Had I known Harry Potter fanfiction, what are the most popular themes in it?

One of the most popular themes is alternate universes. Fans love to imagine what would happen if certain events in the original story were different. Another popular theme is character relationships, especially the romantic relationships between characters like Harry and Hermione, which deviate from the original pairings. And of course, there are a lot of fanfictions that focus on the dark side of the wizarding world, exploring how Voldemort could have been even more menacing or what other dark wizards might be out there.

One popular theme is identity. Since Metamorphmagi can change their appearance, fanfictions often explore how this affects their sense of self. Another theme is secrecy. They might have to hide their ability, which creates interesting plotlines.

One of the popular elemental themes is the use of fire. It often represents power and passion. Many fanfictions have characters who can conjure and control fire in unique ways, like creating phoenix - like flames. It gives a sense of danger and intensity to the story.

One of the most popular themes is the 'What if' scenarios. For example, what if Harry had been sorted into Slytherin? Another common theme is the exploration of character backstories that J.K. Rowling didn't fully delve into in the original books, like the early life of Severus Snape. And relationships, not just romantic ones but also friendships, are often explored in-depth. For instance, the friendship between Harry, Ron and Hermione from different perspectives.

One popular theme is the clash of cultures. The very different natures of the wizarding world and the Xenomorphs' universe make for an interesting contrast. Another is survival, as characters from the Harry Potter world have to figure out how to survive against the deadly Xenomorphs. And of course, there's the theme of magic vs. brute force, as the wizards' spells are pitted against the Xenomorphs' physical strength and reproductive abilities.

The theme of Tonks' love life is quite common. Whether it's her relationship with Remus Lupin or other potential partners, it's a big draw for readers. Also, her friendship with other characters, like Hermione or Ginny, is often explored. For example, fanfictions might show them going on adventures together or helping each other out in difficult situations. Additionally, Tonks' role in the fight against Voldemort is a recurring theme, highlighting her courage and magical skills.

One popular theme is Blaise's family history. Given that his family has a mysterious background in the original series, many fanfictions explore it further, like how his family's past affects his present at Hogwarts.

One popular theme is Neville's growth and development. Writers often explore how he overcomes his insecurities and becomes a powerful wizard. For example, in many fanfictions, Neville masters new spells and gains confidence.

The theme of loyalty is quite common too. We see her loyalty to her family, especially her sister Bellatrix and her husband Lucius. But fanfictions also question where her true loyalties lie, especially when it comes to the Dark Lord. For example, in some stories, she has to choose between her family's safety and her loyalty to Voldemort. And then there's the theme of secrecy. Narcissa is a very secretive character in the original books, and fanfictions often expand on this, with her having all kinds of secrets that could change the course of the wizarding world.

One popular theme is the clash of different worlds. Since Harry Potter is set in a magical, somewhat medieval - ish world and Sonic is from a high - tech, fast - paced world, seeing how they interact and collide is fascinating. For example, Sonic's speed in the corridors of Hogwarts.
