It could be really interesting. Maybe Naruto somehow encounters Dementors in a strange crossover world. He might initially be confused by their ability to drain happiness but then use his ninja skills to fight back. For example, he could use his shadow clone jutsu to distract the Dementors while he figures out a way to deal with their soul - sucking power.
One common theme is the clash of two different universes. The Naruto universe is all about ninjas, chakra, and village politics, while the dementors come from a world of magic and fear. So there's often a theme of how these two very different elements interact.
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.
Well, one popular 'naruto dementor fanfic' might be 'Naruto and the Dementor's Encounter'. It's interesting as it combines the Naruto universe with the spooky dementors from Harry Potter. In this fic, Naruto has to face the soul - sucking dementors which makes for a really unique and action - packed 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.
One possible plot could be Hermione using her intelligence to find a way to repel Dementors without using a Patronus. Maybe she discovers some ancient magic or potion that can keep Dementors at bay. Another plot could involve a Dementor being somehow controlled by a dark wizard to specifically target Hermione, and she has to outwit both the Dementor and the wizard. There could also be a story where Hermione befriends a Dementor in a very strange turn of events, perhaps by understanding its true nature and finding a way to communicate with it, which would be a very unique take on the relationship between a character and a Dementor in fanfiction.
The plot twists can make it interesting. Imagine a 'Supernatural Good Dementor' fanfiction where the Dementor is initially thought to be good but is actually being controlled by an even greater evil. Or perhaps the Dementor has some hidden knowledge about the Supernatural world that the main characters need to figure out. The way the story unfolds, with unexpected turns and revelations, can keep readers hooked. Additionally, the relationships between the characters in the Supernatural series and the Dementor can be explored in many ways. Whether it's a friendship, a mentor - mentee relationship, or even a romantic interest, these different relationship dynamics can create a very engaging fanfiction.
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.
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.
