A fanfic could be set around a holiday. For example, during Christmas, the Loud kids all want different things for the holiday, and they have to find a way to compromise and make it a great Christmas for everyone. There could be mishaps like a ruined Christmas dinner or a lost present, but in the end, they come together and have a wonderful celebration.
Another plot idea could be a story where the Loud family takes in a stray animal. The kids all have different ideas on how to take care of it, and they learn about responsibility and compassion. They might also have to deal with the animal getting into trouble around the house or trying to find its real home. This would be a heartwarming and family - focused fanfic.
Friendship is a big theme too. Fanfictions might show how the Loud kids make new friends at a summer camp or how they help a friend in need. There are also stories about the kids' rivalries, like when two of them compete for the lead role in a school play. These rivalries can add drama and humor to the story.
Another plot could involve a love triangle among the Loud siblings' friends. They all end up at the Loud House often, and the love triangle causes some tension. But through various events at the house, like parties or family outings, they start to understand each other better and resolve their differences in a really sweet way.
One idea could be that the Loud family members gain superpowers similar to the Avengers and have to team up to save Royal Woods from an alien invasion. For example, Lincoln could be like Captain America, leading the group with his strategic mind.
One idea could be that Naruto somehow ends up in the Loud House world. Maybe he's on a mission and a strange jutsu goes wrong, transporting him there. He could use his ninja skills to help the Loud siblings out with their daily problems, like getting rid of a bully at school using his shadow clone jutsu.
One idea could be a time - travel plot where a character from the Loud House goes back in time and has to deal with changes in the family's history. Another could be a 'what if' scenario, like what if Lincoln had a different set of sisters. Maybe he could have all older sisters and the story could explore how that dynamic changes things.
A cool plot for 'the loud house crossover fanfiction' might involve a crossover with 'My Little Pony'. The ponies could come to Royal Woods, and the Loud sisters could be fascinated by their magic and cuteness. Lincoln might have to figure out how to get the ponies back to Equestria while also dealing with his sisters' excitement. Or perhaps the Loud family travels to Equestria and has to adapt to a world ruled by ponies.
One idea could be that Lincoln Loud discovers a rare and powerful Pokemon in Royal Woods. He then has to keep it a secret from his sisters while training it. Another could be the Loud sisters each getting a Pokemon that reflects their personalities. For example, Lola might get a Jigglypuff because it's cute and girly.
There could be fanfics that create unique scenarios for the Loud House family. Maybe a time - travel adventure where they go back in time and meet their ancestors. This type of fanfic often brings out a lot of creativity and interesting character developments.
One interesting 'Loud House No Such Luck' fanfic could be one that explores Lincoln's feelings in more depth. Maybe it shows his inner thoughts during the events of the episode that we didn't get to see in the show. Another could be a fanfic that changes the outcome of the episode, like having his family realize they were wrong to be so superstitious about him.
One interesting Loud House NSL fanfic could be one that focuses on the siblings' adventures during a school project. It might show how they cooperate and overcome difficulties together. Another could be a fanfic centered around a new neighbor moving in and how the Loud family interacts with them in the NSL (presumably a specific setting or concept in the Loud House universe).
