Though less common in literature than evil stepmothers, there are also cases of evil stepfathers, such as in the fairy tales The Gold-Bearded Man (in a plot usually featuring a cruel father) and The Little Bull-Calf. One type of such tale features a defeated villain who insists on marrying the hero's mother and makes her help him trick the hero and so defeat him. Such tales include The Prince and the Princess in the Forest and The Blue Belt, although the tales of this type can also feature a different female relation, such as the stepsister in The Three Princes and their Beasts.
