The Goose Girl
In some tales, the false hero appears early, and constitutes the main obstacle to the hero. These include "The Goose Girl" where a serving maid takes the princess's place, and makes her a goose girl, "The White and the Black Bride" where the stepmother pushes the bride into the river and puts her own daughter in her place, and "The Lord of Lorn and the False Steward", where the steward robs the young lord of Lorn and passes himself off as him, with the true lord serving a shepherd.
