Fat Amy and Emmett would be a hilarious pairing. Fat Amy's over - the - top and fearless personality combined with Emmett's big - hearted and strong - willed nature. They could get into all sorts of comical situations. Maybe they start a side - project within the a cappella group or in the vampire world. Fat Amy could make Emmett laugh like no one else, and Emmett could protect Fat Amy from any threats, whether it's from jealous vampires or rival a cappella groups.
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.
The Doom Slayer and Ruby. Ruby is young and full of hope, always looking for adventure. The Doom Slayer is a stoic, battle - hardened warrior. Their interaction would be really interesting. Ruby could be in awe of his strength and weapons, and the Doom Slayer might see a bit of his own unwavering will in Ruby.
I think it would be Loki. In this crossover, Loki could use his trickery to manipulate the Twilight vampires. He might see them as a new tool to achieve his goals. He could pretend to be on their side and then turn on them when it suits him. His magic and cunning would add a whole new level of chaos to the story.
Gray and Sango might make for an exciting pair. Gray with his ice - make magic and Sango with her weaponry skills. Gray could create ice weapons and structures to assist Sango in battle, and Sango could show Gray some of the more traditional combat techniques. Their personalities are also quite different, with Gray being more laid - back (most of the time) and Sango being very determined and focused on her goals.
Definitely Cortana and Tyrion Lannister. Cortana is highly intelligent and has access to a vast amount of knowledge. Tyrion is known for his wits. They could form an alliance where Cortana provides strategic advice based on her analysis, and Tyrion uses his political acumen to make things happen. Their conversations would be really fascinating as they come from such different worlds but are both very clever.
I think Naruto and Stewie would be an interesting pair. Stewie is this super - intelligent, somewhat evil - minded baby, and Naruto is a powerful ninja with a big heart. They could have some really intense battles of wits, with Stewie trying to outsmart Naruto and Naruto using his ninja intuition to see through Stewie's plans.
I think Naruto and Captain Kirk would make an interesting pair. Kirk is known for his boldness and leadership, while Naruto has his unwavering determination. They could learn a lot from each other. Kirk could show Naruto how to lead in a more structured Starfleet way, and Naruto could teach Kirk about the power of friendship and never giving up in the face of seemingly impossible odds.
I think a pairing between Klein and Togusa could be fascinating. Klein's more laid - back nature compared to Togusa's by - the - book style could lead to some interesting interactions. And they could both bring different skills from their respective worlds when facing challenges in a crossover situation.
I think a pairing between Ben and Tali would be really cool. Tali is a brilliant engineer, and Ben's Omnitrix is a high - tech device. She could help him understand and maybe even upgrade it, while he could protect her with his alien powers during their adventures.
