Yzma

Yzma is the main antagonist from the Disney film, The Emperor's New Groove. She was the former adviser of Kuzco, before she was fired by him for doing stuff without his approval. She vowed revenge by making a potion to kill him, but instead the potion turned Kuzco into a lama. She orders her assistant, Krunk to get rid of him. She soon finds out that Kuzco is alive and the two start to hunt for him. During the climax, Yzma is turned into a cat and tried to get the human potion before Kuzo could get it, but she failed and was forced to take part in Kronk's Junior Chipmunk classes.
