When he found the resting place of his ancient foe and the prison holding his body, Kubilai went to great lengths to ensure his weakness, his third eye, would not be revealed. When Shaider storms his palace, Kubilai unveils his robot body and takes Shaider into the Fushigi Dimension for an epic final battle. After detaching from his robot body, Kubilai meets his end when Shaider plunged his Laser Blade into Kubilai's third eye and then used Shaider's Blue Flash to finish him.
