In some fanfiction, Harry hides his identity because he discovers a prophecy that his true self being known will put everyone in great danger. So he leaves Hogwarts and lives among muggles for a while. He suppresses his magic in a way that not even the most powerful wizards can detect him, and he has to relearn how to use his magic in secret when the time comes to face the new dark forces.
There could be a fanfic where Harry hides his identity to protect his friends. He fakes his own death and then secretly works to undermine Voldemort's forces. In this story, he might use polyjuice potion to assume different forms and move among the Death Eaters unnoticed. This way, he can gather crucial information for the Order of the Phoenix.
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 good example could be a story where a character in the Harry Potter universe, perhaps a minor wizard or witch, is born with a heart disease and has to struggle with it while also dealing with the magical world's challenges. They might face discrimination from some pure - blood families who think a weak body means a weak magic ability. Another could be a story where a spell gone wrong causes a heart disease - like condition in a Hogwarts student, and they have to find a magical cure.
There could be a fanfiction where Ron is jealous of Harry's fame again and acts out in a way that almost ruins their friendship. However, Hermione helps Ron see the error of his ways. Harry, seeing Ron's remorse, forgives him. This then leads to a series of adventures where the three of them face new challenges, with their friendship on a more solid footing because of the forgiveness.
There might be a fanfic in which a master Occlumens is a student at Hogwarts. They are secretly protecting the school from dark forces that are trying to use Legilimency to gain access to certain secrets. This can lead to interesting interactions with the professors and other students, as they try to figure out who this mysterious Occlumens is.
One great example could be 'The Dragon's Bond with Harry'. In this fanfic, it might explore how Harry discovers his connection to dragons, perhaps through a hidden magical bond. Another could be 'Dragon Riders in the Potterverse', which could involve characters becoming dragon riders in the Harry Potter world. There's also 'A Dragon's Affection for Harry', where a dragon shows an unusual attachment to Harry, leading to all sorts of magical adventures and challenges.
In some fanfictions, Harry might change his identity to protect his friends. For example, if Voldemort was specifically targeting those close to Harry, he could change his look and name so that his friends would no longer be in danger. He could also change his identity to study dark magic secretly in order to better understand Voldemort's power and find a way to defeat him without putting others at risk.
One example could be a fanfiction where Harry is mortified when he accidentally uses the wrong spell in front of the whole school during a big event. It shows his embarrassment and how he has to deal with the aftermath.
One example could be fanfictions that explore the darker side of the wizarding world politics. They might show how power-hungry wizards manipulate situations, similar to how Umbridge was able to gain so much power in Hogwarts. Another could be ones that focus on the jaded view of the main characters as they grow up. For instance, Harry might start to question the true motives of Dumbledore after learning more about his past decisions. And there could be fanfictions that show the cynical view of the Hogwarts houses, like how Gryffindors might be seen as glory - seekers rather than just brave.
There might be a fanfiction where Draco Malfoy, trying to prove himself in a different way, gets into bodybuilding. He starts secretly training in the dungeons of Hogwarts. This fanfic could explore how his new physique and strength change his relationships with other students and his self - perception within the Slytherin house.
Some good Harry Potter framed fanfiction includes those that imagine alternative endings. For example, what if Voldemort had won? There are also fanfictions that center around time - travel, like a character going back in time to change certain events in the wizarding world. Fanfictions that expand on the magical creatures and their habitats within the Harry Potter world are also quite popular. They might describe in detail the life of a hippogriff or a thestral in a way that wasn't fully explored in the original books.
