Well, a mysterious figure who knew about the plot to shoot Lincoln but was too late to stop it could be a main character. This person could then try to piece together the conspiracy and bring the culprits to justice. Another option is a slave who had just been freed by Lincoln's Emancipation Proclamation. The shooting of Lincoln could be a huge blow to their new - found hope, and they could be a main character as they struggle with the implications and try to keep Lincoln's vision alive. And a female spy who was secretly working for Lincoln and was on the verge of uncovering a plot against him when the shooting happened could also be a main character.
The shooter could be a main character. We could explore their motives, their background, and what led them to commit such a heinous act. For example, if the shooter was a disgruntled former soldier who felt Lincoln had wronged him in some way. Another character could be Lincoln's wife. We could see her reaction, her grief, and how she copes with the situation. Or perhaps a doctor who tries desperately to save Lincoln's life could be a main character, showing the medical challenges and the hope against all odds.
One possible main character could be Lincoln's bodyguard. He might feel guilty for not being able to prevent the shooting and then embark on a journey to find the real masterminds behind it. Another could be a journalist who was there at the time of the shooting. They would document the events, interview witnesses, and try to uncover the truth. Also, a young boy who witnessed the shooting could be a main character. His innocence contrasted with the horror of the event could create an interesting dynamic in the fanfiction.
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.
There could be a new character in the fanfiction, like a bully who targets Lincoln just because he seems like an easy target and ends up hurting him.
It could be Chandler. He's always been a bit of a bully in the Loud House universe. With Lincoln having powers, Chandler might become jealous and try to find a way to take those powers away or use them for his own bad purposes.
It could be the shooter. Maybe the shooter has a change of heart after shooting the raven and tries to make amends. He could then become the central figure as he embarks on a journey to save the raven's life.
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.
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.
One possibility is that Lincoln could get super strength. He might use this power to protect his family from various threats in Royal Woods. For example, he could stop a runaway car that was about to hit his sisters.
Perhaps the fanfiction focuses on how Lincoln gets braces and it changes his appearance. His crush could either like the new look or be put off by it at first. He then has to deal with his feelings of insecurity while also trying to show that he's still the same Lincoln, braces or not. For example, he might still be the one to come up with great plans for family outings or helping his siblings with their problems.
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.
Jealousy could be a reason. Maybe Lincoln got something they wanted, like a new game or a special privilege, and they're trying to get him in trouble out of spite.
