Perhaps in this fanfiction, Lincoln is kidnapped by an alien who is fascinated by human behavior. The alien takes Lincoln to their spaceship. Lincoln is initially scared but then starts to learn about the alien's culture. His sisters, on Earth, figure out something is wrong and start looking for clues. Eventually, they manage to communicate with the alien and get Lincoln back.
It could be an angry neighbor who has always been annoyed by the Loud family's chaos. They see Lincoln as the main troublemaker (even if he isn't) and decide to kidnap him to teach the family a lesson.
Maybe it's a new villain in Royal Woods. This person could be jealous of Lincoln's leadership skills within his friend group. So, they kidnap him to try and undermine his confidence and make his friends turn against him. They believe that without Lincoln, the group will fall apart and they can take over as the new 'leader' in the neighborhood.
A possible plot could be that Lincoln is kidnapped by a mysterious figure who has a vendetta against the Loud family. The kidnapper takes Lincoln to a remote location. Lincoln, being the brave character he is, tries to figure out the kidnapper's motives while also looking for an opportunity to escape. Meanwhile, his sisters and parents are following every lead they can find, from Lincoln's friends to any strange activity in town. The fanfiction could build up the tension as Lincoln tries to outwit the kidnapper and his family races against time to find him.
One great Loud House Lincoln fanfiction is 'Lincoln's New Adventure'. It takes Lincoln on a journey outside of Royal Woods where he meets new friends and has to face some unique challenges. It's really exciting as it shows a different side of Lincoln's character.
There could be many interesting fanfictions about Jordan and Lincoln in the context of Loud House for girls. Maybe it could be a story where Jordan and Lincoln team up to solve a mystery in the Loud House. For example, they might be trying to figure out why strange things are happening around the house, like objects moving on their own or mysterious noises at night.
One idea could be a story where Lincoln and Lola have to team up for a school project. At first, they bicker as usual because of their differences. But as they work together, they start to understand each other better. For example, Lincoln realizes that Lola is not just a pageant - obsessed girl, and Lola sees that Lincoln has his own insecurities and strengths.
One common theme is family dynamics. Lincoln often snaps due to the chaos in his large family, like dealing with his sisters' different personalities and the constant noise at home.
One possible fanfiction could be that Lincoln constantly has bad luck in his attempts to get some alone time in the house. For example, every time he plans to have a quiet reading session in his favorite corner, one of his sisters accidentally spills something on him or makes a lot of noise right there. It could also be that his bad luck extends to school, where he always seems to be the one picked on by the teacher for things that are not his fault, like when his classmates play pranks and he gets blamed in the Loud House Lincoln - bad luck scenario.
He could get grounded for getting bad grades at school. Maybe he didn't study enough for a big test and his parents decided that grounding him would be a good way to make him take his studies more seriously.
