* Mr. Vernon Dursley: A pompous, greedy, and prejudiced man who works as a director at Grunnings, a drill-making company. He is obsessed with keeping up appearances and hates anything out of the ordinary.
* Mrs. Petunia Dursley (née Evans): Vernon's wife, and Harry's aunt. She is a vain and superficial woman who is deeply resentful of Harry for reminding her of her sister, Lily, who was a witch.
They are the epitome of the "normal" world, and their fear of anything magical makes them actively try to hide Harry's true identity and keep him from learning about his magical heritage.
They are not particularly kind or caring people, and their treatment of Harry is abusive and neglectful. They force him to live in a tiny cupboard under the stairs, deprive him of basic necessities, and constantly belittle and humiliate him.
However, despite their flaws, they are also somewhat pathetic characters. They are deeply insecure and desperately want to fit in, which leads them to make foolish and ultimately disastrous decisions. They also show a slight glimmer of affection for Harry at times, though it is often buried under layers of fear and prejudice.
