It's not common at all. The Harry Potter world is mainly associated with magic, friendship, and fighting against evil. Suicide is a dark and heavy topic that doesn't really fit with the general feel of the franchise. Most fanfiction focuses on expanding on the existing adventures, relationships, or exploring new magical elements rather than such a negative and out - of - character scenario.
It's controversial. Naruto and Sasuke have a long - standing relationship that fans have come to expect a certain development from. Naruto has always been trying to save Sasuke, not kill him. In fanfiction, while there is creative freedom, this concept is against the grain. But some writers might use it to show a extreme breakdown of their relationship due to some unforeseen and very dark circumstances, like if Sasuke was completely consumed by evil and there was no other way. Still, most fans would be shocked by this idea.
It's controversial. Naruto's whole journey in the original series is centered around protecting Konoha and its people. A fanfiction with him killing Konoha completely subverts that. But it could be an interesting exploration in terms of alternate universes. Still, in the general Naruto fandom, it's not a popular or common theme as it clashes with the established character arcs and the overall positive image of Konoha in the original work.
It is a rather controversial theme. In the Harry Potter fandom, Harry is a beloved main character. Having Draco kill him goes against the general heroic narrative and the idea of good triumphing over evil that is prevalent in the original series. Most fans prefer fanfics that stay true to the spirit of the books, where Harry is the hero and Draco is more of an antagonist who may reform, not a murderer.
It's not common. Most Naruto fanfictions tend to focus on positive relationships between the characters. Hinata is often portrayed as someone who would protect Naruto rather than kill him. But in some out - of - the - box fanfictions, this might be used to show a drastic change in the character's personality or a completely different plotline.
It's a very controversial theme. In the Naruto canon, Kushina is Naruto's mother and they have a loving bond that is a fundamental part of the story. A fanfic with such a premise goes against the essence of their relationship. It would likely shock and upset many fans who are attached to the positive family dynamics in the original series.
In the normal 'Harry Potter' lore, Harry's parents are killed by Voldemort. A 'harry kills his parents fanfic' is a very non - canonical and controversial idea. It goes against the basic premise of the original story where Harry is an orphan because of Voldemort's evil deeds. Fanfics like this might explore very dark and alternative universes where Harry is somehow made into a villain who kills his own parents. However, such themes can be disturbing to many fans who are attached to the original story's values and characterizations.
It's controversial. The Dursleys were Harry's only family (albeit a horrible one) in the Muggle world. Killing them in fanfiction is a very dark take. It's not common because most fanfiction either focuses on the magical adventures, Harry's relationships at Hogwarts, or redeeming the Dursleys rather than such extreme and immoral actions. The original series promotes forgiveness and growth, not revenge - killing.
Definitely. In the original story, there are good and bad characters among both Purebloods and non - Purebloods. Making Harry a killer of Purebloods in fanfiction simplifies the complex moral landscape of the wizarding world and is likely to stir up strong reactions from fans who value the original moral and ethical framework.
It's a very controversial theme. In the original 'Harry Potter' series, both Snape and Dumbledore are complex and important characters. Dumbledore is a mentor figure to Harry, and Snape has a very complicated relationship with Harry as well. For fans who love the original story, the idea of Harry killing them goes against the essence of the characters' development and the overall moral and emotional fabric of the series.
Yes, it is a somewhat common theme in some fanfictions. One reason could be the complex relationship between Harry and Snape in the original series. Snape was often cruel to Harry, so in some alternate universes, writers explore the extreme scenario of Harry killing Snape. It also allows for exploring darker aspects of Harry's character and the consequences of such an act within the wizarding world.
