Madame Lefrere is an unseen character that only appears in Rodrick Rules. She is a French teacher who selected pen-pals for her students. Greg marked off boxes for a female penpal, however Madame told him that he had to get a French boy who is the same age as him, so Greg was paired with Mamadou Montpierre. Her name literally translates to "Mrs. The brother" in French. Due to her name and the fact that she is referred to as "Madame", she may be of French descent.
