Six

Six is the protagonist villain of the 2017 video game Little Nightmares.

History
Not much is explained about Six' backstory or situation in general. In the beginning of the game, she awakens deep in the bowels of a ship and starts to search for an exit. While traveling through the ship's innards, Six is pursued by deformed, sinister creatures who appear to intend to eat her. After evading them again and again, killing one of them by dropping a heavy door onto him, Six suddenly climbs to a lighter part of the ship where it is revealed that the ship is in truth a restaurant.

Throughout the game, Six suddenly starts having episodes of weakness due to enormous hunger. The weakness only leaves when Six eats meat that can be found nearby, However, despite initially only eating sausages or steaks, Six eventually starts attacking one of the small creatures living hidden on the ship when it tries to hand Six a sausage to still her hunger. Instead of eating the sausage, Six throws herself onto the creature, bites into its neck and feasts on its flesh, revealing that Six is in truth no better than the rest of the restaurant's patrons. Six continues her way through the ship, eventually confronting the ship's owner, the Lady. After defeating the Lady in battle, Six starts feeling hunger again and walks towards the defeated Lady, biting into her neck, killing her and feasting on her flesh as well. Six is then suddenly swarmed by a dark energy which incarnates in her. With this newfound power, Six heads back into the gast rooms where the patron's are still feeding. Using the sinister power, Six murders each and every one of them as she heads to the exit, eventually leaving the ship and stepping into the outside world.
