Fans often portray the animatronics with an Electronic Speech Impediment of some kind despite there being little to no indication of that happening in the games themselves. However, this is somewhat believable due to how old the animatronics are said to be and them being possessed.
Speaking of which there are a few consensuses as to how the unvoiced characters would sound like. For example, Freddy is typically depicted as sounding like a Southern Gentleman.
While in Canon it only appears on her bib, "Let's eat!" is often used as Chica's Character Catchphrase in fanworks and she is frequently portrayed as a Big Eater whose Trademark Favorite Food is pizza (which would later become Ascended Fanon as of Help Wanted). Because of her association with food, combined with the fact that she is the only animatronic to enter the kitchen area in the first game many fans like to depict Chica as the Team Chef of the Fazbear gang with a fair number of fan redesigns giving her a chef motif complete with a toque blanche on her head and/or an apron instead of her bib. Overlapping with this characterization and tying in with the stereotype of hens as motherly animals she is sometimes also drawn wearing a dress and an apron around the waist like a typical housewife.
Bonnie and Chica are commonly paired together in fanon due to their role as Freddy's Co-Dragons, their color schemes being a Yellow/Purple Contrast, and their shared method of flanking the player from one side of the room (Bonnie at the left, Chica at the right), which can give the impression that the two are actively cooperating to catch you. There are two general interpretations of their possible relationship (outside of shipping) as a result. Either (a) Bonnie and Chica — often the actual fictional characters In-Universe — are a pair of Platonic Life-Partners or honorary siblings who care deeply for one another, or frenemies/foils who get on each other's nerves and/or bicker a lot.note This also frequently extends to their Toy counterparts, as their dynamic and behavior in the second game deliberately parallels those of the originals. Or (b) Bonnie and Chica are just two animatronics who happen to be possessed by a pair of siblings respectively, usually a boy and a girl.
There's generally two interpretations of Foxy's role in the daytime show. One of them is that he's an adventurous storyteller who provides entertainment when the band needs a break for maintenance or something. The other interpretation portrays him as a Hamburglar-esque villain who causes trouble for the Fazbear group, often in the form of raiding and plundering pizza from them, an interpretation featured in the Freddy & Friends: On Tour! shorts used to promote Five Nights at Freddy's: Security Breach by having Foxy chase the other animatronics around.
The Cap'n Foxy level in The Curse of Dreadbear offers another possible role: Foxy has pirate journeys teaching that friendship is the real treasure.
Fredbear and Spring Bonnie are often subject to this by the fandom due to how little is known about them during their prime.
Many fans' interpretation of Spring Bonnie's daytime role is that he's not just Fredbear's faithful stage partner, but a stringed instrument player much like his successors. To drive home his status as the earliest incarnation of the Bonnie character in-universe, his speculated instrument of choice will usually be an old-fashioned banjo or an acoustic guitar to contrast the electric guitars his later counterparts use.
The Crying Child is shown to be possessing Golden Freddy alongside Cassidy and serving as some kind of Morality Pet; this is because of Golden Freddy likely being a modified and rebuilt Fredbear.
Fredbear and Spring Bonnie have been portrayed as Hostile Animatronics just like the rest of the characters since the time of the third game, when William was physically introduced as the Big Bad in the form of Springtrap. This is despite William's murders happening after FFD, which would mean the possessions would happen after FFD was shut down, and also, there's no reason for the springlock animatronics to be hostile in the first place since they don't have any special features that would cause it like the Toys in 2. As such, it is entirely illogical to make them both hostile like the rest. On the other hand, they are, in canon, possessed by the Big Bad Ensemble of the games up to Pizzeria Simulator: Cassidy for Fredbear (if Golden Freddy is the same character) and William for Spring Bonnie (as the one who possessed Spring Bonnie's model). But that is still only after William's murders, the latter happening long after said murders.
In fan works that feature the original and Toy generations of the mascots together, Other Me Annoys Me will generally be present to varying degrees (especially between the original and Toy iterations of Bonnie) with the older mascots resenting the newer ones for replacing them and leaving them to rot or the latter viewing the former with arrogant disdain due to considering themselves cuter and supposedly superior replacements. If they're shown to be on good terms instead the originals will likely be portrayed as mentor figures of sorts towards the younger Toy characters, usually with the exception of Foxy and Mangle.
It's generally presumed by the fanbase that Ballora is meant to represent William's wife and his children's mother, if not outright being possessed by her. This is out of a mixture of Ballora's voice lines being oddly flirtatious towards William in Ultimate Custom Night, the S.T.A.F.F. tableau in Security Breach that depicts the "mother" as looking vaguely similar to said animatronic, Mrs. Afton being an Ambiguously Absent Parent and Sister Location (the game Ballora debuted in) featuring more of a focus on the Aftons as a whole. While very little is officially established about Mrs. Afton at all, her being Ballora is sometimes said in the same breath as Elizabeth being Circus Baby or William being Springtrap which are both unambiguously canon. Additionally, if she is named in fanworks she'll typically be called 'Clara', after the character from "The Immortal and the Restless".
