Well, it could be really exciting. Maybe the Avengers have to deal with some vampire - related threats that are similar to the ones in Twilight. For example, they might face a group of vampires who are after some powerful artifact. Iron Man could use his high - tech gadgets to detect the vampires' lair, while Captain America leads the fight against them. And the Twilight characters could bring in their knowledge of vampire lore to help the Avengers out.
In an 'avengers and twilight crossover fanfiction', it might start with the Avengers being called to a small town where strange disappearances are happening, which is later found out to be the work of vampires. The Twilight vampires like Edward could team up with the Avengers. Edward's ability to read minds could be useful in predicting the enemies' moves. The Avengers, on the other hand, would provide the muscle and strategic planning. Thor could use his hammer to take on the stronger vampires, and Black Widow could use her combat skills to fight the faster ones.
In a Glee and Avengers crossover, there could be a plot where the villains from the Avengers' world target the Glee club because they see their unity and positive energy as a threat. The Avengers would have to protect them. Finn could be inspired by Captain America's leadership and try to step up as a leader in the Glee club. And the Avengers might be entertained by the Glee club's musical numbers during their down time.
A Buffy Crossover Avengers fanfiction could be really exciting. Picture Buffy's slaying skills combined with the superpowers of the Avengers. Maybe Buffy could teach the Avengers some new combat moves, like how to fight vampires and demons. And the Avengers could introduce Buffy to new high - tech weapons and strategies. For example, Iron Man could upgrade Buffy's weapons with his technology, while Buffy could show Thor how to deal with magical threats in a more hands - on way.
A Poseidon - Avengers fanfiction crossover could be really exciting. It might start with Poseidon being somehow drawn into the Avengers' world, perhaps through a strange interdimensional rift. He could bring his godly powers to the team, like his control over the seas. His trident could be a powerful weapon against enemies that the Avengers face. Maybe he'd have some initial clashes with the Avengers due to his godly arrogance, but then they'd learn to work together.
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.
Another challenge is the fanbase. Both Twilight and Avengers have huge and passionate fanbases with different expectations. Some Twilight fans might not like how their beloved vampires and werewolves are portrayed when mixed with the Avengers, and vice versa. So, the writer has to be careful to please both sets of fans, or at least not completely alienate either group while creating this crossover story.
Well, in such a crossover fanfiction, perhaps the Avengers are transported into the world of The Walking Dead. Iron Man would be quite a sight, using his high - tech suit to fend off walkers. Captain America could lead the survivors, teaching them his values of justice and unity. And Black Widow could use her espionage skills to figure out the source of the zombie outbreak, which might be related to some HYDRA - like organization in this combined universe.
A Stranger Things and Avengers crossover fanfiction could be filled with lots of interesting storylines. The Upside Down could be a new threat that the Avengers have to face. Steve Rogers could lead the Hawkins kids, teaching them about strategy and combat. Meanwhile, characters like Thor could be intrigued by the strange creatures from the Upside Down. The different powers and personalities of the two universes would create a really engaging and unique story.
The plot might center around a new super - weapon. In the Halo universe, there are powerful weapons like the Halo rings. Imagine if some evil force in the Marvel universe gets hold of this technology. The Avengers and Halo characters would have to work together to stop it. For example, Captain America's leadership skills and the Chief's military tactics would be crucial in formulating a plan to retrieve or destroy the weapon.
The plot might involve the Avengers being called to investigate strange energy signatures which turn out to be related to the AllSpark from the Transformers universe. The Decepticons are after the AllSpark and the Autobots are trying to protect it. The Avengers and Autobots join forces. Thor could use his powers to fight off the Decepticons' attacks from the air, while Hulk could take on the physically strong ones. The fanfiction could also explore how the different personalities of the Avengers and Transformers interact, like the witty banter between Spider - Man and Bumblebee.
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. The Glee characters could introduce the Avengers to the power of music and performance to boost their morale. 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.
