Dudley Dursley

Dudley Dursley is Harry Potter's cousin, and Vernon and Petunia Dursley's son. He bullies others to the point of exhaustion, and is very fat. Rubeus Hagrid, upon being angered by Dudley's father and disgusted by the Dursleys in general, uses magic to make a pig tail sprout from Dudley's fat bottom, which causes immense pain. (In the film, Dudley was eating the birthday cake given to Harry, further disgusting Hagrid and making his backside an easier target) In the summer of the second novel, Dudley is described as even more massive, so much so that his bottom droops over each side of the chair (The tail had been removed at a private hospital). He has lost none of his bullying efforts, and taunts Harry about getting nothing for his birthday. In the third novel's summer, he is even more fat, and now does not even walk between the living room and the kitchen, as his father has installed a new TV in the kitchen, at which Dudley sits all day, eating constantly. He now has five chins. Then, the summer of 1994, he is described as having "reached the size and weight of a young killer whale", and has disgusted the staff and students of Smeltings so much that the school nurse forces a diet regime upon Dudley, saying that he was now too fat for the school uniforms. Fred and George Weasley, when picking Harry up from the Dursley's house, get revenge on Dudley for bullying Harry by dropping a sweet that Dudley quickly devours, and it causes his tongue to expand greatly and cause him immense pain before it is shrunk. While still not following the diet, Dudley takes up boxing, which does not change his figure but gives him even more prominence over other children. (It is unknown what Smelting's response was to the even greater amount of bullying, and the unchanged vastness of Dudley's stomach) Dudley does not figure prominently in the story of Harry Potter; he is mainly an antagonising force to Harry during the summers. His most prominent roles in Harry's story occured during the summers of 1991, when Harry first learned he was a wizard, and in 1995, when he and Harry were attacked by Dementors on Privet Drive.

In Harry Potter and the Half-Blood Prince, the Dursleys are visited by Albus Dumbledore, who is disgusted at Dudley and blames Vernon and Petunia for their "appalling damage" on him and how he has turned out.

In Harry Potter and the Deathly Hallows, Dudley is the only member of the Dursley family to accept Harry: he shakes his hand and thanks him for saving him from the dementors. The wizards that are taking the Dursleys into hiding are not satisfied by this, and think that a more adequate apology is in order, but the Dursleys leave with no more to say.

After taking up his workout regime, Dudley became weightlifting champion at his school.
