In Greek mythology, Zeus is the king of the gods and also the god of the sky and weather, although his role as the foremost god generally eclipses his specific association with weather except for his wielding thunderbolts as a manifestation of his anger.
Zeus is one of the eight sons of the Titan Cronus, and led the rebellion against him which established the dominance of the Olympian gods. He is married to his sister Hera, although the marriage is plagued by Zeus's numerous extra-marital affairs with both gods and mortals. When conducting affairs with mortals, Zeus typically appears to them in disguise, for example as a bull or a swan. He has many children, including major gods and goddesses such as Hermes, Ares and Athena, and the demigods Perseus and Heracles.
