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.
Perhaps the fanfiction involves Sid being a new neighbor in the Loud House neighborhood. She meets Lincoln, and they start a club together. They face challenges like getting other kids to join and dealing with a bully who wants to shut down their club. This could lead to a lot of fun adventures and them learning about friendship along the way.
In the fanfiction, Lincoln and Sid could get into some comical situations. For example, they could accidentally cause chaos while trying to cook a meal for the Loud family. Or perhaps they team up to prank Lincoln's sisters, but the prank backfires in a hilarious way. Their meeting could also lead to a deeper understanding between them, where they learn about each other's family dynamics and how different yet similar they are.
One way could be that Sid hears about Lincoln through mutual friends in the Loud House universe. Maybe they both like the same hobby, like collecting comic books. So, Sid could go to a comic book convention where Lincoln is also present, and that's how they meet.
They could talk about their families. Lincoln has a large and unique family, and Sid could share stories about her own family. For example, Lincoln might tell Sid about his sisters' crazy antics, and Sid could talk about her siblings if she has any.
Maybe Sid has a hidden talent that he reveals to Lincoln. For instance, he could be a master of martial arts or a brilliant inventor. But there's a catch - his talent is being hunted by some bad guys in the Loud House world. Lincoln then has to help Sid keep his talent a secret while also using it to save the day. This would add a lot of action and mystery to 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.
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.
Maybe a time - traveling collector. This character travels through different times collecting rare items or memories. When Lincoln enters a particular time period, the collector sees Lincoln's unique family situation as a valuable item to collect and tries to keep him trapped in that time, away from his own family.
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.
His siblings could be responsible. They are always getting into crazy situations together, and maybe one of their pranks or games goes too far and accidentally hurts Lincoln.
