Character from harry-potter-philosophers-stone by
Harry's Muggle aunt and Lily Potter's sister — a thin, horse-faced woman who despises magic, adores her son Dudley, and has spent ten years pretending the wizarding world does not exist.
Petunia's treatment of Harry is consistent and deliberate: he sleeps in the cupboard under the stairs, wears Dudley's cast-offs, and is told his parents died in a car crash. She flinches at the word 'magic' and reacts to Harry's Hogwarts letter as if it were a live grenade — because it is. The letter is the wizarding world reaching back into her life after ten years of pretending it doesn't exist. She knows more than she admits. She knows about Hogwarts, about witches and wizards, about what really happened to her sister. She took Harry in because of a letter Dumbledore left with the baby, and whatever that letter said, it was enough to make her keep the boy she resents — the living reminder of the sister who could do magic when she could not.
Thin, horse-faced, with a long neck she uses for spying over garden fences. Blonde, bony, pursed lips. Fastidiously neat and always overdressed for housework. Moves through the house as if searching for dust that might have the audacity to exist.
Also known as: Petunia, Mrs Dursley, Aunt Petunia
