A son of Lycus (brother of Nycteus), Lycus appears in Euripides's Heracles. Originally from Euboea, he seized power in Ancient Thebes (Boeotia) by killing Creon, who at the time was regent for the son of Eteocles, Laodamas. Lycus mistreated Creon's family, throwing them out of their house and depriving them food and clothing. However, Creon was the father-in-law of the hero Heracles, who returned unexpectedly to Thebes and slew Lycus. Laodamas succeeded him as king.
