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.
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.
Alice from Twilight could be a fascinating character to focus on. Her ability to see the future could play an interesting role in a crossover. She could either help or hinder the Ghost Adventures crew in their investigations. Maybe she sees something in the future that involves the ghosts and tries to prevent or encourage the crew's actions.
Rachel Berry from 'Glee' would be a key character. She is so ambitious and has a strong vision for music. In a crossover, she could clash with Aubrey from the Barden Bellas over leadership and musical direction. This conflict could drive the story forward as they both try to prove their way of doing things is the best.
Alucard from Hellsing would be really interesting. He has such a long and complex history, and his powers are very different from the Twilight vampires. Putting him in a situation with the Twilight characters would create a lot of drama. For example, his non -chalant attitude towards killing and his dark sense of humor would contrast greatly with the more brooding and 'good -guy' Twilight vampires.
I think Loki would be really interesting. He's always the trickster in the Avengers world. In a crossover with Glee, he could use his magic to create some wild and wacky musical illusions. He might even try to take over the Glee club and turn it into his own little kingdom of chaos.
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.
Raphael could be really interesting. In the 2003 version, he is hot - tempered and tough. In the 2012 version, he also has a strong personality. Seeing how he reacts to his counterpart and how they might either clash or bond could be a great focus. Maybe they have a friendly rivalry as they compare their fighting skills.
Ross could be really interesting. Since he's an archaeologist, in a crossover with a show like 'Indiana Jones' (in a fanfiction sense), he could go on an adventure with Indiana Jones. Ross would bring his academic knowledge while Indy would have the practical experience. Their interactions would be filled with Ross trying to over - analyze everything and Indy just wanting to get the job done.
Chiaki Nanami could be an excellent choice. She is the Ultimate Gamer, so if you cross her with a digital or virtual world, there are so many possibilities. She could use her gaming skills to navigate through a new digital realm, like a Matrix - like world. Her calm and intelligent nature would also make her a great character to lead the group in a crossover situation. She could figure out the rules of the new world quickly and help the others adapt.
I think Barry Allen and Rachel Berry would make an interesting pairing. Barry is all about saving the day and being a hero, while Rachel is very ambitious and determined in her singing career. They could learn from each other's perseverance. For instance, Barry could teach Rachel about the importance of quick thinking in difficult situations, and Rachel could inspire Barry with her unwavering dedication to her art.
