In some fanfictions, Harry might find out he's a wizard through a different magical being rather than Hagrid. For example, a mysterious wizard who has been secretly watching over him all along reveals the truth. This could lead to a whole different dynamic as Harry might initially be more suspicious of this new figure compared to Hagrid.
One of the most interesting aspects in this type of fanfiction is seeing Harry's initial shock. He has grown up in a non - magical world, so suddenly realizing he's a wizard would be overwhelming. He might first doubt it, thinking it's some kind of joke or mistake. But as the story unfolds, he starts to see the evidence around him, like strange things happening that can't be explained by Muggle means.
Some fanfictions add an older wizard as a mentor figure. This wizard could have a different view on magic compared to Dumbledore and might teach Harry some more unorthodox magic. This adds a new dimension to Harry's learning about the wizarding world.
One possible plotline could be Harry struggling to adapt to the new social expectations of being a girl in the wizarding world. For example, she might face different treatment from her male friends at Hogwarts.
One interesting plot development could be how Harry deals with the reactions of his friends. For example, Hermione might be initially shocked but then become very supportive, using her vast knowledge to research about this unprecedented situation for a male wizard. Ron, on the other hand, could be more comically bewildered and struggle to come to terms with it.
One interesting plot could be Adrian's initial shock and then his realization of all the times Marinette's behavior as Ladybug made sense in her civilian form. For example, her courage as Ladybug might be seen as her standing up to Chloe in her Marinette guise.
One interesting plot could be Valerie finding out about Danny's ghost powers in a very public and dangerous situation. Maybe they are in the middle of a fight with a powerful ghost and Danny has no choice but to reveal himself to save Valerie. Another plot could be Valerie slowly suspecting Danny over time as she notices little things about his behavior that seem strange in relation to the ghost attacks. For example, he always seems to disappear right before a ghost shows up.
Well, in some of these fanfictions, there could be a plot where the demi - wizard discovers new magical abilities that are a blend of wizard and other magical creature powers. For example, they might be able to communicate with magical plants in a way that normal wizards can't.
One possible plot could be that the twin has been hidden away by some dark force all this time. When Harry discovers the twin, they have to figure out how to break the spell or curse that was placed on the twin. Another plot might be that the twin has been living in the Muggle world, unaware of their magical heritage, and Harry has to introduce them to the wizarding world and they face various challenges together.
In some fanfictions, Harry might get out of town to escape the constant danger and media attention. He could end up in a small, peaceful village where he learns new, non - combat magic skills and forms unexpected friendships.
Often, there are plots centered around secrecy. Harry might worry about how others will react, like his friends Hermione and Ron. So, he tries to keep his relationship with his mates a secret. And then there's the plot of the mates themselves getting to know each other better. Since they are all in a relationship with Harry, they need to form their own bonds too, which can lead to some really interesting interactions and storylines.
