A more complex plot could be that Tyler is actually a reincarnation of someone who was wronged in the FNAF backstory. The animatronics sense this and are initially hostile, but as Tyler starts to remember his past life, he is able to use his knowledge to try and bring peace to the pizzeria. He might have to face off against an evil force that has been using the animatronics for its own malevolent purposes.
For Tyler, you can start by giving him a clear backstory. Maybe he's a big FNAF fan, so he has a lot of knowledge about the lore which he can use to his advantage. His reactions to the dangerous situations in the pizzeria should be realistic, like being scared at first but then gradually getting more determined.
A plot could involve the male reader being the only one who can see the true form of the animatronics, not just their creepy, haunted versions. He tries to convince others that the animatronics are not all bad and that there is a way to save them. Another idea is that the male reader accidentally gets trapped in a virtual reality version of the FNAF world and has to find a way to escape while also dealing with the virtual animatronics. There could also be a plot where the male reader is related to the original creator of the animatronics and has to come to terms with his family's legacy and the dark secrets that come with it while interacting with the animatronics.
One plot idea could be that the animatronics initially see Mike as a threat but gradually come to understand his good intentions. Maybe Mike has a special ability that allows him to communicate with them in a unique way, leading to a series of adventures where they have to work together to solve a mystery in the pizzeria. For example, they might be trying to figure out the true origin of the strange occurrences in the building.
One idea could be that Gregory is lost in the spooky FNAF world and Vanessa, who initially seems menacing, actually turns out to be his protector. She could use her knowledge of the place to keep him safe from the animatronics.
Perhaps there is a prophecy in the FNAF world that only Scrap Baby and Molten Freddy together can fulfill. They start off not believing it but as strange events unfold around them, they begin to think there might be some truth to it. This could lead to a journey of self - discovery for both of them as they try to figure out what they need to do to fulfill the prophecy.
Maybe Gregory is lost in the pizzeria and Vanessa, who initially has her own motives, gradually forms a bond with him. They could team up to face the haunted animatronics together, with their relationship evolving from distrust to a strong friendship or something more along the way. As they explore the dark corners of the place, they learn more about each other's pasts.
One interesting plot idea could be that Foxy and Mangle team up to solve the mystery behind the strange happenings in the pizzeria. They use their unique animatronic abilities to uncover secrets.
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.
