◾Circus Baby is the leader of the animatronics, similar to Freddy from previous games, however her main objective is to devise a plan to escape the facility, rather than killing the Player.
◾ It's possible that when Afton's daughter was killed by The Original Circus Baby, her soul inhabited Baby's body alongside Baby's consciousness.
◾ On Night 1, the lights in Baby's stage area may have been intentionally turned off so the Player would be forced to shock and torture Baby repeatedly despite her behaving normally. This may be due to a grudge that William Afton had against her for killing his daughter.
