In a fanfiction, Scrap Baby could be the key to unlocking a mystery about the origin of the animatronics' haunted nature. A group of technicians or curious investigators enter the place and find Scrap Baby. As they study her, they start to uncover secrets that date back to the very beginning of the Freddy Fazbear's franchise, and Scrap Baby's actions and reactions play a crucial role in this discovery.
Maybe Scrap Baby forms an unlikely alliance with another animatronic. For example, she teams up with Funtime Freddy to escape the clutches of the evil presence that seems to be controlling the place. They have to overcome their differences and use their unique abilities to find a way out.
Well, you could write a fanfiction where Scrap Baby discovers a way to regain her humanity. She starts to have feelings that are more human - like empathy and remorse. For example, she might feel bad for the children who were lured by the animatronics in the past. Also, a plot could revolve around her trying to communicate with the outside world. She could find a way to send messages, perhaps through glitches in the security system. Another interesting plot could be that she tries to repair herself and the other animatronics to a more 'original' state, hoping to change their fates.
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.
One great fanfiction could be about Scrap Baby and Molten Freddy teaming up to escape the horror of the FNAF world. They might use their unique abilities, like Scrap Baby's agility and Molten Freddy's molten form to their advantage.
Obviously, Scrap Baby herself is a main character. Then there's Lefty, who could have an interesting dynamic with Scrap Baby. Also, the other animatronics from FNAF 6 like Molten Freddy could be important characters. Maybe even the unseen or implied characters like the souls of the children could play a role.
A plot could involve them finding a way to regain their more human - like forms. Maybe they discover a hidden part of the facility that has some sort of restoration device. They would have to work together, with Molten Freddy using his knowledge of the building's layout and Scrap Baby using her intelligence to figure out how to operate the device.
Maybe the baby has some special talent or power that they start to notice as it grows. Brian and Mia have to figure out how to deal with this while also protecting their baby from those who might want to take advantage of this special ability. They go on a journey to find out more about the origin of this power.
Build a vivid setting. Describe the dilapidated pizzeria in detail, the creaking floors, the dimly lit hallways, and the smell of rust and decay. This will draw the readers into the world of the fanfiction. Also, add some mystery elements to the setting, like hidden rooms or strange symbols on the walls.
One idea could be that Sonic and his friends accidentally end up in the FNAF universe. Sonic's speed could be a huge advantage against the animatronics. For example, he could quickly dash around the haunted pizzeria, confusing the animatronics and leading them into traps. Another idea is that the animatronics from FNAF somehow get transported to Sonic's world. The chaos that would ensue as they try to adapt to the bright, colorful and fast - paced Sonic world would be really interesting to write about. Maybe Sonic and Tails would have to figure out a way to send them back while also protecting their friends from the animatronics' unpredictable behavior.
One idea could be that the characters from Undertale find themselves in the FNAF pizzeria. Sans could use his shortcuts to avoid the animatronics' attacks. Another idea is that the FNAF animatronics end up in the Underground. Freddy might befriend Toriel, and she could try to 'fix' them. Maybe Papyrus would be terrified of the animatronics at first but then try to befriend them with his overly friendly nature.
One idea could be that the Naruto characters are trapped in the FNAF world. Naruto, with his determination, might try to find a way out by using his ninja skills. He could use his shadow clone jutsu to search different areas of the haunted pizzeria at once. Sasuke might be more interested in uncovering the secrets behind the animatronics, thinking it could give him some power or knowledge advantage.
