The Greek goddess born fully grown and armored from the head of Zeus is Athena. She represents wisdom, warfare, and strategic battle. Athena’s unique birth came after Zeus swallowed her pregnant mother, Metis, fearing a prophecy that their offspring would be more powerful than him. She is often depicted with a shield and helmet, showcasing her warrior aspect while also being associated with crafts and the arts. Athena holds a significant role in various mythological stories, including the defense of Athens and her involvement in the Trojan War.
