The scariest thing about the Five Nights At Freddy's games is not malfunctioning animatronics. Neither is it the bite of 87. The scariest thing about FNAF 1,2,3 and hopefully more, is the fact that you don't know who you are. Now, we know that the animatronics have dead children inside them (Freddy's child most probably a girl, judging by his laugh) there are even theories that they think they are playing a game of hide and seek, which the killer might've before he (know any female humans in the game?) killed them. Anyway, play FNAF 2 minigames and you'll see the 'bodies' scattered all around the pizzaria. Disturbing, right? It get creepier. You play the games through three night guards eyes; one of which may be the murderer. Also, in one of the mini game, there is a figure who fans have called "Purple Guy", or "Purple Man". He is holding what kind of looks like purple banana (lol), but could also be a phone; meaning he is "Phone Guy". It is unclear whether PG has actually been spotted in the real game, but rumor has it he can be found. Getting back to the murderer, many think that Purple Guy is the one responsible for the deaths, as in the mini games which feature the bodies, he appears. However, as stated before, a few believe that YOU are killer, which is even more creepy that PG, if you ask me.
