It could be Voldemort. If he discovers the existence of Greek gods and demigods, he would surely try to use their powers for his own evil purposes. His attempts to manipulate Percy and Annabeth or use their powers against them would create a lot of tension and interesting plot twists in the crossover fanfiction.
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 Annabeth would be the most interesting. Her intelligence and strategic thinking could bring a new dimension to the magical battles in the Harry Potter world. She would be constantly analyzing the magic and coming up with plans that the wizards might not have thought of. Also, her knowledge of Greek mythology could help uncover secrets in the wizarding world related to ancient magic.
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.
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.
Darth Vader and Voldemort would make an extremely interesting combination. Their dark powers and thirst for domination are quite similar. The way they would interact, whether they'd form an alliance or be at odds, could create a very engaging storyline.
Hermione Granger would also be an interesting character to focus on. She's extremely intelligent and curious. In a crossover, she would be the one trying to figure out how The Flash's powers work from a scientific and magical perspective. She might even try to find a way to combine magic and the Flash's speed for some greater good. Her inquisitive nature would make for some great interactions with The Flash and would add a lot of depth to the crossover story.
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.
I think Geralt would be really interesting. He has such a different background and set of skills compared to the characters in Harry Potter. His no - nonsense attitude and his experience with all kinds of monsters would make for some great interactions with the Hogwarts students and faculty. He could be a bit of an outsider, but also a valuable ally in the fight against dark forces.
Dumbledore and Carlisle Cullen would also be a fascinating pair. Dumbledore is a wise and powerful wizard, and Carlisle is an old and moral vampire. They could have deep discussions about life, death, and the responsibilities that come with their powers. They might also collaborate to find solutions to problems that affect both their worlds.
Hermione Granger and Rukia Kuchiki could make a great pairing. Hermione is extremely intelligent and well - versed in magic theory. Rukia, on the other hand, has a deep understanding of the spiritual world. They could collaborate on researching a strange phenomenon that is occurring between the two worlds, like a merging of certain spells and Soul Reaper techniques. Their different personalities would also create some interesting interactions, with Hermione being more outspoken and Rukia more reserved.
I think Buffy and Hermione would make an interesting pairing. Hermione's intelligence and knowledge of magic combined with Buffy's combat skills could lead to some great adventures. They could learn a lot from each other.
