How does Harry's life change when he lives with dementors in fanfiction?

Well, it could change the plot in many ways. For example, he might be able to negotiate with them. Maybe he can convince them not to attack people, which would make Hogwarts a much safer place. He could also learn more about their origin and motives directly from them, instead of just speculating as others do.

His relationship with magic could also transform. Without the support of the wizarding community, he may start to explore magic in his own way. He could discover new spells or magical abilities that are not taught at Hogwarts. This newfound knowledge might be a double - edged sword. On one hand, it could help him survive as an outcast. On the other hand, it could further isolate him as it makes him even more different from the others.

His life might become more self - contained. He'd have to rely more on himself without the big support system of Hogwarts. He might become more resourceful, like finding new ways to cook with limited space and resources in the tiny house.

He'd be much more somber. Dementors drain happiness, so he'd lack the cheerfulness that normal Harry has.

His life could change drastically. He might start to see the magical world in a different light earlier than in the original. For example, he could meet some early allies or enemies right after getting the letter.

When Harry Potter becomes part phoenix in fanfiction, his relationship with the magical world around him would shift. He could communicate with other phoenixes in a way normal wizards can't. This would give him access to knowledge and secrets that are hidden from others. Also, his role in the wizarding community would become more special. People would look at him not just as the boy who lived, but as a unique being with the powers of a phoenix. He might be seen as a symbol of hope and renewal, much like the phoenix itself.

His daily routine would be completely different. Instead of going to classes like Potions and Transfiguration, he'd be in Math and History classes. He might feel bored at times because he's used to the more exciting and magical learning at Hogwarts.

In fanfiction, if Harry lives with dementors, it would be a very dark and challenging situation. Harry might constantly be in a state of fear and depression. The dementors' presence would likely drain his happiness and positive emotions. He might have to find ways to resist their influence, perhaps by using powerful Patronus magic more frequently.

It could also be due to his own inner strength and growth as a wizard. Harry has faced so many challenges and traumas throughout his life. His experiences might have awakened a latent power within him that allows him to control dementors. His strong willpower and determination, which have been developed over years of fighting against the dark forces, could be the key factor in this newfound ability.

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.
