Hundred Demons Empire

The Hundred Demons Empire are a powerful military force seeking to conquer the world and the main antagonists of the manga and anime Getter Robo G.

History
They were formed when a student named Burai discovered a downed alien UFO and was granted vast power and a demonic form by it. Reverse engineering its technology to construct a massive army, the now Emperor Burai began a campaign of global conquest, opposing both the Getter Team the Dinosaur Empire. Blocking them from achieving their goals of conquest was the super robot Getter Robo G.

After being unable to acquire the technology of the civilization of Atlantis, the Hundred Demons Empire opted to destroy it instead. However, this proved to be the cause of their downfall, as in an act of vengeance the Atlanteans gave the Getter Team access to their ultimate weapon, Uzahra, the guardian deity of Atlantis. With Uzahra on their side, the Getter Team succeeded in destroying the Empire's fortress and wiping out most of their army.
