Cerberus

Hades’ three-headed hell-hound, Cerberus, guards the entrance to the Underworld. Cerberus is the offspring of Typhon and Echidna, who are children of Gaea. Thus, Cerberus is much more-fearsome than any normal hellish-hound. It is enormous, with superhuman Might and Fortitude, and sufficient Prowess to challenge the gods! Beware his powerful teeth, and take heed of the body that could withstand blows from Hercules.
