The twin brother of Heracles and the son of Amphitryon and Alcmene.
Unlike his brother Heracles, Iphicles was not a son of Zeus, and so had none of his brother's extraordinary powers. His parents realized this early when Hera, jealous of Zeus' infidelities, sent down two serpents to kill the helpless babies. Iphicles screamed at the sight of the serpents, but Heracles clutched the serpents by their throats, strangling the great snakes.
Iphicles accompanied his brother on several occasions. He eventually died while fighting the Moliones with Heracles.
