Yzma

Yzma is a hideous old woman who wants to usurp the throne by murdering emperor Kuzco. She has a strong, but rather stupid henchman named Kronck. She appears in the Disney comedy The Emperors New Groove.

Plan
She originally planned to dispose of the emperor by turning him into a flea..."A harmless, little flea." Then she would put it in a box, put that in another box, mail it to herself, then smash it. But then she decides to poison him. This backfires when the potion meant to poison him was actually a potion that turns people into llamas.

Personality
Yzma's character in the series is seen to be malicious, but comically eccentric, often calling herself beautiful even though all other characters in the series consider her appearance revolting. She is a complicated thinker; an example given with her original plan to kill Emperor Kuzco. Her original plan involved her turning him into a flea, putting him in a box, putting that box into another box and then mailing that box to herself only to smash it with a hammer.

Yzma's character is described to be "scary beyond all reason". Yzma's color theme was stated to be purple, being that purple is a color often associated with evil. Purple is also a colour of royalty, showing Yzma's ambition to be an empress. Additionally, purple carries connotations of madness, alluding to her insane lust for power. Her character is also surrounded with animals like snakes and cats, which are considered to be signs of evil in numerous religions throughout the world.

Yzma is seen to have some knowledge in chemistry, as she accidentally uses extract of llama on Kuzco, thinking that it was poison.
