List of The Worst Witch characters
Mildred Hubble is the titular character of "The Worst Witch" series. Unlike the other girls at Miss Cackle's Academy for Witches, she doesn't come from a regular witch family, but was given a scholarship which greatly impressed Miss Cackle. She is best friends with Maud Spellbody and Enid Nightshade. In "The Worst Witch", although inadvertently ruining a broomstick formation flying display when she was given a sabotaged broomstick, she saves the whole academy from Miss Cackle's jealous and rebel-ish identical twin sister Agatha Cackle, who was seeking to turn all the teachers and pupils into frogs. In the nick of time, Mildred turns Agatha and the rest of her fiendish coven into snails.
The Worst Witch
Miss Hardbroom is the fearsome deputy headmistress of Miss Cackle's Academy and the clear power behind the throne. She is Mildred's form mistress in first form and through various combinations of events continues to be her form mistress throughout the series. Tall, bony and sour-faced, she strikes fear into the pupils' hearts. "HB", as the girls refer to her, seems to have a particular resentment of Mildred. Miss Hardbroom frequently praises and rewards Ethel Hallow, and frequently rebukes Mildred in front of the other students. It is Miss Hardbroom who gives Mildred the title of "the worst witch in the school".
