The Dementors joined the Dark Lord after. When a Dementor sucked the soul out of Barty Crouch Jr., that was before the Dementors joined the Dark Lord. They only joined him after his return. When he returned to a body, he said the Dementors ‘will join’ him and the Death Eaters, indicating they hadn’t already joined them before. “The Dementors will join ...

Dementors are described in the books several times as gliding. For example, from the attack on Dudley and Harry in The Order of the Phoenix: A towering hooded figure was gliding smoothly towards him, hovering over the ground, no feet or face visible beneath its robes, sucking on the night as it came Of course, gliding does not quite equate to ...

As usual, it's hard to prove a negative. However, the time I remember seeing dementors flying in the films was during the Quidditch match in Prisoner of Azkaban. If I look up the passage in the book, the dementors are on the ground and not flying. Before he'd had time to think, Harry had taken his eyes off the Snitch and looked down. At least a ...

In addition to the more philosophical points raised by others, there is hard evidence that Harry's boggart remains a dementor after Lupin's lessons in Goblet of Fire. When Harry is in the maze he encounters a boggart and it takes the form of a dementor: Then, as he turned a corner, he saw... a dementor gliding toward him. Twelve feet tall, its face ...

Yes, they can. In Book 5, stray Dementors attempted to kiss not only Harry, but Dudley Dursley as well. From Chapter 1, Dudley Demented He had run barely a dozen steps when he reached them: Dudley was curled on the ground, his arms clamped over his face; a second dementor was crouching low over him, gripping his wrists in its slimy hands, prizing them ...

Not exactly an answer to what he heard, but here it goes anyway: As far as I remember it's never mentioned again in the books. I did find this, but not sure how credible it is And here's the quote: "People usually ask me, what is it that Dudley saw during the Dementor attack?" Rowling said. "My feeling is that he saw himself, exactly for what he ...

Dementors do not breed (No, there'll be no sweet sweet love in Azkaban tonight!) but rather grow like fungi under certain conditions. They multiply by feeding off human despair, unhappiness, hopelessness, and are akin to depression. They are pretty insidious creatures. Dementors have no soul themselves, thus their constant drive to suck the souls from others....

Dementors are under the control of the Ministry of Magic, at least for the duration of all seven Harry Potter books. During Harry's hearing for violating the Decree for the Restriction of Underage Wizardry in Order of the Phoenix, Dumbledore discusses this with Umbridge, and Fudge confirms Dementors are under Ministry control: ‘If it is true that the ...

They can likely communicate since they told the Ministry what Sirius was muttering prior to escaping from Azkaban. "Molly, how many times do I have to tell you? They didn't report it in the press because Fudge wanted it kept quiet, but Fudge went out to Azkaban the night Black escaped. The guards told Fudge that Black's been talking in his sleep for a ...


28

There are certain defences that are known (canonically) to work against dementors. We can dismiss the most obvious; The Patronus charm is certainly the method with which Harry is most familiar. This isn't especially surprising since his teacher was arguably the "go-to guy" when it came to teaching the patronus charm and massively in favour of them over ...


26

I interpret what JK Rowling has said to mean that however many Dementors already exist cannot be destroyed by any means, Wizarding or human, meaning there is no spell, potion, curse, etc, that will eradicate them. I expect there is the possibility that Dementors eventually die a natural death. I suspect that the number of Dementors in the world ebbs and ...


26

In a word, no. The patronus must take the form of something that creates positive feelings (a dementor is by definition the embodiment of unhappy feelings, primarily fear) and the shape of an animal with whom they share an affinity. Not only would someone who had an affinity for a dementor be unable to create a patronus, it's also fairly questionable whether ...


24

Dementors are probably of human intelligence People generally treat Dementors as if they were capable of formulating complex thoughts. For example, when the Dementors search the Hogwarts express, Lupin has this to say: "And Professor Lupin stepped over you, and walked toward the dementor, and pulled out his wand," said Hermione, "and he said, 'None of ...


23

I'm going to go with yes. First, evidence that the soul would be (effectively) destroyed comes from Lupin's quote: your soul is gone for ever ... lost Now, the question is whether the dementors could suck the foreign soul out: they clamp their jaws upon the mouth of the victim and – and suck out his soul Now, I'm going to go (a bit) out on a limb ...


23

I don’t know a canon answer, but I can come up with some plausible explanations: Casting a Patronus was probably impossible for Sirius. Remember that he’s spent the last twelve-or-so years in Azkaban, without a wand, and without casting spells with wands. The Patronus (even a wispy one) is a fairly advanced piece of magic, and Sirius would probably need a ...


