Well, Harry Potter is the main character who travels back in time to the Marauders era. James Potter is a significant character as Harry's father. Sirius Black, with his charm and wild nature, is an important part of the story. Remus Lupin, the intelligent and kind werewolf, is another mainstay. Peter Pettigrew, though not always a likable character, is also part of the main cast. And there could be other characters like Severus Snape in some fanfics, as his relationship with Lily and the Marauders was complex and could be explored in the context of Harry being in that era.
I really like 'The Marauders' by an unknown author. It focuses on their adventures and how they formed their tight - knit group. It has some really exciting plot twists, like how they dealt with certain dark magic threats in their school days. It's a fun read that keeps you on the edge of your seat.
Remus might be a bit more reserved. He'd approach the fanfics with caution, but he'd also be touched by the stories that explored his struggle with being a werewolf in more detail. He might find comfort in knowing that fans understood his inner turmoil to some extent.
Another theme is the fight against dark magic. During the Marauders era, Voldemort was rising to power, so fanfics may show how the Marauders and their allies were involved in the early battles against the Death Eaters. There's also the theme of growing up and facing the responsibilities that come with being a wizard in a dangerous time.
One great 'Harry goes to the marauders era' fanfic is 'Time Traveler'. It has an interesting plot where Harry has to navigate the challenges of the marauders' time while trying not to change too much of the future. Another is 'Marauder's Mayhem' which focuses on Harry's interactions with the marauders and how he fits into their group dynamic. There's also 'Back in Time with Harry' which shows a more emotional side of Harry as he meets his parents' generation.
They would probably be very curious at first. But as they read more, they might get annoyed if the fanfiction doesn't stay true to their essence. For instance, if a fanfiction portrays Sirius as a coward, which is completely against his real character, they would be offended. However, if they find a well - written fanfiction that respects their characters, they might enjoy it.
One great 'Harry in Marauders era fanfic' is 'Time-Turner Tales'. It delves into how Harry's presence in the Marauders' time changes the dynamics. Another is 'Harry Among the Marauders' which focuses on his relationships with the group. And 'Marauder - Harry Connection' shows some unique adventures of Harry with the Marauders.
It could potentially change their relationships. If they read a fanfiction that explored deeper emotional aspects of their friendships, it might make them more aware of their feelings for each other. They might become more open and communicative within their group. For example, Sirius and Remus might have a heart - to - heart about their true feelings for each other if a fanfiction made them realize something they hadn't before.
One interesting plotline could be Harry trying to prevent the death of his parents. He might use his knowledge from the future to change certain events. For example, he could try to stop Voldemort's rise to power earlier in the Marauders' time.
