Prometheus (voiced by Carl Reiner) is a good-natured Titan who stole fire from Olympus to give to humankind. He is depicted in song as having blonde hair, but when he is shown, he has wrinkled skin and gray hair. His punishment was to be chained to a mountain with a bird eating his liver every day. At night his liver would grow back, only to be eaten the next day. Surprisingly, the series left out Prometheus tricking the gods by giving a good-looking pile of meat to Zeus, but it was really the worst parts.
In "Hercules and the Prometheus Affair", Prometheus is freed by Hercules. Zeus sends all of the gods to search for him. The gods who are actually shown searching for him are Apollo, Demeter, Artemis, Ares, Poseidon, Hades and Zeus. Others like Hephaestus and Aphrodite are there when Prometheus is captured but not shown searching for him. Prometheus is mentioned in "Hercules and the Pool Party", where Hades mentions that there was a roast for him and he (Hades) sat next to the overwhelmingly mundane God, Trivia.
