Severus Snape could be a key character as well. Since he has a long - standing feud with the Marauders, his interactions with them during their planning and execution of plans would create a lot of tension and drama in the fanfic.
Lily Evans could also be a main character. She might be involved in some of their plans, either as an ally or as someone they have to convince to go along with their ideas. Her relationship with James Potter could add an interesting dynamic to the story.
Well, it could involve the Marauders getting into some wild adventures at Hogwarts. Maybe they plan a big prank on Snape that goes awry in a really funny way.
A good marauder's plan fanfic usually has a unique plot twist and well-developed characters. It keeps you engaged and guessing.
In addition to the Marauders, some fanfics might also focus on their children or those directly affected by their actions. For instance, Harry Potter himself, as the son of James and Lily. His story is intertwined with that of the Marauders as their actions and sacrifices ultimately led to his survival. And then there are characters like Neville Longbottom, who could also be related to the Marauder - era events in some fanfics.
An ordinary high school student could be the main character. Their ten - year plan might involve getting into a top university, starting a successful business, and falling in love. Throughout the fanfiction, we see how they balance all these aspects of their life.
Hermione and Ron would also be important characters. Hermione might be initially skeptical of Harry's newfound obsession with the Marauders. Ron, on the other hand, might be more easily swayed and join Harry in his attempts to be more like the Marauders.
Obviously, Harry would be one of the main characters since it's his plan that is being set off. Hermione and Ron would most likely be involved too as they are his closest friends and often accompany him in his adventures. There might also be other characters like Dumbledore, if the plan has something to do with Hogwarts or the fight against dark magic, or perhaps some new characters created specifically for this fanfic.
Since I'm not familiar with this particular novel, it's difficult to determine the main characters precisely. However, in addition to the billionaire, there may be antagonists such as rival business moguls who try to thwart his alternate plan. There could also be characters like his personal advisors or friends who either support or question his decisions regarding the plan.
Since I don't know the specific 'the family plan story', I can't say for sure who the main characters are. It could be the parents, children, or perhaps extended family members like grandparents.
I don't have enough information to know exactly who the main characters are. They could be players in the game that the novel is centered around, like a team of athletes or gamers.
It could be the whole family. For instance, if it's a story about a family - run business plan, then all family members who are involved in the business, including the children if they are old enough, would be the main characters. Each one might contribute their own ideas and skills to the plan.
