My FNaF Theories

The bite of 1987

Many people think that Foxy caused the bite of 1987. And who was the victim?

The victim:
The victim could have been YOU (aka Jeremy Fitzgerald, that character you are playing as)
YOU were probably bitten. And I'll tell you how I might know this..

Who did, done, do it?:
Mangle cause the bite of '87. She has a whole reason of WHY she did it.
As you may know, Mangle used to be a loving animatronic before all the kids decided to pull her apart piece by piece. The staff would usually have to put Mangle back together after every shift, but then they no longer bothered.
From then on, Mangle was a "take apart and put back together" attraction, as left by the staff. This could have led Mangle to either hate children, see the children as a possible threat or otherwise become unstable. That is the reason why SHE caused the whole bite drama.
Also, she has more of a chance of doing it. Her death screen is when she swing down from the ceiling and at your head, your FRONTAL LOBE! Yes, Foxy could have also done it, but what excuse has he got? Also, he wasn't used. He was in the parts and service throughout the time of the pizzeria.

Now this leaves me hanging, who was the victim? I bet it was YOU, because she swung down and bite YOU on the head!
Or possibly a child because she was either scared or angry that the kids would ruin her everyday.
