Dolores Umbridge

Dolores Jane Umbridge is the Defence Against the Dark Arts teacher in Harry Potter and the Order of the Phoenix.

She is a short, squat woman described as resembling a large pale toad, with "short, curly, mouse-brown hair".

She speaks with a quiet, childish, high-pitched voice, and loves kittens, chocolate cakes, biscuits, tea and other cute things, decorating her office with related paraphernalia.
She has a tendency to speak to people she feels are her lessers in a very condescending tone, as if they are simpletons or very young children.
