I think Hermione would be the most interesting. She's always full of knowledge and wisdom. When she meets the young Weasleys, she can be really strict about them studying magic properly, but also very kind when teaching them. She could show the young ones how to use magic for good and useful things, like helping around the house magically in a proper way.
One of the young Weasleys could be the most interesting. Let's say Ginny's youngest sibling. They would be full of curiosity and energy. Meeting the Golden Trio would be like a dream come true for them. They could ask all kinds of innocent but really interesting questions, like 'Is it true you fought a basilisk?' or 'Can you really make a Patronus?'. Their fresh perspective on the Trio's adventures could make them the most interesting character in the fanfiction.
Ron could be the most interesting. He has that laid - back yet brave nature. The young Weasleys would probably look up to him a lot. He could tell them funny stories about his time at Hogwarts, especially about the food in the Great Hall. And he could also teach them some basic self - defense spells in a really casual and fun way that only Ron can do.
Well, in such a fanfiction, they might have all sorts of adventures. Maybe the Golden Trio - Harry, Hermione and Ron - could share their Hogwarts experiences with the young Weasleys. They could teach them some cool spells or tell them stories about fighting Voldemort. It would be a great way to pass on their knowledge and wisdom.
Their relationships could develop in many ways. For starters, Harry might look up to James as a father figure he never really got to know. James, in turn, would be proud of his son. Sirius could become like an older brother to all three of the Golden Trio. He'd be protective and also share his wild stories with them. Remus would be a great source of wisdom for them, and Hermione would especially appreciate his knowledge. Ron might be a bit in awe of the Marauders at first, but soon they'd all be joking around like old friends. The relationships would likely be based on mutual respect for their different skills and the common goal of making the wizarding world a better place.
The Penguin could be the most interesting. He's got his devious mind and his connections in the criminal underworld. His umbrellas and other gadgets add a unique touch to his criminal activities. He could be the mastermind behind the Terrible Trio's plans, using his wits to outsmart Batman.
Well, it could be a total chaos. The Golden Trio from Harry Potter are used to magic in a very different way than the Winchesters deal with the supernatural. Maybe they'd start comparing their magical tools. Harry could show off his wand while Sam and Dean might be intrigued by it, or they could teach the Trio a thing or two about hunting demons.
In fanfiction, if the Marauders meet the Golden Trio, there could be a lot of chaos at first. The Marauders were known for their pranks and mischief, while the Golden Trio is more focused on fighting against Voldemort. But they might also find common ground. For example, James Potter could bond with Harry over their shared experiences as Gryffindors and leaders in their own ways. Sirius might take a liking to Hermione for her intelligence and bravery, seeing a bit of himself in her willingness to break the rules for what's right. Remus could share his knowledge of the wizarding world with Ron, who is always eager to learn more about magic outside of what he already knows. Overall, it would be an interesting mix of different personalities and generations.
Definitely Thor. His god - like powers and his Asgardian charm are really fascinating. I'd love to hear his stories about Asgard and his adventures in the nine realms.
Spiderman and Black Widow would also have a great interaction. Black Widow could teach Spiderman some espionage and stealth skills, while Spiderman's quick - wittedness and agility would impress her. They could team up for a mission that requires both combat and sneaking around.
Batman, for sure. He has such a complex relationship with the Justice League already. Meeting his family in this context would add another layer to his character. He's the bridge between the two groups.
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.
I think Naruto and the whole Robinson family would have interesting interactions. With Wilbur, Naruto could share stories about his adventures in the ninja world, and Wilbur could tell Naruto about all the time - traveling escapades. Then there's Mrs. Robinson, who could be like a mother figure to Naruto for a while. She might try to get him to eat more proper meals compared to his ramen - only diet. And Mr. Robinson could show Naruto some of his engineering feats, which Naruto would find really cool.
