An unnamed protagonist appears in Five Nights at Freddy's 4. He is controlled by the player, they have little-to-no detailed information and were never actually seen in the game, except for one child in the end-of-night minigames.
Main Gameplay
The child using their flashlight to look around in the bedroom.
The child resides in their bedroom and must look after the nightmare animatronics from his surroundings to survive in all seven nights, from 12 to 6AM. He has fair hearing, especially when considering Nightmare Bonnie and Nightmare Chica's quiet breathing.
End-of-Night Minigames
Unlike other protagonists of the game, his physical appearance is fully viewed. He has a fairly light skin tone with his face constantly stained with tears. He wears a black shirt with two lone gray stripes on it, and blue short trousers, an outfit which he wears for 6 days straight. He has constant black eyes and dark brown hair.
The end-of-night minigame after Night 5 reveals him to be the bite victim of '83, after being pushed into Fredbear's functioning mouth by his older brother and his gang from the diner.
In Five Nights at Freddy's: Sister Location, the Breaker Room's map reveals that the Five Nights at Freddy's 4 locations (the house during main gameplay, end-of-night minigame areas, and Plushtrap's hallway) are separated in different places. This may suggest that there are multiple protagonists.
