As revealed in TRTF: TDT, Foxy along with all of the other animatronics in the game, are all haunted by BFP, desperate for Mike Schmidt's attention so he can free him from his decades of torment and pain.
Foxy's appearance is directly from Five Nights at Freddy's, with the exception of his jumpscare, which is from Five Nights at Freddy's 2.
Foxy will begin moving after Chica leaves in The Office. He will then peek out of the curtain at Pirate Cove. Then he will leave the curtain, kneeling on the ground. Then he will move to the West Hall, then the office. The player must immediately put on the Freddy Mask when this happens, with a slight delay.
- An eyeless Foxy easter egg can be performed by clicking on Freddy's mouth in the first cutscene. Each time, it will play a honking sound. Once that it done 5 times, he will appear and everything else will disappear, and the game will crash.
- When this happens, the game tries to stop a scream sound, however, it is never played in-game.
Just like TRTF Classic, Foxy remains being haunted by BFP, who's desperate for someone to notice him so that he can be freed.
Foxy is a red fox animatronic. He has a pirate theme; this is indicated by his eyepatch, his hook and his legs looking like pants. He has a tan snout with a nose. His teeth are sharper than the other animatronics. His endoskeleton is rusty. He has two ears. Foxy appears to be fixed unlike his appearance in the main games.
Starting from Night 2 and onwards (just like the 1st game), Foxy will start in Party Room 2 (albeit off-camera). After that Foxy will then occasionally proceed to move into the East Hall, but most of the time after leaving Party Room 2 he will go straight into the office hallway. Unlike most of the other animatornics in the game, Foxy isn't actually fooled by the Freddy Mask. So if Foxy does ever get into the office, the player has to quickly flash your light at him instead to scare him off. If the player fails to flash their light at him, Foxy will instantly jumpscare the player.
- In The Return To Freddy's 2 Foxy seems to be fixed because of his debut appearence in Fredbear's Family Diner. Considering only the TRTF saga and the original Five nights at Freddy's saga, this is the only time that foxy is seen fixed, even considering the minigames from both sagas.
Foxy comes back once again, as a major antagonist in The Return to Freddy's 3 as well as being one of the main mascots of Fazbear Fantasy Land. According to TRTF: TDT, this version of Foxy is the same one that appeared in the previous game.
Foxy looks very decrepit. He is now black because of the lighting and looks burnt. His left ear is missing its suit. His arm and legs are ripped up. His left hand, his hook is larger than in TRTF2, his lower legs and his endoskeleton feet are exposed. Wires are poking from various places.
Foxy starts in CAM 11. If Foxy appears in the left hallway, the player must use the corrupt signal on the system panel to make him leave. However, you can briefly prevent him from moving at all by closing the CAM 11 door.
- When in the Office Hallway, he seems to be missing his nose and lower jaw. this may be an error
In a similiar fashion to both, Chica and Vigo, Foxy is now, completely inactive in The Return to Freddy's 4, as he is heavily implied to have not survived the destruction of Fazbear Fantasy Land. However, he isn't completely absent from the game. Foxy can now be seen as a dismantled suit prop in CAM 09.
Foxy has no other major appearences in TRTF 4, aside from a small Foxy plush that can be seen in CAM 04, in the Night 4 minigame, a child wearing a red shirt (who later possessed Foxy) can be seen, being murdered by Vincent. Other than that, Foxy has no other appearences throughout the game, now being replaced by Koly.
Foxy seems to retain his same exact model from The Return to Freddy's 3. However, his suit noticeably now appears to be noticeably lacking arms or legs, while only his head, ears and main body remain. His endoskeleton also appears to be noticeably gone (with the exception of his ears), now being supported by a long steel pole.
