I think Harry Potter himself would be very interesting. Imagining him learning tennis skills from the Prince of Tennis characters and using his wizarding abilities to add a new twist to the game. He could use his Patronus to guide the tennis ball or something like that.
Hermione Granger could be really interesting too. She'd be the one trying to understand all the scientific and magical aspects of this crossover. She might study how the Prince of Tennis skills work in a magical environment and come up with theories on how to improve them further. Plus, she could use her vast knowledge of spells to help the tennis players in unexpected ways.
One idea could be that Harry Potter and his friends discover a magical tennis court at Hogwarts. The spells in the wizarding world could be used to enhance the tennis skills in a really unique way. For example, a charm could make the tennis ball move like a snitch, adding an element of magic to the game.
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.
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 the H2O mermaid, Rikki, could be a great focus. She's feisty and independent. If she were to meet Harry Potter, she'd probably be both intrigued and a bit skeptical of his magic. Her interactions with the wizarding world characters would be full of drama and discovery as she tries to understand this new and strange magic.
I think Harry Potter himself would be very interesting. Imagine him in Neverland, a place so different from Hogwarts. He could bring his courage and sense of justice from the wizarding world and apply it in the new setting. His magic skills would also be fascinating to see in the context of Neverland, like how he would use spells against the likes of Captain Hook or other threats there.
Definitely Harry Potter himself. His journey through time could be a way for him to gain more understanding of his parents and the events that led to their deaths. He could also try to change some things in the past to make the present better. For example, he could try to prevent Voldemort from ever becoming so powerful in the first place. And seeing Harry interact with the people from the past, like his grandparents or young Dumbledore, would be really fascinating.
In some fanfictions, the Hogwarts houses could be related to the different tennis teams in Prince of Tennis. For instance, Gryffindor could be paired with the Seigaku team as both value courage and determination. The characters' magical abilities might also come into play during tennis matches, like using spells to enhance their speed or accuracy on the court. It creates a whole new dynamic where the two different universes' elements blend together.
Leonidas from '300' would be a great character to focus on. Imagine his reaction to the magic of the Harry Potter world. He's a fearless leader, and seeing him interact with wizards and magical creatures would be fascinating. He might see the magic as a new weapon or a strange form of sorcery that he has to either embrace or fight against.
I think Heero Yuy from Gundam Wing would be really interesting. His stoic and determined nature would contrast greatly with the more emotional and magically - driven characters in Harry Potter. He could bring a new sense of discipline and strategy to the fight against dark forces in the Harry Potter world.
Luna Lovegood would be an unexpected but fascinating choice. Her unique perspective and belief in all kinds of magical creatures could make her very open - minded about the vampires and werewolves in the Twilight world. She might see them as just another type of magical being and try to find common ground, which could lead to some really interesting interactions and storylines.
