Another plot could be a time - travel story. Agent Washington and Agent Texas are sent back in time to a crucial moment in their organization's history. They have to make sure that certain events happen as they should without changing too much of the future. This would involve a lot of sneaking around, gathering intelligence, and dealing with historical figures within their universe.
For Agent Texas, you could develop her character by showing her more vulnerable side. Maybe in a fanfic, she gets injured on a mission and has to rely on Agent Washington more than she's used to. This forces her to open up about her insecurities and fears, which in turn makes her a more well - rounded character. And through their interactions during this time, both characters can grow.
A more complex plot could be a crossover where an evil organization is trying to take over both universes. Naruto and Agent 47 have to find a way to work together, despite their very different backgrounds and methods. They could learn from each other's strengths and overcome their differences to save both their worlds.
One idea could be that Agent Alice and Peter are on a mission to save a world from an unknown virus. They have to work together, combining Alice's intelligence and Peter's physical strength. Along the way, they face various challenges and start to develop a deep friendship.
One idea could be an Agent 47 crossover with the Hitman universe's other assassins. They could team up or compete in a high - stakes mission. Another is a crossover with a detective character from a crime - solving series. The detective could be on Agent 47's trail, leading to a cat - and - mouse chase. Or a crossover with a science - fiction character where Agent 47 has to deal with otherworldly threats in an unfamiliar setting.
One idea could be that Agent Smith somehow gains a new form of consciousness and starts to have a strange alliance with Neo. They might work together to fight a new threat in the Matrix that is even more powerful than the machines. This would be a total role - reversal from their usual antagonistic relationship.
Perhaps there could be a story where Agent Venom is framed for a crime he didn't commit, and Spiderman is the only one who believes in his innocence. They then go on a journey to clear Agent Venom's name while also uncovering a bigger conspiracy in the city. Along the way, they have to fight off other villains who are after them.
One idea could be that Naruto and Agent Carolina are brought together in a crossover universe. They might start as rivals, each thinking their own way of fighting and protecting is superior. For example, Naruto with his ninja skills and Agent Carolina with her high - tech combat abilities. As they face a common enemy, they gradually learn from each other. Naruto could teach Carolina about the importance of teamwork in a more organic, family - like sense that he has with his ninja team, while Carolina could show Naruto some advanced technology that could enhance his fighting capabilities.
Maybe Harry could be a double agent. Working for the wizarding world while also being part of S.H.I.E.L.D. He could be trying to keep the two worlds from colliding in a dangerous way while also using resources from both sides to fight common enemies. For instance, using S.H.I.E.L.D.'s technology to track down dark wizards who are using muggle - made weapons in their evil plans.
Another idea is that Agent Carter is somehow brought to the modern era where Iron Man exists. She could be a bit of a fish out of water, but her old - school skills and no - nonsense attitude could help Tony Stark in a crisis situation. Maybe she has a different perspective on some of the modern technology that he's created and offers some unique solutions.
Another plot could involve Peggy accidentally traveling to an alternate timeline. In this timeline, SHIELD has become an evil organization. She has to team up with alternate versions of her friends and allies to set things right. This would be a great opportunity to explore different character personalities and relationships in a new context, as well as have some intense fight scenes and strategic planning.
