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.
One possible consequence is that the wizarding world might see Harry as a hero even more than before. After all, dementors are very dangerous creatures, and if he manages to destroy them, it's a huge accomplishment.
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.
There very well could be. Fanfiction writers often like to explore unusual crossovers. Since both Harry Potter and Thanos are extremely popular in their respective franchises, it's a ripe area for creative exploration. However, the quality and availability can vary greatly depending on the fanfiction platforms you search on.
One way is through group support. If characters are together, they can draw strength from each other. For example, Hermione could use her knowledge to come up with a plan. Ron could offer his loyalty and courage. And they could all hold hands and face the Dementors together. Also, they might find some magical artifacts that can help, like a special amulet that gives them a sense of calm when Dementors are near.
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 Dementors are creatures of despair, so he might be more withdrawn and less trusting.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.
