A Naruto - Dementor fanfiction could involve Naruto learning about the Patronus charm from the Dementor - infested world. His strong will and spirit could allow him to quickly master it. He could then use his unique Naruto - style Patronus, perhaps in the shape of a fox or some other symbol related to his ninja heritage, to protect his friends and fight off the Dementors.
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.
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 would be really strange. Maybe it would involve Harry being fascinated by the Dementors' power, like their ability to suck out souls. He could be secretly observing them, trying to understand how they work, which is completely against his normal character who hates and fears them.
He might be feared by others. Since Dementors are known for their terrifying and soul - sucking abilities, people would be very cautious around Harry. His friends might even be initially scared of him until they understand he can control these powers.
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.
If Harry gets the Dementor's kiss in fanfiction, it would likely be a very dark turn of events. His soul would be sucked out, leaving his body an empty shell. This could have a huge impact on the wizarding world. His friends, like Ron and Hermione, would be devastated. They would probably be on a mission to find a way to reverse it, if possible. It could also lead to chaos as Voldemort might take advantage of Harry's absence to gain more power.
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.
In a fanfic where Harry is kissed by a Dementor, he would likely lose his soul. This is because the Dementor's kiss sucks out a person's soul. It would be a very dark turn for the story. His friends would probably be devastated and the fight against Voldemort would take a huge hit as Harry was seen as a key figure in that battle.
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 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.
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.
