Freddy Fazbear is a brown animatronic bear with a light brown belly and swollen mouth. He has bushy black eyebrows, three-toed feet, and three black freckles on the sides of his muzzle. Under his palms and fingers, his footprints look like claws. His round ears are articulated so they can move back and forth (similar to several other animatronic ears). Freddy's lower jaw has boxy human teeth, and, like most animatronics in a pizzeria, his upper jaw has no visible teeth. Freddy performs for the kids during the day at Freddy Fazbear's Pizzeria. At night, Freddy and other animatronic characters wandered the restaurant, attacking overnight guards. He is the titular antagonist of the Five Nights at Freddy's series, who later appears as multiple variations in the succeeding games.

Golden Freddy is a yellow animatronic bear of mysterious and unknown origin who appears to be a cross between Freddy Fazbear and Fredbear but has no eyes. He appears occasionally in Five Nights at Freddy's, who is later revealed to be an apparition of a character called Fredbear, the in-universe precursor to Freddy Fazbear. In Five Nights at Freddy's 2, Golden Freddy takes a form mimicking Withered Freddy's appearance as a unique model of his own. He appears to be in a decrepit state, much like the other withered animatronics, with a missing left ear, and a good deal of damage with loose wires and exposed parts. In Five Nights at Freddy's AR: Special Delivery, his appearance is the same as in the first game, but he is now completely golden, including his teeth, and he is shinier.

Toy Freddy is one of the main antagonists and toy animatronics of the Five Nights at Freddy's series, first appearing in Five Nights at Freddy's 2. Freddy was the mascot for the newly renovated Freddy Fazbear Pizza in 1987, but the pizzeria was closed after only a few short weeks of operation, and the toy Freddy and other toy animatronics were scrapped due to possible malfunctions. Toy Freddy is plastic recreation of Freddy made with parts salvaged from the "withered" originals and equipped with facial recognition. Unlike the other animatronics, Toy Freddy is friendly and affable towards the player and will not commit any harm to them unless something in his direction goes wrong, in which case, he will get heated up about it. This type of behavior is seen in Ultimate Custom Night, where he would get furious at the player that he lost the "Five Nights with Mr. Hugs" game.

Shadow Freddy is a mysterious shadow variant of Freddy Fazbear that appears in the Five Nights at Freddy's series, first introduced as an Easter egg in Five Nights at Freddy's 2 and appearing in subsequent games. Shadow Freddy is a darker version of Withered Golden Freddy, whose appearance is identical to the "withered" appearance of Golden Freddy in Five Nights at Freddy's 2, except that he has been recolored dark purple. Unlike Golden Freddy, he has big bright eyes and teeth. In Freddy's Night 3, Shadow Freddy's eyes and teeth lack the glowing white effect. Instead, his color is a sickly dark green; in contrast to these phantom cartoons. Shadow Freddy's demeanor is unexplored, except for random appearances and disappearances like RWQFSFASXC. His normal personality reveals nothing but mystery, darkness, and the fact that not much seems to be known about him yet.

Phantom Freddy is a damaged and burnt hallucination of Freddy Fazbear from the Five Nights at Freddy's 2, who first appeared in Five Nights at Freddy's 3. Phantom Freddy has the same details as Golden Freddy from Five Nights at Freddy's 2, but like the other phantoms, he has white pinprick pupils in his eyes. He appears to be charred or burned, possibly foreshadowing a fire at the establishment. His teeth look slightly green (but this is most likely due to lighting). In Five Nights at Freddy's: Help Wanted, Phantom Freddy has a completely different look. He now uses the classic Freddy model from the original Five Nights at Freddy's, albeit transparent in some places, revealing the endoskeleton underneath. He also seems to have suffered some damage, with tears on his costume.

