The name of the principal in the book Matilda, written by Roald Dahl, is Agatha Trunchbull. She is portrayed as a rather tyrannical and abusive headmistress who has little patience for children and loves to exert her authority with fear and intimidation.
Trunchbull’s character serves as a significant antagonist in the story, standing in stark contrast to the kind and nurturing Miss Honey, Matilda’s teacher. The way Roald Dahl presents Trunchbull enforces the theme of good versus evil, making Matilda’s triumph over her difficult circumstances even more satisfying for readers.
