Well, in many'mistaken' Harry Potter fanfictions, misunderstandings play a huge role. If we assume 'ladyraye' follows some of these common trends, there might be situations where spells go wrong and cause characters to be misperceived. Also, relationships could be affected by these mistakes. For instance, a character might mistake the intentions of another character in a romantic context, leading to all sorts of drama. Another common element could be the misinterpretation of prophecies or magical artifacts, which then leads to a chain of events based on the wrong assumptions.
I'm not specifically familiar with 'ladyraye' Harry Potter mistaken fanfiction. But you can try searching on fanfiction websites like FanFiction.net or Archive of Our Own. They have a vast collection of Harry Potter fanfictions, and you might be able to find the ones related to this specific 'mistaken' theme there.
A third common theme is adaptation. When Percy is mistaken for a Harry Potter character or vice versa, he or the other character has to adapt to the new world they find themselves in. They have to learn new rules, make new friends or enemies, and find their place. This can involve Percy trying to blend in at Hogwarts or a Harry Potter character trying to survive at Camp Half - Blood.
There are some works that might be mistaken for Harry Potter fanfiction. For example, books with a similar magical school setting. If a story has a young protagonist attending a hidden school where they learn magic, spells, and have adventures, it could be misidentified as Harry Potter fanfiction. Another case could be when a story features magical creatures that are also in the Harry Potter universe, like wizards, witches, and mythical beasts.
One example could be a new student being mistaken for a long - lost heir to a powerful wizarding family. Everyone starts treating them differently, expecting great things from them, while the real heir is hidden away. Another might be a character who looks similar to a wanted criminal. They are constantly chased by the Aurors until the truth is discovered. And sometimes, a Muggle - born might be mistaken for a wizard with a dark past just because of some strange magical occurrence around them.
One common theme is identity confusion. Harry has to deal with the fact that people see him as someone he's not, which makes him question his own identity in a way.
If Harry Potter is mistaken for Loki fanfiction, there would be a huge clash of universes. Fans of both might be either outraged or find it oddly interesting. For one, the magic systems are completely different. Harry Potter's magic is more about spells and potions, while Loki's is more of a godly, illusory kind. It would be a mess of expectations and interpretations.
One reason is the setting. If a story is set in a world filled with magic, like a hidden magical town or a school for magic, it can remind people of Harry Potter. For instance, a story about a young wizard going to a school with different houses and learning magic from various teachers might be thought of as Harry Potter fanfiction.
A possible plot in 'Harry Potter mistaken for Elfling fanfiction' is that the magical community outside of Hogwarts mistakes Harry for an elfling. They assume he has elven heritage due to some old prophecy. This leads to him being involved in elven politics and power struggles. Harry has to use his wits and the little he knows about the elves to survive. Along the way, he makes friends with some elves who help him understand his situation better and eventually he clears up the misunderstanding.
Common elements may include the portrayal of a tyrannical regime. In 'Harry Potter', Voldemort's regime is one of fear and control, much like the Nazi regime. There could be a focus on the experiences of the persecuted. For instance, how Muggle - borns in 'Harry Potter' are treated can be compared to how the Jews were treated. Additionally, the role of the bystanders can be explored. In both the 'Harry Potter' world and the Holocaust, there are those who stand by and those who take action. This can be a central element in such fanfiction as it makes readers think about moral responsibility.
One common element is the use of Hogwarts as a setting. It's such an iconic place that many fanfictions are set there. Another is the presence of the main characters like Harry, Hermione, and Ron. Their relationships and personalities are often explored further. Magic spells are also common. Writers might introduce new spells or use existing ones in different ways.
