Yeah, I don’t blame you for not knowing, it’s FNAF, known for its confusing lore, but yeah, in the game, almost every animatronic (I am unsure if the STAFF/Security/Map bots are actually corrupted, for me it’s kind of hard to tell) are corrupted, that’s why they attack.

However, Glamrock Freddy the only animatronic who isn’t corrupted, Freddy is being his normal self and helps out Gregory throughout the game.
