Well, in some fanfictions, Harry might use a super - powered Patronus. His Patronus could be stronger than usual, perhaps due to some newfound magic or a special connection he has developed. It could be so powerful that it simply overpowers the dementors and destroys them.
It's often described as an icy - cold and terrifying experience. The Dementors are usually depicted as hovering over the female Harry Potter character, their hooded forms menacing. The Kiss itself might be described as a sort of draining sensation, like all the warmth and hope being sucked out of her.
In many fanfictions, Dementors are used as a tool to create a sense of despair. For example, when a character is facing a Dementor, their worst memories are brought to the surface, and this can be used to develop the character further. The fanfictions might also show how different characters react to the Dementors in different ways. Some might be paralyzed with fear, while others might try to fight back using magic like the Patronus charm.
One possibility is that Harry would grow up to be a very different person. Dementors are creatures of despair, so he might be more withdrawn and less trusting. He could also have some very dark powers, having been exposed to the dementors' influence for so long.
It could be really wild. Maybe Harry uses his Patronus charm in a new and unexpected way. Instead of just driving the dementors away, he somehow makes the Patronus 'entertain' the dementors. Like the Patronus could be a stag that does acrobatic jumps and the dementors are curiously watching it, almost like they are being played with.
In fanfiction, dementors often serve as a source of great danger. For example, in many stories, they are used by dark wizards to guard important or secret places. Their ability to suck out the soul makes them a terrifying obstacle for the heroes to overcome.
In fem Harry Potter fanfiction, the Dementors' Kiss can be a really dark and powerful element. It often represents ultimate despair and loss of the soul. It can be used to heighten the stakes for the female Harry Potter character, showing just how dangerous the magical world she lives in can be.
If Harry killed dementors in a fanfiction, it could have several implications. For one, it could be a sign of his growth and mastery of magic beyond what was shown in the books. It might also lead to a different relationship between him and the Ministry of Magic. Since dementors were used as guards in Azkaban, their deaths could cause chaos in the prison system. Additionally, it could change the perception of the dark side in the wizarding world, as dementors are a symbol of the darkest elements.
They could be portrayed as having a bit of good in them. For example, they might be under some sort of dark spell that forces them to act as they do, and if that spell is broken, they could be more like guardians of the wizarding world in a different way.
Well, if Harry Potter were kissed by dementors in fanfiction, it'd be a really dark plot twist. First off, the act of the Dementor's Kiss sucks out the soul. So Harry would be left as an empty shell. The wizarding world would be in chaos. His friends like Ron and Hermione would surely go on a desperate quest to somehow reverse the situation, perhaps seeking powerful magic that had been long forgotten.
