One unique Harry Potter fanfiction could be one where Harry is sorted into Slytherin and has to deal with the prejudice from his Gryffindor friends. Another might be a story where the Marauders survive and have to adapt to a post - Voldemort world. And then there could be a fanfic where Hermione becomes a Hogwarts professor much earlier than expected.
There are also fanfictions that focus on the backstories of minor characters. For instance, a story about Neville's parents before they were tortured into insanity. It could explore their time at Hogwarts, their relationships, and how they got involved in the fight against Voldemort. This gives a whole new perspective to the overall story.
Some fanfictions give characters the ability to communicate with animals on a much deeper level than normal in the Harry Potter world. Instead of just understanding general emotions or simple messages, they can have full - blown conversations. This could lead to uncovering secrets that the animals have witnessed, or using them as spies in a battle of wits against the dark forces.
One interesting weapon in Harry Potter fanfiction is a crystal orb that can absorb and redirect spells. It can be used defensively by soaking up an incoming curse and then sending it back at the caster. Another unique weapon is a cloak that has the power to make the wearer invisible not just to the naked eye but also to magical detection spells. Some fanfictions also feature a gauntlet that enhances the physical strength of the wearer as well as their magical abilities when they cast spells through it.
A unicorn Patronus is another special one. Unicorns are known for their purity and magic. In fanfiction, a character with a unicorn Patronus might be pure of heart and have a deep connection to the more innocent and natural aspects of magic. They could be more in tune with the forest and the magical creatures that live there, and perhaps have the ability to heal or soothe others with their magic.
Some unique ideas could be that baby Harry has a special bond with magical creatures from a very young age. For instance, he might be able to communicate with Hedwig even as a baby, through some kind of magical telepathy. This could set up a whole different dynamic in the story.
One idea could be a character who uses Dirty Harry - like tactics to deal with the Death Eaters. For instance, being extremely direct and fearless in the face of danger, much like Dirty Harry in his movies.
It's unique in that it gives fans the creative freedom to rewrite the story, add new elements, or change the course of events. Fanfiction writers can take a minor character like Luna Lovegood and make her the central figure in a story, which can provide fresh insights into the HP universe. Also, it can explore different time periods within the wizarding world or even introduce new magical creatures. It's a way for fans to put their own spin on the beloved Harry Potter series.
In some 'Harry Potter Harem' fanfictions, a unique idea is to have the 'harem' members be those who have been wronged by the dark side in different ways. They bond with Harry as they all strive for justice and a better wizarding world. For instance, a character whose family was destroyed by Death Eaters joins Harry's group. This creates a deep emotional connection among the group members and a strong motivation for their actions. It also gives a new perspective on the fight against evil in the Harry Potter universe, as they work together not just for Harry's sake but for their own and the world's.
Some fanfictions feature unique magic related to memory manipulation. Instead of just using the Obliviate spell, there could be a more complex form of magic where one can not only erase but also rewrite memories in great detail. There might also be a type of magic that is based on the constellations, where wizards can draw power from the alignment of the stars. Additionally, a unique magic could be the ability to transform into mythical creatures, not just the Animagus transformation we know from the books, but into something more fantastical like a phoenix or a dragon.
Well, in some fanfictions, Loki might be interested in the Time - Turner device from the Harry Potter universe. He could try to use it for his own purposes, like going back in time to change certain events in the wizarding world to his advantage. Or perhaps Loki and Harry Potter get into a magical duel where Loki uses his Asgardian magic and Harry uses his wizarding spells. The contrast between their different forms of magic would be really interesting to explore in a fanfiction.
