In this kind of fanfic, perhaps Harry has finally had enough of the Dursleys' mistreatment. He might use his magic in a moment of rage. Maybe he starts by levitating Dudley to teach him a lesson after one too many taunts. Or he could use a spell to make Aunt Petunia's precious china smash, as a way of getting back at her for all the years of neglect and cruelty.
The main characters are Harry, who has reached his breaking point with the Dursleys. His pent - up anger and frustration towards them finally explodes into action. The Dursleys, on the other hand, are the recipients of Harry's wrath. Uncle Vernon, with his blustering and bullying ways, Aunt Petunia, who has always been cold and distant, and Dudley, the spoiled brat. There could also be appearances from characters like Dumbledore, who might show up to either reprimand Harry or offer some kind of guidance depending on the nature of the attacks.
In this fanfic, Sirius could be tipped off that the Dursleys are planning to send Harry away to some even worse place. So he swoops in. They flee to a remote wizarding village. There, Harry meets other wizards and witches who are sympathetic to his cause. Sirius helps Harry train in combat magic, as he anticipates future battles. Harry also gets to explore his magical heritage more freely without the Dursleys' restrictions.
In most ethical views, it's not. Harry was raised by the Dursleys, and while they were cruel to him, torture is an extreme form of revenge. In the world of fanfic, some might explore this idea for shock value or to show a 'dark' side of Harry. But from a moral standpoint in general, it goes against the principles of kindness and non - violence that are often promoted.
In this fanfic, the Potters could have faked their deaths all along. They come back to rescue Harry when they find out how horribly the Dursleys are treating him. They might bring some magical creatures with them to help. For example, a phoenix that can heal Harry if he has any injuries from the Dursleys. Then they take Harry with them on a magical journey to a hidden wizarding community where they can all be safe and happy.
In some 'Harry Potter and the Dursleys' fanfics, there's a plot twist where the Dursleys are actually protecting Harry from a greater threat that the wizarding world doesn't even know about. They've been cruel to keep him close and safe. Also, there could be a twist where Vernon Dursley has a connection to the wizarding world through his family's past that he's been trying to hide all along, which changes how we view his hatred for magic.
Well, perhaps Daphne somehow discovers Harry's awful situation at the Dursleys. She might use magic to break into the house secretly. Then she could use a spell to make the Dursleys forget about Harry so that she can take him away without a fuss.
It could be that a non - human magical being, like a centaur or a house - elf with a strong sense of justice, takes Harry from the Dursleys. They might see the abuse and neglect he endures and decide to act. This could lead to Harry having a completely different perspective on the magical world as he's exposed to aspects of it that are not typically part of a human - centric view.
Probably not. The idea of Harry being beaten to death by the Dursleys is extremely dark and goes against the general spirit of the Harry Potter series. Most fans are more interested in positive, adventure - filled, or character - development - centered fanfics.
One possible plot development could be that Harry discovers his magic earlier on his own due to the neglect. He might start exploring the wizarding world secretly, finding hidden magical artifacts in the neighborhood. Another could be that he forms an unexpected alliance with the local magical creatures that sense his isolation. Maybe he even starts teaching himself basic spells from an old, dusty spellbook he finds in the attic.
Perhaps in this fanfic, Severus doesn't just save Harry physically from the Dursleys. He also saves Harry from the emotional and psychological damage that the Dursleys have been inflicting on him. Severus, having his own traumatic past, might be able to relate to Harry on a deeper level and starts to mentor him in ways that Dumbledore never could. This could lead to a completely different Harry, more confident and less impulsive.
