Witches from the Volcano of Gloom
The Witches from the Volcano of Gloom are one of the few recurring enemies in the franchise, first appearing in My Little Pony: The Movie and later returning for the movie length My Little Pony 'n Friends story arc, The End of Flutter Valley. The mother is named Hydia and her daughters are Reeka and Draggle. All three have a strong dislike of sweets and traditionally "nice" things like sunny days. Hydia laments that Dream Valley used to be a gloomy haven for evil before the ponies came along. Fed up with her daughters' lazy incompetence, Hydia tasks her daughters with collecting the ingredients for The Smooze in The Movie and joins forces with a warrior bee race in The End of Flutter Valley.
Reeka has a unending appetite but is shown to have a decent grasp on magic despite the sisters' collective bumbling. Draggle is a klutz with limited magic but has a capacity for kindness and teamwork in some situations, commonly calling Hydia "Mom" despite her objections.
