A great plot could be that the little vampire is a huge fan of slasher movies himself. He decides to recreate some of the iconic scenes from those movies in the vampire world. But things go wrong when some of the vampires take it too seriously and start acting like real slashers, causing chaos in the vampire community.
One idea could be the little vampire befriending a human who is also a slasher movie fan. They bond over their differences and similarities, like the vampire's nocturnal nature and the human's love for horror. The vampire could show the human the 'vampire version' of horror, which is their everyday life.
One idea could be exploring the vampire's family history more in - depth. Maybe there are ancient secrets or rivalries within the vampire clan that the main characters could uncover.
Perhaps Rudolph discovers a hidden power within himself that helps him protect his vampire family from a new threat in their town. This could involve a series of challenges where he has to learn to control this power.
Perhaps the fanfiction could explore a friendship between the little vampire and a human who discovers his secret. They could go on adventures together, with the human helping the vampire understand human emotions better, and the vampire using his powers to protect the human from danger.
A really interesting plot could be that Gregory gets lost in the human world during the day. He has to find his way back home while avoiding being discovered by too many humans. He could meet a kind old lady who helps him without really knowing what he is, and through this encounter, he learns more about human kindness.
Maybe the OC has a special power or ability that Rudolph needs. For example, the OC can sense when danger is near. They team up to protect Rudolph's vampire family from a group of hunters who have come to town. As they work together, a deeper bond forms between them.
One idea could be a crossover with a popular wizarding world. The little vampire could attend a magic school and have adventures with the wizard students, facing magical creatures together. Another idea is to cross it over with a time - traveling story. The vampire travels through different eras, experiencing different cultures and historical events.
One idea could be to write about the little vampire's first day at a human school. He has to hide his fangs and his love for blood while making friends. It would be full of comical situations like when the cafeteria serves steak and he has to resist the urge to pounce on it.
One idea could be that Merlin, as a wizard, is hunted by vampires because his magic is seen as a threat to their existence. But then he discovers that some vampires are not as evil as he thought and they form an uneasy alliance to fight a common enemy, like a dark sorcerer.
Well, you could have a story where a small town is suddenly surrounded by vampires. The townspeople have to quickly learn how to defend themselves. Maybe they start using old - fashioned weapons like stakes and crossbows. And there could be a mystery within the town, like someone is secretly working with the vampires. This adds an element of suspense to the survival aspect.
One idea could be that the vampire bride discovers a hidden power within herself that can change the vampire world. For example, she might be able to walk in the sun without harm, which is unheard of among vampires. This new power could make her a target for some vampires who want to use it for their own gain, and a savior for others who are tired of living in the shadows.
