Typhon.
The youngest son of Tartarus and Gaia, Typhon (Typhoeus) was a monster with one hundred dragon-shaped heads, each of which uttered a different bestial sound. Born after Zeus defeated the Titans, he was often considered a Giant because he, too, was an extremely powerful being who did battle with the gods. According to Hesiod, Zeus attacked Typhon with his thunderbolts, then cast him into Tartarus. Apollodorus relates that Typhon initially succeeded against Zeus, stealing his1 thunderbolts, cutting out his sinews, and throwing him into the Corycian Cave. The god was rescued by Hermes and Aegipan, who restored his strength. Zeus then defeated the monster and buried him under Mount Aetna; according to Pindar, Ovid, and Aeschylus, Typhon was the force behind that volcano. To Hesiod, he was also the source of the storm winds (typhoons) that cause shipwrecks.
