Formerly a Hogwarts professor who, in the present, has aligned herself with Voldemort. Though Umbridge previously seemed to love power for power's sake more than she loved Voldemort's ideology, Voldemort does give her the opportunity to become powerful through exploiting and abusing those she hates and fears, such as Muggle-borns, half-blooded wizards, and other beings who aren't thought of as being entirely human, such as werewolves. Though she is a cruel and terrifying villain, her appearance and mannerisms paint an opposing picture: she's short, toad-like, and loves pink, bows, and garish kittens. Her voice is high and girlish, and her Patronus is a fluffy cat. Though Harry has always loathed her, he hates her even more when he discovers that she's using Mad-Eye Moody's magical eye to spy on underlings from her office at the Ministry.
