Well, in such a fanfiction, the Avengers could visit the world of Black Butler. They would be quite out of place in the Victorian - era setting. Iron Man might introduce his high - tech gadgets, which would seem like magic to the people in Black Butler's world. Thor could be mistaken for some sort of god in that world, and the cultural clashes and new alliances formed would make for a very interesting read.
A 'glee avengers crossover fanfiction' might involve the characters' unique abilities combining in unexpected ways. For example, Iron Man could use his tech to enhance the Glee club's stage effects.

It could also be a story about how the two groups learn from each other's values, like the Avengers' sense of justice and the Glee club's unity through music.
In a 'batman and avengers crossover fanfiction', it could start with Batman being mysteriously transported to the Avengers' universe. He'd be a bit of a loner compared to the team - based Avengers. However, his intelligence would shine as he helps them deal with threats they've never faced before. For instance, against a new type of enemy that can't be defeated by brute force alone. Batman's utility belt and his ability to plan ahead would be crucial in such a crossover. He might even teach the Avengers a thing or two about being more strategic in their battles.
A 'Avengers Supergirl Crossover Fanfiction' might involve Supergirl's Kryptonian powers being a mystery to the Avengers at first. She could show off her super strength, heat vision, and flight, and the Avengers would be in awe. Then they'd start to strategize together. For example, Captain America would lead the group with his military tactics, while Supergirl uses her powers to do the heavy - hitting. And Hulk and Supergirl could have a fun interaction comparing their strength.
Well, it could be really cool. Maybe the heroes from Boku no Hero Academia and the Avengers would team up to fight a common super - villain. For example, All Might and Captain America could lead the charge, with their strong sense of justice and leadership. The quirks of the BNHA characters combined with the powers of the Avengers would make for some epic battle scenes.
A 'Black Butler' and 'Tokyo Ghoul' crossover fanfiction could have Sebastian from 'Black Butler' serving CCG investigators in 'Tokyo Ghoul'.

His loyalty to the investigators would be a fascinating aspect to explore, as well as how the investigators react to his otherworldly abilities.
It could be really interesting. Sebastian from Black Butler might find Naruto's ninja world full of chaos and yet fascinating. He could use his butler skills to blend in, while Naruto might be intrigued by Sebastian's elegance and power. Maybe Sebastian would be tasked with protecting Naruto for some strange reason, like a contract made by the Hidden Leaf Village elders.
Sebastian would be the most interesting. His demonic nature and his loyalty to Ciel would bring a whole new dynamic to the Avengers. He could easily outmaneuver most of the villains with his wits and powers.

A 'Avengers Game of Thrones Crossover Fanfiction' would be a wild blend of two very different universes. For instance, Doctor Strange could use his magic to travel between the Seven Kingdoms and other dimensions. Hawkeye might find himself in the middle of a hunt in the forests of Westeros, using his archery skills to survive. The Avengers' advanced technology and superpowers would disrupt the medieval - like world of Game of Thrones, and at the same time, the political and moral complexities of Westeros would test the Avengers in new ways.
It could be amazing. Picture Naruto's ninjutsu skills combined with the Avengers' superpowers. Maybe Naruto could teach Hawkeye some new arrow - shooting techniques inspired by his shuriken skills. And Thor could show Naruto how to better control his chakra using the power of Mjolnir.
