One more unique fanfiction could be about his first time seeing the Hogwarts ghosts. He could be both scared and fascinated at the same time. The fanfic could explore how he learned about the history of the ghosts and how they interacted with the students. It could also show his gradual acceptance of the more unusual aspects of Hogwarts life.
A fanfiction could center around his first encounter with the Sorting Hat. It could be a detailed account of his thoughts and feelings as the hat deliberates which house to put him in. Maybe he has a conversation with the hat in his mind, pleading to be in Gryffindor like his parents.
One idea could be a story where a new student arrives at Hogwarts with the ability to create ice sculptures that come to life. The ice creatures could either help or hinder the main characters in their adventures. For example, they could assist in a battle against the dark forces by freezing the enemies' wands. Another idea is that the ice - making magic is a lost art that Harry discovers in an old, forgotten book in the restricted section of the library. He then has to learn and master it secretly to use it against Voldemort in a final showdown.
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.
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.
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.
A Harry Potter and Star Wars crossover would be really interesting. Picture Harry and his friends traveling through space in the Millennium Falcon, learning about the Force and using their magic in combination with Jedi skills to fight against a new dark threat that combines the power - hungry Sith and the dark wizards from the Potterverse.
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.
A unique idea could be that a Transformer is enchanted by a wizard to be able to use magic. So it becomes a sort of magical - mechanical hybrid. It could use spells like the wizards and also transform into different forms. For example, it could transform into a broom - like form to fly around Hogwarts.
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.
One unique concept could be magic tattoos. In some fanfics, wizards have tattoos that store magic or can be activated to perform spells. For example, a tattoo of a phoenix might allow a wizard to burst into flames briefly for protection. Another is magic based on constellations. Wizards might draw power from the alignment of the stars, and spells could be more powerful during certain celestial events.
Another unique one is 'Hogwarts, a History of Magic'. It's not just a simple retelling. Instead, it weaves together different historical events in the wizarding world related to Hogwarts in a very creative way. It's like getting a deeper, more detailed look at the history of Hogwarts than what we got in the original books.
