- "In this classroom, in this school, I am God!"
- — Principal Agatha Trunchbull, headmistress of Crunchem Hall Elementary School.
Principal Agatha Trunchbull is the main antagonist in the book, movie, and musical titled "Matilda." - a horribly abusive head mistress who acts more like a tyrant than a tutor. She is a brutal woman who took the idea of a control freak to the most extreme: an incredibly violent bully.
At school the next day, Matilda gives Miss Honey her doll and demonstrates her powers to her. Miss Trunchbull arrives, and tells Miss Honey she will be teaching her class. Miss Trunchbull orders the class to stand at the front of the room and holds up Matilda's ribbon, asking who it belongs to before throwing it to the floor and spitting on it when no one comes forward. In spite of this, Miss Trunchbull seems to be fully aware that the ribbon is, in fact, Matilda's. Miss Honey tries to defend Matilda, but ends up revealing her secret to the whole class by calling Miss Trunchbull "Aunt Trunchbull". Matilda then puts her plan into action. While the other children are reading, she uses her powers to levitate a piece of chalk and writes a ghostly message on the blackboard supposedly from Miss Honey's father, accusing her of killing him. It says, "Agatha, this is Magnus. Give my little bumblebee her house and her money. Then get out of town. If you don't, I will get you. I will get you like you got me. That is a promise."
Matilda then makes two erasers attack Miss Trunchbull, causing her to faint. Once she recovers, she throws a boy out the window, but Matilda causes him to fly back in, and she sends Miss Trunchbull crashing into a globe which Matilda magically spins around before Miss Trunchbull is sent flying off into the corner. She next charges towards Lavender, but she crashes through the door after Matilda's powers raises her off the floor. The rest of the children in the school grab their lunch boxes, and pelt Miss Trunchbull with the contents while chasing her. Miss Trunchbull flees from the school, quickly gets in her car and drives off, and is never seen or heard from again.
