Nemea is the town famous for being beset by the Nemean Lion. Hercules slew the lion and kept its skin (Hercules in the Underworld).
Later, Nemea's government was on the verge of collapse. King Trancas sent financial aid to the government with Hercules. Nemea was the home base for the gangster Zeno. When Iolaus briefly lost his memory and parted with Hercules he travelled to Nemea and found himself in the employ of Zeno (HTLJ "Hero's Heart").
