The main characters would be Teddy Lupin and the Marauders, but it's possible that Dumbledore could also make an appearance. Since he was headmaster during the Marauders' time at Hogwarts and is always aware of what's going on in the wizarding world. He might play a role in guiding Teddy or in mediating between Teddy and the Marauders, especially if there are any conflicts or misunderstandings. And of course, there could be other minor characters from the Marauders' era, like some of their fellow Gryffindors or teachers at Hogwarts.
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.
Well, it could be about Teddy Lupin traveling back in time and meeting his father's friends, the Marauders. Maybe he gets to experience their pranks first - hand and learns some new magical tricks from 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.
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.
It could be a rogue Death Eater who escaped justice and is now seeking revenge on the Order and anyone related to them. So, Teddy, being Lupin's son, would be a target.
There could also be some minor characters from the Marauders' era that might become more prominent. For example, Lily Evans, Harry's mother. Her relationship with James and how she might interact with Harry in this strange time - traveling or spirit - meeting scenario could be really interesting. And then there are the Hogwarts professors from both eras that could be involved, like Professor McGonagall, who could either be a guiding force or be a bit skeptical of Harry's new interactions.
Perhaps the Marauders are summoned by some dark force in Teddy's time. Teddy, having heard of their adventures, helps them figure out what's going on. They teach Teddy some of their old - fashioned spells and tricks, while Teddy shows them new ways of magic. Together, they face the dark force and emerge victorious, with the Marauders having to find their way back to their own time.
It could be a dark wizard who is trying to prevent Teddy from meeting his father. This wizard might be afraid that Teddy will gain some powerful knowledge or magic from his father that could be used against him.
James Potter could be a fascinating character in this fanfiction. He was the leader of the Marauders and his presence would be quite impactful. Meeting Teddy, he would be full of pride to see the son of his friend. He could share his experiences of being a young wizard and his dreams for the future of the wizarding world. He might also be a bit overprotective, given his friendship with Remus Lupin.
There could also be other supporting characters. For instance, some of Harry's friends from Hogwarts like Ron and Hermione might make an appearance. They could be skeptical of Teddy at first or be involved in the adventures that Harry and Teddy go on. Also, Teddy's family or friends might be mentioned or even play a small part in the story, which could add more depth to his character.
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.
