Typhon

Youngest child of Earth and Tartarus (Hesiod) or of Hera alone (Homeric Hymn to Apollo), a hundred-headed fire-breathing monster who fought Zeus for the rule of gods and men and was blasted with the thunderbolt and cast into Tartarus or under Etna. Father, by Echidna, of Cerberus, the Hydra and Orthus. The Greeks also used his name for the Egyptian Set.
