It could be a vampire hunter. He might move to Royal Woods and start suspecting that there is a vampire in the area, which of course is Lucy. He could be very determined and use all kinds of tricks to try and catch her.
A jealous vampire from a rival vampire family could also be the main antagonist. This vampire could be envious of Lucy's unique place in the Loud family and her ability to live a somewhat normal life among humans. So, he or she tries to disrupt her life and drive her away from her family and friends.
Perhaps an older and more powerful vampire who doesn't like Lucy's modern - day vampire ways. He might see her as a threat to the traditional vampire ways and try to stop her from doing things like going to school or being friends with humans.
Maybe Lucy could find a way to use her vampire abilities to help her siblings in a time of need. For example, when they are facing a mysterious threat in the neighborhood, her vampire powers like super strength or the ability to turn into a bat could come in handy.
Luna could also be a good match. Luna's laid - back and cool personality could contrast well with Lucy's more somber and mysterious vampire self. They could bond over their 'outsider' status in a way, with Luna being the rocker chick and Lucy being a vampire. Maybe they could form a band where Lucy uses her vampire - like charm to draw in the crowds.
A third plot idea is that a group of vampire hunters come to Royal Woods believing there is a vampire in the Loud House. Lucy has to use her wits and any vampire friends she might have made to outsmart the hunters and protect her family. This could involve some really exciting chase scenes and moments of clever deception.
One possible fanfiction could be where Lori, as a vampire, struggles to keep her identity a secret within the Loud House. She might have to deal with her newfound cravings for blood while trying not to alarm her family. Maybe she forms an unexpected alliance with one of her siblings who discovers her secret and helps her find alternative ways to satisfy her thirst without harming anyone.
One common theme is the clash between the normal family life of the Louds and the supernatural world of vampires. For example, the Loud kids still have to go to school and do chores while also dealing with a vampire threat. Another theme is mystery. Usually, there's a mystery about the vampire's origin or their motives in the fanfiction.
One common theme is the idea of understanding. Since Lucy and Lincoln are quite different, a lot of fanfictions focus on how they come to understand each other better. Another theme is the discovery of a special bond that's unique to them, different from their relationships with other siblings.
There might be a new character introduced in the fanfiction as the antagonist. A kid from school who is jealous of Lincoln and Sid's new friendship. This character could spread rumors about them or try to break them apart by causing misunderstandings between them.
Well, in a Loud House Lori vampire fanfiction, the plot might start with Lori being lured into an old, spooky part of town where she gets bitten by a vampire. After that, she has a whole new set of problems. Her siblings start to notice her odd behavior, like being awake all night. She has to deal with her new powers, such as being able to run extremely fast. She could also be in a situation where she has to protect her family from other vampires who see her as a threat because she doesn't want to join their dark ways. This would lead to a series of adventures and challenges for Lori as she tries to balance her two lives.

One common theme is the vampire's struggle to fit into the Loud House family. Since the Loud House has a big family dynamic, it's interesting to see how a vampire character would interact with all the siblings and parents.
