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.
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.
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.
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.
Hermione and Death could be an interesting pairing. Hermione is known for her intelligence and thirst for knowledge. Death, being an all - powerful entity in the Darksiders universe, could have a lot of knowledge that Hermione would be eager to learn. Their conversations would likely be deep and thought - provoking as she tries to understand the nature of death from his perspective.
Ron and Brainy Smurf would have some hilarious interactions. Ron is a bit of a goof - off sometimes, and Brainy Smurf is always trying to be the smartest. Brainy might constantly try to correct Ron's 'less - than - perfect' knowledge, and Ron would probably get annoyed but also find it funny. They could end up in some comical situations together, like when trying to solve a riddle that combines the magic of the wizarding world and the Smurfs' logic.
I think it would be really interesting to focus on Hermione. She's so intelligent and curious. In Middle - earth, she could study the different magic and lore there. She might be the one to figure out how to combine the magic of the two worlds. For example, she could try to find a way to use the magic of Middle - earth to defeat Voldemort or help the Fellowship in a different way.
I think Mr. Incredible and Hagrid would be a really interesting combination. Mr. Incredible's no - nonsense attitude and his physical strength combined with Hagrid's love for magical creatures and his knowledge of the wizarding world would make for some great interactions. They could both be involved in a mission to protect a rare magical creature from some villains who want to use it for evil purposes.
Ichigo and Harry Potter would be an interesting pairing. Ichigo's brash and determined nature combined with Harry's sense of justice and leadership could make for some great adventures. They could learn from each other's fighting styles and magical abilities.
Harry Potter himself could be very interesting. He's used to fighting dark wizards in his world, but in Camelot, he'd face different challenges. His skills with a wand and his ability to think on his feet would make him a valuable asset to King Arthur. Also, his status as 'the Boy Who Lived' would give him a certain mystique in Camelot.
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.
