Hercules is the son of Zeus, king of the Olympian gods, and Alcmena. Zeus seduced Alcmena in the guise of her husband, King Amphitryon of Troezen. Thanks to Zeus's enchantment, Hercules was born with the potential for extraordinary superhuman strength, which he first displayed before he was even one year old by strangling two serpents which attacked him (sent by Hera). Hercules had many notable adventures in ancient times. He sailed with the Argonauts (with them he may have battled the Akaana), faced the Hydra, saw the death of Medusa, and defeated Antaeus.