Nightmare Freddy is a Nightmare variant of Freddy Fazbear that first appeared in Five Nights at Freddy's 4. Nightmare Freddy is more tattered and exaggerated than Freedy's torn appearance in Five Nights at Freddy's 2! Like the original Freedy, he is brown with a lighter-colored belly, ears and muzzle. His arms are bulky and extend in a similar fashion to the other nightmare animatronics, and his black bowler hat and bow tie are present. The hat looks worn and the wires are sticking out. He had sharp teeth and razor-sharp claws, and shiny yellow eyes, which gave him a more frightening appearance than his original opponent. The teeth are red-tinted at the end, like Nightmare Fredbear's. His body shape is slightly different from Freddy's as well, being much more sharp-edged and flat, with the head being much taller and more narrow than any of the other Freddy counterparts.

Funtime Freddy is a circus-themed version of Freddy Fazbear, who first appeared in Five Nights at Freddy's: Sister Location. He was also one of the artists in Funtime Auditorium, which is located at Circus Baby's Entertainment and Rental east of the venue (although he did not appear in the aforementioned auditorium). The other is Funtime Foxy. Funtime Freddy's design is very similar to Withered Freddy from Five Nights at Freddy's 2, with a metal suit, blue eyes, thin eyebrows, and a purple-striped bowler hat (similar to Toy Freddy's hat), a black bow tie, and two black buttons. On the chest, there is a set of human-shaped teeth. He is an energetic animatronic bear who loves to entertain children but is secretly a psychotic, deranged, and sadistic man who laughs with glee when he tries to kill his victims and has fun torturing them.

Molten Freddy is the remains of Ennard, controlling the consciousness of Funtime Freddy. He first appeared in Freddy Fazbear's Pizzeria Simulator as one of the four main villains. Molten Freddy is very similar to Funtime Freddy from Five Nights at Freddy's: Sister Location. However, unlike Funtime Freddy, he has a blocky jaw and a black nose with nostrils, and Molten Freddy is silver and rusty instead of white and purple. On closer inspection, the lower half of his body is simply a jumble of discarded parts such as wires and eyes, with no stirrup limbs at all. At Ultimate Custom Night, during his jump scare, several wires appear to be sticking out of his shoulders. Not sure why this happened. As with Funtime Freddy, his voice tends to malfunction when he speaks. His lines continue to have a birthday party theme.

Rockstar Freddy is one of four main animatronics designed by William Afton's former business partner Henry Emily for locations in the Pizzeria Simulator and is the mascot for the new Freddy Fazbear's pizzeria. He first appeared in Freddy Fazbear's Pizzeria Simulator as one of the many products available for purchase. Overall, Rockstar Freddy's appearance appears to be a combination of previous Freddy counterparts, as well as some new elements. His upper head looks similar to Toy Freddy's, with his jaws separated but connected at the top with a metal bar, similar to Nightmare Freddy or Withered Freddy. he holds his metallic purple microphone in his right hand. He has white sclera, sapphire blue iris, and black pupils. His kneecaps are also rose-red. rockstar Freddy, as quoted in his Ultimate Custom Night, is shown to have no real personality and appears to be an entertainment robot that accepts tokens.

Glamrock Freddy, the only animatronic in the pizzeria that won't be corrupted by Vanny's power, first appeared in Five Nights at Freddy's: Security Breach as a sidekick and ally to player Gregory. Glamrock Freddy is based on the original Freddy Fazbear as a base, with a punk-themed design reminiscent of the 1980s. His designs somewhat resemble a jaguar or lion rather than a bear. Glamrock Freddy was originally introduced as a nerdy, straightforward entertainer. Unlike other animatronics in the FNaF franchise and his previous iterations, Glamrock Freddy is generally a friendly, honest and easygoing personality, and actively assists and protects Gregory, even allowing him to hide in his stomach to prevent other animatronic devices from finding him. Despite being a robot, he is very sentient, not lacking in emotion, and even seems to obey a code of ethics, perhaps deliberately designed to be a good example for young children.
