Gorgos

Gorgos was the home planet of the Gorgons, located 100,000,000 light years away from Earth.

At some point in Earth's remote past the Gorgons developed technology for travelling between worlds by Transdimensional portals. They created a portal to Earth and three Gorgons crossed through, entering Greek mythology. After thousands of years, the last of the three attempted to bring the rest of its kind through so they could become as one with humanity and take over Earth. However, Maria Jackson closed the gate.
