I think Lori could be paired well with Lincoln. Since she's the eldest sister, she could be mentoring Lincoln in something, like how to deal with high school or relationships. And then there's Stella. If paired with Lincoln, they could have a story about exploring a new part of town and finding some kind of hidden treasure or secret place that only they know about.
Leni could be an interesting character to pair with female Lincoln. Since Leni has her own unique view of the world, they could have some really comical and heartwarming interactions. Also, Ronnie Anne could be paired with her. They might bond over things like their shared experiences in school and their different family dynamics.
Lincoln and Naruto would be a great pair. They both have leadership qualities and a sense of responsibility. Lincoln as the only boy in a large family often has to take charge in certain situations, and Naruto is the leader of his ninja team. They could learn from each other's experiences.
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.
There might also be some original characters created specifically for the fanfiction. These could be other humans who know about Lincoln's secret or other supernatural beings that are related to the vampire lore in the story.
Well, of course, Lincoln Loud would be one of the main characters. He's the central figure in the Loud family, so it makes sense for him to be the focus in this fanfiction. His sisters might also be involved. For example, Lola could be competing with Lincoln in a lemon - themed beauty pageant, adding some sibling rivalry to the story.
His sisters could be main characters. For instance, Lori might give him some advice on how to deal with the braces since she's the eldest and has more experience. Or Leni could be there to offer some fashion tips to make him feel better about his new look with the braces.
Well, his sisters from 'The Loud House' could make an appearance in some way. Maybe they get transported to the Pokemon world too, or they are just part of Lincoln's memories that he draws strength from. In the Pokemon world, he could meet classic Pokemon characters like Ash, Misty, and Brock. They could help him on his journey or be rivals in some Pokemon battles.
A popular one is 'Lincoln Loud and the Mysterious Reader'. In this fanfiction, there's an element of mystery as the reader character has a secret that Lincoln helps uncover. It's full of suspense and at the same time, the relationship between them develops in a really engaging way.
Well, obviously Lincoln Loud is one of the main characters. And then there would be the members of the harem, which could include some of the female characters from the original 'Loud House' series. For example, Lori, Leni, and Luna could potentially be part of the harem in the fanfiction.
Maybe some new kids in the neighborhood who are trying to establish their dominance and pick on Lincoln as an easy target. They might not know much about him or his family, but just see him as someone they can bully.
