Miss Agatha Trunchbull, also known simply as "the Trunchbull" or "Miss Trunchbull," is the fictional headmistress of Crunchem Hall Primary School (Crunchem Hall Elementary School in the 1996 film) and main antagonist in Roald Dahl's book and the film, Matilda, said to look "more like an eccentric and rather bloodthirsty follower of the stag-hounds than the headmistress of a nice school for children." She is a harsh, cruel educator and is later revealed to be the aunt of Matilda's teacher, Miss Jennifer "Jen" Honey.
