The Worst Witch
Mildred "Millie" Hubble is the protagonist of the series. She is a good-hearted, but bungling young witch-in-training, who never seems to get anything right. She is friends with Maud Spellbody and Enid Nightshade and has a strong rivalry with Ethel Hallow. It is Miss Hardbroom, her potions teacher, who calls her "The Worst Witch".
List of The Worst Witch characters
Miss Constance Hardbroom is the terrifying and extremely strict form-mistress of Mildred, Maud, Enid, Ethel, and Drusilla. She is tall, thin and bony with waist-length black hair which she keeps ""scragged into such a tight knot that her forehead looked quite stretched"". Miss Hardbroom favours Ethel Hallow but has the complete opposite attitude to Mildred Hubble. Miss Hardbroom is even terrifying enough to reduce any pupil to a gibbering heap with one word. Despite seeming cruel, Miss Hardbroom's soft side does come through on occasions, such as her ""brief flicker of friendliness"" at the end of "The Worst Witch Saves the Day" and her admitting her error of judgement in "The Worst Witch to the Rescue" after it is revealed that Ethel stole Mildred's summer project for herself, Maud noting in "The Worst Witch and the Wishing Star" that Miss Hardbroom's dislike of cheats means that Ethel will be under close watch.
