Older Brother

Big Brother (or "Foxy Mask) is a Former antagonist in Five Nights at Freddy's 4, appearing as the main antagonist of the minigames. He is the protagonist's abusive older brother, and is the one who caused the child's accident. Nightmare Foxy represents him in gameplay.g Brother is only seen in the minigames, particularly on the second, third, fourth and fifth nights. His role as the child's brother, and not his father, is revealed on Night 5.

He hates his little brother, likely due to him still being a child, and has apparently abused the child to the point of him crying all the time. Five days from the party, he locks his brother in his room, laughing sadistically from the outside. Fredbear seems unfazed by what Big Brother is doing, only asking what he has done "this time." Fredbear constantly tries to help the child avoid Big Brother, guiding him with his words.
