A fanfic could revolve around a technology exchange. Tony, being a genius in Earth - based technology, is intrigued by the advanced tech Carol has encountered in space. They work together to combine their knowledge, which leads to some amazing inventions that help save the world in an unexpected way. For example, they might create a new type of energy source that can power the entire planet while also being a weapon against their enemies.
You should also consider their backgrounds. Carol has military training and has been through a lot in space, while Tony grew up in a wealthy family on Earth and has his own set of traumas from his superhero experiences. When they work together, Carol might be more methodical and by - the - book, while Tony is more likely to improvise. Their interactions could be a clash of these two styles at first. As they get to know each other better, they start to adapt to each other's ways. For instance, Carol might learn to be more flexible from Tony, and Tony might learn some discipline from Carol.
A great plot could be a story where Peter and Carol have to mentor a new group of young superheroes. They could have different teaching styles - Peter being more relatable and street - smart, while Carol is more about discipline and using one's full potential. This could lead to some interesting clashes and also moments of great teamwork as they guide the young heroes through various challenges.
It should also include some unique plot twists. Maybe Carol discovers a new aspect of her powers that was not shown in the movie and this changes the course of the Endgame. Or perhaps she has a secret connection to one of the villains that no one expected. These twists keep the reader engaged.
A great Carol Danvers and Monica Rambeau fanfic often includes references to their comic book history. It gives a sense of authenticity and depth to the story. It can be something as simple as mentioning a particular event from the comics that shaped their characters. The fanfic should also be inclusive and diverse, not just in terms of the characters' backgrounds but also in the themes it explores. It could deal with topics like family, identity, or power dynamics in a way that is both relevant to the characters and thought - provoking for the readers.
One plot idea could be that they team up to solve a global crisis. Maybe a new super - weapon has been developed by a common enemy, and their combined skills in technology (Tony) and detective work (Batman) are needed to stop it. They start off a bit wary of each other, but as they work together, they realize they have more in common than they thought.
Well, an interesting plot could be that Tony discovers he's pregnant in the middle of a big battle or some sort of crisis situation. He then has to figure out how to keep it a secret from the villains while also preparing for the baby. Also, there could be a plot where he uses his genius to create new tech to help with his pregnancy, like a special suit that can also monitor the baby's health.
Another fanfic could be set in an alternate universe where Gotham and New York City are in some sort of alliance. Bruce Wayne and Tony Stark are forced to work together to fight a common enemy that is using both cities' resources for evil. Their different fighting styles and personalities clash at first, but over time they develop a deep respect for each other and become friends.
One idea could be that Tony Stark somehow discovers the wizarding world while working on a new technology. Maybe his sensors pick up some strange magical energy. He then meets Harry Potter and they team up to face a new threat that combines magic and technology, like a dark wizard using Stark Industries' tech for evil purposes.
One idea could be that Percy and Carol are brought together by a cosmic event. Maybe a powerful artifact from Percy's world has been lost in the cosmos and Carol, while on a space mission, stumbles upon it. This leads to them having to work together to figure out how to return it safely. Another could be a crossover where the gods from Percy's world are threatened by an intergalactic force, and Carol is called in to help. She has to learn to work with Percy and his demigod friends to fight this new threat.
One idea could be a crossover where Carol Danvers, with her superpowers, accidentally lands in the wizarding world of Harry Potter. She could be initially confused by the magic there, which is different from her own powers. Then, she might team up with Harry and his friends to fight a common enemy that threatens both the Muggle world she's from and the wizarding world.
