Typhon

In Greek myth Typhon was the youngest child of Mother Earth, the largest monster ever born.

From the thighs down he was nothing but coiled serpents, and his arms which, when he reached them out reached a hundred leagues in either direction, had countless serpents' heads instead of hands. His brutish ass-head touched the stars, his vast wings darkened the sun, fire flashed from his eyes, and flaming rocks hurtled from his mouth. When he came rushing towards Olympus, the gods fled in terror to Egypt, where they disguised themselves as animals: Zeus becoming a ram; Apollo, a crow; Dionysus, a goat; Hera, a white cow; Artemis, a cat; Aphrodite, a fish; Ares, a boar; Hermes, an ibis and so on. - The Greek Myths, Robert Graves, 1955

Project Typhon was the Goblin plan to create a god-destroying construct based loosely on this concept.
