Mangle is shown to be aware of the fact that they are in severe disrepair. Their voice uses several different pitches at once while also sounding somewhat distorted. They often speak in a somewhat mocking or sarcastic tone, mostly when teasing the user. They also seem traumatized by the experience of being disassembled repeatedly by children in Kid’s Cove. Their sanity seems to destabilize whenever their body parts fall off of what remains of their body.
