A frequent theme is the exploration of the dark side of magic. Since Harry has always been associated with the light side of magic in the original series, in these fanfictions, he delves into the darker, more forbidden aspects of magic. Also, there is often the theme of revenge. Harry might seek revenge on those who he feels have wronged him in the past, which leads him down an evil path. This is a big departure from the forgiving nature of the original Harry Potter character.
One common theme is manipulation. Writers may show Dumbledore as using Harry and others for his own secret ends. Another theme could be misinformation. They might depict Dumbledore as spreading false information to keep control. Also, power - hungry is a theme, where Dumbledore is seen as being after more power than he lets on.
One common theme is Harry being corrupted by dark magic. Maybe he's influenced by a powerful dark wizard or some dark artifact. Another theme could be a twisted version of Hogwarts, where instead of a place of learning and growth, it becomes a den of evil. And sometimes, his friends might turn against him in these dark versions.
A frequent theme is the subversion of the original power structure. In many of these fanfictions, Harry becomes so powerful that he challenges the Ministry of Magic or Hogwarts' traditional hierarchy. He might form his own group or alliance with characters who were previously on the fringes, like the Slytherins who also have a taste for power and a more complex view of magic. And also, the exploration of his connection to Voldemort in a more complex way, not just as an enemy but as a source of some kind of power or knowledge is quite common.
A common theme is the discovery of new powers. Harry suddenly realizes he has abilities that were previously unknown, like the power to communicate with magical creatures on a deeper level. This makes his connection to the wizarding world even more profound.
One common theme is the idea of self - discovery. Harry often finds out about his newfound wealth and power in a way that makes him reevaluate who he is. For example, he might question his relationships with his friends when he realizes he has so much more to offer. Another theme is the change in power dynamics. With his new power and wealth, Harry is no longer at the bottom of the social ladder in the wizarding world. This can lead to conflicts with those who were used to being in control.
One common theme is the corruption of power. In these fanfics, Harry often has a different view of his magic power and uses it for less noble purposes compared to the original story. For example, he might use it to seek revenge or gain control over others.
One common theme is the clash of two different worlds. The magical world of Harry Potter and the post - apocalyptic, horror - filled world of Resident Evil collide. Another theme is survival. Characters from both universes have to figure out how to survive in a new and dangerous environment.
One common theme is betrayal. Since Dumbledore is made evil, Harry feels betrayed by someone he once trusted. Another theme is power struggle. With Harry being godlike, there's a struggle between his new - found power and Dumbledore's devious plans.
One common theme is the corruption of characters. For example, a once - good character like Ron or Hermione might be tempted by dark magic and gradually turn evil. Another theme could be the discovery of hidden evil in the wizarding institutions, like Hogwarts having a dark secret beneath its surface. And sometimes, it's about the evil that lurks in the hearts of the characters due to past traumas or family legacies.
One common theme could be the exploration of their combined magical abilities. Since both Harry and Fleur are powerful in their own ways, fanfictions might show them using their magic to overcome great challenges.
