Well, in the 'harry talks about the dursleys fanfic', it might be fascinating to see how Harry describes their daily routines. It could give us a deeper understanding of the Dursleys' world from Harry's point of view. He might talk about how their obsession with normalcy affected him and how he coped with it during his time living with them.
The fanfic adds a new dimension to the story. It allows us to see the Dursleys from Harry's eyes in a more in - depth way. He could talk about things like the small acts of kindness or cruelty that the Dursleys showed him, which can change how we view their relationship. Also, it might explore how his time with the Dursleys shaped his view of family and the muggle world in general, thus enriching the overall Harry Potter story universe.
In this fanfic, the Dursleys' normal, Muggle - centered life is disrupted by the appearance of a Nundu. Harry's pets could be the key to resolving the situation. Suppose Harry has a pet Kneazle that can detect the Nundu's intentions. The Kneazle could communicate in its own way to the Dursleys (even if they don't fully understand) and lead them to safety away from the Nundu.
I'm not sure specifically as it's a rather dark and non - canon fanfic concept. It might explore the extreme abuse Harry could have faced at the hands of the Dursleys taken to a fatal level, perhaps delving into themes of neglect and violence in a very different take on the Harry Potter universe.
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.
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.
In this fanfic, the Dursleys may be depicted as being in over their heads. Vernon Dursley, for example, might be shown as constantly angry and trying to assert his authority in a situation where he has none. Petunia Dursley could be portrayed as being torn between her dislike for magic and her sense of family obligation towards Harry. Dudley might be shown as being bullied or affected in the Muggle world because of Harry's presence in their family.
One great 'sirius talks to harry fanfic' could be 'Sirius's Guidance'. In this fic, Sirius gives Harry valuable advice on dealing with the challenges at Hogwarts and in the wizarding world. It really delves deep into their relationship.
In the fanfic, Snape might use his knowledge of the Dursleys' house layout. He may enter the house unnoticed, find Harry, and then use a Portkey to quickly get them both out of there. He could also have some sort of charm or potion that he uses to counter any magic the Dursleys might have used to keep Harry there, like a spell - breaking potion. And he may have planned the whole rescue very carefully, choosing a time when the Dursleys are least likely to notice, like in the middle of the night.
The abuse makes Harry more cautious. He has learned from the Dursleys that the world can be cruel, so he's careful about who he trusts. For example, he might be hesitant to open up to new people he meets at Hogwarts.
