The main characters are obviously Fred and George from the Weasley family, and the Marauders which include James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew.
In this fanfiction, Fred and George might get into all sorts of mischief with the Marauders. They could learn some new pranking tricks from James and Sirius. Maybe they'd team up to play a huge prank on Snape, just like the Marauders used to do.
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.
The main characters would be the Marauders, which include James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew. And of course, Tonks is also a main character in this fanfiction.
Well, Harry is the central figure in this fanfiction as he takes on the role of the adoptive father. Fred and George are the main recipients of his care. But we can't forget about the Weasley family as a whole. Even though Harry is adopting Fred and George, the rest of the Weasleys might still play important roles. They could be visiting, giving advice, or just being part of the big family that the story is set in.
Maybe they overhear a secret conversation between teachers or magical creatures that give them clues. Or it could be that they discover a hidden room filled with evidence about the Marauders.
Obviously, the Marauders themselves - James Potter, Sirius Black, Remus Lupin and Peter Pettigrew would be the main characters. They are the ones 'meeting' the future after all.
The marauders are the central figures from the past. James Potter could be a fun - loving grandfather, Sirius Black the cool and rebellious one. Remus Lupin would be the wise and kind grandfather. Their grandchildren could be a diverse bunch. There might be a Potter grandchild who is a bit of a troublemaker like James was. A Black grandchild who is very proud of their family heritage. And perhaps a Lupin descendant who is very studious and wants to learn all about Remus's life. Peter's grandchild might be a character who is trying to find their place in the family after Peter's betrayal.
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.
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.
The marauders are central, of course. James Potter with his charm, Sirius' rebellious nature, Remus' wisdom. From the next generation, Hugo Weasley could be a main character too. He might be in awe of the marauders at first, but then they all start to work together. Maybe they're all trying to prevent a new dark wizard from rising, and the combination of the marauders' experience and the next generation's fresh ideas is what it takes to succeed.
