Great Emperor Kubilai

Great Emperor Kubilai is the ruler of the Fushigi World Fuuma and the main antagonist of Uchuu Keiji Shaider.

History
Long ago, Kubilai ruled the ancient Mu Empire and brutally oppressed and corrupted the humans living under it until he was defeated by the warrior Shaider, who cut off his head from his body.

Embedding his head into the wall of the Fushigi Palace, Kubilai formed the Fuuma, a cult centered around him, to continue his conquest and one day recreate the Mu Empire. Kubilai and the Fuuma destroyed many planets across the universe before coming to Earth, where they faced opposition from the Galactic Union Police's newest Space Sheriff, who was also the descendant of the original Shaider.

Kubilai came close to conquering the entire universe, leadig Shaider to storm his palace and confront him. Kubilai was ultimately destroyed by Shaider stabbing him in his weak spot, his third eye, defeating the Fuuma before they could achieve universal domination.
