I think Hermione would be really interesting in a crossover. She's so intelligent and curious. If she were in the Naruto world, she'd be eager to learn about chakra and all the ninja techniques. She might even find a way to combine magic and chakra in some unique way.
Definitely Naruto and Hermione. Naruto's brash and straightforward nature would contrast with Hermione's studious and rule - following personality. They could have some really interesting debates. For example, Naruto might not understand Hermione's obsession with books and Hermione might be baffled by Naruto's lack of formal education but amazing combat skills.
Jacob and Ron would be a great pairing. Jacob's easy - going nature and loyalty as a werewolf could mesh well with Ron's sense of humor and his own loyalty to his friends. They could get into all sorts of misadventures, like trying to combine wizard food with werewolf hunting techniques or something equally absurd.
Harry and Naruto would be an obvious and very interesting pairing. They are both the main heroes in their respective stories, so seeing them interact, share their experiences, and learn from each other would be great. Hermione and Sakura could also be a fascinating pair. Both are intelligent and strong - willed female characters. Hermione could teach Sakura about complex magic theories, while Sakura could show Hermione some of her medical ninjutsu skills.
Hermione would be really interesting. She could bring her intelligence and knowledge of magic to the iCarly crew. Imagine her helping Freddie with his tech projects using magic, or teaching Carly and Sam some basic spells. It would be a great contrast between the magical and Muggle worlds.
It could be Aquaman. He is so different from the wizards in the Harry Potter universe. His fish - like abilities and his role as a king would make for some great interactions with the Hogwarts students and professors. He could teach them about the ocean and its secrets, while also being amazed by the magic of wands and potions.
Percy would be really interesting. His ability to control water and his laid - back yet brave personality would contrast well with the more formal wizarding world. He could make some really funny and unexpected interactions with the Hogwarts students and teachers.
I think Michael Corvin could be an interesting crossover character. He's a hybrid in the Underworld series, which means he has a unique set of abilities. In the Harry Potter world, he could be seen as a strange new kind of magical being. He might be able to help the wizards understand different types of magic that are more physical and instinct - based like his own. Also, his journey of self - discovery in the Underworld could be paralleled in the wizarding world as he tries to find his place among the wizards and witches.
It's hard to say. Naruto has his huge chakra reserves and powerful jutsu. But Harry has the power of love and some really strong spells. However, I think Dumbledore would be very powerful in this crossover. He has great wisdom and extremely powerful magic. He could probably figure out how to use Naruto's chakra to his advantage if they were on the same side.
Harry and Naruto would be an obvious and interesting pairing. They both have a strong sense of justice and have faced great hardships in their lives. Harry has to deal with the threat of Voldemort, while Naruto has to overcome the prejudice against him as a jinchuriki. They could share their experiences and learn from each other's determination.
I think Hermione would be the most interesting. She's so intelligent and resourceful in the Harry Potter series. In the Hunger Games, she would be able to analyze the situation quickly, figure out the best hiding places, and find ways to outwit the other tributes. Her knowledge of magic would also give her an edge, like using spells to find food or water.
