The son born against the father's decree
Chief Shemwindo ordered his wives to bear only daughters and kill any son, yet one wife gave birth to Mwindo, who emerged already speaking, walking, and carrying a scepter from her middle finger. The father repeatedly tries to destroy him (burying him, sealing him in a drum thrown in the river), and the whole epic is the hero surviving these attempts, pursuing the father even into the underworld, and ultimately confronting him.
