There is a fanfiction that explores what would happen if the Avada Kedavra curse was used on a magical creature instead of a human. It shows how the curse affects the creature differently and how the wizarding world has to deal with the consequences. It's full of interesting details about magical creature lore and the power of the curse.
In some fanfictions, Avada Kedavra is used as a way to explore the darker side of characters. For example, a character who was previously seen as good might be forced to use it in self - defense, which then causes them to struggle with guilt. It can also be used to create alternate universes where the spell has different effects or consequences.
In my opinion, it depends on how it's done. If the fanfiction is using Harry using Avada Kedavra in a context that is meant to shock and go against the core values of the series just for the sake of being edgy, then it's unethical. But if it's part of a well - thought - out exploration of the character's growth, for example, if Harry is corrupted by dark magic in an alternate universe, and the story is used to teach a lesson about the dangers of straying from one's values, it could be seen as a valid creative piece.
One ethical dilemma is when a 'good' character has to decide whether to use Avada Kedavra. In the original series, it's an unforgivable curse, but in fanfiction, authors might put their characters in situations where it seems like the only option. For example, to stop a powerful dark wizard who is about to kill many innocent people.
One possible plotline could be an alternate universe where Harry is turned to the dark side early on. Maybe he discovers some false information about his parents' death and blames the wizarding world, leading him to use Avada Kedavra on those he believes are responsible.
One interesting 'Harry Potter Avada Kedavra' fanfiction could be one where a character manages to reverse the effects of the Avada Kedavra curse through some ancient magic. In this type of fanfiction, it might explore the idea of life after being hit by the Killing Curse and how magic can be used in ways not previously thought of in the original series.
Well, perhaps in the fanfiction, Draco Malfoy is researching a way to counter the Avada Kedavra. He could be secretly working with some of the more intelligent and magically inclined students at Hogwarts. They might be trying to find a protection spell that can block the Avada Kedavra. This could lead to a lot of sneaking around, secret meetings in the Room of Requirement, and tense moments when they think they're about to be discovered by the Death Eaters or other dark forces.
There's a fanfiction called 'James Potter: Beyond the Veil'. In this story, after James' death, his spirit gets trapped in a strange realm beyond the veil. Harry, through some unforeseen circumstances, is able to communicate with his father's spirit. Together, they have to find a way to break free from this realm and also prevent a dark force from using this connection between them to gain access to the living world. It's a very different take on the relationship between James and Harry.
I've read one where Cibola was like a hidden magical library that only a select few in the Harry Potter universe knew about. Harry stumbles upon it and finds out that it holds the key to a powerful magic that could defeat Voldemort once and for all. It was really unique as it combined the mystery of Cibola with the main plot of the Harry Potter series.
Sure. There's one where Stonehenge is actually a magical prison for an ancient and extremely dangerous dark wizard. Harry and his friends accidentally release the wizard and then have to find a way to re - imprison him using the magic of Stonehenge itself. It's full of action and mystery.
There's a great fanfiction called 'Professor Snape's Unseen Allies'. It has a unique plot where Snape is not as alone as he seemed in the original story. He has a group of underground allies within Hogwarts, including some of the other professors, who are helping him in his mission to protect Harry. It gives a whole new perspective on Snape's actions and his relationships with the other faculty members. This fanfiction is full of twists and turns that keep you hooked from start to finish.
