Perseus

In Greek mythology, Perseus was the son of Danaë and Zeus. His grandfather, King Acrisius, fearing a prophecy that Perseus would kill him, locked Danaë and Perseus in a box and cast them into the sea. They were found on the island of Seriphos by a fisherman named Dictys.

As a young man, Perseus was sent by King Polydectes to slay the Gorgon Medusa. With gifts from the gods—a sword, winged sandals, an invisible helmet, and a shield—he decapitated Medusa using the shield as a mirror. Her blood gave birth to Pegasus. On his journey, Perseus turned the giant Atlas to stone and saved Andromeda from a sea Legendary Creature, marrying her.

Back in Seriphos, Perseus used Medusa's head to turn Polydectes and his soldiers to stone before giving the head to Athena. Perseus later killed his grandfather Acrisius by accident with a discus, fulfilling the prophecy.
