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.
Their relationship might become more light - hearted. They'd have this new and strange thing to bond over. They could start making inside jokes about the fem Harry in the fanfiction. For example, Sirius might tease James about how he would act around a female Harry, which would add a new dynamic to their friendship.
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.
They might be shocked at first. I mean, seeing their own stories being written in a different way by fans would be quite unexpected. Sirius might find it really cool and be eager to read more, while James could be a bit more critical, thinking about how accurate the portrayal is. Remus would probably be more laid - back and just enjoy the different interpretations.
The wizards from Harry Potter would be in awe of Narnia's magical creatures. Harry, for instance, would be fascinated by Aslan. He'd probably see Aslan as a powerful and wise being, much like Dumbledore. On the other hand, the Narnians might be a bit scared of some of the dark magic in the Harry Potter world. For example, the Dementors would be a terrifying sight for them.
They might be very amused. The marauders are known for their sense of humor and the 'A Very Potter Musical' fanfiction is often full of comical and over - the - top elements. So they'd probably have a good laugh at the silly situations and the creative liberties the fanfic takes.
Some popular ones include 'Padfoot Returns'. This fanfic is interesting as it imagines what would happen if Sirius Black came back in a different scenario. Then there's 'Remus Lupin: The Hidden Years' which focuses on Remus and his experiences that are not fully explored in the original books. Also, 'James Potter: The Early Years' gives a great insight into the character of James Potter, his growth, and his relationships within the Marauders group.
Well, it could be some new students who are very much like the original Marauders in terms of their mischievous nature and loyalty to their friends. Maybe a Gryffindor with a great sense of adventure, a Hufflepuff who is unexpectedly brave and loves to get into fun, a Ravenclaw with a brilliant mind for coming up with pranks, and a Slytherin who has a soft spot for his new group of friends.
Dumbledore would likely see it as an interesting development. He would observe Harry closely to see how the mask affects him. He might also try to guide Harry in using the power of the mask for good. Snape would be his usual skeptical self. He'd think that Harry is getting involved in something he doesn't understand and would be secretly keeping an eye on him.
