A mystery - themed fanfiction would be cool. For example, there are strange happenings in Mystreet that seem to be centered around Aaron and Aphmau. They have to work together to solve the mystery, and along the way, their feelings for each other deepen. It could involve things like hidden secrets in the houses or strange disappearances of the neighbors.
One idea could be a time - travel plot. Maybe Aphmau gets sent back in time to the early days of Mystreet and has to navigate the relationships and events all over again, but this time with her future knowledge. This could lead to some really interesting changes in her relationship with Aaron.
One plot idea could be that the characters from MyStreet end up in the FNAF pizzeria. They initially think it's just a strange place but soon realize the danger of the animatronics. Another idea is that the FNAF animatronics somehow enter the MyStreet world and start causing chaos among the peaceful MyStreet community. For example, Freddy might try to take over the local diner in MyStreet, thinking it's his territory.
One idea could be that the characters from Mystreet end up in the world of BatIM. Maybe Aphmau and her friends are trying to find a way back home while being chased by the Ink Demon. Another could be a character from BatIM somehow enters the Mystreet universe and causes chaos among the residents there.
Another interesting concept is a crossover with a high - fantasy world like The Lord of the Rings. The Mystreet characters could be transported to Middle - earth. They would have to deal with orcs, wizards, and all the magic and danger that comes with that world. It would be fascinating to see how their relationships and personalities develop in such a different and dangerous environment.
Another interesting concept is a love story that crosses the two universes. A pirate from Pirate Isles falls in love with a Mystreet character. But they have to overcome the differences in their worlds, like the pirate's lawless lifestyle and the Mystreet character's more civilized upbringing. They might meet during a strange magical event that links the two places.
Some aarmau fanfictions focus on their backstories. Maybe a story about how they first met as children but didn't realize the significance of their encounter until years later when they are reunited and the feelings start to resurface.
Katelyn would be a great addition. She has a strong personality and her friendship with Aphmau can add depth to the story. Her interactions with Aaron can also create some interesting drama or comedic moments, like when she is overly protective of Aphmau.
One idea could be exploring the unspoken stories of the ranch hands. Maybe there's a hidden love affair between two of them that has to be kept secret due to the social norms of 1923. Another could be focusing on how a young character dreams of leaving the ranch and going to the big city, but faces many obstacles. And a third idea could be a mystery plot where strange things start happening on the ranch and the characters have to figure out what's going on.
Well, perhaps there's a magical portal that connects the Mystreet universe and the Skymedia one. Characters from both start to swap places randomly. The chaos that ensues as they try to figure out how to get back to their own worlds while also dealing with the cultural and environmental differences of the other world could be really engaging. For example, a character from Mystreet might be shocked by the advanced technology in Skymedia's world, while a Skymedia character could be fascinated by the magic in Mystreet.
A popular plotline also deals with the future. After the baby is born, they think about how their lives will change. Will they move to a bigger place? How will they raise the child? These are all things that are often explored in Aarmau pregnant fanfictions. For instance, they might decide to raise the child in a more magical - influenced environment if their world has magic in it.
One idea could be Android 21's struggle to fit into a world that fears her. She has to prove that she's not a threat and tries to make friends. Another could be her discovery of new powers and how she uses them for good. Maybe she teams up with other characters to fight a common enemy.
