One common theme is the clash of two different worlds. The wizarding world of Harry Potter with its magic, spells, and Hogwarts, and the world of vampires with their own set of rules about blood, immortality, and night - living. This clash often leads to interesting situations and conflicts in the story.
Another theme is the exploration of power. Combining Harry's magic power with the unique powers of a vampire, such as super strength or mind - control abilities in some vampire lore, can create a very powerful couple. Fanfictions often explore how this new - found power is used, whether for good, to protect the wizarding world, or if it becomes a source of corruption and conflict.
A frequent theme is the breaking of boundaries. In the original story, Harry and Voldemort are on opposite sides of a huge divide. Fanfictions with this plot explore what happens when those boundaries are shattered. Also, there can be a theme of discovery. Harry discovers a new side to Voldemort that no one else has seen, and this leads to their relationship. And of course, there's the theme of transformation, both for Voldemort in terms of his character and for the whole 'Harry Potter' world view as a result of their relationship.
Yes, there are likely to be such fanfictions in the vast world of fan-created content. Fanfiction often explores unique and non - canonical relationships.
A prevalent theme is isolation. Vampires are often seen as outsiders in the magical world of Harry Potter. So, Harry may find himself isolated from his friends and the wizarding community in general. He has to deal with the prejudice and fear that others have towards his vampire - like qualities. This theme adds a lot of emotional depth to the stories. In addition, the theme of redemption can also be found. Harry might try to redeem the image of vampires in the eyes of the wizarding world, or he might seek redemption for actions he takes while under the influence of his vampire side.
Common themes include the struggle between good and evil within the relationship. A female Harry Potter represents good, and Voldemort is the epitome of evil, so seeing how that balance is achieved or disrupted is interesting. Another theme is the impact on the Death Eaters and the Order of the Phoenix. Their reactions and how they adapt to this new situation are often part of the story. Also, the theme of forgiveness can be present, as Harry Potter might have to forgive Voldemort for his past deeds for the relationship to work.
One common theme is redemption. Writers often explore the idea of Harry being the one to redeem Tom Riddle from his path to becoming Voldemort. Another theme is the power of love. In these fanfictions, the love between Harry and Tom is sometimes portrayed as something that can change the entire wizarding world's fate. There's also the theme of alternate realities, where the normal rules of the Harry Potter universe don't apply and such an unlikely relationship can exist.
There probably is. Fanfiction writers love to explore different relationships and scenarios. Since the Harry Potter world has a rich lore and the concept of vampires exists in the wizarding world too, it's not a far - fetched idea for someone to write a story about Harry Potter marrying a female vampire. You can usually find these on fanfiction websites by using relevant search terms.
Another theme is the idea of good vs evil in a new context. Since both universes have their own versions of good and bad, when combined in fanfiction, it creates new scenarios for the characters to face moral dilemmas. For example, a vampire from Rosario Vampire might have to decide whether to follow the more black - and - white moral code of the Harry Potter world when dealing with a dark wizard.
The themes usually include the acceptance of the supernatural. Harry becoming a vampire is a huge supernatural change, and the fanfictions often explore how he and those around him accept or reject this new state. Also, there's the theme of secrecy. Vampires are not exactly welcome in the wizarding world in most of these stories, so Harry has to keep his vampiric nature a secret from some while being open with his harem. And of course, there's the theme of jealousy within the harem as different characters vie for Harry's attention.
One common theme is the struggle between the vampire nature and the magical world's norms. In these fanfictions, characters often have to hide their vampire instincts to fit in at Hogwarts or in the wizarding community.
A major theme is secrecy. Since vampires are often seen as a threat in the wizarding world, Harry has to keep his new nature a secret. This creates a lot of tension as he has to constantly hide who he really is from his friends and teachers. It also ties into the theme of trust, as he has to decide who he can trust with his secret. Some stories might show him being betrayed when his secret gets out, while others might show him finding true friends who accept him despite his vampiric side.
