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
There is also some inconsistency regarding Maud's surname. The 1998 TV series gave her surname as "Moonshine", but it is never referred to as this in the books; in fact Miss Hardbroom scathingly addresses her as Maud "Spellbody" in "The Worst Witch All at Sea". The 1980s Halloween television movie gave her surname as "Warlock". Later books, including "Fun with the Worst Witch" (2014) gave her surname as 'Spellbody' however.
