Nebula took Hercules and Iolaus to Sumeria, where the angry gods were leveling cities. To remedy the situation, King Gilgamesh took Hercules with him on a series of physical trials in a pyramid, where they retrieved a chalice of sacred nectar. But Gilgamesh betrayed Hercules by drinking the nectar and crushing the cup, becoming a disciple of the demon Dahak. Next, Gilgamesh tried to scarifice a warrior heart -- Nebula's. But Iolaus, who was in love with Nebula, saved her by taking the dagger himself. Hercules destroyed Gilgamesh, but he was too late for Iolaus, who died in his arms.
