What could happen to Harry after he is removed from the Dursleys in fanfiction?

They would probably be horrified. The Dursleys detested all things related to magic in the original Harry Potter story. Fanfiction might introduce new and strange magical concepts that would go against their Muggle - centric and magic - hating views.

Well, one possibility is that Draco would be completely out of his element at the Dursleys'. He's used to luxury and magic, while the Dursleys' house is a non - magical and rather dull place. He might start to understand Harry's pre - Hogwarts life better. For example, he could see how Harry was treated like an outcast, which might change his view of Harry. Maybe they'd bond over their shared dislike of the Dursleys' rules and behavior towards them.

Well, perhaps Harry would start by making the Dursleys' house a bit of a chaos. He could make the stairs creak whenever Uncle Vernon is trying to sneak around, or make Aunt Petunia's precious china rattle whenever she is being particularly mean. He might also use magic to make Dudley's new clothes look like old rags in front of his friends, which would be quite embarrassing for him.

In this fanfiction, Harry might grow up with a different personality. Maybe he'd be more meek at first, having been constantly put down by the Dursleys. He could have a hard time discovering his magic, as the Dursleys would surely try to hide it from him. For example, he might find strange things happening around him but be too afraid to tell anyone because of the Dursleys' strict control.

Well, in this kind of fanfiction, Harry might meet some new magical creatures unique to Canada. Maybe he'll encounter a friendly Canadian werewolf who helps him hide from any threats sent by the Dursleys or Voldemort's followers.

If the Dursleys watched Harry Potter fanfiction, it would be a complete shock to their system. They have spent so long suppressing Harry's magic and trying to keep their world as normal as possible. Fanfiction often explores different aspects of the wizarding world, some of which might be quite extreme or different from what they think they know. They might initially be very confused, and then probably angry that such things exist. They could also try to stop Harry from having any access to it, thinking it would further fuel his 'unnatural' interest in magic.

In this type of fanfiction, one possible scenario could be that Harry's already difficult life at the Dursleys takes a fatal turn. Maybe the neglect and abuse he endures finally become too much for his young body to bear. For example, he could be severely underfed and fall ill without proper medical attention, leading to his death. It would also have a huge impact on the wizarding world. Since Harry was seen as the 'Chosen One', his death might cause chaos and despair among those who were hoping he would defeat Voldemort.

His confidence might grow a great deal. Without the Dursleys constantly putting him down, he would start to believe in himself more. He'd be more willing to take risks and show his true abilities.

In fanfiction, when Harry and Ginny meet the Dursleys, there could be a lot of tension. The Dursleys are not fond of anything related to magic. Ginny, being a confident witch, might stand up to the Dursleys' rudeness towards Harry. Harry, on the other hand, would be in an awkward position as he has to deal with his Muggle family and his magical girlfriend at the same time. There could be some humorous exchanges as Ginny tries to understand the strange Muggle world of the Dursleys while also showing them that magic is not something to be feared.

In some fanfictions, Hermione might use her intelligence and magic skills. For example, she could use a powerful spell to create a distraction at the Dursleys' place. Maybe a spell that makes all the dishes in the kitchen start flying around, causing chaos. Then, while the Dursleys are distracted, she could quickly grab Harry and apparate away to a safe place, like the Burrow or a hidden wizarding location she has prepared in advance.
