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.
Perhaps in this fanfiction, Harry becomes the 'King of Dementor' by making a pact with them. This pact might give him access to their powers and knowledge. He could then use this to change the balance of power in the wizarding world. For example, he could use Dementor - based magic to defeat Voldemort in a completely different way than in the original books.
In the 'Harry Potter King of Dementor' fanfiction, it might be that Harry is the only one who can truly understand Dementors. He discovers that they are not just mindless, evil creatures. He becomes their king by showing them a new way of existence. This could lead to a whole new world order in the wizarding community where Dementors are no longer just feared, but are an integral part of a new magical society.
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.
One possible plot is that Harry absorbs the dementor in a moment of extreme danger. This changes him in some ways. His Patronus might become more powerful as a result. He may also start to understand the dementors' origin and find a way to stop their creation. He could then share this knowledge with the wizarding world.
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.
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.
The story could start with Harry having a near - death experience where a Dementor's kiss was almost upon him. Instead of being terrified, he becomes oddly fascinated. He begins to research their origin, their connection to Azkaban, and their role in the wizarding world. As he does this, he discovers some ancient magic related to Dementors that no one else knew. This knowledge could either lead him down a dark path or help him to change the way Dementors are perceived in the wizarding community.
Yes, it's possible in fanfiction. It could be justified as self - defense. If a dementor was about to attack an innocent, especially someone Harry cared about, he might be pushed to use a powerful spell to kill it rather than just the Patronus charm which usually just drives them away.
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.
Well, it could be about Harry Potter somehow becoming the king in the North. Maybe he uses his magic in a new way to gain this position, ruling over a magical kingdom there.
It could be about Harry Potter achieving a supreme status, like a 'king of kings'. Maybe he unites the wizarding world in a way no one has before, bringing peace and new magical laws.
One possible plot could be that Harry, as the 'King of Hogwarts', uses his new - found status to reform the school's rules. He could make the houses work together more closely, perhaps by creating new inter - house competitions that focus on cooperation rather than competition. For example, a magical scavenger hunt where students from all houses must team up to find hidden magical artifacts around Hogwarts and its grounds.
