One more key element is the conflict. It could be a conflict between the two groups at first, like misunderstandings due to their different ways of operating. Or it could be an external threat that forces them to work together. This conflict drives the story forward and makes the reader interested in seeing how the characters from these two different shows will resolve their differences and work towards a common goal.
One great piece of 'Supernatural Agents of Shield' crossover fanfiction is 'The Convergence'. It combines the spooky elements from 'Supernatural' with the high - tech and team - based action of 'Agents of Shield'. The characters from both universes interact in a really interesting way, like Dean Winchester being skeptical of all the high - tech gadgets at Shield.
One idea could be that Supergirl's powers are misinterpreted by Shield as a new threat. So they send some of their agents to investigate. The agents then realize she's actually a hero and they team up to fight a common enemy like a powerful alien race that's planning to invade both their worlds.
When writing an Agents of Shield crossover fanfiction, think about how the different technologies and magic systems (if applicable) will interact. If you're crossing over with a fantasy world, how will the Shield agents deal with magic? And how will the magical beings react to the high - tech gadgets? Also, focus on the character development. Let the characters from both universes grow and change as a result of their interactions. You can start with a small event that escalates into a big adventure for all of them.
First, you need to understand the characters well. For Supergirl, know her powers, her moral code, and her relationships. For Agents of Shield characters, like Coulson, Daisy, etc., study their personalities and abilities. Then, create a believable scenario for their meeting. It could be something like a shared threat or an accident that brings them together.
One great Agents of Shield crossover fanfiction is the one where they cross over with the X - Men universe. It's really interesting to see how the characters from Agents of Shield interact with mutants. The story often has some great action scenes and character development as they face new threats together.
Themes of destiny and free will also play a big part. In both shows, the characters struggle with their fates. In a crossover, they can compare notes on how they've dealt with prophecies and whether they believe they can change their destinies. For instance, Merlin was prophesied to bring about great change, and the Winchesters have often been part of prophecies in their own world.
The plot of such a fanfiction could revolve around a mystery that combines the two universes. There could be a villain who wants to steal Wonka's secret recipes and use them for evil purposes, and the Agents of Shield are the only ones who can stop it. They'd have to navigate the sweet yet dangerous world of Wonka's factory, facing off against the villain's minions while also trying not to get distracted by all the delicious treats. It would be a story full of action, humor, and a touch of magic.
One possible plot could be that Batman somehow gets transported to the world of Agents of Shield. Maybe a strange experiment by Hydra goes wrong and creates a portal. Batman would then use his detective skills to figure out what's going on with all the super - powered and high - tech stuff in the Agents of Shield world. He might team up with Coulson and his team to stop a common enemy, like a new super - villain created by a combination of Gotham's criminal minds and Hydra's evil plans.
Well, one possibility is that the characters from Agents of Shield could bring their high - tech gadgets and strategic thinking into the world of Snake Eyes. For example, Fitz could create some new type of weapon or device that helps Snake Eyes in his missions. Another possibility is a clash of ideologies. The more morally grey areas that Agents of Shield sometimes delves into could contrast with Snake Eyes' more straightforward sense of honor. Also, a crossover could lead to some interesting team - up dynamics. Maybe Daisy and Snake Eyes could combine their combat skills in a fight against a common enemy.
One key element could be the character development of the original character (OC). For example, showing their backstory, how they got involved with the Rising Tide. Another important part is the interaction with the Agents of Shield. Maybe the OC starts as an adversary to the agents but gradually comes to understand their mission and may even help them. Also, the fanfiction should capture the essence of the Rising Tide group, like their ideology of transparency and how that affects the OC's actions and decisions.
