he tormented him, contributing to Harry's childhood being far more miserable than it should have been.

After learning that Harry was a wizard, the dynamics between Harry and Dudley shifted significantly, especially after Rubeus Hagrid used magic to give Dudley a pig's tail. The cousins' dynamics continued to change after Dudley experienced the horror of Dementors and was saved by Harry. Their relationship was never the focus of the Harry Potter books, but it was an important part of the story that continued to develop even after Deathly Hallows' ending.