22

this is a great question, I have two possible explanations: Snape had seen the Dementors and on Dumbledore's orders had not told Fudge the truth AND/OR the Dementors do not have any sense of Loyalty to the Ministry and as Hagrid says, they do not care about innocence, so telling Fudge that they were going to perform the Kiss would not have stirred any ...


22

Well, the first thing to notice is that, at this point, Harry has a lot more experience with battling Dementors than Hermione, because of his practice sessions with Lupin. True, he'd been taking on a boggart (and only one), but Hermione has only ever encountered the Dementor on the train and that one wasn't especially hostile. Harry, however, has built up a ...


19

The answer is in the details of the quote. You cannot destroy Dementors There is a great deal of difference between being able to destroy a Dementor, and them never dying. This leads into speculative theory, but I believe the idea is that by limiting the conditions in which they thrive, you can starve the dementors, and cause their numbers to diminish....

They may have benefited from their victims being together. Both the Ministry of Magic and the Dark Lord stationed the Dementors at Azkaban, where the prisoners were all held captive and grouped together in one building. They couldn’t use magic, and they were unable to escape the Dementors or fight back. The atmosphere of Azkaban was beneficial to the ...


18

I don't know that it's directly stated, but it's implied that they are immune to most physical force, possibly only being partially corporeal themselves. In The Prisoner of Azkaban, Remus Lupin states that there are ways to fight them, (the implication being that there are few ways... and those are not simple, or for some other reason hard to use.) “...


18

Here's a theory that, as far as I know, is fully possible within canon, if creepy and disorienting: We already know from Harry's experience with Dementors that they can cause you to relive your worst memories - in Harry's case, it was to the point where he was actually hearing his mother's voice. If this is an ability that can be controlled consciously, ...


18

No. There were no Dementors in Nurmengard. It should be noted that the Dementors only resided in Azkaban because it was a natural breeding ground, even before the site became used as a prison. Those who entered to investigate refused afterwards to talk of what they had found inside, but the least frightening part of it was that the place was infested ...


17

According to the Azkaban entry on Pottermore, Kingsley gets rid of the Dementors and replaces them with Auror guards: Under Kingsley Shacklebolt, Azkaban was purged of Dementors. While it remains in use as a prison, the guards are now Aurors, who are regularly rotated from the mainland. There has been no breakout since this new system was introduced. We ...


17

Voldemort believed that the Dementors were natural allies of the Death Eaters; I would suggest this demonstrates one of Voldemort's inherent weaknesses: The overestimation of his power (against people, creatures, etc). Voldemort believes the Dementors are loyal to him, but I'd be willing to bet that Voldemort in turn garnered absolutely no loyalty toward the ...


16

Death Eaters have no need of Patronus charms. From this interview with JK Rowling: Samantha: Was snape the only death eater who could produce a full patronus J.K. Rowling: Yes, because a Patronus is used against things that the Death Eaters generally generate, or fight alongside. They would not need Patronuses. Quote to support the above assertion, ...


15

Possibly not. JK Rowling’s website says this of Squibs: Arabella Figg never saw the Dementors that attacked Harry and Dudley, but she had enough magical knowledge to identify correctly the sensations they created in the alleyway. This has widely been accepted to mean that it would be impossible for her to see a Dementor. We know that Muggles can’t see ...


14

The scene plays out differently in the book and the film Book The dementor doesn't attack him personally. It stands near him and Harry is simply affected more than his peers. Standing in the doorway, illuminated by the shivering flames in Lupin’s hand, was a cloaked figure that towered to the ceiling. Its face was completely hidden beneath its hood. ...


14

They both spread death, darkness, destruction, dread, and despair. The Death Eaters allow the Dementors to take people's souls - the Ministry doesn't. They're both... evil ;) The Dementors feed off of despair. Voldemort's army spreads it, allowing the dementors to breed. The Dementors take care of the Death Eaters enemies, taking their souls, and ...


13

There is no quote directly stating it one way or another but there is some evidence both for and against. For Dementors "live" on the island of Azkaban. Although the island is nearish to the coast, Sirius manages to swim the distance, I doubt the Dementors swim there. Maybe they get taken their by ministry boat or side-along apparition (I wouldn't want to ...


12

I'd say yes, the dementors did affect the Death Eaters in Azkaban. First of all, during these times, the dementors were working for the ministry. In exchange, they were allowed to "suck happiness" from the prisoners. During these times, there really was no reason for a dementor to help a death eater at all: sure, they used to be allies, but that was long ...
