In many fanfictions, the female puppet might have a special connection with a child spirit. So that child spirit could be considered a main character as well. Their relationship could be central to the story, like the puppet protecting the spirit or the spirit guiding the puppet in some way.
Another character that could be a main character in these fanfictions is the creator or the owner of the pizzeria. They might have a role in the puppet's origin or be involved in the events that unfold in the story. For example, they could be trying to cover up the secrets related to the female puppet and the other animatronics.
Well, of course, the female puppet is a main character. There could also be other animatronics like Freddy, Bonnie, and Chica. Sometimes, the security guards from the game might also be important characters in the fanfiction as they interact with the female puppet.
In many fnaf the puppet fan fictions, the children's spirits are important characters too. They are often the reason behind the puppet's actions. For instance, the puppet might be trying to avenge the children who met a tragic end in the pizzeria. And then there could be a new character introduced in some fan fictions, like a security guard who stumbles upon the secrets of the puppet and the other animatronics and becomes part of the story.
One interesting fanfiction could be about the female puppet's backstory. Maybe it delves into how she came to be in the FNAF world and her relationship with the other animatronics. It could show her as a protector or a character with a hidden agenda.
Often, she is depicted as mysterious. In many fanfics, she has an air of enigma around her.
The main character is, of course, the female Springtrap. She often has a complex personality, sometimes being menacing and other times showing a more vulnerable side. Other common characters include Freddy Fazbear, Bonnie, Chica, and Foxy. They interact with the female Springtrap in different ways, sometimes as enemies and other times as reluctant allies.
There's often a mentor - like figure in these fanfictions. It could be an old - timer who used to work at the pizzeria and knows a lot about the animatronics. This character helps the female night guard understand the rules and the danger she's in. And of course, the other animatronics like Bonnie and Chica also play important roles.
The animatronics themselves can be considered main characters in a way. Freddy Fazbear, Bonnie the Bunny, Chica the Chicken and Foxy the Pirate Fox play significant roles. They are the sources of horror, with their own distinct personalities (although they are haunted and menacing) in the stories. For example, Freddy is often depicted as the leader among them, and his appearance is always a sign of great danger.
Since I don't know the exact 'friends puppet story', I can't say for sure. But they could be named things like Puppet Bob, Puppet Sally, and Puppet Tom.
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.
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.
The main characters usually include the night guards. They are the ones who have to endure the terrors of the haunted animatronics during their shifts at Freddy Fazbear's.
