Mangle is a fascinating one indeed. Mangle has two perspectives, one being very playful and full of energy and gets very flamed up when a piece of her drops off her. She also has another head, which is the other perspective, and this other part goes on the negative side of things and gets all rude. The first voice should have a normal and deep pitch and should also be distorted and bit-crushed (8-Bit), while, the other should just be a Flanger.
