Sirius Black is often really popular. His rebellious nature and his complex backstory make him a very interesting character to explore in this kind of fanfiction. He can be shown having interactions with new characters from the modern Hogwarts era.
Luna Lovegood can be a popular character when she meets the Marauders. Her unique view of the wizarding world and her rather eccentric personality can create some really fun and unexpected interactions with the more rough - and - tumble Marauders. For instance, she might introduce them to some of the strange creatures she believes in, and they might be both amused and intrigued.
Another plot could involve the Marauders getting involved in a mystery that is plaguing Hogwarts in the present day. They use their old - school pranking skills and knowledge of the castle's secrets to solve it. They might have to team up with some of the current Gryffindor students who remind them of themselves when they were young.
Well, the main ones are Draco Malfoy and Harry Potter. Draco, who has his own journey of redemption in some of these fanfics. Harry, who is always the key figure in any story related to Hogwarts. And then there are the Marauders. James, the confident and sometimes arrogant Gryffindor, Sirius, the rebellious and loyal friend, Remus, the calm and intelligent werewolf, and Peter, who adds an element of mystery and betrayal.
Well, obviously Petunia is one of the main characters. She is Lily's sister and has a complex relationship with the wizarding world. Then there are the Marauders - James Potter, Sirius Black, Remus Lupin and Peter Pettigrew. Each of them has their own distinct personality. James is the confident and sometimes arrogant one. Sirius is the rebellious and charming one. Remus is the more reserved and intelligent one, and Peter is the rather meek and follower - type among them.
Well, obviously Harry Potter is one of the main characters. And then there are the Marauders: James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew. They are central to the story as it's about Harry meeting them.
Obviously, Ginny Weasley is one of the main characters. She's a strong - willed and brave witch. The Marauders, which include James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew, are also likely to be main characters. They are known for their mischief - making and loyalty to each other. Dumbledore might also make an appearance as he was around during the Marauders' time and would surely have some role to play if Ginny is interacting with that era.
It could be Harry Potter's descendants. They might inherit his courage and magical abilities and be the main characters who navigate the encounter between Hogwarts and the future.
In addition to Harry and the Dursleys, there could be some Hogwarts professors involved. For example, Professor Dumbledore might play a role. He could be the one who arranges for some sort of exchange or interaction between Hogwarts and the Dursleys. Also, Hermione and Ron could be main characters if they accompany Harry to meet the Dursleys or are involved in the events that bring Hogwarts to the Dursleys' doorstep.
Well, aside from Teddy and the Marauders, there could be other characters as well. Maybe some of Teddy's friends or classmates from his own time who are somehow involved in his journey to meet the Marauders. For example, if Teddy discovers a time - traveling spell in the library with the help of a studious friend. But the core characters would still be Teddy Lupin and the Marauders. Teddy is the link between the present and the past in this story, and the Marauders are the ones with all the stories and experiences from their time at Hogwarts.
Hermione herself is always interesting. She has her intelligence, determination, and strong sense of justice. When she meets the Marauders, her reactions to their pranks and their more carefree attitudes would be great to explore. Also, Sirius Black. He has his own complex backstory, and seeing how he interacts with Hermione, a girl from the future, could be really engaging. He might see a bit of himself in her rebellious side.
Obviously, Albus Potter and the Marauders - James Potter, Sirius Black, Remus Lupin and Peter Pettigrew. There might also be some other characters like Albus's friends or professors who could be involved in the story.
