Another plot idea is a backstory exploration. Maybe the story could show how the Marionette and the Security Puppet came to be in the pizzeria in the first place, and their initial interactions with the animatronics and the children. This could involve some kind of tragic event that bound them to the place. For example, they were both created by a well - meaning but ultimately doomed inventor who wanted to bring joy to the children, but things went horribly wrong.
A third plot idea could be a redemption arc for one of them. Let's say the Marionette has been seen as a somewhat malevolent figure, but through its interactions with the Security Puppet, it begins to change. The Security Puppet could be the catalyst for this change, showing the Marionette that there is another way to deal with the chaos in the pizzeria. They could then work together to bring some sort of peace to the haunted place.
One idea could be that the Marionette and the Security Puppet have to team up to protect the children's spirits in the haunted pizzeria. They might face a new and powerful threat that forces them to put aside any differences.
One common theme is protection. Since both the Marionette and the Security Puppet are often associated with safeguarding something in the FNAF lore, fanfictions usually revolve around their role as protectors. It could be protecting the children's souls or the pizzeria itself.
One interesting plot idea could be Gregory and Vanessa teaming up to solve a mystery within the Pizzaplex that involves the malfunctioning animatronics. They could start off as distrustful of each other, with Vanessa being initially suspicious of Gregory's presence. But as they face various threats together, they gradually learn to trust and rely on one another.
Some interesting fanfiction ideas could involve the animatronics' dreams or nightmares. Imagine writing about what Freddy dreams about at night when he's not active. You could also write a story where the animatronics start to develop emotions that are more human - like. For instance, they feel love, jealousy or sadness. And another idea is to have a crossover with another horror or science - fiction franchise within the FNAF Security Breach universe. Like, what if some characters from Alien were to appear in the pizza plex?
One common theme is mystery. Since both puppets have their own enigmatic qualities in the FNAF world, fanfictions often play on that mystery, like uncovering their pasts or hidden powers.
One plot idea could be that Vanessa discovers Gregory is not just an ordinary child in the mall. She realizes he has some special connection to the animatronics or the secrets of the place. Maybe Gregory is the key to unlocking a mystery that has been hidden for years. For example, he could be related to the original creator of the animatronics in some way. Another idea is that Vanessa tries to protect Gregory from the more malicious animatronics while also trying to figure out his true identity. They could form an unlikely alliance and start to trust each other as they face the various threats in the mall together.
There are some interesting ones. You can check out fanfiction platforms like FanFiction.net or Archive of Our Own. Just search for 'fnaf puppet x security puppet' and you'll find a variety of stories, but the quality can vary.
A possible plot is that Female Bonnie has a malfunction that gives her a different personality. She starts to act more like a protector of the other animatronics instead of scaring the night guard. She might try to fix the broken relationships between the animatronics and the humans. For example, she could leave little hints for the night guard about how to keep the pizzeria safe from the more malevolent animatronics. Or she could be on a quest to find the original blueprints of all the animatronics to understand their true purpose.
One idea could be that Foxy from FNAF crosses over into another universe where he teams up with a group of unlikely heroes. Maybe he uses his speed and stealth to help them in a battle against a common enemy.
One idea could be a story where Foxy and Mangle team up to escape the haunted pizzeria. They face various challenges like dodging the other animatronics and solving puzzles within the building.
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.
