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.

In the 2017 TV series, Algernon Rowan-Webb is portrayed by Philip Martin Brown, debuting as a frog in the pilot episode, where he indirectly helps Mildred recreate a levitation spell to warn the other students about Agatha Cackle's attempted coup of the school. His status as a human is exposed in the fifth episode "Pond Life", which reveals that he was actually the first wizard to teach at Cackle's, and had a romantic relationship with Miss Bat, but was turned into a frog by spell science teacher Miss Gullet so that she could take the job herself. Once returned to human form, he becomes the spell science teacher himself, although he retains an elongated tongue for use in catching flies.
