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.
The Ministry of Magic could be the main antagonist. They might view Harry's fascination with Dementors as a sign of him turning to the dark side. So they try to stop him from his research and exploration of Dementors, fearing he'll use their powers for evil. After all, Dementors are associated with dark magic in the eyes of the Ministry.
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.
Common themes include power and control. As a Dementor, Harry has certain powers that he needs to learn to control. There's also the theme of acceptance. How do the other characters in the wizarding world accept or reject Harry in his new form? And of course, the theme of the battle between good and evil within himself, as Dementors are typically associated with evil, but Harry has always been on the side of good.
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.
I'm not sure specifically as I haven't read this particular fanfiction. But it might be about a unique relationship where Harry is somehow paired with the so - called 'Dementor Prince', perhaps exploring a very different kind of magical bond or adventure in the wizarding world.
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.
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.
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.
