The Mythos Arc opens with disasters all over the world and sightings of what seem to be the reincarnations of the Greek Gods of Mount Olympus.

The 00 cyborgs track the gods down to their island home in Greece, but 009 is defeated by the fiery Apollo.

The cyborgs discover the true nature of the reborn Greek gods shortly before Artemis is murdered, a crime 009 is blamed for.

The Greek gods make a last stand against the 00 cyborgs, while Dr. Gaia, a Black Ghost survivor, tries using their generator to destroy the world.
