Kronos, Athena and Nereus appeared as Goa'uld in the Stargate franchise, which currently includes the Stargate movie, Stargate SG-1, Stargate Atlantis, Stargate Infinity and Stargate Universe.
Pelops and Ares are mentioned as reptilian System Lords and there are several planetary cultures encountered by SGC teams that have not strayed far from their Minoan, Hellenic or Roman roots.
According to the Stargate mythos the Goa'uld seeded humans throughout the galaxy to serve them as host bodies, slaves and the unknowing subjects of countless nefarious experiments.
Other Greco-Roman gods are hinted to have been Ascended beings with ties to the Ancients from the Pegasus galaxy who inspired our legends of Atlantis and Camelot.
