The main character is James. Regarding the Evans, there could be a character like Mr. Evans who is a strict but fair father figure. And then there might be a female Evans, perhaps named Lily, who has a special connection with James. They could start as friends and then their relationship could develop into something more meaningful as the fanfiction progresses.
One common theme is friendship. Often, James and Mr Evans start off as strangers and gradually form a strong bond of friendship. For example, they might help each other through difficult times or share common interests.
A possible plotline could be that James is a new student and he meets the Evans family. One of the Evans siblings is having trouble at school, and James decides to help. As they work together, they start to form strong friendships. There could be obstacles like bullies or difficult teachers along the way, but through their combined efforts, they overcome them and grow closer as a group.
The main characters are James Potter and Lily Evans, of course. James is a popular and sometimes mischievous wizard at Hogwarts. He's known for his talent in Quidditch and his group of friends. Lily, on the other hand, is a bright and intelligent witch. She's kind - hearted but also has a strong will, which makes her very interesting.
One great 'James meets Mr Evans' fanfiction is 'The Unexpected Encounter'. It has a really interesting plot where James and Mr Evans meet in a very unusual setting, like an old, abandoned library. The author does a wonderful job of describing their initial shock and then the slow development of their relationship.
Maybe Mr Evans is a wizard who has been living in seclusion for a long time. He comes out of his hiding when he hears about the Marauders and their adventures. He could be an old wizard with a lot of knowledge and skills that the Marauders could benefit from, or he could be someone who needs the Marauders' help to solve a personal problem.
Well, Petunia can be really well - written. If the author delves into her insecurities and jealousy towards Lily, and then shows how she reacts to James, it can create a very complex and interesting character. For example, a good fanfiction might show Petunia's internal struggle when she sees James' charm and popularity.
Petunia could be an important character. She might be grudgingly attending the wedding, still having mixed feelings about Lily's magical world. Her presence could add some tension as she struggles to fit in. And then there's Dumbledore. He could make an appearance and give some wise words of advice to the couple, perhaps about the future challenges they might face together.
Obviously, the Marauders which include James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew. And then there are the Evans family members. Most likely Lily Evans, who is quite important as she has her own story arc and connection to the Marauders, especially James. There might also be other Evans siblings or family members depending on how the fanfiction is written.
It could be a dark wizard who wants to prevent Ginny from meeting James and Lily. Maybe this wizard has some grudge against the Potter family and knows that if Ginny meets them and learns something important, it will foil his evil plans.
Well, obviously Harry Potter is one of the main characters. And then there are members of the Evans family. Lily Evans, who is Harry's mother, is a key figure. Her parents, who are part of the Evans family, would also be important characters. There might also be other extended family members that the fanfiction writer creates to add more depth to the story.
