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.
Nico di Angelo would be an interesting choice. His dark and brooding nature along with his powers over the dead would be a contrast to the more light - hearted aspects of the Harry Potter world in some ways. He could introduce the wizards to the concept of the Underworld and the spirits. And his ability to shadow - travel could be used in some really creative ways, like getting the group in and out of dangerous situations quickly, whether it's in Hogwarts or in the magical areas related to Greek mythology.
I think Harry Potter himself would be very interesting. Imagine him in the world of Twilight, with his Gryffindor courage facing the dangerous vampires and werewolves. His magical skills could give him an edge in this new and strange world, and he might also learn some things from the Twilight characters about their different kind of 'power' which is more physical and instinct - based.
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 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 it would be really interesting to focus on Hermione. Her thirst for knowledge would make her eager to learn about the world of Eragon, especially the dragon - riding and the different types of magic. She could also bring her logical thinking and problem - solving skills to the table, which would be very useful in both worlds.
I think Clary from Shadowhunters would be really interesting. She's a strong - willed and powerful shadowhunter. If she were to cross paths with the Twilight characters, her inquisitive nature would lead her to try and understand their world. And her skills as a shadowhunter could be put to the test when dealing with the vampires and werewolves in Twilight.
Edward would be really interesting. His brooding and mysterious nature from Twilight would contrast sharply with the often over - the - top and energetic world of Glee. He could bring a sense of depth and angst to the Glee club. His musical talent, which was hinted at in Twilight, could be explored more fully in the Glee setting. He might struggle with fitting in, not because he's not talented, but because of his vampire secrets.
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.
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.
