An OC could be a thief who gets hold of some Pym Particles by accident. They then start using them for their own gain in the criminal underworld. But as they use the particles more and more, they start to realize the consequences of their actions and eventually have to team up with Ant - Man to fix the mess they've made.
Perhaps an OC who is a super - powered individual from another dimension where the laws of physics are different. They end up in the Ant - Man universe and their powers interact in strange ways with the Pym Particles. They could initially be seen as a threat but later become an ally in fighting a common enemy that threatens both their worlds.
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. For example, instead of just shrinking and growing, it can also change the density of objects. This OC could face challenges like dealing with rival scientists who want to steal their research.
One idea could be an ant with a unique mutation that gives it extraordinary powers in the ant farm. For example, it can communicate telepathically with all the other ants. Another idea is a story about an ant that goes on a journey outside the ant farm and discovers a whole new world filled with different types of insects and has to find its way back home. Or perhaps a story of an ant that tries to change the social hierarchy within the ant farm to make it more equal.
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 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. They'd have to combine their unique skills, with Spiderman using his webs to swing around and Ant Man shrinking to get into small places the villain might be hiding.
One idea could be creating an OC (Original Character) who is a young martial artist from a different part of the world coming to Ip Man's school to learn. This OC could bring in new fighting styles and cultural elements, leading to interesting exchanges with Ip Man and his students.
One idea could be creating an OC who is a devil hunter from a different country with unique fighting techniques. For example, an OC from a martial - arts - rich nation like Thailand, who uses Muay Thai moves along with devil - powered weapons. Another idea is an OC that is half - devil and half - human, struggling with their identity and trying to find their place in the world of Chainsaw Man. They could have powers that are a blend of both devil and human capabilities, making their story full of internal conflict.
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 male OC who has a special ability related to ants. For example, he can communicate with them on a deeper level than the normal nen abilities in Hunter x Hunter. He could use this to his advantage in battles or to gather information. Maybe he discovers a hidden ant colony that has some unique secrets about the world of Hunter x Hunter.
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.
