Freddy Fazbear

"Uh... Interestingly enough, Freddy himself doesn't come off the stage very often.  I heard he becomes a lot more active in the dark, though , so, hey, I guess that's one more reason not to run out of power , right? "

-Phone Guy, Night 2

Theories
Ok, I know this sounds crazy, but I think that freddy is a girl (The Game Theorists). If you speed up his laugh, it sounds like a girl. He (she), when he's(she's) moving around, doesn't go in the boys bathroom. He(she) goes in the GIRLS bathroom. Now, I don't think Freddy himself is a girl, I think the SOUL inside him is a girl. That's the reason he goes in the girls bathroom,  the girl inside him still follows the same rules she had to when she was alive, like no to going in the boys bathroom. I did get some of this info from The Game Theorists.

Controls
Freddy doesn't start moving around until night 3. He stays on the stage until then. After night 3, he starts moving around a lot. He stays in the dark most of the time, so you can only se his glowing eyes. If, you brighten up the image of him in the hallway/corridor,  you can see the entirety of his eyes, and maybe more. All the places you can see him are the stage, the dining room, the girls bathroom, the hallway, the end of the hallway, and at your door when you run out of power. Whenever you run out of power, he flashes his eyes at you while playing a song. After his song is finished, he slowly walks up to you in the dark, without you being able to see him, then he jumpscares you. The length of the song varies, and there is a chance that you can beat the night while the song is playing.
