Mangle

Let's all just use gender-neutral pronouns for this one, OK? (No really, nobody has definitive proof. Until we get 100%, undeniable proof that this thing is male, female, or neither, we're just sticking with a simple "it". No arguments, no spiteful users, no yelling at each other. You may think that Mangle is male, and I can respect that, but Scott hasn't confirmed it. Also, people reading this are going to be pretty confused with us right about now. So, you, yes you, are going to accept that I think that we shouldn't be using gender pronouns.)

Mangle
Mangle is an animatronic in Ultimate Custom Night and was a main antagonist in FNaF2.

Appearance
Mangle is a white dismantled fox with red cheeks, white feet, yellow eyes and a red bow tie. Its body is completely gone, revealing all of its endoskeleton. Only one eye is still intact, the other is on the endoskeleton head.

Mechanic
Mangle: Mangle makes his way through the vent system, but unlike the other animatronics in the vents, once he reaches the vent to your office he will never leave, and will enter your office the moment the vent door opens. The only way to stop her is to use the vent snare, which can only be active in one place at a time, forcing you to keep track of Mangle's location in the vent's to ensure that the correct vent snare is active. Once in your office, Mangle will hang from the ceiling creating audio disturbances before eventually dropping down to jumpscare you.

Strategy
Mangle can only be stopped by the vent snare, meaning that in less chaotic nights, you should check the vent radar to make sure Mangle isn't past the three nodes where you can set vent snares. If you manage to stop Mangle, you will hear the audio that indicates you have blocked an animatronic and you will gain one fazcoin.

Voice Lines
"Don't be afraid, soon you'll look just like me... Beautiful!"

"Now I get to play take apart and put back together! You won't feel a thing..."

"I wanted to wait until just the right moment to drop in!"

"It's so much more fun hanging out in here with you..."

"He's here, and always watching, the One you shouldn't have killed."
