Muggles' Guide to Harry Potter/Characters/Amos Diggory

Overview
Amos Diggory is the father of Cedric Diggory. He is the head of the Department of Magical Transportation, in the Ministry of Magic, and he works with Arthur Weasley.

Goblet of Fire
Amos Diggory and his son, Cedric are heading to the Quidditch World Cup. Along the way, they meet up with Harry, Hermione, and the Weasley family: Ginny, Ron, Fred, George, and Mr. Weasley. Both families, travelling by the same Portkey, are searching for it. Amos makes a big noise about how his son Cedric had beaten "the famous Harry Potter" at Quidditch, while Cedric down-plays the victory. Upon reaching their destination, the Diggorys go on to different campsite.

Amos next appears, or at least his head does, in the Weasley's fireplace, when he informs Mr. Weasley that Mad-Eye has gotten into trouble. After updating Mr. Weasley, Amos accepts a slice of toast from Mrs. Weasley, then departs.

Amos appears again immediately before the Third Task. The Champions' families have been invited to the last event, and Amos and his wife are present; Amos makes some cutting remarks about Harry participating in the Tournament, but Cedric tries to quiet him.

Finally, Amos and his wife visit Harry in the Hospital Wing after the third task, and thank Harry for returning Cedric's body. When Harry tries to give them the prize money which Cedric would have won, they refuse to accept it. Despite Harry's protests, they insist he keep the entire thousand-galleon prize.

Strengths
Like his son, Cedric, Amos is, at heart, an honest and fair person. He is also devoted to his family, and dearly loves his son.

Weaknesses
Amos excessively boasts about Cedric's accomplishments, often while undermining Harry Potter, much to Cedric's embarrassment and annoyance.

Relationships with Other Characters
Amos is familiar with, and quite friendly towards, most characters and is quite close to Arthur Weasley. He is a little dismissive towards younger characters, Harry in particular, whom he sees as a rival to Cedric.

He is noticeably unfair and belittling towards Winky, shouting at her and calling her simply "elf".

Analysis
Amos Diggory almost seems a stereotype – a man reliving his youth through his child. Amos is inordinately proud that Cedric beat Harry in a Quidditch match, and of Cedric's showing in the Triwizard Tournament. He finds Cedric's victories more noteworthy than does Cedric, who seems embarrassed by his father's effusive pride when they meet Harry and the Weasleys early on in Harry Potter and the Goblet of Fire.
