The main character from the original source material is usually quite popular. They often become the center of various fan - created storylines. Another character might be their best friend, who plays a crucial role in either helping them get over their past love or in unknowingly bringing them back together.
Sometimes it's a vampire themselves trying to get over another vampire. Maybe a young vampire who was turned by a more powerful one and had feelings for them, but then realizes they need to break free. They could be struggling with their loyalty to their sire and their own desire for independence and a new life without that emotional attachment.
In some fanfiction, there could be a storyline where the characters are forced to work together on a community project. They initially resist but as they spend more time together, old feelings resurface. This creates a lot of tension and drama as they struggle between their past and present emotions. It's a great way to explore the characters' growth and their relationship in a new light.
There might be a fanfiction where the character uses magic to erase their memories of the vampire they're getting over. But as they start to build a new life, things keep triggering small memories, and they have to fight to stay away from the vampire. It could be a story full of suspense and internal struggle as they battle their own heart and the pull of the vampire world.
Fiona is also a top choice. Her relationship with Shreck in the movies gives a lot of material for crossovers. Fanfiction writers might explore how she and Shreck interact in different universes or scenarios, like in a world where they are not in the same fairytale but a different, more modern world.
Ben 10 is a favorite for many. As I said before, the clash between Johnny's human - centered confidence and Ben's alien - powered abilities is exciting. Also, characters like Dexter from Dexter's Laboratory are often used. The scientific genius of Dexter and the not - so - smart Johnny can lead to hilarious and complex stories. Courage the Cowardly Dog is also a great choice as the spooky and strange world Courage lives in can be a great backdrop for Johnny's adventures.
Harry Potter himself is still very popular. Since it's a 'do over', readers are interested in seeing how he might change things with his knowledge from the first time around. He could be more confident or make different choices in relationships, like with his friends or romantic interests.
Thor is often crossed over with the Hulk. They already have a history in the official comics with their epic battles. In fanfiction, it could be about them teaming up more often or having to face a threat that only their combined powers can defeat, like a powerful cosmic entity.
Jon Snow is often still a very popular character. His story of being a bastard and his true heritage make him an interesting figure. In fanfiction, he might get to explore his role as a potential king or leader in different ways than in the original series.
Definitely Iron Man. Their relationship in the official Marvel movies has already been very popular, so in fanfiction, writers love to explore more of their interactions. Iron Man can provide high - tech support to Spider - Man, and they can have some really smart and witty conversations.
Sherlock Holmes is also quite popular. Holmes' deductive skills against Darth Vader's power in the Force would make for an exciting story. Holmes could be trying to figure out Vader's motives and secrets, while Vader might see Holmes as a nuisance or a potential ally depending on the situation.
