Well, it would be a really dark take. Harry would probably be constantly in a state of near - despair. Since Dementors are soul - sucking creatures, he might have a hard time forming normal relationships. His view of the wizarding world would be very different from the original story. He might see it as a place full of threats and darkness rather than a place with some good in it. And his Patronus, if he could even produce one, would be very weak or have an unusual form.
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 Dementors are creatures of despair, so he might be more withdrawn and less trusting.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.
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.
The original plot has Harry growing up with the Dursleys, which is bad but not as extreme as with Dementors. In the fanfic, his entire outlook on life would be different. He may not have the same sense of justice and heroism as in the original. His friends might not be the same either, as he would be a very different person. His relationship with Dumbledore would also change, as Dumbledore might not be able to reach him as easily.
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.
If Harry Potter was raised by a Creepypasta fanfic, his upbringing would be far from the typical Hogwarts - bound experience. For starters, the stories and bedtime tales he'd hear would be filled with grotesque and nightmarish content. This could lead to him having a very different perception of the magical world. Instead of seeing Hogwarts as a place of wonder and learning, he might view it with suspicion, thinking there are hidden, malevolent forces everywhere. His friendships would also be affected. He might attract those who are into the darker side of magic, and repel those with more traditional values. His magical abilities could develop in an unorthodox way too, perhaps focusing more on defensive and dark - arts - like spells out of a sense of self - preservation.
In many Harry Potter fanfics, the concept of dementors often adds a dark and mysterious element. When it comes to wand cores, there could be a fanfic where a character discovers a new type of wand core that has been affected by dementor magic. This could lead to a whole new set of spells and abilities for the wizard or witch who wields it. The wand might have an affinity for dark arts - like spells, but also might be able to counteract the effects of dementors on a person's soul, creating a very complex and morally ambiguous magical item.
In Harry Potter, dementors behave like villains. Dementors guarded the Wizarding Prison in Azkaban, and when they were under the control of the Ministry of Magic, they were capable of feeding on people's pleasure and souls. The environment they passed through became cold, and they would absorb people's happiness and remind people of terrible things. Their "Dementor's Kiss" could suck people's souls and turn them into zombies. Later, the dementors even joined Voldemort's camp to fight for Voldemort. This series of actions shows that they are extremely harmful to the protagonist and other positive characters. So from this point of view, dementors are bad. But from another perspective, they were just magical creatures with special abilities and settings written by Rowling. Their behavior was based on the setting of the story and the development of the plot. Harry Potter and the Goblet of Fire was not enough. Everyone, please click to read the novel!
In a 'Harry Potter raised by Burt Gummer' fanfic, Harry would likely have a unique set of values. Burt Gummer is all about facing the unknown and being self - reliant. So Harry might not be as meek as he was initially in the books. He could be more confident in dealing with dark forces early on. Also, his magical abilities might be combined with Burt's practical skills in a really interesting way, like using magic to enhance Burt's weapons or traps.
If Harry Potter were raised by Jack Frost in a fanfic, it would be a wild ride. Jack Frost is often depicted as a bit of a loner and a trickster. Harry could inherit these traits. His magic would likely be a blend of Hogwarts - style magic and Jack Frost's ice powers. He might use his ice powers to create magical ice sculptures that have real magical properties. His relationship with Hogwarts itself could be different. Instead of being in awe of the castle like most students, he might see it as just another place, and be more interested in the frozen landscapes around it. Also, his dueling style could be very unique, incorporating ice attacks and defenses that would surprise his opponents.
Well, he'd probably grow up with some very different skills. He might learn how to use Thor's hammer instead of a magic wand at first. And he'd be surrounded by high - tech gadgets from Stark, which could be really cool. Also, he'd have the Avengers' sense of justice drilled into him from a young age.
