The Mangle

The Mangle is a Toy Animatronic introduced in Fnaf 2

Background
Mangle used to be one of the animatronics in the Freddy Fazbear's Pizza in FNaF 2. However, the toddlers constantly rip them apart piece by piece, forcing the staff to reassemble them every time. Eventually, the staffs decided to make them a "take apart and put back together" attraction for the kids to mess around with. They were also dubbed as "Mangle" due to this reason.

Power Chip
Falling Apart - The Mangle can dismantle itself into many parts to avoid damage. However, these broken parts are significantly weaker, and if they are broken, Mangle will take damage equal to how big the piece was.

Overcharge
Let's Play Take Apart And Put Back Together - The Mangle rushes a single opponent and summons ghost-like children to take them apart and mess them up for massive damage before returning them to normal. This has a chance to backfire and target Mangle.

Trivia

 * Out of all of the animatronics, Mangle seems to be in the worst state of disrepair - to the extent that they are a nearly costume-less endoskeleton.
 * Mangle may have two endoskeleton heads, if not two full endoskeletons. Upon close view of the suit head, the secondary pair of teeth and white pupils of a typical endoskeleton are visible, but another endoskeleton head that is exposed can be seen alongside it, sporting Mangle's missing left eye.
