Theories and discussions are allowed but no arguing please

It’s mangle. They’re shown to supposedly bite you in their jumpscare, they were operational at the time, and they were always getting taken apart, giving them motivation to do such things.

And it could not have been one of the withered's because it was the toys who we scrapped at the end of fnaf 2, not the withered's.

yes

Yep
I seen the jumpscare before and it looks like Mangle's lunging directly toward your head

honestly? i'm thinking toy chica. it's shown that her beak go brrrrr

I was reading the FNAF wiki and they suspect it could have been either Withered Foxy, Mangle or Freddy himself
Withered Foxy and Mangle's jumpscares show that their jaws are going toward your head
And supposedly Freddy has handprints on his face
But those are just speculations

It could not have been Freddy or foxy, because the toy animatronics were scrapped, not the withers.

Mangle. 100%

Hah my mom's so old her teeth are more dull than your joke

Chain time?

yes
