Mythical creatures and monsters
In Greek mythology, Ladon represents the invincible dragon. He was the son of the sea gods Forkyn and Keto.
His siblings were the three Graia (Eny贸, Pefr茅d贸 and Dein贸), the three Gorgons (Sthen贸, Euryale and Medusa), the nymph Tho贸sa and the sea monster Skylla. Other sources say he was the son of Typhon and Echidna.
Ladon had a hundred heads, spoke different languages, had great strength, and most importantly, never slept. Hera chose him to be the guardian of the golden apple tree in the garden of the Hesperides.
No one dared to challenge Ladon, not even Heracles. He needed three golden apples from the garden of the Hesperides, which were brought to him by the titan Atlas. Other myths state that even Atlas was afraid of Ladon, so Herakles shot the dragon with an arrow (through the wall).
