One great 'Harry Potter Dementor King Fanfiction' could be 'The Dementor's Reign'. It explores a world where the Dementor King has a more prominent role in the wizarding world. It's full of interesting plot twists and new takes on the magical lore of Harry Potter.
I also like 'The Legend of the Dementor King'. This fanfiction weaves a tale around the origin of the Dementor King. It shows how his existence might have influenced the history of Hogwarts and the wizarding world at large. The author does a great job of building a new narrative within the existing Harry Potter universe.
Well, it could be about a Harry Potter who has some special power over Dementors. Maybe he can control them instead of just fending them off with a Patronus. He could use this new - found power to his advantage in the wizarding world, like using Dementors to guard against dark wizards.
Another theme is the nature of darkness. Since Dementors are associated with darkness, fanfics often explore how the Dementor King embodies this darkness and how it affects the characters around him. They might look at how the characters struggle against this all - consuming darkness. For example, a character might have to find their inner light to resist the Dementor King's influence. It can also involve themes of redemption, as some stories may have the Dementor King or those influenced by him seeking redemption from their dark deeds. This adds a layer of complexity to the characters and the overall story.
Maybe it's a rogue group of wizards who fear Harry's power over Dementors. They might think that Harry is going to use the Dementors to take over the wizarding world in an unjust way. So they band together to try and stop Harry before he can fully embrace his role as the King of Dementors.
Yes, there are some interesting 'Harry is a Dementor' fanfictions out there. Some explore the unique concept of Harry being a Dementor in a creative way, like how it changes his relationships with other characters. For example, his interactions with Hermione and Ron might become more complex as he now has this dark and somewhat feared nature.
It's not a very common or popular concept. Harry Potter is typically seen as a hero opposed to Dementors, which are dark and terrifying creatures. Fanfiction usually focuses on more positive or heroic aspects of Harry's character rather than making him a fan of Dementors.
It would be really dark and mysterious. Harry as a Dementor Animagus would have some very different powers and abilities. He might be able to control the Dementors in a way, or use their fear - inducing abilities for his own purposes, perhaps in the fight against Voldemort. But it would also be a struggle for him to control his Dementor side, as Dementors are associated with negative emotions.
It could be due to a blood - magic related incident. Suppose there is some long - lost connection between Harry's family and the origin of Dementors. A spell or a ritual that awakens this connection might endow Harry with Dementor - like powers. For example, if there was an ancestor who was involved in the creation of Dementors in some way, and that knowledge or power was passed down in a latent form in Harry's blood.
Well, in certain fanfictions, the Dementor's Kiss is often explored in relation to a character's hidden past or secrets. Maybe a character who was supposed to receive the Kiss actually has a dark past that the Dementors are drawn to, but this also gives them a strange power to resist it. It can also be used as a way to explore the nature of the soul in the Harry Potter universe more deeply.
One possible plot could be that Harry's mother was secretly researching dementors for some noble reason, like finding a way to cure their 'evil' nature. She might be collecting information about them, which could put her in danger as dementors are not to be trifled with. This could then lead to a series of events where her knowledge is passed on to Harry in some way, and he has to continue her work.
In a fanfiction where Harry Potter kills a dementor, it could lead to many consequences. First, the wizarding world might react with shock as dementors are usually just sent back to Azkaban. It could also change Harry's perception of himself as a wizard, as taking a life is a huge deal. Maybe he would face some sort of backlash from the Ministry of Magic for acting outside the normal procedures of dealing with dementors.
