Edith Anthrope is the school secretary at Jerome Horwitz Elementary School. Her name refers to "misanthrope", while her full name is a pun on "eat it and throw up."
Like most of the teachers in Jerome Horwitz Elementary School, Ms. Anthrope is not very nice. She is the school secretary. Her name is a pun on the word 'misanthrope' Captain Underpants and the Perilous Plot of Professor Poopypants, when she wears a crop top on a school field trip. Her usual way of hiding her belly button is by covering it with clothing, which has little effect, since her belly button sticks out so much that it is very visible even underneath the clothing. She is probably so hateful toward George and Harold for the sole purpose that, in every comic book they made with her in it, they purposely drew a bulging outie belly button to further humiliate her. She is currently in jail due to the events in book eleven.

The First Epic Movie
Ms. Anthrope shows up in Captain Underpants: The First Underpants Movie. In the film, she is depicted as being even fatter than in the book. She first shows up entering her office when George and Harold tried infiltrating it to get Melvin's turtle. To distract her, George calls her and using a voice mimicking a game show host's, asks her to please hold if she would like to win $1 billion. Anthrope gullibly buys it and being so excited about it stays on hold and stays frozen that way for the rest of the movie.
In a mid-credits scene, George and Harold find that she's been on hold for the whole movie. George decides to call her again, and Anthrope gets so surprised that she accidentally drops her phone perfectly into the position of hanging it up. Realizing she "lost" her chance to win $1 billion, she screams and throws a fit of rage. Unsurprisingly, George and Harold don't feel sorry for her at all, they just make her the theme of their next comic book, "Attack of Stuck on Hold Woman".
