Zeus is the king of the gods in Greek mythology. He appeared as a member of the Council of Nine in the Imaginationland trilogy. He gets killed when Imaginationland is blown up by a nuclear missile but gets revived when Butters reimagines Imaginationland as it was before the evil creatures burst out of the barrier.
Zeus has white hair, along with a white goatee. He wears the standard, white, Greek toga, and golden wrist bands. He also has a muscular build and appears to be taller than the average South Park character.
Despite being in the Council of Nine, he seems cowardly, wanting to run instead of fight the evil imaginary characters in the Imaginationland trilogy. He had to be coerced into fighting by the other council members.
