Another idea could be a story where Ant - Man has to deal with a giant ant that has gone rogue. The giant ant could be a result of some scientific experiment gone wrong. Ant - Man would then have to use his skills and the help of the other ants in the colony to stop this rogue ant from causing destruction in the city. He might have to figure out a way to communicate with it and calm it down, or if that fails, find a way to defeat it without harming the rest of the ant colony.
One idea could be an OC who is a scientist working alongside Hank Pym. They could be developing a new type of Pym Particle with unique properties.

One idea could be a fanfiction where Ant Man and Wasp team up with other superheroes to fight a new, powerful villain from another dimension. They would have to use their unique shrinking and flying abilities in creative ways to outwit the enemy.
A plot idea could be that the Ant Man and the Wasp get their powers swapped accidentally. This would lead to a lot of comical and also challenging situations as they have to adapt to each other's abilities. They would need to learn how to use the new powers quickly in order to face a new villain who is taking advantage of the chaos. Also, perhaps the Wasp's suit could have some hidden features that are only revealed when Ant Man tries to use it, which could add an interesting twist to the story.
One idea could be a story where Ant Man and Spiderman team up to stop a new villain who has the ability to shrink and control insects on a large scale.

One idea could be to write about an ant that discovers a magical portal in the ant farm and travels to a different world. Maybe it's a world full of giant food sources and friendly creatures that help the ant on an adventure.
One idea could be a story where Ant - Man and Black Widow team up for an undercover mission. They have to infiltrate a high - security facility where the bad guys are developing a new weapon. Ant - Man uses his size - changing abilities to get into small spaces and gather intel, while Black Widow uses her combat skills and charm to distract the guards.
Another plot idea is that the pregnancy causes a rift between Ant - Man and The Wasp. They might have different ideas about how to handle the situation, like whether she should continue being a superhero or focus solely on the pregnancy. This conflict could drive the story as they try to work through their differences and come together for the sake of their family.
A plot could revolve around Scott and Hope's relationship facing a test. For example, a powerful entity tries to split them apart by creating misunderstandings. They then have to work through these issues while also dealing with threats to the city. They might discover new things about each other's pasts that either strengthen or strain their bond.
One interesting plot idea could be that when they swap bodies, they have to keep it a secret from their enemies. So they have to quickly learn to mimic each other's behavior and powers well enough to not raise suspicion. For example, Ant Man in The Wasp's body has to act all confident and in - control like she usually does during a mission.
One interesting fanfiction could be where Ant - Man and Spider - Man team up to stop a villain who can manipulate time. In this story, Spider - Man's agility and Ant - Man's ability to shrink and grow would create some really cool action scenes.
