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.
Grand High Witch
The Grand High Witch is described as the most powerful being in the world and is the only one linking the secret societies of demonic witches that exist in various countries, as they are not allowed to contact each other. The Grand High Witch's headquarters is a great castle in Norway, where she has a magic money-printing machine and lives with large retinue of special Assistant Witches, tyrannically ruling over all the witches anywhere and plotting ever more harm to children everywhere. The current Grand High Witch, who is unnamed in the book but is known as Eva Ernst (Miss Eva / Miss Ernst) in the film, is described as "the most evil and appalling woman in the world."
