Баба-Яга
Similar to a witch, Baba Yaga is a supernatural being (or one of a trio of sisters of the same name) who appears as a deformed or ferocious-looking old woman. In Russian fairy tales, Baba Yaga flies around in a mortar, wields a pestle, and dwells deep in the forest in a hut usually described as standing on chicken legs. Baba Yaga may help or hinder those that encounter or seek her out and may play a maternal role and has associations with forest wildlife. According to Vladimir Propp's folktale morphology, Baba Yaga commonly appears as either a donor, villain, or may be altogether ambiguous.
