If Harry and Ginny meet the Marauders in fanfiction, it would be a moment full of emotions. Harry has always longed to know more about his father, and this would be his chance. The Marauders, on seeing Harry, might see a lot of James in him. Ginny would add a different dynamic to the group. She could be the voice of reason at times. Together, they could create new memories. For example, they might team up to play a prank on Snape's memory or something, which would be both funny and a way to pay homage to the Marauders' legacy.
One great 'marauders meet harry fanfiction' is 'The Marauders' Era Rewritten'. In this story, Harry is sent back in time and gets to interact with the Marauders in a really unique way. It shows how their personalities clash and mesh with Harry's.
The main characters are Harry Potter and the Marauders. Harry, as the protagonist of the main series, is the focus when it comes to the encounter. The Marauders, consisting of James, Sirius, Remus, and Peter, each have their own personalities and stories. James was Harry's father, so his connection is deep. Sirius was Harry's godfather, a brave and rebellious character. Remus was the wise werewolf friend, and Peter, though a traitor, has his own part to play in this fan - made story.
In such a fanfiction, one possibility is that the Marauders get to see how much Harry resembles James. They might be amazed by his courage which is similar to what they had in their Hogwarts days. Maybe they would offer him some unique magical advice based on their own wild adventures at school.
One possible plot could be that the Marauders, in some magical time - travel or alternate reality scenario, get to meet baby Harry. They might be overjoyed to see him and immediately vow to protect him. Sirius could be especially attached, given his future relationship with Harry. They might also play with baby Harry, making him giggle with their magic tricks.
The main characters are clearly the Marauders - James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew. And of course, baby Harry Potter. The Marauders are important as they were Harry's father's friends, and their presence around baby Harry would create an interesting dynamic.
