One night, while he was sleeping, Cacus, a monster born of Hephaestus (Vulcan), and stole some of his cattle. When Heracles woke up, he didn't notice any of the cattle missing until he heard mooing from a cave. He punched a hole through the cave, and put up to Cacus and his fire breathing, and got his cattle back.

He had one hundred dragon heads surrounding his own, as tall form the earth to the stars, and his wings stretched from east to west. He caused massive damage on Earth and Olympus. He was then put under Mount Etna where he still breathes fire.
