Dark Science Empire Deathdark (暗黒科学帝国デスダーク Ankoku Kagaku Teikoku Desudāku) was an ancient empire which reigned for millenia.
Since the time when iron was discovered in ancient Turkey, Deathdark has existed, manipulating the world from the shadows for the purpose of destroying humanity, playing a role in the destruction of many advanced civilizations in the ancient world. They continue to gain access to new technology either through self development or through theft of new developments by humanity for their own usages, generally experimenting with their discoveries on humans in the field. Their ultimate goal is to win the arms race in order to either control or destroy all human civilization, even if to the point of annihilating all progress made by anyone other than themselves.
In the early 1960s, Dr. Hideki Hongou learned of Deathdark and their threat to humanity; abandoning his own pursuits, he formed the Future Science Laboratory to combat Deathdark while promoting constructive science for the betterment of society. The Future Science Foundation developed over twenty years until Hongou himself is targeted by Deathdark, forcing the activation of Goggle V in order to bring them down.
Deathdark's base of operations, Dark Giant Castle Deathtopia (暗黒巨大城デストピア Ankoku Kyodaijō Desutopia) is a mobile fortress that launches giant robots from its gate. It is usually underwater, but it can fly. When in flight, its high-power propulsion winds wreak destructive chaos underneath.
