<P> Barty Crouch Sr. makes his first appearance in the series at the Quidditch World Cup in Goblet of Fire . Crouch accuses Harry, Ron and Hermione of attempting to set off the Dark Mark, and when Winky is found to have Harry's wand, he angrily dismisses Winky, as the house - elf is supposed to look after his son, who is always under an Invisibility Cloak . Voldemort and his servant Peter Pettigrew show up at the Crouch family home and put Crouch Sr. under the Imperius Curse, freeing Crouch Jr from the Imperius Curse placed on him by his father and thus allowing him to rejoin Voldemort . Crouch continues to appear in public at first and is one of the five judges at the Triwizard Tournament . However, worried that Crouch will fight off the Imperius Curse, Voldemort later keeps him imprisoned within the house and has him communicate exclusively through supervised owl post . Later in the book, Crouch, who has escaped from his home, meets Harry and Viktor Krum in the Forbidden Forest and begs to see Dumbledore . However, Harry, while on his way to inform Dumbledore of the events, unwittingly alerts Crouch Jr., in the disguise of Mad - Eye Moody, to his father's presence . Crouch Jr. immediately goes to the forest, kills his own father, transfigures the body into a bone, and buries it on the Hogwarts grounds . </P> <P> Roger Lloyd - Pack appeared as Crouch in the film adaptation of Harry Potter and the Goblet of Fire . </P> <P> John Dawlish is an Auror . He is very capable and self - assured, and is described as a "tough - looking wizard" with "very short, wiry" grey hair . He leaves Hogwarts with Outstandings in all his N.E.W.T.s (Nastily Exhausting Wizarding Test). However, it is a running joke of the books that in any appearance or mention of him, he is eventually hexed, usually due to a combination of far superior opponents and sheer bad luck . </P> <P> In Harry Potter and the Order of the Phoenix, Dawlish accompanies Fudge to Hogwarts to confront Harry about the secret Dumbledore's Army meetings . Dawlish is knocked out along with Fudge, Umbridge, and Kingsley when Dumbledore, who put the blame for the Army on himself, escapes . A few weeks later, Dawlish is among the wizards who attempt to arrest Rubeus Hagrid when Umbridge sacks the gamekeeper .

Dawlish appears again in Half - Blood Prince guarding Hogwarts after the commencement of the Second War . He is sent to follow Dumbledore when the Headmaster leaves school to search for Voldemort's Horcruxes, but is "regretfully" hexed by the Headmaster . He is Confunded by an Order member early on in Harry Potter and the Deathly Hallows, and gives Death Eater Corban Yaxley false information on Harry's removal from the Dursleys' home . Being Confunded, he is defeated by Dirk Cresswell, who escapes halfway on the way to Azkaban . Later, Dawlish is sent to arrest Augusta Longbottom . After a struggle, her defence places Dawlish in St Mungo's Hospital . </P>
