Well, in some of these fanfictions, there could be a plot where Draco and Harry are sent back in time and meet the Marauders. They might have to work together to solve a mystery that's related to both their times. For example, a dark magic that was sealed in the past is starting to resurface in their present, and only by combining the knowledge of the Marauders' era and their own can they stop it.
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.
One interesting plot could be Harry time - traveling and getting to join the Marauders on one of their pranks at Hogwarts. He might learn some new spells and mischief - making techniques from them.
Another plotline could involve Petunia getting involved in one of the Marauders' adventures by accident. Maybe she stumbles upon them while they are exploring a secret part of Hogwarts and has to work with them to get out of a tricky situation.
Perhaps a plotline where Ginny accidentally travels back in time and actually meets the Marauders. This would lead to a whole series of adventures as she tries to fit in with their group, while also trying not to change the future too much. She might have to help them with some of their pranks against Snape without making things worse between them.
One interesting plot could be the Marauders' adventures during their school days that were not fully explored in the original books. For example, their pranks on other students and how they managed to create the Marauder's Map. Another could be a story where the Marauders interact with Harry in a time - travel scenario, giving him advice and helping him face Voldemort in a different way.
One interesting plot could be Hermione using her advanced knowledge to teach the Marauders about complex magic they hadn't considered before. Maybe she teaches them about time - turning spells in a more in - depth way, leading to some unexpected adventures where they have to use this knowledge carefully.
One interesting plot point is that Draco, being a Slytherin, might try to use the Dursleys for his own gain at first. But as he gets to know them better, he realizes that they are more complex than he thought. Also, the cultural clash between the wizarding world Draco comes from and the Muggle world of the Dursleys can lead to many humorous and thought - provoking situations. For example, Draco's confusion over Muggle appliances and the Dursleys' bewilderment at Draco's magic.
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.
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.
Maybe Harry finds himself in a situation where he has to team up with the Marauders to fight a common enemy that was previously unknown in the original Potter story. This would create a whole new dynamic and show how different generations of Hogwarts students can work together.
