The Mangle is a multi-headed amalgamation of robotic parts that was accidentally created when an animatronic kept falling apart at a restaurant but became a character used by the company. Its gender is debatable (and it is debated) but its voice is feminine, and it also has another, deeper voice for its second head (You can just record the lines normally and I'll make the second voice in editing). Its voice should be deep and calm. It is cruel and sadistic and seems to enjoy mangling people (although that's actually not where the name comes from). It's a robot, and its voice will be robotic (you don't need to do the editing yourself though), but it's not monotone.