Speaking of the Aftons, more recent fanon has depicted their patriarch and the Big Bad himself William as a disillusioned man Driven to Madness by the death of his youngest son (commonly named Evan) and only daughter Elizabeth. It also delves into his relationship with his oldest son and child Michael and best friend Henry Emily, the former of whom he holds great disdain for from start to finish and initially thinks very highly of the latter.
The Crying Child (commonly named Evan) is of course depicted as extremely timid and somewhat of a pushover, not at all helped by Michael's Big Brother Bully tendencies which leaves him with resentment towards his older brother. The Child's death following Michael's DeadlyPrank Gone Too Far only sends him over the edge once he possesses Fredbear/Golden Freddy.
Prior to the second game a popular belief was that Foxy caused the Bite of '87 due to his area being closed off and him being in a noticeable state of disrepair. However, putting 1/9/8/7 as the difficulty on the Custom Night after a patch results in a Golden Freddy jumpscare, leading people to suspect Foxy was a Red Herring. The second game largely Jossed this since Foxy was likely in Parts and Service at the time of the Bite.
Fans have agreed the cupcake is a security camera and the fan sucks up all your power.
A popular interpretation of Mangle's days in their prime is that it's not only unambiguously female, but was also very similar in design to Toy Chica (possessing the same curvy figure and pink shorts), with the only difference often being a pink, heart-shaped tuft of fur on its chest. This became Ascended Fanon of sorts in FNaF World with the debut of Funtime Foxy, but as always, the In-Universe character's actual canonical gender is deliberately left vague, and lacks the same curvaceous figure as its typical fanon self.
Shadow Freddy and Shadow Bonnie/RWQFSFASXC, despite not being in the same room together for more than a minute, are usually portrayed/interpreted in the fandom as Those Two Guys in the same vein Fredbear and Springbonnie used to be.
Crossing over into Memetic Mutation, Ennard's Trademark Favorite Food to the point of obsession is exotic butters. In the game itself, Ennard has absolutely nothing to do with the exotic butters, but according to fans it followed Eggs Bennedict home to steal his butters, killed him to get to the butters, can be pacified by offering it butters, will kill people who take its butters, and so on.
Canonically, Ennard has no confirmed gender due to being an amalgamation, and it speaks with a female voice. Despite this, it's far more common to see it being referred to as "he" rather than "they" or "it".
Prior to Vanny's proper reveal for Security Breach, the rabbit mask that appears as an Easter Egg in Help Wanted was frequently used as the basis for fan depictions of Vanny in her rabbit costume, portraying the suit with black patches of fur instead of the crude stitching and patchwork of its official design. Additionally it was common to portray her as a Goth prior to implications that her real personality is that of a Glurge Addict with stereotypically girly interests and she and the blonde security guard named Vanessa in the teasers are one and the same.
If the animatronic cast gets humanized expect to see Monty depicted as a dark-skinned man to go with his Deep South voice.
In the game proper, Glamrock Bonnie is a Posthumous Character who never makes any physical appearance apart from his cameos as the mascot of the Pizzaplex's bowling alley and a difficult-to-find sketch. In fanart depicting his speculated true appearance, what little is seen of Glamrock Bonnie in the gamenote assuming it is him and not just cameos of the original Bonnie, given his Reused Character Design tends to be used as the basis for his design, usually being portrayed with his signature red bowling shirt plus the tattoos and/or accessories of a typical glamrock musician.
In the 2-Star "Escape" or even "True" endings, lots of fans like to portray Glamrock Freddy as having to wear a hugehoodie◊ to hide◊ his identity or not to arouse too much suspicion due to being a huge animatronic. While it's not obviously the best disguise, quite a lot of fans still like the idea due to how well Glamrock Freddy pulls off a hoodie.
Vanny/Vanessa is sometimes depicted with purple eyes in fanart, to emphasize the control Glitchtrap has on her psyche. Canonically, there's no indication that Vanessa's eyes change when she's under Glitchtrap's influencenote Vanessa's eyes in a Freeze-Frame Bonus in the fourth and final episode of Freddy & Friends: On Tour! do appear more yellow, but that could be chalked up to the distortion of the video rather than any actual change in their color, and her eyes consistently remain the same green color. However, in the True Ending, Freddy's eyes change to a shade of purple when Afton starts hacking him.
The most common interpretation of Gregory, Freddy, and the newly freed Vanessa's dynamic post-3 Star ending is a Family of Choice. The reasoning is likely because of Freddy already being a Team Dad, and Vanessa not only being an adult who can take in a homeless child, but would need all the emotional support she could get after what Glitchtrap did to her.That, and it's a cute subject to base entire fan works on.
