One interesting plot twist is when the magic from Harry Potter's world starts to affect the vampires in unexpected ways in the fanfiction. For example, a spell might make vampires temporarily lose their vampiric abilities, which forces them to rely on the wizards for protection. This turns the typical power dynamics on its head and creates a whole new set of storylines.
A really cool plot twist can be when a character from one series has a hidden identity that links them to the other series. For instance, a seemingly ordinary witch from Harry Potter might actually be a vampire - witch hybrid from a long - forgotten Vampire Diaries bloodline. This revelation then leads to a whole exploration of her powers and her place in both worlds, causing all kinds of chaos and new alliances in the fanfiction.
In some fanfics, a plot twist could be that a vampire from Vampire Diaries turns out to be a long - lost relative of a Hogwarts student. This completely changes the dynamics as the student has to deal with their newfound family connection and the fact that they're a vampire.
Another interesting aspect is how the different worlds' rules are bent or combined. For instance, the concept of a Horcrux in 'Harry Potter' and the way vampires can be killed in 'Vampire Diaries'. In some fanfictions, these two ideas are merged. Maybe a vampire tries to use a Horcrux - like mechanism to avoid being killed, or a wizard has to figure out how to destroy a vampire in a way similar to destroying a Horcrux. This creates a whole new set of challenges and mysteries for the characters to solve.
In some fanfics, a plot twist could be that a demigod turns into a vampire. This completely changes the dynamic as they now have to deal with their new vampiric nature while still having their demigod powers. It's a really unique take on the crossover.
A really interesting plot twist is when a character from Arrow gets turned into a vampire in some fanfictions. For example, in 'The Dark Transformation', Felicity Smoak gets bitten by a vampire and has to deal with her newfound vampiric nature while still trying to help Team Arrow. It completely changes her character dynamics and adds a whole new layer of complexity to the story.
A really interesting plot twist could be if Negan turns out to be a long - lost relative of one of the main Harry Potter characters. It would completely change the way he interacts with the wizarding world and the characters' perception of him.
Well, in some fanfics, like 'The Dark Arts of the Wasteland', there's a plot twist where the Death Eaters from the Harry Potter world are somehow related to the Enclave in Fallout. It turns out that they have a secret alliance and are trying to control both the magical and post - apocalyptic worlds. This was really unexpected as it combines two very different evil forces.
In some fanfics, a plot twist could be that Jacob is actually related to one of the wizarding families in Harry Potter, which changes the whole dynamic of their relationship. It adds a layer of mystery and family drama to the story.
Another interesting aspect is the exploration of new relationships. Imagine Harry Potter being friends with Elena Gilbert. Fanfics can develop relationships that were never possible in the original stories. This can lead to some really heart - warming or heart - breaking moments depending on how the author writes it. It also gives a chance to explore different character arcs for the beloved characters from both series.
One interesting plot twist could be when Caesar turns out to be a long - lost wizard. This completely changes the dynamic as he then has to learn about his magical heritage while also dealing with the existing Harry Potter world's problems.
In some 'Harry Potter Sith fanfiction', a plot twist could be that a seemingly good character is actually being influenced by Sith powers all along. For example, a teacher at Hogwarts who is secretly using Sith mind - control techniques on students to further their own dark agenda.
In some fanfics, a plot twist could be that a character from The Originals turns out to be related to a major Harry Potter character. For example, it might be revealed that a vampire has a long - lost wizard relative in the Potterverse. It completely changes the dynamics of how the two worlds interact.
