Gegenees

The Argonauts landed on the Propontis coast at a place called Bear Mountain, ruled by the young king Cyzicus of the Doliones. Cyzicus was hospitable and warned them about the creatures on the mountain's interior — the Gegenees, six-armed giants born from the earth itself.

While Heracles stayed to guard the Argo with a skeleton crew, the rest of the company climbed the mountain to explore. The Gegenees attacked without warning, hurling boulders the size of carts. Each giant wielded six arms independently, throwing and grappling simultaneously, which made them horrifyingly effective fighters despite their crude tactics.

Heracles heard the commotion and opened fire with his bow. Arrow after arrow sank into giant flesh. The surviving Argonauts rallied and pushed the Gegenees back toward the cliffs. One by one the giants fell — some from arrows, some from spears, some toppling off the mountain's edge under the coordinated assault.

The battle was decisive. The Gegenees were wiped out, their bodies left where they fell. Bear Mountain was safe for the Doliones, and the Argonauts had proven they could handle threats beyond ordinary warfare.

The Gegenees belong to the "earth-born" category of Greek monsters — autochthonous creatures generated spontaneously from Gaia, existing before civilization and hostile to it. Their six arms mark them as belonging to an older, more chaotic order of creation, kin in spirit to the Hecatoncheires though far less powerful.
