Typhon was known as the "Father of all monsters"; his wife Echidna was likewise the "Mother of All Monsters."
Typhon was described as one of the largest and most fearsome of all creatures. His human upper half reached as high as the stars. His hands reached east and west and had a hundred dragon heads on each. He was feared even by the mighty gods. His bottom half was gigantic viper coils that could reach the top of his head when stretched out and made a hissing noise. His whole body was covered in wings, and fire flashed from his eyes.
The Sphinx was sent by Hera to plague the city of Thebes. She was the most brilliant of Typhon's children, and would slay anyone who could not answer her riddles (possibly by strangling them). When Oedipus finally answered her riddle, she threw herself into the ocean in a fit of fury and drowned.
The Nemean Lion was a gigantic lion with impenetrable skin. Selene, the moon goddess, adored the beast. Heracles was commanded to slay the Lion as the first of his Twelve Labors. First, he attempted to shoot arrows at it, then he used his great club, and was eventually forced to strangle the beast. He would then use the Lion's own claws to skin it, whereupon he wore its invulnerable hide as armor.
Cerberus, another one of Typhon's sons was a three-headed dog that was employed by Hades as the guardian of the passage way to and from the Underworld. According to Hesiod, he was the son of Orthrus and Echidna.
Orthrus, a fearsome, two-headed hound. According to Hesiod, he mated with his mother, Echidna, to sire Cerberus, the Nemean Lion, the Lernean Hydra, the Sphinx and the Chimera. Orthrus, and his master, Eurytion, son of Ares and the Hesperid Erytheia, guarded the fabulous red cattle of Geryon. Both were slain, along with Geryon, when Heracles stole the red cattle.
Ladon was a serpentine dragon, known as a drakon. According to Hesiod, Ladon was the son of Phorcys and Ceto, instead of Typhon and Echidna. Regardless of his parentage, Ladon entwined himself around the tree in the Garden of the Hesperides at the behest of Hera, who appointed him the garden's guardian. He was eventually killed by Heracles.
The Lernaean Hydra, another one of Typhon's daughters, terrorized a spring at the lake of Lerna, near Argos, slaying anyone and anything that approached her lair with her noxious venom, save for a monstrous crab that was her companion.she was originally thought to have nine heads,and any neck,if severed,would give rise to two more heads.her ninth head was immortal. She and her crab were slain by Heracles as the second of his Twelve Labors - he cut off her heads and burnt the neck so that she could not regenerate,and crushed her ninth head under a rock. (the crab being accidentally crushed underneath Heracles' heel).
Typhon's last child was his daughter, Chimera. Chimera resembled a tremendous, fire-breathing lioness with a goat's head emerging from the middle of her back, and had a snake for a tail. She roamed the ancient kingdom of Lycia, particularly around Mount Chimaera (possibly near Yanartaş), bringing bad omens and destruction in her wake, until she was slain by Bellerophon and Pegasus at the behest of Iobates.
Typhon was defeated by Zeus, who trapped him underneath Mount Etna.
