Agatha Trunchbull

Agatha Trunchbull is the main villain of "Matilda" - a horribly abusive principal who acts more like a dark lord than a tutor, she is a brutal woman who took the idea of a control freak to the most extreme: an incredibly violent bully. Agatha thought nothing of literally hurling children vast distances and confining those who dared to oppose her into a medieval torture-device that resembled an iron maiden: her tortures were so extreme they could easily have been fatal (though by some miracle her victims always survived): thankfully the fearsome tyrant was toppled by Matilda's quick thinking and magical powers, who tricked her into believing she was being haunted by the ghost of her brother-in-law (who, it is implied, may have been murdered by Agatha in order to inherit his estate) - upon being convinced of this haunting Agatha fled, much to the pleasure of everyone she had been terrorizing. In a scene in the book, she rips a child's hair out. In the film, she breaks the same child's leg instead for not emptying his pockets fast enough.
