Foxy, one of the four main antagonists in Five Nights at Freddy's, is a discontinued animatronic Pirate Fox entertainer who lives in Freddy Fazbear's pizzeria. Foxy is a stereotypical pirate who often speaks pirate slang with a pirate accent. One of his lines also suggested he might be claustrophobic. He is a large animatronic fox with dark red, tattered fur. He has yellow eyes, red eyebrows, and three strands of hair on top of his head. He has a hook in his right hand, and his left has worn down to the endoskeleton. He also wears a blindfold that folds over his right eye, although he is usually seen over his eye rather than covering it. Unlike a typical fox, Foxy has no tail. Like all other Fazbear characters, Foxy has a set of teeth. However, Foxy's teeth appear to be the sharpest of all animatronics, similar to real canines, while other animatronics have teeth that resemble human dentures or herbivorous teeth. It's also worth noting that, in keeping with the pirate theme, he has a few gold teeth and seems to be missing some too, but that's probably because he needs repairs.

Phantom Foxy is a hallucination of a burnt and ravaged Foxy that first appeared in Five Nights at Freddy's 3. Phantom Foxy has no eyes, instead, he has a white pupil in his left eye socket. His right forearm and hook are gone; the same arm can be seen in a box full of parts in the office. Phantom Foxy's mouth is always open, and even when he performs jump scares, part of his torso is gone, only the endoskeletal spine and wires. Unlike previous appearances, his blindfolds no longer flip up. Phantom Foxy also appears to be charred or burnt, possibly foreshadowing the agency's incineration. In Five Nights at Freddy's: Help Wanted, the Phantom Fox has a completely different appearance. He now uses the classic fox model from Five Nights at Freddy's and has no blindfolds and calves that keep his feet separate from his body. On closer inspection, he doesn't have eyebrows either.

Nightmare Foxy is a nightmare variant of Foxy, a taller, crimson, withered version of the original Foxy that first appeared in Five Nights at Freddy's 4. He had a severe tear in his lower body, and parts of his abdomen, chin, and head were lighter in color. His left hand is designed much like Springtrap and other Nightmare animatronics, and his right hand is replaced by a sharp metal hook. Like all other Nightmare animatronics, Nightmare Foxy's head appears to be split in two. Half of his muzzle is completely gone, revealing the metal frame underneath. He has a square black nose. The top half of his eye sockets are wide, the material above the orange metal eyes is completely decomposed, and a large crack has appeared on the upper right side of his face. Most of his ears are also missing. Nightmare Foxy is portrayed as a cruel and menacing animatronic who only wants to hurt his victims, making him the exact opposite of his original character, Foxy.

Grimm Foxy first appeared in Five Nights at Freddy's: Help Wanted's DLC mode and is one of two new nightmare animatronics introduced in the mode, the other being Dreadbear. From his multiple renderings and official art, Grimm Foxy appears to be playing the role of "Jack-O-Foxy". He is a large bipedal animatronic fox with red-orange fur and an overall structure similar to that of the Nightmare Foxy. Tears and tears were all over his suit, and most of the damage was on his torso. Similar to other Halloween-themed nightmare animatronics, he lost his endoskeleton head and had a bright orange glow from inside the suit. Unlike Nightmare Foxy, Grimm Foxy kept his eye patch and the tops of his eye sockets intact, making him look even angrier. As a visual aesthetic, flames pour out of him whenever he walks or runs. Another extra detail is the black spikes sticking out from his shoulders. Unlike Jack-O-Bonnie and Jack-O-Chica, Grimm Foxy has fire on him.

Funtime Foxy is a circus-themed version of Foxy that first appeared in Five Nights at Freddy's: Sister Location. The entire body of Funtime Foxy is covered in segmented lines, some of which are grey. They also possess a long, bushy tail that resembles a common fox. Like many of Foxy's peers, they have yellow-orange eyes. There are also three tufts of fur on their heads. They have a pink nose with three small purple freckles on each side and a black nose. They have pink inside their ears, around their eyes, and at the tip of their tails, and pink circles on their cheeks. In-game behavior suggests that Funtime Foxy is a silent, introverted animatronic who, unlike other animatronics from Sister Location, prefers to be alone. Funtime Foxy has a large speaker in the middle of his chest, so his voice sounds very loud like a person is speaking on a megaphone, and he has the ability to mimic the voices of other adults.

Rockstar Foxy is another redesigned version of the original Foxy that first appeared in Freddy Fazbear's Pizzeria Simulator. Unlike his other Foxy counterparts, Rockstar Foxy appears to be fully restored, his eyes are dark yellow. He also has darker red on his kneecaps, shoulders, and eyebrows. There are also four tufts of "fur" on the top of his head. Additionally, Rockstar Foxy kept the metal hook on the right arm and replaced the left leg with a brown dowel leg. Unlike other rock star animatronics, he doesn't have rosy cheeks. Like other rock star animatronics, Rockstar Foxy has a gold star button on the chest. He plays a black accordion with lilac tones and keyboards with white and black tones. Rockstar Foxy shares many of the same character traits as the original Foxy. In situations where he is about to kill the player instead of helping them, he will warn them of their impending death instead of killing them immediately or getting angry.
